BACKGROUND: Chronic exposure to ultraviolet radiation(UVE) nduces photoaging characterized by dry, deeply wrinkled, inelastic, leathery, and irregulaity pigmented skin. UVR also induces solar keratosis and carcinoma, and is a contributing factor in melanoma. Sunscreens are used to prevent solar damage to skin and, if used on a daily lass should significantly reduce the incidence of the chronie photodamaging events. OBJECTIVE: We tried to evaulate the photoaging effects of UVR in the skin and the photoprotective effect of sunscreens. METHOD: We examined the gross and microscopic changes skin of albino hairless Skh : HR-1 mice exposed chronically to ultraviolet B(UVB) and suncreen-treated mice. RESULTS: The skin of the UVB-irradiated mouse shows chear, cteristic signs of photoaging, such as deep wrinkles across the back, and thickened and a hery skin. Histologically, the photoaged skin shows increased epidermal thickness, numeross fibroblasts and inflammatory cell infiltration in the upper dermis, and many enlarged keratering cysts in the lower dermis. By the 20th week, seven of the total of 9 mice(78%) in UVB irradiated mice developed at least one tumor. Histologically, the tumor is a papilloma, but the he are many dyskeratotic cells and loss of polarity in epidermis. Octyl methoxycinnamate or TiO ZnO Talc-treated mic show a significantly decreased wrinkling score, mimmal epidermal hyperplasia, slightly increased dermal cellularity, and lack of proliferation of cysts. The octyl dimethyl PABA-treatd mice shows significantly increased wrinkling score and marked inflammatory infiltration dermis. By the 20th week, only one mouse had developed a tumor in the octyl methoxy irmamate-treated group and no evidence of tumor was seen in the TiO ZnO Talc-treated group. In the octyl dimethyl PABA-treated group, five of 7 mice(71%) developed at least one tumor. CONCLUSION: The skin which is chronically exposed to UVB is subject to photoaging and photocarcinogenesis and regular use of an adequate sunscreen would prevent these photodamaging effects of UVB.

PURPOSE: This study tried to explore factors influencing on job maintenance of the mentally disabled who employed before. The subjects of this study were the mentally disabled who participated in community mental health center and social rehabilitation center, there had experienced a job in the past. METHODS: The number of community centers were 27 places, there were located in different region. The number of participants were 221 persons agreed to this study. Data was analyzed by Mean, SD and logistic regression analyzation using SPSS/WIN 14.0. RESULTS: General character such as age was significant factor. Monthly pay and working a day in the midst of job related factors were significant. Moreover, job rehabilitation program satisfaction rate and social support revealed significant factors. CONCLUSION: On the basis of results, Job rehabilitation programs for job maintenance of the mentally disabled should be development and establish mediate strategies to improve social support to them.

Common peroneal nerve injury has been reported as the most frequent lower extremity peripheral nerve injury. The peroneal nerve may be particulary prone to direct or indirect injury by penetrating trauma or external compression by it's superficial route to bony prominence of fibular neck. By the development of microsurgical technique, recently epineural repair, fascicular group repair, and interfascicular graft were tried. The authors have experienced five cases microsurgical repair of common peroneal nerve injury around the knee joint from December 1990 to November 1991, and motor and sensory result was relatively good.

The term pseudolymphoma is not specific, and a variety of infl; m atory reactions may simulate clinically and histopat,hologically a cutaneous malignant lymphomas udolymphoma induced by drug therapies, especially anticonvulsants, have been reportecl. These pseidayrnphornas most commonly appear as single lesions. Characteristically, few localized lesions disappear after discontinuing therapy with the offending drug. Multiple and generalized tumors are very rate. We report a case of generalized cutaneous pseudolymphoma assocated with phenytoin therapy in a 52-year old male patient.

BACKGROUND: Stellate ganglion block (SGB) is known to increase blood flow to the innervations area of the stellate ganglion. Near infrared spectroscopy reflects an increased blood volume and allows continuous, non-invasive, and bedside monitoring of regional cerebral oxygen saturation (rSO2). We investigated the influence of SGB on bilateral cerebral oxygenation using a near infrared spectroscopy. METHODS: SGB was performed on 30 patients with 1% lidocaine 10 ml using a paratracheal technique at the C6 level and confirmed by the presence of Horner's syndrome. The blood pressure (BP), heart rate (HR) and rSO2 were measured before SGB and 5, 10, 15 and 20 minutes after SGB. Tympanic temperature of each ear was measured prior to SGB and 20 minutes after SGB. RESULTS: The increments of the rSO2 on the block side from the baseline were statistically significant at 5, 10, 15 and 20 minutes. The rSO2 on the non-block side compared with the baseline, however, decreased at 15 and 20 minutes. The difference between the block and the non-block sides was significant at 15 and 20 minutes. The BP at 10, 15 and 20 minutes was increased and the HR was increased at 10 and 15 minutes. CONCLUSIONS: We observed an increment of the rSO2 on the block side from the baseline; however, the rSO2 on the non-block side decreased.

OBJECTIVE: We previously described that Diva is highly expressed in matured metaphase II (MII) oocytes compared to immature germinal vesicle (GV) oocytes in mouse.1 We report here that the expression of Diva transcript as well as protein is oocyte-specific. To elucidate its physiological role in oocyte, the binding partner(s) of Diva has been identified by using immunoprecipitation (IP) followed by Mass Spectrometry. METHODS: NIH/3T3 cells were transiently transfected for 24 h with either empty vector for control or FLAG-tagged mouse Diva construct, and IP was performed with anti-FLAG antibody. The immuno-isolated complexes were resolved by SDS-PAGE on a 12% gel followed by Coomassie Blue staining. For in-gel digestion, 15 bands of interest were excised manually and digested with trypsin. All mass spectra were acquired at a positive reflector mode by a 4700 Proteomics Analyzer (Applied Biosystems, Framingham, MA). Proteins were identified by searching the NCBI nonredundant database using MASCOT Peptide Mass Fingerprint software (Matrixscience, London). RESULTS: Diva-associated complexes were formed in FLAG-tagged mouse Diva-overexpressed NIH/3T3 cells via IP using anti-FLAG-conjugated beads. Among the excised 15 bands, actin and actin-binding proteins such as tropomyosin, tropomodulin 3, and alpha-actinin were identified. Binding between Diva and actin or tropomyosin was confirmed by IP followed by Western blot analysis. Both bindings were also detected endogenously in mouse ovaries, indicating that Diva works with actin and tropomyosin. CONCLUSIONS: This is the first report that immuno-isolated Diva-associated complexes are related to actin filament of the cytoskeletal system. When we consider the association of Diva with actin and tropomyosin, oocyte-specific Diva may play a role in modulating the cytoskeletal system during oocyte maturation.

Hydroa vacciniforme is a very rare photosensitivity disorder. The primary skin lesion is a vesicle or bulla which then heals with vacciniform scarring. We report a case of hydroa vacciniforme recurred after 3 years period of quiescence in a 20 year-old man who had had history of the disease from the age of two. The duplication of the natural lesion, clinically and histologically, was successfully made by artificial UV-A irradiation on the patient's back.

Granulocytic sarcoma.(chloroma) is a localized tumor mass composed of immature cells of the granulocytic series infiltrating an extramedullary site. The tumor may involve anywhere in the body, especially orbit, bone, epidural space and lymph node, but there is no case involved the esophagus. In a 34-year-old male presented with sudden anset of dysphagia, esophagoscopic examination revealed concentric narrowing of the esophageal lumen wirith alight granular mucosa in the midesophagus, which hiatologically proved to b a granulocytic sarcoma. Peripheral blood and bone marrow aspiration smears showed blastic crisis of chronic myelocytic leukemia. After the systemic chemotherapy, dysphagia and mid-esophageal luminal narrowing disappeared completely.

A case of pulmonary alveolar proteinosis is reported. Most of the alveolar spaces were filled with amorphous deep eosinohilic material which revealed strong positive reaction to periodic acid-Schiff staining. Electron microscopic observation of this material showed numerous lamellar bodies in the alveolar spaces and cytoplasms of alveolar macrophages. A part of them were concentric multilamellated type A lamellar bodies and the other were finger printlike type B bodies. Combined type A and type B lamellar bodies were rarely present. From the above features it is suggested that both type A and B lamellar bodies could be transformed one another and those lamellar bodies may be originated from pulmonary surfactant.
