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.

A case of multiple myeloma associated with adenocarcinoma of the stomach was review. A 59-year, old Korean man had been abmitted to St. Mary's Hospital in January 1984, with chief complaint of posterior neck pain, and intermittent headache for one year prior to amission. Osteo lytic punched-out lesions were noted on skull and other skeletal x-ray films. Bone marrow aspirates revealed diffuse infiltration of mature and immature plasma cells. Laboratory findings revealed anemia and Bence-Jones proteinuria. Immunoelectrophoresis revealed findings consistent with IgA-lamda type multiple myloma. Alkylating agents and steroids were tried with some clinical improvements. In August 1985, the patient revisited outpatient clinic with chief complaints of epigastric pain and neck mass. Endoscopic biopsy and excision biopsy of the cervical lymph node were performed. By microscopic examination, adenocarcinoma of the stomach and metastasis of multiple myeoma to the supraclavicular lymph nodes were confirmed. Subtotal gastrectomy was performed. By gross and microscopic revealed metastasis to the regional lymph nodes.

A 31-year-old female patient has had a translucent cystic papule on the genitalia since 2 years ago. The diagnosis was confirmed by clinical and histopathological findings. This is the rare case of apocrine hidrocystoma occring in the fernale genitalia in the literature.

Tricilemmoma is a benign, solitary tumor that may be clinically misdiagnosed as basal cell carcinoma or verruca. It affects frequently the face of elderly rnen. We present herein a case of trichilemrnoma in a 70-year-old Korean wornan who had a slowly growing tumor on the scalp for 50 years. The histopathologic findings revealed lobular acanthosis of glycogeri rich clear cells and palisade of columnar cells resting on prominent basement membrane.

OBJECTIVES: The authors have intended to know the drug interaction of fluoxetine and haloperidol when coadministering two drugs to the chronic schizophrenics by assessing the changes of positive, negative symptoms and extrapyramidal symptoms. METHOD: We selected 38 patients, the chronic schizophrenics with no physical problems. they are randomly assigned to placebo group and drug group. And then, placebo or fluoxetine 20mg were administered to the subjects of each group during 8 week period. We have assessed their psychopathology and extrapyramidal symptoms using positive and Negative Syndrome Scale(PANSS), Clinical Global Impression(CGI), Simpson-Angus Scale at o, 2, 4, 6, 8 week during the period. RESULTS: 38 patients have completed the study during 8 week. 1) PANSS, CGI : no significant difference between groups and no significant change according to the times. 2) Simpson-Angus Scale : no significant changes. CONCLUSION: When co-administering fluoxetine and haloperidol, there were no significant changes of psychopathology and extrapyramidal symptoms. There results suggest that it is safe to coadminister fluoxetine to schizophrenic with haloperidol treatment.

The pretent study was performed to study the epiderrnal changes of ultraviolet irradiation and PUVA treatment in the black mice. The following results were obtained: 1) The histologic changes of the epidermis, number of DOPA positive melanocytes and ultrastructural changes of keratinocytes due to UVB and PUVA were rnore prominent than those of UVA irradiation. 2) The histological changes after 8-MOP photosensitization closely mirnic those of UVR irradiation, and constant, finding was hyperkeratosis. 3) Early histological change after UVL irradiation & IUVA treatment was appearance of dytkeratotic cells. 4) Pro]onged exposure to UVB & PUVA resulted in transient epidermal hyperplasia, and epidermal atrophy occurred 3 weeks after PUVA treatment. 5) Early electron microscopic changes was perinuclear edema, juxtanuclear vacuoles and clumping of tonofilament.

The use of interictal Tc-99m HMPAO SPECT images for localizing epileptic foci is limited by low sensitivty and specificity, while the routine use of ictal images is impractical for obvious reasons. To find out the possibility to solve these problems. We tried to stimulate the epileptic foci by provocation technique.
