丙泊酚对大鼠脑突触体Na+, K+-ATP酶和Ca2+-ATP酶活性的影响

Effect of propofol on Na⁺, K⁺-ATPase and Ca²⁺-ATPase activities of cerebral synaptosomes was investigated in rats. It was found that propfol 50 mg·kg^-1 ip significantly inhibited Na⁺, K⁺-ATPase activity of hippocampal and brain stem′s synaptosomes (P<0.01). Propofol 100 mg·kg^-1 ip significantly reduced Na⁺, K⁺-ATPase and Ca²⁺-ATPase activity of cerebrocortical, brain stem′s and hippocampal synaptosomes (P<0.01). It is suggested that the central inhibitory effect of propofol may be related to the inhibition of Na⁺, K⁺-ATPase and Ca²⁺-ATPase activity of cerebral synaptosomes.
