• Changes in ammonia (NH3+NH4+) and free amino acid levels in the erythrocytes and plasmaof carp Cyprinus carpio were examined after intraperitoneal injection of ammonium chloride dissolved in Ringer's solution at a rate of 400μmol per 100g body weight. Ammonia levels bothin the erythrocytes and plasma reached the maximum levels at 3 min after the treatment and droppe to the initial levels by 120 min. The pealdevels in the erythrocytes and plasma were 5.7 times and 13.2 times higher than the respective initial values. Percentages of ammonia contentin the erythrocytes were always more than 37% of the whole blood, which indicates that not only plasma but also erythrocytes play a certain role in the inter-organ transport of ammonia. Although most of the free amino acids including glutamic acid and glutamine did not show any consistent changes, the total amounts of branched-chain amino acids both in the erythrocytes and plasma changed slightly but significantly in a reverse manner to the ammonia levels.
