The purpose of this study was to investigate the causes of food impaction and to explore solutions as well. For this study, 39 patients with food impaction wee selected. 77 contact areas in these patients were investigated mobility, tightness of contact area, gingival index, plaque index, attachment loss, alveolar bone loss, proximal caries, marginal ridge distance and occlusal relationships. The results were as follows ; 1. Teeth without distal support were found to be the most frequent site of food impaction (41.6%). Food impaction was found to be more frequent in the upper teeth (66.2%) than the lower teeth (33.8%). 2. Food impaction was found in tight contact cases (71.4%). Alveolar bone loss was not found in the early stage of food impaction (83.1%) 3. The distance between the marginal ridges of food impaction sites (mean=0.48mm) was shorter than that of the control group. (mean=0.77mm) (p<0.001) 4. In 18.2% of t he cases, proximal carries were found at the food impaction site. 5. Food impaction affected patient's occlusion with the following frequencies ; cusp to marginal ridge relationship (72.7%), cusp to fossa relationship (3.9%) and stepped relationship (23.4%).

The aqueous bumor makes an important role to maintain intraocular pressure. The production and outflow of aqueous humor controls the intraocular pressure. The accurate understanding of the pathway of aqueous outflow and the rate of outflow is essential to the study of glaucoma. The purpose of this study is to investigate the pathway of aqueous outflow after injection of dye into the anterior chamber, the duration of staining and the degree of delay of aqueous outflow after the use of viscoelastics. Three dyes. Gentian Violet, Methylene Blue and Viscoelastics mixed with Gentian Violer were injected into the anterior chambers of 20 eyes of 10 rabbits. The eyes were enucleated at 1 hour, 2 hour, 3 hour, 4 hour after injection of Gentian Violer and Methylene Blue. After injiection of viscoelastics mixed with Gentian violet, the eyes were enucleated at 2 hour, 4 hour, 6 hour, 8 hour, and 9 hour. The enucleated eyes were performed for frozen section and the fragments were observed by light microscopee. Gentian violet and Merhylene Blue were stained in the pathway of the pectinate ligaments, trabecular meshwork, intrascleral plexus and the pathway of the capillary network of iris and suprachoroidal space. The disappearance of injected dye was ended between 3 hour and 4 hour. And the viscoelastics mixed with dye was removed between 8 hour and 9 hour. This means that viscoelastics make the outflow of aqueous delay.

Dysplasia epiphysialis punctata is a rare congenital disorder of infancy affecting in particular cartilage, muscle, jointtcapsules and the eyes. A case of dysplasia epiphysialis punctata with involvement of all epiphyses of extremities, spine and pelvis in 2 days old male is to be reported with review of literature.

Thirty-three cases of the fracture of the femur and tibia on the same limb were treated at the Orthopedic Department of the Chosun University Hospital during the period from January 1977 to December 1983. The following results were obtained. 1. The incidence of trauma was high in the young man, most frequent in the third decade (45.4%). 2. The most common cause of the fracture was traffic accident (81;8%). 3. The most common shape of the fracture was comminuted in both femur and tibia. 4. The common fracture site were middle one-third in both femur and tibia. 5. Eight patients were treated by conservative means on both femxr and tibia. The patients were treated by internal fixation on femur and by conservative means on tibia. Internal fixation was .done in ten patients on both femur and tibia. Two patients were treated by inteinal fixation on tibia and by conservative means on femur. Three patients were amputated. 6. Average healing time of fracture was 21 weeks in femur and 24.2 weeks in tibia. 7. Functional end results were assessed and rated with satisfactory results in rigid internal fixation of the femur and tibia.

Eight strains of multidrug-resistant (MDR) Salmonella typhi were isolated from Kyonggi area during January-February,1997. They were resistant to ampiciUin, amoxicillin, carbeniciillin, tetracycline, chloramphenicol, trimethoprim/sulfamethoxazole, trimethoprim. Eight strains had one plasmid respectively which size was approximately M.W 220 kb and showed same restriction pattern by endonuclease HindIII. The plasmid was similar to the plasmid in size that was related to multidrug resistant S. typhi isolated from southeast Asia. It were transferred by conjugation to recipient E, coli K-12 in frequency of 2.43 x10-4 - 1.73 x 10-2 and transconjugant showed same drug-resistant pattem with donor cells. All of 8 strains produced B-lactamase that was assummed to TEM-1 type by isoelectric focusing and PCR.
