    Thymoquinone Ameliorate Hepatorenal Toxicity Associated with Propylthiouracil-Induced Hypothyroidism in Juvenile Rats

    Acta Endo (Buc) 2021 17(4): 432-439 doi: 10.4183/aeb.2022.432

    Background. An increasing number of studies suggest that hypothyroidism may lead to hepatorenal toxicity. This study examined whether thymoquinone (TQ), the main active Nigella sativa constituent, could prevent the detrimental influences of hepatorenal toxicity of hypothyroidism during the juvenile period in rats. Methods. The male rats were randomly divided into four groups (n = 7), including control, propylthiouracil (PTU), PTU-TQ 5 mg/kg, and PTU-TQ 10 mg/kg. PTU was dissolved in drinking water at a concentration of 0.05% and administered for six weeks. In the PTU-TQ5 and PTU-TQ10 groups, animals received PTU plus 5 mg/kg and 10 mg/kg of the TQ (i.p.) for six weeks, respectively. The rats were evaluated after TQ treatment by measuring serum markers of liver and kidney function tests as well as oxidative stress biomarkers in liver and kidney tissues. Results. Administration of TQ (5 and 10 mg/ kg) decreased oxidative stress damage in liver and kidney tissue in hypothyroidism rats with improvement in activities of antioxidant enzymes and a decrease in MDA in both liver and kidney homogenates. Furthermore, TQ treatment significantly inhibited the elevation of serum biochemical markers of liver and kidney function associated with this hepatorenal toxicity. Conclusion. These results suggest that the protective effect of TQ in hypothyroidism-induced hepatorenal toxicity in rats is attributed to its ability to reduce oxidative stress in hepatic and renal tissues. However, more studies are recommended to investigate the exact mechanism (s) for the effect of TQ on hepatorenal outcomes of hypothyroidism in human subjects.
