This study evaluated the ameliorative and prophylactic effects of 2 different doses of polyphenolic-rich fraction of Garcinia kola (PPRF Gk) seeds on the histology and hormones of pituitary–testicular axis of male Wistar rats. Thirty-five male Wistar rats (150-200 g) were divided into 7 groups of 5 rats each. Groups I and II were given distilled water (0.5 mL/day) for 8 days followed by propylene glycol (0.2 mL/d) and 600 mg/kg of PPRF Gk, respectively, for 21 days. Group III received sodium arsenate (8 days), left untreated for 21 days. Groups IV and V received sodium arsenate (20 mg/kg) for 8 days followed by PPRF Gk (300 and 600 mg/kg, respectively) for 21 days. Groups VI and VII received PPRF Gk (300 and 600 mg/kg, respectively) for 21 days followed by sodium arsenate (20 mg/kg) for 8 days. Rats were killed by cervical dislocation 24 hours after the last dose and their blood collected through cardiac puncture. Blood sera were assayed for the levels of follicle-stimulating hormone (FSH), luteinizing hormone (LH), and testosterone using immunoassay techniques. Histology of the pituitary gland and testes was carried out. A significant reduction was observed in the concentration of FSH in groups IV, V, VI, and VII in comparison with groups I and II. The concentrations of both LH and testosterone showed significant decreases in groups IV, V, VI, and VII in comparison with group I. Group III presented with the lowest serum hormonal concentrations. Photomicrographs of the pituitary gland revealed greatly reduced basophils in group III and mildly reduced basophils in groups IV, VI, and VII in comparison with groups I and II. Group V revealed hypercellularized and distorted basophils. Photomicrographs of the testes showed detachment of the seminiferous tubules from the basement membrane and disruption of the interstitial space which was worse in group III, moderate in groups V and VI, and mild in group VII. In conclusion, PPRF Gk effected a dose-dependent reversal and prevention of the perturbations caused by arsenate in rats.

Abstract Introduction: The histopathology and expression of nucleolar organizing regions (NORs), of seminiferous tubules was studied after the administration of methotrexate (MTX) and vitamin A (VA). Objective of the study was to test if the NOR count increases or decreases with different doses of MTX. Material and Methods: Male Wistar rats aged 4 months, maintained in our institution were used in the present study. The rats were divided into following groups, group I - control (saline treated), group II - animals treated with 8 mg of MTX, group III - animals treated with 10 mg of MTX, group IV - animals treated with 12 mg of MTX, group V - animals treated with VA (5000 IU), Group VI - animals treated with VA (5000 IU) and MTX (12 mg). Results: The animals treated with MTX showed significant decrease in the diameter of seminiferous tubules and increase in interstitial space. The spermatogenesis was not complete in some tubules. When MTX was given with VA, the damage done by MTX was decreased. There was an overall numerical decrease in the total NOR count from the control to 12 mg dose MTX. The total count included small, medium and large sized NORs. Conclusion: Higher the dose of MTX, lesser the NOR count and lesser the irregularity of NORs. However VA co-administration reduces the damage produced by MTX. We believe that indings of the present study might be useful in understanding the long term effect of MTX and its adverse effects.

Tuberculosis Therapy

The liver is the primary organ that metabolizes the majority of the drug. Toxicity caused by these drugs to the liver is called hepatotoxicity. Hepatotoxicity is a major concern in tuberculosis therapy, especially Rifampicin - Isoniazid (R-H). Studies showed that these drugs induce oxidative stress in the liver. This study attempts to determine whether the ethanolic extract of Physalis ixocarpa (EEPI) protects against R-H induced hepatotoxicity in adult male Wistar rats. Adult male Wistar rats were divided into five groups (each group n=6 animals). Group I, control treated with normal saline (5ml/kg, b/w, p.o.). Group II, Hepatotoxicity induced by combination of R-H (each 50mg/kg, i.p.) administered up to 14 days. Group III and IV, EEPI (100 mg/kg & 200 mg/kg, b/w) were administered orally one hour before the R-H inducing agent up to 14 days. Group V, Silymarin (25 mg /kg, b/w., p.o.) was served as standard. After 14th days animals were allowed fast overnight and blood was collected through orbital puncture and animal was sacrificed then liver tissue was collected for biochemical analysis and histopathological studies. Our results show a significant reduction in the level of alkaline phosphate (ALP), alanine transaminase (ALT), aspartate transaminase (AST) and total bilirubin. Treatment with EEPI also showed a significant increase in the activity of antioxidant enzymes and decreased levels of malondialdehyde (MDA) in the liver. EEPI also reduced the macrovesicular steatosis and ballooning caused by the R-H. The present study demonstrates that administration of ethanolic extract of Physalis ixocarpa ameliorating hepatoprotective activity as evidenced by the biochemical and histopathological parameters.

Abstract Introduction: AAzathioprine and Methotrexate are both used in the treatment of cancer; and are classified as cytotoxic drugs with reported adverse effects such as oxidative damage to the DNA/RNA, the testes and sperm cells. This study, therefore, tested the hypothesis that AAzathioprine and Methotrexate administrations impair the morphology and functions of the testes in adult male wistar rats. Methods: AAzathioprine (50-150mg per day) and Methotrexate (2.5mg per week) are used in the treatment of cancer in adult Man. We tested the hypothesis that AAzathioprine and Methotrexate impair the morphology and functions of testes in rats. Forty adult male wistar rats (150-230g) were employed in the study: Control Group I received physiological saline while Experimental Groups II - V received oral administrations of 5mg/kg/bodyweight of AAzathioprine per day, 15mg/kg/bodyweight of AAzathioprine per day, 8mg/kg/bodyweight of Methotrexate per week and 20mg/kg/bodyweight of Methotrexate per week respectively for 35 days. Results: Histological examinations of the testes of rats of Groups II - V showed dose-dependent morphological anomalies such as fewer collagen ibers of connective tissues, disrupted seminiferous tubules and scanty spermatozoa when compared to rats of Group I. Statistical analyses showed dose-dependent elevated levels (P≤0.05) of superoxide dismutase and malondialdehyde in testes homogenates of rats of Groups II - V when compared to rats of Group I. This implied increased oxidative stress in rats of Groups II - V. Evaluations of Follicle Stimulating Hormone and Testosterone showed dose-dependent significantly elevated levels (P≤0.05) in rats of Groups II - V when compared to rats of Group I. Conclusions: Our findings are consistent with the stated hypothesis.

The objective of this study is to investigate the functions of parotid and pancreatic glands in response to intoxication with parathion-methyl (PM) and the effects of treatment in rats. Seventy-five male Wistar rats were divided equally into five groups: Group I, control; group II, received atropine and pralidoxime (2-PAM) for 24 h, but no PM; group III, oral PM but no atropine and 2-PAM; group IV, PM and atropine for 24 h and 2-PAM; group V, PM and atropine for 96 h and 2-PAM. After the administration of the chemicals, blood samples were drawn to test for amylase, lipase, acetylcholinesterase (AChE), and butyrylcholinesterase (BChE), while pancreatic and parotid glands of each rat were removed for light microscopic examination. Amylase levels were found significantly elevated in groups II, III, IV, and V, whereas lipase levels were supranormal in groups III, IV, and V. The blood levels of AChE were decreased in groups III and IV and BChE were decreased in II, III, IV, and V. No evidence of pancreatitis and parotitis was identified in the histopathologic evaluation in any group in 96 h; however, hyperchromasia, irregularity in nuclei, and binuclear cells were observed in all parotid glands in group V. Parotitis and pancreatitis were not evident; however, hyperamylasemia and hyperlipasemia were found, whereas various histologic changes in parotid glands were documented in the groups that were administered organophosphate and treatment.

Summary The effect of aqueous matured stem extract of Opuntia dillenii on selected biochemical parameters in Male Wistar rats was explored. Standard analytical methods were applied. Forty Wistar rats (80-100g) were used in the animal studies, separated into four groups. The control group was solely administered normal feed and saline, group I was administered 100mgkg−1 of the extract, group II received 300mgkg−1 of the extract and group III received 500 mg/kg−1 of the extract. A significant increase (p<0.05) in the activities of alanine aminotransferase (ALT) and alkaline phosphatase was observed in group II and III rats, as compared with the controls. A significant decrease in urea and creatinine concentrations was found only in group III rats against the controls. Also, a significant (p<0.05) decrease in triglyceride, total cholesterol, and low density lipoprotein (LDL)-cholesterol was seen in group II and group III rats when compared with the control. The hematological evaluation revealed a significant (p<0.05) decrease in red blood cell and hemoglobin levels in group III rats when compared with the control. The findings showed both beneficial and toxicological effects of the plant. Hence, for optimal therapeutic benefits, a further toxicological survey could still be carried out perhaps at higher doses.

Abstract Male Wistar rats were divided into 3 groups: Group I. Rats given the triamcinolone daily by gastric catheter all developed neutrophilia accompanied by lymphopenia. Group II. Rats given daily intraperitoneal injections of plasma from normal rats manifested no significant alteration in the peripheral blood elements. Group III. Rats given daily intraperitoneal injections of plasma from rats given triamcinolone invariably developed neutrophilia without lymphopenia. Studies of the bone marrow of these groups at the end of the experiments revealed increased myeloid:erythroid ratios in Groups I and III but not II. It is therefore believed that this experiment suggests the existence of a neutrophilia-promoting factor in the plasma following the administration of triamcinolone.

Objectives: To evaluate the anti-oxidative role of Resveratrol in Cisplatin-induced testicular toxicity in Albino Wistar rats. Study Design: Quasi-experimental study. Settings: Department of Physiology and Postgraduate Laboratory of ISRA University Hyderabad. Period: Six months from March to September 2019. Material & Methods: Twenty-four male albino Wistar rats were distributed equally into; Group-I (Control), Group-II (Cisplatin), Group-III (Cisplatin + Resveratrol). Difference in mean pre and post-experimental body weight was observed while analysis of oxidative markers, semen parameters, and histomorphology was carried out in all three groups. SPSS ver. 22 was used to analyze the data. Results: The mean body weight decreased from 241.7±8.5 gm to 196.50±9.34 gm and from 237±7.4 gm to 210.0 ± 6.50gm in groups II and III respectively. Statistically significant reduction in semen parameters (sperm count, motility and viability) was observed in Group-II compared with Group-C (p<0.05). Oxidative markers were also significantly depleted in Group-II in comparison to Group-C (p<0.05). Histologically, testicular structure was found to be intact in Group-I. Marked changes were observed in testicular histology of Group-II while Group-III displayed less testicular damage. Irregular, regressive and atrophic seminiferous tubules were seen in Group-II. Most seminiferous tubules having normal morphology were observed in Group-III while the number of atrophic and degenerative seminiferous tubules also decreased significantly. Conclusion: Resveratrol therapy is a potent protective regime showing promising results in cisplatin-induced testicular toxicity and oxidative stress.

Hepatotoxicity caused by chemotherapeutic drugs (e.g., doxorubicin) is of critical concern in cancer therapy. This study focused on investigating the modulatory effects of diosmin against doxorubicin-induced hepatotoxicity in Male Wistar rats. Male Wistar rats were randomly divided into four groups: Group I was served as control, Group II was treated with doxorubicin (20 mg/kg, intraperitoneal, i.p.), Group III was treated with a combination of doxorubicin and low-dose diosmin (100 mg/kg orally), and Group IV was treated with a combination of doxorubicin and high-dose diosmin (200 mg/kg orally) supplementation. A single dose of doxorubicin (i.p.) caused hepatic impairment, as shown by increases in the concentrations of serum alanine aminotransferase, aspartate aminotransferase, and alkaline phosphatase. Doxorubicin produced histological abnormalities in the liver. In addition, a single injection of doxorubicin increased lipid peroxidation and reduced glutathione, catalase, and superoxide dismutase (SOD) levels. Importantly, pre-treatment with diosmin restored hepatic antioxidant factors and serum enzymatic activities and reduced the inflammatory and apoptotic-mediated proteins and genes. These findings demonstrate that diosmin has a protective effect against doxorubicin-induced hepatotoxicity.

Abstract Objectives Exposure to light-at-night (LAN) has been reported to impair blood glucose regulation. The liver modulates blood glucose through mechanisms influenced by several factors that include peroxisome proliferator-activated receptor gamma coactivator-1alpha (PGC-1α) and glucose-6-phosphatase (G6Pase). This study investigated the effect of intermittent exposure to green and white LAN on some hepatic glucose regulatory factors in male Wistar rats. Methods Animals were divided into three equal groups. Group I (control) was exposed to normal housing conditions. Groups II and III were each daily exposed to either green or white LAN for 2 h (7–9 pm) for 14 days. Body weight and blood glucose was monitored on days 0, 7, and 14. Thereafter, retro-orbital sinus blood was obtained after light thiopental anaesthesia and serum insulin was determined. Liver samples were also obtained and evaluated for glycogen, PGC-1α, and G6Pase activity. Insulin resistance was estimated using the HOMA-IR equation. Results Body weight and blood glucose on days 7 and 14 increased in groups II and III compared to control. Hepatic PGC-1α and G6Pase increased in group II (2.33 ± 0.31; 2.07 ± 0.22) and III (2.31 ± 0.20; 0.98 ± 0.23) compared to control (1.73 ± 0.21; 0.47 ± 0.11). Hepatic glycogen was 71.8 and 82.4% reduced in groups II and III compared to control. Insulin in group II increased (63.6%) whiles group III values reduced (27.3%) compared to control. Insulin resistance increased in group II (0.29 ± 0.09) compared to control (0.12 ± 0.03) and group III (0.11 ± 0.03), respectively. Conclusions Exposure to 2 h green and white LAN in the early dark phase increases hepatic glycogenolysis and gluconeogenetic activities resulting in increased blood glucose. In male Wistar rats, exposure to green but not white LAN may predispose to insulin resistance.
