The lymphocyte delayed hypersensitivity response to phytohaemagglutinin (PHA) and hepatitis B antigen (HBsAG) was evaluated by two in vitro tests-leucocyte migration inhibition and DNA synthesis. Patients convalescing from HBsAG-positive hepatits showed the presence of a state of cell-mediated immune responsiveness to the antigen. In Indian childhood cirrhosis, there was a failure of response to HBsAG and a slight but significant depression of reaction to PHA. It is suggested that the lack of immune reactivity to HBsAG, perhaps determined genetically, may be a significant factor in the evolution of cirrhosis in Indian children.
通过白细胞游走抑制和DNA合成这两项体外试验,对淋巴细胞对植物血凝素(PHA)和乙肝抗原(HBsAG)的迟发型超敏反应进行了评估。从HBsAG阳性肝炎中康复的患者表现出对该抗原的细胞介导免疫反应状态。在印度儿童肝硬化中,对HBsAG无反应,对PHA的反应有轻微但显著的降低。有人提出,对HBsAG缺乏免疫反应性,可能由基因决定,可能是印度儿童肝硬化发展中的一个重要因素。
