Oak moss is a lichen extract obtained from Evernia prunastri and Pseudovernia furfuracea. It is the potent,ial allergen in contact dermatitis to perfumes. Sensitivity to oak moss has been atributed mainly to atranorin, evernic acid, usnic acid and fumarprotocetraric acid. We report a 44-year-old female patient presenting with features of contact dermatitis due to oak moss in perfumes. Patch test results revealed positive reactions to fragrance mix, oak moss, atranorin and evernic acid.

We report a patient with a cutis laxa-like, generalized PXE without systemic involvement. A 28-year-old woman had loose, pendulous skin of the neck, axillae, thighs, trunk and body folds which resulted in a prematurely aged appearance. She had no family history of related diseases. Histological examination showed considerable accumulations of swollen and irregularly clumped fibers in the middle and lower dermis and von Kossa s stain revealed calcium deposits along the altered elastic fibers.

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.

This study aims to investigate the recent clinical and mycological trends of dermatophytoses in Pusan area. The number of patients with dermatophytoses diagnosed by KOH examination and culture at Maryknoll Hospital was 1, 213 during past 2 years from November 1982 to October 1984. The incidence rate of dermatopbytoses was 9. 8% out of 12,377 cases of out patients in total. Tinea pedis (33 .7%,) was the most frequent diagnosis, followed by tinea cruris, tinea unguium, tinea corporis, tinea faciale, tinea manus and tinea capitis, in the order of decreasing frequency. The majority of cases were found in the age group from 20 to 39 4, The over all ratio of male to female patients was ] 2: 1 5 The positive rate in KOH examination was 96. 2A, and it was especially low in the areas of scalp, face and toe webs. The positive culture rate was 55, 9g, and it was higher in the covered area than in the exposed area. 6 678 strains out of the 1, 213 patients were isolated and identified. The species isolated were, in the order of decreasing frequency, Trichophyton rubrum (558 strains, 82.3% of total organisms isolated), Tn'chophyton mentagrophytes (55,8, 1 Microsporum canis (48, 7. 1g) Epidermophyton floccosum (12, 1 8g) and Microsporum gypseum (5, 0. 7gp) Trichophyton rubrum was the major causative organism in all the types of dermatophytoses except tinea capitis and tinea faciale. In tinea capitis, Microsporum canis was the main causative organism, and Trichophyton ferrugineum was not isolated, at all, which was a specific point, compared with the past tendency. In tinea faciale, zoophilic organisms were mainly isolated.
