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.

Arthroscopy became a popular techique for the diagnosis and treatment of wrist disorder. But the specific indications for the wrist arthroscopy are not well defined. So we reviewed our experience of 16 wrist arthroscopies of radiocarpal and midcarpal joints. With this review, arthroscopy was of benifit in the diagnosis and treatment of the lesion of the triangular fibrocartilage complex and also in the synovectomy.

We present herein a case of pyodcrma gangrenosum, who showed good response to clofazimine therapy. The patient, 19-year-old male, had suffered from chronic diarrhea for 10 months before the rapidly spreading pustules and ulcers with undermined purple-to-red borders devkloped on his both lower and upper extremitics. Clofazimine was given orally in a dose of 100mg three times daily for 16 days, and tapered to 100 mg two times daily for the next 11 days. Clinical improvement was noted after 7 day's treatment and the almost all of the skin lesiors were replaced by granulation tissue with epithelizatiori or crust formation after 6 days treatment.

We present herein two cases of acquired periungual fibrokeratoma occuring beneath the proximal nail folds. A firm duplicated and mitten-shaped protruding mass was found on the left middle finger nail of 38-year-old woman and a firm triplicated and finger-shaped protruding mass was found of the left great toe nail of 46-year-old man. The epidermis of the tumors showed compact hyperkeratosis, focal hypergranulosis, and irregular acanthosis. Thick collagen bundles and dilated capillaries were predominantly oriented in the direction of the longitudinal axis of the lesions. There were no adnexal elements and inflammatory cells in the dermis.

We present herein a case of 20 nail onychogryphosis with localized plantar hyper keratosis and cutaneous horns occuring in a 21 year-old schizophrenic female patient. The finger nails were brownish in color and the surface of nail plates has the coarse transverse striations. The nail plates beyond the free edge were thickened and curved inward markedly. The toe nails were dirty grayish in color and the nail plates were thickened markedly and curved like the horn of ram. All the nail plates were seperated and removed from the nail beds without any difficulty and the nail matrices were destroyed by electrodesiccation. Lacalized plantar hyperkeratosis and cutaneous horns were also removed successfully by occlusive dressing with 40% salicylic acid ointment and by surgical excision. Psychogenic disorder and prolonged hygienic indifference could be the most. probable cause in this patient.

We report a case of chronic bullous dermatosis of childhood occurring in a 8-year-old girl, who has multiple, pruritic, tense, vesicobullous eruptions on the both extremities and pelvic region without mucous membrane inuolvement. A skin biopsy revealed subepidermal vesicles infiltrated with many neutrophiles and a few eosinophiles. Direct immunofluorescent study of the perilesional skin demonstrated moderate intensity of linear IgA and to a lesser degree of IgG deposition at the dermoepidermal junction. The skin lesions responded dramatically to oral dapsone therapy, initially 4mg/kg, and taporing to 2mg/kg for 27 days.

Primary role of ultrasound in patients with thyroid nodule is to determine the multiplicity and detect occult carcinoma. We analyzed US findings of 53 thyroid carcinomas with multiple nodular lesions from january 1988 to december 1991. The results were as follows: 1. 109 malignant nodules in 53 cases and 24 benign in 23 were comfirmed. 2. The nature of the masses were solid in 72 malignant nodules (74.2%), and complex in 25 (25.8%) of which 19 were predominantly solid. 3. The echo pattern of the solid and solid predominant masses were hypoechoic in 78 malignant nodules (80.4%), hyperechoic in 10 (10.3%), and isoechoic in 3 (9.3%) 4. Internal punctate calcifications within the masses were observed in 31 malignant nodules (31.9%). 5. Halo sign was present in 16 malignant nodules(16.5%). 6. The preoperative sonographic diagnosis of thyroid carcinoma was made in 39.4% of 53 cases with multiple nodules on US. In conclusion, the number, and halo formation of nodules were insignificant to differentiate the benign nodule from the malignant. The heterogeneous hypoechoic nodules with size greater than 4cm, multiple stippled calcifications, displacement of the trachea or other surrounding structures of combined lymph node enlargements seem to indicate the possibility of malignancy.
