BACKGROUND: Obesity is linked to a wide range of respiratory diseases. Several studies have shown that body weight at baseline and weight change were related to pulmonary function. The purpose of this study was to investigate the relationship between change in body mass index (BMI) and pulmonary function in adults. METHODS: Of those aged 40-64 years at baseline who had initially visited the health promotion center at one university-level hospital from January 2000 to December 2002, 499 (men: 309, women: 190) patients revisited the center over a 5-year period up to December 2009 and were enrolled in the study. Subjects were classified into 4 groups- group 1: normal-normal, group 2: normal-obese, group 3: obese-normal, and group 4: obese-obese, based on their BMI at baseline and follow-up. Forced expiratory volume in one second (FEV1), forced vital capacity (FVC) and FEV1/FVC were measured by spirometry. RESULTS: Change in FEV1/FVC was significantly associated with change in BMI for men in all 4 groups. Change in FEV1/FVC was significantly different between group 1 and 3 and between group 1 and 4. Changes in FEV1, FVC and FEV1/FVC were significantly associated with change in BMI for women in all 4 groups. Change in FEV1 was significantly different between group 3 and 4, and change in FVC was significantly different between group 1 and 3. CONCLUSIONS: These results suggest that a change in BMI is negatively associated with change in pulmonary function. Obesity itself can be a risk factor for pulmonary dysfunction, and a decrease in BMI through weight reduction could reduce pulmonary dysfunction or improve pulmonary function in adults.

PURPOSE: This study describes the CT and MR findings of mucoceles occurred in the post-operative maxillary sinuses. MATERIALS AND METHODS: CT and/or MR of 19 maxillary mucoceles in 16 patients who had been operated by CaldwelI-Luc procedure were reviewed. CT scans were performed after contrast enhancement in axial and coronal planes with 5mm thickness. Three cases were studied with a 2.0 T or 0.5 T MRI, which demonstrated multi-compartment lesions. RESULTS: The lesions were bilateral in 3 cases. Compartmentalization of the antral cavity was seen in 7 out of 19 involved sinuses. Surgical bone defect of the anterior wall was the most frequent route of extension (11 cases) and extension into the infratemporal fossa with erosion of posterolateral wall was seen in 7 lesions. In 6 cases, the lesions involved orbit. The expansile and erosive bone changes were localized in every case. In one case with multi-compartment lesion, both T1- and T2-weighted MR images showed different signal intensities in each compartment which represented different protein concentration. CONCLUSION: Post-operative maxillary mucocele showed CT findings of localized erosion and bulging most frequently at the anterior wall in which the bone windows were made during the previous surgery. Post-operative compartmentalization of maxillary antrum may cause eccentric expansion of mucocete and each compartment may show different signal intensities on MR.

A cholecystectomy is one of the most frequent operations in the field of surgery. Recently, a laparoscopic cholecystectomy (LC) has become a commonly performed procedure for treatment of gallbadder disease, mainly gallstone disease. It has the advantages of less postoperative pain, fewer complications, and more rapid recovery. There is no doubt that LC will be the first choice for the treatment of gallbladder disease. We performed this study to research problem and to improve the successbility of this operation. We analyzed 300 patients who underwent a laparoscopic cholecystectomy from January 1, 1993 to December 31, 1996, at the Department of Surgery, College of Medicine, Pusan National University. The main results are as follows:1) The age range of the patients was from 17 to 72 years. There were 104 males and 196 females. 2) The most common previous operation was an appendectomy; the second most common was pelvic surgery. 3) The common chief complaints were right upper guadrant pain and indigestion. 4) Radiologic finding showed, gallstones in 212 cases and polyps in 30 cases. 5) The removed stones varied in size and number. 6) Postopertive complications were puncture site infection, bile leakage, pulmonary complications, etc. 7) The mean postopertive hospital stay was 4.2 days. 8) Intraoperative conversion to an open cholecystectomy was due to severe inflammation, adhesion, bleeding, etc. In conclusion, resolution of technical difficulties, meticulous training and experience, proper patient selection, and more developed tools are required.

Caffeine has been known to induce the contraction of rabbit aortic ring resulting from Ca2+ release from the intracellular stores. But in contrast, contraction of aortic ring induced by depolarizing agents or agonist was reported to be suppressed by caffeine. The present study was intended to examine the effect of caffeine on Ca2+ movement across the plasma membrane and actomyosin ATPase activity of vascular smooth muscle to elucidate the modes of action of caffeine on the vascular smooth muscle. Aortic ring preparation were made from the rabbit thoracic aorta and the endothelial cells were removed from the ring by gentle rubbing. The contractilty of the aortic ring was measured under varying conditions, and Ca2+ influx across the membranes of the aortic ring was measured with Ca2+ sensitive electrode with and without caffeine and the effect of caffeine on actomyosin ATPase activity were measured by modified Hartshrone's method. 45Ca wash out curves with and without caffeine were studied by Richard's method. The results were summarized as follows: 1) Caffeine inhibited the contractilty induced by norepinephrine. high K+, and histamine. but caffeine alone induced a transient contraction of vascular smooth muscle. The caffeine induced contraction was demonstrable even in the absence of external Ca2+. 2) Caffeine increased 45Ca efflux from vascular smooth muscle. 3) In the presence of propranolol, the inhibitory effect of caffeine on epinephrine induced contraction still persisted. 4) Caffeine decreased norepinephrine induced Ca2+ influx through the plasma membranes of aortic ring. 5) Caffeine decreased the actomyosin ATPase activity of vascular smooth muscle. From the above results, it is suggested that caffeine induces the contraction of vascular smooth muscle by release of Ca2+ from intracellular Ca2+ stone, but inhibits drug-induced contraction by decrease of Ca2+ influx across the plasma membranes and a decreased Ca2+ sensitivity of contractile protein in vascular smooth muscle.

Primary tumors of the heart are rare, three quarter of the tumors are benign, and nearly half of the benign heart tumors are myxomas. Cardiac myxoma usually originate in the left atrium about 75 percent, however, only 3 to 4 percent of myxoma are detected in the left ventricle. We report on a 32 years old woman with left ventricular myxoma who presented with shortness of breath, chest tightness, and general weakness. Acute pulmonary embolism and left ventricular myxoma were found on a perfusion lung scan and echocadiogram. A mass located on septal wall of left ventricle was excised en bloc. The patient recovered uneventfully and careful follow up has be performed periodically.

Behavior-modification approaches are among the most widely used methods for losing weight. The most important concern in these approaches is that the client is helped to achieve long-term weight loss. The purpose of this study was to determine the effectiveness of nutritional counseling for weight reduction in office workers. Sixteen overweight office workers (BMI=25.8+/-.5 age=34.1+/-.0) were selected from Poscohuls. Prior to nutritional counseling, their dietary intakes were assessed using the 24-hour recall method, and survey questionnaires for lifestyle and dietary habits were collected. Nutrient intakes were calculated using the Food Processor II program modified for Korean foods. Nutritional counseling sessions were conducted every 2-3 weeks for 5 months. Various techniques tailored to the individual participants were used to facilitate weight loss. After 5 to 6 counseling sessions, questionnaires for lifestyle and dietary habits were re-evaluated. Daily energy intake showed great individual differences. The energy intake of every client decreased by about 15% (p=0.08). Fat consumption was lowered by 39.3%, but consumption of carbohydrate and protein was not changed. The common dietary and lifestyles problems were overeating, binges, dinning out, snacking, and drinking alcohol. Before counseling began, clients ate out an average of 2.8 times per week, and they ate high-fat foods such as belly pork. After counseling, they consumed low-fat dishes such as fish and lean meat in fewer dinning-out sessions. Also, the number of binges decreased slightly, and clients consumed smaller meals. Similar changes occurred with respect to the consumption of alcohol. During the counseling sessions, 25 percent of clients lost weight by approximately 2kg, while 75 percent maintained their weight. In conclusion, multiple nutritional counseling sessions are an effective and efficient approach to change eating pattern to keep losing weight. Furthermore, through multiple nutritional counseling sessions, clients can gain good dietary habits and learn to control their weight through behavior modification. However, clients need to have patience and trust to lose weight since it takes longer periods to show losing weight multiple nutritional counseling sessions.
