The American Journal of Digestive Diseases Aims and scope Submit manuscript

Summary

Gastric and small-intestinal contents of normal human subjects were analyzed for sodium, potassium, calcium, chloride, bile salts, osmolality, pH, and-for polyethylene glycol (if this volume indicator was included in the test meal) following the ingestion of 2 meals. From the results, osmotic constituents of
