Abstract

1. Tryptamine is detectable in the acetone extract of glochidia by paper chromatography. This serves as a new evidence for the suggestion that this agent functions as a local hormone in these larvae. 2. From among the amino acids tyrosine, valine, tryptophan, leucine and phenylalanine were identified in the extract of glochidia by paper chromatography. 3. It was established by biological testing that the activity of some stimulatory factors in the extract of the glochidium increases on the effect of heat. The factor producing tonic contraction is heat-sensitive and its activity decreases on heat-treatment. 4. It is assumed that in the different states of ontogeny different biologically active amines are functioning as transmitters in the case of Anodonta species.
