| 摘 要： | ~(211)At标记的抗人胃癌单克隆抗体3H_(11)对裸小鼠人胃癌移植瘤的生长在短期内有明显抑制作用。治疗后第9天药物对人胃癌生长的抑制作用最为明显~(211)At—3H_(11)(5μCi/只)对人胃癌的抑制率:尾静脉给药为80％,胃癌移植瘤内给药为93％,相同剂量的离子型~(211)At尾静脉给药对胃癌的抑制率为48％.第20天处死动物时~(211)At—3H_(11)尾静脉和肿瘤内给药的抑制率分别是66％和81％,离子型~(211)At尾静脉给药的抑制率为6％,抑制作用明显下降。

| Abstract: | In short time, 211 - At labelled monoclonal antibody 3H11 inhibited the growth of human gastric cancer grafted in nude mice effectively. The most evident inhibition was observed at the 9th day after treatment, and the tumor inhibition rates were 80%, 93%, 48% in the groups of intravenous injection , internal tumor injection ( both 211 At - 3 H11 5 uCi per animal ) , Na 211At (5uCi per animal)treatment respectively. On the 20th day,when animals were killed,the tumor imbibition rates were 66% ,81% ,6%,respectively. Inhibition treated with Na211At showed obviously lower than those at the 9th day . |
