Summary

The distribution gradient of alkaline phosphatase was established as a result of histochemical investigation of the organ of Corti.

The character and the distribution of alkaline phosphatase in the organ of Corti changed after stimulation by high frequency sound waves. The concentration of the enzyme in the superior convolution did not differ from that in the control group. There was a decrease of the enzyme in the inferior convolution and its complete absence in the lowest portion. The medial convolution occupied an intermediate position.

Analogous changes were observed when the stimulation was accomplished by sound of low frequency.

The concentration of acid phosphatase in the organ of Corti underwent a change depending on the difference in frequency of the sound used for stimulation. However, the gradient ratio which was established in control animals remained unaltered.
