Influence of peripheral cholinergic blocking drugs on survival time in x-ray irradiated mice.

the alternate use of sunlight and an improvised electric plate oven. Because any difference in the environment will be reflected in the food and therefore the nutrition, this fact will continue to remain as a possible explanation for the differences between the lots fromii Hawaii and the Palau Islands. At the height of reproductive activity, the albumen gland of the female conduit in these hers-Aaphroditic animals may become so large that it actually exceeds the size of the liver or digestive gland. Because of the proteinaceous nature of albumen, the hypertrophy of this gland is almost certain to produce changes in the amiino acid ratios. A comparison of the values for Lot D with those of Dunn (4) indicates that arginine is nearly 21/3 and lysine over 11/3 times the amounts in whole egg. All other values, although appreciable and significant, fall below the values for whole egg. Similar analysis of cottonseed meal (5) shows that its value as a poultry and livestock feed is limited, as is almost universally the case with many other vegetable products, because of the deficiency of the very essential amino acid, lysine. The immediate inference is that this deficiency could be overcome through the addition of snail meal. Tests designed to determine both the effectiveness of this combination and the growth adequacy factors of snail meal alone are currently being set up through the use of controlled chick feeding experiments at the University of Arizona. It is expected that the results of these tests, along with additional amino acid assays, will be announced at an early date.
