Formatted abstract
1. The osmolality and concentrations of Na, K, Cl and the hormones arginine vasotocin (AVT), prolactin, aldosterone and corticosterone were measured in plasma as functions of time in relation to oviposition, changing NaCl content of the diet, and feeding-inanition.

2. AVT was significantly increased immediately after oviposition (but not during the hour before) with a calculated average value of 38.0 ± 4.1 pg/ml at oviposition.

3. A moderate increase in concentrations of prolactin and corticosterone were observed immediately after oviposition.

4. Oviposition was not associated with detectable changes in plasma osmolality (and electrolyte concentrations) nor with the concentration of aldosterone.

5. After a sudden change from a high NaCl diet to a low NaCl diet the plasma osmolality and concentrations of NaCl, AVT and prolactin reached new stable levels in 24 hr, whereas the plasma aldosterone concentration required more than 4 days to reach a steady level.

6. After resalination plasma aldosterone was suppressed in less than 8 hr.

7. Both osmolality and concentrations of AVT and prolactin showed transient overshoots during the first 24 hr. 8. NaCl depletion resulted in a transient increase of corticosterone.
