adj.致死的；致命的
Eight strains showed lethiferous activity and eight showed cytotoxicity.Conclusion The results indicated that a... 結(jié)論實驗結(jié)果表明,海藻真菌是尋找抗腫瘤活性物質(zhì)的重要資源。
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:分別測定治療劑量、中毒劑量、致死劑量組小鼠在用藥一段時間后的肝腎功能,并進行組織病理學(xué)檢查。
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. 方法從樣品中選擇性分離得到真菌,并采用海蝦生物致死法和人體慢性髓性白血病細胞K562為篩選模型對所得真菌的發(fā)酵產(chǎn)物進行抗腫瘤活性篩選。
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. 將實驗小鼠（幼年）分成8組，其中治療劑量3組，中毒劑量3組，致死劑量2組，每組10只，雌雄各半。
