Observation on the subclasses of IgG and subsets of T cell in 120 patients with inflammatory polyps of large intestine / 第三军医大学学报

ABSTRACT

Objective　To study the corelation between patient with inflammatory polyp of large intestine and the changes of immunologic function. Methods　Polyps of large intestine were extirpated from 120 patients with fiberoptic colonoscope and the pathological changes were studies. IgG subclass and T cell subsets in the peripheral blood were determined by ELISA and IFA methods. Similar parameters were determined in 30 cases of chronic colitis as control. Results　CD8 in patients were lower than that of the control and CD4/CD8 were increased compared with those in control. Conclusion　Disorder of humoral and cellular immunity might play an important role on the pathogenesis of polyp of large intestine.
