Alkaline phosphatase activity of rat serum was reduced 50% by fasting the animal for 24 hours. Diabetes, induced by alloxan or streptozotocin, increased serum alkaline phosphatase 3- to 5-fold in fed rats and the elevated activity was reduced by insulin administration. In the absence of insulin, fasting alone was able to reduce the serum alkaline phosphatase of diabetic rats to control values. The elevated serum isozyme was found to be of intestinal origin by the use of appropriate inhibitors and electrophoretic mobility following neuraminidase treatment. It is concluded that food intake, particularly the hyperphagia of diabetes, plays a major role in regulating the concentration of intestine and serum alkaline phosphatase in the rat.

A 3-year-old girl of Navajo heritage had intractable diarrhea beginning at 4 days of age and resulting in long-term hyperalimentation. Investigation before multivisceral transplantation included biopsies of the rectum, stomach, duodenum, and liver. The diagnosis of microvillus inclusion disease was established by documentation of microvillus inclusions in duodenal epithelial cells. A trial of somatostatin therapy was ineffective in controlling the diarrhea. Subsequently, a multivisceral organ transplant provided a unique opportunity to establish the gastrointestinal extent of involvement of this disease. Ultrastructural microvillus inclusions were identified in the duodenum, jejunum, ileum, and colon, but not in the gallbladder. A few inclusions also were documented in gastric antral epithelial cells. Alkaline phosphatase stains performed on paraffin-embedded material showed a few inclusions in the antrum of the stomach and many inclusions throughout the small intestine, primarily in surface epithelial cells but also in upper crypt cells.
