The purpose of this research was to investigate the effect of Yonggak-san (YGS) on the immune reaction and apoptosis of leukemia cells. Administration of YGS(500 mg/kg) enhanced proliferation of splenocytes, thymocytes and mesenteric lymph node cells, and also YGS accelerated subpopulation of splenic Band T, thymic T and mesenteric lymph node-T lymphocytes, especially significantly increased CD4+-TH cells in BALB/c mice. YGS accelerated phagocytic activity and production of nitric oxide in peritoneal macrophages. YGS induced apoptosis of transplanted-L1210 cells in vivo, increased apoptotic cell death of cultured-L1210 and/or Molt4 human leukemia cells, decreased of mitochondrial transmembrane potential of both cells in vitro. These results suggest that YGS have an immune-regulatory effect and anti-cancer property.
