Rabbits were exposed to a hot environment, 42 to 45°C. for one hour, and the arterial blood was taken before and after the exposure. O2-and CO2-content, alkali reserve, hematocrit, hemoglobin concentration and pH were examined.
The following results were obtained:
1. In rabbits exposed to hot environmemt, rectal temperature were elevated, O2-content decreased, CO2-content decreased, Sa-O2 slightly increased, alkali-reserve markedly decreased, Hb-content and Ht increased, and pH of whole blood decreased.
2. Parenteral administration of V.B1, V.C, Cortisone, and sodium citrate were all effective in correcting the adove mentioned changes of bood-gases of rabbits exposed to hot environment.
3. V.B1 and sodium citrate were more effective in correcting the changes of blood gases.
4. Beneficial effect on Hb-content and Ht were most manrked in cases of cortisone, and less in cases of V.B1 and V.C. and much less in cases of sodium citrate.
