임영희(Young-Hee Lim),이현유(Hyun-Yu Lee),장명숙(Myung-Sook Jang) 한국식품영양과학회 1993 한국식품영양과학회지 Vol.22 No.2

가열시간에 따른 튀김유와 튀김횟수에 따라 제조한 유과의 품질에 미치는 영향을 조사하였다. 가열 16시간까지 튀김유의 산가와 과산화물가는 각각 0.08에서 0.23, 0.8에서 1.78까지 완만하게 증가하였으나 유과제품의 품질에는 큰 영향을 주지 않았다. 튀김유와 유과의 지방산조성변화는 가열시간이 경과함에 따라 불포화지방산인 oleic acid와 linoleic acid가 감소한 반면 포화지방산인 palmitic acid는 증가하였다. 가열시간에 따른 유과와 콩기름의 색깔변화는 콩기름에서 특히 현 저하여 심한 갈변현상을 보인 반면 유과제품에서는 큰 차이를 보이지 않았으며, 관능검사 결과 가열시간이 증가함에 따라 전반적인 기호도는 저하하였지만 유의적인 차이는 보이지 않았다. The effect of soybean oil on frying time and number of frying treatment on quality of Yu-kwa (Korean traditional rice cookie) were examined. As the frying time increased, acid value and POV were increased from 0.08 to 0.23 and 1.78, respectively. But the quality of Yu-kwa was not influenced by the frying time. And as the. frying time increased, unsaturated fatty acid (oleic and linoleic acid) was decreased, while saturated fatty acid (palmitic acid) was increased. The color was drastically changed on frying oil which showed a dark brown color, but there was no difference in Yu-kwa. As the frying time increased, acceptability was decreased on sensory evaluation, but significant difference among samples tested within significant level 5% was not revealed.

이창우,유희준,양홍윤,전재홍 한양대학교 의과대학 1996 한양의대 학술지 Vol.16 No.2

We reviewed 4,173 new out-patients visited dermatology clinic of Hanyan University Kuri Hospital (from November 1995 to October 1996) to study the prevalence of common dermatoses occurring in this region (northeastern area of Kyounggi province) and compared to those of other Korean data. Among 4,173 new out-patient, 1,866(44.7%) were male, and 2,307(55.3%) were female. Fifteen common dermatoses were found to be contact dermatitis(13.0%), dermatophytosis(9.1%), atopic dermatitis(8.4%), seborrheic dermatitis(8.1%), other eczemas(7.8%), urticaria(6.4%), acne vulgaris(4.9%), herpes zoster(3.4%), drug eruption(2.5%), bacterial infection(2.1%), psoriasis(1.9%), verruca(1.8%), vitiligo(1.4%), syphilis(0.5%), and scabies(0.5%) in order of frequency. The most frequently visited age group was those between the age 21 to 30 years old constituting 20.4% of total patients. On monthly visited number of patients, the highest was in January, and the lowest was November. The results suggest that age, sex and monthly distribution patterns in northeastern area of Kyounggi province are similar to those of other epidemiological reports in Korea except for the higher prevalences of contact dermatitis, seborrheic dermatitis and herpes zoster.

이혜정,박희옥,김유경 한국식품영양학회 1994 韓國食品營養學會誌 Vol.7 No.3

닭고기를 이용하여 소시지류의 제조 가능성을 검토하기 위하여 돼지고기와 닭고기에 인산함유 소금과 양념류를 첨가하여 cold cut을 제조하고 탈기포장하여 저장기간동안의 품질을 비교 연구하였다. 돈육 cold cut이 계육 cold cut보다 미생물의 증식이 더 빠르고 산가가 더 크게 감소하였으나 TBA가는 계육 cold cut의 증가폭이 더 컸다. 조직감 측정에서는 springeness, cohesiveness는 두 시료간에 유의적 차이를 보이지 않았다. 돈육 cold cut과 계육 cold cut의 관능검사에서는 색, 외관, 냄새에서 유의적 차이를 보였으나, 조직감, 풍미, 전체적인 수응도에서는 유의적 차이가 나타나지 않았다. 이러한 연구결과 닭고기를 이용한 소시지류의 제조 가능성을 볼 수 있었다. Cold cuts were prepared from the pork and chicken with polyphosphate salt and spices. Microorganism was more proliferated and acid value was more decreased in pork cold cut rather than chicken cold cut. Otherwise TEA value of chicken cold cut was more increased than that of pork cold cut. Textures of springeness and cohesiveness were not significantly different in both cold cuts. From sensory evaluation, color, apprearance and odor were significantly different, but texture, flavor and total acceptability were not significantly different. From these results, if we could study some antioxidants furthermore, we think it possible to manufacture cold cut from chicken.

골뱅이(Buccinum Undatum) 알레르기 : 감작률과 다른 음식물 항원과의 연관성 Sensitization rate and its relationship with other food allergens

이재영,윤성호,서유진,최정희,서창희,남동호,김윤근,민경업,박해심 대한천식 및 알레르기학회 2004 천식 및 알레르기 Vol.24 No.1

Background : The common whelk (Buccinum undatum) is one of the largest and most common snails in the North Atlantic. In Korea and Japan, common whelk is a popular eatable shellfish. Although shellfish has been known as the one of the most common causes of food allergy, there has been no published report on allergenecity and clinical significance of this sea snail. In this study, we determined the sensitization rate to common whelk and its relationship with other food allergens in allergy patients. Method : We carried out the skin prick test (SPT) with commonly consumed food stuffs in Korea including common whelk in 1700 patients over 1 year. The specific IgE to common whelk were detected by enzyme-linked immunosorbent assay (ELISA). ELISA inhibition test using sensitized sera was conducted. Results : SPT to common whelk was positive (≥2+) in 83 (4.9%) patients studied. Twenty-four (38.7%) of 62 SPT-positive patients had high serum specific IgE to common whelk. ELISA inhibition test showed significant inhibitions by abalone as well as by common whelk and, minimal inhibition were noted by shrimp. Significant correlation was also noted in specific IgE levels between common whelk and abalone (r=0.58, F<.05). Conclusion : IgE-sensitization rate to common whelk was 4.9% in allergy patients. Further stuides are needed to evaluate the clinical significance of sensitized patients to common whelk, and to confirm a cross reactivity with abalone. (J Asthma Allergy Immunol 24 : 77-84, 2004)

이수근,김재홍,양홍윤,김윤석,유희준,손숙자 대한의진균학회 1998 대한의진균학회지 Vol.3 No.1

Background: Steroid acne is a folliculitis that can result from a systemic or topical administration of steroid and has been described as showing similar clinical pictures to Malassezia folliculitis, but there have been few reports about the incidence of Malassezia in steroid acne and other acneiform eruptions. Objective: Our purpose was to describe the incidences of Malassezia in acneiform eruptions and to discuss about the relationship between clinical steroid acne and Malassezia folliculitis. Methods: The history, clinical features, direct microscopy, histopathological analysis, and therapeutic results of 125 cases with steroid acne or other acneiform eruptions were described and compared. Results: Over 80% of patients with acneiform eruption receiving systemic steroid revealed significant numbers of Malassezia in the lesional follicle. Conclusion: Steroid acne and other acniform eruptions showing discrete follicular papules and/or pustules localized to the upper trunk or acneiform facial skin lesions associated with multiple acneiform lesions on the body in the summer period should be suspected as Malassezia folliculitis.
