Toxicological empirical research suggests that excessive utilization of paraquat, an herbicide, shows detrimental consequences on mammalian reproductive toxicity. The current study aims to study it as a reproductive toxin on the caprine testicular cells at 4- and 6-hour exposure duration. Paraquat treatment decreased the cell viability percentage and induced histological architectural alterations such as disruption of germinal epithelium, vacuolization, and pyknotic nuclei in the testis. The differential EB/AO staining also revealed an increased incidence of apoptosis after paraquat treatment at both dosages, i.e. 10 mM and 100 mM. Paraquat also induces oxidative stress, as evident via increased Malondialdehyde levels (a byproduct of lipid peroxidation) and a decline in the antioxidant capacity (FRAP). However, co-administration of Vitamin E significantly reduced the paraquat-mediated decline in cell viability percentage, histological alterations, and apoptosis incidences and generated oxidative stress, indicating its antioxidative properties against paraquat exposure. This research concludes that Vitamin E co-administration considerably reduced the toxicity of paraquat elicited in testicles, suggesting that Vitamin E may have advantageous potential in preventing the male gonadotoxicity caused by paraquat use in agriculture.
毒理学实证研究表明,过度使用除草剂百草枯会对哺乳动物生殖毒性产生有害影响。当前研究旨在研究其在4小时和6小时暴露时长下对山羊睾丸细胞的生殖毒性。百草枯处理降低了细胞活力百分比,并诱导了组织学结构改变,如睾丸中生精上皮破坏、空泡化和核固缩。差异EB/AO染色还显示,在10 mM和100 mM这两种剂量下,百草枯处理后细胞凋亡发生率均增加。百草枯还会诱导氧化应激,这通过丙二醛水平升高(脂质过氧化的副产物)和抗氧化能力下降(FRAP)得以体现。然而,维生素E的共同给药显著降低了百草枯介导的细胞活力百分比下降、组织学改变和细胞凋亡发生率,并产生了氧化应激,表明其对百草枯暴露具有抗氧化特性。本研究得出结论,维生素E的共同给药显著降低了百草枯在睾丸中引发的毒性,表明维生素E在预防农业中使用百草枯引起的男性性腺毒性方面可能具有有益潜力。
