Liver disorders are one of the principal reasons for mortality in the world. Isotretinoin is a systemic retinoid that has been approved for therapy of acne vulgaris since 1982. This drug causes complications in the body. Evidence suggests that Isotretinoin might cause hepatotoxicity. Our research aimed to study the exact mechanism of hepatotoxicity induced by isotretinoin and the protective role of taurine in this toxicity. Biomarkers such as aspartate transaminase (AST) and alanine transaminase (ALT), superoxide dismutase, glutathione content (GSH), catalase, and malondialdehyde (MDA) were examined. Furthermore, pathological changes were evaluated. The results showed that oral administration of Isotretinoin induced hepatotoxicity as showed by elevation in ALT, AST, and MDA; also, it reduced intracellular GSH in rat liver tissue. Administration of taurine prevented the hepatotoxicity induced by isotretinoin in rats significantly.
肝脏疾病是世界范围内主要的致死原因之一。异维 A 酸是一种全身性维 A 酸类药物,自 1982 年以来被批准用于治疗寻常痤疮。该药物会引起身体的并发症。有证据表明,异维 A 酸可能会引起肝毒性。我们的研究旨在研究异维 A 酸引起肝毒性的确切机制以及牛磺酸在这种毒性中的保护作用。我们检测了天冬氨酸转氨酶(AST)和丙氨酸转氨酶(ALT)、超氧化物歧化酶、谷胱甘肽含量(GSH)、过氧化氢酶和丙二醛(MDA)等生物标志物。此外,还评估了病理变化。结果表明,异维 A 酸口服给药可导致肝毒性,表现为 ALT、AST 和 MDA 升高;同时,它还降低了大鼠肝组织内的细胞内 GSH。牛磺酸的给药可显著预防大鼠异维 A 酸引起的肝毒性。
