Physicochemical and microbiological properties of red beans, soybeans, barleys, and corns irradiated by gamma-ray at 1.2 kGy, 10.1 kGy, or 30.5 kGy were investigated. Moisture content and crude lipid content of the irradiated cereals showed no significant difference from the nonirradiated group, TBA values of corns irradiated at 30.5 kGy increased. Gamma irradiation reduced the numbers of mesophilic and psychrotrophic bacteria in the cereals. Yeasts and molds were reduced below detection levels even at 1.2 kGy dose-irradiation. There was no significant difference in reducing sugars between the irradiated cereals and the nonirradiated ones except corns. Stachyose, raffinose, and sucrose of soy beans and sucrose of barleys increased by 30.5 kGy dose-irradiation. Loss of riboflavin content of the irradiated samples was not observed except red beans irradiated at 30.5 kGy. In Hunter's color, b value of the red bean powder increased but L value of the soybean powder decreased by the irradiation. L, a, and b values of the barley powder slightly increased under 30.5 kGy dose-irradiation and b value of the corn powder decreased under 10.1 or 30.5 kGy-dose irradiation.

One hundred sixty housemakers and restaurant managers were questioned on the state of consumption and attitude of the agricultural products imported from the foreign countries. The data in the present study indicated that : 1) although 87.7% of the housemakers and 79.2% of the restaurant managers have an objection to an import of foreign agricultural products, if the quality of the foreign products are similar to that of the domestic ones, they prefer to those with the lower price, and the restaurant managers are more concerned about the price than the housemakers do ; 2) only 36% of the housemakers and 22.5% of the restaurant managers confirm the place of origin or manufacture of the foreign arricultural products when they purchases them ; 3) about 41.4% of the housemakers and 60.7% of the restaurant managers have been consuming the chinese agricultural products primarily because of the lower price ; 4) the most frequantly consummed chinese food products by the housemakers are vegetables followed by cereals and grains, seeds, seafoods, and spices, whereas the restaurant managers prefer seafoods to seeds.

충분한 단백질과 최소한의 단백질을 공급받은 쥐의 성장과 무기질 분포에 있어서 zine와 VitaminB-6 간의 상호관계

손숙미 카톨릭대학교생활과학연구소 1988 생활과학연구논집 Vol.8 No.1

Young male rats were fed 7.5% and 5% protein provided by dried egg white solids supplemented with zinc (0.50, or 100ppm) and/or Vitamin B-6(1, 5 or 100ppm) for four weeks. All animals receiving the non-zinc supplemented diets exhibited poor growth, while 50ppm of zinc supplement resulted in marked improvement in weight gain. Increases in weight gains associated with adquate protein (15%) ocurcred only when the diet contained at least 50ppm of zinc, while increases in growth associated with vitamin B-6 supplements occurred only when the protein was marginal (7.5%). Increases in dietary zinc were associated with decreases in liver zinc deposition. Increases in dietary vitamin B-6 resulted in increased liver copper and zinc levevels, but had no apparent effect on liver iron deposition. The results suggest a zinc-vitamin B-6 interaction which has an influence on the apparent utilization dietary protein and on copper and zinc status in young rats.

손숙미,신현경 가톨릭대학교 생활과학연구소 1995 생활과학연구논집 Vol.15 No.1

This study determined plasma glucose, free fatty acid (FFA), cortisol, creatine phosphokinase (CPK), calcium (Ca), magnesium (Mg), sodium (Na), potassium (K), and Ca and Mg in heart muscle and femur. 66 Sprague-Dawley male rats were devided into two diet groups : adequate Mg group (0.05% Mg), marginal Mg group (0.005% Mg). After the rats were on experimental diets for 5weeks, rats for each group were randomly assigned to no stress, stress stress+recovery group and 2hours of IMMB stress were administered to stress and stress+recovery group. Rats of stress group were decapitated shortly after the IMMB stress and rats of stress+recovery group were decapitated after 2hours of recovery. The following were found. 1) Plasma cortisol and CPK were significantly increased in group with stress and group with stress+recovery respectively regardless of Mg content in diet. 2) Plasma glucose and FFA and Ca in plasma, femur and cardiac muscle were not significantly different among groups. 3) Plasma Mg were siginificantly increased with stress only in rats fed marginal Mg.

부천시 노인들의 영양상태 및 이에 영향을 미치는 인자에 관한 연구 : II. Related factors affecting to the nutritional status of elderly II.부천시 노인들의 영양상태에 영향을 미치는 인자에 관한 연구

손숙미 가톨릭대학교 생활과학연구소 1999 생활과학연구논집 Vol.19 No.1

This study was performed to investigate the difference of antropormetric and biochemical data according to the factors like food habit, drinking, smoking and exercise. The subjects were 310 elderly aged over 65, apparently healthy and residing in Puchon city. Male elderly with BMI higher than 24 showed 141.9mmHg of systolic blood pressure, which was significanatly higher than 123.7mmHg of elderly with BMI less than 20. Fasting blood glucose, 166.1mg/dl in male elderly with BMI higher than 27, was significantly higher than those of other groups. Female elderly with BMI above 27 showed significantly increased (SGPT and serum triglyceride. Elderly preferring meat showed significantly increased) serum cholesterol (236.4mg/dl) than those relishing both meat and vegetable. Elderly having meat 2∼3 times a week showed significantly higer HDL-C ; total cholesterol ratio and lower CHD index than those of elderly having meat less than one time a week. Elderly drinking one or two times a week showed significantly higher hemoglobin and fasting blood glucose. Mean BMI of smokers was significatnly lower than nonesmokers and exsmokers Elderly exercising more than 2 hours showed higher hemoglobin and lower serum cholesterol.

casein과 대두단백질을 공급받은 흰쥐에 있어서 식이내 zine및 copper수준이 형장내 cholesterol 대사와 mineral의 조직분포에 미치는 영향

손숙미,김선희 聖心女子大學校 1989 論文集 Vol.21 No.-

This study was performed to investigate the effect of supplementary zine /910,30,120,ppms) and Cu(0,3,6 ppms) levels in the diet upon plasma cholesterol level and tissue distribution of minerals in rats fed casein and soyprotein isolate during six weeks after weanling. The results obtained are summarized as following. 1) plasma tolal cholesterol was increased with increasing supplementary Zn but the increased was not significant. Excess zn supplementation(120/3) was associated with highest level of plasma total cholesterol, whereas marginal Zn supplement(10/0) was associated with lowest level of plasma total cholesterol. Plasma total cholesterollevel did not appear to be affected by supplementary Cu level used in this experiments(0,3,6 ppms). 2) HDL-cholesterol, HDL₃-cholesterol level tended to be highter with increasing supplementary Zn level in both casein and soyprotein groups but the increase was not significant. In soyprotein group, significantly higher DDL₂-cholesterol level showed in rats fed excess Zn and marginal Cu(120/3) suggested increase in plasma total cholesterol level in 120/3 group was partly due do the increase in HDL₂-cholesterollevel. Atherosclerosis indicator(plasma total cholesterol/HDL cholesterol)in 120/3 group was not significantly different from that of controls (30/6) regardless of protein source. 3) The levels of total cholesterol per gram of liver were seemed to be affected by supplemtary 쳐 levels regardless of protein source. The high contents of total cholesterol in rats fed deficient Cu(10/0,30/0 groups) were partly associated with reduced clearance of cholesterol from the liver to the plasma pool and reduced excretion of cholesterol into feces. 4) The amounts of total cholesterol excreted in feces per day were significantly corre lated with liver Zn/Cu ration(r=0.81, p,<0.01). High Zn/Cu ratio was associated with high total cholesterol excreted in feces per day. 5) Plasma and liver Zn were independent of dietary zn level, wheras plasma and liver cu were more representative of dietary Cu.

The Effect of Milk Supplementation on Bone Density and Iron Status of Elderly

Son, Sook-Mee,Chon, Yeh-Na Korean Society of Community Nutrition 1998 대한지역사회영양학회지 Vol.3 No.5

This study was performed to investigate how milk supplementation can benefit the elderly by increasing bone density but possibly harming the iron status concomitantly. Forty one elderly subjects over 65 years of age(male : 9, female : 32) participated. All subjects were apparently healthy, home staying and attending meal service for lunch at the welfare center. They were from low income area of Puchon city. One cup of milk per day was served for 10 months. The mean intake of calcium was significantly increased for females after milk supplementation. Males showed significantly increased means of triceps skinfold thickness, suprailiac skinfold thickness and waist circumference. Females showed significantly increased measurements fo three kinds of skinfold thickness, waist circumference, and hip circumference. There were no significant change in the mean bone density of lumbar spine$(L_2~L_4)$, femoral neck, ward's triangle and torchanter, but the proportion of osteopenia estimated by the T score of lumbar spine bone density was lowered from 50.0% to 34.6% for females. The mean Hb level was significantly for males. The proportion of anemia estimated by Hb(<12g/dl), Hct(<36%) and serum ferritin(<15mg/ml) were increased from 17.2% to 51.7%, from 20.7% to 44.8% and from 10.3% to 17.2%, respectively for females. It looks like milk supplementation can effect the intakes of several nutrients considered to be commonly deficient in the Korean diet fo elderly people, increase some anthropometric measurements, and decrease the proportion of osteopenia. However it can have adverse effects on iron status of females.

The Effect of an Energy Restriction Program on the Weight Loss and the Change of Biochemical nutritional Status in Obese Women

Son, Sook-Mee,Kim, Hee-Jun,Lee, Yoon-Na,Lee, Hong-Sup Korean Society of Community Nutrition 1997 대한지역사회영양학회지 Vol.2 No.5

This study was conducted to investigate the effect of an energy restriction program on the weight loss and changes of the biochemical nutritional status for 35 obese women. The energy restriction program took place over a 3-week period that was devided into two parts. The first part consisted of 750-800kcal diet and the second part of 800-1000kcal. Subjects were provided a low energy formula and a menu for the recommended diet. Anthropometric and biochemical measurement before and after the energy restriction program were estimated. Mean weight loss was 3.0kg, accordingly the obestiy rate was lowered from 40.2 to 34.4, BMI from 29.2 to 28.9 and fat weight from 23.3kg to 21.0kg( <0.01. <0.05). Waist circumference loss was most prominent(4.4%) compared to triceps(21% loss)and hip circumference(2.2%loss). Mean RBC count, hemoglobin and hematocrit were significantly lowered( <0.01) but they were in the normal range. Systolic blood pressure was significantly decreased from 124.1mmHg to 113.1mmHg . Mean SGOT and SGPT were lowered from 29.3u/L to 20.0u/L and from 28.7u/L to 16.6u/L, respectively. It seems that the 3 weeks of energy restriction program used in this study was effective in improving anthropometric measurements without producing deficiency of iron or other susceptible nutrients.(Korean J community Nutrition 2(5) : 695-700,1997)

Sook Mee, Son,Shin A, Nam-Gung,Se Hee, Han The Korean Society of Community Nutrition 2004 Journal of community nutrition Vol.6 No.2

This study was performed to investigate the nutritional status associated with alcohol consumption in Korean adults men and women. The data was derived from the 2001 Korean National Health and Nutrition Survey. The number of subjects included were 6090 (Men: 2789, Women: 3031) aged 20 (equation omitted) < 65y. Men consuming moderate alcohol ((equation omitted) 24 g/day but < 48g/day) had higher intakes of energy and vitamin B groups than the ones consuming less than 24g/day. Heavy drinking men reporting more than 48g alcohol/day were observed as having 3207.2kcal of energy intake (130% of Korean RDA) and significantly elevated levels in most of the nutrients. For women drinkers, when the alcohol consumption was moderate ((equation omitted) 12g/day but 24g/day) or heavy((equation omitted) 36g/day) the energy intake was 2188.9kcal(100% of RDA) or 2627.5kcal (130% of RDA). The other nutrients protein, fat, calcium, iron and vitamin B group were also higher in women with heavy alcohol consumption. Heavy drinking women showed significantly higher weight, BMI and HDL-C. In contrast, heavy drinking men did not show any significant difference in BMI but showed significantly elevated blood pressure, HDL-C and lower serum cholesterol.
