A novel, self-designed cold/hot plate differentiating instrument, with methodological study, was used to investigate the intervention of Strobal and Rhubarb on the temperature tropism of mice. Compared with the ICR and BALB/c mice, it was found that KM mice on the cold/hot plate were more sensitive to the change of temperature, within the tolerant temperature range of 15-40 ℃ . The temperature tropism behavior of mice is influenced by treatment with Rhubarb and Strobal, as is the activity of ATPase in liver tissue. These trends are consistent with the definition of the Cold/Hot nature of Chinese medicines based on traditional Chinese medicinal theory. This study showed that the differences of the Cold/Hot nature of traditional Chinese medicines. might be objectively represented by the temperature tropism of animal by means of cold/hot differentiating assay.展开更多

Since few works have been contributed to understanding the TCM theory, the mechanism of actions of drugs with cold/hot properties remains unclear. In the present study, six kinds of typical herbs with cold or hot properties were orally administered into mice, and serum and liver samples were analyzed using an untargeted nuclear magnetic resonance(NMR) based metabolomics approach coupled with similarity analysis. This approach was performed to identify and quantify changes in metabolic pathways to elucidate drug actions on the treated mice. Our results showed that those drugs with same property exerted similar effects on the metabolic alterations in mouse serum and liver samples, while drugs with different property showed different effects. The effects of herbal medicines with cold/hot properties were exerted by regulating the pathways linked to glycometabolism, lipid metabolism, amino acids metabolism and other metabolic pathways. The results elucidated the differences and similarities of drugs with cold/hot properties, providing useful information on the explanation of medicinal properties of these TCMs.展开更多

In this study, the divergency between the "Cold" and the "Hot" natures was investigated through examining the temperature tropism of mice affected by Coptis chinensis Franch and its processed materials by using a cold/hot plate differentiating technology. After exposure to C. chinensis Franch, the macroscopic behavioral index of the remaining rate (RR) on a warm pad (40℃ ) significantly increased (P<0.05), suggesting the enhancement of Hot tropism. The internal indexes of adenosine triphosphatase (ATPase) activity and oxygen consuming volume decreased significantly (P<0.05), suggesting the decapability of energy metabolism. This external behavior of Hot tropism might reflect the internal Cold nature of C. chinensis Franch. However, the processed materials of C. chinensis Franch exhibited a different Cold nature in temperature tropism compared with crude C. chinensis Franch (CC): the Cold nature of bile-processed C. chinensis Franch (BC) enhanced while the ginger-processed C. chinensis Franch (GC) changed inversely. The changing sequence was consistent with the theoretical prognostication. It is indicated that the external Cold & Hot natures of Chinese medicine may possibly reflect in an ethological way for the changes of animal’s temperature tropism which might be internally regulated by the body’s energy metabolism.展开更多

Meanwhile,the total anti-oxidant capability（T-AOC） activity were detected.Results：After administration of MHD, the mice showed increased oxygen consumption（P0.01）.Compared with MHD group,the remaining rate of MXSGD mice on the hot pad was found to be significantly increased with the cold-hot pad differentiating assay （P0.05）.There was no significant difference（P0.05） among the remaining rates of MXSGD,MXSGD with high dose Gypsum Fibrosum（MXHGF） group,and MXSGD with low dose Gypsum Fibrosum（MXLGF） group mice.Compared with the MHD group,T-AOC activity of the mice in the Consensus Compositons group was significantly decreased（P=0.0494）.Compared with the MXSGD group,T-AOC activity of Gypsum Fibrosum （GF） group was increased significantly（P=0.0013）.Conclusions：The differences in cold and hot nature could be represented objectively between MHD with a hot nature and MXSGD with a cold nature.The reason may be the Gypsum Fibrosum which decreased the efficacy of the consensus compositions.However,increasing or decreasing the dose of Gypsum Fibrosum will not change the cold and hot nature of MXSGD.展开更多
