Animals which had been exposed to water traumatization in infancy were more emotional and made more errors on a water escape maze, but not on avoidance conditioning, than did non-traumatized control animals. The results, in conjunction with previous findings, suggest that early experience effects are trauma-relevrnt and do not generalize to all stressful situations experienced in adulthood.

It has been shown for some time that it is possible to obtain images of small unstained proteins, with a resolution of approximately 5Å using dark field electron microscopy (1,2). Applying this technique, we have observed a uniformity in size and shape of the 2-dimensional images of pure specimens of fish protamines (salmon, herring (clupeine, Y-l) and rainbow trout (Salmo irideus)). On the basis of these images, a model for the 3-dimensional structure of the fish protamines has been proposed (2).The known amino acid sequences of fish protamines show stretches of positively charged arginines, separated by regions of neutral amino acids (3). The proposed model for protamine structure (2) consists of an irregular, right-handed helix with the segments of adjacent arginines forming the loops of the coil.
