The color change of maxillofacial silicone has been attributed to certain environmental factors such as exposure to the UV component of natural sunlight, wetting and drying of the elastomer, and surface abrasion resulting from the application and removal of cosmetics. The purpose of this study was to evaluate the color change of maxillofacial silicone (Silastic MDX4-4210) according to type of pigment (cadmium yellow, titanium white, cosmetic red), and UV absorber application method after 200, 400, and 600 hours of 350nm UV light irradiation. The results were as follows. 1. According to type of pigments, after 200 hours cosmetic red showed significantly larger color change than cadmium yellow and titanium white, and after 400 and 600 hours color change significantly decreased in the order of cosmetic red, cadmium yellow, and titanium white (p<0.05). 2. In the cadmium yellow group, after 200 hours, the non-treatment group showed significantly larger color change, but after 400 and 600hours, color change significantly decreased in the order of non-treatment, surface application and mixed group (p<0.05). 3. In the titanium white group, there was no significant color change difference between the three groups after 200 and 400 hours, but after 600 hours, the mixed group showed significantly smaller color change than the non-treatment and surface application groups (p<0.05). 4. In the cosmetic red group, there was significant decrease in color change in the order non-treatment, surface application and mixed group (p<0.05). From the results above, the effect of UV light absorber differed according to the type of pigment, but mixing UV light aborber with maxillofacial silicone is thought to give superior resistance against UV light irradiation in the long run.

Diaphyseal fractures of the radius and ulna present high incidence of malunion and non-union because of difficulty in reduction and maintenance of two mobile, parallel bones in the presence of the pronating and supinating muscles which exert angulatory as well as rotational forces. Over the years various methods of open reduction and internal fixation or the closed method have been advocated, but open reduction, especially fixation with compression plate and screws resulted in more satisfactory results was proved recently by the major clinical reports. From March. 1977 to December. 1985, 59 cases of diaphysesl fractures of the forearm both bone in adult and children were managed in the Department of Orthopedic Surgery, Chonbuk National University Hospital and comparisions have been made between the conservative treatment group and operative group. The obtained results were as follows; 1. The most common csuse of injury was fallen on the outstretched hand in children and traffic accident in adult. 2. The most frequent site of the fracture was middle one-third(50.8%). 3. The most common pattern of the fracture was stable fracture(50.1%). 4. The applied methods for management of the fractures include cast immobilization after manual reduction or skeletal traction, K-wire fixation, compression plate and screws, intramedullary nailing, and combined. 5. Comparision of conservative treated group with operative treated group was as follows. 1) In roentgenologically, excluding those complicated by nonunion or infection, average bone union time of conservative group in children and adolescence was 10.2 weeks and in adult was 16.7 weeks, and of operative group was 13.9 weeks. 2) According to Grace and Eversmann's evaluation, Satisfactory results were shown in 80.0% of children and adolescence group treated by conservative method and 86.7% of adult group trested by compression plate and screws. 3) Among the various internal fixstion methods, compression plate and screws method was the best measure for rapid bone union and functional recovery in adult. 4) Any marked difference between each group was not seen in nonunion, but angulstory and rotational deformity were more common in conservative group and infection was developed 2 cases in operative group only. 6. There was no noticesble difference between each treatment in children and adolescence, but operative treatment, especially compression plate and screws, in adult was more superior to conservative treatment with. regard to bone union time and functional result.

The intradermal (ID) test has been widely used in Korea and several reports about the results of the ID test are known. We examined the egg of Clonorchis sinensis (C.s.) by ID test in 443, stool's egg-counting technique in 79 and direct smear (cellophane thick smear technique) in 1204 subjects. The results are as follows: 1. The positive rate of C.s. was 3.8% out of 1304 persons. 2. The sensitivity of ID test was 82.1% out of 39 persons and the specificity was 64.6% out of 404 persons. 3. The false positive of ID test was 35.4% out of 404 persons and, the false negative was 17.9% out of 39 persons. Intradermal test is a rapid, sensitive and useful supplementary diagnostic tool for the detection of Clonorchiasis infection and must be used as screening test with direct smear of stool but cross reaction with other helminth infections and moderate false reaction are the main disadvantages in its practical application.

PURPOSE: This study presented the clinical outcomes at a minimum one year following anterior cruciate ligament (ACL) reconstruction using autogenous four-strand hamstring tendon and measured the strength of the knee flexor and extensor after tendon harvest. MATERIALS AND METHODS: Twenty seven patients who had a symptomatic ACL insufficiency underwent ACL reconstruction using four-strand hamstring autograft from Dec. 2003 to Jun. 2004. The patients were evaluated according to clinical findings (Lachman test, pivot shift test), standard knee scales (Lysholm, IKDC), and KT-1000 manual-maximal side-to-side difference. Functional test including one-leg hop test for distance and vertical jump test was performed and the strength of the knee flexor and extensor was measured using Cybex isokinetic test at last follow-up. RESULTS: At the time of follow-up, the average Lysholm score improved from 63.0 preoperatively to 95.0 and overall IKDC evaluation showed 14 patients was graded as A, 13 as B. There were 18 patients (66.6%) in negative Lachman test and also 25 patients (92.6%) in negative pivot shift test. The average KT-1000 manual-maximal side-to-side difference was 2.1+/-1.2 mm. One-leg hop distance and one-leg vertical jump test showed 12.3% and 22.3% decrement than uninvolved side. On isokinetic cybex test, peak extensor torque was 80.0% and 82.7% and peak flexor torque was 91.2% and 89.4% at the angular velocity of 60 degrees and 180 degrees/sec compared to the contralateral leg. CONCLUSION: ACL reconstruction using autogenous four-strands hamstring tendon seems to be a viable option for restoring stability with good clinical result and less donor site morbidity.

The effects of intravenous Verapamil administration on ventricular function were evaluated using grated radionuclide ventriculography in 15 patients with essential hypertension. Verapamil(0.1mg/kg) was injected as a bolus for 2 minutes followed by an infusion of 0.007mg/kg/min. Heart rate, blood pressure, ejection fraction, peak ejection rate, total filling time, and prak filling rate were assessed before and after Verapamil administration. The results were was as follows ; 1) Verapamil administration increased heart rate from 63+/-5 to 75+/-9 beats/min(p<0.01) and reduced systolic and diastolic blood pressure from 156+/-17/99+/-6mmHg to 139+/-16/88+/-6mmHg(p<0.01). 2) Ejection fraction, peak ejection rate, and total filling time were not changed significantly after Verapamil injection. 3) Right and left ventricular peak filling rate increased significantly only in patients in whom it was subnormal in the basal study) from 1.6+/-0.4 to 2.3+/-1.1 end-diastolic volumes/s, p<0.05 and from 2.5+/-0.6 to 3.1+/-0.8 end-diastolic volumes/s, p<0.05, respectively). In conclusion, it was found that intravenous Verapamil administration enhances ventricular diatolic function in patients with essential hypertension.

We report on three cases of subtrochanteric femoral fractures during trochanteric intramedullary nailing for the treatment of femoral shaft fractures. Trochanteric intramedullary nails, which have a proximal lateral bend, are specifically designed for trochanteric insertion. When combined with the modified insertion technique, trochanteric intramedullary nails reduce iatrogenic fracture comminution and varus malalignment. We herein describe technical aspects of trochanteric intramedullary nailing for femoral shaft fractures to improve its application and prevent implant-derived complications.

An unusual case of glroependymal cyst involving the lateral ventricle, 3rd ventricle, cerebellopontine angle cistern and prepontine cistern, simultaneously, is reported. The glroependymal cyst is benign developmental cyst that mainly occurs in the cerebrospinal axis in relation to ventricle, but occasionally occurs in relation to extraventricular system, such as subarachnoid space, brain stem and cerebral parenchyme. The histological characteristics of ependymal cyst wall are ependyma-like epithelium and neuroglial tissue.
