In some countries, anabolic-androgenic steroid abuse is rampant among adolescent boys and young men, including some of those seeking physical fitness and/or pleasing appearance through various exercise types. This tactic carries the risk of severe harmful health effects, including liver injury. Most anabolic-androgenic steroid stacking protocols employed are based on the use of the ‘prototypic’ anabolic-androgenic steroid testosterone and/or its esters. There is a vast body of data on the effects of anabolic-androgenic steroids’ abuse combined with physical exercise training on the liver antioxidant barrier in adult subjects, whereas those concerning adolescents are scant. This study aimed to assess, in adolescent male Wistar rats undergoing a 6-week moderate-intensity endurance training (treadmill running), the influence of concurrent weekly supplementation with intramuscular testosterone enanthate (TE, 8 or 80 mg/kg body weight/week) on selected indices of liver status and oxidative stress. The rats were sacrificed, and their livers and blood samples were harvested two days after the last training session. High-dose TE treatment significantly reduced body and liver weight gains. Neither low-dose nor high-dose TE treatment affected liver α-tocopherol or γ-tocopherol content, whereas low-dose TE treatment significantly lowered hepatic reduced glutathione content. TE treatment significantly elevated liver thiobarbituric acid-reactive substances content and blood activities of alkaline phosphatase and γ-glutamyltransferase, but not of aspartate aminotransferase or alanine aminotransferase. Liver catalase activity was lowered by >50% in both TE-treated groups, while superoxide dismutase activity was significantly but slightly affected (−15%) only by the high-dose TE treatment. Glutathione peroxidase and glutathione reductase activities were not significantly altered. TE treatment significantly increased liver thiobarbituric acid-reactive substances content and lowered blood HDL-cholesterol, but did not significantly affect LDL-cholesterol or triglycerides level. In conclusion, high-dose TE treatment significantly disturbed liver antioxidant barrier and prooxidative-antioxidative balance and hence counteracted favorable effects of concurrent moderate-intensity endurance training in adolescent male rats.

Objective. To study the effect of Heweianshen decoction (HAD) on orexin-A and cholecystokinin-8 (CCK-8) expression in rat models of insomnia caused by injecting parachlorophenylalanine (PCPA) intraperitoneally.Methods. Fifty male Wistar rats were randomly divided into five groups (10 rats in each group): blank group, model group, and low-, medium-, and high-dose HAD-treated groups. A rat model of insomnia was established by injecting intraperitoneally with PCPA (300 mg/kg body weight). Rats were given normal saline (10 mL/kg) or 5.25, 10.5, and 21 g/kg HAD by intragastric administration once a day for 6 days. After that, the rats were sacrificed to collect the hypothalamus for tests, using radioimmunoassay to detect the expression of orexin-A and CCK-8.Results. Heweianshen decoction reduced the expression of orexin-A and increased the expression of CCK-8 in the hypothalamus of rat model of insomnia.Conclusion. The therapeutic effect of HAD on insomnia is partially attributed to the decreased expression of orexin-A and increased expression of CCK-8.

It is a common practice to dispose the peel or rind of fruits. Interestingly, some parts of fruits humans find unacceptable to eat actually possess bioactive nutrients that can be used for medicinal purposes.  The effect of methanolic extract of Citrullus lanatus rind on liver function in normal male wistar rats was studied. 24 wistar rats with body weight between 150-250 g were used for this study. The animals were randomly divided into four groups, with 6 rats in each. Group 1 contained the control given normal saline and feed; group 2, low dose, 50mg/kg of methanolic extract of  Citrullus lanatus rind was administered, group 3 and 4 were administered medium and high dose of Citrullus lanatus rind extract 100 mg/kg and 200 mg/kg respectively. The Citrullus lanatus rind extract was administered via orogastric route and the experiment lasted for a period of 56 days. Blood samples were collected by left ventricular cardiac puncture for liver function test at the last day of the experiment.  The outcome of this research revealed that medium and high dose administration of citrullus lanatus rind significantly (p≤0.05) reduced the serum level of liver enzymes alanine transaminase, aspartate transaminase and alkaline phosphatase and also total protein.There was a non-significant (P≤0.05) change in serum total bilirubin and albumin when all doses were compared to the control. Prolonged and moderate ingestion of Citrullus lanatus rind may be of benefit in regulating blood level of liver enzymes; hence, this part of the fruit has therapeutic value.

Abstract Introduction: Fetal programming hypothesis presupposes that stimulus or insult acting during critical periods of uterine growth and development do alter tissue structure and function. In the present study changes in histomorphometric integrity of the testes and epididymis in adult F1 male rats maternally exposed to Ricinus communis oil (RCO) at different gestation periods were assessed. Materials and Methods: Therapeutic dose of RCO 950 mg/kg BW was administered to pregnant Wistar rats at gestation days GD 1-7, 7-14, 14-21 and 1-21 respectively. Testes and epididymis of adult male F1 offspring were then harvested for Histomorphometry assessment under Light microscope. Seminiferous tubular diameter (STD), seminiferous luminal diameter (SLD) and Seminiferous epithelial height (EH) of both peripheral and central seminiferous tubules were measured in the testes. Epididymal tubular diameter (ETD), epididymal luminal diameter (ELD) and epididymal epithelial height (EEH) were measured in epididymis. Results: Results were expressed as the mean ± SEM and significance taken at p<0.05. STD significantly (p<0.001) increased in F1 males from GD1-7, 7-14, 14-21 relative to control group. SEH significantly (p<0.001) decreased in F1 males from GD1-7,7-14 and 1-21. SLD increased significantly (p<0.001) in F1males from GD1-7, 7-14, 14-21 and 1-21. ETD significantly (p<0.01) increased in F1 males from GD1-7, 7-14, 14-21. EEH significantly (p<0.001) increased in F1 males from GD1-7 and GD7-14. ELD however increased significantly (p<0.001) only in F1 males from GD1-7. Conclusion: Maternal RCO exposure at different gestation periods impaired negatively histomorphometry of the testis and epididymis in male offspring.
