## Abstract Each developing opossum embryo is surrounded by a shell membrane which completely separates embryonic and maternal tissues. During the eighth and ninth prenatal days, the embryos together with their limiting shell membranes float freely within the uterine lumen, surrounded only by the s

The purpose of the following experiments was to determine the effect of different levels of excess vitamin A in the diet on the activity of the thyroid gland as indicated by determinations of oxygen consumption in relation to body weight. ## Methods Twenty-seven female rats of the Sprague-Dawley
## Abstract The kinetics of polyphenol oxidase (PPO, EC 1.14.18.1) with respect to oxygen concentrations from 5 to 100% using chlorogenic acid (CGA) as substrate was examined. __In vitro__ mushroom PPO activity was determined by measuring the consumption of oxygen during the oxidation reaction. A d
