本文研究了注射锡、铅的小鼠一次、二次免疫应答。作者将6周龄dd系雄性小鼠370只,分为3组:对照组用pH4的无离子水;锡组用氯化亚锡(SnCl_2)1.67微克分子/公斤·天,连续3天;铅组用氯化铅(PbCl_2)5微克分子/公斤·天,连续2天,备以0.1毫升/10克·体重腹腔注射。注射后第2天、第7天腹腔注射羊红血球6.6×10~7个细胞/克·体重,进行2次抗原刺激。每次抗原刺激后,隔日从各组中取10～13只小鼠摘除脾脏及采
This article studies the tin and lead injection of mice primary and secondary immune response. The authors divided 370 6-week-old dd male mice into three groups: control group with no ion water at pH4; tin group with 1.67 μg / kg · day stannous chloride for three days; Group with lead chloride (PbCl 2) 5 micrograms per kilogram · day for 2 days, prepared with 0.1 ml / 10 g body weight intraperitoneal injection. On day 2 and day 7 after injection, sheep erythrocytes were intraperitoneally injected with 6.6 × 10 ~ 7 cells / g body weight, and antigen stimulation was performed twice. After each antigen challenge, 10 to 13 mice from each group were taken every other day for removal of the spleen and harvesting
