Roots of manually extracted scalp hairs among 86 healthy Koreans in different age groups were examined microscopically and the proportion of resting hairs to growing hairs were determined with the fol[owing results. 1. The proportion of resting hairs in all age groups was 10. 9% and there was no significant difference between male and female. 2. In each age group the proportion of resting hairs show's difference, being lowest (6. 8%) in below 9 years age group, increasing the rate by increasing the age group, highest (19. 7%) in over 60 years age group. 3. The proportion of resting hairs below the age of 29 years was below 10%, above 30 years to 49 years in between 10% to 15% and over 50 years in between 15% to 20%. 4. The normal range of the proportion of resting hairs among normal Koreans was below 20%.

The present study was performed to evaluate clinical manifestations in 26 patients and histopathological findings in 19 patients with Behcets syndrome. 1. Clinical findings: A. Among the 26 patients, 9 were male and 17 were female (male to female ratio was 1: l.9). The age at onset of the disease varied from 10 to 62, with a mean of 26.9. B. The incidence of the major clinical manifestations: The oral ulcers were observed in all of the 26 patients, genital ulcers in 21 patients (81%), cutaneous manifestations in 25 patients (96%) and ocular lesions in 7 patients (27%). C. Saline intradermal test was positive in 62% and PPD intradermal test in 42% 2. Histopathological findings: Fourty-one specimens were taken frorn 19 patients with Behcets syndrome; Erythema nodosum like lesions (15), edematous papules (3), acneiform eruption (1), oral ulcers (4), genital ulcers (8), saline intradermal injection sites (5) and PPD intradermal test sites (5). As a control, 4 specirnens were taken from PPD test sites of the patients with erythem nodosum. The common histopathological findings were perivascular inflammatory cell infiltration, mainly composed of neutrophils and nuclear dusts, and vasculitis of varying degree. A. Cutaneous lesions; In erythema nodosum-like lesions main pathologic foci were in the deep dermis and/or the subcutis, and moderate to severe vasculitis were observed. In edematous papules, however, main foci were in the pa,pill- ary dermis and the upper dermis, papillary dermal edema was prorninent, and vasculitis was rather mild.

Subepiderral calcified nodules is a special form of idiopathic calcinosis circumscripta with its distinct clinical and histopathologic features, which was originally described by Winer(1952) as solitary congenital no3ular czlcification of the skin. Although the lesions are usually solitary and congenital, subs aquent investigators reported multiple lesions and later onset. Clinically, th. leions are small hard. yellowish-white warty nodules developed. usually on the face and mostly in children and histopathologically are subepidermal calcified mass with s cvn4ry epidermal changes. Although the pathogenesis is still unexplained, it s seems that the disease is not associated with any systemic or cutaneous disease or any biochemial abnormalities. We present a first recorded case of subepidermal calcified no3ules developed on the left the a Korasn female, aged 23, which has been present for 7 years. Shave biopsy showed typical histopathologic and histochemical features of the subpidermal calcified nodules. Literature were reviewed.

There have been no standard treatments for recurrent aphthous stomatitis, and clinical management is usually directed toward symptomatic relief. Recent immunological investigations have focused on possible imrnunopathogenesis of the disease. Several reparters suggested that levamisole, nonspecific immune-stimulator, had a beneficiaI effect in controlling attacks of recurrent a,phthous stomatitis and in reducing subsequent episodes. The present study was undertaken to evaluate the therapeutic effectiveness of levamisole in patients with recurrent aphthous stomatitis. A total of 8 patients who had had recurrent aphthous stomatitis for 2 to 20 years and who had experienced at least one episode per month were selected for this study from the department of dermatology, National Medical Center, through March 1979 to September 1979, Levamisole (Decaris') was given 150mg, p.o., once daily on 3 consecutive days every week for 2 months. Tbe results were as follows. 1) One patient had to have levamisole discontinued due to a high fever and exacerbations of tbe oral ulcerations. 2) 5 patients showed beneficial effects in reducing tbe number, frequency, pain and severity of recurrent aphthous stomatitis. 3') One patient showed no therapeutic response. 4) One patient, who has experienced new oral ulcerations continuously before starting levamisole, showed no recurrences of the lesions during the follow-up period of 3 months. 5) Side effects during levamisole administration were transient and generally mild, They included nausea, headache, dizziness and high fever.

We compared the sensitivity and practicability for the direct examination of fungal hypae between the specimens treated with mixed Chlorazol black E solution and simple KOH(potassium hydroxide) solution in 118 cases of superficial myosis. The results were as follows: Higher positivity of fungal hypae in the specimens treated with mixed Chlorazol black E solution(99. 2%) than simple KOH solutiion(87. 3%.). 2, It was time-saving and easy to detect fungal hypae in the specimens treated with mixed Chlorazol black E solution than simple K(3H solution.

The prevalence of dermographism in 96 patients of acute or chronic urticaria was studied using dermographic tester. The results were summarized as follows : 1. The prevalence rate of dermographism in acute or chronic urticaria was 26.0% (25/96). 2. Dermographism was more common in acute or chronic urticaria than in the general population(p<0.005). 3. There was no significant difference in the prevalence rate of dermographiam between acute and chronic urticaria. 4. The prevalence rate of dermographism was not significantly correlated with the level of serum IgE.

We reviewed the clinical features and the skin biopsy slides of 27 patients who were diagnosed as PLEVA clinically or histapathologically in order to evaluate the clinical characteristics and the specific histopathological findings of PLEVA. The results were as follows : l. 13 of these 27 cases(48%) were confirmed as PLEVA. 2. PLEVA was more frequent in males(85% ), most of whom were young adults. 3. In most cases of PLEVA, the predilection site was on the trunk and extremities, and mild pruritus was a characteristic complaint. 4. Most cases of PLEVA were treated with tetracycline or PUVA therapy with temporary remission, but this therapy did not decrease the rate of recurrence. 5. Some histopathological findings previously described as typical in PLEVA(eg, trapped RBC in the epidermis, exocytosis of lymphocyte, dermal hernorrhage and lymphocytic perivasculitis) seemed not to be specific and were often seen in a variety of other dermatoses. 6. The histopathological findings of linear parakeratosis(85%) and dyskeratotic cells in the middle and upper epidermis(92% ) seemed to be significant findings for PLEUA. 7. The above mentioned histopat,hological findings for PLEVA were frequently found from the vesicular lesions or necrotic hemorrhagic papules.

Age of onset varied from 13 months to 58 years with a mean of 26. 0 years and 68% of cases belonged to 15 years to 84 years. 4. Seasonal incidence was 32% in winter, 27% in summer, 22% in autumn and l9% in spring. 5. iMild prodromal symptoms developed in 8 cases(%) and itching was noted in 58 cases (61%), which was mild to moderate exeept for severe itching in 2 cases. 6. Herald patch was found in 42 cases (44%) and the predilection sites were the trunk and the thighs. 7. Daughter lesions could be classified into macular type 69 cases (73g), pa.pular type 22 cases (23%), pustular type 2 cases (2%), urticarial type 1 case (I,3 and purpuric type 1 case (1%) They appeared on the back (79%), the chest (74%), the abdomen(73%), the thighs (47%), the upper arms (40%), the lower legs (24%),the forearrns (22%), the neck (16%), the face (7 %), dorsa of the hands (4%) and dorsa of the feet(2%).
