Abstract

AIM

The aim of this study was to investigate the morphological and functional features of the process of spermatogenesis in the testes of male albino rats when exposed to lead acetate.

MATERIALS AND METHODS

Using histological, morphometric and statistical methods explored the effects of lead acetate on the process of spermatogenesis in the testes of male albino rats. Investigations were carried out using a digital microscope Axio Imager. M2 and automatic cell counter Countess™.

RESULTS

It is shown that when exposed to lead acetate a decrease in the production of all populations of spermatogenic cells, decreased spermatogenesis index and an index of relaxation (tension spermatogenesis), the increase in the index of ripening, index meiotic activity and germinative index, which indicates a decrease in the functional activity of the testes. On preparations, it is possible to see that after the influence of acetate of lead the head of spermatozoa becomes more roundish, breaks of tails observed.

CONCLUSION

Lead acetate reduces the productivity of the seminal glands, which leads to the decrease of the concentration of spermatozoa, and their viability. The results of the studies suggest a negative impact of lead acetate in the course of the process of spermatogenesis in the testes of male white rats.

摘要

目的

本研究旨在探讨雄性白化大鼠睾丸在暴露于醋酸铅时精子发生过程的形态学和功能特征。

材料与方法

采用组织学、形态计量学和统计学方法,探究醋酸铅对雄性白化大鼠睾丸精子发生过程的影响。使用Axio Imager.M2数字显微镜和Countess™自动细胞计数器进行研究。

结果

结果表明,暴露于醋酸铅时,所有生精细胞群体的产生减少,精子发生指数和松弛指数(紧张性精子发生)降低,成熟指数、减数分裂活性指数和生发指数增加,这表明睾丸的功能活性降低。在制剂上可以看到,铅醋酸盐作用后精子头部变得更圆,观察到尾部断裂。

结论

醋酸铅降低了精囊的生产力,导致精子浓度及其活力下降。研究结果表明醋酸铅对雄性白鼠睾丸精子发生过程有负面影响。
