本文报道三例肝移植术后乙型肝炎病毒(HBV)抗原抗体系统(抗HBc、抗HBe、HBsAg、HBcAg),甲胎蛋白(AFP),E活性花环OTLMIT,总补体,C_3等指标动态观察资料。结果发现术后初期,虽然大量使用免疫抑制药,受者仍处在免疫排斥的应激状态,排斥反应不断发生,细胞免疫功能也处在近似正常水平。这时HBsAg转为阴性,AFP逐渐下降接近正常。随后因长期使用免疫抑制药,机 This article reports the dynamic observation of three anti-HBs, anti-HBe, HBsAg, AFP, OTLMIT, total complement and C_3 markers in three cases of liver transplantation after liver transplantation data. The results showed that although the immunosuppressive drugs were widely used in the early postoperative period, the recipients were still in the state of immune rejection and the rejection occurred constantly. The cellular immune function was also at a nearly normal level. When HBsAg turned negative, AFP gradually decreased to near normal. Then because of long-term use of immunosuppressive drugs, machine
