Corticosteroid Secretion

SUMMARY Cyclical changes in the activity of adrenocortical tissue are a wellestablished phenomenon in many amphibian species but up to now they have been studied by observing changes in cytology or enzyme activity, e.g. steroid-3β-ol dehydrogenase. The present study was designed to provide a measure of corticosteroid secretion throughout the seasons using the in-vitro approach. Concomitant histological changes are also recorded and together provide evidence that the adrenal tissue of Rana rugulosa shows maximum activity in the spring spawning season and reaches a minimum in winter.

Biochemical Analyses

Thirty-three mature male Holtzman rats were randomly placed in 3 treatment groups: Controls (C); Ethanolics (E); and Wine drinkers (W). The animals were fed synthetic diets (Lieber type) with ethanol or wine substituted isocalorically for carbohydrates in the diet of E and W groups, respectively. W received a volume of wine which provided the same gram quantity of alcohol consumed by E. The animals were sacrificed by decapitation after 6 weeks and the livers processed for quantitative triglycerides (T3), proteins, malic enzyme activity (MEA), light microscopy (LM) and electron microscopy (EM). Morphometric analysis of randomly selected LM and EM micrographs was performed to determine organellar changes in centrilobular (CV) and periportal (PV) regions of the liver. This analysis (Table 1) showed that hepatocytes from E were larger than those in C and W groups. Smooth endoplasmic reticulum decreased in E and increased in W compared to C values.
