Paradoxical survival of elderly men with high blood pressure.

confirmed these findings and showed a 19% reduction in stool output with oral rehydration solution containing glucose and glycine compared with the standard oral rehydration solution.6 On the other hand, results from six studies in children under 3 years with acute diarrhoea, including diarrhoea associated with rotavirus, showed that the addition of glycine and, in some studies, glycyl-glycine to glucose oral rehydration solution had no consistent beneficial effect on the stool output, intake of oral rehydration solution, or duration of diarrhoea.6202' Our results support the concept that absorption of sodium and water can be increased significantly by adding an amino acid to the oral rehydration solution. Before a new formula for oral rehydration solution is proposed, however, several studies should be conducted to determine the efficacy of the new solution in treating diarrhoea of various origins in young children; the optimal osmolality of the solution and the optimal amino acid concentration; and whether other amino acids might be even more efficacious than alanine in promoting absorption of salts and water.
