Cell dynamics after intraperitoneal (i.p.) and oral administration of a traditional herbal medicine, ren-shen-yang-rong-tang (Japanese name: ninjin-youei-to, NYT), were investigated. When NYT was injected i.p. into C3H/He mice, numbers of spleen and peritoneal cells significantly increased in a dose-dependent manner and showed high levels from 4 to 21 days. Two peaks in the total cell number were observed on days 7 and 14 in the peritoneal cavities and spleen of C3H/He mice administered NYT. A marked accumulation of PMN cells in the peritoneal cavity and spleen was detected at 7 days after injection. The numbers of macrophages and lymphocytes also increased by i.p. administration of NYT. The thymus cell number decreased transiently between 4 and 7 days and thereafter returned to the control level. No significant change in the cell number of lymph nodes was observed. Such cellular accumulation was also detected in C3H/HeJ mice, a nonresponder strain to bacterial endotoxin, and athymic nude mice. The activity of colony-forming units in the spleen (CFU-S) of C3H/He as well as C3H/HeJ mice was markedly augmented by i.p. administration of NYT. NYT induced significant CSF production as detectable by its activity in the sera. In addition, oral administration of NYT for 10 days induced a significant increment of peripheral leukocytes and spleen cells and enhanced CFU-S activity of bone marrow cells as induced by i.p. administration, indicating that NYT acts on hematopoietic stem cells capable of differentiating to lymphocytes, macrophages and PMN cells into the periphery.
