It is known that the toe-flexors exert some power generation in ankle plantar flexion. However, there has been no paper published in which the power generation was quantified. The purpose of this paper, therefore, is to quantify the amount of contribution of the toe-flexors to the ankle plantar-flexion in normal and rapid walking using the kinetic data of three dimensional gait analysis system. In order to restrict the action of the toe-flexors, we designed special braces which can be applied to the forefeet of the examinee during walking. We performed the gait analysis in ten normal adult volunteers with and without braces, and evaluated the moment and power of toe-flexors during terminal stance and pre-swing phase of gait cycle. Gait analysis was done with the VICON 3-dimensional motion analysis system (VICON, Oxford Metrics, Oxford, England) and 2 force plates (AMTI, Advanced Mechanical Technoiogy, Newton, MA, U.S.A,). The kinetic results are as follows: l. Average speeds of normal and rapid walking were 1.12m/sec and 1.41m/sec respectiveIy. 2. In normal walking, peak ankle plantar-tlexion moment decreased 5.5% with braces, and sum of ankle plantar-flexion moment decreased 12.3% with braces. Both of the results were not significant statistically (p>0.05). Peak ankle power generation decreased 11.0% with braces, and sum of ankle power generation decreased 10.4% with braces. These decreases were also insignificant statistically (p>0.05). 3. In rapid walking, peak ankle plantarflexion moment decreased 26.7% with braces. The decrease was horderline significant statistically (p=0.062). The sum of ankle plantar-tlexion moment decreased 26.6% with braces, but the decrease was not significant statistically (p>0.05). Peak ankle power generation decreased 40.2% with braces, and sum of ankle power generation decreased 37.9% with braces. These decreases showed borderline significance statistically (p=0.062). In conclusion, toe-flexors may contribute about 10% of the total ankle plantar-flexion power generation, and the contribution will be increased with increase of walking velocity. We must be very careful to sacrifice the toe-flexors in cases with weak triceps power.

A modern development of ambulatory ECG monitoring gave great advances in the diagnosis and evaluation of various cardiac conditions. Fifteen cases of ischemic heart disease, 11 cases of nonischemic heart disease, 5 cases of noncardiac disease and 9 cases of normal healthy subjects were studied from January 1980 to July 1981 in national Medical Center, with the following results: 1) The heart rate was decreased during night time, with less decreasing tendency in patients with ischemic heart disease. 2) Among 30 cases, including 12 patients with ischemic heart disease, who didn't show arrhythmia on routine 12 lead ECG, 12 cases, including 6 patients with ischemic heart disease, showed arrhythmia on Holter monitoring. 3) Among 5 cases with ischemic heart disease who showed premature ventricular contraction on day time monitoring, 2 cases didn't show premature ventricular contraction on nigh time monitoring. 4) The S-T segment and T wave were changed during night time in 2 cases with ischemic heart disease and in 2 normal subjects. From these results, we could assert that Holter monioring or ambulatory ECG tracing would be a good method for diagnosis and evaluation of ischemic heart disease, and other cardiac conditions. Several another studies with this equipment have to be performed and would give more distinctive outcomes.

As gastroduodenoscopy performed more frequently, case reports of human echinostomiasis are increasing in Korea. A Korean woman presented at a local clinic with complaints of abdominal pain and discomfort that had persisted for 2 weeks. Under gastroduodenoscopy, two motile flukes were found attached on the duodenal bulb, and retrieved with endoscopic forceps. She had history of eating raw frog meat. The two flukes were identified as Echinostoma hortense by egg morphology, 27 collar spines with 4 end-group spines, and surface ultrastructural characters. This report may prove frogs to be a source of human echinostome infections.

9.A Case of Congenital Long QT Syndrome with Reccurent Syncope.
Journal of the Korean Pediatric Society 2000;43(5):725-729
Congenital long QT syndrome (LQTS) is a disease characterized by prolongation of ventricle repolarization and by the occurrence, usually during emotional or physical stress, of life-threatening arrhythmias that lead to sudden death in most symptomatic and untreated patients. Two variants have been initially identified:the original Jervell and Lange-Nielsen syndrome of congenital deafness and autosomal recessive inheritance, and the more frequent Romano-Ward syndrome of autosomal dominant inheritance. Evidence also shows that approximately 25 to 30% of the cases are sporadic with syncope and a prolonged QT interval but without showing evidence for familial involvement. Familial and sporadic cases have been grouped under the definition of congenital long QT syndrome. We experienced a case of congenital long QT syndrome in a 13-year-old female girl. She had episodes of recurrent syncope and QT interval prolongation(QTc=0.46sec) in electrocardiogram(ECG). The ECG of her mother showed QT interval prologation(QTc=0.46sec). After applying atenolol, the QT interval returned to normal range and syncope has not occurred. We report a case of congenital long QT syndrome with a brief review of related literatures.

Diffuse leiomyomatosis of the esophagus is a rare condition and usually extends from the mid-esophagus to the proximal third of the stomach. Macroscopically, there is a marked diffuse thickening of the esophageal wall, with or without nodularity, predominantly affecting the circular muscle coat. Microscopically, the disorder is characterized by the loss of the normal orientation of the smooth muscle fibers of all three layers. We report a case in a 37-year-old woman which was incidentally discovered at exploratory thoracotomy.
