Working Hours and Personal Protective Equipment Effect on Blood Cholinesterase Levels of Tobacco Plantation Workers

Introduction: Tobacco production is increasing in certain regions of Indonesia due to its high economic value. Tobacco and its products can have harmful effects on the health of consumers, producers and processing workers. Analysis of blood samples has shown that tobacco farmers are at risk of developing occupational diseases related to pesticide exposure and nicotine absorption through the epidermis of wet tobacco leaves. The aim of this study was to compare blood cholinesterase levels in tobacco plantation workers in relation to their working hours and use of personal protective equipment (PPE). Methods: This cross-sectional observational study was conducted in ten subdistricts in Jember district, Indonesia, and included 50 participants selected using proportional sampling. Spearman’s test was used to analyse the relationship between variables. Results: The significance value of the relationship based on Spearman’s test between working hours and blood cholinesterase levels of tobacco farmers in Jember was 0.058 > α (0.05). Meanwhile, the significance value of the relationship between working hours and complete blood count, specifically mean corpuscular haemoglobin concentration (MCHC), was 0.00 < α (0.05), and between PPE use and blood cholinesterase levels was 0.035 < α (0.05). Conclusion: Working hours were not associated with blood cholinesterase levels, but were associated with blood MCHC levels. Meanwhile, the use of PPE was found to be associated with cholinesterase levels in tobacco farmers.

Hematological Parameters in Adult Type 2 Diabetes Mellitus Patients Visiting a Tertiary Care Center of Western Nepal

INTRODUCTION Various mechanisms suggest changes in hematological profiles of Type 2 Diabetes Mellitus (T2DM) patients. Similarly, alterations in hematological profiles have been linked with pathogenic mechanisms in Diabetes. We aim to determine hematological profiles of adult MATERIAL AND METHODS This hospital-based cross-sectional study was conducted from March 2020 to December 2020 at the department of Pathology and Biochemistry of Universal College of Medical Sciences. After ethical clearance (UCMS/IRC/016/20), 90 adult patients diagnosed with T2DM were considered. Both verbal and written consent was taken. Type 1 diabetics, patients with history of hemoglobinopathies, recent blood transfusion, chronic illnesses and acute infections, and whose peripheral smear showed dimorphic pictures were excluded. The glycemic and hematological parameters were estimated. The data were analyzed using SPSS (version 20). Categorical data were expressed in frequency and percentage. Numerical data were expressed as median (interquartile range). Mann-Whitney U test was used to compare the hematological parameters between patients with good and poor glycemic control. RESULTS Among the total 90 participants, 34.4% had anemia. Mean Corpuscular Hemoglobin Concentration (MCHC) correlated positively with both Random Blood Sugar (RBS) and HbA1C. RBC count and Packed Cell Volume (PCV) were significantly higher in patients with good glycemic control, whereas MCHC was significantly lower in that group. CONCLUSION High prevalence of anemia was noted in T2DM patients. RBC and PCV levels were significantly lower in patients with poor glycemic control and MCHC levels were significantly lower in patients with good glycemic control.

Protective role of olive oil extract of propolis on short and long-term administration of tamoxifen in rats.

Tamoxifen (TAM) is an antiestrogenic agent used for adjuvant treatment in estrogen receptor-positive breast cancers in the pre/post-menopausal period. This study, it was aimed to determine the effect of olive oil extract of propolis (OEP) on short and long-term administration of TAM in rats. Wistar albino rats were divided into groups with eight animals in each. Groups: control, OEP, TAM, and OEP + TAM. At the end of the experiment, oxidative stress tests were performed with Enzyme-Linked ImmunoSorbent Assay (ELISA)on blood and tissue samples (liver, kidney, and ovary) taken from rats. After single-dose TAM administration, there was a significant increase in red blood cell, hematocrit, mean corpuscular hemoglobin, and mean corpuscular hemoglobin concentration levels compared to the control group, a decrease in low-density lipoprotein (LDL) value, a significant increase in liver enzymes and fasting glucose values was detected compared with the control and propolis groups. A normalizing effect was observed in the group given OEP and TAM combined. The increase in Malondialdehyde (MDA) and the decrease in enzyme activities in tissues are also noteworthy. Propolis application reduced the tissue damage caused by TAM. In addition, improved cytokine levels, which increased with TAM administration. It has been concluded that OEP can be given in supportive treatment, as it improves hematological and antioxidant parameters in TAM treatment.

Effect of Morinda citrifolia fruit powder on physiological and productive performance of Cavia porcellus.

The breeding of guinea pig is part of the pluriactivity for millions of farming families in rural areas from the Peruvian Andean and Amazonian regions and other South American Andean countries. Rearing these specie plays an important source of employment, income, and nutrition for millions of rural families on these countries. The search of natural products for enhancing animal wellbeing, health, and production and thereby of guinea pigs is being searched nowadays. The aim of this study was to determine the effect of the ripe fruit powder of Morinda citrifolia on the physiological and productive performance parameters of reared guinea pigs under humid tropical conditions and to find a new use of noni fruit and to improve the guinea pig as an agrifood product. For this purpose, forty-eight male Peru breed guinea pigs sixty days old, were used and distributed into four treatments with diets containing 0, 2, 4 and 8% of the noni ripe fruit powder, with four replicates and 3 guinea pigs each. Erythrocytes, hematocrit, hemoglobin profiles, hematological indices MCV (mean cell volume), MCHC (mean corpuscular hemoglobin concentration), MCH (mean corpuscular hemoglobin) and blood metabolites profiles: TP (total protein), ALB (albumin), GLO (globulin), TC (total cholesterol) were determined. The productive performance indices: DWG (daily weight gain), DCFI (daily concentrated feed intake), TFIFM (total feed intake of fresh matter) and TFIDM (total feed intake of dry matter), FRCFM (feed rate conversion for fresh mater) and FRCDM (feed rate conversion for dry matter) were evaluated. The guinea pigs were evaluated at 60, 75 and 90 days old. The interaction between noni fruit powder and the age of guinea pigs produced an increase in the erythrocyte, hematocrit, MCH and MCHC levels at 75 days old, (p < 0.05). The final weight and the daily weight gain increased, while the feed rate conversion for fresh and dry matter decreased, as the level of noni fruit powder in the diet increased until 4% (p < 0.05). Thus, the level of noni ripe fruit powder in the guinea pigs' diets had a positive effect on the erythrocyte, leucocytes, hematocrit, MCH, MCHC levels, the final weight, the daily weight gain, and the feed rate conversion of fresh and dry matter.

Urinary 3-phenoxybenzoic acid (3-PBA) levels and changes in hematological parameters in Korean adult population: A Korean National Environmental Health Survey (KoNEHS) 2012-2014 analysis.

Pyrethroid insecticides have been broadly used as pest control in agriculture and residential spaces, exerting high effectiveness of insecticidal property and relatively low toxicity to humans. Several animal studies suggested that exposure to pyrethroids may induce hematological abnormalities, thereby altering the number of blood cells and resulting in blood disorders. However, no epidemiologic study has reported on the effect of pyrethroid insecticide exposure on hematological changes, except for occupational exposure. This study aimed to investigate the effect of urinary 3-phenoxybenzoic acid (3-PBA) concentrations on hematological parameters in a representative South Korean adult population. We analyzed data from 6296 adults enrolled in the Korean National Environmental Health Survey (2012-2014). We employed multiple linear regression analysis to evaluate the association of urinary 3-PBA levels with eight hematological profiles: white blood cells (WBCs), red blood cells (RBCs), hemoglobin, hematocrit, platelets, mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH), and mean corpuscular hemoglobin concentration (MCHC). The urinary 3-PBA levels were negatively associated with WBC, RBC, and hemoglobin levels and positively associated with MCV levels. The direction and magnitude of the association between the 3-PBA and hematological parameters varied according to sex and age. The adverse effects of 3-PBA on hematological parameters were distinctive among males aged 60 years and older. In this age group, 3-PBA levels were negatively associated with the WBC, RBC, hemoglobin, hematocrit, and MCHC levels among males. This study is the first to verify that urinary 3-PBA concentrations at the levels found in a Korean population are associated with blood parameters. This finding merits further investigation to understand the impact of 3-PBA on human blood function and public health.

Evaluation of immune response and haematological parameters in infected male albino rats by giardiasis.

The present work aimed to study the effects of Giardia lamblia infection on immunological and haematological studies and to evaluate immunoglobulins and some cytokines. Fifty male albino rats were divided into six groups. The control group includes 20 rats and the infected group includes 30 rats. All the estimations were checked all over five checkpoints (CP) (7, 14, 21, 28 and 35days post-infection). Serum levels of IgA, IgG, IgM and IgE. Cytokines INF-γ, TNF-alpha, IL-4, IL-10 and haematological parameters were determined. Cyst and trophozoite were counted. A considerable increase in the level of immunoglobulins and cytokines in all infected groups compared with the control group was documented. Furthermore, a significant decrease in red blood corpuscles, haemoglobin and mean corpuscular haemoglobin concentration levels was observed, whereas substantial increases in mean corpuscular volume, mean corpuscular haemoglobin and platelets were observed. Moreover, infected rats had a substantial rise in WBCs, lymphocytes and eosinophil counts compared with the control group, whereas neutrophils and monocytes had a significant decrease. The number of trophozoites and cysts was significantly increased in infected groups before diminishing after day 28. The current results showed that Th1 and Th2 immune responses, which are characterized by the production of TNF-α, IFN-γ, IL-4 and IL-10, are important for protection against Giardia infections and also verified the balance between these cytokines and the timing of their production was crucial in G.lamblia immune response.

Associations between differences in anemia-related blood cell parameters and short-term exposure to ambient particle pollutants in middle-aged and elderly residents in Beijing, China

Anemia is a highly prevalent disease among older populations, with multiple adverse health outcomes, and particles exposure is a potential risk factor for anemia. However, evidence on associations of exposure to particles with small size with anemia-related blood cell parameters levels in the elderly is limited, and the underlying mechanisms are unclear. Based on a panel study in Beijing, we found that in 135 elderly participants, mass concentrations of particle with an aerodynamic diameter ≤ 2.5 μm (PM2.5), black/elemental carbon (BC/EC, particle size range: 0–2.5 μm), and number concentrations of ultrafine particles (UFPs, particle size range: 5.6–93.1 nm) and accumulated mode particles (Acc, size range: 93.1–560 nm) were significantly associated with levels of red blood cell count (RBC), hemoglobin (HGB), hematocrit (HCT), mean corpuscular hemoglobin (MCH), mean corpuscular hemoglobin concentration (MCHC). The mean ± SD for PM2.5, UFPs, Acc, BC, OC, and EC were 69.7 ± 61.1 μg/m3, 12.5 ± 4.3 × 103/cm3, 1.6 ± 1.2 × 103/cm3, 3.0 ± 2.0 μg/m3, 8.7 ± 6.7 μg/m3, and 2.1 ± 1.6 μg/m3, respectively. Cotinine (higher than 50 ng/mL) is used as an indicator of smoking exposure. The association between MCHC difference and per interquartile range (IQR) increase in average UFPs concentration 14 d before clinical visits was −0.7% (95% CI: −1.1% to −0.3%). Significant associations of UFPs and Acc exposure with MCHC and MCH levels remain robust after adjustment for other pollutants. Furthermore, 25.2% (95% CI: 7.4% to 64.8%) and 29.8% (95% CI: 5.3% to 214.4%) of the difference in MCHC associated with average UFPs and Acc concentrations 14 d before clinical visits were mediated by the level of tumor necrosis factor α (TNF α), a biomarker of systemic inflammation. Our findings for the first time provide the evidence that short-term UFPs and Acc exposure contributed to the damage of anemia-related blood cell in the elderly, and systemic inflammation was a potential internal mediator.

Associations between 3-phenoxybenzoic acid levels and hematological measures in adults: Korean National Environmental Health Survey 2012–2014

BACKGROUND AND AIM: Pyrethroid insecticides have been widely used for pest control in agriculture and residential spaces due to their high insecticidal effectiveness and low toxicity to humans. Several animal studies suggested that exposure to pyrethroids may induce bone marrow toxicity, resulting in inhibiting blood cell production. However, no studies have reported the effect of pyrethroid insecticide exposure on hematological changes in humans without occupational exposure. This study aimed to investigate the effect of 3-phenoxybenzoic acid (3-PBA) concentrations in urine on hematological parameters in Korea's representative adult population. METHODS: We analyzed data from 6,296 Korean adults recruited in the Korean National Environmental Health Survey (2nd round, 2012–2014). A multiple linear regression analysis was used to evaluate the association of urinary 3-PBA levels with eight hematological profiles of white blood cell (WBC), red blood cell (RBC), hemoglobin (Hb), hematocrit (Hct), platelet, mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH), and mean corpuscular hemoglobin concentration (MCHC). RESULTS:Urinary 3-PBA levels showed a negative association with WBC, RBC, Hb levels and a positive association with MCV levels. The association varied by sex and age. The adverse effects of 3-PBA levels on hematological parameters were more pronounced among men aged 60 years and older. Among this age group, 3-PBA concentrations were negatively associated with WBC, RBC, Hb, Hct, and MCHC levels in men. However, among adults aged below 60 years, no associations were found between 3-PBA concentrations and any of hematological measure in either male or female. The associations remained significant on sensitivity analysis after controlling other urinary chemicals. CONCLUSIONS:This is the first study reporting evidence that 3-PBA concentration in urine, at levels found in a Korean population, may influence blood cell counts. This novel finding merits further investigation to understand the impact of 3-PBA on human blood function and population health.

Prediction of intrahepatic cholestasis of pregnancy in the first 20 weeks of pregnancy

Aim Intrahepatic cholestasis of pregnancy (ICP) is a pregnancy-specific liver disease associated with a significant risk of fetal complications including pre-term delivery and fetal death. Typically, it was diagnosed in the third trimester of pregnancy. This study utilized characteristics from routine maternal examinations in the first 20 weeks’ gestation to predict ICP in pregnant women. Methods This is a retrospective case-control study. 13,329 medical records were collected on pregnant women presenting to the West China Second University Hospital between December 2017 and December 2018. After screening according to strict criteria, a total of 487 patients, 250 intrahepatic cholestasis of pregnancy cases, and 237 controls were selected for this study. We collected seven maternal characteristics indices for analysis and forty-three routine blood examination indices were obtained from routine hepatic, renal, and coagulation function examinations. The least absolute shrinkage and selection operator regression was applied for variable selection. Classification and regression trees, logistic regression, random forests, and light gradient boosting machines were fit for predictive modeling. We randomly divided 25% of the original data as testing set to conduct internal validation of the performance of the prediction model. The area under the receiver operating characteristic curves (AUC) was used to compare methods. Results Eight variables were selected out as potentially significant predictors that could reliably predict ICP. The sensitivity, specificity, accuracy, and AUC of the final prediction model obtained by light gradient boosting machines were 72.41, 79.69, 76.23, and 79.77%, respectively. Significantly higher platelet large cell ratio, alanine aminotransferase, glutamyl transpeptidase, and fibrinogen levels were found in cases as compared to healthy controls, while activated partial thromboplastin time and mean corpuscular hemoglobin concentration levels were significantly lower (p < .001). Conclusions The combination of alanine aminotransferase, glutamyl transpeptidase, fibrinogen, platelet large cell ratio, activated partial thromboplastin time, lactate dehydrogenase, creatinine, and mean corpuscular hemoglobin concentration levels can effectively predict ICP in the first 20 weeks of gestation. These could help provide direction for earlier detection and prevention of ICP.

CT assessment of the increased density of cerebral vessels in plateau region

In this study, the relationship between the brain parenchymal density, the cerebral vessel density, the mean corpuscular hemoglobin (MCH) content, the mean corpuscular hemoglobin concentration (MCHC), and the morbidity associated with lacunar infarction of residents living in either the plains or the plateau regions were analyzed and compared for their potential clinical implications. Clinical data from the brain CT scans of individuals living in either the plain or plateau regions (129 each) were collected. Specifically, the CT values for basal ganglia, the middle cerebral artery, and the superior sagittal sinus, along with the number of patients with lacunar infarction, were collected. In addition, the MCH and MCHC values were measured in blood samples collected within 48 h following the CT scans. For statistical analysis, an independent sample t-test, Pearson's correlation test (permutation test), and Chi-squared test were employed. The inhabitants of the plateau had a significantly higher CT value of basal ganglia, the middle cerebral artery, and superior sagittal sinus and also higher levels of MCH and MCHC in the blood (ps < 0.001) than the inhabitants of the plains region. Further, there was a significant positive correlation between the three aforementioned CT values and the MCH and MCHC findings. However, no significant differences were found in the morbidity of lacunar infarction between these two regions (p > 0.05). The inhabitants in the plateau have a significantly higher brain parenchymal density, higher CT value for cerebral vessels density, and higher blood MCH and MCHC levels in comparison with individuals occupying the plains. Concurrently, the parenchymal density and the CT values are shown to be positively correlated with the MCH and MCHC content in the blood.

Seasonal variations in hematological profile of Holstein dairy cows as an indicator for physiological status assessment

Abstract. This study aims to investigate, for the first time in Algeria, the effect of seasonal climatic changes on the hematological profile of Holstein dairy cows as an indicator for their physiological status assessment. The study was conducted between November 2018 and October 2019 and was performed on a lot of 14 dairy cows. Blood samples were collected quarterly during this study period. The data regarding seasonal changes in hematological parameters were not significant concerning red blood cell count (RBC), hemoglobin concentration (Hb) and mean corpuscular volume (MCV). However, variations were significant for hematocrit (HCT), mean corpuscular hemoglobin content (MCH), mean corpuscular hemoglobin concentration (MCHC) and blood platelets (PLT). The percentage of HCT was higher in autumn (27.99%) and spring (28.58%) compared to winter (26.52%) and summer (26.75%), (p&lt;0.05). MCH, MCHC and PLT levels were higher in summer compared to the other seasons (p&lt;0.05), (p&lt;0.01) and (p&lt;0.001), respectively. The highest number of WBC was generally observed in summer and autumn and the lowest in winter and spring (p&lt;0.01). The ratio neutrophils/lymphocytes (N:L) was equal to 1.01, 0.79, 0.98 and 0.89 in autumn, winter, spring and summer, respectively of which this difference was not significant. This study might be helpful for providing base line information on the hematological profile of dairy cattle for the evaluation of physiological status.

Evaluation of Platelet Indices and Complete Blood Count in Canine Mammary Tumors

Background: Malignant mammary tumors in humans and bitches cause hematological disorders such as anemia, erythrocytosis, thrombocytosis, hyperproteinemia, and leucopenia. Novel studies have been conducted on the predictive and prognostic values of platelet (PLT) indices in human breast cancer (HBC). However, there is little information about the alterations in hematological parameters in canine mammary tumors (CMTs). The aims of this study were to evaluate the platelet indices and complete blood count (CBC) parameters in bitches with and without mammary tumor and to assess the above mentioned parameters with regard to histological tumor types and grades.Materials, Methods &amp; Results: A total of 71 bitches were enrolled in this study. The bitches in the study group were divided into 2 groups which consisted of malignant epithelial mammary tumors (group EMT; n = 43) and malignant mixed mammary tumors (group MMT; n = 12). Control group (group C) consisted of clinically and gynaecologically healthy 16 bitches. Blood samples were obtained to perform the CBC and PLT indices analysis. Histopathological examinations were carried out under a light microscope. Histological tumor types and malignancy grades were classified. The bitches with mammary tumor showed significantly increased PLT values and decreased hematocrit (HCT), hemoglobin (HGB) and mean corpuscular hemoglobin (MCH) values versus the healthy ones, regardless of the tumor type. However, in comparisons with the group C, mean platelet volume (MPV) and mean corpuscular hemoglobin concentration (MCHC) values were different only in the group MMT, while plateletcrit (PCT) and mean corpuscular volume (MCV) values were different only in the group EMT. Also white blood cell (WBC), PLT and PCT values were higher than the referenced laboratory ranges in grade 3 tumors. In the presented study, MPV was considerably correlated with PLT, platelet distribution width (PDW) and PCT. Also, PCT and PLT had high sensitivity and specificity to distinct EMT and MMT from the healthy bitches.Discussion: Microcytic and hypochromic anemia occurs due to the decrease in the amount of HGB. Levels of MCV, MCH, and MCHC in the HBC group were reported to be significantly lower than in humans without breast cancer. Although anemia did not occur in EMT and MMT groups, obtained significances in the HCT, HGB, MCV, MCH, and MCHC levels between the bitches with and without mammary tumor were in line with the previous reports. In this study, WBC levels in grade 3 tumors were significantly higher than grade1 tumors (P &lt; 0.05). Whereas levels of WBC in grade 1 and grade 2 tumors were in referenced laboratory ranges, it was higher in grade 3. Increased level of WBC in grade 3 was supposed to be due to the rise in malignancy as previously reported. Thrombocytosis was detected in 48.83% and 41.66% of the bitches in EMT and MMT groups, respectively. The higher percentage of CMTs with thrombocytosis in this study might be due to the difference in referenced upper limit of PLT in previous studies. The elapsed time between tumor formation and clinical presentation could be another influencing factor. Although PLT and PCT values were not significant according to the histological grading in this study, both parameters were found to be higher in grade 3 than the normal reference values. Further studies conducted with higher populations may lead the differences in these parameters to significance. With the support of further studies, alterations in the above mentioned parameters in bitches may contribute in the diagnosis process, management of treatment and may constitute an easy way to have an idea about the prognosis of mammary tumors.

Dhatri Lauha in the management of iron deficiency anemia: A prospective open-label single-arm multi-center trial.

The burden of iron-deficiency anemia (IDA) remains persistently high in India due to the poor tolerability of oral iron supplementation. Therefore, more focus is required to explore traditional medicine for safe and effective options for managing IDA. To assess the clinical safety and efficacy of Dhatri Lauha in patients with IDA. An open-label, prospective, single-arm, multi-center trial was conducted at 12 centers with a sample size of 40 participants per study site. Patients with IDA aged 18-60 years with hemoglobin levels in the range of 6-10gm/dl, mean corpuscular volume (MCV) <80 fl, mean corpuscular hemoglobin concentration (MCHC) <34 μg/dl, serum ferritin <30 μg/dl and serum iron <50 μg/dl were included in the study. Dhatri Lauha 500 mg capsule was administered twice daily with lukewarm water after meals for 45 days. The primary outcome measure was the change in hemoglobin (Hb%) level from baseline to day 45. Secondary outcome measures included the change in MCV, MCHC, serum iron and ferritin levels, incidence of adverse events, and change in safety parameters (liver and kidney function tests). The mean (statistical) change in outcome measures from baseline to day 45 was compared using a paired sample t-test. Out of 458 participants enrolled in the study, 400 contributed to the final analysis. A significant difference was observed in the outcome parameters such as Hb%, MCV, MCHC, serum ferritin, and serum iron levels (P < 0.001) after 45 days of treatment. Mean Hb% changed from 8.46 ± 1.14 g/dl at baseline to 9.18 ± 1.61 g/dl on day 45 (P < 0.001). LFT and KFT were within the normal limits after the study period. No participant withdrew from the study due to adverse events. Dhatri Lauha is a safe intervention and can be expected to improve hemoglobin levels, red blood cell parameters, and iron stores in patients with IDA. Future RCTs with a larger sample size, standard care as control and a longer follow-up may produce more accurate and reliable results.

A botanical from the antiproliferative Cameroonian spice, Imperata cylindrica is safe at lower doses, as demonstrated by oral acute and sub-chronic toxicity screenings

BackgroundThe cytotoxicity of the root’s methanol extract of Imperata cylindrica (ICR). was previously reported in a panel of human cancer cell lines, including multi-drug resistant phenotypes. The aim of this study was to assess the acute and sub-chronic oral toxicity of methanol root extract of Imperata cylindrica.MethodsThe acute toxicity was carried out according to the experimental protocol of OECD. The plant extract was administered orally to female rats at a single dose of 5000 mg/kg for 14 days and the animals were observed for any behavioral changes or mortality. For sub-chronic toxicity study, ICR was orally administered daily to male and female rats at different doses (250, 500 and 1000 mg/kg per b.w.) for 30 days. During these treatment days the animals were observed for any appearance of toxicity symptoms; following the treatment period, animals were sacrificed for hematological, biochemical and histopathology analysis.ResultsFrom the results of the acute oral toxicity assay, ICR was found to be non-toxic at the dose of 5000 mg/kg b.w. During the period of sub-chronic toxicity test, observation of signs, behavior and health status of the animals showed no abnormality in the groups of animals treated with ICR as compared to the controls. Significant variation of the relative body weights of heart and kidney were observed at dose a 1000 mg/kg b.w. Significant decrease of aspartate aminotransferase, creatinine level, low density lipoprotein concentration, triglyceride and total cholesterol were observed. In males, we noticed a significant decrease of the level of granulocytes with an increase of lymphocytes and mean corpuscular hemoglobin concentration levels. Histological examinations performed on kidney and liver showed a normal kidney architecture and liver also presented a normal hepatic architecture with slight degeneration at a dose 1000 mg/kg b.w.ConclusionICR is safe for acute oral administration; however, for long-term oral administration, safety measures should be taken. Thus, oral sub-chronic exposure of ICR at lower doses are recommended while higher doses around 1000 mg/kg b.w. should be discouraged.

Effects of Curcumin on Hematological Parameters in Aflatoxin B1 Applied Rats

In this study, it is aimed to determine the possible effects of curcumin on hematological parameters in aflatoxin applied rats. Thirty eight healthy male Wistar Albino rats were used in the study. Group I animals was no applied. Animals in Group II were orally given 1 ml 10% DMSO daily for 60 days. Animals in Group III were orally given 300 mg/kg curcumin dissolved in 10% DMSO daily for 60 days. Animals in Group IV were orally given 250 µg/kg aflatoxin B1 dissolved in 10% DMSO daily for 60 days. Animals in Group V was orally given 250 µg/kg aflatoxin B1 dissolved in 10% DMSO and 300 mg/kg curcumin dissolved in 10% DMSO daily for 60 days. At the end of the study, erythrocyte count, leukocyte count, platelet count, hemoglobin amount, hematocrit value, percentage ratios of leukocyte types, mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH), mean corpuscular hemoglobin concentration (MCHC) were determined in blood samples taken from all animals. In the study, erythrocytes count, hemoglobin concentration, hematocrit value and MCHC level in the aflatoxin applied rats significantly decreased compared to the control group (p<0.05). MCV level in the aflatoxin applied rats was found significantly higher compared to the control group (p<0.05). In the group in which aflatoxin and curcumin were administered together, erythrocytes count, hemoglobin concentration, hematocrit value and MCHC levels were found to be significantly higher compared to the group administered only aflatoxin (p<0.05). In the study, the leukocyte count significantly decreased in the aflatoxin group compared to the control group (p<0.05). Granulocyte and monocyte percentage significantly increased depend on aflatoxin application (p<0.05). In the group in which aflatoxin and curcumin were administered together, the leukocyte count significantly increased compared to the aflatoxin group (p<0.05). We concluded that curcumin may alleviate the abnormalities in hematological parameters resulting from aflatoxicosis.

The prognostic roles of red blood cell-associated indicators in patients with resectable gastric cancers.

BackgroundGastric cancer (GC) is one of the leading causes of cancer-related death worldwide. This study was designed to investigate the prognostic values of red blood cell (RBC)-associated indicators, including RBC, hemoglobin (HGB), hematocrit (HCT), mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH), mean corpuscular hemoglobin concentration (MCHC), and RBC distribution width (RDW) in resectable GC patients.MethodsIn this retrospective study, a total of 104 pathologically confirmed GC patients were recruited. These cases were divided into two groups according to the median values of pretreatment RBC, HGB, HCT, MCV, MCH, MCHC, or RDW. To evaluate the changes in RBC-associated indicators values after treatment, we introduced the concept of post-/pre-treatment ratios (≤1 suggested RBC, HGB, HCT, MCV, MCH, MCHC, or RDW values were not increased after therapy, while >1 represented those in increased levels).ResultsThe lower pretreatment MCHC levels were correlated with worse overall survival (OS), while pretreatment levels of RBC, HGB, HCT, MCV, MCH, or RDW were not. The whole course of treatment (surgery plus adjuvant chemotherapy) significantly decreased the values of MCHC, and increased the values of MCV and RDW, whereas it had no obvious effects on the values of RBC, HGB, HCT, or MCH. Patients with post-/pre-treatment MCV ratio >1 had an increased survival ratio. Meanwhile, post-/pre-treatment RBC, HGB, HCT, MCH, MCHC, or RDW ratios were not correlated with outcomes. Multivariate Cox regression analysis revealed that the American Joint Committee on Cancer (AJCC) stage (III), and lower pretreatment MCHC levels were independent risk factors affecting OS. The receiver operating characteristic (ROC) curve analysis showed that an MCHC value of 341.98 g/L was the optimal cutoff value for prognosis, with a sensitivity of 58.3% and a specificity of 75.0%.ConclusionsPretreatment MCHC levels could become a potential prognostic factor for resectable GC.

TEKRARLAYAN DÜŞÜK VE TAM KAN SAYIMI DEĞERLERİ ARASINDA HERHANGİ BİR İLİŞKİ VAR MI? BİR VAKA-KONTROL ÇALIŞMASI

Objective: It was aimed to examine the relationship of complete blood count values with recurrent miscarriage.Method: We carried out a case-control study of patients who had recurrent miscarriage between 2010-2018. Data were collected from 50 patients who were meeting the case group inclusion criteria, and age-matched healthy control group with at least one live birth who consisted of 60 women. Red blood cell (RBC), hemoglobin (HB), hematocrit (HTC), mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH), mean corpuscular hemoglobin concentration (MCHC), platelet count (PLT), platelet distribution width (PDW), mean platelet volume (MPV), red cell distribution width (RDW) and plateletcrit count (PCT) were examined by complete blood count. SPSS 20.0.0 software was used for statistical analysis. P values &amp;lt;0.05 were regarded as statistically significant.Results: The mean age of the case group was 29.8±5.8 years, and the mean age of the control group was 28.7±5.2 years (p&amp;gt;0,05). MPV and RDW values and PCT calculations were significantly higher than healthy control group (p&amp;lt;0.05). MCHC levels of case group were lower than control group (p&amp;lt;0.05). There were no significant differences between the case and control groups in terms of RBC, HB, HCT, MCV, MCH, PLT, and PDW (p&amp;gt;0.05). Conclusion: Complete blood count parameters such as high MPV, RDW, PCT, and low MCHC could be considered as an important predictor of recurrent miscarriage. Our findings should be supported by further prospective studies involving a larger number of patients in order to clarify the relationship between these blood cell function markers and recurrent miscarriage.

Assessment of rheological indices of chickens (Gallus gallus domestica) exposed to factory sites in Nnewi, Anambra State, South Eastern Nigeria

This study examined the rheological indices of chickens exposed to factory sites in Nnewi Nigeria. A total of twenty-nine (29) chickens aged four (4) to five (5) months comprising of 16 chickens exposed to factory sites and 13 non exposed chickens (control birds) were used for the present study. Five (5) ml of blood sample was collected from the heart of the animal into EDTA containers for the evaluation of rheological indices under study. The red cell count (RCC), hemoglobin (Hb), packed cell volume (PCV), mean corpuscular hemoglobin concentration (MCHC), total white blood cell (TWBC) and lymphocyte levels were assayed by using Mythic 22 automated hematology analyzer observing standard laboratory practice. The RCC and lymphocyte levels of the factory chickens were significantly increased (p0.05) between the Hb, PCV, MCHC and TWBC levels of the factory chickens and the control birds respectively. These results may be attributed to the short duration of this study and the fact that these chickens were not directly exposed to these industrial effluents.

Do MCHC, MPV, and Procalcitonin Levels Determine Prognosis in Acute Coronary Syndrome?

Aim Acute coronary syndrome (ACS) continues to be the main cause of mortality and morbidity globally. The aim was to assess serum procalcitonin (PCT), mean corpuscular hemoglobin concentration (MCHC) and mean platelet volume (MPV) levels in terms of complications after myocardial infarctus, triple vein coronary artery disease (TVCAD), and mortality prediction. Material and Method This cross-sectional cohort study included 200 patients with ACS attending the emergency department of our hospital with chest pain and admitted to the cardiology clinic from January 2014 to December 2016. Patients were divided into 4 groups as inferior group, anterior group, NSTEMI group, and UA group according to diagnosis. These groups were compared in terms of complications occurring after MI, TVCAD, and mortality rates. Results There were significant differences in terms of complications forming after ACS, TVCAD, and mortality. The inferior subgroup had high PCT and MCHC levels and was found to have more complications developing and mortality compared to other groups. Patients with high PCT and MPV values were identified to have higher mortality and TVCAD. In the anterior subgroup, ischemic heart failure was higher compared to the other groups. In the interior, anterior, and non-ST elevated myocardial infarctus (NSTEMI) groups, the 0-, 6-, and 12-hour cTnI values were significantly higher compared to the UA group, while the anterior group had a significantly higher 12-hour cTnI value compared to the NSTEMI group. Correlation analysis for PCT, MCHC, and MPV with complications developing after MI, mortality, and TVCAD found positive and statistically significant correlations. Conclusion High PCT, MCHC, and MPV levels in acute coronary syndrome may be beneficial predictive values in terms of complications that may develop, TVCAD, and mortality.

The association between iron deficiency anemia and febrile seizure.

Different studies have reported contradictory results regarding the relationship between iron deficiency anemia (IDA) and febrile seizure (FS). The present study was conducted to determine the effect of IDA on FS in children. This case-control study was conducted among 52 children with FS (the case group) and 18 children with afebrile seizures and 51 children with fever without seizures in the age range of 6 months to 5 years admitted to the pediatric ward of Imam Khomeini Hospital in Ilam from March 2016 to January 2017. Patients were selected using the convenience sampling method. Red blood cell (RBC) count as well as measurement of hemoglobin (Hb), hematocrit (Hct), ferritin, mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH) and mean corpuscular hemoglobin concentration (MCHC) levels were performed in all patients. The collected data were analyzed using SPSS16 software. A total of 34.6% in the FS group, 66.7% in the afebrile seizure group and 41.2% in the fever without seizure group suffered from IDA, which was not statistically significant between the three groups. Hb, Hct and RBC levels were higher in the case group and MCV, MCH, MCHC levels in the case group were lower than those in the control group. The odds ratio (OR) for FS compared to the febrile group was 0.756 [95% confidence interval (CI) = 0.34-1.68; p = 0.493] and that for FS compared to seizure was 0.265 (95% CI = 0.085-0.823; p = 0.022). This study showed that IDA may have protective effects on the onset of FS, and based on the results, IDA is more common in children with afebrile seizures. Further and more comprehensive studies are recommended.
