    Abstract Estrogens are a group of hormones that have diverse effects on both reproductive and non-reproductive organs. Conjugated estrogens are medicine that contains a mixture of estrogen hormones. The study was conducted to observe the effects of varying doses of conjugated estrogen on body weight, hormonal and histological alterations of reproductive organs in adult swiss albino female mice. In this study, 60 female swiss albino mice (Mus musculus) aged 28–30 days with an average body weight of 28.2 ± 1 g were used. At first, the mice were randomly divided into 4 groups each containing 15 mice. Group A was served as vehicle control and fed on standard mice pellet and fresh drinking water. While, groups B, C and D were administered with conjugated estrogen orally at the daily dose rate of 125 μg, 250 μg and 500 μg/kg body weight respectively with 1 mL sesame oil as a vehicle by mixing with feed. The experiment was carried out for 90 days. After humanly euthanized, blood was collected and serum was prepared and organs were collected for histopathology. The results revealed that higher doses of conjugated estrogen resulted in weight loss in premenopausal female mice compared to lower doses. Serum estrogen and thyroxine concentration was increased significantly following the doses of conjugated estrogen. Ovarian histotexture showed congested blood vessels and cystic space with degeneration of follicles and corpus luteum. Uterine lesions included massive macrophage infiltration in endometrium and hyperplasia of glandular epithelium at a lower dose; hyperplasia and hypertrophy of glandular epithelium (pleomorphism) with normal macrophage infiltration in endometrium at a higher dose. Therefore, it can be concluded that oral conjugated estrogen therapy at high dose has more detrimental impacts on body weight and reproductive function compared to lower dose in female adult mice.

    Abstract Objectives: The research aims to assess the impact of coral fossil (CF) on hematobiochemical parameters, organ’s accumulation, and remodulation in lead (Pb) intoxicated broiler birds. Methods: 45 broilers were used in the experiment, which was divided into 03 groups, each of which contained 15 broilers. The control group was Group A. Pb (280 mg/kg b. w.) was administered orally to the birds in group B. Group C received Pb (280 mg/kg b.w.) and CF (1 gm/kg b.w.) oral supplements. The research was carried out for 30 days. Blood samples were collected, and sera were prepared for biochemical analysis. Pb accumulation concentration was assessed in muscle, liver and kidney. Moreover, samples of the brain, liver, and kidneys were obtained and prepared for histological analysis. Results: Pb affected hematological markers (Total RBC, Hb conc., hematocrit value, differential leukocytes and blood indices), which were restored with CF supplementation. In Pb-treated broilers, hepatic enzymes (AST, ALT), renal biomarkers (creatinine, total protein and albumin) and lipid profile (TC, TG, HDL and LDL) increased substantially (p < 0.05), but dropped significantly (p < 0.05) after CF supplementation. Pb accumulation was higher in liver, kidney and muscle tissue that was reduced by CF treatment. The histopathological study demonstrated that there was accumulation of fluid around in brain, hyperplasia of bile duct and glomerular epithelium in Pb intoxicated broilers and these were restored after CF supplementation. Conclusions: Therefore, it can be concluded that CF supplementation restored the lead induced detrimental effects on broilers. So, CF has remodulatory effects on Pb toxicity.

    Abstract Abstract Background Vitamin E and black seed oil are two powerful antioxidants with several health benefits. Objective The effect of vitamin E and black seed oil on reproductive performance of Swiss albino mice was studied. Methods A total of 80 (40 male and 40 female) mice of 25–28 days old were randomly divided into four groups viz., A, B, C and D consisting of 10 mice in each group. Mice from the group A served as vehicle control and received normal mice ration whereas mice from the group B, C and D received feed supplemented with either black seed oil (0.5 ml/kg), vitamin E (200 mg/kg) or combination of black seed oil (0.5 ml/kg) and vitamin E (200 mg/kg), respectively daily for 16 weeks. At the end point of the study, blood samples were collected and sera were separated for hormonal analysis. At the same time, mice were sacrificed and testes and ovaries were collected for histomorphological examination. Results In male mice, the level of testosterone increased significantly in mice receiving black seed oil only, whereas the thyroxin increased significantly in all treated groups when compared to the control mice. Histomorphological examination revealed a significant increase in the diameter of seminiferous tubules in male mice fed with either black seed oil or vitamin E or both. On the other hand, the oestradiol and thyroxin concentration in female mice showed no significant changes in both control and treated groups. However, ovaries of mice fed with black seed oil or vitamin E or both showed an increased number of the follicles of different stages than the control mice. Conclusions The findings highlighted the promoting action of vitamin E and black seed oil on reproductive functions of mice and that can be used to treat infertility in man and animals.

    Abstract A butter-enriched high-fat diet changes lipid metabolism, resulting in fat storage, hyperlipidemia and obesity. Effects of cinnamon powder were investigated in butter-fed mice. 40 Swiss Albino mice, aged 28 to 30 days, were randomly assigned into two groups. Group A was an untreated control group (n = 8) and another group (n = 32) was a butter-treated group fed 10% butter. In the fifth week, mice of the butter-fed group were further divided into four equal groups: B, C, D, and E (n = 8), fed 10% butter with cinnamon 200 mg, 400 mg, and 600 mg powder per liter drinking water, respectively for 10 weeks. The butter-fed group was gained the most weight. Cinnamon supplementation significantly normalized weight gain and had no harmful effects on hematological parameters. Butter supplementation significantly increased total cholesterol (TC), triglycerides, and LDL cholesterol (LDL-c) whereas, cinnamon powder significantly reduced TC, LDL-c and glucose levels. In butter-fed mice, a significant increase was observed in the liver enzymes, alanine aminotransferase (ALT) and aspartate aminotransferase (AST) levels with subsequent fat deposition in the liver. Excitingly, these enzymes were decreased and no fat depositions were observed in the liver of cinnamon-treated mice. Applying different concentrations of cinnamon powder improved the lipid profile in butter-fed female albino mice.

    Abstract Bisphenol-A (BPA) is an endocrine disruptor that is widely used in the manufacture of polycarbonate plastics, epoxy resins and dental sealants. It has adverse effects on reproduction. Black seed oil is frequently used as folk medicine for the promotion of good health and treatment of many ailments. The study was carried out to investigate the effect of Bisphenol-A (BPA) and black seed oil (BSO) on hematological parameters, hormone, sperm parameters and patho-physiological changes of testis in mice. A total of 15 male Swiss Albino mice (Mus musculus), of 25-28 days were used and randomly divided into 3 groups consisting 5 mice in each group. Group A served as vehicle control whereas group B and group C were as BPA and BPA plus BSO group respectively. Both BPA @ 50 mg/kg/day and BSO @ 1ml/kg/day were administered orally. Results revealed that BPA caused reduced hematological parameters (Hb, TEC, and PCV) in mice. Inclusion of BSO in BPA treated mice prevented the alterations of those values. Serum T4 and testosterone concentration were significantly (p [J Bangladesh Agril Univ 2021; 19(2.000): 223-229]

    Abstract Objective: The present work was conducted on Cobb-500 broilers fed with either probiotics (Yogurt, Promax®) or antibiotic growth promoters (Ciproflox®, Renamycin®) to assess the effects on body weight and biochemical parameters. Materials and methods: A total of 30 day-old broiler chicks were purchased and acclimatized for 7 days in the experimental shed. After initial acclimatization, the broilers were allotted into five equal groups (n=6). Group A was considered as control and was fed commercial ration and fresh drinking water. Groups B and C were fed commercial ration and probiotics (Yogurt, Promax®) respectively mixed in water. Groups D and E received commercial ration and antibiotic growth promoters (Ciproflox®, Renamycin®) respectively with water. Body weight of each bird was recorded on day 7, 14, 21, 28 and 35. At the end of trial period, the birds were sacrificed to collect blood in order to prepare serum samples for biochemical analyses considering total cholesterol, triglyceride, high density lipids (HDL), creatinine, alanine aminotransferase (ALT) and aspartate aminotransferase (AST). Results: Body weight in all treatment groups (B, C, D and E) was significantly (P<0.05) higher as compared to control (A) group. Total cholesterol and triglyceride levels significantly (P<0.05) decreased in probiotics treated groups as compared to control and antibiotic growth promoters treated groups. AST and ALT values increased significantly (P<0.05) in antibiotic growth promoters treated groups as compared to control whereas, these values decreased in probiotics treated groups. Creatinine levels were significantly (P<0.05) higher in antibiotic growth promoters treated groups as compared to all others groups. Conclusion: Significantly increased body weight is observed in probiotics and antibiotic growth promoters supplemented broilers. Probiotics also improve the lipid profile and other biochemical parameters as compared to growth promoter. Probiotics (like Yogurt and Promax®) seem to be better choice ...

    Abstract Objective: The study investigated the effect of different stocking density (SD) rates on the welfare, growth, and hemato-biochemical parameters in broiler chickens. Materials and Methods: 106 broiler chicks of 10 days old were used and assigned into four groups: A, B, C, and D. The chicks of group A were reared in floor space containing one bird per square foot area (SD1.0). The chicks of groups B, C, and D were reared at 1.5, 2.0, and 2.5 birds per square foot area (SD1.5, SD2.0, and SD2.5). Welfare, body weight, and hemato-biochemical parameters were assessed and monitored by physical observation and laboratory methods. Results: The birds reared at SD2.0, and SD2.5 rates showed increased panting breathing. Wet feces adhered below the vent. There were a significant number of birds showing dirtiness of body and feathers. Birds reared in SD2.5 were familiar with moist litters and high ammonia smell. Foot-pad dermatitis, scratches, and blister formation were detected in the leg. The study revealed that the higher SD negatively correlated to the welfare behavior indicators. Live body weight was significantly (p < 0.05) decreased in birds reared at higher SD rates. Birds housed in SD1.0 and SD1.5 are optimum for body weight and improved feed conversion ratio. The hemato-biochemical parameters of birds reared at various SD rates did not differ. The total leucocyte count increased significantly, while total serum proteins decreased gradually as SD rates increased. Conclusion: This work explores that higher SD negatively affects welfare and growth performance in broiler chickens. [J Adv Vet Anim Res 2021; 8(4.000): 642-649]

    Abstract Summary: Plasmacytoid dendritic cells (plasmacytoid DC, pDC) are major IFN-I producers and have been shown to be affected by HIV through ill-defined mechanisms. In this study, we directly assess the role of pDC in early infection, evaluating whether modulating their abundance can alter viral replication. First, HIV infection of humanized mice induces systemic depletion of pDC, and in the presence of soluble FMS-like tyrosine kinase 3 ligand (Flt3L), pDC levels remain elevated. Flt3L significantly delays the onset of viremia and reduces viral replication via a process that is dependent on pDC and mediated through an enhanced early IFN-I response. pDC from Flt3L-treated mice are more prone to express IFN-α following TLR7 stimulation, but this propensity is gradually decreased during infection. In conclusion, maintaining pDC levels and function is key to effective early viral control, and in this context, these findings provide practical insights for anti-HIV strategies and vaccine design. : Plasmacytoid DC (pDC) are vital for a host’s early antiviral responses. Pham et al. demonstrate that HIV infection of hu-mice induces widespread depletion of pDC and impairs their ability to make IFN-α. Flt3L treatment expands pDC and suppresses HIV replication through early enhancement of IFN-I responses.

    Abstract Levamisole is an anthelmintic drug commonly used for the treatment of parasitic diseases. It triggers immunity in livestock. The research was conducted to evaluate the levamisole (LMS) effects on growth performances, humoral immunity and selected hemato-biochemical parameters in broilers chickens. A total of 40, thirteen days old Lohman broiler chicks were reared up to 33 days with routinely vaccinated. The chicks were randomly divided into four equal groups: A, B, C and D (n=10). The group A was considered as control (neither vaccinated, not treated). The other three groups were vaccinated with Newcastle disease and infectious bursal Disease live vaccine on 15 days of age. Group B was only vaccinated. Group C and D were provided with levamisole hydrocloride (Hcl) at a dose rate of 3 mg / kg and 10 mg / kg body weight, respectively through drinking water from 16th day at twenty four hours interval for five successive days. Results showed that LMS treated broilers had significantly (p [J Bangladesh Agril Univ 2020; 18(5.000): 858-863]
