Publisher's Synopsis
Excerpt from Studies in the Regeneration of Blood
Hemorrhages of approximately one-third of the estimated total. Blood volume can be borne by albino rats without interfering with complete recovery. When one-half or more of the blood was removed by hemorrhage, death ensued. The criteria used in judging blood regeneration in the rat were the return of the number of erythrocytes and the percentage of hemoglobin to the values noted before the animal had sustained any loss of blood.
By varying the diet from elimination of one factor to elimination of all but one factor therein, the speed of regeneration of blood was changed, but with each diet the organism replenished its normal supply of blood to the original values for red cells and hemoglobin.
Protein permitted more rapid blood regeneration than either carbo hydrate or fat when fed as a sole nutrient grams daily).
The diets of vitamin-rich food, even in very small amounts, gave somewhat more speedy regeneration than any other diet containing one food factor only.
This study of blood regeneration has not covered the effect of iron on blood formation. Work on this phase of the problem is now being carried out.
I desire, to express my sincere thanks to Prof. Lafayette B. Mendel who outlined this problem, for his suggestions and interest throughout the investigation.
