Very few data are available about Zn in gastrointestinal fluids in humans. To obtain data in one such fluid Zn was measured in plasma and gastric fluid, obtained by direct visual aspiration through an endoscope placed into the gastric fundus, in 36 subjects with normal gastrointestinal mucosa (N) and in 36 patients with the following upper gastrointestinal pathology confirmed by endoscopy: 13 with esophagitis (E), 9 with gastritis (G) and 14 with duodenal ulcer disease (DU). Plasma and gastric fluid Zn were estimated by flame atomic absorption spectrophotometry. Mean plasma Zn was significantly lower than normal in patients with E (N, 87 +/- 2 ..mu..g/dl, M +/- SEM; E, 75 +/- 4, p < 0.01) but plasma values were similar to normal in the other patient groups (G, 89 +/- 4; DU, 87 +/- 2). Mean gastric fluid zinc in G was significantly higher than in normal subjects (G, 664 +/- 159 ..mu..g/L; N, 360 +/- 43, p < 0.02) but not significantly different from normal in patients with DU or E (DU, 402 +/- 76; E, 307 +/- 55). Mean gastric fluid Zn in women with DU was approximately 45% higher than in men with DU, although it was 17% lower in normal women than in normal men. Compared to other normal tissues gastric fluid Zn is about 1/3 that in serum and about 3 times that in saliva. These results indicate that Zn in plasma and gastric fluid is altered in some upper gastrointestinal diseases.
