  • Interaction of dietary Magnesium, Calcium and Polyunsaturated fatty acid(vegetable oils)on 3-Hydroxy-3-Methylglutaryl Co-A reductase activity was studied for a period of 30 days using isocalories and isonitrogenous as a basal diet . The subject rabbits were divided into 18 feeding groups. The results are summarized as follows: 1. The ratio of ${\alpha}_1-lipoprotein$ par lipalbumin is 0.34 for control group, 0.38 the highest group fed 0.1 Mg(II) 10ml plus perilla oil and basal diet, the lowest 0.25 group fed 0.1M Mg(II) 5ml plus sesame oil and basal diet. 2. The ratio ratio of ${\alpha}_2-lipoprotein$ per lipalbumin is 0.64 for control group. 0.95 as the highest for the group fed 0.1M Ca(II) 15ml plus sesame oil and basal diet, 0.1M Ca(II) 5ml plus perilla oil and basal diet. 3. The ratio of ${\beta}-lipoprotein$ per lipalbumin is 0.71 for control group, the highest 0.81 for the groups fed 0.1M Mg(II) 10ml plus sesame oil and basal diet, the lowest 0.37 for the group fed 0.1M Mg(II) 15ml plus soybean oil and basal diet. 4. In serum triglyceride, control group was 129.5mg%, the highest 155.4mg% for the group fed 0.1M Ca(II) 5ml plus sesame oil and basal diet, the lowest 85.7mg% for the group fed 0.1M Mg(II) 10ml plus soybean oil and basal diet. 5. In serum cholesterol, control group was 96.7mg%, the highest 152.5mg% for the group fed 0.1M Ca(II) 10ml plus sesame oil and basal diet, the lowest 80.5mg% for the group fed 0.1M Mg(II) 15ml plus soybean oil and basal diet. 6. In case of HMG-CoA reductase activity, control group was 0.95, the highest 0.98 for the group fed 0.1M Ca(II) plus soybean oil and basal diet. 7. Interaction between metal(II) ions and polyunsaturated fatty acid(vegetable oil) are soybean oil>sesame oil>perilla oil, for Mg(II). soybean oil>perilla oil>sesame oil, for Ca(II). Therefore, it is invetigated that the interaction between metal ion and polyunsaturated fatty acid is the higher, the cholesterol level is the lower, and HMG-CoA reductase activity is increased.

  • In order to study the effect of feeding moldy corn in the feed and to compare the efficacy of several antidotical treatments, a feeding trial was conducted using broiler chickens. Ground yet low corn was adjusted to contain 20% moisture and then incubated at 35$^{\circ}C$ for 20 days. The number of fungi increased from 11${\times}$10$^4$/g to 42 10$\^$7/g on incubation but aflatoxins (B$_1$, B$_2$, G$_1$, G$_2$) were not detected by TLC test. Moldy corn was included in the experimental diets at the level of 7% with various treatments. Thirty six hatched male broiler chickens were divided into 6 groups and each group was placed for 4 weeks on one of the following treatments: Fresh corn, Moldy corn, Ammoniated (1.5%) moldy corn, Moldy corn+BHT (0.1%), Moldy corn CTC (100ppm) and Moldy corn+Probiotics. Weight gains of the birds fed Ammoniated moldy corn diet, Moldy corn+Probiotics dist and Moldy corn+CTC diet were greater by 6.1%. 7.6% and 3.9% respectively than those fed Moldy corn diet. The feed efficiencies of Moldy corn+Probiotics diet and Moldy corn+CTC diet were better than those of Moldy corn diet. Dry matter contents of the livers of the birds fed Ammoniated moldy corn diet, Moldy corn+BHT diet and Moldy corn diet were lower than those of other treatments. Proteion contents of the livers of the birds fed Moldy corn diet, Moldy corn +CTC diet and Moldy corn+BHT diet were lower than those of other treatments. Moldy corn tended to increase fat content of the livers.

  • This study was objectively performed to identify dietitians' job in the elderly health-care facilities, to assess facilities and dietitian's demographic characteristics, and to determine performance and importance of dietitian's job including the demand of therapeutic diet development. Survey was conducted by mail and samples were the dietitians working in 376 facilities which capacity is over 50 members from nationwide 583 the elderly health-care facilities. Returned questionnaire was 102 and used for statistic analysis. The distributions of the elderly health-care facilities showed 39 the elderly nursing facilities(38.2%), 32 skilled nursing facilities (32.4%), 13 geriatrics hospital facilities(12.7%) and 9 the elderly cost nursing facilities(8.8%). 60.0 percent of the samples showed its menu price as 1,000 to 1,500 won. A cycle-menu program was in-use at the 79.0% facilities, but only 7.1% facilities have been introduced a selected menu system. 92.9% facilities employed only one dietitian. In the demographic characteristics of dietitian only 14.7% dietitian had a clinical dietitian license and 51.5% of respondents answered at least 1 to 3 months internship program is needed. Job activities of the dietitian in the elderly health-care foodservice were identified as 45 activities with 9 dimensions. Job performance score evaluated dietitian oneself was 4.71 of 7 points. The average importance score that the dietitian evaluated their own job was 5.66 points of 7. The job activities shown higher importance but lower performance were therapeutic diet development for in-patients, menu development suitable for taste of the elderly, and leadership. Job performance score by characteristics of dietitian and their elderly health-care facilities was significantly associated with experience of dietitian in elderly health-care (F=4.480, p<0.05), education of dietitian(F=2.659, p<0.01), number of dietitian(F=2.245, p<0.05), and number of employee in foodservice(F=2.607, p<0.05). Most common diseases of the aged was proved as hypertension(81.7%), diabetes mellitus(71.4%), and dementia(65.0%). The therapeutic diets frequently provided were diabetes mellitus diet, dysphagia diet, low sodium diet, high fiber diet, and high protein diet, in order. For those reasons, dietitian in the elderly health care emphasized that the information about therapeutic diet development such as diabetes mellitus diet, dysphagia diet, low sodium diet and hypertension diet must be continuously developed and provided. The result from this study can be applicable to enlarge and enrich job activities of dietitian in elderly health-care foodservice.

  • The effect of dietary calcium and magnesium on the 3-Hydroxy-3-methyl-glutaryl coenzyme A reductase (E.C. 1.1.1.34) in rabbit's liver microsomal protein was studied for a period of 4 weeks using isocalories and isonitro-genous as a basal diet. The experimental rabbits fed the following basal diets, such as crude protein 68.45%, carbohydrates 13.38%, fats 16.17% and added some sorts of calcium and magnesium, according to experimental plan making. The subject rabbits were divided into 9 feeding groups. The results are summarized as follows. Body weight gains per week of the groups fed magnesium and basal diet showed a little bit increase, but the groups fed calcium and basal diet showed a little bit decrease compare with control group. In case of serum magnesium, control group was 9.5mg% groups fed basal diet and magnesium were 8.27mg% in average, groups fed basal diet and calcium were 4.45mg% in average. In case of serum calcium, control group was 15.3mg%, groups fed basal diet and magnesium were 14.6mg% in average, groups fed basal diet and calcium were 14.1mg% in average. There was no great difference between magnesium fed groups in serum calcium. In serum triglyceride, control group was 82.8mg%, groups fed magnesium and basal diet were 60.3mg% in average, groups fed calcium and basal diet were 69.5mg% in average. The calcium fed groups were higher than the magnesium fed groups in serum triglyceride. In serum cholesterol, control group was 80mg%, groups fed magnesium and basal diet were 64.3mg% in average, groups fed calcium and basal diet were 56.3mg% in average. The calcium fed groups were lower than the magnesium fed groups in serum cholesterol. In case of the 3-Hydroxy-3-methylglutaryl coenzyme A reductase activity, control group was 0.998nmol/min/mg protein, groups fed magnesium and basal diet of HMG-CoA were 0.849nmol/min/mg in average.

  • A feeding experiment was conducted on rats to investigate the inhibitive effects of baik-kimchi against the toxicity of Amaranth (Am, Food Red No.2) on growth, fecal weights and bulk, and the digestibility of protein and lipid. The body weight of the Am diet group (5% Amaranth) remained at the lowest level of all diet groups, because of diarrhea symptoms throughout the feeding period, 229.8 g of total body weight or 79.4% of the basal diet group (289.4 g). However, in the baik-kimchi diet group (10% baik-kimchi powder+5% Amaranth) no diarrhea symptoms were evident and total body weight remained at a similar level (280.3 g) to the basal diet group. It therefore appears that baik-kimchi offers an inhibitive effect against the toxicity of Am. In the baik-kimchi diet group, the total fecal weight (173.99 g/3 weeks) was 15 times that of the basal diet group (11.13 g/3 weeks) suggesting that baik-kimchi has the effect of increasing fecal bulk. The large intestine and the cecum of the baik-kimchi diet group were significantly (p<0.05) heavier than those of the Am diet group. The digestibility of protein (50.26%) and lipid (58.37%) in the Am diet group was very low in comparison with these in the baik-kimchi diet group (87.30% and 92.12%, respectively). This result indicates that the low digestibility of these nutrients in the Am diet group was directly responsible for the decrease of weight. Consequently, it is demonstrated that baik-kimchi can inhibit the effects of the toxicity of Am in rats.

  • Inadequate and inappropriate intake of food is known to cause various health issues and diseases. Due to lack of concise information about healthy diet, people have to rely on medicines instead of taking preventive measures in food intake. Due to diversity in food components and large number of dietary sources, it is challenging to perform real-time selection of diet patterns that must fulfill one's nutrition needs. Particularly, selection of proper diet is critical for patients suffering from various diseases. In this article, we highlight the issue of selection of proper diet that must fulfill patients' nutrition requirements. To address this issue, we present a cloud based food recommendation system, called Diet-Right, for dietary recommendations based on users' pathological reports. The model uses ant colony algorithm to generate optimal food list and recommends suitable foods according to the values of pathological reports. Diet-Right can play a vital role in controlling various diseases. The experimental results show that compared to single node execution, the convergence time of parallel execution on cloud is approximately 12 times lower. Moreover, adequate accuracy is attainable by increasing the number of ants.

  • The influence of the ditary containing boiled eggs on the plasma cholesterol level and antithrombotic activity in rats was studied. Rats were fed basal diet(0% boiled eggs) as a control group or diets containing 25% and 50% boiled eggs or a mixed diet with 95% boiled eggs plus 5% $\alpha$-cellulose powder as a experimental groups for 30 days. The bleeding time and whole blood clotting time were significantly(P<0.05) increased by feeding diet containing 25% boiled eggs compared to groups of basal diet, 50% or 95% boiled eggs diets. The plasma clotting time was high in group of 25% boiled eggs diet. However, there were no difference in plasma clotting time among rats fed the dietary boiled eggs. The levels of plasma total cholesterol(TC) and low density plus very low density lipoprotein cholesterol(LDL, VLDL-C) were significantly(P<0.05) highest in group 95% boiled eggs diet compared to others. There were no differences in high density lipoprotein cholesterol(HDL-C) among rats fed the dietary boiled eggs. The levels of plasma TC, HDL-C, LDL$.$VLDL-C and the ratios of HDL-C/TC were not significant among the basal diet, 25% and 50% boiled eggs diets. These results suggest that the intakes of the dietary boiled eggs have the antithrombotic activity and plasma cholesterol lowering effect.

  • This study aimed to verify the nutritional and curative effects of protein hydrolysate in rats with cysteamine-induced duodenal uncer. Duodenal ulcer rat model was established by intraperitoneal injections of cysteamine. Sprague-Dawley, female rats weighing approximately 200g were intraperitoneally injected twice cysteamine(13mg/100g BW) at intervals of 3h per day. This procedure was repeated 3$\times$at intervals of 3d. Animals fed on 10% casein diet for infection periods. After last injection, 4 kinds of diets(10% casein, 20% casein, 10% casein hydrolysate, 20% casein hydrolysate) were given. Gastric montility, trypsin activity in gastrointestinal content, retention rate of nitrogen, plasma total protein, albumin, amino-N, urinary urea nitrogen, creatinine and hydroxyproline were analyzed for nutritional effects of dietary nitrogen levels(10%, 20%) and sources(casein, casein hydrolysate). In duodenal ulcer rat model, there was no differences between 20% casein diet and 20% casein hydrolysate in the view of severeness of ulcer, gastric emptying rate, serum total protein, serum albumin, plasma $\alpha$-amino-N, UUN, creatinine excretion, GFR, nitrogen retention. On the other hand, rats on 10% casein hydrolysate diet group had more curative effect of the ulcer, higher plasma albumin concentration and nitrogen retention than 10% casein diet group. The casein hydrolysate diet group was lower trypsin activity in small intestinal content than the casein diet group, at both nitrogen levels(10%, 20%). The results suggest that protein hydrolysate be applied in diet therapy for the patients with gastrointestinal ulcer.

  • The Purpose of this study is to investigate the effect of soluble dietary fiber psyllium on insulin sensitivity and skeletal muscle glucose transporter 4(GLUT4) protein expression in stroke-prone hypertensive rats(SHRSP) fed a high-fat diet containing 5% of psyllium or cellulose from five to nine weeks of age. Obtained results were as follows : (1) In the psyllium diet group fasting plasma glucose level was significantly reduced and glucose levels upon oral glucose tolerance test were significantly lower than cellulose diet group at 30 min(p<0.05) and 60 min(p<0.01) (2) Skeletal muscle GLUT4 contents were significantly increased in the soleus(slow twitch) and extensor digitorum longus(fast twitch) muscle of psyllium diet group. (3) However there was no difference in insulin levels in the fasting and oral glucose tolerance test. These results indicated that psyllium diet improves peripheral insulin sensitivity but not insulin secretion. In conclusion our present finding suggest that soluble fiber diet is effective to increase insulin sensitivity in SHRSP. From these results it was suggested that soluble dietary fiber supplementation effectively prevents insulin resistance.

  • The purpose of this study was to investigate the improvement effect of mung bean (Phaseolus aureus L.) on the hepatic functional enzyme and catalase activity of streptozotocin (STZ)-induced diabetic rats. Sprague-Dawley (SD) male rats were divided into four groups (n=6), and fed experimental diets containing mung bean meal [basal diet+5% mung bean (BM), basal diet+STZ+5% mung bean (SM)], and control (Basal Diet, BD), BS groups (basal diet+STZ). Serum concentrations of Blood Urea Nitrogen (BUN) and creatinine were significantly decreased (p<0.05) by 5% mung bean supplementation diet. The activities of aspartate transaminase (AST), alanine transaminase (ALT), akaline phosphatase (ALP), lactate dehydrogenase (LDH), amylase and lipase were decreased in the BD, BM and SM group than BS group. The catalase (CAT) activity was significantly increased (p<0.05) in mung bean supplementation diet (BM, SM group) than diabetic group (BS). In vivo experiments with diabetic rats showed that ingestion of mung bean supplementation diet were effective in BUN concentration, and hepatic functional enzyme activities.
