临床研究共收治慢性溃疡性结肠炎 １５１例，随机分成隔药灸 Ⅰ组（６５例）、隔药灸Ⅱ组（５６例）和对照组（３０例），其中隔药灸 Ⅰ组，近期痊愈率达 ５３．８％，总有效率为 ９２．３％；隔药灸 Ⅱ组，近期痊愈５０．０％，总有效率为８９．３％；对照组，近期痊愈率３０．０％，总有效率为６６．７％。其作用机理可能是通过抑制和／或消除肠上皮细胞ＨＬＡ－ＤＲ抗原的表达，增加（强）Ｔ_８

细胞数与功能，调整Ｔ淋巴细胞亚群间的比例关系而使结肠粘膜病变得以有效地纠正。151 patients with ulcerative colitis were divided randomly into herbal cake-separated moxibustion group Ⅰ (65 cases)

herbal cake-separated moxibustion group Ⅱ (56 cases)and drug group (30 cases)as a control. A good clinical result was obtained. The short-term curative rate was 53. 8 per cent in herbal cake-separated moxibustion group Ⅰ

50. 0 per cent in herbal cake-separated moxibustion group Ⅱ and 30. 0 per cent in drug group. The effective mechanism of treatment may be relevant to depressing or eliminating the antigenic expression of HLA-DR in colonic epithelial cell
