Dual direction regulatory effect of catalpol on ?-adrenergic receptor and M-cholinergic receptor / 上海第二医科大学学报

Objective To investigate whether catalpol is the active component responsible for the Yin tonic effect of Radix Rehmanniae.Methods Young NH mice were injected with triiodothyronine to produce the hyperthyroidism model,while old mice were used as the model of natural aging.The single point radioligand binding assay was carried out to determine the ?-adrenergic receptor density and M-cholinergic receptor density.The learning ability(short term memory) was determined by the Y-maze avoidance test. Results In the ?-adrenergic receptor experiment,the densities were(15.7?5.2) and(20.9?7.2) fmol/mg protein in normal control group and in T3 control group(P
