BACKGROUND: To evaluate the usefulness of exercise echocardiography in diagnosis of coronary artery disease and to compare it with exercise ECG test. METHOD: We performed exercise test in 48 patients who suffered from angina-like chest pain, according to the modified Bruce protocol. During exercise, we observed the ECG changes and recored the images of left ventricular wall motion before and after exercise on the video tape. The echocardiogram were digitally stored and displayed in a format that allowed simultaneous analysis of rest and stress images. Newly developed left ventricular wall motion abnormalities were determined as positive findings. RESULTS: The feasibility of exercise echocardiography was 75%. The sensitivity and specificity fo exercise ECG test was 67% and 89%. The sensitivity and specificity of exercise echocardiography was 85% and 100%. The sensitivity of ECG and echocardiography was 50%(7 of 14) and 78.6%(11 of 14) in those with one-vessle disease and 84.6%(11 of 13) and 92.3%(12 fo 13) in those with multi-vessle disease. CONCLUSION: Exercise stress echocardiography was very usefull method for detecting the coronary artery disease especially in single vessle disease. And it had much higher accuracy than the stress ECG test.

PURPOSE: To evaluate the functional outcome after surgical treatment for displaced fractures of proximal humerus and assess the final results according to surgical methods. MATERIALS AND METHODS: Thirty-three cases with follow-up over 12 months were divided into three groups: double tension band wiring (Group I, 14), plate fixation (Group II, 10) and closed reduction with internal/external fixation (Group III, 9). The pain index, the self-assessed functional score and the range of motion were obtained. RESULTS: Anatomical reduction was best obtained in group II and fractures united in 11-16 weeks. The pain index was worst in group III and the functional score of group I (80+/-12.2%) was higher than in the others (II: 69+/-15.7%, III: 55+/- 7.9%). The range of motion was worst in group III. Complications were noted in 9 cases, which occurred mostly in group II and III. CONCLUSIONS: Double tension band wiring in displaced proximal humerus fracture demonstrated that it provides a sufficient fixation for early rehabilitation and union, while minimizing complication

Since Pare's first report on Achilles tendon rupture in 1575, many authors have presented numerous operative and nonoperative methods for its treatment. Numerous controversies following its treatment have been concerned with the selection of its treatment method, which could minimizing the complications and enable early ambulation. We analysed 98 cases of Achilles tendon rupture in adults which were treated by direct repair, three-tissue bundle technique, or Plantaris/Peroneus augmentation repair for 3(1)/4 years from Oct. 1986 to Dec. 1989. We compared with types of cast after operation, periods for immobilization, and ankle motion of dorsiflexion at postoperative 6 weeks & long-term follow up. The results obtained from this study were as follows; l. After repair by three-tissue bundle technique, a short leg cast was applied, and then a weight bearing was started at postoperative 3 weeks. It can be demonstrated to shorten hospitalization and early ambulation when compared to other surgical techinques. 2. The patients who were repaired with the three-tissue bundle techinque averaged 12.5° dorsiflexion at the time of cast removal at postoperative 6 weeks, compared to 0°, 1° plantar flexion, and 4.4° plantar flexion with other techniques. The former group was significantly better than that of the latter group, and these differences were not present at long-term follow up. 3. On follow up period, discoverd complications were rerupture of Achilles tendon in 8 cases and mild wound infection in 3 cases, but the patients who were repaired by the three-tissne bundle technique showed no complications except mild wound infection in one case.

Five adult cases of post-laminectomy swan-neck deformity are reported. The factors causing the deformity, prophylactic measures, and treatment of the deformity are discussed. It is strongly adviced to the neurosurgeons and orthopedic surgeons that they should be aware of this unwanted complication of the multi-level cervical laminectomies, and that they should provide every preventive measures before post-laminectomy swan neck deformity develops. Anterior interbody fusion spanning the entire unstable segments is preferably recommended together with application of pre-fusion traction.

Isolated acute monoarticular septic arthritis of the sternoclavicular joint is a extremely rare disorder, and is usually associated with predisposing factors such as contiguous foci of infection, heroin addiction, rheumatoid arthritis, diabetes mellitus and maintenance hemodialysis. This case occurred in healthy adult. The etiological agent was staphylococcus aureus. Good result wads achieved by applying appropriate antibiotic therapy combined with an adequate drainage.

The damaging effect o flight on the eye has been recognized for centuries. Solar retinopathy is a well-recognized clinical entity of retinal damage caused by direct or indirect exposure to the sun. Symptoms of solar retinopathy include decreased vision, metamorphopsia, micropsia, and central or paracentral scotoma. Typical solar retinopathy presents clinically as a small yellowish-white foveolar lesion. The authors experienced a case of solar retinopathy which occurred in a 25-year-old female on both eyes upon gazing at the sun for 4 hours.

In present study, the mechanism for oxygen-glucose deprivation -induced [3H]gamma-aminobutyric acid (GABA) from cerebral cortex slices of the rat was examined. Deprivation of oxygen and glucose(OGD) from Mg2+-free artificial cerebrospinal fluid, induced significant release of [3H]GABA (7.4+/-0.6% of total tissue content) from cerebral cortex slices. OGD-induced release of [3H]GABA was significantly attenuated by tetrodotoxin(TTX)(1 micrometer), Mg2+(1.2 mM), MK-801(10 micrometer), ketamine(10 micrometer), N-methyl-D-aspartate(NMDA) receptor antagonists, (DNQX)(30 micrometer), and 6-cyano-7-nitroquinoxaline-2,3-dione(CNQX)(30 micrometer), kainate/AMPA receptor antagonists, or 6-nitro-7-sulphamoyl-benzo[f]quinoxaline-2, 3-dione(NBQX)(10 micrometer), a selective AMPA receptor blocker. OGD-evoked [3H]GABA release was attenuated by (NG-nitro-L-arginine methyl ester(L-NAME) and 7-nitronidazole, nitric oxide synthase inhibitors, and methylene blue, potentiated by zaprinast, a cGMP phosphodiesterase inhibitor. OGD-induced release of [3H]GABA was inhibited by nipecotic acid, a selective neuronal GABA transporter blocker, and potentiated by DL-2.4-diamino-n-butyric acid(DABA), a neuronal and glial GABA transporter blocker. Dantrolene (30 micrometer) and 1,2-bis (2-aminophenoxy)-ethane-N, N, N', N'-tetraacetic acid tetrakis (acetoxymethyl) ester(BAPTA-AM)(30 micrometer), inhibitors of intracellular Ca2+ release, verapamil(5 micrometer), omega-conotoxinGVIA(100 nM) and omega-agatoxinIVA(100 nM), inhibitors of voltage-dependent Ca2+ channels, significantly attenuated the OGD-induced release of [3H]GABA. These results suggest that glutamate is involved in OGD-evoked [3H]GABA release, and this release is achieved by Ca2+-dependent exocytosis and reversal of transporters, and can be modulated by various neuronal mechanisms.

Peripelvic lymphatic cyst or the kidney is a rare case in Korean Urological literature. We have experienced a case of it in 30 years old woman who had a palpable fluctuant mass in the upper right quadrant of the abdomen. The operated cyst was dark-red colored appearance and filled with amber colored fluid about 800cc. We have removed it together with kidney. The cyst measured 200gm. in weight, 10 x 5 x 4.5 cm in size and 0.5cm thickness of the cystic wall. Histological finding of the cystic wall showed a consisting of endometrial cell underlying tissue was collagen fiber and fibrotic change. The fluid of cyst contained 98 % of lymphatic cell.
