Cellular sensitization to rabbit liver specific lipoprotein (RLSP) has been investigated using a lymphocyte transformation test in patients with chronic active hepatitis (CAH). A stimulation index greater than 2 was recorded in twenty out of twenty-five cases (eight of ten HBsAg positive and twelve of fiteen HBsAg negative) while values were lower than 2 in all the normal subjects. These results confirm the finding of sensitization to LSP in chronic active hepatitis irrespective of HBsAg status and show that rabbit LSP can be used as an alternative to the human antigen in the lymphocyte transformation test, and is further evidence that this liver membrane lipoprotein has antigenic determinants which have species-cross-reactivity.
在慢性活动性肝炎(CAH)患者中,已通过淋巴细胞转化试验研究了细胞对兔肝特异性脂蛋白(RLSP)的致敏作用。25例患者中有20例(10例HBsAg阳性患者中的8例以及15例HBsAg阴性患者中的12例)的刺激指数大于2,而所有正常受试者的刺激指数均低于2。这些结果证实了无论HBsAg状态如何,慢性活动性肝炎患者均存在对LSP的致敏现象,表明兔LSP可在淋巴细胞转化试验中用作人类抗原的替代品,进一步证明这种肝细胞膜脂蛋白具有种属交叉反应性的抗原决定簇。
