Background/Aims: The presence of pleural effusion has been proposed as a marker for severe pancreatitis. There is a controversy about whether pleural effusion in acute pancreatitis is associated with severity of the disease. The aim of this study was to clarify the association between pleural effusion and severity in patients with acute pancreatitis. Methods: We retrospectively evaluated 216 patients (M:137, F:77) with acute pancreatitis. The diagnosis of acute pancreatitis was based on the typical signs and symptoms, enzyme elevation, and radiological findings, For grading of the severity, APACHE II and Ranson score at admission were used. The patients were subdivided into four etiological groups: alcohol, gallstone, idiopathic and others. Results: Pleural effusion was observed in 46 (21.3%) out of 216 patients with pancreatitis. Alcohol was the most common etiology (41.3%), followed by gallstones (32.6%), idiopathic (17.4%) and others (8.7%). The location of pleural effusion was not correlated with severity of pancreatitis. The rate of high ransor score (>3) in the patients with pleural effusion was significantly higher than that in the patients without pleural effusion. However, there was no significant difference between the patients with and without pleural effusion when APACHE II score was applied. The mortality was 4.7% in patients with pleural effusion and 4,4% in patients without pleural effusion. Conclusions: Pleural effusion is considered as a useful predictor of severity and a negative parameter for the course of the acute pancreatitis. (Kor J Gastroenterol 1998;32:230 - 235)

Background/Aims: The sphincter of Oddi motor activity is modulated by multifactorial and various neural and hormonal factors. However, it has not been studied whether 5-HT3 receptor antagonist modulate the sphincter of Oddi motor activity. The aim of this study was to confirm the presence of 5-HT on the sphincter of Oddi and to investigate the role of 5-HT3 receptor antagonist in the regulation of motor activity of the sphincter of Oddi in human using ERCP manometry. Methods: The motor activity of sphincter of Oddi was examined using ERCP manometry before and after intravenous bolus injection of a selective 5-HT3 receptor antagonist (Ondansetron), 8 mg, in 30 study subjects. To confirm the presence of 5-HT in sphincter of Oddi, immunohistochemical stain was done using resected specimen of ampulla of Vater. Results: On immunohistochemical staining, we confirm the expression of 5-HT in the normal duodenal mucosa (16 cells/HPF). Ampullary mucosa showed weakly positive stain for 5-HT using anti 5-HT (1.4 cell/HPF). Basal pressure of the sphincter of Oddi was significantly reduced by injection of ondansetron from 10.7+-0.8 to 8.8+-0.7 mmHg. Amplitude of phasic contraction was also significantly reduced from 82.9+-10.9 to 65.4+-10.5 mmHg. Although frequency of phasic contraction was slightly reduced from 3.1+-0.6 to 2.5+-0.4/min, it was not statistically significant. Conclusions: These findings suggest that 5-HT3 receptor antagonist has inhibitory effects on the sphincter of Oddi motor activity. (Korean J Gastroenterol 1998;31:532 - 540)

The purpose of this study was to investigate the effects of 8 week training program on immunoglobulins(IgA, IgG, IgM). Fourteen mentally retarded men were participated in this study and were assigned to two groups(experimental; n=7 and control groups; n=7). Their intelligent quotients were shown from 45 to 55. Training program consisted of aerobic exercise, weight training. All variables were measured before and after training. Before and after the intervention, each subject took cycle ergometer test under controlled laboratory condition. All exercise sessions took place on a bicycle ergometer (@ 50 RPM), performing 4 minutes of cycling at 2kp to reach targeted heart rate (70-80%/max) then, continued for 20 minutes. Blood samples were obtained before, immediate exercise. IgA did not change with acute and chronic exercise both experimental and control group. There was significant interaction between groups and exercise training in IgG, so blood IgG concentrations increased significantly with submaximal exercise and this exercise induced increase was more higher in exercise training group than control group(p=.049). IgM showed no significant change with training and acute exercise. In conclusion, chronic exercise partially increased blood immunoglobulins concentration (IgG) after submaximal exercise. Further study needed to elucidate the exact mechanism related to chronic exercise and immune function on other immune parameter and different exercise intensity, physical fitness.
