The purpose of this study was to investigate the influence of regular stretching exercise for 1 year on health related fitness of the elderly women. We also determined whether the weekly stretching exercise sessions followed by intensive stretching exercise program was beneficial to maintain the altered health related fitness status. The thirty elderly women (F, 80.1+/-6.6 yr) were participated in this study. Subjects had no serious orthopedic problems. During the study period, they did not perform any regular physical activity beside the stretching exercise. The 1 year stretching exercise programs included 3 days/week stretching exercise session for the first 12 weeks followed by 1 day/week stretching exercise for rest of the study period. The subjects were tested 6 categories of health related fitness factors which included % body fat, flexibility, hand grips, back strength, balance, and agility. The summary of the results of this study were as followed: 1) There were significant increase in FFM and slightly decrease in %BF and WHR after the 3 days/wk stretching exercise program. However, there were significant decrease in FFM and WHR after the 1 day/wk stretching exercise program (p<.05). 2) There were significant increase in flexibility, hand grip strength (Rt.) and balance after the 3 days/wk stretching exercise (p<.05) while hand grip strength (Lt.) and back strength were slightly increase after the exercise. However, there were significant decrease in hand grip strength (both) and reaction time after 1 day/wk stretching exercise program while flexibility, back strength, and balance were slighly decrease after the program. In conclusion, this study showed that the 3 days/wk stretching exercise for 12 weeks result in significant increase of all health related fitness factors (p<.05). However, it showed that some of the HRF factors were decreased after the weekly stretching exercise unexpectedly.

Superficial gastritis has been classified as a type of chronic gastritis, since a report of Schindler in GASTRLTIS, 1947. Howev~er, Benedict reported that superficial gastritis is only acute gastritis or shows normal mucosa histologically. The com mon endopical findings of chronic superficial gastritis were adherent mucus, edema, redness. The common redness which were encounterd are patchy redness and comb-like redness(Kammrotung). We studied the relationship between the redness of superficial gastritis and acute inflammatory changes histologically. Each case of superfieial gastritis was biopsied to redening and non-redening mucosa respectively. We collected 24 cases with 48 biopsy specimens. The results are as follows: Acute inflammatory changes were found only one case in redness and none in non-redness groups. There was no difference in acute inflammatory changes in two groups. The degree of mucosal atrophy were 62.5%, 66.7% in normal mucosa, 12.5%, 16.7~% in mild atrophy, 25%, 12.5% in moderate atrophy, 0%, 4.l% in severe atrophy with respect to redness and non-redness mucosa respectively. There was no difference in degree of mucosal atrophy in two groups. Mucosal atrophies were higher in older ages above 41 years old than below 40 and with increasing age, there was increasing tendency of mucosal atrophy. In conclusion, There was no relationships between mucosal redness and acute in flammatory changes histologically and also between mucosal redness and degree of atrophy.

Complete decompression is very important for the surgical treatment of the spinal stenosis. But it may produce the segmental instability or spondylolisthesis as postoperative complications. So rigid internal fixation is mandatory to reduce this problem. Authors treated 16 cases of spinal stenosis by complete decompression and pedicale screw fixation and posterolateral fusion, analyzed 11 cases which were followed more than 9 months. The results were as follows: 1. Among the 11 cases, the mean age was 49 years old and there were 5 males and 6 females. 2. The most common cause was degenerative type, 7 cases. The most frequent level of involvement was L4–L5, 10 cases and two level involvement was 3 cases. 3. Among the 11 cases, 6 cases were excellent and 4 cases were good, and 1 case was fair, in Hanley's criteria. 4. In spondylolisthetic stenosis, the average percentage of slippage was changed from 22% pre-operatively to 2.7% postoperatively and 3.8% after 9 months follow up. 5. The complications were relatively few(1 case of hematoma and 3 cases of pain on the bone graft donor site).

The talus is a bone with unique biomechanical features and vascular supply. Although fractures of the talus are not common, the complications of the displaced fractures or dislocation are frequent and resulting disabilities are so severe that the importance of proper management is emphasized. Authors analyzed 17 cases of fracture-dislocation of the talus, treated at Soon Chun Hyang University Hospital from January 1983 to December 1988. The results were as follows:l. Among the 17 cases, there were 15 males and 2 females and the average age was 28 years old, ranged from 21 years to 58 years. 2. The causes were fall from height in 10 cases, traffic accident in 6 and others in one. 3. According to Marti-Weber classification, 2 cases were type I, 5 in type II, 7 in type III and 3 type IV. 4. Among the 17 cases, 9 cases in type I and II were treated conservatively, and 8 cases in thpe III and IV were treated operatively. 5. Complications were avascular necrosis in 3 cases, degenerative arthritis in 4 and nonunion in 1. 6. Final results, evaluated by the criteria of Mindell et al., were as follows: excellent in 7 cases, good in 5, fair in 3 and poor in 2.

PURPOSE: To assess the performance of the dynamic contour tonometer (DCT) in eyes undergoing excimer laser photorefractive keratectomy (PRK). METHODS: Intraocular pressure (IOP) was measured in 30 eyes after first time excimer laser PRK pre and three months post operatively using Goldmann applanation tonometer (GAT), noncontact air tonometer (NCT), and the DCT. RESULTS: There was significant correlation between central corneal thickness (CCT) and IOP measurements by GAT and NCT (CCT vs GAT: r2=0.31, p<0.01, CCT vs NCT: r2=0.39, p<0.01). However, the correlation between CCT and IOP measurements by DCT was not significant (CCT vs DCT: r2=0.14, p=0.32). After PRK, the mean change in CCT and IOP measurements using GAT, NCT, DCT were 73.70+/-26.92 micrometer (mean+/-SD), 2.43+/-2.86 mmHg (p<0.01), 3.83+/-2.34 mmHg (p<0.01) and 0.44+/-1.51 mmHg (p=0.125), respectively. The preoperative and postoperative DCT measurements did not differ significantly. CONCLUSIONS: The reduction in CCT induced by PRK doesn't appear to influence DCT measurements; therefore, DCT may be better suited over GAT or NCT for monitoring IOP in eyes that underwent refractive surgery.

PURPOSE: The purpose of this study was to evaluate the clinical outcomes and radiologic findings of primary total hip arthroplasty (THA) using cemented polished femoral stems. MATERIALS AND METHODS: We retrospectively reviewed 91 hips (91 patients) that had undergone primary THA with cemented polished femoral stems who were followed for at least 10 years. The mean age at surgery was 57 years (47-75 years). Mean follow up period was 12.8 years (10.1-14.0 years). Harris Hip Score (HHS) was used for clinical evaluation. Radiologic evaluation was focused on cementing technique including subsidence within the cement mantle, radiolucent lines at the cement-bone or cement-stem interface, cortical hypertrophy, and calcar resorption. RESULTS: The average HHS was 55.2 points before the surgery that improved to an average of 93.2 points at the final follow-up. According to Barrack classification, there were 50, 32, and 9 cases in A, B, and C grades, respectively. Subsidence of femoral stem was less than 2 mm except in one patient. There were no progressing radiolucent line or loosening of the femoral stem. CONCLUSION: In this study, THA using cemented polished femoral stems was found to have favorable outcomes in long term follow-up.

Intestinal tuberculosis has been known since antiquity. After about 1950's, effective antituberculous chemotherapy and an improved standard of living resulted in a steady decline in all forms of tuberculosis. However, intestinal tuberculosis has been reported with impressive frequency in developing countries including Korea. Disease affecting the duodenum is reported to be rare and isolated duodenal tuberculosis sparing the rest of the intestine is uncommon. We experienced a case of tuberculosis of duodenal bulb associated pulmonary tuberculosis. The diagnosis was made on the basis of the histological study of the endoscopic biopsy specimen. We have confirmed the healing of the duodenal lesion by the follow-up endoscopy after 9 months treatment of antituberculous medication.
