In the living animal containing cesium-137 it has been shown there is a metabolic dissociation of the radioactive daughter barium -137m. This means that some tissues such as bone and plasma will have a significantly increased level of barium -137m as compared with that expected from the usual radioassay measuremenis of cesium -137. The technique of peritoneal lavage was used to study metabolic processes involved in the removal of alkaline earths from bone. Methods have been established for studying the fuctors thnt govern the movemeni of alkaline earths from the digestive tract to the body. Special atteniion is being given to the ability of certain sugars to enhance gastroiniestinal absorption. Lactose and xylose increased strontium absorption more than that of calcium. The enhancing effect of lactose occurred mainly in the small intestine, and there is a suggestion that an active transport process is involved. Lactose also tended to decrease the emptying rate of the stomach. (auth)
