Issue Date
The effect of Korean Ginseng saponins (total saponin, PD saponin and PT saponin) on the serotonin type 3 receptor, which is known to be involved in nausea and vomiting following anticancer chemotherapy or the general anesthesia, was investigated. after in vitro transcribed recombinant serotonin type 3 receptor in the Xenopus laevis oocyte, classic two electrodes voltage clamp technique was used. All of ginseng saponins inhibited the response of the agonist, serotonin, on the serotonin type 3 receptor in a dose-dependent manner. PT saponin showed to have the inhibitory effect more than 2 times as potent as PD saponin. Total saponin shifted the serotonin dose response plot to the right (EC50/, 0.70±0.17 μM into 3.57±1.42 μM, and Hill coefficient, 2.14±0.60 into 1.52±1.00). Ginseng saponin did not change the reversal potential (∼0 mV) of serotonin type 3 receptor. These results suggest that Korean ginseng saponin may have the inhibitory effect on serotonin type 3 receptor.
