For centuries, ginseng has been used for the therapeutic purpose in oriental herb medicine. Several studies have been conducted in the past to evaluate the effect of ginseng on erythropoiesis. However the results were controversial. We therefore attempted in the present studies to evaluate the effect of ginseng on the erythropoietic activity. In one series of experiments, the recovery pattern of peripheral blood(red cell count, hemoglobin content, hematocrit and reticulocyte count) was studied in posthemorrhagic anemic rabbits. After animals were maintained with normal(control group) or 1 gm% ginseng (experimental group) diet for 2 weeks, hemorrhagic anemia was induced by withdrawing blood equivalent to 25% of the total blood volume and then changes in peripheral blood were followed for following 30 days. In other series of experiments, we studied effect of ginseng on erythrokinetics using $^{59}Fe$. $^{59}Fe(10{\sim}40\;{\mu}Ci/animal)$ was injected intravenously after animals were fed with normal (control group) or 1 gm% ginseng(experimental group) diet for 2 weeks. And radioactivities in the blood compartments were measured at appropriate intervals for 15 days. Front these various erythrokinetic parameters were estimated. Results are summarized as follows: 1) Reticulocyte count was higher in the experimental group than in the control group after 2 weeks of administration of experimental diet. During the posthemorrhagic period, the reticulocyte count increased in both the control and experimental groups, but the increase appeared much earlier in the experimental group. 2) The posthemorrhagic recoveries of hematocrit, hemoglobin content and red cell count appeared to be faster in the experimental group as compaired with the control group. 3) The half life$(T_{1/2})$ of $^{59}Fe$ in the plasma was significantly(P<0.05) shorter in the experimental group(82.6 min, N=8) than in the control group(121 min, N=6). Plasma iron turnover (PIT) of the experimental group (1.78 mg/dl/24 hr.) was approximately 4 times greater than that of the control group(0.45 mg/dl/24 hr.). 4) The maximum red cell utilization(RC-U) was 82.1% in the experimental group ana 74.5% in the control group. Red cell iron turnover(RIT) of the experimental group(1.62 mg/dl/24 hr.) was slightly higher than that of the control group(0.35 mg/dl/24 hr). 5) Erythron turnover was significantly(p<0.05) greater in the experimental group(1.27 mg/dl/24 hr.) than in the control group(0.24 mg/dl/24 hr.). Marrow transit time of the experimental group(2.05 days) tended to he faster than that of the control group(2.84 days). These results suggest that the gingseng improves the recovery of posthemorrhagic anemia and stimulates the erythropoiesis in rabbits.
