Atrophie blanche which was first described by Milian in 1929 is a sistinct entity and not a variation of stasis dermatitis. We reported a case of atrophie blanche which occurred in 21 year-old female. She had erythematous patches, telangiectaic purpuric areas, small 1 to 2mm ectasias suggestive of small angiomas with central ulcer, pustules and crusts on both lower legs and dorsa of feet without severe painful sensation. Histopathologic findings showed endothelial proliferation of the capillary blood vessele of dermis, presence of fibrinoid material on the superficial blood vessels and storma, and infarction of the epidermis and superficial corium. Response to treatment was not satisfactory with antibiotics and corticosteroid.

As an attempt to evaluate any possible effects of dimethylsulfoxide (DMSO) on the phenomena of membrane transport, effects on the short-circuit current (SCC) and potential difference (PD) across the isolated frog skin were studied under the conditions of various bathing medium, Changes of SCC and PD were measured by the method described by Ussing and Zerahn. Addition of DMSO to the inside bathing medium resulted in an initial increase in SCC followed by a secondary decline to pre-DMSO level, while DMSO at outside medium was without effect. Dose-responses(SCC) relationship revealed a linear one from 30 to 60 mM. Substitution of chloride by sulfate ion from bathing medium caused no alteration in the basic pattern and magnitude of response, thus indicating the specificity of DMSO action on the Na transport. Hypertonic solutions of DMSO added to either outer or inner bathing medium evoked a prompt fall in SCC and PD consistently. By isotopic measurement of sodium fluxes with Na24, it was evident that increased sodium influx was entirely responsible for the initial increase in SCC induced by DMSO. Of various parameters concerned with transepithelial Na transport, outer membrane permeability to Na (PoNa) was shown to be the onIy parameter which was significantly elevated by DMSO administration. From these findings, it was postulated that DMSO-induced increment in sodium influx was mediated by its stimulating action on the sodium penctration through the outer permeability barricr after binding to a receptor site different from that for the antidiuretic hormone (ADH.)

Clinicalstudies on thirty patients with lichen planus seen during the past 9 years from 1968 to 1976 at the Department of Dermatology, Busan National University Hospital were ma,de;particularly, varied clinical types of the disease and significance of histological findings were emphasized. The results obtained were as follows; 1. The incidence of lichen planus was 0.17% patients to total number of dermatologic 2. There were 19 males and 11 females in this series. The age at the first visit varied from 16 years to 71 years, and the pitients between 21 and 50 years occupied 76.7% of all. 3. The most common site of the initial lesion was extremities(66.7%), and flexor surface was rather common than extensor surface. And lesions of trunk, oral mucosa, extemal genitalia were also noticed. 4. The most common clinical type was chronic localized type(11), and hypertrophic type(4), Iichen planus of mucous membrane(4), annular type(4), acute widesprearead type(3), vesicobulIous type(2), linear type(2), follicular type(l) were also noticed. 5. Pruritus developed in 22 patints(73.3%) an@d Koebners phenomenon was noticed only in R cases(10%). 6. Histopathological examination of 25 biopsy specimens showed epidermal changes of hyperkeratosis(24), acanthosis(22), hypergranulosis(21), elongation of rete ridge(8) and liquefaction degeneration of hasal cells(25). Dermal changes include bandlike infiltration of infIammatory cells(24), melanophages in upper dermis(18), colloid or eosinophilic body(9), and dermo-epidermal separation(3).

BACKGROUND: Suction auto epidermal graft for the treatment of stable vitiligo has become popular clinically. In general, depigmented epidermis is removed by liquid nitrogen freezing for preparation of the recipient site. There have been some problems with the nitrogen freezing method, uneven repigmentation, appearance of Koebner's phenomenon on normal colored skin around the graft site, scar formation on recipients sites. In our view these resulted in unwanted damage to the dermis and epidermal and skin appendageal melanocytes of normal skin by freezing. OBJECTIVE: To introduce a method to remove the depigmented epidermis of recipient site with minimal unwanted damage to melanocytes and dermal tissue. METHODS: Using Ellman surgitron, irradiation equipment of 3.8MHz frequency the depigmented epidermis was removed with a blade electrode under rated electric power around 10 watts depending on the thickness of the epidermis. Operating mode was fully filtered current for minimal charring and destruction of tissue through pure micro-smooth cutting. RESULTS: In the case of removal of the epidermis with Ellman surgitron, oozing and inflammation decreased markedly compared with those applied with liquid nitrogen. And it was confirmed histopathologically that there was no significant unwanted destruction of healthy tissue. Moreover, the electrode of Ellman surgitron is designed to be apt to trace the margin of depigmented lesion. And Ellman surgitron features a continuously linear intensity setting for precise, predictable control to minimize tissue destruction and charring. So we were able to remove the epidermis of the shallow lesion looking like a pseudopod and of the thinnest part of the body like eyelid also. And we grafted normal epidermis successfully on the depigmented lesion. CONCLUSION: The removal of depigmented epidermis by radio-frequency gave satisfactory results in the suction auto epidermal graft by overcoming the defects shown as depigmented epidermis which were removed by liquid nitrogen freezing. And this method made patients comfortable because of less pain, a one day operation procedure and good results.

OBJECTIVE: To determine if stretching the sciatic nerve in control and patients with lumbosacral radiculopathy significantly alters F-wave parameters. METHOD: We studied F-waves in the deep peroneal & posterior tibial nerves of 20 patients with unilateral lumbosacral radiculopathies and 22 controls. F-waves were recorded bilaterally in the neutral position and supine in 30o & 60o straight leg raising (SLR). F-wave parameters included minimal latency (F min), maximal latency (F max), mean latency (F mean), latency difference between F min and F max (chronodispersion), mean duration (F dur) and side to side difference in F min, F max, F mean and F dur. RESULTS: In controls, the F-wave latency was found to be longer in supine with SLR than in neutral position. In patients with lumbosacral radiculopathy, significant differences of F max, F mean and F dur between sides during 30o SLR were noted in the deep peroneal nerves, but all parameters in the posterior tibial nerves during SLR were not changed. CONCLUSION: In this study, we observed significant changes in F-wave latency in control during straight leg raising, but no significant changes in patients with lumbosacral radiculopathy. For the clinical application to lumbosacral radiculopathy, further study is needed.

Spontaneous coronary artery dissection(SCD) is a rare entity that is infrequently diasnosed antemortem. The majority of patients have presented with acute myocardial infaction or sudden death. the etiology, prognosis and treatment of this entity remain ill-defined. We report two cases of SCD which were diagnosed by coronary agniogram and intracoronary ultrasound.
