[Acetylcholinesterase activity in spiral ganglion cells in rats]

Acetylcholinesterase has been demonstrated in the spiral ganglion cells by the method of Karnovsky and Roots. After incubation for 24 h the content of AchE was measured with the help of a three-stage scale. 22% of the cells showed strong, 50% medium and 28% weak AchE activity. Within the spiral ganglion perikarya, the enzyme was equally distributed.
