Study was undertaken to evaluate ameliorative potential of α-tocopherol against copper sulphate and flubendiamide alone and in combination-induced toxicity in rats following 90 days exposure. Absolute and relative organ weights did not differ between treatments groups. Increase of LPO in copper and flubendiamide intoxicated rats but modest increase in copper + flubendiamide group. GSH and activities of SOD, GPx and GST showed moderate decrease in intoxicated groups. Reduced CAT activity in alone exposed groups was observed. ACP, ALP and SDH remain unaltered. Increase in LDH, γ-GT, abnormal sperm and reduced 17β-HSD, percent live and HOST +ve sperms and testosterone level was observed in all three exposed groups. Xenobiotics alone and in combination exhibited degenerative germinal epithelium, necrotic germ cells, loss of spermatozoa and spermatids. Treatment with α-tocopherol, reparative potential was observed as values of most of the parameters including testicular histoarchitecture were restored.
本研究旨在评估α-生育酚对硫酸铜和氟苯脲单独及联合暴露 90 天后诱导大鼠毒性的改善潜力。各组大鼠的绝对和相对器官重量无差异。铜和氟苯脲中毒大鼠的 LPO 增加,但铜+氟苯脲组略有增加。GSH 和 SOD、GPx 和 GST 的活性在中毒组中呈中度下降。单独暴露组的 CAT 活性降低。ACP、ALP 和 SDH 保持不变。所有三个暴露组的 LDH、γ-GT、异常精子和减少的 17β-HSD、活精子百分比和 HOST+阳性精子以及睾酮水平均升高。单独和联合使用的外源化学物质表现出生殖上皮退化、坏死的生殖细胞、精子和精子细胞丢失。用α-生育酚治疗后,观察到修复潜能,包括睾丸组织形态学在内的大多数参数的数值均得到恢复。
