胸腺组织移植对变应性鼻炎患者外周血T淋巴细胞亚群的影响

Influence of thymus transplantation on T cell subsets of peripheral blood in patients with allergic rhinitis

对８０例变应性鼻炎患者行经培养的人胚胎胸腺组织块移植术，观察患者免疫功能的变化以及对该类病的疗效。先将胚胎胸腺组织块培养７～１０天，然后移植至患者的股前肌群。测定患者手术前后的Ｔ细胞亚群、血清抗原特异性ＩｇＥ水平。术后随访３年，总有效率占随访数的９２．４％，ＣＤ８阳性细胞增高，与术前比较，差异有显著性（Ｐ＜０．０１），血清抗原特异性ＩｇＥ水平较术前明显降低（Ｐ＜０．０１）。认为胚胎胸腺组织移植可以调节变应性鼻炎患者机体的免疫功能，使抑制性Ｔ淋巴细胞的数量有所增加，功能增强，ＩｇＥ水平降低，可作为该病的治疗方法之一。

Cultured human embryonal thymus graft was performed on 80 patients with allergic rhinitis to observe the immune function of the patients and the treatment efficiency. The thymus from the fetus of intermediate abortion was cultured for 7 to 10 days. The T cell subsets and serum antigen special IgE(sas IgE) level of the patients were determined before and after the thymus transplantation. The gross treatment efficiency is up to 92.4% among the trial patients after graft for 3 years and CD8 positive cells were increased with a significantly statistical difference (P<0.01), and sas IgE level was much lower than before thymus transplantation (P<0.01). It was concluded that the thymus transplantation might regulate the immune function of the patients with allergic rhinitis, including increases in the number and the function of Ts cells, and a decrease of IgE level. 
