Abstract

The preventive effect of pre-ganglionic decentralization (Sympathetic trunk resectioN) or postganglionic excision (ganglionectomy) of the superior cervical ganglia on thermal injury induced brain edema or the development of heat stroke was assessed in rats. Brain edema was induced by cold or heat injury to the cortex in 24 rats. The results showed that decentralization, but not excision, of the superior cervical ganglia greatly inhibited the formation of brain edema which was subsequently induced. When heat stroke was induced by exposing 24 rats to an ambient temperature of 41 degree C, the latency for the onset of the heat stroke and the survival time after the heat stroke were greatly prolonged by the former surgical procedure, but shortened by the later one. The present study demonstrates the potential benefit to brain edema and heat stroke of the pretreatment with decentralization of the superior cervical ganglia.
