The aim of the current study was to investigate the ability of dimethoate (DMT) to induce reprotoxicity in male mice. The dose (20 mg/kg/day) was given orally for 30 days. A significant decrease in sperm count, motility and viability and a significant increase of morphologically abnormal spermatozoa percent in DMT treated mice was observed. Testicular Acetylcholinesterase (AChE) and Butyrylcholinesterase (BChE) activities were inhibited. Also, a significant increase in lipid peroxidation level and a significant decrease in the activities of antioxidant enzymes were observed in testis of DMT mice. In addition, gene expression of glutathione peroxidase 4 (GPx4) was quantified in RNA samples extracted from the testis by real-time reverse transcription-polymerase chain reaction (RT-PCR). Compared with control, mRNA expression of GPx4 was slightly decreased after DMT-exposure.
本研究的目的是调查乐果(DMT)诱导雄性小鼠生殖毒性的能力。以20毫克/千克/天的剂量口服给药30天。观察到乐果处理的小鼠精子数量、活力和存活率显著下降,形态异常精子百分比显著增加。睾丸乙酰胆碱酯酶(AChE)和丁酰胆碱酯酶(BChE)活性受到抑制。此外,在乐果处理的小鼠睾丸中观察到脂质过氧化水平显著升高,抗氧化酶活性显著降低。另外,通过实时逆转录-聚合酶链反应(RT-PCR)对从睾丸中提取的RNA样本中谷胱甘肽过氧化物酶4(GPx4)的基因表达进行了定量。与对照组相比,乐果暴露后GPx4的mRNA表达略有下降。
