RESUMO
Aim To investigate the effect of SM-1 on seven main cytochrome P450(CYP450)in human liver microsomes.Methods Substrate or SM-1 was incubated with human liver microsomes for 30 min in vitro,and divided into control group and experimental group.The effects of SM-1 on the main phase I metabolic enzymes in human liver microsomes was detected by HPLC.Phenacetin,bupropion,paclitaxel,tolbutamide,omeprazole,dextromethorphan,testosterone were investigated as probe drugs.Results Inhibition rate of SM-1 on the classical substrate of human liver microsomal CYP was 0.05％,3.37％,0.08％,2.07％,4.20％,-0.15％and 10.84％,respectively.Conclusions SM-1 may have inhibitory effect on CYP3A4.Attention should be paid to the interaction of clinical drug induced by CYP enzyme inhibition.
RESUMO
Objective To study the teaching effects of using case discussion-analysis method in the teaching course of Nursing Research among nursing students and then put forward suggestions for improving teaching.Methods By way of case discussion-analysis,a part of teaching contents of Nursing Research were taught to the 118 nursing students in 2003 grade.The teaching effect was evaluated by observing the design ability of scientific research,the learning interest,learning attitude,etc.Results The design ability of scientific research,recognition of Nursing Research,learning attitude and learning interest,etc of the students were significantly improved.Conclusions Case discussion-analysis method could effectively excite the interest and the potential of students and then improve the ability of discovering and solving problems.
