Summary
In the normal Wistar rat, the plasma α-MSH level was raised by hypertonic saline injection (as compared with control rats injected with isotonic saline). No such rise in α-MSH followed hypertonic saline administration in the Brattleboro (hereditary diabetes insipidus) animal (compared to isotonic saline injected controls). It is suggested that, in the rat, endogenous antidiuretic hormone is involved in the secretory response of the pars intermedia to osmotic stimuli.
