It is generally recognized that several chemical mediators are involved in tbe pathogenesis of sunbum; however, the exact mechanism is still to he resolved. Recently, prostaglandin has been found to be one of the inflammatory mediators in sunbum, particularly in the delayed erythema response and several investigators have shown that the nonsteroidal antiinflammatory drugs inhibit the in vivo synthesis of prostaglandin. On the assumption that the nonsteroidal antiinflammatory drugs might exert a beneficial effect on the sunbum through the antiprostaglandin effect, several authors have reported the effect of indomethacin on sunbum. This study was undertaken to evaluate the effect of topical indomethacin on the delayed erythema response induced by artificial sunlamp and sunlight by clinical and histopathological examination. Indomethacin(2. 5% ointment, 2. 5% solution, 5% solution) was applied immediately after 3 MED irradiation of artificial sunlamp to the shaved back skin of 6 healthy albino guinea pigs weighing 550-850gm and 9 human volunteers and the delayed erythema response was observed at 2, 4, 6, 12, 24 and 48 hours after irradiation respectively. Punch biopsies of the skin were performed on 6 guinea pigs at 6, 12, 24 a.nd 48 hours after irradiation and the histologic changes were observed. Four human volunters were exposed t,o 3 MED of sunlight and indomethacin preparations were applied immediately after irradiation. The delayed erythema response was observed at 2, 4, 6, 12, 24 and 48 hours postirradiation and in one volunteer, the skin was biopsied at 24 hour for histologi.c evaluation. The results were as follows: 1. Topical indomethacin in ointment or solution forms delayed and decreased the appearance and degree of erythema induced by sunlight and artificial sunlamp in both human and animal subjects. 2. Histologically, the number of sunbum cells at 24 hour in the epidermis of one human volunteer was decreased on indomethacin applied sites. The dermis showe6 no difference in histologic changes between control and indomethacin sitea. In animal study, however, no detectable difference in epidermal or dermal changes was observed between control and indomethacin applied sites. The autors confirmed that topical indometha,cin was effective in delaying and blanching of the delayed erythema of sunbum in guinea pigs as well as in human volunteers, though there was no difference in histologic changes between indomethacin and control sites in guinea pigs. The mechanism involvel on this aspect is remained to be resolved.

PURPOSE: The ictal perfusion patterns of cerebellum and basal ganglia have not been systematically investigated in patients with temporal lobe epilepsy (TLE). Their ictal perfusion patterns were analyzed in relation with temporal lobe and frontal lobe hyperperfusion during TLE seizures using SPECT subtraction. MATERIALS AND METHODS: Thirty-three TLE patients had interictal and ictal SPECT, video-EEG monitoring, SPGR MRI, and SPECT subtraction with MRI co-registration. RESULTS: The vermian cerebellar hyperperfusion (CH) was observed in 26 patients (78.8%) and hemispheric CH in 25 (75.8%). Compared to the side of epileptogenic temporal lobe, there were seven ipsilateral hemispheric CH (28.0%), fifteen contralateral hemispheric CH (60.0%) and three bilateral hemispheric CH (12.0%). CH was more frequently observed in patients with additional frontal hyperperfusion (14/15, 93.3%) than in patients without frontal hyperperfusion (11/18, 61.1%). The basal ganglia hyperperfusion (BGH) was seen in 11 of the 15 patients with frontotemporal hyperperfusion (73.3%) and 11 of the 18 with temporal hyperperfusion only (61.1%). In 17 patients with unilateral BGH, contralateral CH to the BGH was observed in 14 (82.5%) and ipsilateral CH to BGH in 2 (11.8%) and bilateral CH in 1 (5.9%). CONCLUSION: The cerebellar hyperperfusion and basal ganglia hyperperfusion during seizures of TLE can be contralateral, ipsilateral or bilateral to the seizure focus. The presence of additional frontal or basal ganglia hyperperfusion was more frequently associated with contralateral hemispheric CH to their sides. However, temporal lobe hyperperfusion appears to be related with both ipsilateral and contralateral hemispheric CH.

Normal lymphocyte transfer (NLT) test is composed of two peaks of delaycd. hypersensitivity reaction of erythema and/or induration developed at the site of intradermal inoculatioa of allogenic lymphocyte. It has been suggested that NLT test is a px.siblc homograft raaction, how var tlv exact mecha.nism is remained to be resolved. In leprosy, there has been accumulating evidenc. indicating defective cell mediated. immunity detected by varioua immunological tests. The present study was undertaken to evaluate the immune capability of patients with leprosy using NLT test. A total of 20 hea,lthy volunteers, 20 lepromatous and 22 tuberculoid leprosy patients who were under antileprosy chemotherapy with DDS for varying periods, entered this study. Lymphocytes from hepatitis associati antigen (HAA) negative donor were isolated with Ficoll- Hypaque density gradient method and the cell concentration was adjusted by normal saline so as to give 2, 5 million cells per 0. 1 ml. Each recipient was given 0. 1 ml lymphocyte suspension on the flexor surface of th right forearm intrad.ermally using 1 ml tuberculi n syringe with a 26 gauge needle. The appearance and the size of induration was checked daily for 2 weeks. In this atudy, the NLT reaction pattem was classified as follows: a. normal pattem showing the first peak and second peak of reaction. b. first peak only showing the first peak, but no second peak, of reaction. c. flat pattem showing neitger the first peak nor the second peak of reaction The results were as follows: 1. There were normal pattem in sixteen persons(80%) and first peak only in 4 persons(20%) among twenty healthy human volunteers. 2. There were normal pattem in four patients(20%), first peak only in six patients(30%) and flat pattem in ten patients(50%) among twenty letromatous leprosy patients. 3. There were normal pattem in twelve patients(54.5%), first peak only in eight patients(36.4%) and flat pattem in two patients(9.1%) among twenty-two tuberouloid leprosy patients. These findings suggest that NLT test may be useful in evaluating the immune capability in leprosy and host factor in belived to be important in the development of both first and second peaks of NLT test.

Benzoyl peroxide has been known to have bacteriostatic activity against Corynebacterium acnes and to have comedolytic action in patients with acne vulgaris. The present study was undertaken to evaluate the therapeutic effect of Renoxal, a 5% benzoyl peroxide lotion, in patients with acne vulgaris. A total of 35 patients entered this study at the Department of Dermatology, Seoul National University Hospital during the five months period from March to July, 1978. All patients were instructed to apply Benoxal on their affected sites once or twice daily; and the number of lesions on three fixed areas were counted before and every week for four weeks after the treatrnent. Two female patients stopped the application due to developrnent of contact dermatitis to Benoxal The results observed in the 33 patients were as follows: 1. The percentage decrease in total number of lesions in four weeks after treatment was 51.1% 2. Closed and open comedones were gradually eliminated; and their numbers were decreased in four weeks after treatment by 45. 8% and 55. 3% respectively. The papules were decreased. by 59. 1 @2 after the first week of treatment, but showed. a transient lag around tbe second week and then marked 61. 5% in four weeks after treatment. 3. Observed side effects included burning sensation,(3 cases), tightness (3 cases), itching sensation (2 cases) and scaling (1 case). All were tolerable without any specific measure or discontinuance of the application. The authors concluded througb this experiment that Benoxal (5% benzoyl peroxide lotion) is a very effective local therapeutic agent in the treatment of acne vulgaris patients.

We made a clinical study on 10 cases of histiocytosis syndrome who had been admitted to the pediatric department of Soon Chun Hyang University Hospital from Jan. 1982 to Dec. 1991. The results were obtained as follows 1) The sex incidence revealed male predominance with the ratio 4:1. 2) Among 10 cases, 4 cases were classified as eosinophilic granuloma, 1 case as Letterer-Siwe disease, 1 case as linfection associated hemophagocytic syndrome and 4 cases as malignant histiocytosis. 3) The mean age of symptom onset was 4 and 7/12 years in all disease group. 4) The common clinical symptoms and signs at dignosis were dyspnea, mass, pain on lower extremities and fever. 5) The most common organ involved among 9 organ systems was liver-spleen and the number of organ systems involved were 1 in 3 2 ases(30%), 3 in 2 cases(20%), 8 in 2 cases (20%) and 6, 7 and 10 organs in each 1 case. 6) The abnormal hematologic findings (Hb; 10g/dl and/or WBC; 4,000/mm3 and/or PLT; 100,000/mm3) were found in 6 cases. 7) Low serum albumin was found in 2 cases. Results of blood culture were Pseudomonas aeruginosae and Salmonella typhi in each 1 case. 8) The common findings on tissue biopsy were histiocytic proliferation and infiltration. 9) 4 patients of MH who recieved chemotherapy, a combination of adriamycin, vincristine, cyclophosphamide and prednisone were given in a total of four courses every 2 weeks ad induction therapy. When complete response was attained, a combination of adriamycin, vincristine, prednisone (AOP) and cyclophosphamide, vincristine, prednisone(COP) was administered alternately every 4 weeks as maintenance therapy for 6-64 months. 10) Among 4 patiens of MH who recieved chemotherapy, 1 patient was lost during induction chemotherapy, for 1 day.2 patients expired during induction chemotherapy, for 1 month, 1 patient expired during maintenance chemotherapty, for 8months, Eosinophilic granuloma cases (3) were recieved currettage and no recurrence. IAHS case due to typhoid fever was improved spontaneously.

Paneth cell-rich carcinoma is essentially an adenocarcinoma with a predominance of Paneth cells. A 60-year-old male patient was admitted with a history of abdominal distension for several months. Endoscopic examination revealed a large ulceroinfiltrative tumor involving most of the areas of the stomach. The biopsy of the lesion confirmed poorly differentiated adenocarcinoma and total gastrectomy was followed. The submitted total stomach contained a diffuse infiltrative Borrmann type IV mass with ulceration, 8.0 3.5 cm, at the body along the lesser curvature. Microscopically, it was composed of Paneth cell differentiated cancer cells and poorly differentiated tubular adenocarcinoma cells. The Paneth cell differentiation was characterized by cytoplasmic coarse eosinophilic granules, which were PAS-positive and positive reaction for lysozyme. Electron microscopic examination showed numerous, spherical, electron-dense, homogeneous granules corresponding to those in Paneth cells as well as mucin granules in the signet-ring cells, and various intermediate forms in some cancer cells, which might be immature in the Paneth cell lineage.

Solar urticaria is a rare skin disease characterized by urticarial reactions immediately following exposure to sunlight or artificial radiation. A 24-yr-old man had solar urticaria that was activated by visible light. Positive result of passive transfer of the reactivity with the patients serum to the skin of normal recipient suggested that his condition was attributable to an allergic response. Result of reverse passive transfer studies was negative. We report a case of solar urticaria which appeares to belong to type N in the classification of Harber.
