Methods Seven probe drugs were incubated with or without methyl protodioscin respectively in human microsomes. The specific substrates used in this study were caffeine (CYP1A2), dextromethorphan (CYP2D6), tolbutamide (CYP2C9),-mephenytoin (CYP2C19), chlorzoxazone (CYP2E1), coumarin (CYP2A6) and midazolam (CYP3A4). The concentrations of the substrate metabolites (paraxanthine, dextrorphan, 4-hydroxytolbutamide, 4-hydroxymephenytoin, 6-hydroxychlor-zoxazone, 7-hydroxycoumarin and 1-hydroxymidazolam) were determined by HPLC and LC-MS/MS.

The aim of this research is to find out the experimental parameters that affecting the results when analyzing bacteria by MALDI TOF MS, and to set up a general sample preparation protocol for establishing mass database of Bacillus anthracis and Yersinia pestis. It will play an important role in rapid identification of bacteria, and tracing its origin in the scenario of bioterrorism and outbreak of infectious disease for microbial forensic analysis. Methods:As for the universalness of sample preparation protocol for bacterial analysis by MALDI TOF MS, bacteria being investigated included: gram-positive bacteria including B.

And then adding NAA at low concentration in MS was used to give rise to roots. We also found that lower level of hormone could control effectively browninng and vitrifaction during the culture and G1 n (6mg/L) and AgNOj (2mg/L) supplemented in shoot induction media could improve the shoot information rates apparently (about90%).The whole period of plant regeneration from leaflets of peanut could be divided as five steps: germination - shoot induction -shoot elongation-rooting- tranplant.
