Abstract

The amount of melanin in the stria vascularis was computed, using three type of hamsters was found to be different in the color of coat and iris. The amount of melanin contained in the intermediate cells correlates with the degree of pigmentation in the animal's coat and eyes. Wild type of the hamster were found to dendritic melanocytes beside the basal cell. But the dendritic melanocytes were not found in TPB or MP. Thus, the melanocyte of the inner ear is controlled by genotype P, (pink eye dilution). In the heterochromia of iris, the amount of melanin in stria vascularis tends to increase, in proportion to the amount of the melanin in iris.
