오늘날 현대인들의 식생활방식 중 과다한 열량의 영양소 섭취로 인하여 초래되는 비만의 유발 원인 중의 하나로 알려진 고지혈증(hyperlipidemia)에 대한 예방효과가 있는 것으로 알려진 전통방식으로 제조된 고추장의 생리활성 기능성 효과를 분석하고자 하였다. 이 연구에서는 실험동물로서 Sprague-Dawley(SD)-Rat에 대해서 고추장 추출물의 건강증진 효과에 대해서 실험동물을 사용하여 직접 확인하고 시도하였다. 실험군은 실험동물용 일반사료만을 먹인 음성대조군 그룹(N-group)과 일반사료와 고추장 추출물을 동시에 먹인 시험그룹(K-group) 그리고 양성대조군으로 고콜레스테롤 사료만을 먹인 그룹(H-group)으로 구분하여 5주간 사육하면서 건강증진효과의 발현에 대해서 분석하 였다. 3그룹의 실험동물을 5주간의 사육 후 해부했을 때 H-group의 모든 동물(100%)에서 공통적으로 심한 지방간 (fatty liver) 소견이 관찰되었으나, N-group이나 K-group의 어떠한 동물에서도 지방간 소견은 관찰되지 않았다. 한편, 실험동물의 혈장성분에 대한 혈액생화학적 성적의 비교에서는 고지혈증의 예방에 유익한 성분으로 알려진 HDL의 경우, 고추장 추출물 투여 그룹(25±8.43 ㎎/㎗)은 H-group(22.6±4.16) 보다 다소간 상승된 수치를 보였으나, 특히 고지혈 증을 악화시키는 원인으로 알려진 LDL 경우에는 H-group (55.8± 44.8 ㎎/㎗)이 고추장 추출물 투여 그룹(8.6±1.52 ㎎/㎗)과 음성대조군인 N-group(9.8±2.39)의 성적보다도 유의적으로 높은 수치를 나타냈다. 결과적으로 이 연구에서 SD-Rat에 투여했던 고추장 추출물은 실험동물에서 건강기능 개선효과의 하나인 저지방혈증 효과를 발현한 것으로 사료되었다.

본 연구는 ICR-mouse를 실험군당 5마리를 공시하여 식이에 산벚나무 씨앗 기름 및 옥수수 기름을 첨가하여 배합한 사료의 섭취가 쥐의 혈중 지질 수준에 미치는 영향을 비교․ 분석하였다. 1. 산벚나무 씨앗에는 palmitic acid, oleic acid 및 linoleic acid 등이 함유되어 있으며, linolenic acid와 erucic acid가 소량 함유되어 있다. 2. 산벚나무 씨앗 기름의 항산화 값(DPPH)은 4.63%로 나 타났으며, 신장의 무게는 다른 두 군에 비해 산벚나무 씨앗 기름을 섭취한 군(1.24±0.22 g)에서 유의적으로 높았다(p<0.05). 3. 산벚나무 씨앗 기름을 섭취한 군에서 HDL-cholesterol 농 도는 가장 높았으며, 혈중 LDL-cholesterol 농도는 가장 낮았 다(p<0.05). 이상의 결과를 정리해 보면, 산벚나무의 씨앗 기름의 지방 산 조성은 다른 식물성 씨앗 등의 지방산 조성과 큰 차이가 없었으며, 혈중의 HDL-cholesterol 농도를 높여주는 반면에, LDL-cholesterol 농도는 낮추어 주는 것으로 나타났다. 따라서 산벚나무의 씨앗 기름을 현재 유지 자원으로 사용되고 있는 참깨나 들깨와 같이 식용유지 자원으로 개발하기 위해서는 Choi 등(2012)의 연구에서 지적했듯이 씨앗 기름의 항산화 효과, 산패 진행 정도 및 인체에 미치는 영향 등의 지속적인 연구가 이루어져야 한다고 사료된다.

This study was conducted to investigate the anthropometric data, nutrient intakes and serum profiles in premenopausal and postmenopausal women living in Gyeonggi-do Province, Republic of Korea. The subjects were 49 premenopausal women and 63 postmenopausal women who are not taking any hormone or cardiovascular drugs. Anthropometric measurements were taken by a trained practitioner and the data for dietary intakes were obtained by a 24-hour recall method. Serum samples were collected and analyzed for the total cholesterol, triglyceride (TG) and lipoprotein fractions. The mean age of the premenopausal women was 45.17±3.28 years and that of the postmenopausal women was 62.52±4.14 years. The height and weight were 157.86±4.35 ㎝, 58.75±6.01 ㎏ in premenopausal women and 156.42±3.62 ㎝, 57.63±5.38 ㎏ in postmenopausal women, respectively. WHR (waist hip ratio) in postmenopausal women was significantly higher than that of premenopausal women (p<0.05). There were no differences between the pre-and postmenopausal women in the intakes of energy, protein, fat, Ca, Fe, vitamin A, vitamin B1, vitamin B2, niacin, vitamin C and vitamin E. However carbohydrate and Na intakes in postmenopausal women were significantly higher than those of premenopausal women. In postmenopausal women, Ca intake was below and Na intake was extremely high considering KDRIs (Dietary Reference Intakes for Koreans). Serum triglyceride in postmenopausal women was positively correlated with age, BMI (body mass index) and WHR. Serum total cholesterol and triglyceride in postmenopausal women showed significantly negative correlations with fiber intake. These results suggest that it is necessary to help postmenopausal women maintain a healthy body weight. Postmenopausal women needs to increase Ca (calcium) intakes and diet quality by decreasing the intakes of Na (sodium). In addition, an adequate intakes of fiber is recommended for postmenopausal women to prevent cardiovascular disease.

본 연구의 목적은 여성 지체장애인을 대상으로 24주간 규칙적인 휠체어댄스 프로그램 참여가 혈중지질 및 심리적 웰빙에 어떠한 영향을 미치는지를 규명하여 여성 지체장애인의 생리적, 심 리적 효과에 대한 지표를 제시하는데 그 목적이 있다. 연구대상은 A시에 거주하는 B장애인복지 센터 회원들 중 전혀 운동 경험이 없는 40세 이상의 여성 지체장애인 총 20명을 대상으로 실험 집단 10명(지체기능장애 8명, 관절장애 2명)과 통제집단 10명(지체기능장애 7명, 관절장애 3명)으 로 무작위로 할당되어 구성하였다. 측정된 자료는 IBM SPSS Statistics 19.0 통계프로그램을 이용 하여 실험집단과 통제집단 간의 평균과 표준편차를 종속변인별로 구하였다. 두 집단 간의 평균 비교는 사전검사 측정값을 공변인으로 하여 사후검사 측정값을 서로 비교하는 공분산분석 (Analysis of Convariance)으로 분석하였으며, 통계적 유의수준은 .05로 설정하였다. 연구결과, 첫 째, 휠체어댄스 프로그램 참여는 여성 지체장애인의 혈중지질의 총 콜레스테롤과 중성지방은 감 소시켰으며, 고밀도 지단백콜레스테롤은 증가시켰다. 둘째, 휠체어댄스 프로그램 참여는 여성 지체장애인의 심리적 웰빙의 즐거움, 유능감, 자아실현, 몰입감에 긍정적 영향을 미쳤다. 따라서 24주간의 휠체어댄스 프로그램은 여성 지체장애인들의 신체활동의 감소와 장애로 인해 저하된 생리적 변화의 개선뿐만 아니라, 특히 심리적요인인 심리적 웰빙에 매우 긍정적인 결과를 가져 온다는 결론을 얻었다.

In this study, the effects of intake of Acer mono Max. seed oil, and Magnolia denudata seed oil on the lipid levels of mouse blood were compared to those of commercially available vegetable oils. FiveICR mice were each fed a corn oil, Acer mono Max. seed oil, and Magnolia denudata seed oil supplemented diet for a total of 8 weeks. The serum profiles of mice fed Acer mono Max. seed oil and Magnolia denudata seed oil were high in palmitic acid, oleic acid, and linoleic acid. The saturated fatty acid contents of mice fed Acer mono Max. seed oil and Magnolia denudata seed oil were 3.95% and 0.88%, whereas the unsaturated fatty acid contents were 8.71% and 4.60%, respectively. The liver and spleen weights of mice fed Acer mono Max. seed oil were higher than those fed corn oil (p<0.05). Total cholesterol level was highest in mice fed Acer mono Max. seed oil (p<0.05), whereas there were no significant changes in the cholesterol levels of mice fed Magnolia denudata seed oil and corn oil. The HDL-cholesterol levels in mice fed Acer mono Max. seed oil (175.80±27.66 ㎎/㎗) and in those fed Magnolia denudata seed oil (145.20±19.10 ㎎/㎗) were higher compared to those of mice fed corn oil (p<0.05). In conclusion, there were no significant differences in fatty acid composition between mice fed Acer mono Max. seed oil and Magnolia denudata seed oil. Future study on the antioxidant effects of seed oils should be carried out.

This study was performed to examine the relationship between the body mass index (BMI), the body fat, and the serum lipids of post-menopausal women in rural areas. The subjects were 510 women aged 50 and over. As a result of this study, we found a trend of decreasing BMI as age increased, but body fat increased. In addition, there was a significant decreasing of the lean body mass than an increasing of the body mass index according to increasing age. Therefore, this study confirmed that a main cause of rural women being classified as obese is a decrease in lean body mass, rather than an increase in of body fat. Of all subjects, 36.3% (18.5≤BMI 〈 23) of all subjects were classified as having normal BMI, whereas only 21.4% were classified as having normal body fat. Out of 190 subjects who were body fat 30% and over, 38 subjects were classified as obese (BMI≥25) and 113 subjects were classified as overweight (23≤BMI 〈 25). The percentile of those with a BMI of 25kg/m2 was 70, and they had 30.82% body fat. HDL cholesterol showed a negative correlation with anthropometric factors (height, weight, body mass index, waist circumference, waist hip ratio, body fat), and total cholesterol, LDL cholesterol, and triglycerides showed a positive correlation. Especially, total cholesterol, LDL cholesterol, and hip circumference showed significant correlations. Because of differences in the body fat and lean body mass by age group, it seems difficult to assess obesity via BMI only. The elderly especially should have a higher significance placed on body fat or abdominal fat than only BMI.

Numerous studies have suggested that dietary flavonoids contribute to prevent cardiovascular disease. Onion contains many functional phytochemicals such as quercetin. The aim of this study was to examine whether onion peel extracts supplementation affect blood lipid profiles and blood coagulation in animal model. Total 48 Sprague-Dawley male rats at 5 weeks old were divided into 6 groups with different diets(C: control, HF: high fat diet, HFOE 0.01%: high fat+onion peel extract 0.01% diet, HFOE 0.02%, HFOE 0.05%, HFOE 0.1%) for 8 weeks. Onion peel extract supplementation significantly decreased serum levels of LDL-cholesterol and increased HDL-cholesterol, while total cholesterol and triglyceride levels were not affected. Hematological parameters(hematocrit, white blood cell, red blood cell, and platelet count) and blood coagulation parameters(prothrombin time, activated partial thromboplastin time, thrombin time, and fibrinogen) were not significantly different among 6 groups. However, activated partial thromboplastin time of HFOE 0.05% group was significantly longer than that of HF group. These results indicate that onion peel extract supplementation displays hypocholestrolemic effects but does not seem to have anti-coagulation effects in high fat fed SD rats.

This study demonstrated the effects of extracts from the mushroom Keumsa sangwhang(Phellinus linteus) (KPLE) on fasting glucose and cholesterol levels in human blood. In this double-blind, placebo-controlled human intervention study, healthy volunteers were randomized to receive 3.3 g of KPLE (n=31) or placebo (n=31) per day by oral administration for 8 weeks. The cholesterol and fasting serum glucose levels were evaluated before and after treatment. The fasting serum glucose level was significantly decreased by KPLE administration (p<0.01), but the total cholesterol, triglyceride, HDLcholesterol and LDL-cholesterol concentrations did not change. This study suggests a possibility that KPLE may be useful as a functional food for the prevention of diabetes mellitus.

This study was conducted to examine the correlation among meals variety, obesity index, blood pressure, and lipid profiles of Korean adults. A total of 308 adults(men 124, women 184) measured the anthropometric characteristics, blood pressure, dietary intake using 24-hour recall method, and serum lipid profile. The average ages of the study subjects were 50.9 yrs in men and 51.4 yrs in women. The average height, weight and BMI were 166.3 cm, 68.4 kg, 24.7 kg/cm2 in men and 154.3 cm, 59.8 kg, 25.0 kg/cm2 in women, respectively. The numbers of food items in meal of men and women were 14.1, 15.9 for breakfast, 15.7, 15.9 for lunch, 14.7, 14.1 for dinner, respectively. The numbers of dish items in meal of men and women were 4.0, 4.3 for breakfast, 4.3, 4.3 for lunch, 4.2, 3.9 for dinner, respectively. The average blood pressure, total cholesterol, triglyceride, HDL-cholesterol, LDL-cholesterol and atherogenic index were 126.6/76.0 mmHg, 181.0 mg/dL, 157.7 mg/dL, 40.9 mg/dL, 108.6 mg/dL, 3.5 in men and 123.2/73.6 mmHg, 185.0 mg/dL, 137.3 mg/dL, 44.8 mg/dL, 112.7 mg/dL, 3.2 in women, respectively. The total cholesterol was negatively correlated to the number of food item for lunch(p〈0.05). Therefore, more systematic studies to investigate the meal variety roles of blood lipids in meals of adults were required.
