The Effects of Korean Ginseng Components for the Mouse Irradiated 1 by Neutron(Besource)

When mice irradiated by neutron (Be) are fed with ginseng concentrate, ginseng powder, and adaptagen of which the major ingredient is ginseng alkaloid to neutron (Be source) irradiated mouse, the following results are obtained. 1. The 50% lethal dose (LD50) for the neutron irradiation were 4 days at 600 rad, 7 days at 500 rad, 16 days at 400 rad, 33 days at 375 rad, and 55 days at 350 rad. In thistest, the standard amollntofirradiation was set at 375 rad/8 min. 2. Some spots appeared in the tail of the neutron-irradiated mouse because of blood congestion, and some had its tip tails cut. But the group administered with adaptagen did not show any of these symptoms. 3. The neutron irradiated mouse showed darkening the color of their lung-chloasmas while none of the adaptagen group had this symptom. 4. The lung tissue of the neutron irradiated mouse showed an increase of the karyolysis and cytoplasmic vacuole. 5. When both neutron irradiation and the ginseng sllbstances were given to the mouse at the same day, the 50% lethal days were increased to 29-33 days for the group administered with ginseng extract. 67 days for the group given with the ginseng powder. and 80 days for the groilp arith the adaptagen. 6. The survival rate of those fed with adaptagen for 33 days before the neutron-irradiation was 100%, while the 50% lethal daysofthe group fed with ginsengextract were 39 days and that of the group fed with ginseng powder were 69 days. 7. The serum valued of ${\gamma}$-globulin, IgG, and albumin were returned to normal condition in the group fed with adaptagen for 33 days before the neutron-irradiation. But those of the group which were given the irradiation and the ginseng substances at the same day did not show such a recovery.
