To study antioxidant role of zinc, the effects of dietary zinc deficiency and vitamin E supplementation on lipid peroxidation were studied. Levels of zinc and vitamin E in blood and liver were also measured. Forty Sprague-Dawley male rats aging 8 weeks old were used as experimental animals. Zinc deficient diet (Zn, 0 ppm), zinc normal diet (Zn,36.5 ppm), and vitamin E supplemented diet (1,000 IU ${\alpha}$-tocopherol/kg of diet) were used as experimental diet. During the first three weeks, rats were divided into zinc normal (ZnN, 8 animals) and zinc deficient (ZnD, 32 animals) group. Eight rats from each group were sacrificed to get blood and liver after 3 weeks of experiment. The remaining 24 zinc deficient rat were then divided into zinc normal (ZnDN), zinc deficient (ZnDD), vitamin E supplemented (ZnDE) diet groups. After another 3 weeks of experiment, all animals were sacrificed as well. Thiobarbituric acid reactive substanc (TBARS) levels in plasma and liver, conjugated diene levels in liver were measured as lipid peroxidation index. There were no significant differences in food intake, body weight gain, and food efficiency ratio among groups. Weights of liver per 100 g body weight were not significantly different. There were no significant differences in Zn levels in serum. Plasma and liver TBARS level, and liver conjugated diene level were significantly lower in ZnDE than in ZnDN or ZnDD, and significantly higher in ZnDD than in ZnDN. Therefore, it seems that lipid peroxidation is accelerated by dietary zinc deficiency and recovered partly by vitamin E supplementation.

Hypervitaminosis A occurred in about 30% of foxes of five farms in Choongcheongbukdo-province from October 1989 to February 1990. Clinical signs were loss of appetite, retarded growth, lameness. Radiological changes were decreased density of the long bones, especially fibula, and osteophytes developed either on the lateral condyle of humerus or ulnar just below the semilunar notch. Pathological change was the development of exotosis as is evidenced by radiological examination. Pig liver and lung consisted 30∼55% of feeds from March 1989 to February 1990. The serum concentrations of vitamin A in 2 affected foxes were 45,900 and 47,300 IU/d$\ell$ and the concentrations of vitamin A in the liver were 8,760 and 10,842 IU/gm respectively. It is concluded that the high level of vitamin A in the pig liver and the large amount of pig liver in the feed composition are the etiology of the disease.

This study was conducted to assess blood components caused by metabolic syndrome increasing in postmenopausal elderly women. The blood samples of these subjects were analyzed to investigate the correlation of plasma taurine levels and plasma homocysteine levels, and serum lipid profiles. The subjects were 33 elderly women($72.8{\pm}4.4$ years). Their mean height, weight and BMI were $150.5{\pm}5.7\;cm$, $57.5{\pm}6.3\;kg$ and $25.4{\pm}2.5\;kg/m^2$. 16 women of this study subjects have been chronic diseases such as hypertension or diabetes. Their fasting blood glucose was $98.2{\pm}24.0\;mg/d{\ell}$, and their plasma total cholesterol (TC), HDL-C, LDL-C, triglyceride(TG) were $216.5{\pm}29.9$, $52.1{\pm}10.7$, $145.7{\pm}27.9$ and $141.2{\pm}59.6\;mg/d{\ell}$, respectively. Their blood lipid profiles were higher than the standard levels of metabolic syndrome, thus these levels of lipid profiles may play a role as risk factors on the elderly person. Plasma taurine level of the subjects was $278.5{\pm}48.1\;{\mu}mol/{\ell}$, and their plasma homocysteine level was $12.8{\pm}2.9\;{\mu}mol/{\ell}$. The concentration of plasma vitamin $B_{12}$ was significantly decreased by aging(p<0.05). The correlation of plasma homocysteine and plasma folate showed significantly negative(p<0.05). Thus, the decreased levels of plasma vitamin $B_{12}$ and folate by aging might affect on the plasma homocyteine concentration acting as a risk factor of cardiovascular diseases for elderly person. The correlation of plasma taurine and hemoglobin, and their platelet showed significantly positive(p<0.05). In conclusion, the diet on the elderly person is one of the important factors to prevent their health from chronic diseases. This study recommends that well balanced diets are needed for elderly person to keep their health and prevent from metabolic syndrome.

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 aim of this study was to elucidate the mechanism of anemia associated with Dangguibohyel-tang (DBT) in rats. Using cyclophosphamide-induced (30mg/kg BW) anemic rats, changes in weight gain, the levels of red blood cell (RBC), hematocrit (Hct), platelet and hemoglobin (Hgb), serum vitamin B12, ALT(GPT) levels and erythropoietin (EPO) gene expression were monitored, and compared with DBT (1,000mg/kg BW, 14d)-treated and EPO (1,000IU/kg BW, 14d, s.c.)-treated rats. Food efficiency ratio (FER) were 31.6%, in normal group, 28.1% in cyclophosphamide-induced control group, 31.7% in DBT-treated group and 25.1%, in EPO-treated group after 14 days. The levels of red blood cell (RBC), hematocrit (Hct), platelet and hemoglobin (Hgb) of DBT-treated group were significantly higher than those of control. And DBT extract administered group showed dominant effects on the recovery of Hgb level. Serum vitamin B12 and ALT(GPT) levels were significantly increased at DBT-treated groups. EPO gene expression was decreased 91,9% in control group, 79.6% in DBT-treated group and 53.9% in EPO-treated group, respectively. These results suggest that administration of DBT could prevent human patient from chemotherapy derived anemia by improving hematological value and EPO status.

This stydy was performed to investigate the inhibitory effect of bovine milk on the atherosclerotic rats. Eighty male rats of 5-weeks of age were divided into 4 groups, control, active treatment control fed the atherogenic feed, and skim milk and whole milk groups fed powdered skim or whole milk mixed with the atherogenic feed and observed for 13 weeks. Growth, clinical and pathological changes of the rats were examined. Rats of the 4 groups did not show significant difference of feed intake and weight gain. The level of serum cholesterol, high density lipoprotein cholesterol (HDL-cholesterol) fraction, and inorganics between skim milk and whole milk groups were not significantly different though significant difference was shown between active treatment control and milk groups. Milder calcification and nearosis in aorta, heart and kidney and fat degeneration in liver were seen in the milk groups than were in active treatment control. Marked difference, however, was not found between the skim milk and whole milk groups. Both powdered skim and whole milks could have a helpful effect of vitamin D2-and -cholesterol-induced atherosclerosis in rats.
