Abstract
The effects of Juzentaihoto (TJ-48) on cellular immunity were investigated by using delayed type hypersensitivity (DTH) reaction, mixed lymphocyte culture response (MLR) and cytotoxic T lymphocyte (CTL) response. Oral administration of TJ-48 was found to induce the augmentation of DTH and CTL responses. TJ-48 tended to enhance the MLR although it was not statistically significant. These results suggest that TJ-48 has an immunopotentiating activity on cellular immunity in addition to humoral immunity which we have reported previcusly.
