Both irritation and staining reaction of anthralin on the skin are the two most important problem of therapy. Irritation, such as erythema, edema and staining by p. lg anthralin ointment were studied with the chamber-testing technique in 21 psoriatic patients. We campared the skin reaction of short exposure time, such as 1 hour, 2 hours, and 3 hours with those of exposure of 24 hours through 3 days after application. The results were as follows: l. Incidence of erytherna reaction was 81.9% in exposure of 1 hour, 85.7%, in 2 hours, 90.5%, in 3 hours and 100% in exposure of 24 hours. Degree of erythema reaction was increased according to duration of application. 2. There were no edematous reactions in exposure of 1 hour or 2 hours, 9,5% in 3 hours and 28,6% of grade 1 reaction in 24 hours. 3. There was no staining reaction in exposure of 1 hour, 48% in 2 hours, 9.5%, in 3 hours and 71.4% in 24 hours. Degree of staining reaction elicited by short exposure time were all weaker than reaction caused by 24 hours exposure.

The serologic testa for syphilis including VDRL and FTA-abs tests have been carried out in adult VISA applicants for emigration and bIood donors from February, 1977 to May, 1978. The results are summarized as followa: l. In 3,393 VISA applicants the reactive rate af VDRL test was 2.9%, and th biologic false positive rate of VDRL test was 5.1% using the FTA-abs test as the atandared. 2. VDRL test showed a positive rate of 2.3% in 6,220 blood donors. 3. The quantitative test of VDRL resulted in low titer belaw 1:4 in 93.9% of VDRL reactive VISA applicants. From the results it is clear that the prevalence of syphilis is grariually increasing recently compared to the late 1960s and early 1970s.

The present study was undertaken to inveatigate whether contaet sensitivity was decreased or not in patients with atopic dermatitis, and to investigate phagocytic function of neutrophils in patients with atopic dermatitis. 1. Dinitrochlorobenzene (DNCB), a compound which uniformly induce hypersensitivity in normal individuals, had been used in the preaent study to investigate cutaneous anergy in 16 patients with atopic dermatitis. Sensitizing does of DNCB (2,000 microgram) was applied and examined at 7th and 14th day for a spontaneous flare. In the absence of spontaneous flare, challenge dose (50microgram) was reapplied and examined. Seven of the 16 cases (43.8%.) had positive reaction to DNCB. These result showed decreased contact sensitivity in patients with atopic dermatitis, which suggested some defect in the cell-mediated immunity in patients with atopic dermatitis. 2. There were some evidence that susceptibility to certain infection was increased in patients with atopic dermatitis. For investigating killing function in phagoeytosis of neutrophils in patients with atopic dermatitis, nitroblue tetrazolium dye reduction (NBT) and stimalated NBT test had performed in 35 cases of atopic dermatitis and 20 cases of healthy control. 1) There was no significant difference in the mean percentage and absolute number of NBT positive neutrophils between whole group of atopic dermatitis (8. 4+4. 9%, 301.2+225.6) and control group (6. 9+2. 9%, 246.2+143. 8). 2) The mean percentage and absolute number of stmulated NBT poeitive neutrophils in whole group of atopic dermatitis (19.6+7.3%, 702. 1+377. 2) did not differ significantly from control group (22.7+5.3%, 812.2+382.2). 3) There was no significant difference in the mean value of NBT aad stimulated NBT test in comparing the mild groud, moderate group and severe group with control group. These resuIts suggested that killing function in phagocytosis of neutrophils in patients with atopic dermatitis was not impaired.

Three cases of pseudoxanthoma elasticum are presented and the literatures are reviewed. Two cases were presented with the marked cutaneous manifestation of this condition and angioid streak. One case was presented with only the marked skin lesion of this condition on both axilla and neck. Typically involved skin was shown to be speckled with pea-sized yellowish numorous papules. Typical elastic tissue degeneration was found in the involved skin. No genetic background was discovered in the patients.

This study was aimed to investigate the clinical manifestation of nail changes in psoriasis and was based on analysie of 205 p oriatics visited the department of dermatology, Seoul National University Hospital from November, 1984 to June, 1985. The results were summerized as follows: Nail changes were noted in 78(38. 0%) out of 205 patients in the finger nails. Toe nails were involved in 26(12 7%) cut of 205 patients. 2 Nail changes in male were noted in 49 (46, 7%) out of 105 patients and in female, 29(29%) out of 100 patients. 3. The peak incidence of nail changes according, to age group was over 40 years (45. 1%.) and the lowest incidence, under 9 years(26. 7%). 4, Pitting(57. 7%) was the commonest change ii the finger nails and subungal keratosis(50. 0%) and discoloration(46 2%) in the toe nails. 5 Incidence of nail changes according to psoriatic type was 23. 7% in guttate type, 42. 6% in nummular type, 53 3% in annular type. 6 The patients with the more severe degrees of psoriasis had a higher incidence of nail involvement. Mean duration of psoriatics with nail change and without nail change was 6. 3 years and 6. 5 years, respectively, 8 Among 65 patients with psoriatic nails, onychomycosis was noted in 9 patients(13.8%).

Anthralin is highly efficacious in the treatment of psoriasia, but it has two major drawbacks: staining of the skin and clothing and irritation of the skin. There have been several studies that the effect of the anthralin with short contact therapy(SCT) is nearly the same as that with the simple application(SA). This study was planned to compare the effect and side effects of SCT with those of SA of anthralin in 27 psoriatic patients visited between November 1982 and June 1983 at the Department of Dermatology, Seoul National University Hospital. The results could be summerized as follows: 1. For 4 weeks of treatment, the longer the duration of treatment, the more similar the effect between the SCT and the SA. 2. After 2 weeks of treatment, the effect of the SA was better than that of the SCT in 5 cases, the same in 18 cases and worse in 1 case. 3. For 4 weeks of treatment, all side effects(irritation, ataining and pruritus) were more frequent in the SA than in the SCT. And irritation was observed earlier than staining. 4. After 2 weeks of treatment, the side effects of the SA were more than those of the SCT in 12 cases and the same in 12 cases. With all our results, we have concluded that the patients who cannot tolerate the SA could be tried with the SCT.

We speculate that this is case of an intermediate state between granuloma annulare and actinic granuloma. This intermediate state would be a variant of granuloma annulare related to actinic damage. Therefore this case can be termed actinic granuloma annulare with generalized distribution.

The present study was undertaken to evaluate the efficacy of white petrolatum-UVB therapy on patients with psoriasis. Nineteen patients with chronic plaque type psoriasis selected in the Department of Dermatology, Seoul National University Hospital were treated with white petrolatum followed by exposure to UVB. Clinical response to therapy was graded as follows: Grade 1: Minimal improvement, Grade 2: Definite improvement Grade 3 Considerable improvement, Grade 4: Clearing. We campared the clinical response according to involved site: trunk and extremity. A responsive case was defined as a case with G4 in trunk and/or extremities. The results can be summarized as follows: 1. Fourteen of the 19 patients(73. 7%) were classified as being responsive cases. 2. Among the responsive cases, the 11 cases of trunk lesion all showed G4 clea- ring. The extremities lesion cases showed G4 clearing in 9 out of 14 cases, the other 5 cases showing GR. This showed that the trunk lesions were more responsive to the treatment than the extremities lesions. 3. In the cases of trunk lesions, the mean number of therapy was 6. 3 for G2 response, 11. 2 for GR and 16. 7 for GR. In the cases of extremities lesions, the mean number of the therapy was 8. 6 for G2, 16. 1 for GR and 19. 2 for Gl. 4. Pruritus was a complaint in 13 patients (68. 4%) during therapy. Among them moderate to severe pruritus was noticed in 6 cases (51. 6%). From the above results the emollient phototherapy seems to be an effective therapy in the treatment of psoriasis.
