This study was to investigate the protective effect of cordycepin-enriched Cordyceps militaris against alcohol-induced hepatotoxicity in Sprague-Dawley rats. Alcohol-feeding rats were fed diets with Paecilomyces japonica as CPJ group, C. militaris as CCM group, cordycepin-enriched C. militaris as CCMα group at the 3% (w/w) level and silymarin at the 0.1% (w/w) level for 4 weeks. Alcohol administration resulted in a significant increase in the activities of aspartate aminotransferase (AST), alanine aminotransferase (ALT), γ-glutamyl transpeptidase (γ-GTP), alkaline phosphatase (ALP), and lactate dehydrogenase (LDH) and the levels of blood alcohol and acetaldehyde in serum. However, CCMα group markedly prevented from alcohol-induced elevation of these parameters in serum. CCMα group showed the increased both hepatic activities of alcohol dehydrogenase (ADH) and acetaldehyde dehydrogenase (ALDH). Unlike the action of alcohol treatment on alcoholic fatty liver, CCMα group was also attenuated lipid droplet accumulation in the hepatocytes. Present study was also confirmed the beneficial roles of silymarin (hepatoprotective agent) against alcohol-induced liver injury in rats. Therefore, cordycepin-enriched C. militaris can be a promising candidate to prevent from alcohol-induced hepatotoxicity.
本研究旨在探讨蛹虫草中虫草素富集物对酒精诱导的 Sprague-Dawley 大鼠肝毒性的保护作用。酒精喂养的大鼠以日本被毛孢(Paecilomyces japonica)作为 CPJ 组、蛹虫草(Cordyceps militaris)作为 CCM 组、虫草素富集蛹虫草(Cordyceps militaris)作为 CCMα组,分别以 3%(w/w)和 0.1%(w/w)的水平添加,以及水飞蓟素(silymarin)作为阳性对照组,连续喂养 4 周。酒精摄入导致血清中天冬氨酸氨基转移酶(AST)、丙氨酸氨基转移酶(ALT)、γ-谷氨酰转肽酶(γ-GTP)、碱性磷酸酶(ALP)和乳酸脱氢酶(LDH)的活性以及血中酒精和乙醛的水平显著升高。然而,CCMα组明显阻止了酒精引起的这些参数在血清中的升高。CCMα组同时增加了肝中酒精脱氢酶(ADH)和乙醛脱氢酶(ALDH)的活性。与酒精处理对酒精性脂肪肝的作用不同,CCMα组还减轻了肝细胞中脂滴的积累。本研究还证实了水飞蓟素(一种保肝剂)对大鼠酒精性肝损伤的有益作用。因此,虫草素富集蛹虫草可以成为预防酒精性肝毒性的一种有前途的候选物。
