1.Change of Melanocytes in Fixed Drug Eruption.
Korean Journal of Dermatology 1989;27(2):171-176
Lesional and normal skins in 10 patients of fixed drug eruption were studied. Number and vertical distance of rete ridges were measured in H & E stained specimens. Amount of free melanin and number of melanocytes were counted in dopa stained epidermal sheets. According to the number of recurrence, activity and number of melanocytes see med to be changed. The lesions of a few recurrence showed only active melano cytes, however, those of frequent recurrenoe increased number of melanocytes with marked elongation of rete ridges. It is supposed that the numerical increase of melanocytes were from the elongation of rete redges.

2.Effect of suction blister fluid and IFN-gamma on HLA-A,B,C and HLA-DR espression in cultures human melanocytes.
Korean Journal of Dermatology 1991;29(2):151-154
HLA-A, B, C and HLA-DR are very important in the regulation of immune response and of transplant success or failure, but there have been a few reports about F3I A expression in melanocyt.es, a minor population of cpidermal cells. In the treatment of stable or segmental vitiligo, allogeneic melanocytes graft could t)e potentially useful if rejection does not. occur. The aim of this study was to examine the expression of HI.A-A, B, C and HI.A-DR in cultured hurnan melanocytes with and without. stimulation by INF-r and suction blister fliid. All strains of cultured me- lanocytes expressed HLA-A, B, C regardless of stmulation, but HLA-DR was expressed only following stimulation of INI-r. HLA expression in me]anocytes appears to be similar to that in keratinocytes.

4.Separation of Epidermis from Dermis with a Suction Device in Vitiligo Patients: Light and Electron Microscopic Studies.
Korean Journal of Dermatology 1989;27(5):488-494
Suction is a useful tool for separation of epidermis from dermis in vivo. With appropriate suction pressures and durations applied, cellular damage of the separated epidermis can reduce, This study was performed to examine the appropriste suction pressures and durations in the lhsional and normal skin of four vitiligo patients who wanted to take epidermal autograft. The suction pressures and durations for making the blisters of similar morphology were different according to person. Microscopic changes in the blisters of similar morphology were not very different, and suction of 200 to 250 mmHg for 2 to 3 hours with a 2cm diametered suction cup was considered to be acceptable. Obvious damage to keratinocytes and diminish of melanacyte number were observed with much more powerful and longer suction such as suction of 350 to 400 mmHg for 3 to 4 hours. The level of dermo-epidermal separation was between basal cell membrane.

Annals of Dermatology 1991;3(2):130-132
Sensitization to Cenasert®, a broad spectrum antimicrobial for the treatment of leukorrhea, is rare. Perineal contact dermatitis due to vaginal suppositories has never been reported in the medical literature. We report a 31-year-old woman, who developed perineal skin eruptions following the treatment of leukorrhea with Cenasert® vaginal suppositories. Patch tests showed positive reactions to Cenasert® suppositories and to the three active ingredients of Cenasert®. Vaginal suppositories can sensitize not only the vagina but also the surrounding perineum due to leakage of the allergen from the vaginal vault.

6.Neurilemmoma: A Dome-lesion on the Palm.
Korean Journal of Dermatology 1998;36(6):1101-1102
We report a solitary neurilemmoma on the left palm that occured in a 19-year-old man. The mass was a 1 * 1.2 * 0.7cm sized dome which was located between the thenar and hypothenar on the left palm. A biopsy specimen showed histological findings consistent with neurilemmoma:circumscribed nuclear palisading with Verocay bodies.

Korean Journal of Dermatology 1970;8(1):77-80
Two cases of pseudoxanthoma elasticum associated with angioid streaks in both eyes were presented and the literatures were reviewed. The affected sisters were 15 and 18 years female among the five siblings. They had pin head sized yellowish maculopapular eruptions on the sides of the neck and axillae, and also visual distubance of the both eyes. They seemed to be autosomal recessive inberitance in their family background. There were no other complications.

8.Vitrectomy in Complicated Pars Planitis.
Journal of the Korean Ophthalmological Society 1991;32(9):761-769
Consecutive twelve patients' twelve eyes with complicated pars planitis underwent pars plana vitrectomy at our center in the period from January 1988 to December 1990. Patients' ages ranged from 24 to 60(mean 39.9)years and all were male. Nine patients had histories of topical or systemic steroid therapy and at the time of surgery, all eyes were quiet from active inflammation. With various degrees of vitreal opacities, five eyes had macular pucker or membrane only and in other seven eyes, retinal detachments of either tractional or tractional-rhegmatogenous origin were arisen. In the later group, macular hole was associated in two eyes. Surgical procedures combined were membrane peeling(five eyes), scleral buckling(ten eyes), fluid/air-gas exchange(eight eyes), lensectomy(two eyes) and photocoagulation(two eyes). During the follow-up period ranged from four to twenty-one(mean 7.75)months after first operations, the uveitis recurred or continued to be activated in four eyes and as a complication, retinal detachment occurred in two eyes which had macular pucker only preoperatively. One refused reoperation and the other was reattached successfully by second operation. Final visual acuities were improved in eight eyes, stationary in one and worsen in three. The causes of worsen vision were retinal detachment, macular edema and macular slanting by buckle respectively. Preoperatively, the majority of eyes(10 eyes: 84%) had less than 0.09 vision and postoperative vision turned over better than 0.09 in 7 eyes(59%). Although we did not confirm extinguished therapeutic effects of vitrectomy on the pars planitis perse, our results revealed some positve role of surgical intervention in the complicated pars planitis.
