Özet

Isoniazid (INH) is among the most important anti-tuberculosis agents widely prescribed. However, its clinical use is restricted due to its severe side effects associated with neurotoxicity. The aim of the present study was to investigate the neuroprotective effects of chrysin (CR), a natural antioxidant, against INH-induced neurotoxicity in rats. The rats were treated orally with INH (400 mg/kg body weight) alone or with CR (25 and 50 mg/kg body weight) for 7 consecutive days. INH administration significantly increased brain lipid peroxidation and resulted in a significant decrease in antioxidant biomarkers including superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPx) and glutathione (GSH). INH treatment also increased levels of nuclear factor kappa B (NF-kappa B), tumor necrosis factor-alpha (TNF-alpha), glial fibrillary acidic protein (GFAP) and activities of p38 alpha mitogen-activated protein kinase (p38 alpha MAPK) while decreasing levels of neural cell adhesion molecule (NCAM). Double immunofluorescence expressions of c-Jun N-terminal kinase (JNK) and Bcl-2 associated X protein (Bax) in brain tissues were increased after INH administration. Furthermore, INH increased mRNA expression levels of nuclear factor erythroid 2-related factor 2 (Nrf-2), heme oxygenase-1 (HO-1), NAD(P)H: quinone oxidoreductase 1 (NQO1), glutamate-cysteine ligase modifier subunit (Gclm), glutamate cysteine ligase catalytic subunit (Gclc), NF-kappa B, TNF-alpha, interleukin-1 beta (IL-1 beta), interleukin-6 (IL-6) and GFAP in rat brain tissues. Co-treatment with CR increased anti-oxidant capacity as well as regulated inflammation and apoptosis in brain. Additionally, molecular docking results showed that CR had the potential to interact with the active sites of TNF-alpha and NF kappa-B. In conclusion, CR improved INH-induced brain oxidative damage, inflammation and apoptosis, possibly through their antioxidant properties.
