This study was conducted to develop functional muffin in which grape seed extract(GSE) was added at 0, 0.5, 1 or 2% levels and to evaluate the quality characteristics. The volume of muffin decreased with the increasing GSE content, but no significant differences were observed. The weight and height of muffins increased with the increasing GSE content. The incorporation of GSE in the product lowered lightness(L value) and increased redness(a value). The mechanical texture parameters including hardness, springiness, gumminess and brittleness increased with the increasing GSE levels. Sensory analysis showed that muffin prepared with 0.5% GSE was considered to be as acceptable as control, based on hedonic scale ratings given by untrained taste panel.

Aplasia cutis congenita is an anomaly characterized by absence of localized areas of the integument. The most common type of aplasia cutis congenita is a circular or oval, sharply outlined ulcer 1 to 3cm in diameter on the vertex of the scalp at the level of the posterior fontanel. Two cases of aplasia cutis congenita are presented. The first case was in a male newborn infant with a localized defect on his scalp. The second case was also in a male newborn infant who had extensive symmetrical involvement of his heels. No similar conditions and associating other congenital anomalies were found in the family members of reported cases.

Cutaneous leishmaniasis (oriental sore) is usually a self-limited infection of the skin caused by the protozoan Leishmania tropica. The disease is endemic to the Mediterranean, Asia, Africa, and the Middle East. It has been seen in this country among many Korean technical experts and labourers working in the endemic areas of the disease. Our patient had acquired cutaneous leishmaniasis in Saudi Arabia and it had remained active for six months. He had been treated with antimony and metronidazole but failed because of severe side effects. And then we treated the patient witb cryosurgery and the skin lesions were followed by resolution with cosmetically acceptable scar in 4 months. The brief review of literature on the treatment of cutaneous leishmaniasis was undertaken.

이 실험 연구는 초저온 평판 표면에서 발생하는 착상 특성을 조사 하였다. 초저온에서는 일반 저온의 착상 과정과는 다르게 착상 초기 단계에서는 냉각면 선단에만 매우 빠르게 서리층이 나타는데 반해, 냉각면 후단에는 상대적으로 두께가 낮은 서리층이 냉각면 선단의 서리층과 분리된 채로 형성된다. 공기 유속 증가에 따라 후단 서리층 분리현상은 약화되었고, 습도 증가는 큰 영향을 끼치지 않았다. 공기 유속 증가 및 습도 증가에 따라 선단과 후단의 두께비는 감소하였다.

The clinical and histopathological analysis was done on 28 cases of basal cell epithelioma encountered in the Department of Dermatology, Ewha Womans University Hospital during the past 7 1/2 years period from January 1976 to June 1983. The results obtained were summarized as follows : 1) Of 28 patients, 15 cases were male and 13 cases were female with ratio of 1.16:1. 2) Average age was 53.5 years ranging from 15 to 90 years with the highest incidence rate in the age group 60-69 years. 3) Three cases of basal cell epithelioma in the young age group developed from xeroderma pigmentosum. 4) The average duration of disease was 7.5 years ranging from 1 to 20 years. 5) Twenty seven cases(96.4%) occured on face comprising 11 cases on nose, 8 cases on lower eyelid, 3 cases on cheek, each 1 case on forehead, eyebrow, upper lip, angle of mouth and mandible, and remaining 1 case occured on back. 6) The most common noduloulcerative lesion was observed in 7 cases(25.0%), and then followed by(in order)adenoid type and sclerosing type 6 cases (21.4%) respectively, mixed type 5 cases(17.9%) and keratotic type 4 cases(14.3%).

Over-exposure to sunlight may result in sunburn, pigmented skin lesions, solar keratosis, premature aging of skin, or cancer in human skin. Sunscreens protect the structure and function of the human integument from the actinic damage. This protective effect is afforded by active ingredients of sunscreens through absorption, reflection, and/or scattering of the solar radiation impinging on the skin. There are oral and topical sunscreens. Para-aminobenzoic acid(PABA), PABA esters, benzophenones(BZ), cinnamates, salicylates and anthranilates are the topical sunscreens absorbing solar radiation. Most of them absorb UVB, but BZ absorb both UVB and UVA. These investgators observed the effect of the sunscreens by calculating sun protection factor(SPF) before and after application of the sunscreens in human skin. To my knowledge, there are no papers which evaluate morphological changes in the epidermal melanocytes after UVB or UVA irradiation following application of the sunscreens. In this experiment, a total of 150 adult male black mice(C57BL) was used. The animals were divided into one control (application of hydrophilic ointment base) and four experimental(application of PABA, Cinnamate, BZ or homomenthylsalicylate (HMS)) groups. Each group was irradiated by UVB and UVA, respectively. Each of the 5 groups were divided into 5 subgroups according to the days of UV light irradiation ; subgroup A for 2 days, B for 4 days, C for 6 days, D for 8days and E for 10 days. The daily doses of UVB and UVA were 50mJ/cm^2 and 5J/cm^2 respectively. YS UVB-400 and Waldmann UV 800 were used as a light source of UVB and UVA. Skin specimens were taken from both ears of the animals 24h after the last irradiation. The split-DOPA preparation was carried out for observation of the numbers and morphological changes of the epidermal melanocytes. The results are summarized as follows; 1. Changes in the numbers of the epidermal melanocytes : The numbers of the epidermal melanocytes markedly decreased in the experimental groups, especially in the group of PABA application(p<0.01), compared in the control group under UVB irradiation (p<0.01). However, only the group of BZ application showed a significant decrease in the numbers compared to the control group under UVA irradiation(p<0.01, p<0.05). 2. Changes in the size of the epidermal melanocytes ; Each experimental group, especially the group of PABA application (p<0.01), showed a significant decrease in the sizes of the epidermal melanocytes under UVB irradiation(p<0.01, p<0.05). On the other hand, only the group of BZ application showed a significant decrease in the sizes compared to the control group under UVA irradiation(p<0.05) From the results, it seems to be sure that PABA, Cinnamate, BZ, HMS can protect UVB from sunlight in the skin of black mice. Furthermore, BZ was effective for protection of UVB and UVA together.

피지선 증식증 1예

Sebaceous hyperplasia, also called senile sebaceous hyperplasia refers to a benign enlargement of normal sebaceous unit in the old age group. The lesions, single or multiple, elevated, cream to yellowish colored round papules with frequent central umbilication have a predilection for the forehead and cheeks. We present an atypical case of sebaceous hyperplasia on a 31-year-old man. About 15 years ago, a small skin colored papule developed on his right cheek without pre-existing skin eruption or trauma history. The asymptomatic papule enlarged slowly reaching up to a walnut sized plaque.

Effects of Addition of Herbs on Pork Patties during Storage

This study was conducted to investigate the effects of herbs (dill weed, fennel seed and rosemary) on color stability and lipid oxidation of ground pork patties during storage at 2oC and -20oC. Lipid oxidation was determined by the thiobarbituric acid reactive substances (TBARS) method. Fennel seed was identified as being the most effective ingredient in terms of meat redness (Hunter a-values) during storage at 2oC (p<0.05). Patties treated with rosemary had lower Hunter a-values than control, and dill weed was the least beneficial in influencing meat redness, having significantly lower a-values than control patties. During frozen storage at -20oC, no significant differences in a-values were observed between the control patties and those treated with fennel seed. Patties treated with rosemary had lower a-values than control and patties with dill weed had negative a-values throughout storage. The cooking process increased Hunter L-values and decreased a-values in all patty samples. TBARS values increased during storage. Rosemary displayed excellent antioxidative activity as evidenced by the completely inhibition of TBARS formation of cooked pork patties. Dill weed and fennel seed also exerted an intermediate but significant antioxidant effect during storage (p<0.05).
