The routine closed patch tests were performe0 with 41 kinds of domestic soaps, detergents, cosm etics and topical medicaments (incIuding a adhesive plaster) on the intact skin of the back of 100 adult males without any dermatoses, to evaluate their side effects on the skin. 1, None of the materials showed no positive reaction, 2, The over all positive reactions were observed in 21.l% of my subjects, including a 1+reacti ons in,l6,4% and a 2+or 3, In 4.7% 3, In 12 kinds of soaps, Positive reaction wer observed in 19-33% positive of my subjects (average Z7.8%) 4, In 4 kinds of detergents, positive reations were observed in 6-19% of my subjects (average 9,7%), in which the highest reaction rate revealed was IVonderful of Dongsan fats and oils co.. 5. The positive reactiors in 3 kinds of toothpastes were observed in 37-61% of my subjects (average 50.7%). 6. The positive reactions to the adhesive plaster were observed in 25% of my subjects. Arnong 17 kinds of topial medicaments, positive reaction rates above 10 shown were Aroos oirtment of Sarn-A phaxmaceutical co. (49%), PM spirit of Kyungnam pharmaceutical co. (16%), Periio ointment of Namgang pharmaceutical co. (13%), Badional-Gel of Hanil pharm-aceutcal co. (10%) and Antiphlamine of Yuhan corporation (10%). 8. In 4 kinds of cosmetic creams, all showed higher positive reaction rates, i.e, "Masan Joongang cream of Yeinvonlang No I, 41%;No.2, 35%;N0.3, 32% and E.mong cream" of Daido phanna-ceutical co,44%.

Fifty-one cases of various warts were treated with 1-cbloro-2,4-dmitrobenzene (DNCB), and divided these warts into two groups by the method of treatment. The first group was treated by challenge on normal skin a,fter sensitization and the second group was treated by challenge on wart lesion after sensitization. The number of first group was 27 consisted of 13 of verruca vulgaris, 12 of verruca plana and 2 of condyloma acuminatum. The number of second group was 24 consisted of 10 of verruca vulgaris, 11 of verruca plana and R of verruca plantaris. The results are summarized as follows; 1. Thirty-one of all 51 cases (60. 7%) were cured. 2. Fifteen of 27 cases (55.5%) were cured in first group. 3. Sixteen of 24 cases (66. 6%) were cured in second group. 4. All 3 cases of verruca planaris were cured in second group. 5. Eight cases were cured only by sensitization and consisted of 6 of verruca plana and of verruca vulgaris. 6. There was no significant difference in cure rates of warts between the group within 2 years of duration and the group over 2 years of duration. 7. There were no severe adverse reactions.

This study was undertaken to investigate the response of non-immunologic contact urticaria(NICU) test before and after ingestion of cyclo-oxygenase inhibitors such as naproxene, ibuprofen and mefenamic acid. Forty patients who showed positive reaction to 5% benzoic acid (BA) in petrolatum by 20 minutes closed patch test were chosen and divided into 3 groups. Group I was consisted of 13 patients who were taken naproxene 250mg bid, group II, 14 patients, taken ibuprofen 600mg bid, and group III, 13 patients, taken mefenamic acid 500mg bid. All the patients were tested with 5%, 2.5%, 1%, 0.5% and 0.1% BA in petrolatum using Finn chamber on Scanpor tape on the right arm before medication and next day on the left arm after medication of each day. Mefenamic acid did not show any significant differences before and after ingestion of drug. Naproxene reduced reaction about half of patients. Ibuprofen reduced reaction in almost all patients and blocked reaction completely in 9 of 13 patients. This results suggested that there was no correlation between blocking effect to BA induced contact urticaria and so called anti-inflammatory potencies of naproxene and ibuprofen, and that NICU by BA is partly mediated by prostaglandins(PG) or mediated by other mediators, which were potentiated by PG, except histamin.

Suction is a useful tool for separation of epidermis from dermis in vivo. With appropriate suction pressures and durations applied, cellular damage of the separated epidermis can reduce, This study was performed to examine the appropriste suction pressures and durations in the lhsional and normal skin of four vitiligo patients who wanted to take epidermal autograft. The suction pressures and durations for making the blisters of similar morphology were different according to person. Microscopic changes in the blisters of similar morphology were not very different, and suction of 200 to 250 mmHg for 2 to 3 hours with a 2cm diametered suction cup was considered to be acceptable. Obvious damage to keratinocytes and diminish of melanacyte number were observed with much more powerful and longer suction such as suction of 350 to 400 mmHg for 3 to 4 hours. The level of dermo-epidermal separation was between basal cell membrane.

It is generally accepted that tbe lepromin test is of great value in the type classification and the evaluation of the prognosis of leprosy. But the nature of the antigenicity in lepromin reaction stiIl remains uncertain. The present study was carried out to investigate the antigenic characteriatics of the early(Fernandez) and the late (Mitsuda) reactions to Mitsuda lepromin antigen. Mycobacterium leprae was purified by trypsin digestion from human lepromas, and was broken down by passing 5 times through a French Pressor at 16, 000 p.s.i.. From the broken cell suspension, cell wall, cytoplasm, very low density lipoprotein (VLDL) and lipopolysaccharide (LPS) were prepared. IntradermaI skin tests were perforrned on 30 leprosy patients classified according to the Ridley-Jopling scale (4 TT, 6 BT, 2 BB, 7 BL and 11 LL), with 0. 1ml of the Mitsuda lepromin(intact cells) broken cells, cell wall, cytoplasm, VLDL and LPS antigens. Readings for the early and the late reactions were done 72 hours and 28 days, respectively, after itradermal injections of the above antigens. The results are summerized as follows: 1, Early reactions were elicited by broken cells, cell wall and cytoplasm in all of the patients who could react to Mitsuda lepromin antigen. VLDL and LPS antigens could also elicit early reactions in 9(56)% and in 14(88%), respectively, of the 10 patients who showed positive reaction to Mitsuda lepromin antigen. These results mean that the early reaction may be due to multiple antigena, originated either from M. leprae or from contaminated human tissues. 2. Late reactions were elicited by broken cells and cell wall antigens, but not by cytoplasm antigen, in all of the patients who showed late reactions to Mitsuda lepromin antigen. These results mean that broken cells also produce a late reaction and the specific antigen(s) of the late reaction may reside in the cell wall fraction of the M. leprae.

Erythema nodosum is clinical entity defined easily, but because of the variable histopathologic findings showing involvement of the vessels, septa, and fat lobules, the histopathologic features often are not compatible with the clinical diagnosis, We present the results of clinical and histopathologic findings in 26 patients with erythema nodosum observed at the Department of Dermatology, Seoul National University Hospital, fram January 1973 to August 1976. 1. Clinical Findings Erythema nodosum is characterized by painful erythematous nodose lesion occurring symmetrically(92%) on shins(50%) or shins and calves(50%) of women(M: F==4: 22) between sixteen to twenty five years old of age(58%) chiefly. In laboratory study, leukocytosis(1/17) was rare but increased titers of antistreptolysin(64%) and elevation of E.S.R.(88%) were found frequently. 2. Histopathologic Findings Even though hemorrhage(73%), perivascular(100%) and periadnexal(85%) inflammatory cell infiltration were frequently seen in histopathologic changes of erythema nodosum, these changes were nonspecific. Moreover, granulomatous change (38%), thrombophlehitis(35%) and necrosis of fatty tiasue(38%) were observed not infrequently in erythema nodosum. So we concluded that there were no specific histopathologic findings in erythema nodosum which differentiated from the other erythematous nodose diseases on the legs consisted of panniculitis, thrombophlebitis or granulomatous changes.

Lesional and normal skins in 10 patients of fixed drug eruption were studied. Number and vertical distance of rete ridges were measured in H & E stained specimens. Amount of free melanin and number of melanocytes were counted in dopa stained epidermal sheets. According to the number of recurrence, activity and number of melanocytes see med to be changed. The lesions of a few recurrence showed only active melano cytes, however, those of frequent recurrenoe increased number of melanocytes with marked elongation of rete ridges. It is supposed that the numerical increase of melanocytes were from the elongation of rete redges.
