Treatment with dams with dexamethasone during lactation has been reported to induce oxidative stress in the testis of the offspring. (Red Onion) is known to be a potent free radical scavenger. The protective role of against oxidative stress induced in testis following treatment with dexamehasone during lactation in Wistar rats was assessed. Twenty female rats were assigned into four groups (n = 5) during lactation and they were treated as follows: Group 1 serve as Control (distilled water), Group 2, 3, and four were admistered dexamethasone (60 μg/kg), (5 ml/kg) and dexamethasone + respectively. Testicular descent, pubertal age, sperm quality indices, and serum hormonal profile were assessed as indices of reproductive function. Testicular malondialdehyde (MDA) reduced glutathione (GSH) as well as superoxide dismutase (SOD) and catalase activities were assessed as measures of oxidative stress. Results obtained showed that dexamethasone caused significant (P < 0.05) reduction in testes weights, indices of sperm quality, serum testosterone, FSH, LH levels and testicular antioxidant enzyme activities. There was significant delay (P < 0.05) in days of testes descent, preputial separation and increase in testicular MDA. However, maternal treatment with juice significantly (P < 0.05) improved both indices of reproductive function and testicular antioxidant enzymes. These findings suggest that has a protective effect against testicular oxidative stress and reproductive dysfunction following treatment of dams with dexamethasone during lactation.
据报道,哺乳期用含地塞米松的药物处理会导致后代睾丸出现氧化应激。红葱已知是一种有效的自由基清除剂。本研究评估了红葱对哺乳期经地塞米松处理的Wistar大鼠睾丸氧化应激的保护作用。20只雌性大鼠在哺乳期被分为四组(每组n = 5),并进行如下处理:第1组作为对照组(蒸馏水),第2组、第3组和第4组分别给予地塞米松(60 μg/kg)、红葱汁(5 ml/kg)以及地塞米松 + 红葱汁。评估睾丸下降、青春期年龄、精子质量指标和血清激素水平作为生殖功能指标。测定睾丸丙二醛(MDA)、还原型谷胱甘肽(GSH)以及超氧化物歧化酶(SOD)和过氧化氢酶活性作为氧化应激指标。结果显示,地塞米松导致睾丸重量、精子质量指标、血清睾酮、促卵泡激素(FSH)、促黄体生成素(LH)水平以及睾丸抗氧化酶活性显著降低(P < 0.05)。睾丸下降天数、包皮分离明显延迟(P < 0.05),睾丸MDA增加。然而,母鼠用红葱汁处理显著(P < 0.05)改善了生殖功能指标和睾丸抗氧化酶。这些发现表明,红葱对哺乳期母鼠经地塞米松处理后睾丸氧化应激和生殖功能障碍具有保护作用。
