Among the complications associated with tissue expansion, bony depression under the expander is frequently observed clinically, especially under the tough skin like scalp. To investigate the bony change during the expansion and its reversability, we divided 21 young rabbits into 7 groups. After the insertion of tissue expander on the frontal bone, each groups are sacrificed at 1,2,3 weeks after tissue expansion, 1,2,3 months after removal of tissue expander, and for control, 4 weeks after insertion of expander without expansion. Bony changes are evaluated by gross findings, radiographic findings, and histologic findings. Progressive tissue expansion induces significant gross bony changes in skull of young rabbit. This bony changes consist of erosion underlying tissue expander, with bony ridging and bone deposition at the periphery of the expander. These gross findings correlates with the histomorphologic findings; osteoclastic bone resorption under the expanders with periosteal reation at the periphery of the expanders. The bony changes is not simply a pressure deformation, but also is a remodeling effect. Increased bone resorption and inhibition of bone formation occur until the pressure is removed. After removal of the expanders, reparative bone remodeling begins and nearly complete healing of the cranial defects occurs. On the basis of this study, we conclude that tissue expansion causes significant but reversible effects on cranial bone of young rabbit.

BACKGROUND: The photsensitizing effect of quinolones has been recognized since their introdulation as an antibacterial agents. Recently several new second eneration antibacterial agents of this pharmacological class have become available for therapy, and are gaining increasing impotance. OBJECTIVE: To reveal the phototoxic potentials of some new quinolones by photohemolysis test, estimation of fluorescenc spectra, and Candida albicans test. METHODS: Nalidixic acid and four second-generation quinolones(ciprofloxacin, enoxacini, norfloxacin, and ofloxacitid were examined by fluorescence spertra which measured t.he phototoxc potentials by photochemial instability, photohemolsis test for the phototoxic properties against cell membranes and Candida tlbicans test for phototoxic properties against DNA. RESULTS: All drugs showed a fluorescence spectra within 360 nm to 450 nm, and in the photohemolysis test, all studied drug except ofloxacin got above 5% hemolytic value, and all drugs showed clear zone. in Candida albicans test after 48hours. CONCLUSION: These results suggested that all tested drugs were photochemically unstable. According to the mechanisris of cellular phototoxicity, ciprofloxacin, enoxacin, and norfloxacin was phtototoxic to nucleus and cell membrane, whereas ofloxacin was phototoxic to nucleus only.

We report a case of multiple Bowen's disease associated with leprosy. A 68-year-old man was seen because of slightly pruritic multiple erythematous scaly patches and plaques on the trunk and the both extremities for 5 years. He has been treated for leprosy with many kinds of drugs consisting of the herb medications for over 40 years. He also showed decreased cell-mediated immunity in skin tests. It is considered that depressed cellular immunity may be an important predisposing factor in the development of mutiple Bowen's disease in this case, .although arsenics can not be completetly excluded.

A 31-year-old woman had a livedo reticularis of reticulated, bluish discoloration on both arms and legs for 18 months with a burning pain in the right hand and numbness in both lower legs. The findings of the electromyography were consistent with mononeuropathy multiplex and bilateral ulnar-median nerve anastomosis. A biopsy specimen from the right sural nerve showed perivascular lymphocytic infiltration and occasional myelin digestion chambers, which were consistent with vasculitic neuropathy. We present a patient with livedo reticularis idiopathica associated with mononeuropathy multiplex syndrome who also has bilateral ulnar-median nerve anastomosis.
