近年来国内外对于旧结核菌素(以下简称O.T)试验有些新的认识,通过O.T复强作用(Boosting effect)的研究证明,人体在结核菌感染后,有部份已致敏机体经过一定时间后,O.T的变态反应减弱或消失,此时如再次进行O.T试验可使变态反应复强。本文根据O.T试验的复强作用,在1978年7月石河子市儿童健康普查中,应用O.T试验调查结核自然感染率的14岁以下儿童1014人,对其中889人于一周后进行相同剂量不同部位的O.T复试,对比观察O.T的复强反应情况。现将有关资料综合整理并结合文献加以讨论。一.调查对象和方法:
In recent years, there are some new understandings about the old tuberculin (OT) test at home and abroad. The study by the Boosting effect proves that after the Mycobacterium tuberculosis infection, some people have sensitized the body after a certain period of time After the OT metamorphosis weakened or disappeared, this time as OT test can make allergic re-energization.
