[Radioautographic study of melanin synthesis in cells of the pigmented epithelium of the retina in adult tritons following surgical removal of the retina].
The results are given for the autoradiographic study of melanin synthesis in the pigment epithelium cells of eye retina in the adult newts by the incorporation of 3H-dioxyphenylalanine (3H-DOPA). The synthesis of melanin began 4--8 days after the operation in the peripheral parts of the eye and but it was not observed in the central region of the eye fundus even 25 days alter the operation. A suggestion is put forward to the effect of the existence of different mechanisms for the initiation of melanin synthesis in these subpopulations of pigment epithelium.
