Biochemical responses elicited in normal or prolactin-treated Xenopus laevis (Daudin) specimens by environmental changes

1. 1. Biochemical responses to environmental changes were recorded in normal or prolactin-treated Xenopus laevis specimens. 2. 2. Maintenance on moist moss elicits the urea cycle activation, while prolactin does not; hepatic ammonia concentration decreases in both cases. 3. 3. In the animals reared...

Beschreibung
Zusammenfassung:	1. 1. Biochemical responses to environmental changes were recorded in normal or prolactin-treated Xenopus laevis specimens. 2. 2. Maintenance on moist moss elicits the urea cycle activation, while prolactin does not; hepatic ammonia concentration decreases in both cases. 3. 3. In the animals reared on moist moss the activity of intestine alkaline phosphomonoesterase is enhanced, but drops significantly after prolactin treatment; this enzyme is not significantly reduced in fresh-water prolactintreated animals. 4. 4. Both rearing on moist moss and prolactin treatment elicit sodium gain in the muscle; permanence on moist moss leads to potassium loss which is abolished by prolactin.
