Objective: According to the record of mutual-detoxication and mutual restraint in ancient Chinese materia medica, to research the influence to the toxicity of Aconiti Carmichaeli Radix added the traditional Chinese medicine (TCM) which is mutual-detoxication and mutual restraint to it., Method: ICR mouse, 0.4 microL x g(-1), to pour the fluid into stomach, paired comparison of acute toxicity of Aconiti Carmichaeli Radix seperately added different ratio of Sileris Radix, Astragali Radix and Polygalae Radix, and ad-measure the dose for LD50. SD rats, administration by injection through duodenum, 20 microL x g(-1), paired comparison of heart toxicity of Aconiti Carmichaeli Radix seperately added different ratio of Sileris Radix, Astragali Radix and Polygalae Radix, and admeasure the dose for TD50., Result: LD50, and heart toxicity of TD50 were increased after Aconiti Carmichaeli Radix added separately, its toxicity attenuation is related to the ratio., Conclusion: Mutual-detoxication and mutual restraint are the summary drawed when China ancient people is in the process of using toxic TCM and it is scientific.

Objective: Through the paired comparison on the toxicity effect of Aconiti Lateralis Radix Praeparata of different compatibility proportion of Aconiti Lateralis Radix Praeparata and Glycyrrhizae Radix et Rhizoma, to observe the detoxication effect of Glycyrrhizae Radix et Rhizoma to Aconiti Lateralis Radix Praeparata., Method: Paired comparison on the mouse acute toxicity of Aconiti Lateralis Radix Praeparata and Aconiti Lateralis Radix Praeparata with different compatibility proportion of Glycyrrhizae Radix et Rhizoma, to assay the LD50. Paired comparison on the rat heart toxicity of Aconiti Lateralis Radix Praeparata and Aconiti Lateralis Radix Praeparata with different compatibility proportion of Glycyrrhizae Radix et Rhizoma, to assay the TD50. We dilute medicated serum of Aconiti Lateralis Radix Praeparata, Aconiti Lateralis Radix Praeparata plus Glycyrrhizae Radix et Rhizoma (3:1), Aconiti Lateralis Radix Praeparata plus Glycyrrhizae Radix et Rhizoma (1: 1) into 5%, 10%, 20% solution with serum free DMEM, to survey the effect of different concentration of medicated serum to the pulsing rhythm of myocardial cell of original generation newborn rat, cell surviva rate and content of LDH in myocardial cells., Result: LD50 and TD50 of Aconiti Lateralis Radix Praeparata can be increased after adding Glycyrrhizae Radix et Rhizoma Compared to the blank serum, medicated serum with Aconiti Lateralis Radix Praeparata can obviously increased the pulse rhythm of myocardial cell and the content of LDH (P < 0.05). The medicated serum with Aconiti Lateralis Radix Praeparata added different proportion of Glycyrrhizae Radix et Rhizoma can reduce the acceleration of myocardial cell's rhythm, which is induced by Aconiti Lateralis Radix Praeparata, and can reduce the content of LDH. With the increased ratio of Glycyrrhizae Radix et Rhizoma, the effect is stronger. But for the serum with different concerntration of Aconiti Lateralis Radix Praeparata or Aconiti Lateralis Radix Praeparata added Glycyrrhizae Radix et Rhizoma, there is no obvious effect to the cell survival., Conclusion: Glycyrrhizae Radix et Rhizoma has the detoxication effect through increasing the ultimatetotaldosage of Aconiti Lateralis Radix Praeparata. The detoxication effect of Glycyrrhizae Radix et Rhizoma to Aconiti Lateralis Radix Praeparata is through restraining the increased rhythm of myocardial cell and protecting the myocardial cell.

Objective: To conduct an experimental study on in vitro transdermal absorption of prepared Shangshi Zhitong cataplasm., Method: Franz diffusing cells and mice were adopted for the percutaneous penetration study. The accumulative percutaneous permeation of total alkaloids, strychnine and atropine in certain time was determined by acid dye colorimetry and HPLC., Result: The accumulative permeation of alkaloids (Q) increased with time (t), with a linear relation between them., Conclusion: The in vitro percutaneous penetration of Shangshi Zhitong cataplasm complies with the zero-order kinetics.
