Abstract:
OBJECTIVETo observe the effect of Guizhi Decoction (GZD) on immunological indexes in intestinal mucosal immune system of mice with Bi syndrome (collagen induced immune arthritis).
METHODSEighty male DBA mice were randomly divided into 4 groups, the normal group, the model group and the high and low dosage GZD groups. Model of Bi syndrome was induced by collagen type II. CD4+, CD8+ T-lymphocytes and SIgA in mice' small intestine and PP node were labeled by immunohistochemical staining and their number was calculated using imaging analyzer.
RESULTSCompared with the normal group, in the model group, after immunization with collagen type II, numbers of CD4+ and CD8+ T-lymphocytes and SIgA in mice' intestinal mucosal immune system reduced significantly (P < 0.05 or P < 0.01). After treatment with GZD of both high and low dosage, CD4+ T-lymphocytes and SIgA increased significantly, but significant difference only showed in comparison between the high dosage GZD group and the model group (P < 0.05 or P < 0.01).
CONCLUSIONGZD could enhance the immune function in intestinal mucosa in mice with Bi syndrome, thus it might induce immune tolerance and immune inhibition.
