Abstract:
Objective To establish an objective method for evaluating the intrinsic characteristics between cold and hot nature of Chinese materia medica (CMM) through the different effects of Mahuang decoction (MHD) and Maxing Shigan decoction (MSD) on animal temperature tropism. Methods The equipment with cold/hot pads was used to investigate the variety of the temperature tropism between two groups of mice treated by MHD and MSD, respectively. Meanwhile, the activities of adenosine triphosphatase (ATPase), superoxide dismutase, succinate dehydrogenase, and malondialdehyde were measured. Results After treated by MHD, the macroscopic behavioral index of remaining rate on warm pad (40 ℃) of mice decreased significantly (P < 0.05), suggesting the enhancement of cold tropism, meanwhile, the internal indices of ATPase activity and oxygen consuming volume increased significantly (P < 0.05), suggesting the enhancement of energy metabolism. On the other hand, the above-mentioned indices in MSD group changed on the inverse way. Conclusion The relative drug nature of MHD and MSD revealed in this study is consistent with the theoretical prognostication or definition. It indicates that the internal cold and hot nature of CMM could be reflected in ethological way on the changes of animal temperature tropism which might be internally regulated by body energy metabolism.
