Withania coagulans root powder effect on growth, hematology, digestive enzyme activity, antioxidant status, serum immune response, and tolerance against Aeromonas hydrophila in Common Carp

AbstractObjectiveThe use of plant‐derived products in aquaculture has garnered considerable attention due to their potential benefits. This study investigated the impact of supplementing Withania coagulans root powder (WCRP) in the diet of Common Carp Cyprinus carpio on various parameters, including growth performance, digestive enzymes, hematology, antioxidant activity, and immunological aspects.MethodsCommon Carp (mean weight ± standard deviation = 11.69 ± 0.48 g) were divided into four groups in triplicate, receiving different WCRP concentrations (0.0, 1.0, 1.5, and 2.0%; labeled as WCRP0, WCRP1.0, WCRP1.5, and WCRP2.0, respectively) over a 60‐day period, followed by an experimental challenge with Aeromonas hydrophila to assess the relative percentage survival (RPS) over 14 days.ResultResults showed that Common Carp receiving WCRP1.5 and WCRP2.0 demonstrated significantly improved growth performance, with reduced feed conversion ratios (FCRs) being particularly evident in WCRP1.5. Polynomial contrasts indicated significant linear and quadratic effects on weight gain and FCR. Additionally, WCRP1.5 and WCRP2.0 supplementation led to significantly higher activity of digestive enzymes (lipase and protease). Hematological parameters, including white blood cells, red blood cells, hemoglobin, and hematocrit, were significantly elevated in fish that were fed WCRP1.5 and WCRP2.0 compared to the control group. Moreover, serum parameters, such as total protein, albumin, globulin, lysozyme, catalase, superoxide dismutase, and total immunoglobulins, were significantly enhanced in WCRP1.5‐ and WCRP2.0‐treated fish. Notably, the WCRP1.5 group showed the lowest serum cortisol levels. The RPS was highest in WCRP1.5 (73.77%), followed by WCRP2.0 (70.43%), compared to the other groups.ConclusionIn conclusion, supplementation with WCRP1.5 and WCRP2.0 effectively improved both growth and health parameters in Common Carp.

Impact of varying sorbitol concentrations on hematological and biochemical blood parameters in Wistar rats (Rattus norvegicus)

Background: Sorbitol is an artificial sweetener that is very similar to natural sugar, but it is sweeter than natural sugar and lower in calories. Sorbitol is used as an alternative to natural sugar, and it is extracted from regular glucose. It does not have any negative effects on the animals’ health, and it is characterized in safe use in many scientific experiments for the diet of humans and animals.Methods: This study was conducted in the animal house, College of Veterinary Medicine, Al-Qasim Green University for a period of 90 days. Forty rats of the Wistar strain (Rattus norvegicus) were randomly distributed into 4 groups, namely the first group (control group) while the second, third and fourth groups were treated with 100, 200 and 300 μg of sorbitol/kg of body weight .The rats were iso in live weight and age at the beginning of the experiment. Blood samples were drawn at the end of the experimental period. Results: Increase in level dose of sorbitol resulted significant improvement in accounts of red blood cells, white blood cells, and a significant increase in level of hemoglobin, lymphocytes, and monocytes for second, third, and fourth groups compared to the control group. Moreover, the significant improvement in most of the blood parameters was reflected to significant increase in clotting and bleeding time in the second, third and fourth groups of rats compared to the control group. Also, the results showed a significant increase in the levels of FSH, LH, testosterone, Inhibin and MAD hormones for the second, third and fourth groups compared to the control group.Conclusions: The results of the current study revealed that sorbitol has many benefits in the diet of humans and animals and has an effect on blood indicators, some sex hormones and antioxidants in the body. It is recommended not to consume excessive sorbitol in the diet.Keywords: Sorbitol; Hematological parameters; FSH; LH; Wistar rats

A systematic review of lithium biology and pharmacology and toxicological evaluation of new organic lithium salts

Objective: to systematize scientific data on biomedical studies investigating trace element lithium over the past 70 years; evaluate toxic properties of lithium ascorbate (LiAsc) as an important promising candidate molecule.Material and methods. An analysis of 49,959 publications on lithium biomedical research retrieved from PubMed/MEDLINE database was carried out using modern data mining methods developed within the framework of topological approach to recognizing (Yu.I. Zhuravlev scientific school). Publications found by experts and not indexed in PubMed/MEDLINE were used in discussing the results of a systematic analysis of publications array retrieved from PubMed/MEDLINE. An experimental study of chronic 180 day-long LiAsc (at doses of 5, 50 and 150 mg/kg) toxicity was performed on 36 “Soviet chinchilla” rabbits by assessing local irritant action. Intoxication clinical picture, body weight dynamics, water and food intake as well as physiological, hematological and biochemical parameters were analyzed.Results. Classification and systematization of all currently available publications on lithium biology and medicine were performed. It was shown that pharmacological applications of lithium salts in mental disorders as well as lithium effects on simple sugars metabolism, lipid metabolism, blood pressure regulation, hematopoiesis, inflammation and tumor growth inhibition, neurotransmitter homeostasis, neurotrophic and neuroprotective molecular mechanisms as well as homeostasis of other electrolytes comprised promising fields of lithium drug research. The prospects for using organic lithium salts, particularly LiAsc, for various therapeutic goals were also discussed. 180-day-long oral administration of LiAsc at doses of 5, 50, 150 mg/kg resulted in no macroscopic signs of local inflammatory reaction while examining its local irritant effect.Conclusion. The lithium-ion effect on neurotransmitters promotes neuroprotection and reduces a risk of addiction. The antihypertensive, antiatherosclerotic, antidiabetic, antitumor and neurotrophic effects related to organic lithium salts may be beneficial in various therapeutic applications.

Impact of varying levels of soy hulls and β-mannanase enzyme supplementation on growth performance, carcass characteristics, nutrient utilization and blood biochemical profile in broiler chickens

Two hundred and forty day-old broilers were randomly assigned to six experimental groups in a 2 x 3 factorial design. The birds were fed diets containing soybean hulls (SH) at the levels of 4% and 6% and β-Mannanase (BM) at the concentration of 0%, 0.05% and 0.1%. Results indicated significant effects of SH and BM supplementation on body weight (BW) and weight gain (WG), with birds fed 4% SH and 0.1% BM exhibiting higher (p < 0.05) body weight and weight gain compared to other groups. Feed conversion ratio (FCR) was improved (p < 0.05) in birds receiving 4% SH with 0.1% BM supplementation. However, no significant effects were observed on carcase traits across treatment groups. Regarding nutrient digestibility, birds supplemented with 0.1% BM showed improved (p < 0.05) crude protein (CP) digestibility compared to those without BM supplementation. No significant variations were observed in dry matter, crude fibre and ether extract utilisation among treatment groups. Hematological and serum biochemical parameters were not influenced by SH and BM supplementation, indicating no adverse effects on blood parameters. In conclusion, these findings underscore the potential advantages of incorporating 4% SH and 0.1% BM in broiler diets for enhanced growth performance and nutrient utilisation.

The influence of probiotics bacteria Lactobacillus acidophilus improves the survival, growth, and Hematological performance of the Indian major carp Rohu (Labeo rohita). After acclimation, a 60-day experimental study was conducted with four different types of treatments; namely, T1: Control, i.e. Basal feed without Probiotic supplements, T2: Basal feed with Aeromonas hydrophila, T3: Lactobacillus supplemented probiotic feed without Aeromonas hydrophila, and T4: Lactobacillus supplemented probiotic feed with A. hydrophila. After the experimental study, growth parameters were monitored through Weight gain, Specific growth rates, survival percentage, and haematological parameters including WBC, RBC, haemoglobin (Hb), and haematocrit (Hct) values of probiotics treated group (T3 and T4) were significantly (P&lt;0.05) higher than control and T2 group. The Present study indicated that the positive effects of the L. acidophilus probiotic supplement diet improved the survival, growth, and Haematological performance in aquaculture.

Does Occupational Exposure to Chemicals/Carcinogens Affect the Hematological Parameters of Workers?

Background/Objectives: Chemical and carcinogenic risk in workplace are linked to an increase of the incidence of cancer in exposed workers. The aim of this observational study was to identify an association between exposure to chemical risk and changes in hematochemical parameters of workers exposed. Methods: The study examined blood count parameters performed on 4523 employees of Sapienza University of Rome from September 2019 to February 2020. A total of 1402 workers in research laboratories, exposed to chemical risk and carcinogens, was compared with a cohort of 3121 blood donors, in apparently good health, matched for age, sex, and period of blood collection. Results: Multivariate analysis demonstrated acrylamide is the most frequently associated chemical with significant changes between the groups. It is related to an increase in monocytes and MPV, a reduction of lymphocytes, platelets, and red series values, while MCH remained unchanged. Formaldehyde reveals the same changes as acrylamide, with the exception of the percentage of lymphocytes, red blood cells, and HB, which remain unchanged. Other chemicals and carcinogens show variations for few blood count parameters. Conclusions: The present study found out a significant change in blood count values in workers exposed to acrylamide and formaldehyde. It also showed an increase in the mean monocyte value in employees exposed to carcinogenic risk, compared to non-exposed, with the exception of Trypan Blue. The implementation of efficient health surveillance remains of critical importance. These data should be compared with those from follow-up studies.

Microbiological and Haemato-biochemical Studies in Canine Pyometra

Background: Canine pyometra, is a pathological condition that results in the accumulation of purulent exudate in the uterus due to hormonal imbalance in female dogs. This is the most prevalent hormonally mediated reproductive disorder and life threatening disease of intact female dogs. The objective of the present study was to assess the physiological, haematological and biochemical changes and isolate the pathogenic microorganism present in the uterus of pyometra bitches. Methods: This study was carried out in ten bitches with a history of lethargy, depression, in appetence, polydipsia, occasional vomiting and vaginal discharge presented for treatment at the Veterinary Poly Clinic, Coimbatore, Tamil Nadu. The disease was diagnosed by history, clinical signs, physical examination, imaging techniques haematology and biochemical study. The involvement of the pathogenic organism was confirmed by microbial examination of the pus-filled uterus after the ovariohysterectomy. Result: The result showed that physiological parameters rectal temperature, heart rate and respiration rate were increased in pyometra affected dog than healthy one. The haematological parameters of red blood cell count, haemoglobin and packed cell volume were decreased in pyometra affected dogs than healthy dogs. Leukocytosis, neutrophilia, lymphocytosis, monocytosis and eosinophilia condition also observed in pyometra affected dogs. Biochemically, increased Blood urea nitrogen (BUN) creatinine and hyperprotenimia were observed in pyometra dogs. Increased activity of hepatic enzyme Alanine transaminase (ALT), Aspartate aminotransferase (AST) and Alkaline phosphatase (ALP) were also observed in pyometra dogs. The major pathogenic microorganisms involved in pyometra are Escherichia coli (40.25%), Staphylococcus (20.46%), Streptococcus (20.32%), Pseudomonas (6.41%), Proteus (6.32%) and Pasteurella (6.24%). Thus the dogs with pyometra show significant changes in physiological, haematological, biochemical parameters and growth of pathogenic microorganism in uterine fluid were the important indications of pyometra affected dogs.

Hematologic Parameters Cut-off Assessment of Adult Alpha-Thalassemia Patients in Iran

Background: Thalassemia is one of the most common blood disorders in Iran. Alpha-thalassemia is caused by the deletion of the alpha-globin gene. The frequency of deletions in the alpha-globin gene is associated with microcytosis and hypochromia, making hematological parameters valuable predictive tools in the initial identification of alpha-thalassemia patients. This study aimed to compare hematologic parameters such as Mean Corpuscular Volume (MCV), Mean Corpuscular Hemoglobin (MCH), red blood cell (RBC) count, and hemoglobin (HGB) levels in silent and minor patients, whose genotypes were genetically characterized, with normal patients to establish cut-off points for these groups. Materials and Methods: The study involved a total of 860 patients with alpha-thalassemia, including 267 cases of silent, 261 cases of minor, and 332 cases of normal alpha-thalassemia. Results: Analysis of blood indices based on sex revealed that the male group had higher values than the female group. Assessment of alpha-thalassemia in minor patients showed that the Cis form (—/αα) had higher microcytosis than the Trans form (–α/–α) in this group. This difference was also observed between α-3.7α/ α-3.7α and (αα)-MED/αα as two different genetic forms in minor patients, with (αα)-MED/αα being in the Cis form. Data indicated that the cut-off value was insignificant in silent patients compared to the normal group. However, minor patients with MCH≤23.7 and MCV≤74.9 had an AUC greater than 0.9 (p-value&lt; 0.01), distinguishing them from the normal group. Conclusion: Comparing hematological parameters in these groups illustrated that MCV and MCH are the best predictor parameters for distinguishing between groups.

Immunological, Serological and Hematological Changes in COVID 19 Patients of Dhaka City

The analytical test reports of COVID-19 patients admitted in two major hospitals in Dhaka City were analyzed to observe the immunological, serological and hematological abnormalities that can be significant for managing the patients in emergencies. The observed levels of ferritin, procalcitonin, D–Dimer, C-reactive protein (CRP), creatinine and alkaline phosphatase (Alkp) were taken into consideration for this study. Though these parameters were elevated as mentioned for patients from many other countries, in significant cases, the values were normal or even lower than the normal levels. The ferritin level was normal (For men, 24 to 336 micrograms per liter. For women, 11 to 307 micrograms per liter) in only 30% of the patients, whereas, 50% of the patients had higher values and 20% patients had the lower values. Similarly, the procalcitonin (normal value 0.1 to 0.5 ng/mL) level was found to be normal in only 27% of the patients while remaining 73% patients had the high level of this parameter. The D‑Dimer level (less than 0.50) was also found to be normal in only 27% of the patients, whereas 72% of the patients had the higher levels. The C‑reactive protein was within the normal level in only 22% of the patients, whereas, 76% of the patients had the high level of this marker. The creatinine was found to be increased in 60% of the patients. There were 88% patents having increased levels of Alkp with only 12% patients having normal levels. Thus, the elevations of the immunological, serological and hematological parameters were somehow different from those observed from patients in other countries. This information might be useful in managing the hospitalized COVID-19 patients in our country. Jagannath University Journal of Science, Volume 11, Number 1, June 2024, pp. 203−207

Development of a Therapeutic Agent Based on Escherichia coli, Assessment of Harmlessness and Anti-Radiation Activity

The paper presents the development, assessment of the safety and antiradiation activity of a therapeutic agent based on the culture of Escherichia coli strains “PL-6” and “KV-1”. To obtain the antiradiation agent, the causative agent of colibacillosis was grown in meat-peptone broth in a thermostat at a temperature of 37°C for 3 days. The grown suspension was centrifuged at 3000 rpm for 50 min, the supernatant was decanted. The sediment was brought to 1 billion cm3 with distilled water. Smears were prepared from the grown cultures and stained according to Gram to determine the purity and species of the grown culture. The prepared suspension was poured into sterile vials of 10, 50 or 100 cm3, sealed with rubber stoppers and rolled with aluminum caps, labeling with an indication of the strain, radiation dose and date. Irradiation of the microbial material was carried out on the γ-installation “Issledovatel”, source 60Co, absorbed dose rate of 1.028 Gy/sec, in the ranges of absorbed doses from 7.5 to 30.0 kGy with interdose intervals of 2.5 and 5.0 kGy. The degree of inactivation of γ-irradiated E. coli cultures was determined by seeding them on meat-peptone agar and thermostatting for 168 hours, recording the presence or absence of microorganism growth. The studies have established that the timing and degree of growth of irradiated E. coli cultures of the “PL-6” and “KV-1” strains are directly dependent on the radiation dose, their complete inactivation occurs with irradiation at a dose of 25.0 kGy. Further studies have shown that the developed biopreparation obtained on the basis of E. coli is sterile, areactogenic, non-toxic and harmless. The mechanism of formation of radioresistance of the organism against the background of application of antiradiation agents based on E. coli strains “PL-6” and “KV-1” consisted in restoration of hematological, biochemical and immune parameters, which contributed to preservation of 66.7 to 83.3٪ of lethally irradiated animals.

Toxicity effects of hexavalent chromium on hematological, biochemical and digestive enzyme profiles of Labeo rohita (Hamilton, 1822).

The study provides a descriptive understanding of the toxic effect of heavy metal chromium on the hematological, biochemical, and digestive enzyme profiles in the fingerlings of Labeo rohita. The 96-h LC50 of hexavalent chromium was found to be 15.76 mg/L. Further, the toxicity study was conducted with four different sub-lethal concentrations of 96-h LC50 viz. 1/40th, 1/20th, 1/10th, and 1/5th respectively. The blood samples from the control and treated groups exposed to different concentrations were examined for various physiological parameters. The obtained data showed that, with the increase in sub-lethal concentration, a significant decrease (p < 0.05) in red blood cell (RBCs), hemoglobin (Hb), and hematocrit (Hct) was observed, while total white blood cell (WBCs), mean corpuscular volume (MCV), and mean corpuscular hemoglobin (MCH) increased significantly (p < 0.05) in all the treatments. Fishes exposed to chromium for 30 days responded by becoming hyperglycemic, hyperproteineric, and hypoalbuminemia with a gradual rise in concentrations. Alteration in the intestinal digestive enzyme profiles was also observed after 30 days of study. The activity of protease (89.76%), and amylase (41.88%) decreased in the intestine with the highest concentration compared to the control. Conversely, compared to the control, the highest concentration resulted in an increase (146%) in lipase activity. Overall, this study has greatly enhanced our comprehension of the impact of chromium toxicity on various hematological, biochemical, and digestive enzyme parameters in Labeo rohita.

Effectiveness of biologically active substances added to sturgeon feeds

The purpose of this research was to study the effect of the vitamin‐mineral complex E‐selenium and the probiotic preparation Bacell when added to industrial feed on the fish‐breeding‐biological and physiological‐ biochemical parameters of juvenile sterlet‐beluga hybrids when reared in cages.The duration of the experiment was 45 days. In experimental option 1, the fish were fed with basic compound feed with the addition of E‐selenium (300 μg selenium/kg of feed), in experimental option 2, the fish were fed with basic compound feed with the addition of E‐selenium (300 μg selenium/kg of feed) and the Bacell preparation (0.2 % by weight of dry food). The control variant was fed with basic feed.The absolute increase in the experimental variants was 13.0–25.0 % higher than in the control. Hematological parameters varied – in some cases with a high degree of significance. In particular, hemoglobin increased by 5.6–13 %, blood serum protein by 0.42–12.6 %, cholesterol by 9.8–16.3 % in the experimental variants and by 70.5 % in the control, due to the presence of a high degree of stress in control fish. At the same time, in fish experiments the effects of stress factors were suppressed by antioxidants. Preventive doses of microelements, vitamins and probiotics reduce and stabilise peroxide processes and contribute to the maintenance of good physiological condition of fish kept in artificial conditions.

Machine learning algorithm approach to complete blood count can be used as early predictor of COVID-19 outcome.

Although the SARS-CoV-2 infection has established risk groups, identifying biomarkers for disease outcomes is still crucial to stratify patient risk and enhance clinical management. Optimal efficacy of COVID-19 antiviral medications relies on early administration within the initial five days of symptoms, assisting high-risk patients in avoiding hospitalization and improving survival chances. The complete blood count can be an efficient and affordable option to find biomarkers that predict the COVID-19 prognosis due to infection-induced alterations in various blood parameters. This study aimed to associate hematological parameters with different COVID-19 clinical forms and utilize them as disease outcome predictors. We performed a complete blood count in blood samples from 297 individuals with COVID-19 from Belo Horizonte, Brazil. Statistical analysis, as well as ROC Curves and machine learning Decision Tree algorithms were used to identify correlations, and their accuracy, between blood parameters and disease severity. In the initial four days of infection, traditional hematological COVID-19 alterations, such as lymphopenia, were not yet apparent. However, the monocyte percentage and granulocyte-to-lymphocyte ratio proved to be reliable predictors for hospitalization, even in cases where patients exhibited mild symptoms that later progressed to hospitalization. Thus, our findings demonstrate that COVID-19 patients with monocyte percentages lower than 7.7% and a granulocyte-to-lymphocyte ratio higher than 8.75 are assigned to the hospitalized group with a precision of 86%. This suggests that these variables can serve as important biomarkers in predicting disease outcomes and could be used to differentiate patients at hospital admission for managing therapeutic interventions, including early antiviral administration. Moreover, they are simple parameters that can be useful in minimally equipped health care units.

Evaluation of Some Hematological Parameters for Patients Infected with Entamoeba Histolytica in Najaf Governorate

General background: Amoebic dysentery caused by Entamoeba histolytica is a significant public health concern, particularly in regions with poor sanitation. It can lead to various complications, including changes in blood parameters. Specific background: Identifying changes in blood indicators during amoebic infections can aid early diagnosis and improve patient outcomes. Knowledge gap: There is limited research exploring gender-based differences in blood parameters of patients with amoebiasis. Aims: This study aimed to evaluate the effect of E. histolytica infection on specific blood parameters in male and female patients and to assess gender-based variations in these parameters. Results: A total of 45 patients (20 males, 25 females) diagnosed with amoebiasis were included, with samples collected between May 2023 and January 2024. Significant differences (P ≤ 0.05) were observed between male and female patients in RBC, HB, HCT, and MCH, while no significant differences were noted for MCV, MCHC, RDW, PLT, WBC, or LYM. Male patients showed higher mean values of RBC (5.01 ± 0.65) and HB (14.6 ± 1.61) compared to females (RBC: 4.5 ± 0.54; HB: 12.28 ± 1.24). Novelty: This study highlights gender-specific alterations in blood parameters during amoebiasis, providing new insights into how gender affects physiological responses to E. histolytica infection. Implications: Regular monitoring of blood parameters, particularly RBC and HB, in patients with amoebiasis is crucial for early diagnosis and treatment. The findings also underscore the importance of gender considerations in clinical management and suggest the need for larger studies to confirm these results and explore their diagnostic and therapeutic implications. Highlights: Gender impacts blood parameters in amoebiasis patients. Males show higher RBC and HB than females. Regular monitoring aids early E. histolytica diagnosis. Keywords: Amoebic dysentery, Entamoeba histolytica, blood parameters, gender differences, early diagnosis

Preoperative Delta Neutrophil Index, Platelet Lymphocyte Ratio and Immature Granulocyte Count for Differentiating Metastatic Colon Cancer from Non-Metastatic Colon Cancer: A Retrospective Study.

Immature granulocytes show bone marrow activation before neutrophil response and there are studies in the literature showing that the number of immature granulocytes is an auxiliary marker in the diagnosis and treatment of different diseases. The Delta Neutrophil Index (DNI), Immature Granulocyte Count (IGC) have previously been studied as markers in thyroid and breast cancers. The aim of this study was to determine whether immature granulocyte IGC and DNI values measured in preoperative blood parameters have a diagnostic benefit for the detection of advanced colon cancer. A study was conducted on patients who had undergone selective operation for colon cancer in our clinic from February 2015 to February 2020. The patients were divided into two groups: early stage (stage I-III) and advanced stage (stage IV) colon cancer. The IGC and DNI values as well as other hematological parameters, demographic parameters (sex, age) in these two groups were compared. A total of 43 patients with mean age 67.47 (35-96) years were included in the study. Eighteen of the patients were male and 25 were female. When the early stage and advanced stage colon cancer groups were compared, no statistically significant difference was found between age, sex, white blood cell count, lymphocyte-to-monocyte ratio, eosinophil count, basophil count, mean platelet volume and: systemic immune-inflammation index score. It was observed that platelet-to-lymphocyte ratio, IGC and DNI or Immature Granulocyte Percentage (IGP) values were statistically significantly higher in the metastatic colon cancer group compared to the non-metastatic group. When the specificity and sensitivity of laboratory markers in metastatic colon cancer were examined, it was observed that the specificity and sensitivity of DNI or IGP and IGC were statistically higher than other values. DNI, IGC and PLR values, which are the parameters measured in the preoperative period are easily measurable laboratory parameters and do not involve additional costs in differentiating metastatic from non-metastatic colon cancer in the preoperative period.

Role of Innate Lymphoid Cells on Laboratory Mice Routine Handling Process and their Effect on the Other Immunological Parameters

Introduction: Lab mice typically belong to the Mus musculus species. They are the prevailing choice for mammalian research and are utilized for studies in genetics, physiology, psychology, medicine, and various scientific fields. Aim of the study: The current research aimed to examine how frequently handling laboratory mice impacts their innate immune response through innate lymphoid cells, mucus secretion, as well as various physiological and biochemical blood parameters, and its potential implications on research outcomes. Study design: Sixty female mice were used in this study all animals were hosted under the same condition and treated with the same rotational animal handling process in different periods including animal control oral gavage and intraperitoneal, sub courteous, and intramuscular injection. Blood samples were gathered at four different time points to analyze various hematological and biochemical parameters, including (RBC, Hb, PCV, WBC, ALT, AST enzymes, and urea levels, etc.) while colon tissue were collected and the immunohistochemistry and PAS staining were preformed to evaluate the innate lymphoid cells and mucin secretion at three level through the experimental period. The results: Based on the findings, there were no notable variations in the levels of Hb and RBC. However, there was a noticeable increase in the WBC count for all animals after 4 minutes of handling, and the levels began to normalize after 10 and 30 minutes. As for the blood's biochemical parameters, including ALT, AST, creatinine, and urea, no details were provided. The results showed that there were no noteworthy alterations in these parameters throughout the entire experimental period. Conclusion: The handling of the animals is one of the most important factors that can influence the experimental results in lab mice. The WBCs and samples should be collected at least 30 minutes after the handling procedure.

Anti irradiation nanoparticles shelter immune organ from radio-damage via preventing the IKK/IκB/NF-κB activation

BackgroundNormal tissue and immune organ protection are critical parts of the tumor radiation therapy process. Radiation-induced immune organ damage (RIOD) causes several side reactions by increasing oxidative stress and inflammatory responses, resulting in unsatisfactory curability in tumor radiation therapy. The aim of this study was to develop a novel and efficient anti irradiation nanoparticle and explore its mechanism of protecting splenic tissue from radiation in mice.MethodsNanoparticles of triphenylphosphine cation NIT radicals (NPs-TPP-NIT) were prepared and used to protect the spleens of mice irradiated with X-rays. Splenic tissue histopathology and hematological parameters were investigated to evaluate the protective effect of NPs-TPP-NIT against X-ray radiation. Proteomics was used to identify differentially expressed proteins related to inflammatory factor regulation. In addition, in vitro and in vivo experiments were performed to assess the impact of NPs-TPP-NIT on radiation therapy.ResultsNPs-TPP-NIT increased superoxide dismutase, catalase, and glutathione peroxidase activity and decreased malondialdehyde levels and reactive oxygen species generation in the spleens of mice after exposure to 6.0 Gy X-ray radiation. Moreover, NPs-TPP-NIT inhibited cell apoptosis, blocked the activation of cleaved cysteine aspartic acid–specific protease/proteinase, upregulated the expression of Bcl-2, and downregulated that of Bax. We confirmed that NPs-TPP-NIT prevented the IKK/IκB/NF-κB activation induced by ionizing radiation, thereby alleviating radiation-induced splenic inflammatory damage. In addition, when used during radiotherapy for tumors in mice, NPs-TPP-NIT exhibited no significant toxicity and conferred no significant tumor protective effects.ConclusionsNPs-TPP-NIT prevented activation of IKK/IκB/NF-κB signaling, reduced secretion of pro-inflammatory factors, and promoted production of anti-inflammatory factors in the spleen, which exhibited radiation-induced damage repair capability without diminishing the therapeutic effect of radiation therapy. It suggests that NPs-TPP-NIT serve as a potential radioprotective drug to shelter immune organs from radiation-induced damage.

Effects of pH Variations on Growth and Haematological Parameters of Pangasianodon hypophthalmus (Sauvage, 1878)

An experiment was carried out with an aim of enhancing culture of Pangasianodon hypophthalmus. Juveniles with an average length of 13.35±0.14 cm and 17.52±0.16 g of body weight were subjected to various pH levels of 7.5 (Control), 6, 9 and 9.5 to determine their growth and hematological changes. The control group exhibited the highest growth in both length (14.70±1.04 cm) and weight (21.12±2.67 g), while the lowest length (13.87 ± 0.43 cm) and weight (18.92 ± 1.11 g) in pH 9.5. The highest (1.24 ± 0.15) and lowest (0.56 ± 0.15) value of SGR was noticed in control and pH 9.5 respectively. The highest value of PER (3.79 ± 0.38) was observed in control and the lowest (1.66 ± 0.31) in pH 9.5. The highest (2.59 ± 0.47) and lowest (1.11 ± 0.16) value of FCR observed in pH 9.5 and control respectively. The highest count (26.80 ± 1.01 (103/µl)) of TLC was observed in pH 9.5 and the least (22.26 ± 0.53 (103/µl)) in control. The highest count (2.47 ± 0.15 (106/µl)) of TEC was observed in control and the least (1.97 ± 0.23 (106/µl)) in pH 9.5. The highest value (9.42 ± 0.14 g/dL) of Hb was observed in control and the least (9.5 with 5.77 ± 0.56 g/dL) in pH 9.5. The highest value (29.06 ± 0.46%) of Ht was observed in control and the least (22.41 ± 2.11%) in pH 9.5. The highest value (124.93 ± 9.99 fL) of MCV was observed in pH 9 and the lowest (114.45 ± 11.98 fL) in pH 9.5. The highest value (32.42 ± 0.76 g/dL) of MCHC was observed in control and the lowest (25.73 ± 0.87 g/dL) in the pH 9.5. The study revealed that P.hypophthalmus juveniles showed significant difference (p &lt; 0.05) between the control and treatments. Study inferred that alterations in the growth and haematological parameters were occurred at higher pH levels compared to lower pH levels.

AbstractObjectiveThis study investigated the effects of supplementing Nile Tilapia Oreochromis niloticus diets with wild olive Olea europaea leaf extract (WLE) on growth performance, digestive enzymes, and antioxidant and immunological parameters.MethodsWild olive leaf extract was added at different concentrations (WLE 0.0 [control], 1.0, 1.5, and 2.0%) and fed to triplicate fish groups for 12 weeks. At the end of the trial period, growth performance, body composition, digestive enzyme activities, and hematological, biochemical, antioxidant, and immunological parameters were evaluated.ResultAccording to the results, fish that were fed with WLE 1.5% and WLE 2.0% exhibited significantly improved weight gain, specific growth rate, and feed intake. The feed conversion ratio (FCR) was significantly reduced in fish supplied with WLE 1.5% and WLE 2.0%. Additionally, weight gain and FCR showed significance at both the linear and quadratic levels, as indicated by polynomial contrasts. However, the experimental diets did not impact fish body composition, digestive enzyme activity, or survival rate. Fish that received WLE 1.5% and WLE 2.0% showed significantly higher levels of white blood cells, red blood cells, hemoglobin, and hematocrit compared with the WLE 1.0% and control groups. Moreover, significant enhancements were observed in serum parameters, including total protein, albumin, globulin, lysozyme, catalase, superoxide dismutase, and total immunoglobulins, for the WLE 1.5% and WLE 2.0% groups compared with the control. Fish that were fed WLE 1.5% exhibited the lowest serum cortisol level.ConclusionIn conclusion, experimental diets with WLE levels of 1.5% and 2.0% effectively enhanced both the growth and immunological parameters of Nile Tilapia.

Dietary Chlorella vulgaris mitigates aflatoxin B1 toxicity in broiler chicken: Toxicopathological, hematobiochemical and immunological perspectives

Mycotoxins are the chemical substances, produced as the secondary metabolites of some toxigenic species of fungi which cause critical health issues in humans, birds and different animal species while Chlorella vulgaris (CV) is a unicellular microalga which contains plenty of important nutritional ingredients. This study was planned to evaluate the toxicopathological, hematobiochemical and immune changes incurred by dietary supplementation of aflatoxin B1 (AFB1) and their mitigation through CV in broilers. For this study to be conducted, 180 broiler birds of one day old were uniformly distributed into six (06) groups and administered various combinations of AFB1 (200 μg/kg) or CV (0.5 and 1.0%) and the duration of the experiment was 42 days. Parameters deliberated were body weight, feed intake, relative visceral organ weights, gross and histopathological examination, hematological parameters (erythrocytic and leukocytic count, hematocrit and hemoglobin), serum biochemical analysis (serum total proteins, ALT, globulin, albumin, creatinine and urea), humoral response against sheep RBCs, response to subcutaneous injection of phytohemagglutinin-P and phagocytic system function assay. The results of this experiment confirmed that 1.0% CV efficiently mitigated AFB1 induced alterations in the studied parameters while this mitigation was partial when 0.5% CV was used with AFB1. Further studies in this regard are still needed to investigate the exact AFB1:CV ratio responsible for complete amelioration.
