N/A Objectives: Despite the fact that determinations of cadiorespiratory fitness levels by exercise stress tests are becoming widely used in healthy individuals as well as in patients with cardiopulmonary diseases, the normal standards in this field have not been well established in Korea. The purpose of this study is to provide normal standards or reference values for the VO2 max, HR max and O2 pulse max for normal Korean adults by age and sex, along with the derivation of regression formulae of these parameters. Methods: In 1,000 healthy adults (20-66years) consisting of 603men and 397women, symptomlimited maximal exercise was carried out by Bruce protocol, allowing holding on to the hand rail of the treadmill during exercise for the safety purpose. All the subjects were non-athletes and were members of a health center and were more conscious about their health and physical fitness than the ordinary population. Results: The VO2 max and HR max were decreased with age as expected and, as a whole, the values of the VO2 max and HR max of females were approximately 84% and 90% of those of males, respectively. Estimated yearly reductions in the V max for males and females were 0.45 and 0.32mL/kg/min, respectively and those of the HR max were 0.72 and 0.76/min, respectively. The O2 pulse max of the female was approximately 70% of that of the male, and was slightly related to weight and exercise time. The regression equations of the parameters obtained using exercise time (ET, sec), age (A, year), weight (W, kg) and sex (S, O=male; 1= female) were: HR max=215.3-0.74A-5,04S, O2 pulse max= 5.371+0.216W+0.0107ET-1.505S and VO2 max=40.612+1.950ET-0.206A-0.147W-6.060S, Conclusion: The VO2 max in our study was higher than hitherto reported. This was primarily due to longer exercise time of the subjects on the treadmill, because they were allowed to hold on to the hand rail during exercise. And also, the fact that our subjects, being members of a health center, might have had higher physical fitness levels than general population could have contributed to the high VO2 max. Thus, we feel that our results could be the ideal target or- reference values to be achieved for those patients or individuals who have to do the tests with holding on to the rail of a treadmill for safety purpose.

The Peutz-Jeghers syndrome is an autosornal dominant condition characterized by mucocutaneous pigmentation and hamartomatous polyps of the gastrointestinal tract. This syndrome is clinically important because of complications caused by gastrointestinal polyps, such as abdorninal pain, gastrointestinal bleeding and intussusception often leading to intestinal obstruction. The possibility of malignant change in the polyp has been a controversial issue. In the recent reviews of soe cases of Peutz-Jeghers syndrome, the reported lesions of small intestinal adenocarcinoma are regarded as the benign process of enteritis cystica profunda. We present herein a case of Peutz-Jeghers syndrome with small bowel perforation, a previously unreported instance, and enteritis cystica profunda. (Korean J Gastroenterol 1997; 29:677-682)

N/A Background/Aims: This study was performed to investigate the relationship between Helicobacter pylori infection and degree of gastric mucosal inflammation, IgG antibody titer against H. pylori, and fasting serum gastrin level. Methods: Patients were divided into 2 groups(H. pylori positive and negative) by identification of H. pylori in biopsied specimens with special staining. In H. pylori positive group, the density of gastric K. pylori colonization was further graded semiquantitatively from 1 to 3. The severity of gastritis in each group was scored according to the Sydney system from 0 to 3. Serum IgG antibody titer against H. pylori was detected by second-generation antigen based enzyme immunoassay(Cobas Core Anti-Helicobacter pylori EIA). Fasting serum gastrin level was measured by standard radioimmunoassay technique. Results: The severity of gastritis in H. pylori positive group was significantly higher than H. pylori negative group in mononuclear cell infiltration(pC0.001), activity of PMNL(pC0.001), and glandular atrophy(pC0.01). In H. pylori positive group, the density of H. pylori colonization was significantly correlated with mononuclear cell infiltration(r=0.67, p0.001), activity of PMNL(r=0.70, p0.001), and grandular atrophy (r=0.38, pC0.001). Neither density of H. pylori colonization nor severity of gastritis was correlated with fasting gastrin level and IgG antibody titer against H. pylori. Conclusions: H. pylori infection results in localized inflammatory reaction in gastric mucosa with relation to density of H. pylori colonization, but serum H. pylori IgG antibody titer does not reflect the severity of gastritis. Fasting serum gastrin level also has no relation with the density of H. pylori colonization and severity of gastritis. These findings suggest that the factor which cause inflammation in gastric mucosa may be different from that cause gastrin secretion or formation of IgG antibody.

Pancreatic and intra-abdominal fat necrosis are frequently in chronic pancreatitis, but fat necrosis of the bone marrow has been rarely reported. These extrapancreatic fat necrosis occur by circulating lipolytic enzymes. We report a case of multiple fat necrosis of the osseous medulla and skin associated with chronic recurrent pancreatitis.
