Ethical Inspection about laboratory animals / 中国应用生理学杂志

Laboratory animals and animal experiments are foundations and important support conditions for life sciences, especially for medical research. The animal experiments have drawn extensive attention from the society because of the ethical issue. This paper takes Wenzhou Medical University as an example to give a brief introduction to the ethical review about laboratory animals in the university so as to further draw attention and concerns from the public about the ethical issue of laboratory animals. We successively introduce its scientific projects, nurturing environment and ethical review of laboratory animals.

Simultaneous determination of clozapine, olanzapine and mirtazapine in human plasma by LC-MS/MS / 法医学杂志

OBJECTIVE@#To develop a method for determination of clozapine, olanzapine and mirtazapine in human plasma by liquid chromatography-tandem mass spectrometry(LC-MS/MS).@*METHODS@#Clozapine, olanzapine and mirtazapine were extracted from plasma samples by using diethyl ether and separated by Agilent Zorbax SB-C18 column(2.1 mm x 150 mm, 5 microm). Electrospray ionization source was applied, positive ion mode was used to detect and multiple reaction monitoring mode was used to quantify clozapine, olanzapine and mirtazapine. Carbamazepine was the internal standard.@*RESULTS@#The detection limits of clozapine, olanzapine and mirtazapine were within 0.41-0.92 ng/mL. The calibration curve in the concentration range of 10.0-2000.0 ng/mL showed a good linear distribution (r > or = 0.992 4). The average extraction recoveries were within 65.7%-94.2%. Intra-day RSD and inter-day RSD were less than 6% (n = 5).@*CONCLUSION@#This method seems to be quite specific, sensitive and accurate, and can be used to detect clozapine, olanzapine and mirtazapine in forensic and clinical analytic toxicology.
