本文用“肿瘤抑制率”为指标,观察亚硒酸钠对艾氏腹水癌(实体型)生长的抑制作用。3个实验组小鼠腹腔注射亚硒酸钠,剂量分别为1/7LD_(50)(3.50mg/kg体重)、1/10LD_(50)(2.45mg/kg体重)和1/30LD_(50)(0.82mg/kg体重)每日给药1次,共7天。结果以1/10LD_(50)组的“肿瘤抑制率”为最高,经体重校正瘤重后,“肿瘤抑制率”仍高达35.59％。 This article used “tumor inhibition rate” as an indicator to observe the inhibitory effect of sodium selenite on Ehrlich ascites carcinoma (solid type) growth. Three experimental mice were intraperitoneally injected with sodium selenite in doses of 1/7LD 50 (3.50 mg/kg body weight), 1/10 LD 50 (2.45 mg/kg body weight) and 1/30LD 50 (0.82 mg/kg body weight) was administered once daily for 7 days. Results The “tumor inhibition rate” of the 1/10 LD_(50) group was the highest. After weight-corrected tumor weight, the “tumor inhibition rate” was still as high as 35.59%.
