 Abstract    The effects of a number of phenylethylamines on the metabolism of brain biogenic amines have been studied with the aim of differentiating neurochemi-cally between those drugs having a stimulant profile from those which are hallucinogenic 1_5. The pre­ sent study was undertaken to see if some of these drugs had a similar effect on the metabolism of serotonin in the oesophageal ganglia of the snail so that an assessment could be made of the possible usefulness of this in vitro preparation in the initial

 Title    Biochemical and Electronmicroscopic Investigations on Helix pomatia Collagen A-8036 Graz, Austria  
 Abstract    The skin o f Helix pomatia was investigated by biochemical methods and electronmicroscope. Biochemical investigations showed that Helix pomatia collagen represents a methionine-lacking collagen resistant to CNBr-cleavage. Electron microscopic studies showed a cross striation pattern of 5 3 -5 7 nm.

 Title    Fluorescence Monitoring of Membrane Potentials: the Spatio-Temporal Resolution in Isolated Neurons of Helix pomatia  
 Abstract    Using amino-styryl-pyridinium dyes as fluorescent probes we have studied the membrane potential in spheroidal neurons isolated from the circumaesophageal ganglia of the snail Helix pomatia. A spatial resolution of 10 ^im is attained at a time resolution of 2.5 ms with a typical signal-to-noise ratio of 10/100 mV as referred to an average sensitivity of the probes of 3%/ 100 mV and to a quantum yield of the detector of 0.13. The linear response of fluorescence, the effect of staining, the variation of sampled area and of illumination are characterized.
