To define the histology of the columnarlined esophagus, we obtained esophageal biopsies from various levels with manometric control from 11 patients. There were three types of columnar epithelia above the lower esophageal sphincter: atrophic gastric-fundic-type epithelium with parietal and chief cells; junctional-type epithelium with cardiac mucous glands;(More)
The case of a patient with primary mesenteric venous thrombosis presenting with massive dilatation of almost the entire colon is described. The differential diagnosis suggested by this presentation is briefly discussed with special attention to the diagnosis of acute colonic pseudoobstruction. Possible reasons for the atypical presentation of acute(More)
Incorporation of L-leucine-(14)C into proteins and immunoglobulins in vitro was determined in jejunal biopsy specimens from normal volunteers, patients with celiac sprue before and after introduction of gluten into the diet, patients with Whipple's disease in remission, and patients with immune deficiency states. Values for incorporation of L-leucine-(14)C(More)
We investigated the effect of pyridoxine administration in three patients with homocystinuria due to cystathionine synthase deficiency. The drug decreased the plasma concentration and urinary excretion of methionine and homocystine and the urinary excretion of homolanthionine and the homocysteine-cysteine mixed disulfide. Urinary cystine rose somewhat. Oral(More)
Colloid osmotic pressure was measured at birth in 102 newborns. Umbilical vein plasma colloid osmotic pressure correlated with total serum protein, birth weight, and gestational age. Mean colloid osmotic pressure of 11 infants who were small for gestational age was less than, and that of seven infants who were large for gestational age was more than, that(More)
The effect of fasting on gallbladder opacification during oral cholecystography was studied in 10 normal volunteers using 2 oral cholecystographic agents, iopanoic acid and sodium tryopanoate. Radiographs made 15 hours after ingestion of the contrast agents revealed good opacification of the gallbladder in all subjects when iopanoic acid was administered(More)
(1) Solubilization of Telepaque in the intestine is a limiting factor in the rate of intestinal absorption. Bilopaque and Oragrafin are more water-soluble and appear to be better absorbed than Telepaque. (2) Bile salts in the intestinal lumen increase the solubility of Telepaque. Therefore, a fatty meal administered with the Telepaque is desirable to(More)
