Abstract


Background: Malathion is one of organophosphate pesticides that is widely used in agriculture and crops to control insects. Malathion affects body organs such as the reproductive system by inhibiting acetylcholinesterase activity and induction of oxidative stress. This study is aimed to investigate the effects of malathion on glutathione (GSH) and malondialdehyde (MDA) level in testis of male rats, as well as to study the protective role of Ascorbic Acid.

Methods: In this study, 30 adult male Wistar rats weighing approximately 200–250 g were divided into 5 groups of 6 rats each. These groups include a control group (no intervention), sham (normal saline 0.9%), experimental Group 1 (malathion 50 mg/kg), experimental Group 2 (Malathion 50 mg/kg + Ascorbic Acid 200 mg/kg), and experimental Group 3 (Ascorbic Acid 200 mg/kg). Malathion, solvents, and
ascorbic acid were injected intraperitoneally. After 6 weeks, all groups were anesthetized, and the right testis was used to measure levels of MDA and GSH. MDA as a marker of lipid peroxidation and GSH content was used.

Results: The results showed that malathion increased MDA level and decreased GSH level compared with the control group (P < 0.001). It was also found that administration of malathion in combination with ascorbic acid reduced MDA level and increased the GSH level.

Conclusions: Malathion‑induced lipid peroxidation and oxidative stress in the testis of rats. In addition, it seems that ascorbic acid, due to its antioxidant capabilities, can improve malathion‑induced poisonous changes.
