The effects of starvation on the sodium, potassium, water and free amino acid content of parietal muscle from Agonus cataphractus.

1. The levels of the individual free amino acids, K, Na and water present in parietal muscle were measured in fish starved for periods of 3-115 days. 2. The Na and water content progressively increased relative to dry weight of tissue during the starvation period whereas an initial increase in the K content up to 67 days was followed by a decrease to near the normal fed level by 115 days. The ammonia content remained essentially stable over the same period. 3. The essential free amino acid content tended to follow the muscle sodium pattern while the non-essential amino acids and taurine gave results somewhat similar to those of potassium. 4. The net result of these changes is that the Na, K and total free amino acid concentration is maintained within fairly narrow limits relative to the tissue water content during 11-67 days of the starvation period under the experimental conditions used.

The effect of oxygen on the enzymes concerned in the metabolism of 5-hydroxytryptamine by rat brain and liver preparations.

1. The effect of oxygen concentration at 1 atm on rat enzyme systems concerned in the synthesis and degradation of 5-hydroxytryptamine was studied in vitro. 2. Oxygen activated tryptophan hydroxylase and the deamination of both 5-hydroxytryptamine and tyramine by monoamine oxidase. 3. Oxygen did not affect the activities of 5-hydroxytryptophan decarboxylase or peroxidase.
