Effects of Wen-Pi-Tang and its crude drug extracts on proliferation of cultured mouse mesangial cells

The efficacy of Wen-Pi-Tang and each of its crude drug extracts on the proliferation of mouse mesangial cells was determined in terms of [³H]thymidine uptake. When Wen-Pi-Tang was added to the medium of mesangial cell cultures, it suppressed the proliferation of mesangial cells markedly. Similar to the effects of Wen-Pi-Tang, Rhei Rhizoma, its main ingredient, exerted an inhibitory effect on mesangial cell proliferation at a relatively low concentration. Ginseng Radix and Aconiti Tuber were also an effective crude drug. As for Zingiberis Rhizoma, an inhibitory activity at relatively high concentration was noted. However, the proliferation of mesangial cells in the presence of Glycyrrhizae Radix showed no particular alteration. As is clear from the results of the present study, Rhei Rhizoma, Ginseng Radix, Aconiti Tuber and Zingiberis Rhizoma alone each exert an inhibitory effect. The inhibition of mesangial cell proliferation by Wen-Pi-Tang can thus be explained by the action of these crude drugs.     

Ginseng and ginsenoside Rg3, a newly identified active ingredient of ginseng, modulate Ca2+ channel currents in rat sensory neurons

There is increasing evidence that ginseng influences pain modulation. In spite of extensive behavior studies, the detailed mechanism of ginseng actions at the cellular level and the identity of the active substance have not been elucidated yet. Whole-cell patch-clamp recordings were used to examine the modulation of high-voltage-activated Ca2+ channel currents by ginseng total saponins and its various individual ginsenosides in rat dorsal root ganglion neurons. Application of ginseng total saponins suppressed Ca2+ channel currents in a dose-dependent manner. Occlusion experiments using selective blockers revealed that ginseng total saponins could modulate L-, N-, and P-type currents. The co-application of ginseng total saponins and the gamma-opioid receptor agonist, D-Ala(2), N-MePhe(4), Gly(5)-ol-enkephalin (DAMGO), produced non-additive effects in most cells tested and each effect was significantly relieved by a depolarizing prepulse. Overnight treatment of cells with pertussis toxin profoundly reduced the inhibition. Furthermore, we now report that ginsenoside Rg3, among the major fractions of ginseng saponins, is a newly identified active component for the inhibition. These results suggest that the modulation of Ca2+ channels by ginseng total saponins, in particular by ginsenoside Rg3, could be part of the pharmacological basis of ginseng-mediated antinociception.

New staining methodology: Eastern blotting for glycosides in the field of Kampo medicines

Ginsenosides separated by silica gel TLC blotted to a polyvinylidene difluoride (PVDF) membrane treated with a NaIO₄ solution followed by bovine serum albumin (BSA) resulted in a ginsenoside–BSA conjugate on a PVDF membrane. The blotted spot were stained by antiginsenoside Rb1 (GRb1) and Rg1 (GRg1) monoclonal antibodies (MAbs). The newly established immunostaining method, Eastern blotting, was applied for the determination of ginsenosides possessing protopanaxadiol and/or protopanaxatriol in the Kampo medicines. In this method, we developed a new way to separate the ginsenoside molecule into two functional parts using a simple and well-known chemical reaction. The sugar parts were oxidized by sodium periodate to give dialdehydes, which reacted with amino groups of the protein and covalently bound to the adsorbent PVDF membrane. The MAb bound to the aglycone part of the ginsenoside molecule for immunostaining. Double staining of Eastern blotting for ginsenosides using anti-GRb1 and GRg1 MAbs promoted complete identification of ginsenosides in Panax species. This method was validated for immunocytolocalization of ginsenosides in fresh ginseng root. In addition, Eastern blotting for the detection of glycyrrhizin (GC) was also investigated. GC can be clearly determined by Eastern blotting in the Glycyrrhiza species. It is also possible for GC in rat serum to be surveyed by Eastern blotting by simple pretreatment as a further application.
