The relationship between environmental lighting and hydroxyindole-o-methyltransferase activity in the pineal gland of steelhead trout (Salmo gairdneri)

Creator:: Smith, John Robert
Abstract:: Pineal hydroxyindole-0-methyltransferase (HIOMT) activity was monitored over a 24 h period under three different photoperiods, 16L:8D, 8L: 16D, and 12 L:12D. It was observed that in all three groups of fish HIOMT activity was high' during the dark portion of the photoperiod in comparison to activity during the light portion....

The utilization of nonliving algal products by larval oysters

Creator:: DeBoer, James Arthur
Abstract:: Although studies have shown that some marine invertebrates can obtain a portion of their nutrition from dissolved and nonliving particulate organic matter, the relative importance of such foods in their diet has not been established. The success of oyster hatcheries could be significantly improved if the diet of living algal...

Histologic effects of chronic selenium deficiency in selected tissues of laboratory rats

Creator:: Sprinker, Lucas Harry
Abstract:: The selenium-responsive syndromes and the discovery of Factor 3-selenium focused attention on selenium in metabolism. Two hypotheses have been advanced to explain the metabolic effect of selenium: 1) substitution or sparing of alpha tocopherol, and 2) a primary role in metabolism. The first hypothesis is supported by Scott and Desai,...
