The effect of oral administration of Phyllanthus methanolic extracts (PME) (i.e. P. acidus, P. emblica, P. myrtifolius, P. multiflorus, P. amarus, P. debilis, P. embergeri, P. hookeri, P. tenellus, P. urinaria L.s. nudicarpus, P. urinaria L.s. urinaria) or gallic acid (GA) on the progression of acute liver damage induced by CCl(4) in rats was examined by morphological and biochemical methods. P. acidus, P. urinaria L.s. urinaria, GA at a dose of 0.5 g/kg, and P. emblica, P. urinaria L.s. nudicarpus at a dose of 1.0 g/kg attenuated CCl(4)-induced increase in serum glutamate-oxalate-transaminase (GOT). P. acidus, P. urinaria L.s. nudicarpus, P. urinaria L.s. urinaria, GA at a dose of 0.5 g/kg, and P. emblica, P. amarus, P. hookeri, P. tenellus at a dose of 1.0 g/kg attenuated CCl(4)-induced increase in serum glutamate-pyruvate-transaminase (GPT). Concurrently, P. acidus, P. multiflorus, P. embergeri, P. hookeri, P. tenellus and P. urinaria L.s. urinaria elevated the activity of liver reduced glutathione peroxidase (GSH-Px). Since the protective effects of P. acidus, P. emblica, P. myrtifolius, P. embergeri, P. urinaria L.s. nudicarpus, P. urinaria L.s. urinaria and GA correlate with a reduction in liver infiltration and focal necrosis observed using histological methods, these data demonstrate that P. acidus and P. urinaria L.s. urinaria are hepatoprotective and antioxidant agents.
采用形态学和生物化学方法,研究了口服叶下珠甲醇提取物(PME)(即酸叶下珠、余甘子、桃叶叶下珠、多花叶下珠、苦味叶下珠、柔弱叶下珠、恩氏叶下珠、胡氏叶下珠、纤细叶下珠、落地生根叶下珠、落地生根叶下珠变种)或没食子酸(GA)对四氯化碳诱导的大鼠急性肝损伤进展的影响。酸叶下珠、落地生根叶下珠变种、剂量为0.5 g/kg的GA以及余甘子、剂量为1.0 g/kg的落地生根叶下珠减轻了四氯化碳诱导的血清谷氨酸草酰乙酸转氨酶(GOT)升高。酸叶下珠、落地生根叶下珠、落地生根叶下珠变种、剂量为0.5 g/kg的GA以及余甘子、苦味叶下珠、胡氏叶下珠、纤细叶下珠、剂量为1.0 g/kg减轻了四氯化碳诱导的血清谷氨酸丙酮酸转氨酶(GPT)升高。同时,酸叶下珠、多花叶下珠、恩氏叶下珠、胡氏叶下珠、纤细叶下珠和落地生根叶下珠变种提高了肝脏还原型谷胱甘肽过氧化物酶(GSH-Px)的活性。由于酸叶下珠、余甘子、桃叶叶下珠、恩氏叶下珠、落地生根叶下珠、落地生根叶下珠变种和GA的保护作用与组织学方法观察到的肝脏浸润和局灶性坏死减少相关,这些数据表明酸叶下珠和落地生根叶下珠变种是肝脏保护剂和抗氧化剂。
