Progressive decline of 3 H‐melatonin concentrations was found in the serum, lung, skeletal muscle, liver, kidney, salivary glduring 60 min following the administration. On the contrary, there was a progressive accumulation of radioactive substance other than 3 H‐melatonin in the salivary glbut not in other tissues mentioned. The radioactivity was also progressively preferentially localized in the nuclear fraction of the glcells. These results suggest a possible direct action of melatonin derivative in rat salivary gland.
