Abstract: AIM: To investigate the dynamic changes of ATPases and NOS activities and NO production at different anesthesia phases using thiopental and propofol anesthesia.METHODS: Thiopental of 30 mg°kg-1 or propofol of 100 mg°kg-1 was administered respectively at different anesthetic phases (induction, anesthesia, restoration, and awake), the activities of NOS and ATPase and NO production in cortex and brain stem were measured.Saline 10 ml°kg-1 was injected as the control group.RESULTS: Ca2+-ATPase and Na+, K+-ATPase activities in the cortex and brain stem were significantly decreased after administration of thiopental and propofol, especially at induction, anesthesia, or even restoration phase of thiopental group (P<0.05, P<0.01) and at anesthesia phase of propofol group (P<0.05).NOS activities and NO production decreased from induction to restoration phase with thiopental and propofol anesthesia (P<0.01).The parameters were returned near to the normal at awaken phase.CONCLUSION: Activities of ATPases and NOS and the production of NO may mediate the anesthesia effects of thiopental and propofol in the rat cortex and brain stem.
