Three cases of Dupuytrens contracture which developed in hands were reported along with review of literatures. Partial fasciectomy was done as the choice of treatment for them to improve impairment of function of the hands. No attributable causes for the developement of the disease were found.

Fluorouracil Was effective in controlling the in vitro cellular proliferation. When given with cultured human retinal pigment epithelial cell, fluoroirracil decreased the cellular activity of the cultured retinal pigment epithelial cell. The attachment and migratien of the cultured retinal pigment epithelial cell was markedly reduced after repeated treatment with fluorouracil. Electron micrographs of the cultured retinal pigment epithelial cell given with fluorouracil showed marked reduction of cytoplasmic pseudopodia, rupture of plasma membrane, loss of microorganelles and eventual cytolysis. Based on these data, low dose fluorouracil may be an effective inhibitor of the in vitro proliferation of the retinal pigment epithelium.

The linear scratching wound was made gently on the corneal epithelium of rabbit with 21 gauge needle under an operating microscope. Impression cytology was performed at 30 minutes, 1, 2, 3 and 4 hour and 1, 2, 3 and 4 day after 0.5% tetracaine drops under an operating microscope. The filter paper was stained with hematoxylin and eosin. At 30 minute post-scratching, a few polymorphonuclear leukocytes appeared on the scratched cornea at 3 eyes (30%). At 3 and 4 hour, numerous polymorphonuclear leukocytes with corneal epithelial cells appeared on the scratched conea. By 3 day, no inflammatory cells were shown on the filter paper in all eyes. These findings suggest that the polymorphonuclear leukocytes could infiltrate on the corneal lesion at 30 minute post-scratching and the inflammatory cells might act even on the minute corneal lesion such as corneal erosion.

PURPOSE: The purpose of this study was to analyze factors affecting burnout among clinical nurses according to Positive Psychological Capital. METHODS: The study design was a descriptive survey and questionnaires were collected from 412 clinical nurses who worked in a general hospital in "J" city. Data were analyzed using frequency, percentage, mean, standard deviation, independent t-test, One-way ANOVA, Scheffe test, Pearson Correlation, and hierarchical multiple regression. RESULTS: In Model individual characteristics accounted for 27.8% of the influence on burnout. In model II with the addition of the 4 factors; Self-efficacy, Hope, Resilience, Optimism, individual characteristics accounted for 48.5% of the influence on burnout. Optimism and Resilience of the Positive Psychological Capital sub-variables were statistically useful as factors influencing burnout. CONCLUSION: The results indicate that it is necessary to develop active human resource management and educational programs to decrease burnout and strengthen the Positive Psychological Capital of the nurses.

The 206 human embryonic and fetal eyes were conducted to investigate the structural change of the developing retina from Streeter age 13 to 40 week's gestational age with light microscopy. The development of the sensory retina was characterized by the appearance of the transient layer of Chievitz about 7 week's gestational age. The ora serrata was identified from the peripheral retina with the finding of the peripheral thinning around 13 week's gestational age. The transient layer of Chievitz was changed to a part of the inner plexiform layer around 15 week's gestational age. All retinal layers were apparent in structural characteristics around 19 week's gestational age and nearly complete in differentiation around 29 week's gest-ational age. During fetal stage, the retina was advanced in the region of the pos-terior pole than in the peripheral retina, the development of which was complete in differentiation about 36 week's gestational age.

The authors experienced a case of basosquamous cell carcinoma occuring in the eyelid, which was confirmed by the biopsy. Histological findings showed the infiltrating nests of malignant squamous cell with nests of basal cell infiltrating into the dermis. A huge ulcerating, infected lesion with irregular indurating border involved the entire lid and extended onto the orbital margin and nose with the nasolacrimal duct exposed. Because of the unusual case, it was felt that literatures review would be instructive.
