This study was done to investigate and compare the nutritional status and plasma lipids in the diabetes and control elderly. Subjects were 105 persons (male 32, female 73) aged over 65 years and visited public health centers in Ulsan area. The subjects were divided into 2 groups, diabetes and control group. Athropometric measurement, dietary intakes, and plasma biochemical indices were examined. Body Mass Index (BMI), Percentage of Ideal Body Weight (PIBW) and Waist-Hip Ratio (WHR) of diabetes group were higher than those of control group. Overall eating behavior were worse in diabetes group than those of control group. There was no significant difference in smoking and exercise status among groups. The ratio of drinkers was significantly higher in control group. But the amount of alcohol consumed at once was higher in the diabetes group. There was no significant difference in most nutrient intakes between males and females. The intakes of fiber, natrium (Na), vitamin A, and $\beta$-carotene were significantly higher in diabetes group than control groups while that of potassium (K) was lower in diabetes group. Diabetes group had the higher levels in triglyceride, VLDL-cholesterol, Chol/HDL-cholesterol ratio, LDL/HDL-cholesterol ratio, while they had lower HDL-cholesterol level. Overall results might imply that the elderly with diabetes have to be more careful to their meals and health-related behaviors to increase the likelihood of a healthier life.
Malnutrition is a common problem in patients undergoing maintenance hemodialysis(HD) and compromised food intake is an important cause. Malnutrition is one of the important factors influencing mortality in chronic HD patients. We investigated the nutritional parameters of 50 Korean HD patients(mean age: 46.9 $\pm$ 10.3y, men : 23, women : 27) by measuring anthropometric and biochemical blood indices and assessing food intake using 24-h recall method. Also we administered two questionnaires, one for assessing nutritional knowledge about renal disease and dietary therapy, the other for measuring dietary habits related to dietary therapy. According to the distribution of BMI, 21.3% of HD patients were underweight. The hematological values of HD patients, such as plasma hemoglobin, hematocrit, and total lymphocyte count were below the normal range. The serum cholesterol levels were 133.2 $\pm$ 30.5mg/dl. HD patients took energy and protein only 77.5% and 83.1%, respectively, of their RDA. There were significantly positive correlations between nutritional knowledge and intake of nutrients, such as energy, fat, cholesterol, iron, potassium, vitamin B$_1$, vitamin B$_2$, and niacin. Also, there was a significantly positive correlation between nutritional knowledge and dietary habits(r = 0.317, p < 0.05). In conclusion, Korean HD patients showed mild malnutrition and suboptimal nutrition intake. It can be postulated that the dietary intake can be increased by nutrition education improving nutritional knowledge and correcting the dietary habits of HD patients.
This study conducted to assess the effectiveness of nutrition education program for elderly females with various diseases. Forty subjects(hypertension ; 20, diabetes ; 12, hyperlipidemia ; 8) out of 56 completed the 7 weeks nutrition education program. The nutrition education program was based for healthy food habits and dietary guidelines for each specific disease. It also included practicing individualized menu planning and exercising program. Energy, calcium, iron, vitamin A and ash intakes significantly increased in the hypertension group. total sodium intake did not decrease, however sodium intake per kcal decreased significantly(p〈0.05). Elderly with diabetes did not show any changes in dietary intakes. Dietary protein, plant fat, ash, and sodium intakes were significantly elevated(p〈0.05), but cholesterol intakes significantly decreased(p〈0.05) in the hyperlipidemic group. Elderly with hypertension agreed strongly with changes of food habits such as increasing milk intake, and decreasing Kimchi, soup, pickles and salty food, and table salt intakes after nutrition education. Diabetic elderly showed significantly improved food habit scores in decreasing white rice intake, sugar intake and increasing sea-weed consumption, vegetable consumption and exercise. Hyperlipidemic elderly did not show much improvement in food habit scores except in biochemical indices. However, mean serum glucose and atherogenic index decreased in the diabetic and hyperlipidemic groups after education, respectively.
Over the past few years, anthocyanin has been demonstrated to exert potentially anti-oxidative and bioavailability effects including anti-cardiovascular disease and cancer-preventive effects in humans. This study was conducted to assess the toxicity of anthocyanin extracts from black soybean seed coats via oral administration in a mice feeding test. The final anthocyanin-containing products induced signs of toxicity on mortality in the 4-week feeding test. The incidence of clinical signs and changes in body and organ weight were also not observed in all anthocyanin-treated groups as compared with the control groups. In hematology analysis, RBC indices concluding MCV, MCH, and MCHC and WBC differential counting such a NEU, LYM, MONO, EOS, and BASO evidenced no significant differences between the anthocyanin treatment and control groups. The biochemical parameters in serum analysis - ALT, AST, BUN, Crea etc.- were also not significantly altered in those groups. Absolute and relative organ weights were not increased after 4 weeks of treatment with anthocyanin extracts in mice. In conclusion, anthocyanin extracts from the black soybean has biological activity without any toxic effects, which also suggests that the consumption of soy containing anthocyanin products may be a good source for health and medical supplies.
The effect of dietary supplementation of the two oriental medicinal prescriptions, Sypjeondaebotang or Jahyulyanggeuntang, on iron bioavailability was evaluated in rats which were depleted of iron by being fed an irondeficient diet for 4 weeks. Seventy two iron-depleted rats were randomly divided into 3 groups (n = 24) , and fld one of the following experimental diets for 4 (n = 8), 12 (n = 8), and 25 days (n = 8) : Control diet (CD), Sypjeondaebotang-supplemented diet (SD), Jahyulyanggeuntang -supplemented diet (JD). The CD contained 20 mg Fe/kg diet as FeSO4, and the SD or JD was identical except that the respective oriental medicinal prescription extract was included at the level of 4 g/kg diet. Animals fed the SD and JD for 25 days consumed significantly less food (p<0.001), but showed no change in food efficiency ratio compared to those that were fed the CD. Serum iron concentration and transferrin saturation values were significantly higher in rats fed the SD for 25 days compared to those that were fed the CD for the same period (p < 0.05). The values of serum UIBC (p < 0.05) and TIBC (p > 0.05) were lower in rats fed the SD compared to those fed the CD. Dietary supplementation of Sypjeondaebotang during the period of iron repletion significantly increased blood levels of hemoglobin (p < 0.05) and hematocrit (p < 0.01) measured at day 12, and increased mean corpuscular volume (p < 0.05) measured at day 25, compared to the values for the CD rats. Regression analyses of hemoglobin-repletion bioassay data from rats fed the SD and JD showed the relative biological values of 123% and 99%, respectively, calculated against the slope for the CD rats. Apparent iron absorption and retention values were also significantly lower (p < 0.05) in rats fed the SD for 25 days than those for the CD rats. Based on the results from diverse biochemical indices of iron status and the chemical balance study, the effect of Jahyulyanggeuntang on iron bioavailability appears to be less prominent than that for Sypjeondaebotang. Taken together, these results indicate that Sypjeondaebotang has a positive effect in restoring iron depletion by increasing the iron bioavailability in rats.
The present study was undertaken to investigate whether or not the hepatoprotective activity of acetylbergenin was superior to bergenin in carbon tetrachloride ($CCl_4$)-intoxicated rat. Acetylbergenin was synthesized by acetylating bergenin, which was isolated from Mallotus japonicus. The hepatoprotective effects of acetylbergenin were examined against $CCl_4$-induced liver damage in rats by means of serum and liver biochemical Indices. Acetylbergenin was administered orally once daily for 7 successive days, then a 0.5 ${m/kg}$ mixture of $CCl_4$in olive oil (1:1) was intraperitoneally injected at 12 h and 36 h after the final administration of acetylbergenin. Pretreatment with acetylbergenin reduced the elevated serum enzymatic activities of alanine/aspartate aminotransferase, sorbitol dehydrogenase and $\gamma$-glutamyltransferase in a dose dependent fashion. Acetylbergenin also prevented the elevation of hepatic malondialdehyde formation and depletion of glutathione content dose dependently in $CCl_4$-intoxicates rats. In addition, the decreased activities of glutathione S-transferase and glutathione reductase were restored to almost normal levels. The results of this study strongly suggest that acetylbergenin n has potent hepatoprotective activity against $CCl_4$-induced hepatic damage in rats by glutathione-mediated detoxification as well as having free radical scavenging activity. In addition, acetylbergenin doses of 50 ${mg/kg}$showed almost the same levels of hepatoprotection activity as 100 ${mg/kg}$ of bergenin, indicating that lipophilic acetylbergenin is more active against the antihepatotoxic effects of $CCl_4$ than those of the much less lipophilic bergenin.
The purpose of this study was to assess the iron nutritional status and dietary iron availability of postmenopausal women residing in Jeonju area. The anthropometric parameters, nutrient intake and biochemical status of iron were measured from 57 postmenopausal women aged 50∼74 years old. Mean values of hemoglobin(Hb), hematocrit(Hct), serum iron(Fe), total iron binding capacity(TIBC) and serum ferritin(Ferritin) concentration were 12.82${\pm}$1.03g/dl, 37.68${\pm}$2.99%, 92.60${\pm}$46.66ug/dl, 353.0${\pm}$54.48ug/dl, 86.86${\pm}$100.7ug/ιrespectively. Prevalence of iron deficiency greatly varied by indices from 14.04% when judged by Ferritin(<20ug/ι) to 40.4% by TIBC(>360${\mu}$g/dl. The anemic subjects assessed with Hct percent(36%) represented 22.8%, whereas 21.1% of the subjects possessed less than 12g/dl of Hb. Ferritin concentration showed a significantly negative correlation with TIBC(r=-0.343, p<0.01) and a positive correlation with MCHC(r=0.361, p<0.01). The mean daily intake of iron was 10.62mg and intake of heme iron was 5.3%(0.56mg) of total iron intake. Total absorbable iron caculated by the method of Monsen was 0.49mg anti bioavailability of dietary iron was 4.61%. Ferritin Concentration was positively associated with total iron intake(r=0.264, p<0.05), dietary nonheme iron(r=0.286, p<0.05) and iron of animal food (r=0.364, p<0.01). But Ferritin concentration was not correlated dietary heme iron(r=-0.137, p>0.05). Major food groups of iron intake were vegetables(20.15%), cereals(19.59%) and fishes(12.34%) in postmenopausal women. Intake of eggs was positively associated with Ferritin(r=0.473, p<0.01).
The purpose of this study was to investigate the effects of smoking and/or alcohol drinking on the nutrient intake, nutritional status, and eating habits of adult males. The subjects were 157 male adults aged 20-49 living in Daejon. Interviews with questionaire on smoking and alcohol drinking habits and eating habits, anthropometric measurement, biochemical blood test, and dietary assessment by one-day 24 hour recall and two-day diet record were carried out. The subjects were divided into four groups : control (non-smoking and non-drinking), drinking only, smoking only, and the both(drinking and smoking). The average numbers of smoked cigarettes were 17.8/d and 19.1/d in the smoking only group and the both group, respectively. The frequency of alcohol drinking was 8.3 times/month and 11.6 times/month in the drinking only group and the both group, respectively. Height was significantly higher(P 0.05) in the drinking only group than in the none and smoking only groups, while the other anthropometric indices were not different among the four groups. There were positive correlations between smoking and drinking or coffee intake. Alcohol drinking increased eating-out frequency and the intakes of energy, protein, dietary fiber, vitamin A, B$_1$,$ B_6,$ Fe and P, while smoking decreased snack frequency and intakes of energy, protein and vitamin $ B_6,$. Blood pressure was not changed in the smoking only and drinking only groups compared to the none group, while systolic blood pressure was elevated in both group(P 0.05). Alcohol drinking significantly elevated(P 0.05) serum total cholesterol and LDL-cholestrol level, while smoking did not change the serum lipid and cholesterol levels. Hemoglobin nd MCHC levels were significantly elevated(P 0.05) by smoking. From these data, it is suggested that both smoking and drinking have influence on some eating habits and nutrient intakes, and especially alcohol drinking can induce hypercholesterolemia.

The objective of this study was to evaluate the effects of Lactobacillus acidophilus ATCC 43121 and L. fermentum MF27 on biochemical indices in the serum, cholesterol metabolism in the liver and mucin expression in the gallbladder in lithogenic diet (LD)-induced C57BL/6J mice to determine the preventive effects of lactobacilli on gallstone formation. By the end of 4 wk of the experimental period, mice fed on a LD with high-fat and high-cholesterol exhibited higher levels of total and low-density lipoprotein cholesterol in the serum compared to mice fed on control diet or LD with L. acidophilus ATCC 43121 (LD+P1; p<0.05). Cholesterol-lowering effects observed in the LD+P1 and LD with L. fermentum MF27 (LD+P2) groups were associated with reduced expression of 3-hydroxy-3-methylglutaryl coenzyme A reductase in the liver compared to the LD group (p<0.05). Furthermore, expression of the gel-forming mucin, including MUC5AB and MUC5B, was suppressed in the LD+P1 and LD+P2 groups compared to the LD group (p<0.05). Therefore, steady intake of both L. acidophilus ATCC 43121 and L. fermentum MF27 may have the ability to prevent the formation of cholesterol gallstones in LD-induced C57BL/6J mice.
To determine the true digestible phosphorus (TDP) requirement of growing pigs, two experiments were designed with the experimental diets containing five true digestible P levels (0.16%, 0.20%, 0.23%, 0.26% and 0.39%) and the ratio of total calcium to true digestible P (TDP) kept at 2:1. In Experiment 1, five barrows (Duroc${\times}$Landrace${\times}$Yorkshire) with an average initial body weight of 27.9 kg were used in a $5{\times}5$ Latin-square design to evaluate the effect of different dietary P levels on the digestibility and output of P and nitrogen. In Experiment 2, sixty healthy growing pigs (Duroc${\times}$Landrace${\times}$Yorkshire) with an average body weight (BW) of 21.4 kg were assigned randomly to one of the five dietary treatments (12 pigs/diet), and were used to determine the true digestible phosphorus (TDP) requirement of growing pigs on the basis of growth performance and serum biochemical indices. The results indicated that the true digestibility of P increased (p<0.05) linearly with increasing dietary TDP level below 0.26%. The true P digestibility was highest (56.6%) when dietary TDP was 0.34%. Expressed as g/kg dry matter intake (DMI), fecal P output increased (p<0.05) linearly with increasing P input. On the basis of g/kg fecal dry matter (DM), fecal P output was lowest for Diet 4 and highest (p<0.05) for Diet 5. The apparent digestibility of crude protein (CP) did not differ (p>0.05) among the five diets, with the average nitrogen output of 12.14 g/d and nitrogen retention of 66% to 74% (p>0.05), which suggested that there was no interaction between dietary P and CP protein levels. During the 28-d experimental period of Experiment 2, the average daily gain (ADG) of pigs was affected by dietary TDP levels as described by Eq. (1): $y=-809,532x^4+788,079x^3-276,250x^2+42,114x-1,759$; ($R^2=0.99$; p<0.01; y = ADG, g/d; x = dietary TDP, %), F/G for pigs by Eq. (2): $y=3,651.1x^4-3,480.4x^3+1,183.8x^2-172.5x+10.9$ ($R^2=0.99$; p<0.01; y = F/G; x = dietary TDP, %), and Total P concentrations in serum by Eq. (3): $y=-3,311.7x^4+3,342.7x^3-1,224.6x^2+195.6x-8.7$ (R2 = 0.99; p<0.01; y = total serum P concentration and x = dietary TDP, %). The highest ADG (782 g/d), the lowest F/G (1.07) and the highest total serum P concentration (3.1 mmol/L) were obtained when dietary TDP level was 0.34%. Collectively, these results indicate that the optimal TDP requirement of growing pigs is 0.34% of the diet at a total Ca to TDP ratio of 2:1.
