Method Hepatic and renal functions,and tissue biopsy were measured in rats with therapeutic,toxic and lethiferous dose treatment after a period of time. 方法:分别测定治疗剂量、中毒剂量、致死剂量组小鼠在用药一段时间后的肝肾功能,并进行组织病理学检查。
Methods Selective isolation of algicolous fungi from algae was done,and antitumor activity corresponds to their lethiferous effect on brine shrimp and cytotoxicity against K562 cell was determined. 方法从样品中选择性分离得到真菌,并采用海虾生物致死法和人体慢性髓性白血病细胞K562为筛选模型对所得真菌的发酵产物进行抗肿瘤活性筛选。
Take the experimental rats into 8 groups including 3 groups for therapeutic dose,3 groups for toxic dose and 2 groups for lethiferous dose, with 10 rats for each group and male and female for half. 将实验小鼠（幼年）分成8组，其中治疗剂量3组，中毒剂量3组，致死剂量2组，每组10只，雌雄各半。
