We aimed to investigate the protective role of thymoquinone (TQ) by targeting its antiapoptotic and antioxidant properties against kidney damage induced by arsenic in rats. We have used the 24 male Sprague-Dawley rats. Rats were divided into three groups. Physiological serum in 10 mL/kg dose as intragastric was given to the control group. Sodium arsenite (10 mg/kg, intragastric by gavage for fifteen days) was given to the arsenic group. Sodium arsenite (10 mg/kg, intragastric by gavage for fifteen days) and TQ (10 mg/kg, intragastric by gavage for 15 days) was givento the arsenic + TQ group. After 15 days, the animals' kidneys were taken theirs, then we have performed histological and apoptotic assessment. Superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GSH-Px) enzyme activities and malondialdehyde (MDA) levels have examined as the oxidative stress parameters. We have determined the levels of arsenic. Increased renal injury and apoptotic cells have been detected in the arsenic group. Degenerative changes in the arsenic + TQ group were diminished. Although the MDA levels were augmented in the arsenic group, SOD, CAT and GSH-Pxenzyme activities were lessened than the other groups. Our findings suggest that TQ may impede the oxidative stress, the cells have been damaged and also the generation of apoptotic cells arisen from arsenic. TQ plays a protective role against arsenic-induced toxicity in kidney and may potentially be used as a remedial agent.
