Abstract:

In order to investigate the expression of p-p38 in central nervous system in rats anesthetized with the Combined Anaesthetic for Miniature Pigs (XFM),30 rats were divided randomly into two groups:control group and XFM group.XFM group consisted of four subgroups:M1 subgroup (rats received XFM intraperitoneally and then waiting the disappearance of right reflection);M2 subgroup (rats received XFM intraperitoneally and then waiting for 1 h after the disappearance of right reflection);M3 subgroup (rats received XFM intraperitoneally and then waiting the recovery of right reflection) and M4 subgroup (rats received XFM intraperitoneally and then waiting for 1 h after the recovery of right reflection).The brain tissues were taken when reaching each time point.With the method of RT-PCR,expression of p38 mRNA were detected,and the expression of p-p38 in central nervous system was detected with Western blot.The results showed that,compared with the control group,the transcription of p38 mRNA on cerebellum and thalamus in experiment groups were significant lower than that in control group (P<0.05),and p38 mRNA increased at group M3 and group M4,but significantly lower than control group (P<0.05).In group M1 and group M2,the expression of p-p38 in cerebellum and thalamus were significantly lower than that in the control group (P<0.05),but the expression of p-p38 in cerebellum,hippocampus,brainstem increased significantly after administration of XFM (P<0.05) in group M1,group M2,and group M3,compared with the control group,and in group M4,the expression of p-p38 decreased,were no difference with the control group (P>0.05).These results indicated that the decrease of the expression of p-p38 in cerebellum and thalamus were induced by XFM,and these changes of p38 mRNA and p-p38 maybe one of the anaesthetic mechanisms of XFM.
