1 本文分析了2,191名1963年大学新生的结素反应情况:呈阴性反应者874人(39.9％),阳性反应者1,317人(60.1％);阳性反应中女性比男性高10％左右,大城市比中等城市高8.1％,比农村高22.1％。 2.在结素阳性反应的人群中,5～8毫米反应的占阳性反应的37％,其余为9毫米及以上。大城市、中等城市同农村的反应差别主要表现在阴性和9毫米以上之间,3个地区5～8毫米的数字彼此接近。 3.对引起<9毫米反应的因素,和以>9毫米的反应数字来代表自然感染情况问题做了一些初步的探讨。作者认为引起<9毫米的反应的因素与接种卡介苗有关,而极大部分>9毫米的反应是自然感染的结果。
1 This paper analyzes the nidin response of 2,191 freshmen in 1963: 874 (39.9%) were negative and 1,317 (60.1%) were positive; female was 10% more positive than male in the positive reaction, 8.1% higher than medium-sized cities and 22.1% higher than in rural areas. In the nodules positive reaction population, 5 ~ 8 mm reaction accounted for 37% of the positive reaction, the rest is 9 mm and above. Large cities, medium-sized cities with rural differences in response mainly in the negative and 9 mm above the 3 areas of 5-8 mm figures close to each other. 3. Some preliminary discussions are made on the factors that cause the <9mm reaction and on how the natural infection is represented by> 9mm response numbers. The authors conclude that the factors responsible for the <9 mm response are related to the BCG vaccination, whereas a very large fraction> 9 mm is the result of natural infection.
