Balloon pulnounary valvuloplasty is an established method in the treatment of congenital valvular pulmonary stenosis. Balloon valvuloplasty was performed by using one or two balloons in a total of 19 mongrel dogs. Cross sectional area ratio ranging 145-406% was used to compare the relative sizes of the pulmonary annulus the balloon Hemodynamic changes and cardiac damages in single and double balloon groups were analyzed. Survival time of double balloon group was longer than that of single balloon group(P<0.05). Increment of the right ven?dular systolic pressure in single balloon group (mean 38 mmHg) was greater than that in double balloon group (mean 18 mmHg) (p<0.05). Decrement of the femoral arterial pressure in single balloon group (mean 87 mmHg) was greater than in double balloon group (mean 41 mmHg) (p<0.05). The locations of trauma were mainly the right ventricular free wall, the main pulmonary artery, the anterior leaflet of the pulmonary valve and in a less degree, anterior wall of the right atrium, the right ventricular outflow tract and the left pulmonary artery in the order of frequency. There were no significant differences in cardiac damages between single and double balloon groups (P>0.05). Major microscopic findings were sloughing of the endotheliu, fibrin deposition, hemorrhage, localized myocardial infarction and so on. In conclusion, double balloon pulmonary valvuloplasty is superior to single balloon technique in survival time and hemodynamics. Therefore, double, balloon technique is recommended for the pulmonary valvuloplasty.

Twenty-seven consecutive patients who had post-traumatic stiffness of the elbow were treated by operative soft tissue release or by soft tissue release and distraction arthroplasty. The purpose of this study was to describe the method of operation and postoperative management and to evaluate the results in the patients who had operative treatment for the post-traumatic stiffness of the elbow. The type of operative procedure was determined by whether the factors limiting motion were extra-articular (extrinsic) or intra-articular (intrinsic) and by pre-operative radiographic evaluation. The soft tissue release was performed by staged adhesiolysis through lateral or combined lateral and medial approaches. And if the factors limiting motion included a severe intraarticular lesions, distraction arthroplasty using the Judet or Oganesian apparatus was added to soft tissue release. The mean pre-operative arc of active motion was 42 degrees. At follow-up examination, nineteen to sixty-six months postoperatively, the mean post-operative arc of active motion was 103 degrees. There were nine complications (33 percent) in twenty-seven patients. All of them was transient ulnar nerve paresthesia. And we analysed the final results with Mayo elbow performance index for the evaluation of clinical outcome. Twenty-five (93%) of twenty-seven patients had satisfactory result according to Mayo elbow performance index. We conclude arthrolysis with or without distraction arthroplasty is useful for the treatment of posttraumatic elbow stiffness. However, the accurate anatomical knowledge, operative skill, and careful postoperative rehabilitation program were needed in the operative treatment of post-traumatic elbow stiffness.

BACKGROUND: Not rarely we can find young people with acute myocardial infarction(AMI), many studies revealed they have fewer risk factors and less severe coronary angiographic abnormalities than middle and old aged group. METHODS: We studied clinical characteristics and coronary angiographic findings of 5 young men with AMI treated at Masan Koryo General Hospital from June 1986 June 1992. RESULTS: The age ranged between 19 and 32 years(mean 25.4). They had no other risk factors except cigrarette smoking(4 out of 5). Their coronary angiograms revealed no significant lesion in each infarct related artery. After discharge, all patient remained asymptomatic. CONCLUSION: AMI in young man might be related with cigarette smoking, and coronary artery spasm and/or thrombosis may play a significant role in its pathogenesis.

Authors observed the 242 patients who were treated with hyperbaric oxygenation therapy from September, 1972 to May, 1978 at our department of B.N.U.H. The results were as follows. 1) Sex distribution was 106 male and 136 female, and the age group was between 10 and 39 year old, which occupied 71. l% of the total cases (172 cases). 2) With regard to distribution by month, 206 cases were in November to April, using coal briquette as the main fuel of heating systems. 3) The patients with CO intoxication were 232 cases(95. 9%) and the other 10 cases included Buergers disease, gas gangrene, sudden deafness and uncommon dermatologic disorder's such as scleroderma and pyoderma gangrenosum. 4) 188 cases(77. 7%) were treated by one time hyperbaric oxygenation therapy and 30 cases(12. 4%) twice, reflecting that most cases were able to be treated only once or twice by hyperbaric oxygenation therapy. Therapy 10 to 49 times was applied to Buerger's disease and sudden deafness, and over 50 times to 2 cases of dermatologic disorders. 5) We could not notice convulsion due to oxygen toxicity, a complication of hyperbaric oxygenation, but tinnitus and aspiration pneumonia were observed in 6 cases(2. 5%).

PURPOSE: Platelet Rich Plasma(PRP) application is increasing with sinus inlay bone graft, but there is few research with radiographic ananlysis on effect of PRP in maxillary sinus. The author investigated the amount of bony changes of maxillary sinus for dental implantation among the patients with maxillary inlay graft. MATERIALS AND METHODS: With 10 patients who were treated with sinus inlay autologous bone grafting combined with PRP technique, and with 5 patients who were treated with sinus inlay grafting only without PRP, the panoramic radiographys which were taken at preoperation, immediate postoperation, 3months postoperation, and 4 months postoperation(a month after dental implantation)periods were analysed. The films had been scanned, and then proceeded throughout image analysis system. The bone density of maxillary grafted sites was compared with adjacent tooth enamel density and remeasured according to density luminosity of each film. The density changes on PRP group and bone graft only group were an lysed with non-parameteric statistics method. RESULTS: In PRP combined patients group, bone density on postoperation periods was increased totally. The remarkable enhanced change of bone density was observed on 3 months postoperation period, thereafter the increasing rate was slightly reduced . In only bone graft patients group, bone density on postoperation periods was also increased compared with preoperation period, but the bone density of 4 months postoperation period was decreased compared with 3 months postoperation period. The amount of bone density on PRP group was significantly changed according to periods in contrast to bone graft only group. CONCLUSION: The bone density on PRP group was remarkably increased at 3 months postoperation compared to bone graft only group and it was seemed to be associated with more new bone formation, less grafted bone resorption at bone grafted sites with PRP.

The Parasitological investigation on the encysted metacercariae in brackish water fish, Tribolodon taczanowskii Steindachner , in the downstream of Hyungsan river which is located in Kyungpook province of Korea, were carried out, and the following results were obtained. Metacercariae of Metagonimus species were found in seventy five fishes (40.5 percent) out of 185 examined. Parasitic frequencies of the encysted matacercaria of Metagonimus species in Tribolodon taczanowskii were 23.2 percent (43 out of 185) in the scale, 7.0 percent (13 out of 185) in the gill, and 10.3 percent (19 out of 185) in the flesh. The number of the metacercaria in the scale, gill and flesh were fewer than that of the others. The worms were identified as Metagonimus yokogawai Katsurada, 1912 by morphological studies on the adults and eggs, and compared with prereported Metagonimus species.

BACKGROUND: Tourniquet pain is probably mediated by C-fiber. The ability of fentanyl to interrupt this nociceptive conduction was studied by administering either fentanyl or saline intrathecally along with hyperbaric bupivacaine for spinal anesthesia. METHOD: The incidence of tourniquet pain was evaluated in 60 patients having orthopedic surgery of the lower extremities during spinal anesthesia by administering either 30 mcg fentanyl (group 2) or saline (group 1) along with 0.5% hyperbaric bupivacaine 10 mg. We measured the maximal sensory spread of analgesia to pinprick, the incidence of tourniquet pain, and the sensory anesthesia to pinprick at the onset of tourniquet pain. RESULTS: The average maximal sensory spread of analgesia was the same in both groups (T9). The incidence of tourniquet pain was significantly greater in group 1 (33%) than in group 2 (10%). The sensory levels of anesthesia at the onset of tourniquet pain were not different in two groups. CONCLUSIONS: Intrathecal fentanyl was effective against tourniquet pain for 2 hours of the orthopedic surgery of the lower extremities.
