Orally administered Kampo (Japanese herbal) medicine, "Juzen-Taiho-To" modulates cytokine secretion in gut associated lymphoreticular tissues in mice.
Phytomedicine 2000; 6(6):425-30P

Abstract

The influence of the oral administration of Juzen-Taiho-To (JTT; Si-Quan-Da-Bu-Tang in Chinese), a Kampo (Japanese herbal) medicine, on the cytokine production in mice were investigated. Lymphocytes from spleen (SPN), mesenteric lymph node (MLN) and Peyer's patches (PP) from mice, which received orally administered JTT for 2 weeks, were stimulated with concanavalin A (Con A), and the resulting conditioned medium was tested for cytokine production by ELISA. Administration of JTT caused enhancement of interferon g (IFN-gamma) and interleukin-4 (IL-4) production to some extent but decreased IL-5 production from the SPN. On the other hand, notable changes in cytokine production were observed in lymphocytes from MLN and PP. Administration of JTT increased IFN-gamma production remarkably, as well as IL-5 secretion from both MLN and PP, whereas IL-2 secretion was plainly reduced. The ratio of IFN-gamma and IL-4 was shifted to Th1 dominant in MLN and PP, however changed little in SPN. The flow cytometric analysis revealed that the population of CD3+, CD4+, CD45R/B220+, and CD45RBlowCD4+ cells in each lymphocyte was not changed significantly after oral administration of JTT. These findings demonstrate that the lymphocytes from gut associated lymphoreticular tissues (GALT) are more sensitive to produce cytokines on cytokine production than those from SPN by oral administration of JTT, and that the modulation of cytokine production may be due to functional change of lymphocytes but not change in lymphocytes population.
