机体抗御麻风杆菌的能力主要依赖T淋巴细胞参与的细胞免疫作用,而麻风病患者的免疫缺陷主要表现为T淋巴细胞量和质上的缺陷.因此,已有人在动物实验麻风感染和人麻风病患者身上作了胸腺移植的尝试,但胸腺中的提取物——胸腺素,在麻风临床上的应用国外未见报道.我们用从猪胸腺中提取的猪胸腺素第五组分(简称ThF_5)治疗6例麻风病患者,取得一定效果. The ability of the body to resist Leprosy depends mainly on the cellular immunity involved in T lymphocytes, while the immunodeficiency in patients with leprosy is mainly manifested as T lymphocyte volume and quality defects.Therefore, it has been in animal experiments leprosy and human leprosy Thymus transplantation in patients with the attempt, but the thymus extract - thymosin in the clinical application of leprosy has not been reported abroad.We extracted porcine thymus pig thymosin fifth component (referred to as ThF_5) Treatment of 6 cases of leprosy patients, and achieved some results.
