Immunomodulatory effect of IM-133.

The immunomodulatory effect of IM-133, a polyherbal formulation, has been investigated. Treatment with IM-133 enhanced the delayed type hypersensitivity (DTH) response in mice. IM-133 enhanced the in vitro response of splenocytes to mitogenic challenge. The in vivo treatment also stimulated the ex vivo lymphocyte proliferation, while the humoral response to sheep RBCs (SRBCs) was unaffected. The preferential stimulation of the components of cell mediated immunity (CMI) indicate that treatment with IM-133 affords non-specific immune stimulation.
