인체 폐암세포주에 대한 마늘과 양파 메탄올추출물의 세포독성
노숙령(Sook-Nyung Rho),한지혜(Jee-Hye Han) 한국식품영양과학회 2000 한국식품영양과학회지 Vol.29 No.5
본 연구는 폐암세포주인 NCI-H522와 NCI-H596에 대한 마늘, 양파의 메탄올 추출물과 이들의 혼합물의 세포독성을 비교하기 위해 in vitro에서 MTT assay를 통해 조사하였다. 마늘추출물군, 양파추출물군 및 혼합물군 모두는 폐암세포주인 NCI-H522, NCI-H596에서 세포독성을 나타내었다. 세 군 모두는 추출물의 농도에 의존적이었는데 1 mg/mL media에서 가장 높은 세포독성을 나타내었고 각 세포주에서 각각의 다른 감수성을 보였다. 마늘추출물군의 경우 NCI-H522에서 26.4%, NCIH596에서 34.8%의 세포생존율로 NCI-H522에서 더 높은 세포독성을 보였고, 양파추출물군에서는 NCI-H522의 경우 47.7%, NCI-H596에서 24.5%로 NCI-H596에서 더높은 세포독성을 보였다. 마찬가지로 혼합물군의 경우NCI-H522에서 57.1%, NCI-H596에서는 48.4%의 세포생존율로 세포독성을 나타내었다. IC_(50)값에 대해서 NCIH522와 NCI-H596의 경우 각각 마늘추출물군에서는 0.84, 0.88 mg/mL를 양파추출물군에서는 1.04, 0.78 mg/mL를 혼합물군에서는 1.21, 1.07 mg/mL를 나타내었다. 이상의 결과를 종합해 볼 때 마늘과 양파의 유기용매추출물이 폐암세포주에 대해 세포독성을 나타냄을 알수 있었으며 세포주에 따라 세포독성 정도의 차이가 있었다. This study was designed to investigate the cytotoxic effect of methanol extract of garlic, onion and those mixture on two kinds of human lung cancer cell lines (NCI-H522, NCI-H596) using MTT assay. MeOH extract of garlic, onion and those mixture showed cytotoxic effect on both NCI-H522 and NCI- H596. The growth of the cancer cells exposed to medium containing garlic, onion extracts and those mixture was inhibited dose-dependently. The growth of NCI-H522 was inhibited more in the garlic extract than in the onion extract, but that of NCI-H596 was inhibited highest in the onion extract. IC50 values of garlic extract on NCI-H522 and NCI-H596 were 0.84 mg/mL, 0.88 mg/mL and those of onion extract were 1.04 and 0.79, respectively. And the mixture of garlic and onion extracts also inhibited the growth of both NCI-H522 and NCI-H596 cells.

The purpose of this paper is investigation on the consumption and the nutrition of marketing fermented milk in Korea.<br/> The objectives were selected randomly from 3 cities in Jeonbug province, Jeonju, Iri and Gunsan, and they were grouped into students, housewives, patients, and officers from July to September 1980. (male: 591, Female; 673, total: 1,264).<br/> Findings in detail are summarized in Table 1 - 15.<br/> Among the many kinds of marketing fermented milk in Korea, products from the five manufacturers, whose numbers of Lactic acid bacteria were standardized, were sampled and divided into groups, A,B,C,D,E.<br/> The constituents of nutrition of them were analyzed by HPLC and AAS.

Numerous studies on the ablactation have been reported since Jundell’s report in 1924.<br/> This paper deals with the comparison in nutritional values, composition, economical sense and recommended dietary allowances to Korean infants of the weaning foods sold in Seoul, Jeonju and Gunsan together with the analysis of nutritional compositions of the most recommendable weaning food among those investigated.<br/> The results obtained from this study were;<br/> 1. Among ten kinds of the weaning foods produced i Korea, only nine sorts could be purchased in Seoul, seven in Jeonju and five in Gunsan.<br/> 2. It was difficult to compare directly the compositions of the weaning foods each other because of the differences of the unit indicated.<br/> 3. Not only the price of the same product in the same area was differentiated by 10 to 100 won but also the standard of nutritional composition was not identically indicated by the company produced.<br/> 4. Since the amount of directed dietary intake was much more than the actual nutritional requirements of Korean infants, waste of money was considered, if used according to the directions.<br/> 5. The nutritional compositions of the most recommendable weaning food among those investigated were indicated in Table.<br/> 6. More nutritious and economical weaning food adequate to Korean infants must be developed through further scientific, in vivo experiments.

Coffee is a popular beverage with many people at home and in the tea-room. Caffeine is a major chemical compound of coffee. A little caffeine is a stimulant to the movement and spiritual nerve, but much caffeine influences sleep, nervousness, non-concentration, headache and giddiness depending upon each person.<br/> The writer expresses the result of the caffeine content in the coffee which is collected from the coffee- shops of Seoul.<br/> The contents are as follows :<br/> 1) Caffeine content of the coffee of the tea-room was researched dividing into the central Seoul city and the outskirts of Seoul.<br/> 2) Caffeine content of the coffee in the outskirts tea-rooms is 0.32~1.23㎎/ml and the average is 0.546㎎/ml (SD 0.19).<br/> 3) Caffeine content of the coffee of the central city is 0.34~0.73㎎/ml and the average is 0.513㎎/ml(SD 0.12).<br/> 4) There was no difference between the outskirts and the central city.<br/> 5) Caffeine content of the coffee of the tea-rooms according to each season is going to be researched.
