Ginseng essence (GE) is a formulation comprising four medicinal and edible herbs including ginseng (), American ginseng (), lotus seed (), and lily bulb (). This study was aimed at investigating the hepatoprotective effect of GE against carbon tetrachloride (CCl)-induced liver injury in rats.
We treated Wistar rats daily with low, medium, and high [0.625 g/kg body weight (bw), 1.25 g/kg bw, and 3.125 g/kg bw, respectively] doses of GE for 9 wk. After the 1 wk of treatment, rats were administered 20% CCl (1.5 mL/kg bw) two times a week to induce liver damage until the treatment ended.
Serum biochemical analysis indicated that GE ameliorated the elevation of aspartate aminotransferase and alanine aminotransferase and albumin decline in CCl-treated rats. Moreover, CCl-induced accumulation of hepatic total cholesterol and triglyceride was inhibited. The hepatoprotective effects of GE involved enhancing the hepatic antioxidant defense system including glutathione, glutathione peroxidase, glutathione reductase, glutathione -transferase, superoxide dismutase, and catalase. In addition, histological analysis using hematoxylin and eosin and Masson's trichrome staining showed that GE inhibited CCl-induced hepatic inflammation and fibrosis. Furthermore, immunohistochemical staining of alpha-smooth muscle actin indicated that CCl-triggered activation of hepatic stellate cells was reduced.
These findings demonstrate that GE improves CCl-induced liver inflammation and fibrosis by attenuating oxidative stress. Therefore, GE could be a promising hepatoprotective herbal formulation for future development of phytotherapy.
人参精华(GE)是一种由人参()、西洋参()、莲子()和百合鳞茎()四种药食两用草药组成的配方。本研究旨在探讨GE对四氯化碳(CCl)诱导的大鼠肝损伤的保肝作用。
我们每天用低、中、高剂量[分别为0.625克/千克体重(bw)、1.25克/千克bw和3.125克/千克bw]的GE处理Wistar大鼠,持续9周。在处理1周后,每周给大鼠两次20% CCl(1.5毫升/千克bw)以诱导肝损伤,直至处理结束。
血清生化分析表明,GE改善了CCl处理大鼠中天冬氨酸转氨酶和丙氨酸转氨酶的升高以及白蛋白的下降。此外,CCl诱导的肝脏总胆固醇和甘油三酯的积累受到抑制。GE的保肝作用包括增强肝脏抗氧化防御系统,包括谷胱甘肽、谷胱甘肽过氧化物酶、谷胱甘肽还原酶、谷胱甘肽-S-转移酶、超氧化物歧化酶和过氧化氢酶。此外,苏木精和伊红染色及Masson三色染色的组织学分析表明,GE抑制了CCl诱导的肝脏炎症和纤维化。此外,α-平滑肌肌动蛋白的免疫组织化学染色表明,CCl触发的肝星状细胞激活减少。
这些发现表明,GE通过减轻氧化应激改善CCl诱导的肝脏炎症和纤维化。因此,GE可能是一种有前途的保肝草药配方,可用于未来植物疗法的开发。
