Abstract

BACKGROUND

Precious fruits like jambul are neglected and wasted while environmental pollutants like lead intake remain overlooked.

OBJECTIVE

The aim of this study was to investigate the effects of the Jambul pulp extract on lead detrimental effects in pseudostratified epithelium and the stereocilia of mice epididymis and vas deferens.

MATERIALS AND METHODS

Thirty young males mice (Mus musculus) were distributed randomly in 3 groups (n= 10) called control, Pb (Lead) and Pb-J (Lead-Jambul). The Pb and Pb-J were provided 50ppm Pb in drinking water ad libitum for 15 days and Pb free water for the next 5 days. The Pb-J group received 0.2ml jambul pulp extract on 12 hourly bases. Control group was not given any treatment. Organs (epididymis and vas deference) were recovered on 21(st) day after euthanasia. The organs were finally processed for histological and micrometric studies.

RESULTS

Marked histologic and micrometric changes in both organs were noted in Pb group. These include significant (P ≤ 0.05) decrease in cross sectional area of caput and cauda epididymis folding tubing along with evident alterations of their endothelial thickness. Prominent signs of apoptosis (vacuolations) in the corpus pseudostratified endothelium and the destruction of stereocilia of the epididymis and vas deferens in Pb compared to control group were observed. Evident signs of recovery, in both organs, such as proliferation and rearrangements in pseudostratified endothelium and the stereocilia along with convincing recovery in micrometric parameters were observed in Pb-J group.

CONCLUSION

The results indicate that epididymis and vas deferens are highly sensitive to Pb exposure while Jambul pulp extract has shown rich mitigating potentials against such histopathologies.

摘要

背景

像蒲桃这样的珍贵水果被忽视和浪费,而像铅摄入这样的环境污染物却仍未得到重视。

目的

本研究旨在探讨蒲桃果肉提取物对小鼠附睾和输精管假复层上皮及静纤毛中铅有害作用的影响。

材料与方法

将30只年轻雄性小鼠(小家鼠)随机分为3组(n = 10),即对照组、铅组(Pb)和铅 - 蒲桃组(Pb - J)。铅组和铅 - 蒲桃组在15天内随意饮用含50ppm铅的水,接下来5天饮用无铅水。铅 - 蒲桃组每12小时给予0.2ml蒲桃果肉提取物。对照组不进行任何处理。在安乐死后第21天取出器官(附睾和输精管)。最后对这些器官进行组织学和微观测量研究。

结果

铅组的两个器官均出现明显的组织学和微观测量变化。这些变化包括附睾头和附睾尾折叠管的横截面积显著(P≤0.05)减小,以及其内皮厚度明显改变。与对照组相比,铅组假复层内皮出现明显的凋亡迹象(空泡化),附睾和输精管的静纤毛遭到破坏。在铅 - 蒲桃组中,两个器官均出现明显的恢复迹象,如假复层内皮和静纤毛的增殖和重新排列,以及微观测量参数令人信服的恢复。

结论

结果表明附睾和输精管对铅暴露高度敏感,而蒲桃果肉提取物对这种组织病理学表现出丰富的缓解潜力。
