The purpose of this study was to evaluate the characteristics of craniofacial skeleton on orthognathic surgical cases with skeletal Class III malocclusion. For this study, 74 students at the dental college of Chosun University volunteered as a normal occlusion group. They had well-balanced faces and good occlusions with acceptable Class I molar relationship. They had not received orthodontic treatment and had no signs or symptoms of temporomandibular joint dysfunction. 45 malocclusion patients enrolled for orthognathic surgical treatment with skeletal Class III malocclusion at the Department of Orthodontics, College of Dentistry, Chosun University. On the basis of this study, the results of this study were as follows: 1. Skeletal Class III malocclusion was largely due to the overgrowth of mandible in man and the undergrowth of maxilla in woman. 2. The mandible was antero-inferiorly overgrown by large MP-HP angle and large gonial angle in orthognathic surgical cases with skeletal Class Iii malocclusion. And also, upper incisors were severely labioversioned, but on the other hand lower incisors were linguoversioned. 3. In female, lower-third facial height was characteristically shortened in comparison with middle-third facial height and also, lower facial throat angle was sgrall in male.

Thelazia callipaeda, parasitic in the eye of 24 years old Korean male, was extracted from the left eye of the patient in Seoul, Korea. We confirmed that as T. callipeada morphologically, based on the descriptions of Hsu and other literature. We presents the 7th human thelaziasis case in Korea with the historical review of the literature.

PURPOSE: To determine the significance of anomalous position of the gallbladder. MATERIALS AND METHODS: Sixteen patients with anomalous position of the gallbladder were evaluated for analysis. The diagnosis was confirmed by ultrasonography(15 patients) and oral cholecystography(1patient). Among those, six patients underwent CT scan and a patient had 99mTc-DISIDA scan. The images were analysed with respect to the location of the GB and configuration and associated abnormality of the liver and hepatobiliary systems. Medical records of each patient were also reviewed. RESULTS: Among 16 patients having an anomalous position of the gallbladder, nine had retrodisplaced gallbladder, four had left-sided gallbaldder, two had suprahepatic gallbladder, and one had floating gallbladder. Except for one patient, fifteen had abnormality in the liver such as focal atrophic or hypoplastic change and liver cirrhosis. Intrahepatic stones were demonstrated in 6 patients. CONCLUSION: Our results showed that anomalous position of the gallbladder was commonly associated with atrophy or hypoplasia of the liver rather than congenital in origin. The possiblity of an anomalous location of gallbladder should be kept in mind when GB is not in its normal location.

This investigation evaluated the fracture toughness (KIC) of eight currently available core materials, and relate the fracture toughness value to fractography analysis and surface characteristics using a atomic force microscope (AFM). Single-edge notched (SEN) test specimens (n=10) and compact tension (CT) test specimens (n=10) were prepared conforming to the ASTM Standard E-399 for a high copper amalgam, three composite core materials (Core-Max II, Core Paste, Bisfil Core), two reinforced composite core materials (Ti-Core, Ti-Core Natural), a resin-modified glass ionomer core material (Vitremer), and a conventional glass ionomer core material (Ketac-Molar). The specimens were tested with an Instron Universal Testing Machine. The maximum loads were measured to calculate the fracture toughness (KIC). Thereafter, fracture surfaces of SEN specimens of each material were investigated for fractography analysis using scanning electron microscope. And, disc-shaped specimens with 1mm thickness were fabricated for each material and were investigated under AFM for surface morphology analysis. The results were as follows : 1. Bisfil Core showed the highest mean fracture toughness regardless of test methods. 2. For the tooth-colored materials, Ti-Core Natural exhibited the highest fracture toughness. 3. Ketac Molar showed a significantly low fracture toughness when compared with the amalgam and the composite resin core materials (p<0.05). 4. The fracture toughness values obtained with the single-edge notched test, except Ketac Molar, were higher than those obtained in the compact tension test. 5. SEM revealed that the fracture surface of high fracture toughness material was rougher than that of low fracture toughness material. 6. AFM revealed that the surface particles of the composite resins were smaller in size, with a lower surface roughness than the glass ionomer core materials.

We report the clinical features in one patients with episodic positional vertigo and apogeotropic direction changing horizontal positional nystagmus that does not fatigue, beating to the right with the head turned to the left and beating to the left with the head turned to the right. This syndrome probably represents a horizontal semicircular canal variant of benign positional vertigo. Free-floating debris and Cupula attached debris in one horizontal semicircular canal may explain many of the clinical and oculographic findings.

We report a patient with progressive supranuclear palsy (PSP) with his serial photographs before the onset of ocular symptoms and after the onset with two year intervals. These photographs show his progressive eyeball deviations toward complete exotropia. There were no effective voluntary eyeball movements, Bell's phenomenon, doll's eye movements, and vestibulo-ocular reflexes. These signs indicate the involvement of the oculomotor nuclear complex by the disease. We suggest that PSP may cause not only 'supranuclear' but also 'nuclear' complete ophthalmoplegia with exodeviation of the eyes.
