実験的飢餓時における栄養素投与による臓器酵素作用の影響について

The author has conducted the experiment classifying some rabbits into four groups: 1) the group of complete starvation, 2) the group of incomplete starvation being administrated mononutriment, 3) the group of incomplete starvation being administerated two kinds of nutriment, 4) the group of prolonged incomplete starvation being administrated mononutriment at the end of complete starvation. The author, then, examined whether a few hydrolytic enzymic actions in organs at the time of starvation would be effected by administrating nutriment, and arrived at the following results: 1) It is methionin that prolongs the living days most under starvation. 2) The group of the highest degree of decline in weight is that of the longest one in life time. 3) In view of increase or decrease of weight ratio in organs, there is some connections of administrating methionin and V B(1) with the decrease in liver and lung at the time of starvation and of administrating olive oil with the decrease in heart. 4) Amylase action of liver at the time of starvation is increased by administerating methionin. 5) Under incomplete starvation by giving mononutriment, the administration of methionin can be able to control the decline of catheptase action of liver. 6) Phosphatase action of kidney at the time of starvation is increased by administrating glucose. 7) In these experiments of starvation, the total amount of urinic nitrogen generally increases before death.
