Non alcoholic steatohepatitis (NASH), severe form of diseases belonging to the spectrum of the Non alcoholic fatty liver disease (NAFLD). It is an asymptomatic disease which leads to fibrosis and finally to cirrhosis, an end stage liver disease.
To study the effect of pioglitazone, quercetin and hydroxy citric acid on hepatic biomarkers and various biochemical parameters in experimentally induced non alcoholic steatohepatitis (NASH).
Male Wister rats were divided into 8 groups. The activities of alkaline phosphatase (ALP), aspartate transaminase (AST), alanine transaminase (ALT), lactate dehydrogenase (LDH) and γ-Glutamyl Transferase (GGT) were assayed in serum. The levels of various other biochemical parameters such as serum albumin, total bilirubin, creatinine, urea, uric acid and glucose were also estimated in experimental NASH.
The NASH group produced severe liver injury by significantly increasing the serum levels of ALT, AST, GGT and LDH compared with that of the control. However, the experimental NASH rats treated with pioglitazone, with quercetin and with hydroxy citric acid showed an obvious decrease in ALT, AST, GGT and LDH levels when compared with that of NASH induced group. A significant increase in the levels of albumin, creatinine, urea, uric acid, glucose and total bilirubin was noticed in experimentally induced NASH group (group 2) when compared to rats in control group (group 1).
It could be inferred from this study that, pioglitazone, quercetin and hydroxy citric acid may afford protection to the liver against NASH, as evidenced by the results of this study on the levels of various biochemical parameters such as glucose, urea, uric acid, creatinine and bilirubin. Whereas from the results of hepatic marker enzymes, it is evident that optimal protection was observed after quercetin treatment against experimental NASH whereas pioglitazone and hydroxy citric acid also confers protection to some extent against NASH.
非酒精性脂肪性肝炎(NASH)是属于非酒精性脂肪性肝病(NAFLD)谱系的严重疾病形式。它是一种无症状疾病,会导致纤维化并最终发展为肝硬化,即终末期肝病。
研究吡格列酮、槲皮素和羟基柠檬酸对实验性诱导的非酒精性脂肪性肝炎(NASH)中肝脏生物标志物和各种生化参数的影响。
将雄性Wistar大鼠分为8组。测定血清中碱性磷酸酶(ALP)、天冬氨酸转氨酶(AST)、丙氨酸转氨酶(ALT)、乳酸脱氢酶(LDH)和γ-谷氨酰转移酶(GGT)的活性。还对实验性NASH中的各种其他生化参数水平进行了评估,如血清白蛋白、总胆红素、肌酐、尿素、尿酸和葡萄糖。
与对照组相比,NASH组通过显著提高血清中ALT、AST、GGT和LDH水平而造成严重肝损伤。然而,与NASH诱导组相比,用吡格列酮、槲皮素和羟基柠檬酸治疗的实验性NASH大鼠的ALT、AST、GGT和LDH水平明显降低。与对照组(第1组)大鼠相比,实验性诱导的NASH组(第2组)中白蛋白、肌酐、尿素、尿酸、葡萄糖和总胆红素水平显著升高。
从本研究可以推断,吡格列酮、槲皮素和羟基柠檬酸可能对肝脏起到保护作用,使其免受NASH侵害,本研究关于葡萄糖、尿素、尿酸、肌酐和胆红素等各种生化参数水平的结果证明了这一点。而从肝脏标志物酶的结果来看,很明显槲皮素治疗后对实验性NASH观察到了最佳保护作用,而吡格列酮和羟基柠檬酸也在一定程度上对NASH起到保护作用。
