THE EFFECT OF ETHANOLIC EXTRACT OF BRYOPHYLLUM PINNATUM ON THE MICRO ANATOMY OF THE TESTES OF ADULT MALES WISTER RATS (Published)
The main aim of this research study is to determine the effect of ethanolic fractions of bryophyllum pinnatum leaves on the male testes using adult male wistar rats. Thirty (30) adult male wistar rats were divided into three groups of ten rats each. Group (A) serve as the control group and was administered with distilled water, Group (B) was treated with 100mg/kg/body weight of the bryophyllum pinnatum extract. Group (C) received 200mg/kgbw of the extract. The treatment lasted for a duration of 8weeks. The rats were sacrificed the day after the last dose and the testes were removed and processed for histological studies. The results from the treated groups showed increase intercellular spaces within the seminiferous epithelium, shrunken and increase lumen, suggesting cells disintegration. This is indicative that bryophyllum pinnatum extract may have adverse effect on the testes of the treated rats
Possible Ameliorative Role of Low Dose of Radiation Againstcisplatin Induced Oxidative Stress and Tissue Damage Male Rats (Published)
The present study describes antioxidant effect of low dose of radiation against cisplatin induced toxicity in rats. Oxidative stress was induced in rat by a single dose of cisplatin (10 mg/kg body weight I.P), 24 hr post- cisplatin treatment, the animals exposed to 0.3 Gy single dose of gamma ray. The effect of treatments in influencing the oxidative stress as well as biochemical cisplatin changes on brain, kidney and testis were studied. The data showed significant increase in serum urea, creatinine, creatine kinase isoenzymes (CKBB) and tumor necrosis factor (TNF-α) as well as in tissue MDA levels in animals treated with cisplatin while this effects were attenuated by radiation exposure. Moreover, treatment with cisplatin caused a significant decrease in serum testosterone and tissues SOD activities, which was shown to be reversed by low dose of radiation treatment. Treatment with low dose of radiation significantly reduced the oxidative stress effects induced by cisplatin administration. It can be concluded that exposed animals to a low dose of radiation after cisplatin treatment can speed the recovery of the body during the chemotherapeutic treatment.
