克隆氏病(CD)和溃疡性结肠炎(UC)统称为非特异性炎性肠病(IBD),这两种疾病在临床、病理和免疫学方面有很多相同之处。IBD 的病因尚不清楚,免疫因素在发病机制中的作用国内外均有报导,尤以血液淋巴细胞功能测定为多,但结果不尽相同,其原因可能是血液免疫试验不能直接或充分反映胃肠道病变部位的病理过程。本研究以免疫组织化学方法观察 CD 和 UC 病人的肠粘膜分 Crohn’s disease (CD) and ulcerative colitis (UC) are collectively referred to as non-specific inflammatory bowel disease (IBD), both of which have many clinical, pathological and immunological similarities. The etiology of IBD is not yet clear, the role of immune factors in the pathogenesis both at home and abroad have been reported, especially in blood lymphocyte function determination for more, but the results are not the same, the reason may be blood test can not directly or fully reflect the stomach Pathological process of intestinal lesions. In this study, immunohistochemical staining of CD and UC patients with intestinal mucosa
