Water temperature fluctuations as a key driver of cetacean pox (tattoo) lesions in bottlenose dolphins Tursiops truncatus.

Dolphin tattoo lesions are superficial non-raised skin lesions caused by poxviruses. Their presentation can vary but typical lesions in bottlenose dolphins are circular to ovoid with concentric rings of black stippling. These lesions have at times been suggested as an indicator of overall dolphin health and welfare. This study explored the effect of water temperature on the extent of tattoo lesions in 25 dolphins, along with established hematological health parameters and food consumption. Study animals consisted of 9 males and 16 females with dolphin tattoo lesions ranging in age from 2 to 45 yr. A significant decrease (p < 0.01) in extent and appearance of tattoo lesions was documented following increase in water temperature from 21-24°C (70-75°F) to 25.5-26.5°C (78-80°F). Reduction in tattoo lesions could be noted as early as 2-3 wk following water temperature increase. Marked reduction to complete resolution of tattoo lesions was reproducibly seen 5-6 wk post temperature increase. Food consumption following temperature increase was variable: decrease in intake was noted in 48% of dolphins, increase in intake in 52%. Routine blood parameters (complete blood count, serum chemistry panel, fibrinogen, erythrocyte sedimentation rate) remained within normal limits. A significant increase (p < 0.05) in extent and appearance of tattoo lesions was documented in 3 dolphins as early as 4-5 wk following a decrease in water temperature from 26.1°C (79°F) to 21°C (70°F). Water temperature is a key environmental parameter affecting cetacean pox ('tattoo') lesions in bottlenose dolphins. The absence of changes in hematological parameters along with lack of correlation between extent of pox lesions and food intake indicates that dolphin tattoo lesions are not an appropriate indicator of overall health.

Malaria Parasite Density as a Predictor of Hematological Parameter Changes among HIV Infected Adults Attending Two Antiretroviral Treatment Clinics in Kano, Northwest Nigeria.

Background Despite public health significance of dual infections of human immunodeficiency virus (HIV) and malaria in developing countries like Nigeria, information on the association between malaria parasite density count (MPDC) and hematological parameter changes among HIV-infected individuals is rarely available. Objectives To evaluate burden of HIV and malaria dual infections and assess the predictive association of MPDC with hematological parameter changes among HIV infected adults attending two antiretroviral treatment clinics in Kano, Nigeria. Methodology. This was a cross-sectional study consisting of 1521 consented participants randomly selected between June 2015 and May 2016. Participants' basic characteristics and clinical details were collected using a pretested and validated standardized questionnaire. Collected venous blood was analyzed for malaria by rapid testing and microscopy including malaria parasite density; hematological parameters were estimated using a Sysmex XP-300 autoanalyzer. Data was reviewed, cleaned, and analyzed using SPSS software version 23.0. Mean hematological parameters and HIV/malaria status were compared using the independent t-test; hematological parameters and MPDC relationship was tested by simple linear regression analysis. Statistically significant difference at probability of <0.05 was considered for all variables. Results The majority (70.6%) of the participants were females. Mean (SD) age was 37.30 ± (10.41) years and ranged from 18 to 78 years. 25.4% of participants had dual infection, 99% due to Plasmodium falciparum species. Mean MPDC was 265 ± 31.8 (SD) cells/μl and ranged from 20 to 2500 cells/μl. Dual infection was highest (37.5%) among respondents in the age group ≥60 years. Prevalence was similar among other age groups (p = 0.165) and gender (p = 0.942). Of the 16 hematological parameters evaluated, 11 showed significant difference between HIV mono-infected and dual infected participants. Of the 11 parameters, only 7 (Hb, MCHC, red cells count, neutrophil and lymphocyte percentage, absolute lymphocyte count, and red cell distribution width) were significantly predictive of changes with respect to MPDC. Conclusions MPDC was significantly predictive of changes in 7 hematological parameters among dual infected participants in these settings. In routine malaria diagnosis, MPDC determination with respect to changes in some hematological parameters should be considered in ART programs for improved patient management.

Thermoregulatory Responses of Heat Acclimatized Buffaloes to Simulated Heat Waves.

Simple SummaryThe simulated heat wave triggered a relevant thermoregulatory response in heat-acclimatized buffaloes. During the simulated heat wave the high respiratory rate and seating rate limited the heat storage and the levels of hyperthermia. Moderate and transient hyperthermia combined with complete recovery of homeothermy during the night prevented changes in blood parameters, except for ion potassium. The high sweating rates seem to have been crucial for the homeothermy’s maintenance. For the first time, early in the morning, adaptive hypothermia was recorded in buffaloes.Climate change is seen as a significant threat to the sustainability of livestock production systems in many parts of the world, particularly in tropical regions. Extreme meteorological events can result in catastrophic production and death of livestock. Heat waves in particular can push vulnerable animals beyond their survival threshold limits. However, there is little information about buffalo responses to sudden changes in the thermal environment, specifically the heat waves. This study aimed to quantify the thermoregulatory and blood biochemical responses of heat-acclimatized buffaloes to a simulated heat wave. The experiment was designed in a climatic chamber with two periods of 4 days each. Twelve heat acclimated buffalo heifers aged 18 months were used. The climatic chamber environment was set as follows: 4-day period (P1) simulating the same weather conditions of a summer in humid tropical climate used as a baseline, with daily cycle with Ta and RH at 27 ± 1 °C and 76% from 0600 h to 1900 h and 24 ± 1 °C and 80% from 1900 h to 0600 h, and 4-day period (P2), simulating a daily heat wave cycle, from 0600 h to 1900 h with Ta and RH kept at 36 °C and 78% and from 1900 h to 0600 h, 27 °C and 74%. All animals were subject to both treatments and data were analyzed by a repeated measure analysis of variance, with post-hoc pooling comparison performed by Tukey’s test. In P2, there was observed a significant increase in respiratory frequency (p < 0.01), found four times in P1. The sweating rates were quite high in both periods; still, there were significant increases in P2 compared to P1 (p < 0.01) (4931 and 3201 g/m2/h, respectively). A slight but significant increase in rectal temperature was observed during the day (p < 0.01), with a rising until 1900 h. The simulated heat wave in P2 did not affect the values of the erythrogram or leukogram, excluding the significant reduction in K+ (p < 0.05). The low heat storage and the subsequent fast and full recovery of the thermal balance late afternoon appear to be related to the high sweating rate values. The massive sweating rate emphasizes its relevance in the maintenance of buffalo homeothermy. The absence of changes in hematological parameters has revealed the considerable physiological resilience of buffaloes toward simulated heat waves.

A Pilot Study Indicating Valuation of C‑Reactive Protein for Disease Outcome in Sickle Hemoglobin Patients of Central India

Evidences support the fact that sickle cell disease (SCD) is associated with a chronic inflammatory state characterized by haemolysis. C-reactive protein level (CRP) and white blood cell (WBC) count considered as biomarkers for inflammation. Also, elevation of serum total lactate dehydrogenase (LDH) levels are found to be associated with haemolysis, this makes LDH a nonspecific marker which has to be interpreted in a context of other markers of disease. The present study aims to assess the role of CRP levels, WBC counts, RBC counts, haemoglobin (Hb) concentrations and LDH levels in sickle hemoglobin (HbS) patients. Blood samples of 10 HbS patients (six females and four males) attending M.Y. Hospital, Indore during the period of Aug to Oct 2019 were screened for CRP, LDH and Hb levels and RBC and WBC counts using latex enhanced immune-turbidimetric assay, LDH optimize DGKC kinetic and differential automated hematology analyzer respectively. Data (mean ± SEM) was analyzed using Graphpad Prism software using Tukey’s multiple comparison post-hoc test. The mean Hb levels (7.73 ± 0.81 g/dl) and RBC counts (3.21 ± 0.53 million/µl) were found to be significantly decreased (p˂ 0.001 and 0.01 respectively) and mean WBC counts (15214.28 ± 1893.40 per mm3), CRP levels (85.73 ± 23.23 mg/l) and LDH levels (1334.00 ± 418.49 U/l) were found to be significantly increased (p˂ 0.0001, 0.01 and 0.01 respectively) in HbS patients in comparison with their respective controls. The variations in serum LDH and CRP levels are accompanied by changes in hematological parameters in HbS patients. These parameters may be considered as indicator of the severity of the disease.&#x0D; Keywords: C-reactive protein, LDH, Sickle cell disease

Does H. pylori therapy augments the effect of iron therapy among children with iron deficiency anemia?

Background: To assess beneficial effects of H. pylori therapy on children with pre-existing Iron Deficiency Anemia (IDA).Methods: A total of 218 consecutive patients with iron deficiency anemia (Hb 6-11 gm/dl) were invited to participate in the study. Patients underwent endoscopic biopsy and rapid urease test for H. pylori detection. A total of three groups were formed- Group I (n=13) - positive for H. pylori, underwent treatment for H. pylori therapy and IDA, Group II (n=16) - positive for H. pylori, underwent treatment for IDA only, Group III (n=101) - negative for H. pylori, underwent treatment for IDA only. All the patients were followed up after every 4 weeks till week 12. Change in haematological parameters and anaemic and iron status was assessed. Chi-square paired ‘t’-test and ANOVA were used using SPSS 21.0.Results: All the 3 groups showed a significant increase in S. Hb, Ferritin and iron levels and a decrease in S. TIBC levels. At 12 weeks, mean S. ferritin and S. iron levels were significantly higher in Groups I and III as compared to Group II while Mean S. TIBC levels were significantly higher in Group II as compared to that in Groups I and II. A total of 73.3% of Group III, 53.8% of Group I and 56.3% of Group II patients had hemoglobin levels &gt;11 g/dl, but difference was not significant (p=0.175).Conclusions: The findings of study showed that H. pylori therapy augments the effect of iron therapy among H. pylori positive children with iron deficiency anemia.

Haematological changes in transhumant Baruwal sheep (Ovis aries) grazing in the western Himalayan mountains in Nepal

Transhumance pastoralism is a traditional sheep management strategy adopted by the herders in the Himalayas to address environmental stress. The changes in haematological parameters in the transhumant sheep may well give insights of changes in physiological changes at pasture sites of various elevations in the transhumance cycle. For that purpose, 32 healthy Baruwal sheep were selected and divided into four groups: male (8) below 1 year, male (8) greater than 1 year, female (8) below 1 year, and female (8) greater than 1 year; the animals were selected based on similarity on body weight within the groups. The herd was clinically inspected for the presence of any infection. Adaptation period was set for 3 weeks at each pasture site. The blood samples were taken from designated groups at both grazing sites, i.e. from low (2431 m.a.s.l) to high stopover (3885 m.a.s.l) at the seventh day of the experimental period. Climatic data were recorded at both altitudes over the period of measurements from manually installed weather stations. Later, the herbage species were collected based on the visual sign of grazing at both sites and subjected to chemical composition analysis. The research results revealed that RBC (red blood cell), Hb (Haemoglobin), and PCV (packed cell volume) were significantly increased (p < 0.05) at high altitude, while MCH (mean corpuscular haemoglobin) and MCHC (Mean corpuscular haemoglobin concentration) were higher at low altitude. Sex and age had a similar effect (p > 0.05) on haematologic parameters, except for PCV and MCH. The altitude had a big impact on leucocyte (p < 0.05), being greater at low altitude than high, which could be an indicator of the increased immunologic response at low altitude irrespective of age and sex. The research result revealed the changing haematological responses of Baruwal sheep to changing pasture sites at different altitudes in the transhumance movement. The results further gave a hint of the nutritional stress at low altitude when the herd arrives in the winter season. It is rather difficult to draw an immediate conclusion that pasture quality might be the contributory issue for a decline in the nutritional status of grazing sheep when the herbage species vary by altitude. The measurement of blood metabolic stressors could further facilitate description of the nutritional stress alongside the transhumance when the grazing species and quality are different. Strategic feed supplementation for a much better performance of Baruwal sheep is needed at low altitude to deal with the declined herbaceous quality during winter.

Effect of Cardisoma guanhumi (Land Crab) Extract on Haematology and Lungs Histology in Swiss Mice Infected with Bordetella pertussis

Pertussis is an acute human respiratory tract disease caused by Bordetella pertussis, a known international pathogen that affects infants, children and adults. This study is aimed at investigating the changes in haematological parameters and histopathological changes of the lungs connected with Bordetella pertussis infection in swiss mice and to evaluate the potential of Cardisoma guanhumi extract to reverse these adverse changes about erythromycin treatment. The animals were divided into five groups: Group 1 was normal to control, group 2 was infected with Bordetella pertussis without treatment (negative control), group 3 and 4 were Bordetella pertussis infected and treated with 300 mg/kg and 600 mg/kg of the extract respectively and group 5 were infected and treated with 4000 mg/70 kg of erythromycin in divided doses. The animals were inoculated with a single infectious dose of Bordetella pertussis bacteria and were consequently treated with the graded doses of the extract and erythromycin for eighteen days after the animals were confirmed infected. The mice were humanely sacrificed using diethyl ether anaesthesia and blood samples were taken for liver function investigation and liver tissue harvested and processed for histological examination. The result showed that Cardisoma guanhumi extract reversed the changes in the haematological parameters and pathological changes in the lungs of mice infected with Bordetella pertussis in a dose and time-dependent manner which suggests prophylactic and curative potentials of Cardisoma guanhumi extract against B. pertussis.

Iron deficiency-induced thrombocytosis increases thrombotic tendency in rats.

Iron deficiency (ID) is globally prevalent, and apart from anemia is associated with thrombocytosis. While considered benign, studies linking thrombotic events with prior ID anemia suggest otherwise. In this study we used animal models to assess the influence of ID on thrombotic tendency. Sprague-Dawley rats were fed control or iron-deficient diets and ferric carboxymaltose was used to reverse ID. Thrombosis was induced by stenosis of the inferior vena cava or damage to the right carotid artery using ferric chloride. Thrombi were evaluated histologically and by high frequency ultrasound in the venous model. ID consistently induced thrombocytosis alongside anemia. The growth of venous thrombi and the final dimensions of both arterial and venous thrombi were greater in animals with ID. In both models, platelet numbers correlated with the final thrombus size, with thrombi in iron-deficient animals having the largest platelet areas. Platelet function was also evaluated in surgically-naïve rats. Coagulability, determined by thromboelasto - graphy, and hemostasis, evaluated by tail transection, were enhanced in the animals with ID. Platelet P-selectin expression and plasma P-selectin levels were both higher in animals with ID. Platelet adhesion and aggregation in ID was impaired under shear flow but was intact in static assays. Iron replacement therapy reversed all ID-related changes in hematologic parameters, thrombus dimensions, and platelet assays. In summary, ID alone increases thrombotic tendency. Iron replacement therapy reverses these changes, making it a viable strategy for the prevention of ID-related thrombotic disease. This may be of importance in patients with chronic illnesses who may already be at increased risk of thrombosis, such as those with inflammatory bowel disease, chronic kidney disease, or cancer.

Effects of three herb-based alcoholic beverages manufactured in Ghana on sperm characteristics and reproductive hormones in rats

BackgroundAdvertisements of most alcoholic beverages in Ghana persuasively entice consumers with herbal constituents believed to enhance sexual performance, although, alcohol has negative effect onfertility. The impact of herbal constituents in these alcoholic beverages on the known negative effects of alcohol on fertility remains to be evaluated. This study evaluated the effects of three alcoholic beverages manufactured in Ghana on male reproductive function in rats. MethodsMale Sprague-Dawley rats received 0.5, 2.5 or 5 ml/kg of 3 herb-based alcoholic beverages (Brand A, B & C), 42% v/v ethanol or distilled water p.o. for 21 days. On day 22, blood was collected and assayed for serum prolactin, testosterone and, hematological parameters. Testes were removed for histology and sperm from the cauda epididymis analyzed for sperm count, motility and morphology. Total antioxidant capacity of the testes was determined. ResultsThe three alcoholic beverages did not cause any changes in hematological parameters and relative weight of the testes. However, Brand C reduced epididymal sperm count and increased serum prolactin and induced loss of germinal epithelial cells, necrosis, inter-tubular edema in seminiferous tubules and lipid and fluid accumulation in the Sertoli cells. Both Brands A and B caused tubular atrophy and enlarged spermatogonia at 5 ml/kg. All three brands significantly (p<0.001) reduced sperm motility and serum testosterone, although they increased total antioxidant capacity. ConclusionThe herb-based alcoholic beverages evaluated did not enhance or exert a beneficial effect on male reproductive function but rather demonstrated spermatotoxic properties irrespective of the presence of medicinal plants.

Haematological Profile of Adults with Malaria Parasitaemia Visiting the Volta Regional Hospital, Ghana.

Background Malaria is known to cause severe health consequences due to its marked effects and alteration on the haematological parameters of infected individuals. This study evaluated the haematological profile of adult individuals infected with the malaria parasite. Methods A retrospective study was conducted using archived data of malaria positive cases from January 2017 to March 15, 2019. Data retrieved included subjects' demographics, malaria parasite count, malaria parasite species, and full blood count parameters. A total of 236 malaria positive subjects were included in the study. Results The study showed that more females were infected with the malaria parasite than males (69.07% and 30.93%, respectively). A total of 87.3% of the study population were infected with Plasmodium falciparum as compared to 12.7% infected with Plasmodium malariae. The commonest haematological abnormalities that were seen in this study were lymphopenia (56.78%), anaemia (55.51%), thrombocytopenia (47.46%), eosinopenia (45.76%), neutropenia (29.24%), monocytosis (21.19%), and leucocytosis (17.37%) in the infected subjects. The mean platelet count of P. falciparum-infected subjects was decreased as compared to the mean platelet count of P. malariae-infected subjects. There was a significant (P value <0.05) decrease in the number of platelet count with every unit increase in parasite density. Conclusion Study participants infected with malaria demonstrated vital changes in haematological parameters with anaemia, thrombocytopenia, lymphopenia, monocytosis, and eosinopenia being the most important predictors of malaria infection especially with P. falciparum species.P. falciparum-infected subjects was decreased as compared to the mean platelet count of

Effect of Goniopsis Pelli (Marine Crab) Extract on Hematology and Lungs Histology in Swiss Mice Infected with Bordetella Pertussis

Pertussis is a global endemic infectious disease with outbreaks every 3–5 years is associated with lungs inflammations and hematological alterations. This study is aimed at investigating the changes in hematological parameters and histopathological changes of the lungs associated with Bordetella pertussis infection in swiss mice and to evaluate the ability of Goniopsis pelli extract to reverse these adverse changes in relation to erythromycin treatment. The animals were divided into five groups: group 1 was normal control, group 2 was infected with Bordetella pertussis without treatment (negative control), group 3 and 4 were Bordetella pertussis infected and treated with 300mg/kg and 600mg/kg of the extract respectively and group 5 was infected and treated with 4000mg/70kg of erythromycin in divided doses. The animals were inoculated with a single infective dose of Bordetella pertussis bacteria and were consequently treated with the graded doses of the extract and erythromycin for a period of eighteen days, after the animals were confirmed infected. The mice were humanely sacrificed using diethyl ether anesthesia and blood samples taken for hematological investigation and lungs tissue harvested and processed for histological examination. The result shows that Goniopsis pelli extract reversed the changes in the hematological parameters and pathological changes in the lungs of mice induced by Bordetella pertussis infection of in a dose and time dependent manner which suggests that prophylactic and curative potentials of Goniopsis pelli extract against B. pertussis.

The effect of heat stress on hematological parameters and oxidative stress among bakery workers.

Heat stress causes physiological changes, and changes in hematological parameters and hormonal levels in the human body, known as thermal strain. This study was conducted to determine the effect of exposure to heat stress on hematological parameters and oxidative stress in the bakers of Shahroud City, Iran. A total of 163 bakery workers (exposed group) and 135 office workers (unexposed group) with a minimum of 1-year working experience were selected. Exposure to heat stress was measured using ISO-7243 criteria on the hottest days of the year (late July and August). Wet-bulb globe temperature (WBGT) was calculated based on indoor environments. Oxidative stress indices including malondialdehyde (MDA), nitric oxide (NO), total antioxidant capacity (TAC) in the bakers' and office workers' serum and hematological parameters were measured. Statistical analysis was done through independent t-test, and multivariate linear regression using SPSS v24. Analysis of hematological parameters showed that about 70% and 68% of the bakers had abnormal mean cell volume (MCV) and white blood cell (WBC) count, respectively, while only around 12% of them had abnormal mean cell hemoglobin concentration (MCHC). The counts of red blood cells (RBC), WBC, lymphocytes (LYM), and MCV showed significant differences in different occupational groups (p < 0.05). The levels of MDA and NO were significantly higher in bakers with WBGT more than the threshold value (p < 0.05). The WBGT index for assessing heat stress can be used as a predictor variable for MDA and NO levels. In addition, heat stress exposure could be a risk factor for abnormal WBC, RBC, LYM, and MCV.

Haematological Derrangement Due to &amp;lt;i&amp;gt;P. falciparum&amp;lt;/i&amp;gt; Infection in Patients of Selected Health Centres in Ardo-Kola Local Government Area, Taraba State

Malaria infection is one of the most common disease of public health importance afflicting millions of people in sub-Saharan Africa. This study investigated haematological derrangement among malaria infected and non-infected patients attending some Primary Health Centres in Ardo-Kola LGA, Taraba State, Nigeria. 585 blood samples were collected and examined for <i>Plasmodium falciparum</i> infection. Packed Cell Volume (PCV) was done by microhaematocrit and Erythrocyte Sedimentation Rate (ESR) using Westergen methods. The overall result showed a prevalence of ESR by Westergern method. It was found that malaria with low intensity of parasitaemia infection, 217 (37.09%) was more than medium and high intensity of parasitaemia with no significant difference (χ²=9.34; P≥0.05). The mean value of haematological parameters of parasitized subjects were 0.29 for PCV and 124.3655 for platelets which were significantly lower than those of non-parasitized subjects, PCV=0.4577 and Platelets=198.7698 respectively. Erythrocyte Sedimentation Rate (ESR) was higher (33.0852) in parasitized subjects than non-parasitized (20.0504). The result of this study could be useful in identification of high-risk malaria population. This will target intervention and assessment of impact based on changes in haematological parameters associated with <i>P. falciparum</i> infection. Futhermore, preventive strategies like chemoprophylaxis, provision of iron supplementation and insecticide treated nets could be employed in the study area to curb the upsurge in transmission.

HEMATOLOGICAL CHANGES OF ENDOGENIC INTOXICATION, NON-SPECIFIC REACTIVITY AND INFLAMMATION ACTIVITY INDICES IN HIV-INFECTED PATIENTS

The aim: To establish changes in hematological parameters of endogenous intoxication, nonspecific reactivity, activity of inflammation in HIV-infected persons, to improve verification of the clinical stage of the disease. Materials and methods: Anamnestic, clinical, laboratory data. The statistical processing was performed in the Microsoft Office Excel 2010 and IBM SPSS Statistic 23 computer software, variational statistics processing (Student's t-criteria). Results: 51 HIV-infected were examined (main group) and 44 clinically anamnestic healthy blood donors (comparison group). The study included 46 patients (5 were withdrawn due to failure to meet criteria - severe septic condition). All patients were divided into three groups: A1 - all patients, 46 persons, men 76.0%, women - 24.0%; A2 - 11 people with I-III stages of HIV infection, men 72,7%, women - 27,3%; A3 - 35 HIV infected with stage IV disease, men 76.0%, women - 24.0%. All patients had an increase in intoxication indices and sex-dependent changes. Nonspecific reactivity indices in group A1 were above the norm, independent of gender except the index of neutrophils and lymphocyte (NLR). Below the norm is the immunoreactivity index (IR), the lymphocyte-monocyte ratio index (LMR), the lymphocyte index (Ilymph), the index of allergization (IA). Indices of nonspecific reactivity of A2 patients exceeded the norm and were independent of sex, with the exception of IR, Ilymph, IA, which were reduced. Non-specific reactivity indices are increased in HIV-infected group A3. Below the norm were IR, LMR, Ilymph, IA. Analyzing the activity indexes of inflammation, it became clear that the Krebs index (KI) was increased in all groups of patients; lymphocyte-granulocyte index (ILG) in groups A1 and A3 is less than normal, unlike patients in group A2, where it remained within the normal range. The leukocyte ratio and erythrocyte sedimentation rate (ILESR) in A1 and A3 have increased rates, unlike in A2, where the index is smaller. Conclusions: Men are predominantly HIV positive. The systemic immune response is more pronounced in women. There is a progressive impairment of immunological reactivity, indicating an immunodeficiency of the cell type with a decrease in nonspecific anti-infective protection. Patients with stage IV of HIV infection have moderate and severe inflammatory reactions, impaired reactivity, and are more pronounced in women.

The effects of favipiravir on hematological parameters of covıd-19 patients.

This study aims to evaluate changes in hematological parameters after the follow-up of patients who received treatment with favipiravir due to COVID-19 infections. Sixty-two cases receiving favipiravir treatment for at least five days due to COVID-19 infection were evaluated retrospectively. Parameters including age, gender, nasopharyngeal swab positivity, and chronic diseases were analyzed. Hematologic parameters were analyzed before and after the treatment. The mean age of the patients receiving treatment with favipiravir was 63.7±12.3 years. Nasopharyngeal swab positivity was detected in 67.7%. The most common comorbid conditions detected in patients were hypertension in 25 cases (40.3%) and diabetes in 16 cases (25.8%). In the statistical analysis of the hematological parameters before and after treatment with favipiravir, WBC, PT-PTT-INR levels were found to be unaffected; the mean RBC was found to have decreased from 4.33 ± 0.58 M/uL to 4.16 ± 0.54 M/uL (p:0.003); the median hemoglobin level was found to have decreased from 12.3 g/dl to 11.9 g/dl (p:0.041); the hematocrit level decreased from 38.1% ± 4.8 to 36.9% ± 4.2 (p:0.026); the median neutrophil count decreased from 4.57 K/uL to 3.85 K/uL (p:0.001); the mean lymphocyte count increased from 1.22 ± 0.53 K/uL to 1.84 ± 1.19 K/uL (p:0.000); and the mean platelet count increased from 244.1 ± 85.1 K/uL to 281.9 ± 103.3 K/uL (p:0.005). We concluded that the pathological effect of treatment with favipiravir on the hematologic system was the suppression in the erythrocyte series, and there were no adverse effects in other hematologic parameters.

Haematological outcomes in progression of malaria: A cohort study from district Dera Ismail Khan, Pakistan.

Malaria is the second highest reported disease from public health sector which affects about 4 million people each year in Pakistan. The study sought to evaluate the haematological changes in malarial patients in order to find any relation of these changes with malarial pathogenesis. This cross sectional descriptive study was designed at the pathology department of Gomal Medical College, Dera Ismail Khan during March 2015 to February 2017. Blood samples were collected from 400 malaria microscopy positive in EDTA tubes for the analysis of haematological parameters like Total leucocyte count, Haemoglobin, Platelets, Mean Cell Volume, Mean Cell Haemoglobin and Mean Cell Haemoglobin Concentration. Out of the 400 cases of malaria, 366 (91.5%) were Plasmodium vivax, 24 (6.0%) were Plasmodium falciparum and 10 (2.5%) were co-infection of Plasmodium vivax and Plasmodium falciparum infection. Anaemia was seen in 148 (37%) of cases; thrombocytopenia was 316(79%) and 60 (15%) cases had leucopenia. This study shows that malarial patients exhibited important changes in haematological parameters like thrombocytopenia; anaemia and leucopenia are significant predictors of malaria infection. When used in combination with other clinical and microscopy methods, these parameters could improve the diagnosis and treatment of malaria.

Single-blind placebo-controlled clinical study to evaluate the efficacy of Sida cordifolia Linn. in treatment of semen disorders (Sukra Kshaya) using semen and hormonal analysis

Background: Sida cordifolia Linn. is a well-known medicinal plant which exhibits anti-inflammatory, antioxidant, and sexual properties. It shows good promise in the treatment of male sexual disorders during its pre-clinical studies. Objective: The objective of the study was to assess the spermatogenesis action of aqueous extract of roots of S. cordifolia Linn. in clinical trials. Materials and Methods: The study uses qualitative criteria such as primary and secondary symptoms, and quantitative investigations such as hematological investigations, hormonal analysis, and semen analysis for assessing the therapeutic efficacy of research formulation through placebo-controlled clinical trials on 50 males having lack of sexual desire and non-satisfactory sexual life. Results: Very high inhibition was noticed in respect of primary symptoms such as lack of libido, difficulty in ejaculation or little amount of semen, as well as secondary symptoms such as nausea, body ache, headache, indigestion, loss of appetite, and general weakness in the research group. Lack of any adverse changes in hematological parameters (blood sugar, hemoglobin, ESR, RBC, and WBC) and biochemical parameters (bilirubin, protein, SGPT, SGOT, and ALP) indicates the non-toxic nature of research formulation. The hormonal levels registered a significant increase during the clinical study in research group, especially the testosterone level (8.53%). Semen quality evaluated through sperm count, motility, and morphology showed a significant improvement in research group, suggesting that administration of research drug in cases of stress-related sexual problems protected healthy cells by reduced generation of ROS and helped maintain quality parameters of spermatozoa during spermatogenesis. Conclusion: The research formulation made from roots of S. cordifolia Linn. shows good and significant (P < 0.05) therapeutic efficacy through inhibition of primary and secondary symptoms and enhancement in hormonal and seminal parameters, validating its spermatogenesis effect without any toxic or adverse effects.

Age-related changes in haematological parameters and biochemical markers of healing in the stomach of rats with acetic acid induced injury

This study examined the changes in haematological and biochemical variables in response to gastric mucosa injury in male Wistar rats divided into four groups according to their ages (3, 6, 12, and 18 months). 0.2 ml of acetic acid was injected intraluminal into the stomach glandular portion of each rat for 45 seconds under anaesthesia. Collection of blood and stomach samples occurred on days 3, 7, 14 and 21 post-induction of gastric ulcer. The results obtained from this study showed 100 % area of gastric mucosa healed in 3-month old rats, 91.72 %, 68.52 % and 62.81 % area of mucosa treated in 6, 12 and 18-month old rats respectively on day 21 post-induction of gastric ulcer. Increased circulation of blood cells in younger rats occurred, neutrophil-lymphocyte ratio (NLR) was decreased in younger rats (3 and 6 months) significantly (p < 0.05) when compared to older rats (12 and 18 months). Lipid peroxidation and glutathione (GSH) levels were elevated in older rats (12 and 18 months) significantly (p < 0.05) when compared to younger rats (3 and 6 months). In comparison, superoxide dismutase (SOD) and catalase levels were decreased in older rats (12 and 18 months) significantly (p < 0.05) when compared to younger rats (3 and 6 months). Histological evaluation showed evidence of early healing with re-epithelialisation and angiogenesis in younger rats, but older rats showed delayed healing. The study showed that the slower rate of healing of gastric ulcer with advancing age in rats might be due to reducing circulating blood cells and anti-inflammatory activities during healing via a lipid peroxidation-dependent mechanism.

Awareness Among College Students on the Changes in Hematological Parameters Due to COVID-19

Introduction: COVID-19 pandemic is caused by the coronavirus which belongs to the family of retroviruses virus It was first identified in the Wuhan province of China The origin of the virus is unknown so as the treatment for it, as there is no vaccine found till today Most of the people who are infected with the COVID-19 virus will experience mild to moderate respiratory illness and recover without requiring special treatment Older people and people with medical problems like cardiovascular disease, diabetes, chronic respiratory disease, and cancer are more likely to develop a serious illness which may lead to the death of the individual Till today there is no vaccine discovered hematological parameters are the constituents present in blood that constitutes the composition of blood such as red (RBC) and white blood cell (WBC) counts and hemoglobin (Hb) concentration are tightly regulated traits with high clinical relevance Values outside normal ranges are diagnostic for disorders, including cancer, immune diseases, and cardiovascular disease The COVID virus also affects these hematological parameters in a significant way The only preventive way is social isolation Aim: The main of the survey is to create awareness among college students on the various changes in hematological parameters during COVID-19 Materials and Methods: A questionnaire was prepared and administered to a hundred participants through Google forms an online platform These study participants included college students of Saveetha dental college Result and Discussion: The overall result was positive as most of the study population were aware of the change in the hematological parameters due to COVID-19 This proves an outright positive result Conclusion: The study was conducted to analyze the awareness of the hematological changes caused due to COVID-19 virus among the college students © IJCRR

HEMATOLOGICAL CHANGES AFTER INTRODUCTION OF DIFFERENT SIZES LEAD NANOPARTICLES (IN EXPERIMENT)

The aim: Was to compare the changes in hematological parameters of blood in the conditions of prolonged exposure of lead sulfide nanoparticles (NP) of different sizes and of lead nitrate. Materials and methods: The study was conducted on mature male Wistar rats 160-180 g, intraperitoneally injected with Pb(NO3)2 and NP PbS of 26-34 nm and 50-80 nm in 0,94 mg/kg/day dose adjusted to lead. Toxic effects were evaluated after 1,5 months, 3 months and 1 month after exposure. The studies were performed on hematologic analyzer. Results: Changes in peripheral blood were characterized by decrease in the hemoglobin level in the blood. An increase in the total number of leucocytes was observed, which is statistically significant by the increase of number of lymphocytes and the absolute number of monocytes. Changes in the platelet number were characterized by an increase in the average volume of platelets and a decrease in the platelet heterogeneity index. Conclusions: The most pronounced changes hemoglobin level in the blood and concentration of hemoglobin in the erythrocyte were observed in the effects of PbS NP (50-80 nm), but leucocytes indicators - of PbS NP (26-34 nm) and Pb(NO3)2.
