Abstract:
The purpose of this investigation is to evaluate the excitability of the sympathetic nerves in burned rats. Pre ganglionic discharges from the cervical and the epinephronic sympathetic nerves and post-ganglionic discharges from the renal sympathetic nerve fibers were recorded in rats anaesthized with urethane. After burning, the discharges of the sympathetic nerves of the rats at first showed continuous high frequency soon followed by a decline. After that, the sympathetic efferent electrical activity became very active again, displaying a high amplitude and high frequency.These results suggest that the sympathetic nerves system exhibits periodic excitatory changes in burned rats with a excitation-inhibition-excitation cycle.
