新生鼠及幼鼠的T淋巴细胞一般是未成熟的.新生鼠如果接受大量同种抗原刺激,可对同种皮肤移植产生耐受性.沟口健二等曾以排斥腹水型同种肿瘤细胞的活性为指标,建立了定量测定H-2K/D抗原特异性T细胞性移植免疫强度的方法.本文作者用这种方法进行实验,发现新生鼠及幼鼠对适量的同种抗原有很强的T细胞性移植免疫应答.实验时给BALB/c系新生鼠及幼鼠腹腔内注射(CBA×BALB/c)F_1或者(C3H× Neonatal rats and pups of T lymphocytes are generally immature newborn rats if subjected to a large number of allogen antigen stimulation, allograft tolerance of the same generation Mizoguchi et al had to exclude ascites type of tumor cells Activity as an index to establish a method for quantitative determination of immune intensity of H-2K / D antigen-specific T cell transplantation.With this method, the author carried out experiments and found that neonatal rats and young rats have a good amount of alloantigens T cell transplantation immune response.Experimental BALB / c neonatal rats and young mice intraperitoneal injection (CBA × BALB / c) F_1 or (C3H ×
