Abstract
Summarizing the results of the above experiments, it was learnt that, under urethane anesthesia, the absorption patterns of calcium are almost the same as those of under non-anesthetic condition in the cases of oral administration, duodenal infusion and enema of calcium chloride solution, and that urethane itself was considered not to have exercised any influences on the calcium absorption. Similarly to the case of urethane, under anesthetic condition with chloral hydrate or magnesium sulfate, the calcium absorption in the large intestine was not generally influenced. Kondo reported that, the combined enema with chloral hydrate enhances remarkably the calcium absorption in the large intestine, but not with magnesium sulfate. In view of the above fact, it was clarified that the calcium absorption in the large intestine is greatly influenced by the combined enema of appropriate narcotic and calcium preparation.
is similarly enhanced by the combined enema with urethane.
