摘要

背景:吡虫啉是一种新烟碱类杀虫剂,属于氯烟碱基硝基胍化学家族。在科学研究中,IMD对哺乳动物的毒性显示出高度的诱变、免疫毒性、致畸和神经毒性作用。本研究旨在评估吡虫啉(IMD)对新生雄性大鼠睾丸和附睾组织以及睾酮水平的毒性作用。方法:从出生后第1天(PND)至第26天,雄性新生大鼠连续皮下注射不同浓度的IMD(1、5、10 mg/kg)。在睾丸和血浆中评估IMD对身体和器官重量、脂质谱、组织病理学改变、氧化应激和睾酮水平改变的影响。结果:与对照组相比,第4组(10 mg/kg)的增重结果有显著差异。总胆固醇和甘油三酯显著增加,而高密度脂蛋白浓度明显下降。同样,与对照组相比,所有imd处理组的抗氧化酶(CAT和SOD)浓度明显降低。在最高剂量治疗组中,ROS的产生也有所增加。此外,我们观察到,与对照组相比,imd治疗组大鼠的睾丸和附睾出现了组织病理学变化,血浆睾酮浓度显著降低。imd治疗的新生雄性大鼠睾丸的组织学检查也显示,与对照组相比,治疗组的精子发生减少。此外,与对照组相比,imd治疗大鼠的管腔直径增加,精小管上皮高度降低。结论:亚慢性暴露IMD可引起新生雄性大鼠生殖组织病理改变,并通过诱导氧化应激、体重下降、扰乱正常血脂和睾酮浓度等途径损害正常睾丸功能。暴露于IMD可引起病理生理效应,需要进一步评估这种广泛使用的杀虫剂。

Determination of biochemical and histopathological changes on testicular and epididymis tissues induced by exposure to insecticide Imidacloprid during postnatal development in rats.

Background: Imidacloprid is a neonicotinoid insecticide belonging to the chloronicotinyl nitroguanidine chemical family. Toxicity of IMD for mammals in scientific studies has shown high mutagenic, immunotoxic, teratogenic and neurotoxic effects. The present study was designed to assess the toxic effects of imidacloprid (IMD) on the testicular and epididymis tissues as well as testosterone levels of neonatal male rats.

Methods: Neonatal male rats from postnatal day (PND) 1 to PND 26 were consecutively administered with different concentrations of IMD (1, 5 and 10 mg/kg) subcutaneously. The effect of IMD on body and organ weight, lipid profile, histopathological alterations, oxidative stress and altered testosterone levels were assessed in the testis and plasma.

Results: The results of body weight gain showed a significant difference in group 4 (10 mg/kg) animals as compared to the control. A significant increase in total cholesterol and triglycerides, while a decrease in high-density lipoprotein concentrations was evident. Similarly, a significant decrease in concentrations of antioxidant enzymes (CAT and SOD) among all the IMD-treated groups was evident, when compared to the control. Increased production of ROS was also noticed in the highest-dose treatment group. Further, we observed that IMD-treated rats indicated histopathological changes in the testis and epididymis along with a significant decrease in the plasma testosterone concentrations among IMI-treated groups in contrast to the control. Histological examination of the testis of IMD-treated neonatal male rats also showed decreased spermatogenesis in the treated groups when compared to the control. Furthermore, an increase in lumen diameter and a decrease in epithelial height of seminiferous tubules were also observed in IMD-treated rats in comparison with the control.

Conclusion: It is concluded that sub-chronic exposure to IMD in neonatal male rats may induce histopathological changes in reproductive tissues and damage normal testicular functions via inducing oxidative stress, decrease in body weight, disturbing normal blood lipid profile and testosterone concentration. IMD exposure can induce pathophysiological effects calls for further evaluation of this widely used insecticide.
