摘要
本文用不同剂量的β-羧乙基锗倍半氧化物(carboxyethylgermanium sesquioxide,Ge132)100,200,400mg/kg(ⅳ)预防四氯化碳(carbon tetrachloride,CCl_4)所致的小鼠实验性肝损伤。结果表明Ge132可降低肝损伤小鼠的血清谷丙转氨酶(SGTP)及肝甘油三酯,增加肝糖元含量,并减轻肝细胞的变性与坏死。Ge132还可缩短四氯化碳肝损伤小鼠的小戊巴比妥钠的睡眠时间及延长正常小鼠戊巴比妥钠的睡眠时间。此外,Ge132单用或与化疗药物(环磷酰胺)合用均有明显剂量依赖性升高白细胞的作用。
Ge132 possesses immuno-stimulating actions such as IFN-γ induction, NK cell activation, tumor inhibition and life-span prolongation, but its effects on liver injury and white blood cells had rarely been reported. In this paper, various doses of Ge132 (100, 200, 400mg/kg,ⅳ) were used to prevent experimental liver injury induced by carbon tetrachoride (CCl_4) in mice. The results indicated that Ge132 lowered the SGPT level, decreased the accumulation of triglyceride in liver and increased the glycogen content in hepatocytes. Ge132 also shortened the pentobatbital sleeping time in CCl_4, intoxicated mice while prolonged this time in normal mice. Histological examination showed that hepatic degeneration and necrosis in Ge132 pretreated mice were less sever than those in CCl_4group without pretreatment. In addition, our data also showed that Ge132 alone or combined with cyclophosphamide (CY) elevated the white blood cell level significantly in a dose-dependent manner in normal mice.
