This study aimed to investigate Anisakis simplex infection degree in sea fishes. Forty-two squids(Todordes pacificus), 21 belt fishes(Trichiurus lepturus), and 48 mackerels (Scomber japonicus) were collected from sushi bats, wholesale and retail markets. Fourteen of 42 squids from retail markets were infected 4th 3rd stage larvae of Anisakis simplex. The infection rare of belt fishes collected from wholesale and retail markets showed 22.8% and 74.2% respectively. Pony-one of 48 mackerels were severely infected with 3rd stage larvae, Anisakis simplex is identified as the prevalent helminth pathogen in squid, belt fish, and mackerel which is the common fish protein source.

The market of organic produces which are cultivated without insecticide or chemical fertilizer is growing very fast. However, several food poisoning cases are caused by microbiologically contaminated organic vegetables. Therefore the aim of this research is to compare the microbiological contamination level of organic and inorganic vegetables produced in Korea. Each 10 samples of organic and inorganic vegetables (Chicory, Romaine, Red Lettuce, and Red chard) were collected from retail market and submitted to the microbial evaluation. The number of total microbes, Escherichia coli 0157, Salmonella spp., and Staphylococcus aureus were investigated with the standard methods of Food Code in Korea. Statistical analysis of each group was performed using SAS (version 9.1) program. The average number of total microbes and Staphylococcus aureus in organic vegetables were much lower than that of inorganic vegetables (6.91 vs. 6.44; 7.04 vs. 6.89 respectively) but contamination of E. coli 0157 and salmonella spp. were vice versa. Our data may support that organic vegetables are not free from microbiological contamination which can cause food poisoning.

The aim of this study was to investigate the virulence factor profiles of Escherichia coli strains isolated from pork and chicken meats purchased from retail markets in Korea. From 943 pork and 142 chicken meats, 217 isolates of E. coli were cultured. The presence of 11 virulence factors (elt, estI, estII, astA, stx, cdt, cnf, agg, inve, eae, afa) were detected by polymerase chain reaction. Forty one (18.9%) of 217 E. coli isolates carried at least one virulence factor. Among 175 E. coli isolates from pork, the detection rate of astA, elt, eae, estII, estI, afa, and cnf were 6.9%, 4.6%, 4.6%, 4.0%, 2.3%, 1.1%, and 0.6%, respectively. However, stx, agg, and cdt were not detected in our isolates. Therefore, we conclude that astA is the most prevalent virulence factor in E. coli isolates contaminated in pork and chicken meats in Korea.

This study was performed to investigate Apolipoprotein E phenotypes and the relationship among lipid levels, nutrient intakes, lifestyles and risk factors between subjects with and without hyperlipidemic risk. The data were collected from 675 industrial male workers who had completed annual medical examination. Compared to the normal group, the hyperlipidemic risk group in Apo E3 and E4 had significantly higher BMI (p < 0.05) and showed significantly higher body fat (%), waist circumference and WHR in all types of Apo E (p < 0.05). In addition, the hyperlipidemic risk group had significantly higher total cholesterol, LDL-cholesterol, triglyceride and AI than the normal group in all types of Apo E (p < 0.05). Intakes of protein, calcium, phosphorus, iron, vitamin A, vitamin B1, vitamin B2, vitamin C and niacin in Apo E3 were significantly lower in the hyperlipidemic risk group than in the normal group (p < 0.05). In the logistic regression analysis, after adjustment for other factors, Apo E2 + E4, waist and WHR were the significant risk factors associated with hyperlipidemia, but protein intakes were associated with significantly lower risks of hyperlipidemia (p < 0.05). In conclusion, genetic factor (Apo E2 or Apo E4), anthropometric index and nutrient intake seem to influence hyperlidemic risk. Further studies and efforts will be needed to evaluate the independent relationships among hyperlipidemic risk factors. (Korean J Nutr 2008; 41(5): 402 ~ 413)

유착방지제를 개발하기 위해 천연고분자인 K-Carrageenan을 이용하여 가시광 경화형 carrageenan 유도체(FCm-Carrageenan)를 제조하였다. Carrageenan은 생분해성, 생체적합성 등과 같은 특성을 가진 천연고분자이다. Riboflavin은 무독성, 생체적합성을 가지는 천연 광개시제이다. Riboflavin은 가시광 경화형 carrageenan 유도체에 광경화를 유도한다. ¹H NMR(proton nuclear magnetic resonance), GPC(gel permeation chromatography) 분석을 통하여 F-Cm-Carrageenan이 제조된 것을 확인하였으며 가시광 조사시간에 따른 광경화 정도를 판단하기 위해서 광경화실험을 진행하였다. 또한 유착방지제로 응용가능 여부를 판단하기 위해서 세포독성 실험, 유착방지 실험, 세포투과 실험을 진행하였다. 따라서 가시광 경화형 carrageenan 유도체는 새로운 형태의 유착방지제로서 응용될 수 있다고 사료된다. To develop anti-adhesion agent using photo-reaction, visible light curable carrageenan derivatives (F-Cm-Carrageenan) was prepared by using K-Carrageenan which is natural polymer. Carrageenan is a natural polymer having properties such as bio-degradability and bio-compatibility. Riboflavin is a non-toxic, bio-compatible natural photo-initiator. Riboflavin induces photo-crosslinking in visible light-curing carrageenan derivatives. ¹H NMR (proton nuclear magnetic resonance) and GPC (gel permeation chromatography) analysis were conducted to confirm that F-Cm-Carrageenan was prepared. Photo-curing test was conducted to determine the degree of photo-curing with visible light irradiation time. To evaluate the applicability as an anti-adhesion agent, cytotoxicity test, anti-adhesion test and cell penetration test were conducted. Therefore, it is considered that the visible light curable carrageenan derivatives can be applied as a new type of anti-adhesion agent.
