Authors carried out experimental study on chemotherapy with oral administration of Dithiazanine iodide (D.I.) and Bithionol sulfoxide(B.S.) in rabbit clonorchiasis. And the following result was obtained. In change of the E.P.G (eggs per gram feces) by D.I. administration, it was rather increased in early stage of the administration than prior to administration, and thereafter decreased gradually. In the change of the C.S. worm body by D.I. administration, there was not only prominent change of supporting tissue but also the change of reproductive organ was found. In considering the wormicidal effect of D.I. from detecting rate of survival worms, the effect was slight in group of 100 mg(80 mg/kg) per day dosage, but the effects were very excellent and almost complete by proper times of administration in groups of 200 mg (130 mg/kg) per day or higher dosage. But the side effect and intoxication sign of D.I. were appearent in groups of 200 mg or higher dosage. By B.S. administration, E.P.G. was decreased gradually. In changes of the C.S. worm body by B.S. administration, prominent inhibitory chnnge was seen in egg formation ability. Slight wormicidal effect of B.S. was observed in groups of 140 mg (100 mg/kg) per day or higher dosage. Side effect and intoxication sign of B.S. were found little in groups of 140 mg or lesser dosage.

We present a case of acquired tracheoesophageal fistula (TEF) which was found during induction of general anesthesia for clipping of aneurysm. The patient had been intubated with endotracheal tube for 10 days and then done tracheotomy for 45 days. Thereafter, TEF was confirmed by MRI and treated with fistula repair and tracheal fenestration. Acquired TEF can occur under the condition of prolonged tracheal intubation with high cuff pressure (>30 mmHg) and can also result from intratracheal neoplasm, mediastinitis, and other tracheal or esophageal damages. If unrecognized during anesthetic induction, TEF can cause gastric dilatation and rupture, pulmonary aspiration and respiratory failure. So early diagnosis and proper management is very important whenever TEF is suspected during anesthetic induction.

The fractures of the both forearm bones are extremely common in children. Between the radius and ulna, there is normally through an arc of 180° rotation. To restore full rotation, rotational deformity and angulation after fracture must be corrected. The goal of treatment of the unstable forearm fracture is to increase the function of the forearm and hand as well as to get solid bone union. The general principle of treatment of forearm fracture in children is conservative due to remodeling and spontaneous correction ability. Thus, most fractures at any level need not and should not be treated by open reduction and internal fixation. But the operation will be perform frequently who shortly before maturity. We reviewed twenty-three children between 8-13 age, who had dsiplaced both forearm bones fracture, and who were treated with fixation using K-wire(14 cases) or plate(9 cases). Of the twenty-three fractures, sixteen were unsatisfactory reduction with more than 10° of angulation after initial closed reduction, two were loss of reduction in cast immobilization, and five were internally fixed primarily because of soft tissue interposition between fragment. The results were as follows. l. Operation time was 51.4 minutes in K-wire group and 86.7 minutes in plate group. 2. Bone union occured in all cases, at 7.3 weeks in K-wire fixation group and 8.9 weeks in plate fixation group. And immobilization period 7 weeks in K-wire fixation group and 4 weeks in plate fixation group. 3. Functional results were satisfactory all cases in both group. 4. The advantage of K-wire is a simple safe operation with minimal morbidity and small scar and compares with the extensive approach need for plate fixation which often giving a poor cosmetic result. Moreover, a second operation, with significant morbidity, is need to remove the plate after solid union. In Conclusion, this method is a favorable altenative to plate fixation of children forearm fractures. It allows rapid bone union with minimal morbidity, complication and scar.

With the advent of faster scan time and new computer program, a scanning technique called “dynamic computedtomography” has become possible. Dynamic CT consists of performing multiple rappid sequence scans after injectionof contrast material. The authors have evaluated the clinical usefulness of CT and dynamic CT of 93 patients withbrain infarction and/or ischemia during the period of 17 months from April 1983 to Aug. 1983 to Aug. 1984 inDepartment of Radiology, Chonbuk National University Hospital. The results were as follows; 1. The agedistribution ranged from 18 years to 78 years. Among them the most common age group was between 50 years and 59years(40.9%). 2. The sites of brain infarction were cerebral lobes(63 cases,68), basal ganglia(15 cases, 16.1%)and mlultiple sites(6 cases, 6.4%). The common affected site was middle cerebral artery territories. 3. Thecontrast enhancement of acute infarction was noted in 14 cases(17.5%) which occured commonly between 3 days and 2weeks from ictus. 4. The patterns of time-density curve in brain infarction and/or ischemia were as follow: a .Depression of slow wash-in phase was 20 cases(59%). b. Lower peak concentration was 17 cases(50%), c. Lower anddelayed peak concentration was 7 cases(21%), d. No definite peak concentration was 6 cases(18%). First threepatterns of time-density curve were thought as relatively characteristic curve of brain infarction and/orischemia. 5. Two cases that showed negative findings on precontrast CT scan appeared to be positive findings ashypodensity on postcontrast CT scan and were confirmed as brain infarction by dynamic CT. 6. The diagnostic entityof dynamic CT scan were as follows: a. large artery thrombotic infarction were 23 cases (58%). b. lacunarinfarction were 6 cases (15%). c. ischemia were 5 cases (13%), d. normal were 5 cases(13%), In six cases oflacunar infarction which was doubtful hypodensity on pre-and postcontrast CT scan had a marked difference in CT#(HU) on absolute scale graph of dynamic CT, so diagnosis of lacunar infarction could be made easily. 7. Theclinical values of dynamic CT consist in not only diagnosis of lacunar infarction but also evaluation ofeffectiveness of medical or surgical treatment.

Megaureter is a relatively rare disease and its first description was done by Caulk in 1923. It is characterized by marked ureteral dilatation without obvious cause, and occurs in lower ureter especially. Authers report a case of primary obstructive megarureter with CT demonstration in 19 year-old female. To our knowledage,this is the first case report of primary obstructive megaureter in Korea.

The size of spinal canal is valuable ot detect the body encroachment of spinal canal and expansion due totumors by computed tomography. This study was desinged for taking accurate measurement of the normal thoracicspinal canal in korean adults. The anteroposterior diameter, interpediculate distance and cross-sectional area ofthoracic spinal canal were measured in 80 normal adults. The results were as follows. 1. In A-P diameter, middleparts of the canal were smaller values than those of upper and lower parts from T1 to T6, and upper parts of thecanal were larger than those of middle and lower parts from T7 to T10. 2. In interpediculate distance, middleparts of the canal revealed larger value than those of upper parts. 3. All measurements of male were larger thanthose of female at all levels of the spinal canals and 65 measurement(93%) were statistically significant.

BACKGROUND: To avoid complications of homologous transfusion, many methods are used in patients who undergo an operation, but the autologous transfusion is most popular. This retrospective study was done to evaluate the applicability of an autologous transfusion in an orthopedic spinal surgery. METHODS: The cases of 239 autologous transfusion and 85 homologous transfusions in patients who had spinal surgery due to spinal stenosis were reviewed, and the differences in homologous transfusion, postoperative drainage and complications in both groups were compared. Both groups were analysed and compared by the T-test and Mann-Whitmann rank sum test. RESULTS: In the homologous transfusion group, 4.6 +/- 2.7 units of RBC products were used in 85 patients. In the autologous transfusion group more than 2 techniques of preoperative deposit, intraoperative autotansfusion by cell saver, acute normovolemic hemodilution, and postoperative autotransfusion were used, and 3.6 +/- 2.4 units of RBC products were infused to 49 out of 239 patients (P < 0.001). A postoperative hematoma occured in 2 patients after a homologous transfusion but there were no cases in autologous transfusions. CONCLUSION: Consequently much of the homologous transfusion could be saved by using an autologous transfusion, and smaller amounts of postoperative drainge occured, so the author could confirm the benefit of autologous transfusion.

BACKGROUND & OBJECTIVES: It was well known that benign paroxysmal positional vertigo(BPPV) was caused by the involvement of the posterior semicircular canal, but there were a few reports about horizontal canal variant of BPPV. We studied the clinical features electronystagmographic (ENG) findings and the possible mechanism of BPPV of the horizontal canal(HBPPV). METHODS: We examined 10 cases of HBPPV with episodic vertigo and intense horizontal geotropic nystagmus provoked by rotation of the head in a supine position. Six patients underwent ENG and we recorded four patients' nystagmus, provoked by rotating head from extreme lateral, mid and nose-up position to extreme contralateral direction in supine position. RESULTS: All observed horizontal nystagmus beated towards the ground on both sides and were more pronounced when head was rotated to pathological side. In rotating to pathological side, nystagmus had mean latency of 2.6+/-1.8 seconds, peak velocity of slow phase of 66,8+/-19.7 degree/second and mean duration of 24.7+/-3.4 seconds. In rotating to healthy side the nystagmus had 3. 7+/- 2.9, 38.0+/-11.5 and 22.5+/-4. Secondary phase nystagmus occurred in 2 patients and fatigue was observed in 4 patients. The slow phase velocity of nystagmus was relative to the distance of head rotation. The duration of attack is 3 to 17 days(6.9+/-5.2days). Liberatory manuever had relatively a good effect. CONCLUSION: HBPPV represents the origin of horizontal semicircular canal and has a good prognosis Above findings support that mechanism of horizontal BPPV is canalolithiasis.

Trichotillomania is a neuropsychiatric disorder characterized by repetitive pulling out of one's hair. We present a trichotillomania case study illustrating the effectiveness of habit reversal training, which has recently been found, in western countries, to be a very effective cognitive behavioral treatment. The refractory patient in our study had previously received 1 year of drug treatment and psychiatric consultation for the disorder. We administered 10 habit reversal training sessions, which was followed by an obvious improvement in the patient's trichotillomania symptoms. Our observations indicate that habit reversal training might be effective in the treatment of trichotillomania.
