The hypothalamic and neurohypophysial vasopressin content as influenced by diphenylhydantoin in dehydrated rats.
Rats dehydrated up to 8 days were treated with diphenylhydantoin given intraperitoneally in daily doses of 10 mg/100 g of the initial body weight. The single dose of diphenylhydantoin diminished the vasopressin content in the hypothalamus and neurohypophysis of normally hydrated rats. Under conditions of severe dehydration (8 days), DPH treatment resulted in a more marked decrease of vasopressin in the hypothalamo-neurohypophysial system.
