  • This study was performed to investigate the effects of liquid culture of Agaricus blazei on the lipid metabolism and enzyme activities in growing male rats. Sprague-Dawley rats were given four different types of diets for a succeeding period of 5 weeks, respectively: a normal diet group (7% corn oil), a high fat diet group (7% com oil + 15% lard), a 20 or 30% Agaricus diet groups (high fat diet + 20 or 30% Agaricus in water) according to the levels of Agaricus supplementation. The body weight gains, food intake, food efficiency ratios, and hepatic, kidney, spleen and pancreas weights of the rats fed 20 or 30% Agaricus diets were similar to those of the rats fed high fat diet. The epididymal fat pad weight of the rats fed high fat diet and 20 or 30% Agaricus diets were significantly higher than that of the rats fed normal diet. The concentrations of serum triglyceride, total cholesterol, LDL-cholesterol and HDL-cholesterol, and the activity of glutamic pyruvic transaminase in the rats fed 30% Agaricus diet were significantly lower than those in the rats 114 high fat diet. But the concentrations of hepatic total cholesterol and triglyceride of rats fed the 20 or 30% Agaricus diets were similar to those of rats fed the high fat diet. The HDL-oholesterol/total-cholesterol ratio of the rat fed 30% Agaricus diet was significantly higher than that of the rats fed high fat diet, The activity of glutamic oxaloacetic transaminase in the rats fed 20 or 30% Agaricus diets were similar to those in the rats fed high fat diet. There were no differences in the concentrations of total protein, hemoglobin and glucose, and the activities of alkaline phosphatase, and the atherogenic index in the serum among the experimental groups. These results showed that the 30% Agaricus diet feeding decreased the total cholesterol, the triglyceride and the LDL-cholesterol, and increased the HDL-oholesterol/total cholesterol ratio in serum of rats.

The mean height was 162cm and weight was 52.3Kg. 26.9% of the subjects responded that they had experienced the unbalanced diet, 56% the irregular meal, 39.6%intermittent dizziness, and 63.4% the premenstrual syndrome. 53.7% had feeling that skin temperature of their four extremities was 'a little lower than others'. The mean BMI(Body Mass Index) was 19.8, 'normal level' was 41.8%. 18.7% responded that their characters were 'introspective ones'. The mean age of menache was 13.8 years old. The subjects responded that the mean number of pads they used per day during menstrual periods was 4.6 sheets. The mean duration of menstruation was 5.4 days, 10.4% responded that their menstrual cycles were 'extremely regular', 44.8% was 'regular', 36.6% was 'a little irregular', and 8.2% was 'extremely irregular'. Out of them who had experienced the dysmenorrhea, 21.3% had family history of dysmenorrhea in connection with their mother and 35.0% in their sisters. The mean of the first time that they experienced dysmenorrhea was 15 years old. 94% of the subjects responded that they had experienced the dysmeorrhea. 47.6% of the subjects responded that they experienced the dysmenorrhea 'monthly' and 52.4% 'intermittently'. 53.0% of them who had experienced dysmenorrhea responded that dysmenorrhea was the severest 'on the first menstrual day' and 22.4% 'on the second day'. 48.8% of them who had experienced dysmenorrhea responded that the most painful region was 'low abdomen'. 40% of them who had experienced dysmenorrhea responded that they used 'analgesics' to soothe dysmenorrhea, 24.8% used nothing, 18.4% lay in their beds or slept, and 12% made their 'low abdomen' warm. 70.3% who had used analgesics because of dysmenorrhea took analgesics 'one or two times per month', 25.7% 'intermittently', and 4.0% more than 3 times per month. The analgesics which they used were 'geworin(33.8%),' 'penzal(32.4%)', 'tyrenol(18.9%)', and 'aspirin(4.2%)'. (47.9%) of them who took analgesics because of dysmenorrhea responded that the duration of analgesics effect was '4 to 8 hours'. 15.1% of them who experienced dysmenorrhea responded that they had visited the hospital. 2) The incidence of premenstrual syndrome was no significant difference according to the BMI, unbalanced diet, pattern of meal, skin temperature of four extremites, and characters. 3) The incidence of dysmenorrhea was significant difference according to the BMI, unbalanced diet, pattern of meal, skin temperature of four extremites, and characters. 4) The incidence of analgesics usage was significant difference according to the BMI, subjects with low BMI took more analgesics than those with normal BMI (p<.05). The incidence of analgesics usage was significant difference in accordance with pattern of meal. The women who had a meal regularly took more analgesics than those who had a meal irregularly(p<.05). But the incidence of analgesics usage was no significant difference in accordance with the unbalanced diet, characters, the incidence of dizziness, skin temperature of four extremities, the incidence of premenstrual syndrome.

  • Purpose: The purpose of this study was to investigate the effects of nutrient intake and dietary diversity score (DDS) on osteoporosis after controlling for sex, age, socioeconomic level, drinking, smoking, physical activity, and body mass index (BMI) as mediators using the 2015-2017 Korean National Health and Nutrition Examination Survey (KNHANES) data. Methods: This study was focused on the age group of 50s and older by using the 2015-2017 KNHANES data. Subjects diagnosed with osteoporosis were classified as the osteoporosis group, and the other subjects were classified as the normal group. Logistic regression was used to assess the association between nutrient intake and DDS after controlling for mediators. Results: The risk of osteoporosis was 2.38 times lower in the 50-65 age group than in the 75 years and older group. The mediators affecting the incidence of osteoporosis by age group were sex, age, household income level, and education level in the 50-64 age group; sex, education level, drinking, and BMI in the 65-74 age group; and sex, age, current smoking, drinking, BMI, and energy intake in the 75 years and older group. The effect of nutrient intake on osteoporosis, with the exception of vitamin B1, was fully mediated by these mediators. The effect of vitamin B1 was partially mediated by mediators in the age group of 65-74 years, and vitamin B1 was effective for preventing the risk of osteoporosis by 25% when consumed over EAR. The effect of DDS was partially mediated in the age group of 75 years and older, and DDS of 2 or less increased the risk of osteoporosis by 2.59 times. Conclusion: As a result of this study, it is necessary to recommend the balanced intake of various foods including grains, meat·fish·legumes, vegetables, fruits, and dairy products as dietary guidelines for the prevention of osteoporosis and promotion of bone health in the elderly.

  • Purpose : Diabetes mellitus is a major risk factor for the development of cardiovascular disease. Early atherosclerotic changes in the arterial walls begin in adolescence and the risk factors are associated with its development. To assess the usefulness of carotid artery intima-media thickness (IMT), as a marker of early atherosclerosis, we evaluated the structural and functional characteristics of the carotid artery and investigated their relationshop with the metabolic and anthropometric parameters in children and adolescents with type 1 diabetes. Methods : For this study, we enrolled 23 children with type 1 diabet and 19 age and sex-equivalent healthy children as the control group. Metabolic and anthropometric parameters such as serum lipid levels, plasma glycated hemoglobin (HbA1c), and body mass index were measured after a 12-h fasting period. The carotid artery IMT was measured by a high-quality ultrasound system, and compliance, and distensibility were calculated by an equation. Results : There were no significant differences between the 2 groups with regard to the sex ratio, age, blood pressure and serum cholesterol levels' however, HbA1c levels were significantly higher in the diabetic children (8.5±1.8 vs. 5.0±0.2, P=0.001). Ultrasonographic findings showed that compared with the control group, the diabetic group had higher IMT (0.45±0.06mm vs. 0.41±0.04mm, P=0.04), but there were no significant differences in compliance and distensibility. The HbA1c (P=0.002) and high-density lipoprotein cholesterol (P=0.026) levels were independent IMT predictors in the diabetic group. Conclusion : Here, the carotid artery IMT was higher in the diabetic group, and it is correlated with atherosclerotic risk factor. Thus, carotid IMT could be evaluated as a marker of early atherosclerosis in diabetic children.

  • The objective of the present study was to perform a comparative analysis of the chemical properties of the cultivation site soil and growth characteristics of organically and conventionally cultivated ginseng (Panax ginseng C. A. Meyer). Organically and conventionally cultivated ginseng samples (4-, 5-, and 6-year-old) were collected from 52 fields at 14 locations throughout Korea. The samples were collected over three years from 2013 to 2015, with the collection period between October and November of each year. In order to increase the yield of organically cultivated ginseng, the amount of nutrients was increased to match that of the conventional cultivation system, which highlights the need for proper management in accordance with the standards for chemical properties of soil. Growth duration of organic ginseng was 60days shorter than that of conventional ginseng and its average yield per 1ha was 60% than that of conventional ginseng. Root weight of organically cultivated ginseng was approximately 54% that of conventionally cultivated ginseng. Rhizome diameter and body shape index of organically cultivated ginseng were lower than those of conventionally cultivated ginseng, indicating that organically cultivated ginseng was thinner and longer than conventionally cultivated ginseng. Root length was greater in 5-year-old conventionally cultivated ginseng with a low percentage of paddy-upland rotation fields. The number of rootlets was lower in 5- and 6-year-old organically cultivated ginseng with a high percentage of direct seeding cultivation. Dry weight was distinctly lower in 5- and 6-year-old organically cultivated ginseng with early defoliation than that of conventionally cultivated ginseng. Incidences of notched belly and root rot tended to be higher in conventional cultivation, with the incidence of notched belly being distinctly higher in 4- and 6-year-old roots and root rot being more prevalent in 5- and 6-year-old roots. Red discoloration and eelworm damage, which are highly affected by soil moisture, were most common in the organically cultivated 4-year-old roots. Organically cultivated ginseng showed early defoliation than conventionally cultivated ginseng, as a result, its yield and weight were low, while the incidence of physiological disorders was low. In order to increase the yield of organically cultivated ginseng, studies on cultivation technology that can overcome early defoliation, as well as soil moisture management that can minimize physiological disorders, are required.

  • The objective of this study was to determine the effect of sakso 2 corn kernels and cobs extracts on antioxidant activity in rats fed a high fat-cholesterol diet (HFC) for 2 weeks. 48 male Sprague-Dawley (4-weeks-old) were randomly divided into 6 groups: normal diet (N), HFC (C), HFC and 0.05% kernel extracts of Saekso 2 (T1), HFC and 0.25% kernel extracts of Saekso 2 (T2), HFC and 0.05% cob extracts of Saekso 2 (T3), HFC and 0.25% cob extracts of Saekso 2 (T4). The weight gain in all treatment groups were significantly lower and the food efficiency ratio (FER) in all treatment groups except T3 were lower than C group. Liver index (liver weight/100 g body weight) in N group and T2 were significantly lower than C group. The level of total cholesterol in plasma of N group and T2 were significantly lower than C group and HDL-cholesterol in plasma of N group and T2 were significantly lower than C group. Malondialdehyde (MDA) concentration of thiobarbituric acid reactive substances in N group, T3 and T4 were significantly lower than C group. Activity of catalase (CAT) in all treatment groups were lower than C group. These result suggest that saekso 2 corn kernels and cobs extracts may reduce oxidative damage through the activation of antioxidative defense systems in rats fed high fat-cholesterol diets.

  • Purpose : Adiponectin, adipose tissue-specific protein, has anti-inflammatory and anti-atherogenic properties. It has been found to have a negative correlation with obesity and to play a role in modulating glucose tolerance and insulin sensitivity. Serum adiponectin concentrations are decreased in adults with obesity and type 2 diabetes. We investigated the difference in adiponectin levels between obese and non-obese children, and evaluated the relationship of serum adiponectin with body mass index(BMI), serum fasting insulin, lipid profiles and homeostasis model assessment(HOMA) in children. Methods : We measured serum adiponectin levels by radioimmunoassay in 113 children(82 obese children and 31 non-obese controls) from 8 to 15 years of age, and also checked BMI, fasting serum glucose, insulin and lipid profiles. Fasting and postprandial serum adiponectin concentrations were compared by oral glucose tolerance tests in 27 obese children. The correlations of adiponectin with BMI, insulin, low density lipoprotein(LDL)-cholesterol and HOMA were analyzed by Pearson's correlation. Results : The serum adiponectin levels were significantly lower in the obese group(19.7 mg/mL) than in the non-obese group(27.5 mg/mL)(P<0.01). Serum adiponectin concentrations were negatively correlated with BMI(r=-0.39, P<0.01), serum insulin(r=-0.28, P<0.01), LDL-C(r=-0.20, P<0.01) and HOMA(r=-0.22, P<0.01). At oral glucose tolerance tests in obese children, postprandial 2 hours adiponectin level(19.8 mg/mL) was decreased compared to fasting level(25.8 mg/mL)(P<0.01). Conclusion : Serum adiponectin concentrations were inversely related to adiposity and insulin resistance in children. We suggest the serum adiponectin level could be used as an early marker of insulin resistance in obese children.

  • An investigation was carried out to study the effect of two housing systems on feed intake and nutrient utilization of sheep in a semi-arid region of India. Two types of housing managements were adopted. The first was a shed- 20'×10' structure with all the four sides of 6' chain link fencing with central height of 10'. The roof was covered with asbestos sheets, with mud floorings. The second was an open corral- 20'×10' open space with all the four sides covered with 6' chain link fencing. Thirty-four (32 ewes and 2 rams) sheep were grazed together on a 35 ha plot of native range. All the sheep were grazed as a flock from 08:00 to 17:00 h during the yearlong study. The flock was divided into two groups (16 ewes+1 ram) in the evening and housed according to two housing systems (Shed and Open Corral). Three digestion trials were conducted during three defined seasons of monsoon, winter and summer seasons to determine the effect of housing on nutrient intake and utilization. Blood samples were collected in three seasons for the estimation of hemoglobin and glucose. Dry and wet bulb temperatures were recorded at 06:00 A.M. and 09:00 P.M. using suitable thermometers both inside the shed and in the open corral and temperature humidity index (THI) was calculated. There was significant (p<0.05) difference in the THI between shed and open corral in all the seasons, indicating that the shed was always warmer compared to open corral. The daily dry matter intake (DMI, g/d) was 965, 615 and 982 in sheep housed under shed and 971, 625 and 1,001 in those housed in open corral during monsoon, winter and summer season, respectively. These differences were however non-significant (p>0.05). The digestibility of DM was 45.92, 45.13 and 50.30 in sheep housed under shed and 43.64, 45.02 and 55.02 in sheep housed in open corral during monsoon, winter and summer seasons, respectively. There was no significant (p>0.05) difference in the digestibility of nutrients in sheep maintained under shed and in open corral. Blood Hb concentration was 13.97, 14.13 and 13.15 in sheep housed under shed and 15.27, 13.63 and 14.82 in those kept in open corral, whereas blood glucose concentration was 59.67, 59.70 and 52.33 in sheep under shed and 61.00, 61.00 and 57.83 in open corral, during monsoon, winter and summer, respectively. There was also no significant effect of housing on the body weight changes, wool yield and survivability in ewes. Although housing had no significant effect on nutrient intake, their utilization and blood parameters, there was significant effect on the physiological responses and energy expenditure of sheep maintained under the two housing systems (Bhatta et al., 2004). It can be concluded from this study that the housing systems didn't have any significant effect on the nutrient intake and utilization of native breed like Malpura, which were well adapted to the hot semi-arid conditions of India. However, while deciding provisions for housing of different breeds of sheep (both crossbred and native) parameters like physiological responses, energy expenditure, health conditions and overall economics of the systems should be taken into consideration.

  • The efficiency of energy transfer by a population of the farmed pacific oyster, Crassostrea gigas was studied during culture period of 10 months July 1979-April 1980, in Geoje-Hansan Bay near Chungmu City. Energy use by the farmed oyster population was calculated from estimates of half-a-month unit age specific natural mortality rate and data on growth, gonad output, shell organic matter production and respiration. Total mortality during the culture period was estimated approximate 36% from data on survivor individual number per cluster. Growth may be dual consisted of a curved line during the first half culture period (July-November) and a linear line in the later half period (December-April). The first half growth was approximated by the von Bertalanffy growth model; shell height, SH=6.33(1e0.2421(t+0.54)), where t is age in half-a-month unit. In the later half growth period shell height was related to t by SH=4.44+0.14t. Dry meat weight (DW) was related to shell height by log $DW=-2.2907+2.589{\cdot}log\;SH,\;(2, and/or log $DW=-5.8153+7.208{\cdot}log\;SH,\;(5. Size specific gonad output (G) as calculated by condition index of before and after the spawning season, was related to shell height by G=0.0145+(3.95×103×SH2.9861). Shell organic matter production (SO) was related to shell height by log SO=3.1884+2.5271ogSH. Size and temperature specific respiration rate (R) as determined in biotron system with controlled temperature, was related to dry meat weight and temperature (T) by log R=(0.386T0.5381)+(0.64090.0083T)logDW. The energy used in metabolism was calculated from size, temperature specific respiration and data on body composition. The calorie contents of oyster meat were estimated by bomb calorimetry based on nitrogen correction. The assimilation efficiency of the oyster estimated directly by a insoluble crude silicate method gave 55.5%. From the information presently available by other workers, the assimilation efficiency ranges between 40%and70%. Twenty seven point four percent of the filtered food material expressed by energy value for oyster population was estimated to have been rejected as pseudofaeces : 17.2% was passed as faeces; 35.04% was respired and lost as heat; 0.38% was bounded up in shell organics; 2.74% was released as gonad output, 2.06% was fell as meat reducing by mortality. The remaining 15.28% was used as meat production. The net efficiency of energy transfer from assimilation to meat production (yield/assimilation) of a farm population of the oyster was estimated to be 28% during culture period July 1979-April 1980. The gross efficiency of energy transfer from ingestion to meat production (yield/food filtered) is probably between 11%and20%.

  • Purpose: The current study was conducted in order to identify health and nutritional status of Korean underweight women in their twenties by comparing with normal, overweight, and obese women. Methods: Data from the 2010~2012 Korea National Health and Nutrition Examination Survey were used in this study. Subjects were 897 women aged 20~29 years. Subjects were classified according to underweight, normal weight, overweight, and obese groups based on body mass index. Health status was assessed using data from the health questionnaire and examination. Nutritional status was assessed using data from 24-hour dietary recall and a food frequency questionnaire. Results: The underweight group had higher education and exercised less than the obese group. Means of blood chemistry and blood pressure of the underweight group did not differ from those of the normal weight group. Means of fasting glucose, insulin, lipid profiles, blood cell counts, and blood pressure in the underweight group were different from those of the overweight or obese group. Proportions of delivery, breast feeding, and irregular menstruation in the underweight group were lower compared with the other groups. Except retinol intake, means of nutrient intake did not differ among four groups. There were significant differences among four groups in the intakes of cereals and eggs and frequency of consumption of dairy products. Conclusion: The current findings showed that health and nutritional status of underweight women in their twenties did not differ from those of normal weight women. In particular, health status of underweight women in their twenties was better than that of obese women of the same ages. Further study on health and nutritional status of extremely underweight women is necessary.
