Abstract
The sacral nerves or the hypogastric nerve were divided in 23 adult male dogs, and QO2, QCO2 and the activities of succinic dehydrogenase (SDH) and latic de-hydrogenase (LDH) of the prostatic tissue were measured on the 7th and 21st postoperative days. The results were summarized as follows:
1) QO2, QCO2 and R. Q. usually decreased after the interruption of prostatic innervation.
2) Both SDH and LDH activities usually increased, while the SDH/LDH ratio was always reduced because the increase in LDH activity was larger than that of SDH.
3) These changes were also observed after division of the hypogastric as well as the sacral nerves.
4) The changes persisted for a considerably long period.
