Özet

Isoniazid and rifampicin (IRC) have been shown to cause hepatotoxicity in both clinical and preclinical studies. Oxidative stress and inflammation have been held responsible for the pathogenesis of IRC-induced hepatotoxicity. Antioxidative and anti-inflammatory effects of thiamine pyrophosphate (TPP) and cinnamon extract (CE) have been shown in previous studies. Therefore, our study investigated the protective effects of TPP and CE on possible liver damage caused by IRC treatment in rats. Twenty-four albino Wistar rats were categorized into four groups: a healthy group (HG), an IRC group (IRG), a TPP+IRC group (TIRG), and a CE+IRC group (CIRG). TPP (25 mg/kg) was administered intraperitoneally to TIRG, while CE (100 mg/kg) was administered orally to CIRG. In IRG, TIRG, and CIRG, isoniazid (50 mg/ kg) and rifampicin (50 mg/kg) were administered orally one hour after these treatments. For seven days, this procedure was repeated once a day. After this period, blood samples were taken from the tail veins, and the rats were sacrificed. The removed liver tissues were analyzed for oxidant, antioxidant, and proinflammatory cytokines and subjected to histopathological evaluation.
