Effect of Panax ginseng saponins and Eleutherococcus senticosus on survival of cultured mammalian cells after ionizing radiation.


Panax ginseng saponin and Eleutherococcus senticosus extract were applied to cells in culture in order to assess the effect of these substances on resistance to gamma-irradiation. Eleutherococcus was slightly radio protective. However, ginseng saponin at a dose of 10 microgram/ml was significantly radioprotective (Do = 2.25 Gy) compared to control (Do = 1.80 Gy) when it was present prior to gamma-irradiation. It enhanced radiation response if it was also present for 4-6 hours after gamma-irradiation (Do = 1.10 Gy). Ginseng-treated cells made 30% less RNA and 14% more protein during a 1 hour pulse of labeled intermediates. The cells were morphologically altered. It is concluded that ginseng saponin can increase radiation resistance. The effect is indirect, due to alterations in cell physiology rather than DNA repair processes.
