Background:
Lead (Pb) is a metal that affects many body systems, primarily the male reproductive system. This study aimed to examine the phytochemical profiling and beneficial effects of Juglans regia oil (JRO) in alleviating lead-induced reprotoxicity-associated oxidative injury in rats. Adult male Wistar rats were randomly divided into four groups as follows: control group received no treatment, Pb group was exposed to 0.344 g kg-1 bw of Pb acetate, Pb + JRO group was co-treated with Pb plus walnut oil (0.9 g kg-1 bw) and JRO group received walnut oil only.
Results:
Pb-treated rats showed significantly decreased gonado-somatic index, count and viability of sperm. Testosterone levels decreased in Pb-treated animals. Besides, Pb disrupted the oxidative/antioxidative status, the plasmatic lipase activity and testicular Pb content. Furthermore, Pb produced testis histopathological features, especially cell degeneration, atrophy and tubular disarrangement. Co-treatment with JRO was found to be effective for recovering the increased testicular oxidative damage-associated histological features in the Pb group. This was supported by the in silico modeling results.
Conclusion:
The in silico analyses revealed that JRO compounds bound androgen receptor and RAC-alpha serine/threonine kinase with high affinities, which together with pharmacokinetic properties and molecular interactions satisfactorily support the beneficial in vivo findings in the Pb + JRO group of rats. © 2024 Society of Chemical Industry.
