한약재인 황금의 궤양성 실험동물에 대한 장간막 임파절 임파구의 면역글로블린 수준, T세포 집단, 사이토카인 생성의 조절작용

초록

We previously examined extracts, isolated from Scutellaria baicalensis (SB), chemical mediators, and IgE by mesenteric lymph node (MLN) lymphocytes in rats. The present study was to evaluate the effects of extracts of SB on the MLN lymphocytes function of mice given orally by 20㎎/㎏ for 2 weeks with dextran sulfate sodium (DS)-induced colitis. Results show that IgE levels in MLN lymphocytes was low, while IgA was high, in mice given SB compared to that fed water. Concentrations of inteferon-γ and interleukin (IL)-2 of T cells by concanavalin A treatment was significantly higher in the SB fed group than the normal group. Activation-induced IL-4 and IL-10 secretion was lower in SB fed mice compared control mice after DS-induced colitis. These results suggested that SB suppresses the inflammation in DS-induced colitis through the modulation of Th1/Th2 balance to down-regulate Th2 response in MLN lymphocytes.
