The effect of antidiuretic hormone on avian salt gland function

The effect of vasopressin (ADH) on the extrarenal secretory pattern from normal and contralateral chronically denervated salt glands in the conscious salt-loaded domestic goose was examined. ADH pretreatment reduced the total outputs and initial rates of water and cation concentrations 30-80% from both type glands. ADH also enhanced the onset time of secretion from the denervated glands and reduced the sodium concentration from both type glands. Both untreated and ADH-treated animals exhibited an increased output of water and cations from the denervated glands as compared with control glands. ADH caused no noticeable effect on this phenomenon.
