In order to assess the biocompatibility of domestic dynamic compression plates and screws manufactured at KAIST (Korea Advanced Institute of Science and Technclogy), hematological, serological, histological, and metallurgical studies were carried out on sixty rabbits through thirty-two weeks. The rabbits were divided into two groups, group I: thirty rabbits for KAIST plates and screws, group II: thirty rabbits for Osteo plates and screws. The plate and screws were fixed on the fixed tibial shaft. All the resulg of hematological, serological, histological, and metallurgical study revealed that there were no meaningful differences between the two groups. This, in fact, enco.urages us to use domestic KAIST plates and screws clinically and to develop more complicated designs including total joint replacement system.

BACKGROUND: Pruritus, which is a frequent accompanying symptom of dermatological diseases, is also common during pregnancy, either localized or generalized. It may be related to specific dermatoses of pregnancy. OBJECTIVE: A clinical study was performed to know the exact nature of pruritus in pregnancy. METHODS: Subjects with systemic diseases, or laboratory abnormalities were excluded. People who have had pruritic dermatologic diseases before pregnancy were also excluded. One hundred and fifty five pregnant women were interviewed with physical examinations and followed up to the date of delivery. Pruritus was graded. RESULTS: Pruritus was present in 31.6%. Most affected subjects had mild or moderate severity. The abdomen was the most common site. There was a tendency for the duration of itching to increase with the duration of pregnancy. CONCLUSION: Conclusion: These findings may provide basic and useful data on pruritus during pregnancy.

Fiber-reinforced composite(FRC) was developed as a structural component for dental appliances such as prosthodontic framework. FRC provides the potential for fabrication of a metal-free, excellent esthetic prostheses. It has demonstrated success as a result of its simple fabrication, natural colour, and marginal integrity, and fracture resistance of veneering composite resin and the FRC material. Although it has lots of merits, clinical and objective data are insufficient. The purpose of this study was to evaluate the fracture strength and marginal fitness of fiber-reinforced composite bridge in the posterior region for clinical application. Sixteen bridges of each group, Targis/Vectris(R), Sculpture-fibrekor(R)and In-Ceram, were fabricated. All specimens were cemented with Panavia 21 to the master dies. Strength evaluation was accomplished by a universal testing machine (Instron). The marginal fitness was measured by using the stereoscope (X50). The results were as follows. : 1.The fracture strength according to the materials was significantly decreaed in order In-Ceram(238.81+/-82). Targis Vectris(176.25+/-18.93), Sculpture-Fibrekor(120.35 +/-20.08) bridges. 2.FRC resin bridges were not completely fractured, while In-Ceram bridges were completely fractured in the pontic joint. 3.The marginal accuracy was significantly decreased in order Targis/Vectris (60.71micrometer), Sculpture-Fibrekor(73.10micrometer). In-Cream Bridge(83.81micrometer). 4.The fitness of occlusal sites had a lower value than the marginal sites(P<0.001), and the marginal gaps of inner site of the pontic were greater than that of outer sites of the pontic. Fiber reinforced composite bridges are new, esthetic prosthesis and can be clinically used in anterior regions and short span bridges. However, caution must be exercised when extrapolating laboratory data to the clinical situation because there are no long term clinical data regarding the overall success of the FRC.

Pterygium, a disease of unknown origin and pathogennesis, is a chronic condition characterized by the encroachment of triangular portion of the bulbar conjunctiva onto the cornea. We have studied the expression of extracellular matrix genes and oncogenes in cultured pterygium using Northernm dot, and slot blot hybridizations. Northern hybridization with total RNA isolated from passaged (4-8 passages) cultures demonstrated expression of genes for alpha1(I) and alpha1(III) procollagen, fibronectin, and c-Ha-ras, but no expression of gene for c-myc was observed. The pterygium exhibited significantly increased expression of alpha1(I) and alphal(III) procollagen genes when compared with normal control cells(p<0.01). And We observed there were no differences between pterygium and normal control cells in the expression of genes for fibronectin and c-Ha-ras. According to these results we thought that the causes of pterygium may be related to the increased expression of alpha1(I) and alphal(III) procollagen genes but may not be related to c-Ha-ras, c-myc, and fibronectin genes.

Two cases of clear cell syringoma are reported in the women who were 39 ad 54 years old, respectively. They had had asymptomatic, ricegrain-sized skin colored to yellowish pink papules on the face, particularly on he lower eyelid for several years. Interestingly, both of them had suffered from diabetes mellitus for more than a decade and been placed on irregular antidiabetic medications. Routine laboratory findings in the elder patient(case 2), unfortunately not checked in the younger patient(cases 1) due to her refusal, were within normal limits except marked glucosuria. Histologic examination revealed numerous various-sized, well-defined tumor nests composed largely of clear cells with polygonal cellular boundary and eccentric nucleus. Special stain with Periodic acid-Schiff disclosed existance of glycogen in the clear cells, but other special stains such as alcian blue showed negative findings. Electron microscopic examination of the elder patient revealed many multivesicular bodies suggestive of lysosomes, and numerous droplets of glycogen dispersed between them in villi-rich periluminal cell.

Addisons disease is the defieient production of glucocorticoid or mireralocorticoid or both, due to the destruction of the adrenal cor tex. We report a case of Addiaons disesse in a 26-year-old male who complained only of skin and oral mucosal hyperpigmentations without other constitutional symptorns, Physical examinations showed scanty pubic and axillary hsirs. On adrenocorticoid funtion study, the ACTH stimulstion test failed to rise the bassl plasme cortisol level and basal ACTH level was marked elevated st PM 6:00. Routine laboratory and other endocrinologic evaluations exhibited within normal limits. Radiologic findings showed negative on both cheet X-ray and abdominal MRI films. Gradisl disapperance of skin snd mucosal hyperpigmentation were noted following administration of phosiologic dose of corticosteriods. Almost normal appearance was obtaineg after 26 months treatment.

In general, the long head of the biceps brachii originates from the superior glenoid labrum and the supraglenoid tubercle, crosses the rotator cuff interval, and extends into the bicipital groove. However, rare anatomic variations of the origins of the long head have been reported in the past. In this report, we review the clinical history, radiologic findings, and arthroscopic identifications of 3 anatomic variants of the biceps tendon long head. As the detection of long head of biceps tendon pathology during preoperative radiologic assessment can be difficult without prior knowledge, surgeons should be aware of such possible anatomic variations.
