| galactose tolerance test | A liver function test, based on the ability of the liver to convert galactose to glycogen, measured by the rate of excretion of galactose following ingestion or intravenous injection of a known amount; normally, less than 3 g appear in the urine within 5 hours after the ingestion of 40 g.

| adult-onset diabetes | <disease> An often mild form of diabetes mellitus of gradual onset, usually in obese individuals over age 35; absolute plasma insulin levels are normal to high, but relatively low in relation to plasma glucose levels; ketoacidosis is rare, but hyperosmolar coma can occur; responds well to dietary regulation and/or oral hypoglycaemic agents, but diabetic complications and degenerative changes can develop. (05 Mar 2000) |
| alimentary diabetes | Glycosuria developing after the ingestion of a moderate amount of sugar or starch, which normally is disposed of without appearing in the urine, because rate of intestinal absorption exceeds capacity of the liver and the other tissues to remove the glucose, thus allowing blood glucose levels to become high enough for renal excretion to occur. Synonym: alimentary diabetes, digestive glycosuria. (05 Mar 2000) |
| alloxan diabetes | Experimental diabetes mellitus produced in animals by the administration of alloxan, which damages the insulin-producing islet cells of the pancreas. (05 Mar 2000) |
