报告一处农村全人口结核菌素试验复强反应现象调查。复强反应阳性率为１１．０％。采用ＥＬＩＳＡ测定ＰＰＤ试验的后５组人群血清ＩｇＥ含量，结果：人群血清ＩｇＥ含量随着ＰＰＤ试验次数的增加呈现逐渐升高的趋势。提示结核菌抗原刺激机体，可使其产生大量的ＩｇＥ，Ⅰ型变态反应可能也参与了被结核菌感染机体的感染发病过程。各组ＰＰＤ反应强度与血清ＩｇＥ含量无相关，支持结核菌进入机体，机体免疫呈现细胞免疫与体液免疫发生分离现象的观点。
Report of a rural population of tuberculin test recovery phenomenon survey. The positive rate of complex reaction was 11.0%. Serum IgE levels were measured by ELISA in the last 5 groups of people. The results showed that the serum IgE level increased gradually with the increase of PPD test. Tip Mycobacterium tuberculosis antigen to stimulate the body, can make a large number of IgE, type Ⅰ allergy may also be involved in the process of infection by Mycobacterium tuberculosis infection. There was no correlation between PPD reaction intensity and serum IgE level in each group, which supported the entry of MTB into the body, and the immune system presented the phenomenon of segregation of cellular immunity and humoral immunity.
