Research Abstract

Ulcerative colitis (UC) is supposed to have the immunological abnormalities and is treated mainly with salicyl-azosulfapyridine (SASP) and corricosteroid hormone (CS). We investigated the effect of Saireito (Chinese traditional medicine) on improving the immunological deficiency of the chemiluminescent response (CL) and cultured T lymphocyte function derived from UC patient.
One third patient with active UC stage were improved by Saireito therapy combined with CS or SASP. The activity of CL was increased in UC group compared with healthy control group. The CL activities were decreased after p. o. administration of Saireito.
The cultured T cell line derived from active UC patients were expressed CD4 positive marker and more responded CD3 antibody compared with control group. Saireitou was efficient to suppress the proliferative response in vitro. The production of TNF in established T cell line from UC patient was higher than the cell line from normal mucosa. The production of TNF was also suppressed by Saireito solution similar to corticosteroid effect.
Saireito suppressed the CL activities of neutrophils after p. o. administration. The study on T cell lymmphocyte function suggested the possibility that Saireito has some influence on immune function. On the basis of these results, we suggest that Saireito might be able to use treatment of UC not only for reducing the dose of CS or SASP but improving the immune deficiency of UC.
