The lower ureter is not so frequent site of the urinary tract obstruction. In lower ureteral obstruction, the obstruction should be relieved by any method for maintaining renal parenchyme. A clinical studies were made on the 24 ureters of the lower ureteral obstruction. This studies were mainly focused on the method of management by internal stent indwelling. The following results were obtained. 1. In etiology, acquired lower ureteral strictures were most common ; tuberculosis in 10 ureters, radiation in 6 ureters, pelvic lymphadenopathy in 4 ureters, and iatrogenic stricture in 3 ureters. Congenital UVJ stricture was only one ureter. 2. In the method of management, open surgeries were done in 10 ureters and endourologic methods in 14 ureters. 3. In 5 failures of the first management, open surgeries were done in 3 ureters and endourologic methods in 2ureters. The tuberculosis was the most of their etiology. 4. Complications in internal stent indwelled cases were flank pain, severe vesical irritation, migration into the bladder and the obstruction of the lumen of stent.

We compared the left ventricular ejection fraction by echocardiography with the ejection fraction determined by computerized radionuclide ventriculography in 59 patients who were admitted to the Soon Chun Hyang University Hospotal under the impression of cardiovascular disease from May 1984 to August 1985. The results were as follow : 1) In all patients the ejection fractions by both methods were significantly correlated with each other(r=0.77, P<0.001). 2) In 10 patients with ischemic heart disease the ejection fractions by both methods were not correlated significantly(r=0.42, P>0.10). 3) Except the 10 patients with ischemic heart disease, the ejection fractions by both methods were correlated significantly(r=0.87, P<0.001). 4) In conclusion, though the ejection fraction by the above 2 methods represent the left ventricular function well, the ejection fraction by echocardiography can not represent the left ventricular function precisely in patients in patients with ischemic heart disease because of abnormal left ventricular wall motion and left ventricular function more precisely than that by echocardiography.

The goals of treatment of the slipped capital femoral eiphysis(SCFE) are to stabilize the slipped epiphysis, prevent further slipping and induce early closure of the epiphyseal plate. Mutiple pinning was used for the treatment but in recent years, percutaneous in-situ fixation technique with 1 or 2 cannulated screws is preferred due to the advantages of low rate of complication such as pin penetration. We report the results of experimental study and the functional results after percutaneous pinning. The purpose of the experimental study was the investigation for changes of the screw length and the site of screw entry point according to the degree of slipping by bony model. The entry point of the screw was changed toward anterior and proximal portion of femoral neck and the length of inserting screw was changed to be shorter according to the degree of slip. We have treated 10 patients(13 hips) with slipped capital femoral epiphysis(SCFE) at our department since Jan. 1989. Among them, 6 patients(7 hips) could be followed for more than 2 years. There were 5 boys and 1 girl. One case was affected on the both hip. The average age at operation was 11.8 year old. All cases were obese. Degree of slipping was showed 6 cases in mild and 1 case in moderate. The slipping of acute onset was 3 cases, acute-on chronic 3 cases and chronic 1 case. In radiographic results, 6 cases were showing in Grade 0, 1 case was in Grade II. In functional results, 3 cases were excellent, 3 cases in good and 1 case in poor. One poor functional result was a case complicated by chondrolysis.

Fracture of the scaphoid constitute 60% to 70% of all diagnosed carpal injury. The acute fracture will heal approximately 90% of the time if recognized early and properly immobilized. But nonunion are common since the symtoms do not alert patients to seek early medical treatment and the diagnosis is easily missed. Authors have experienced 19 cases of scaphoid nonunion and accomplished good result in all case by Russe procedure. The results were summerized as follow: 1 The cause of fratures was mainly due to fall down dinjury (36.8%). 2. The most common mechanism of the fracture was fall on the outstretched hand (52.7%). 3. Fractures were shown on the anterior-posterior, lateral and billiards view in all cases. 4. In ten cases, the fractures were found on the waist of scaphoid. 5. The cases of nonunion were probably inadequate intial treatment and delayed diagnosis. 6. The good results were obtained by bone graft according to Russe procedure.

The herniation of intervertebral disc is possibly diagnosed through the myelography, electromyography, discography or computerized tomography. Among them, the myelography is regarded as the popularized method that helps accurate analysis on the location and pattern of the lesion. The authors have studied 363 cases of herniated intervertebral disc with respect to the diagnostic accuracy of myelographic examination from January, 1982 to December, 1985 at the Department of Orthopedic Surgery and Radiology, National Police Hospital. The results were as follows; 1. The most common age group was 21 to 30 years old and ratio of male and female was 9.7: l. 2. The most common site of the lesion was between L4 and L5 vertebra in myelography. 3. Of the 363 cases which underwent the myelography, 305(84.0%) represented positive findings. 4. Myelographic accuracy was coincided with the clinical diagnosis regarding the location of herniation of intervertebebral disc in 262 cases(72.1%).

OBJECTS: Sanjoin, the seeds of Zizyphus vulgaris var. spinosus has been used as the most important hypnotic agent in chinese medicine to treat insomnia. This research was performed in order to examine the effect of betulinic acid and sanjoinine-A which are components of Sanjoin. METHOD: Sleeping time, sleep recordings of EEG, serum serotonin level, and locomotor activity were measured in rats which received betulinic acid and sanjoinine-A as sleep induction material extracted from Sanjoin. RESULTS: 1) Groups received betulinic acid, sanjoinine-A, and lorazepam showed increased sleep time than control group with saline. 2) Groups with betulinic acid, sanjoinine-A, lorazepam and saline recorded beta-wave in sleep recording of EEG. In there was no significant difference among all groups. 3) No significant difference in serum serotonin level among all groups was found. 4) In autonomic activity testing, groups of betulinic acid, sanjoinine-A, and lorazepam showed significantly more decreased in activity than saline group. In comparison of groups of betulinic acid and sanjoinine-A with a group of lorazepam, there was no significant difference. CONCLUSION: These results suggests that betulinic acid and sanjoinine-A have the sedative effect like lorazepam rather than sleep effect.

BACKGROUND: Several reports have indicated that heparin has a bronchodilative effect in asthma patients, and that it enhances airway smooth muscle contraction in vitro, protamine is known to inhibit or enhance contraction of tracheal smooth muscle. Thus the effects of protamine and heparin on airway smooth muscle contraction are not consistent. However, no report is available on the effects of enflurane on heparin and protamine tracheal smooth muscle contraction. We performed this study to evaluate the effects of heparin or protamine on the carbachol induced contraction of tracheal smooth muscle in the guinea pig. And we also evaluated the effects of enflurane on heparin or protamine induced tracheal smooth muscle contraction. METHODS: Isolated tracheal rings of the guinea pig were suspended in Krebs solution. Contractions were recorded isometrically using a transducer. Contraction was induced by carbachol (10-6 M) and then cumulative dose responses of heparin or protamine (0.006 mg/ml, 0.02 mg/ml, 0.06 mg/ml, 0.2 mg/ml, 0.4 mg/ml) and in heparin (E) group and protmine (E) group, enflurane (4.34%) was administered for 15 minute after carbachol adminstration. RESULTS: Contraction by carbachol was inhibited by level of heparin or protamine at concentrations of 0.2 mg/ml and 0.4 mg/ml. At an enflurane (4.34%) contraction was inhibited, and no further inhibition of contraction by heparin or protamine was observed. CONCLUSIONS: Heparin or protamine inhibited the tracheal smooth muscle contraction induced by carbachol at 0.2 mg/ml and 0.4 mg/ml, and no further significant inhibition of contraction by heparin or protamine was observed after enflurane administration (4.34%).
