It seems that gentamicin's toxicity to the liver is caused by reactive oxygen species production. The antioxidant and anti-inflammatory properties of extract (AN) have been demonstrated in recent studies. This research focused on how AN's extract affected gentamicin-induced liver damage in rats. Twenty-four Wister rats of male type were divided into four groups: first group received saline as a control, second group received AN (5%) for fifteen days, group three received daily intraperitoneal injections of gentamicin (100 mg/kg) for fifteen days, and group four, as mentioned in groups 2 and 3, also received gentamicin injections and AN extraction (5%) for fifteen days. In order to conduct biochemical analysis, serum was extracted. Histopathology, immunohistochemistry analyses for hepatic toxicity were all performed on the collected tissue samples. Serum levels of ALT, AST, total bilirubin, and GGT were all elevated after using gentamicin. The inflammatory cytokines)IL-1, TNF-α and IL-6(, all were increased in gentamycin-injected group. There were showing deformity of bile duct, hepatocellular necrosis and infiltration of inflammatory cells congestion of portal vein, and hepatic sinusoids besides fibrosis of portal area (white arrows), hypertrophy in gentamycin-injected group compared to AN plus gentamycin administered rats. There were upregulation in the immunoreactivity of COX-2, IFNB and TGF-beta1 (TGF-β1) in gentamycin intoxicated rats. When gentamicin and AN were administered together, hepatic biomarkers, inflammatory cytokines, histological, and immunohistochemical markers were all ameliorated by AN administration.
庆大霉素对肝脏的毒性似乎是由活性氧的产生引起的。提取物(AN)的抗氧化和抗炎特性已在最近的研究中得到证实。本研究聚焦于AN提取物如何影响庆大霉素诱导的大鼠肝损伤。将24只雄性Wister大鼠分为四组:第一组接受生理盐水作为对照,第二组接受AN(5%),持续15天,第三组每天腹腔注射庆大霉素(100mg/kg),持续15天,第四组,如第2组和第3组所述,也接受庆大霉素注射和AN提取物(5%),持续15天。为了进行生化分析,提取血清。对收集的组织样本进行肝毒性的组织病理学、免疫组织化学分析。使用庆大霉素后,血清中的谷丙转氨酶(ALT)、谷草转氨酶(AST)、总胆红素和γ-谷氨酰转肽酶(GGT)水平均升高。注射庆大霉素的组中,炎性细胞因子(白细胞介素-1、肿瘤坏死因子-α和白细胞介素-6)均增加。与AN加庆大霉素给药的大鼠相比,注射庆大霉素的组出现胆管畸形、肝细胞坏死、炎性细胞浸润、门静脉充血和肝血窦,此外还有门管区纤维化(白色箭头)、肥大。庆大霉素中毒大鼠中环氧合酶-2(COX-2)、干扰素-β(IFNB)和转化生长因子-β1(TGF-β1)的免疫反应性上调。当同时给予庆大霉素和AN时,AN给药可改善肝脏生物标志物、炎性细胞因子、组织学和免疫组织化学标志物。
