This study evaluated the effect of a combination of acetaminophen (AAP), vitamin C (VC) and thioctic acid (TA) on reducing serum cortisol concentrations in mice with foot-and-mouth disease (FMD) vaccination. For 5 days from 3 days before FMD vaccination to 2 days after vaccination, mice were orally administered with AAP 600 mg/kg feed (n=25, AAPT), combination of AAP 600 mg and VC 200 mg per kg feed (n=25, AVCT) and combination of AAP 600 mg, VC 200 mg and TA 20 mg per kg feed (n=25, AVTT), respectively. From day 1 to day 7 after FMD vaccination, the cortisol concentration of all groups treated with the drug was significantly decreased compared to that of the positive control group with FMD vaccination (p<0.05). In conclusion, the combined treatment of AAP, VC and TA was the most effective in relieving stress from FMD vaccination compared to the single treatment.

본 연구는 현재 유통 중인 다이어트 제품 62건에 대한 부정유해물질의 실태조사를 위하여 비만치료제 및 그 유사물질 6종(오르리스타트, 시부트라민, 데스메틸시부트라민, 디데스메틸시부트라민, 클로로시부트라민, 클로로시펜트라민)과 중금속(납, 카드뮴, 비소) 함량을 조사하였다. 연구결과, 다이어트 제품 62건에 대하여 비만치료제 및 그 유사물질 6종은 검출되지 않았다. 중금속은 납, 카드뮴, 비소 각각 다류의 경우 ND-0.177 mg/kg, 0.002-0.233 mg/kg, 0.001-0.188 mg/kg, 캔디류의 경우 ND-0.370 mg/kg, 0.003- 0.057 mg/kg, 0.007-0.120 mg/kg, 체중조절용조제식품의 경우 ND-0.055 mg/kg, 0.012-0.045 mg/kg, 0.010-0.163 mg/ kg의 함량을 나타냈다. 기준 규격이 설정되어있지 않은 기타가공식품의 경우 납, 카드뮴, 비소 각각 ND-2.324 mg/ kg, 0.004-0.936 mg/kg, 0.003-21.247 mg/kg의 함량을 보였으며, 비소의 경우 2건이 PTWI 기준치 이상의 수치를 보였다. 결과적으로 식품군의 안전관리를 위하여 향후 기준 규격이 없는 기타가공식품 유형에 대한 적절한 기준 설정이 필요할 것으로 사료된다.

본 연구는 불법적으로 식품에 사용될 수 있는 부정물질 11종에 대한 안전관리 강화를 위해 정량 및 정성 분석이 가능한 HPLC-DAD와 LC-MS/MS를 검증하기 위해 수행 되었다. 확립된 시험법은 AOAC 가이드라인에 따라 직선성, 정밀성, 정량한계 및 회수율 등을 통해 유효성을 확인 하였다. 본 실험에서 정량한계를 포함하여 검량선을 작성 하였고, 모두 0.99 이상의 직선성을 확인하였다. 또한 정확성은 LC (90.0-106%), LC-MS/MS (83.0-114%) 이고, 정 밀도는10% 이하로 재현성이 우수하였다. 확립된 시험법은 식품 중 부정물질 안전관리 및 모니터링에 활용될 것으로 사료된다.

The aim of this study was to evaluate the status of consumption and consumer satisfaction of dietary fiber supplements. The survey was conducted using a self-recorded questionnaire developed to meet the purpose of this study. The characteristics of the subjects who have taken dietary fiber supplements in the past are as follows: distributions of socioeconomic variables showed that the highest-ranked group(the group that reported the highest consumption of dietary fiber supplements) was professionals with a college degree or higher degree. In addition, the highest-ranked group were the most healthy, nonsmokers and reported drinking habits of ‘1～2 times/week’. Regarding the health status of those surveyed, digestive disease and constipation were the most common complaints. The majority responded with ‘health concerns’ to the question that asked the reason for their purchase of the dietary fiber supplements. Three major places respondents could find dietary fiber supplements were ‘through the internet’, ‘the market’, ‘the pharmacy’ in descending order. The compositions of dietary fiber products varied. ‘konjac’, ‘cellulose’, ‘psyllium husks’ were the most popular components consumed by the subjects. The average duration of product consumption was less than one month. In terms of satisfaction levels(satisfaction was ranked from 1 to 5), ‘taste’ and ‘type’ scored the highest in satisfaction levels while ‘price’ ranked the lowest. When subjects were asked about self-awareness regarding the physiological efficacy of dietary fiber supplements, the responses were positive in ‘bowel movement’ and ‘weight loss’. Further research is required to improve the quality of dietary fiber supplements in order to assist consumers in selecting the appropriate products.
