Ultrastructural demonstration of nerve endings containing a substance related to growth hormone-releasing factor in the guinea-pig paraventricular nucleus.

abstract：:Effects of prolactin on the secretion of milk proteins have been investigated by incubating mammary tissue fragments from lactating rabbits. Within 15 min of adding the hormone to the incubation medium, cell morphology is modified: the relative volume occupied by the Golgi region is greatly increased. When prolactin i...
