Tolerance to contact hypersensitivity was induced by feeding of different DNCB doses in mice. A total of 40 mice were divided into 4 groups(control group, 6 mg feeding group, 10 mg feeding group, 14 mg feeding group) in experiment I, Degree of tolerance to contact hypersensitivity was rneasured by incremert rate of ear swelling after challenge with DNFB. Experiment 2 was performed in the same method of cxperiment: I with addition of 3 mg DNCB feeding group. The increment ratee were significantly decreased in DNCB feeding groups in experirnent 1 and 2(p<0.0l). But there were no differences statisticalIy between increment rates of DNCB feeding groups.

Increased melanin pigmentation following ultraviolet irradiat.ion is due to increasing tyrosinase activity and multiplicatian of functioning melanocytes. After UV-irradiation, the size of melanocytes increases, and melanocyte dendrites elongatc, and branch. In this experiment, we induced the activation of melanocyts in the epidermis of C57BL black mice by ultraviolet-B(UVB) irradiation and observcd ihe effect of azelaic acid and retinoic acid on the UVB activated epidermal melanocytes. Sixty C57BL black mice were irradiated by UVB 100mJ/cm daily for 10 days, and then azeiaic acid and retinoic acid were topically applied daily for 7 weeks. For the estimation of morphologic change of epidermal melanocytes, light microscopic observation with split DOPA stain was performed at the end of the 1st, 3rd, 5th and 7th week of topical application. The results are summerized as follows : 1. The number, size and circumference of DOPA-positive epidermal melanocytes were significantly decreased in 20% azelaic acid applied group and 30% azelaic acid and 0.05% retinoic acid applied group. 2. In 20% azelaic;i.cid and 0.05% retinoic acid applied group, the number, size and circumference of DOPA-positive epidermal melanocytes were nore significantly decreased than in 20% azelaic acid applied group. In summary, the present study suggets that azelaic acid act as a depigmenting agent on epidermal melanocyte; and such depigmenting effect of azelaic acid was increased by addition of retinoic acid.

Corneal ulcerations are divided into two morphologic types: central and marginal. Marginal corneal ulcerations are characterized by focal, muItifocal, multifocal or diffuse ulcerative, infiltrative, or vascular involvement of the peripheral cornea, and the exact pathogenesis of these ulcerations is not clearly understood but infectious, toxic or autoimmune factors may be involved. The authors treated one peripheral corneal ulcer patient, no respond to steroid and antibiotic therapy, with lamellar keratoplasty and had a good result.

A 24-year Korean woman presented with bizarre pigmentary skin changes. Eruptive vellus hair cysts (EVHC) were observed in conjunction with Hypomelanosis of Ito (HI). Also, the karyotype of 45XO with typical clinical symptoms of Turner's syndrome was detected in this patient, which has been rarely reported in HI as a chromosomal defect. EVHC may manifest as a rare skin manifestation of Hl.

BACKGROUND: The cornified cell envelope (CE) is a unique structure found in the terminal differentiation of the skin. The precursor proteins of the CE are composed of many candidate structural proteins, among which invalucrin and filaggrin are important ones to participate in the complicated process of forming, the complex structure. OBJECTIVE: The purpose of this study was to evaluate the usefulness of expression of involucrin and filaggrin as markers of terminal differentiation in various skin disorders including tumors. METHODS: Immunohistochemical studies were performed in the formalin-fixed, paraffin-embedded skin samples of non-tumors (41 cases) and tumors (43 cases).

A 23-year-old woman with Down syndrome presented erythematous keratotic plaques with whitish scales on the elbows, forearm, knee and leg. Histopathological findings revealed acanthosis with broad and short rete ridges, alternating orthokeratosis and parakeratosis oriented in both vertical and horizontal directions, and dermal superficial perivascular lymphocytic infiltration, compatible with pityriasis rubra pilaris.

BACKGROUND: Ciclopirox 8% nail lacquer is a new topical antifungal agent which is character ized by excellent penetration into the nail plate to the infected koratin and remains there for a prolonged period. We per formed a st,udy to assess the therapeutic efficacy and safety of ciclopirox 8% nail lacquer in the treatment of onychomycoses. METHODS: We used 20 satients with onychomycoses, which was confirmed by KOH ancl fungus culture. The ciclopirox nail lacquer was applied once daily for 1 month, and followed by two times weekly for the next 5 months. The clinical observat.ion was perforrned every month for any clinical improvement and side-dffects. The involved percent of a target nail was measured by using a adhesive tape at.ached to the selected nail plate. All involved nails(n=68) were also evaluated by a severity score(sever>50%. moderate 25-50%, mild<25%). RESULTS: Seventeen patients were finally assessed because of the deletion of 3 patients througl loss of contact. The involved percent of target nail was significantly decreased from 57.4% at baseline to 27.9% througli the 6 month-treatment(p<0.01, ANOVA). The total reduced precent of target nail involvement at the end of the treatment was 52+22% on average. The precent of severly involved nail(>50%) in all 68 involved nails was also decreased from 56% at baseline to 7% by the end of the treatment The mycologieal cure rate was 82.4% by the end of the treatment. The overall efficaor assessed by the physician and patients was improvement by 82.4% Tolerability was excellent or good in all patients, but cosmetic acceptance was good or excellen by 53%. Only one patient complained of a prickling sensation, but no systemic adverse effect were found. CONCLUSION: These data suggest that ciclopirox 8% nail lacquer may be safe and effective ir the treatment of onychomvcoses.
