Immunohistochemical detection of serotonin in the skin of frogs (Rana ridibunda) kept at different temperatures

Abstract

This study investigates the location of serotonin in the skin of frogs (Rana ridibunda) kept at two different temperatures (24–25◦C and 4◦C) and discusses its possible function from a different point of view. In the frogs kept at 24–25◦C, some cells of several small and large mucus glands and lumen material of some large mucus glands are serotonin… (More)
