Padma 28

Abstract Extract of traditional Tibetan herbal remedy Padma 28 revealed suppressive effects on neopterin production and tryptophan degradation in mitogen-stimulated peripheral blood mononuclear cells (PBMC). One of the questions was to asses the robustness of the Tibetan way of formulating herbal multicomponent medicines. Can small changes affect the effectiveness of the formula? In this study, effect of a derivative multicomponent mixture was investigated in stimulated and unstimulated human PBMC in vitro. Neopterin production and tryptophan degradation were measured in supernatants of PBMC in the presence or absence of mitogens phytohacmagglutinin and concanavalin A. Stimulation of PBMC induced neopterin formation and tryptophan degradation, and the herbal multicomponent mixture inhibited both immunobiochemical effects in a dose-dependent way. Higher concentrations were more effective and were able to completely block the pathways induccd upon mitogenic stimulation. When comparing the results obtained with those observed earlier using Padma 28, there was no obvious difference between the two different preparations. Data allow to conclude that Padma 28 and its modified version is equally able to suppress immunobiological effects in stimulated PBMC.
