To investigate the effect of Lippia multiflora (Verbanaceae) on the reproductive activity of male Wistar rats, three groups (A,B and C) of rats were treated with 400, 800 and 1600 mg/kg/day of Lippia multiflora leaves extract respectively for 28 days while 5ml/kg of distilled water was given to the control group D. At the end of the experimental period, animals were sacrificed and sperm characteristics, histology of the testes and epididymis were assessed. Lippia multiflora leaf extract caused a significant reduction (P<0.05) in sperm motility, a statistically significant dose dependent reduction in the sperm count and a significant (P<0.05) dose dependent increase in morphological abnormalities of the spermatozoa of the treated rats. Histopathological evaluation of the testis and epididymis revealed varying degrees of degeneration and necrosis of the germinal epithelia cell of the seminiferous tubules, spermiostasis and complete epididymal aspermia. Lippia multiflora leaf extract has significant anti-spermatogenic effects on adult male Wistar rats which could impair reproductive activities in these rats

Abstract Objectives This study aimed to access the protective effects of d-ribose-l-cysteine (DRLC) on cyclophosphamide (CPA) induced gonadal toxicity in male rats. Methods Forty-eight male Sprague-Dawley rats were divided into six groups of eight rats each. Group I the control, received distilled water (10 ml/kg), Group II received a single dose of CPA 100 mg/kg body weight intraperitoneally (i.p), Groups III and IV received a single dose of CPA at 100 mg/kg (i.p) and then were treated with DRLC at 200 mg/kg bodyweight (b.w) and 400 mg/kg b.w for 10 days, respectively. Rats in Groups V and VI received DRLC at 200 and 400 mg/kg b.w for 10 days, respectively. DRLC was administered orally. Results Results showed that CPA increased percentage of abnormal sperm cells and reduced body weight, sperm count, sperm motility, follicle-stimulating hormone (FSH), luteinizing hormone (LH) and testosterone levels (p<0.05). CPA also induced oxidative stress as indicated by the increased malondialdehyde (MDA) content and reduced activities of the oxidative enzymes measured (p<0.05). Liver enzymes were elevated while the blood cells production was decreased in the rats administered CPA. DRLC supplementation enhanced the antioxidant defence system as indicated in the reduced MDA levels and increased activities of the antioxidant enzymes when compared with CPA (p<0.05). Bodyweight, sperm count, sperm motility, FSH, and testosterone levels were increased in the CPA + DRLC II group compared with CPA (p<0.05). Conclusions The results of this present study showed that DRLC has a potential protective effect on CPA-induced gonadotoxicity.

The present work was undertaken to evaluate antidiarrheal activity of ethanolic leaf extract of Dissotis multiflora (Sm) Triana (D. multiflora) on Shigella flexneri-induced diarrhea in Wistar rats and its subacute toxicity. Diarrhea was induced by oral administration of 1.2 × 109 cells/mL S. flexneri to rats. Antidiarrheal activity was investigated in rats with the doses of 111.42 mg/kg, 222.84 mg/kg, and 445.68 mg/kg. The level of biochemical parameters was assessed and organs histology examined by 14 days’ subacute toxicity. S. flexneri stool load decreased significantly in dose-dependent manner. The level of ALT increased (p<0.05) in male rats treated with the dose of 445.68 mg/kg while creatinine level increased in rats treated with both doses. In female rats, a significant decrease (p<0.05) of the level of AST and creatinine was noted in rats treated with the dose of 222.84 mg/kg of D. multiflora. Histological exams of kidney and liver of treated rats showed architectural modifications at the dose of 445.68 mg/kg. This finding suggests that D. multiflora leaf extract is efficient against diarrhea caused by S. flexneri but the treatment with doses lower than 222.84 mg/kg is recommended while further study is required to define the exact efficient nontoxic dose.

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.

Ethanolic Leaf Extract

Diabetes mellitus is an endocrine and metabolic disorder of humans and animals characterized by hyperglycemia and low blood insulin levels or insensitivity of target organs to insulin and it’s a major health problem affecting patient’s quality of life due to its many complications. Infertility is one of the major secondary complications in diabetes. Although numerous drugs have been used for intervention studies on diabetes-induced infertility worldwide, there are currently no treatments for diabetes associated infertility in humans. This study was performed to investigate the effects of Annona muricata ethanolic leaf extract (AMELE) on fertility of male diabetic rats and levels of blood glucose. Twenty male Wistar rats (150-200g) were randomly distributed into 4 groups (n=5) treated thus: CTRL (control), DNT, DT1 and DT2 (diabetic, single intraperitoneal injection, streptozotocin, 60 mg/kg). Group DT1 and DT2 received AMELE orally at 100 mg/kg and 200 mg/kg respectively daily for fourteen days. Data were analysed using ANOVA at α0.05. The animals were sacrificed after 2 weeks via thiopental injection and testicular weights were recorded. Fasting blood glucose was determined using a digital glucometer. Sperm count, motility, viability and morphology were assessed microscopically. Testes were histologically evaluated. The results showed that oral administration of AMELE at 100 mg/kg and 200 mg/kg to diabetic male rats for fourteen days significantly decreased blood glucose level and also ameliorated diabetes-induced decreases in sperm functions in streptozotocin-induced diabetic male rats.

ABSTRACT The hypothalamic-pituitary gonadal axis was studied in young adult (3 month old) and old (24 to 27 month old) male Wistar rats. Plasma testosterone decreased significantly in old animals (x̄: 262 ng/100 ml (n = 35); versus x̄: 110 ng/100 ml (n = 30)). The fall in LH was less pronounced but still significant (54.5 ng LH-RP-1/ml in young versus 39.5 ng/ml in old rats). Groups of 6 to 8 animals of both ages were castrated and implanted with silastic capsules continuously releasing testosterone. The length of the capsules was directly proportional to the plasma testosterone levels achieved (range between 63 and 350 ng/100 ml). After one week young castrated rats not substituted with testosterone showed LH values three times higher (x̄: 351 ng/ml) than old rats treated in the same way (x̄ = 126 ng/ml). LH values in the animals substituted with testosterone indicate that the sensitivity of the negative testosterone-LH feedback is greatly increased in old rats. Testosterone can be depressed to 60 ng/100 ml before an increase in LH occurs. In young rats no increase in LH was observed when testosterone values were higher than 170 ng/100 ml. In the range between 170 and 100 ng/100 ml about half of the young animals reacted with increased LH secretion, while an increase was observed in all young animals when testosterone dropped below 100 ng/100 ml.

AbstractIntroduction: The study aimed to investigate the anti-fertility effect of fennel (Foeniculim vulgare Mill) seed extract in male rats.Material and Methods: Forty Wistar rats were divided into five equal groups. The control group received distilled water and the experimental groups were orally administered 1 ml of hydro-alcoholic extract of fennel seed in four doses of 35, 70, 140, and 280 mg/kg/b.w. daily for 60 days. After the last gavage, the rats were anaesthetised and the caudal part of the right epididymis was used for sperm counting. After fixation of the testes, microscopic sections were prepared and histological changes were evaluated.Results: The number of spermatogonia after doses of 140 and 280 mg/kg and Sertoli cells after a dose of 140 mg/kg decreased significantly as compared with the control group (P < 0.05). The number of primary spermatocytes and sperm count decreased significantly in the experimental groups (70, 140, and 280 mg/kg) when compared to the control group (P < 0.05). Furthermore, thickening of the basement membrane, cell apoptosis, and irregular arrangement of the germinal epithelium were observed in the experimental groups.Conclusion: Hydro-alcoholic fennel seed extract at these doses could reduce reproductivity and has anti-fertility activity in male rats.

Cottonseed oil is an extract from the seeds of cotton plant, that is rich in protein, carbohydrate and fiber.          The objective of the research was to study the effect of cottonseed oil on the histology of the testis.          Materials and methods. Twelve adult male Wistar rats weighing 200 – 250g, were randomly sorted into four groups (I - IV), each containing three animals. Cottonseed oil was administered orally to the experimental animals by means of an orogastric tube. The rats in Group I (the control group) received standard rat pellet and oral normal saline ad libitum only. The animals in Groups II, III, and IV received 0.2 ml, 0.6 ml and 1.0 ml of cotton seed oil per body weight respectively. On the 21st day, the animals were sacrificed by cervical dislocation. The testes were excised and, then, fixed with appropriate fixatives for routine tissue processing.          Results. The results revealed an increase in the luminal diameter of seminiferous tubules, a decrease in the Leydig cell population, the disorientation of spermatogenic series and their detachment from the germinal epithelium.          Conclusions. The present study demonstrated that oral administration of cottonseed oil to male rats displayed a deleterious effect on their testis by disrupting spermatogenesis and the histological architecture of the testis.

Introduction: Medicinal plants such as Cnidoscolus aconitifolius (CA) have been studied over the years for their protective and curative potentials against a myriad of common global health challenges such as hepatorenal injuries. Objectives: To ascertaining the effects of the hydromethanol leaf extract of CA (HMLECA) on hepato-renal parameters in adult male wistar rats. Method: A total of 18 adult male wistar rats were divided into 3 groups of six rats each. Group I served as the negative control which received distilled water while groups 2 and 3 served as extract treatment groups which received 200 and 400 mg/kg BW of the HMLECA respectively. The administration was daily for a period of 58 days while blood sample for the biochemical analysis was drawn via cardiac puncture at the end of the study following light chloroform anaesthesia. Results and Discussion: The results showed that the administration of both doses of the extract produced no significant (P<0.05) effect on the levels of serum liver enzyme (AST, ALT, ALP), TP, ALB, electrolytes (K+, Na+ and HCO3–), Creatinine and Urea while that of the 400 mg/kg BW produced significant (P<0.05) decrease in the level of TB and Cl –. Hence, the administration of the leaf extract in this study did not elicit any toxic effect on both the liver and kidney functions and could be effective as hepato-renal protective agent.
