title: Acetylcholine content of the brain and visceral organs of the teleostean fish; Heteropneustes fossilis and Clarias batrachus.
abstract: The acetylcholine content of various organs of two teleostean fish, Heteropneustes fossilis and Clarias batrachus has been estimated biologically on the eserinized frog rectus muscle. The acetylcholine content in the stomach of both the fish was 0.341 and 0.22 mug/g, respectively. Values were lower than those of other parts of the alimentary tract. The ilia contained the most acetylcholine, being 0.644 and 0.551 mug/g respectively, for the two fish. In the brain, heart, kidney and liver of both the fish, a considerable amount of acetylcholine was detected. Acetylcholine was not found in the spleen of Clarias batrachus, but it was present in the spleen of Heteropneustes fossilis.
