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%.

We observed 17 cases of cafe au lait spots histopathplogi ally. Out of 17 cases, 9 cases were neurofibromatosis with neurofibromas, 6 cases were neurofibromatosis without neurofibroma, and 2 cases were normal healthy persons. The results were as follows. l. In all 17 cases, melanin pigment was increased in melanocytes and keratinocytes. 2. Griant pigment granules were identified only in 3 cases of neurofibromatosis with neurofibromas.

We observed clinical and histopathological findings of porokeratosis in 16 cases which comprised 2 linear types, 4 superficial disseminat:ed forms, 4 disseminated superficial actinic porokeratosis and 6 plaque types. From the observation, the following results were obtained. l. Clinical results 1) Eleven cases were men, 5 cases were women, and the sex ratio was 2. 2 to 1, age distribution was from 6 to 61 years (mean age: 34. 2years), and the distribution of age of onsets was from 2 to 52 years(mean age of onset' 23. lyears). 2) Four cases had family history of porokeratosis, but linear forms did not. 3) Nine cases had pruritus especially, all cases of DSAP and DSP except 1 case complained pruritus. 4) Tmo cases of DSAP had tendency of summer exacerbations. 2. Histopathological results 1) Cornoid lamellae were prominent in all cases of plaque types and linear types, and minimal in all cases of DSAP and DSP except 1 case. 2) Epidermis between the cornoid lamellae were normal or acanthotic in all cases except 1 case of plaque types and linear types, and were atrophic in 5 cases of 8 cases in DSAP and DSP.

The prevalence of dermographism in the general population of Korea was studied using a dermographic tester on 1, 074 persons(M: 489, F: 585, M/F= 1/l. 2). The result was summarized as follows: 1. The prevalence of dermographism from the pressure of 4, 800 Gm/sq. cm (pressure 2) was 6. 7%. 2. There were no significant difference in the prevalence between male(6.3%) and female(7%) (p>0. 1). 3, The peak age group of dermographism was third(9.4%), fourth and second decades in decreasing order.

Proliferating trichilemmal tumor is one of rare benign tumors of the skin appendages, considering as hamartoma of the terminal hair follicle, isthmic segment of the outer root sheath. We report a case of numerous proliferating trichilemmal tumors admixed with ordinary trichilemmal cysts with femilial history in 64-year-old man. He has total 157 lesions, which are chiefly located in scalp (48), back (32), and also face, neck, trunk, extremities. Histologically, the tumor is composed of irregularly arranged and ansatomosed trabeculae, lobules, or sheets of proliferated trichilemmal squamous epithelium with peripheral palisading of the basaloid cells. Several layers of squamoid or ovoid cells have PAS-positive clear cytoplasm. And it also shows abrupt amorphous, trichilemmal keratinization. Some squamous eddies with mild cellular atypism are associated, but definite invasion or other evidence of the malignancy is not found. usual multiple trichilemmal cysts are admixed with tumor and occasionally exhibit connection between them.

The purpose of this study was to investigate children's nutrient intakes by school lunch. Evaluation of nutrient intakes by school lunch for three days was conducted with 86 children in urban and 64 children in rural of Jeonbuk area. The results of this study were as follows. 1) With respect to amounts of provided nutrients in school lunch, CPF (carbohydrate : protein : fat) energy ratio was 48.6 : 19.7 : 31.6 in urban and was 46.7 : 20.5 : 32.7 in rural. Compared to 1/3 RDA (RDA) of children for 10-12 years, folic acid and zinc were provided below 50 % of RDA. Protein, fat, phosphorus, vitamin B1, vitamin B2, niacin, vitamin C and vitamin E were provided above 125 % of RDA. There were no differences in amounts of provided nutrients-except calcium, vitamin A, vitamin B6, folic acid and zinc-between urban and rural. 2) With respect to amounts of nutrient intakes, CPF energy ratio was 51.1 : 17.4 : 31.5 in urban and 47.5 : 19.7 : 32.7 in rural. Compared to RDA, folic and zinc were below 50 % of RDA. Iron and vitamin B6 were below 75 % of RDA. Protein, fat, phosphorus and vitamin E were above 125 % of RDA. There were significant differences in nutrient intakes between urban and rural. The children in rural showed higher levels of nutrient intakes-energy, carbohydrate, protein, fat, calcium, phosphorus, iron, zinc, vitamins and folic acid-compared to those of children in urban. These results suggest that programs are needed for providing adequate nutrient intakes for children in school lunch and for improving nutrient intakes of children in urban.

The prevalence of dermographism in 249 Korean pregnant and puerperal women was studied using a dermographic tester. The result was summarized as follows: 1. The prevslence rate of dermographism was 8.0%(20/249). 2. The prevalence rate of dermographism was not significantly correlated with the stages of pregnancy(p>0.1). 3 There was no significant difference in the prevalence rate of dermographism between the pregnant and puerperal women(8.0%) and the control group of Korean women in the same ages(9.5%) (p>0.1).

We report a case of Waardenburgs syndrome in 18-year-old male patient who has total deafness of the right ear, heterochromia irides, hypopigmented patches on the face and trunk, and disseminated lentigines on the entire body surface since birth. His 51-year-old mother also has total deafness, heterochromia irides, white foreloek, and disseminated lentigines on the entire body surface. The patient with this disorder may complain of pigmentary abnormalities, and we believe dermatologists should pay more attention to systemic signs of the congenital pigmentary disorders.
