N/A To investigate the correlation of esophageal symptoms w ith esophageal manometric parameters in patients with progressive systemic sclerosis (PSS) we tested esophageal motility in 10 patients with PSS who were admitted to Seoul National University Hospital from Feb. 1988 to Aug. 1988 and in 5 normal subjects, and we analyzed every parameters. The results were as follows: 1) 4 patients with esophageal symptoms showed marked decrease of lower esophageal sphincter pressure (LESP) (9.I+4.4 mmHg vs 27.9+8.5 mmHg; p< 0.005) while 6 patients having no esophageal symptoms showed normal LESP (29.4+4.0 mmHg vs 27.9+8.5 mmHg). 2) Normally propagating peristaltic waves were not found in the lower esophageal bodies of 4 patients who had esophagea] symptoms. On the other hand, among 6 patients without symptoms, 3 patients showed no propagating peristaltic waves while the other 3 patients showed normally propagating peristaltic waves in the lower esophagus. 3) The amplitudes of contraction waves at upper esophageal body of patients with esophageal symptoms were decreased compared with those of patients who had no esophageal symptom. (29.0+6.1 mmHg vs 21.0+4.4 mmHg; p<0.05) 4) In cases not showing normally propagating peristaltic waves, nonpropagating, hroad-based, low-amplitude contractions were found at the lower esophageal body. In conclusion, LESP is the esophageal manornetric parameter vhich seemed to be the most closely correlated with esophagea) symptoms in patients with PSS. And PSS seems to influence the upper esophageal contraction. Our data also indicates that esophageal manometry may be useful in the early detection of esophageal involvement in patients with PSS.

N/A The effect of intestinal bacterial overgrowth on brush border hydrolases and composition of mucus was studied in rats with surgically introduced jejunal self-filling blind 1oops (SFBL), Enzymes and mucus were analyzed from blind loop segments, segments above and below the blind loops in the rats with SFBL, and three corresponding segments in the nonoperated controls. Sucrase and lactase activities were significantly reduced in homogenates from the self-filling blind loop, but alkaline phosphatase was not affected. Lactase activities were significantly reduced in homogenates from the three segments (proximal, blind loop, distal) of small intestine of rats with SFBL. The carbohydrate content of purified mucin was reduced in rats with SFBL than that of normal controls. N-acetyl neuraminic acid was significantly reduced in purified mucin from the SFBL. The results indicate that bacteria enhance the destruction of intestinal surface glycoproteins including disaccharidases. Since alkaline phosphatase, a glycoprotein, is not affected, the destruction is selective and presumably involves only the most exposed membrane components. And among disaccharidases, lactase activities were depressed in segments without direct contact with bacteria, suggesting that bacterial byproducts may exert effect on lactase synthesis systematically.
