ABSTRACT
Objective To clarify the effective location of propofol in central nervous system (CNS) by detection of the c-jun expression after propofol-induced anesthesia in rats. Methods Wistar rats were randomly divided into 6 groups normal control (C), low-dose propofol group (50 mg/kg, P 1), middle-dose propofol group (100 mg/kg, P 2), high-dose propofol group (150 mg/kg, P 3), stimulation with tail broken group (S 1), and propofol + stimulation with tail broken group (S 2). The expressions of nucleoprotein JUN in the CNS were detected by immunohistochemisty. Results Rather weakly stained nucleoprotein JUN positive neurons were observed in the supraoptic nucleus, lateral septal nucleus, and lateral habenular nucleus in the control group. In groups P 1, P 2, and P 3, the expressions of nucleoprotein JUN were increased significantly as compared with those in the control group. The expressions were mainly located in the accumbent nucleus, lateral septal nucleus, periventricular hypothalamic nucleus, ventral lateral geniculalaten nucleus, dorsal lateral geniculate nucleus, supraoptic nucleus, suprachiasmatic nucleus, anteroventral preoptic nucleus, nucleus of the solitary tract, supramammillary nucleus, basolateral amygdaloid nucleus, paraventricular thalamic nucleus, lateral habenula nucleus, and islands of Calleja. The expressed positive neuron number was positively correlated with the doses of propofol. Conclusion Propofol anesthesia has the determined sites of action in rat CNS.
