The meals contained similar amounts of digestible carbohydrates, fat and protein. The gastric emptying rate of the meal containing sodium alginate, measured by detection of 51Cr mixed into the meals, was significantly slower than that of the fiber-free meal. Sodium alginate also induced significantly lower postprandial rises in blood glucose, serum insulin and plasma C-peptide. The diminished glucose response after the addition of sodium alginate could be correlated to the delayed gastric emptying rate induced by the fiber (rs = 0.92, P less than 0.01)

The decay of /sub 86//sup 209/Rn/sub 123/ to levels in /sub 85//sup 209/At/sub 124/

The decay of /sup 209/Rn to levels in /sup 209/At has been investigated. Gamma rays were studied in singles and coincidences using Ge(Li) detectors. Conversion electrons were recorded with a Si (Li) detector. A decay scheme is suggested, indicating electron capture branches to positive parity states at 1954, 2136 and 2415 keV. These states are interpreted in terms of core excitations in conformity with the /sup 207/Bi isotone. Two levels at 408 and 746 ke V, tentatively assigned spin 7/2/sup -/, are fed by electron capture with log ft values of 6.8 and 6.4 respectively. (16 refs)
