The Effects Of Estradiol And Growth Hormone On Liver And Plasma Protein Of The Hypophysectomized Water Snake, Terry Chong Der

Master's Theses

The effects of estradiol and ovine growth hormone (GH) on liver and plasma protein of hypophysectomized Nat rix fasciata (southern banded water snake) were investigated. Liver and plasma protein concentrations were determined colorimetrically end expressed a mg/gm wet weight tissue.

Significant increases in liver protein levels occurred 48 and 7 hours after a single injection of estradiol in hypophysectomized animals. A single injection of GH had a like effect . Estradiol had a greater effect on liver protein levels than did GH. When estradiol and GH were administered together to hypophysectomized animals there was no apparent additive effect of the …

Comparative Age And Growth Of Two Darters, Percina Peltata (Stauffer) And Percina Notogramma (Raney And Hubbs), In Virginia, Garnett William Link

Master's Theses

Two closely related species or darters, Percina peltata and Percina notogramma, occur sympatrically in Virginia. An analysis or the number of scale annuli and standard length measurements on 447 peltata and 195 notogrannna revealed four year classes in both species, with very few individuals surviving to III-year class. Both species had approximately 1:1 sex ratios after the first year, in which males were predominant. The growth of both species was approximately the same after the first year; however peltata, the larger species, apparently gains an advantage during the first year which it never loses. The sexes did not …
