摘要 AIM: To investigate the effects of Reishi mushroom, Ganoderma lucidum extract (GLE), on liver fibrosis induced by carbon tetrachloride (CCl4) in rats. METHODS: Rat hepatic fibrosis was induced by CCl4. Forty Wistar rats were divided randomly into 4 groups: control, CCl4, and two GLE groups. Except for rats in control group, all rats were administered orally with CCl4 (20%, 0.2 mL/100 g body weight) twice a week for 8 weeks. Rats in GLE groups were treated daily with GLE (1 600 or 600 mg/kg) via gastrogavage throughout the whole experimental period. Liver function parameters, such as ALT, AST, albumin, and albumin/globulin (A/G) ratio, spleen weight and hepatic amounts of protein, malondiladehyde (MDA) and hydroxyproline (HP) were determined. Histochemical staining of Sirius red was performed. Expression of transforming growth factor β1 (TGF-β1), methionine adenosyltransferase (MAT1) 1A and MAT2A mRNA were detected by using RT-PCR. RESULTS: CCl4 caused liver fibrosis, featuring increase in plasma transaminases, hepatic MDA and HP contents, and spleen weight; and decrease in plasma albumin, A/G ratio and hepatic protein level. Compared with CCl4 group, GLE (600, 1 600 mg/kg) treatment significantly increased plasma albumin level and A/G ratio (P〈0.05) and reduced the hepatic HP content (P〈0.01). GLE (1 600 mg/kg) treatment markedly decreased the activities of transaminases (P〈 0.05), spleen weight (P〈 0.05) and hepatic MDA content (P〈0.05); but increased hepatic protein level (P〈0.05). Liver histology in the GLE (1 600 mg/kg)-treated rats was also improved (P〈0.01). RT-PCR analysis showed that GLE treatment decreased the expression of TGF-β1 (P〈 0.05-0.001) and changed the expression of MAT1A (P〈0.05-0.01) and MAT2A (P〈 0.05-0.001). CONCLUSION: Oral administration of GLE significantly reduces CCl4-induced hepatic fibrosis in rats, probably by exerting a protective effect against hepatocellular ne 瞄准:调查 Reishi 蘑菇的效果, Ganoderma 易懂嗯摘录(GLE ) ,在肝上,纤维变性在老鼠由四氯化碳(CCl4 ) 导致了。方法:老鼠肝的纤维变性被 CCl4 导致。四十只 Wistar 老鼠随机被划分成 4 个组:控制, CCl4,和二个 GLE 组。除了在控制组的老鼠,所有老鼠与 CCl4 口头上地被管理(20% , 0.2 mL/100 g 体重) 两次为 8 个星期的一个星期。在 GLE 组的老鼠每天在整个整个试验性的时期经由胃管饲法与 GLE (1,600 或 600 mg/kg ) 被对待。肝功能参数 malondiladehyde (MDA ) 和羟脯氨酸(HP ) 例如中高音,著名计算机生产厂商,白朊,和白朊 / 血球素(A/G ) 比率,怒气重量和蛋白质的肝的数量,被决定。天狼星红的组织化学的染色被执行。转变生长因素 beta1 (TGF-beta1 ) 的表示,蛋氨酸 adenosyltransferase (MAT1 ) 1A 和 MAT2A mRNA 被使用 RT-PCR 检测。结果:CCl4 引起了肝纤维变性,展示血浆 transaminases,肝的 MDA 和 HP 内容,和怒气重量的增加;并且在血浆白蛋白, A/G 比率和肝的蛋白质的减少铺平。与 CCl4 组相比, GLE (600, 1,600 mg/kg ) 处理显著地增加了血浆白蛋白水平和 A/G 比率(P < 0.05 ) 并且减少了肝的 HP 内容(P < 0.01 ) 。GLE (1,600 mg/kg ) 治疗显著地减少了 transaminases 的活动(P < 0.05 ) ,脾重量(P < 0.05 ) 并且肝的 MDA 内容(P < 0.05 ) ;但是增加了肝的蛋白质水平(P < 0.05 ) 。在 GLE (1,600 mg/kg ) 的肝组织学对待老鼠也被改进(P < 0.01 ) 。RT-PCR 分析证明 GLE 处理减少了 TGF-beta1 (P < 0.05-0.001 ) 的表示并且改变了 MAT1A (P < 0.05-0.01 ) 和 MAT2A (P < 0.05-0.001 ) 的表示。结论:GLE 的口服显著地在老鼠减少导致 CCl4 的肝的纤维变性,可能由由它的免费激进分子的清除能力对肝细胞坏死施加保护的效果。
