RELATIONSHIP OF THE SPREAD OF INDIA INK TO THE HAIR CYCLE IN RABBIT SKIN

[摘要] The spread of intra-cutan. injd. India ink as measured at the surface in the skin of rabbits is less in anagen than in telogen. Since the corium in anagen is much thicker than in telogen, this difference in spread at the surface must simply represent a difference consequent upon the injn. of similar quantities of ink into different volumes of tissue. Also, the patterns of spread in anagen and telogen are found to be distinctively different. It cannot be concluded that the spread of India ink is less in anagen than in telogen. However, for comparable results in expts. dealing with the spreading phenomenon, the stage of the life cycle must be definitely considered.
