Abstract
Summary
The effect of mammalian ACTH on in vitro secretion of skate (Raja erinacea) interrenals was investigated directly. Inter-renal weights also were compared between males and nonovulating and ovulating females. ACTH increased interrenal output of BT and UV measurable substances in both sexes. Preincubation output rates in the absence of ACTH were substantially greater than those during subsequent incubation. A strong but not perfect correlation was observed between body and interrenal weights in both sexes. F-test analysis for statistical significance of differences between means of covariance-corrected interrenal weights showed that those of males were significantly less than those of either combined or ovulating females but not different from those of nonovulating females. Ovulating females had significantly heavier interrenals than nonovulating females.
