        The purpose of this studyis to conduce the survey of three groups of college women living in different residential districts, Seoul, Gyeonggi-do and a district, each other, analyze the actual condition of wearing blue jeans, comparative investigate actual condition in each residential district of wearing blue jeans and cognition by change of crotch length and trend through comparison of cognition on dressed blue jeans with short crotch length. By which investigation, it was intended to understand their condition and propose of blue jeans as may offer fit with short crotch length. As the result of this study, it presented college women had hipbone blue jeans in order of 2~3 and more than 4 in all of residential districts, they purchased hipbone blue jeans with crotch length in order of for middle crotch(23 ㎝) and short crotch(21㎝) commonly in all of residential districts, and they care a lot for exposing back waist and hip of hipbone blue jeans without reference to residential district. They had a bad feeling for exposure, and as an alternative to deal with this, they answered mostly on ‘wearing hipbone underwear’ or ‘wearing long upper garment’, and there was significant difference between residential districts in silhouette and exterior fitness of crotch length among important factors when wearing hipbone blue jeans.

        소핵시험은 세포분열 단계 중 간기 세포의 세포질 내 소핵 유무를 조사함으로써 유전독성을 평가하는 시험법이다. 최근 화장품 안전성 평가에 동물실험을 금지하거나 최소화하려는 노력이 확산되고 있어 유전독성 평가에 있어서도 기존의 동물실험이 아닌 새로운 in vitro 시험법이 요구되고 있다. 본 연구에서는 3차원 배양 인공피부모델인 KeraSkinTM을 이용하여 도포 처치된 물질의 유전독성을 평가하였다. 2종의 유전독성물질인 mitomycin C (MMC)와 methyl methanesulfonate (MMS)는 농도 의존적으로 세포독성과 소핵 형성이 유도 된 반면, 대조물질인 4-nitrophenol (4-NP)와 trichloroethylene (TCE)에서는 농도 의존적으로 세포독성은 관찰되었으나 소핵은 형성되지 않았다. 따라서 인공피부모델을 이용한 소핵시험이 화장품과 같은 피부적용물질 의 in vitro 유전독성 평가에 유용할 것으로 사료된다.

        Background : This study aimed to investigate the antioxidant and anti-inflammatory activities of water chestnut (Trapa japonica Flerow) extract. Methods and Results : The antioxidant and anti-inflammatory activities of 100% methanol extract of water chestnut were investigated. The methanol extract was evaluated for its total phenolic and flavonoid content, DPPH•(1,1-diphenyl-2-picrylhydrazyl) free-radical scavenging activity,reducing power, andeffect on nitric oxide (NO) production and cell viability using real-time polymerase chain reaction (qPCR). The total phenolic content was 438.31 ㎍ allic acid equivalent (GAE)/㎎ extract and the total flavonoid content was 61.40 ㎍ quercetin equivalent (QE)/㎎ extract. In addition, results revealed the extract possessed antioxidant activity (DPPH• free-radical scavenging activity) with IC50 value of 5.28 ㎍㎖ The reducing power of the extract was assayed spectro photometrically and showed Abs of 0.71 at 100 ㎍㎖ Furthermore, extracts of water chestnut exhibited no cytotoxicity in RAW 264.7 cells. In addition, the NO assay revealed that LPS-induced NO production was significantly inhibited following treatment with water chestnut extracts. The expression of pro-inflammatory proteins such as inducible nitric oxide synthase (iNOS) and cyclooxygenase (COX)-2 decreased in a concentration-dependent manner. The water chestnut extract also decreased tumor necrosis factor α (TNF-α) release. Conclusion : Therefore, the present findings provide scientific evidence for the nutritional potential, chemical composition, and biological activities of Trapa japonica Flerow anddemonstrate its potential use as a functional food forapplication in the pharmaceutical industry
