Kurze Mitteilungen

Summary

The detection of two myotropic substances in the eyestalk and the brain of the crayfishAstacus astacus and the shrimpCrangon crangon was described2. Both substances have an action on the isolated ileum of the guinea pig. The substance extracted from the eyestalk has a positive myotropic one, the substance extracted from the brain an inhibiting one.

Further a method is given for the separation and purification of the positive myotropic substance of the eyestalk by paper-chromatography.
