摘要:
用四氯化碳导致小鼠肝损伤,各组每日灌胃不同剂量螺旋藻,检测了饲养45d的小鼠血清的ALT活力、肝组织的SOD活力和MDA含量,分别建立ALT、SOD活力以及MDA含量随剂量(C)变化的函数,求出各项临界参数值,并对参数的生物学意义进行解释,以观察螺旋藻对肝损伤小鼠肝组织中SOD活力和MDA的影响.实验结果显示:螺旋藻能提高小鼠SOD的活力并降低其MDA含量,进一步验证了螺旋藻可提高肝损伤小鼠肝组织的抗氧化能力,分析结果还显示螺旋藻对肝组织抗氧化能力的提高既具有一定的量效累积性,也存在量效局限性.

Abstract:
In this experiment, CCL4 was used to induce liver injury in mice.Different dosages of Spirulina are given in each group respectively for 45d.ALT activity in serum, SOD activity and MDA content in the mice's brain were assayed, the functions between the dosage of Spirulina (C) and ALT, SOD, MDA values were formed with statistical methods.Relative critical values were calculated according to these functions and their biological meanings were explained.The results show that Spirulina can reduce ALT activity, improve SOD activity and reduce MDA content, and when the dosage of Spirulina overruns a certain value, the antioxidant ability of Spirulina is reduced.The spe< ifir parameters are as follows, the niininuini effectual dosage to decrease AIT is 106.4mg/kg;and that of MDA is 121.3mg/kg, the maximum dosage to increase SOD is 385.3mg/kg.It proves that Spirulina can enhance the antioxidant ability of liver in mice and alleviate liver injury caused by CCL4
Key words:  Spirulina  chronic liver injuiy  ALT  SOD  MDA
