Zinc may participate in blood pressure regulation and in the pathogenesis of hypertension. The study examined the relationship between zinc status and blood pressure in obese Korean women. Forty obese women (body mass index (BMI) ${\geq}25kg/m^2$) aged 19-28 years participated in this study. Zinc intake was estimated from one 24 hour recall and 2-day diet records. Serum and urinary zinc concentrations were determined by atomic absorbance spectrophotometry. Systolic blood pressure (SBP) and diastolic blood pressure (DBP) were measured using an automatic sphygmometer. Metabolic variables, such as waist circumference, triglyceride, high density lipoprotein (HDL) cholesterol, fasting glucose, and fasting insulin, were also measured. Dietary zinc intake of obese women was averagely 7.5 mg/day. Serum zinc and urinary zinc concentrations were $13.4{\mu}mol/L$ and $378.7{\mu}g/day$, respectively. Averages of SBP and DBP were 119 mmHg and 78 mmHg. Dietary zinc intake was negatively correlated with SBP after adjusting for energy intake (P < 0.05), but serum and urinary zinc concentrations were not found to be correlated with SBP or DBP. Multivariate linear regression analysis showed that dietary zinc intake was inversely associated with SBP in obese women after adjusting for body weight, energy intake and sodium intake (P = 0.0145). The results show that dietary zinc intake may be an independent risk factor of elevated SBP in obese Korean women.

The purpose of this study was to investigate the distribution patterns of serum triglyceride and cholesterol levels and the influence of environmental and dietary factors in 201 healthy male subjects. The subjects were found to be 53.7% for the normal, 15.4% for the TC, 17.4% for TG and 13.5% for TC.TG group, respectively. Among general characteristics, smoking significantly affected serum lipid levels of subjects (p < 0.05). Among anthropometric factors, body weight, BMI and PIBW significantly influenced the blood lipid patterns. Body weight of TG group was significantly higher than that of normal group (p < 0.05). BMI and PIBW of TG group and TC.TG group were significantly higher than those of normal group (p < 0.05) . In addition, diastolic blood pressure of TG group was significantly higher than that of normal group (p < 0.05). For the food intake, average intake of fruit was significantly higher in normal group than that of TG group (p < 0.05). For nutrient intake, calcium intake was significantly higher in TC group than those of normal and TC.TG group (p <0.05). Intakes of vitamin $B_2$ and C were significantly higher in TC group than those of in TG group (p < 0.05). Serum HDL-cholesterol level was negatively related to meat, poultry, and their products (p <0.05), but serum total cholesterol level positively related to animal lipids (p < 0.05). The results of this study suggest that it is crucial for maintaining adequate serum lipid levels to reduce smoking, blood pressure and to lose body weight. As far as food intake concerned, fruit intake was important in maintaining serum triglyceride level normal, while animal food intake affected serum total cholesterol level adversely.

Purpose: The purpose of this study was to identify the effects of aromatherapy on blood pressure and stress responses of clients with essential hypertension. Method: There were fifty-two subjects divided into an essential oil group, placebo group, and control group by random assignment. The application of aromatherapy was the inhalation method of blending oils with lavender, ylangylang, and bergamot once daily for 4 weeks. To evaluate the effects of aromatherapy, blood pressure and pulse were measured two times a week and serum cortisol levels, catecholamine levels, subjective stress, and state anxiety were measured before and after treatment in the three groups. Data was analyzed by repeated measures of ANOVA, one-way ANOVA, and $X^2-test$ using the SPSS 10.0 program. Results: The blood pressure, pulse, subjective stress, state anxiety, and serum cortisol levels among the three groups were significantly statistically different. The differences of catecholamine among the three groups were not significant statistically Conclusion: The results suggest that the inhalation method using essential oils can be considered an effective nursing intervention that reduces psychological stress responses and serum cortisol levels, as well as the blood pressure of clients with essential hypertension.

The purpose of this study was to determine the relation between serum lipid profiles, apolipoprotein E phenotype, and dietary patterns in a cross-section of healthy individuals from Cheju-Do. Age, gender, anthropometric measurements, blood pressure, dietary consumption, drinking / smoking habits and menopausal status were surveyed. Total cholesterol, LDL-cholesterol, HDL-cholesterol, triglyceride, fasting blood glucose, and insulin levels were measured from overnight fasting blood. The study involved a total of 286 individuals(147 men and 139 women) between the ages of 20 and 60 years old. All of the subjects were recruited from a population of healthy individuals living in Cheju-Do. The results of the study are as follows : 1) Among the males, those in their 20's had the maximum food intake, while those in their 40's had the minimum food intake. For the females, food intake was the highest for those in their 30's. Energy and nutrient intakes were directly proportional to the amount of food intake. Men in their 30's were heavier than other men and women in their 40's were heavier than other women. The activity index for men in their 20's and 30's appeared to be lower than that of men above 40. The activity index of women in their 20's appeared to be lowest among all aged groups, and the index appeared to increase from the age of 30 onwards. 2) In terms of changes In serum constituents with age, men in their 40's appeared to have the highest levels of serum constituents such as lipids, glucose, and insulin. Men in their 50's showed the highest levels of serum LDL-cholesterol and glucose. Men in their 30's showed peak levels of serum triglycerides. On the other hand, women in their 50's appeared to have peak levels of serum total cholesterol, LDL-cholesterol, and triglycerides. There was no ch:ange with age in HDL-cholesterol and insulin levels for men and women. The percentage of the subjects had the following apo E phenotypes : E3/3, 91.3% ; E3/2, 5.4% ; E4/3, 2.5% ; E4/2, 0.7%. Lee's reserch with Korean female college students showed that the percentage of ApoE3/3, E3/2, E 4/2, E4/3, and E4/4 were 84.8%, 6.7%, 6.7%, 0.9%, 0.9%, respectively. The number of samples with ApoE mutation was so small that there was no statistical significance in the relation between apolipoprotein E phenotype and se겨m lipids. 3) To investigate the relati onship between weight and serum constituents, the subjects of this study were divided into three groups by BMI underweight, normal weight, and overweight. The serum constituents of men and women below the age 40 in the overweight groups belonged to the normal domain. On the other hand, serum cholesterol levels of both men and women above the age 40 in the overweight groups remained in the borderline-high region(above 200mg/dl), and the mean value of LDL-cholesterol(above 130mg/dl) and triglycerides of men were above normal. Fasting blood glucose levels also remained in the borderline-high region. Total cholesterol levels of women above the age 40 in the overweight group was in the borderline-high region.

The purpose of this study was to investigate the effect of dietary mushroom powder on blood glucose levels, seam lipid levels, glucose 6-phosphtase (G6Pase), thiobarbituric arid reactive substance (TBARS) and glutathione enzymes in diabetic rats treated with streptozotocin (STZ). Four groups of rats (Sprague-Dawley male rats, 180-200 g) were fed as follows: normal rats were fed a control diet (C), diabetic rats were file a control diet (CD), normal fats were fed a mushroom powder diet (M), and diabetic rals were find mushroom powder diet (MD). Diabetes was induced by single injection of streptozotocin (60 mg/kg B.W.). The animals were fed ad libium each of the experimental diets for five weeks. Food and water intake was determined every day. Blood glucose and serum total cholesterol levels were determined every week. After five weeks, the rats were sacrificed and blood glucose, serum total cholesterol, triglyceride levels and glutathione enzymes were measured. HDL-cholesterol levels were analyzed and LDL-cholesterol concentrations were calculated by equation. There was body weight loss in the diabetic rats, but the MD group showed less body weight loss than the CD group. Blood glucose and serum total cholesterol level of the MD group were lower than those of the CD group (p < 0.05). Also, serum total cholesterol of the M group was lower than that of the C group (p < 0.05). But the serum triglyceride level of the diabetic rats (CD and MD) was higher than that of the normal rats (C and M). However, there was no significant difference between the control diet group and the mushroom diet group. Serum HDL-cholesterol levels of the C group and CD group were higher than that of the M group (p < 0.05), and the MD group was not significantly different. But the serum LDL-cholesterol levels of the M group were lower than those of the C group (p < 0.05). Activity of hepatic microsomal G6Pase significantly increased in the CD and MD, reaching levels higher than those of the C and M groups. Hepateic gutathione S-transferase (GST, glutathione reductase (GR) and glutathione peroxidase (GPX) activity was not significant. But renal GST, GR and GPX activity in the MD group was lower than that of the CD group (p < 0.05). These results suggest that dietary mushroom reduces renal disorders such as oxidation and aging of tissue. In conclusion, dietary mushroom groups reduced blood glucose and cholesterol levels in STZ-induced diabetic rats and renal glutathione enzymes activity was averted in diabetic rats.

Effects of supplemental charcoal powder and vitamin A on growth performance, serum profile and carcass characteristics with 24 Hanwoo steers were inves$\ell$ated. The Hanwoo steers were randomly assigned to one of the three dietary treatments: 1) Control(commercial feed), 2) Tl(commercial feed supplemented with 2% charcoal powder and 0.2 % vitamin A), 3) T2(commercial feed with 2 % charcoal powder). In the age 26 month, body weight of control Tl and T2 were 633.8 kg, 621.0 kg, 619.4 kg, respectively, with not significantly different(P> 0.05). The daily weight gain of control was the highest followed by Tl and T2. The contents of vitamin A(retinol) and total cholesterol in the blood of Tl was higher Tl(56.32 $\ell$ / dt, 163.83 mg/ dz) than the other treatment groups(P < 0.05). The average of WBC value in the blood was 6.86-" 9.83 k / ${\mu}\ell$, RBC value was 7.98 - 11.26 k / ${\mu}\ell$ and blood platelet was 236.7 - 287.0 k / ${\mu}\ell$. But The serum profile in blood was not significantly different between control and treatment groups. The carcass grade and characteristics of all treatments in Hanwoo steers were not significantly different except the texture.

The liver extract of chicks, Gallus domesticus, suffering from hydropericardium syndrome (HPS) was inoculated intraperitoneally into healthy chicks to produce HPS. After inoculation the blood serum and the pericardial fluid of the newly infected chicks were analyzed, at regular intervals for a total period of 72 hours for concentration of proteins, $K^+$ ions, $Na^+$ ions and the LDH activity. The protein content was significantly decreased both in the blood serum (30%) and the pericardial fluid (39%) within 24 hours of inoculation, which was then maintained during the subsequent period. The $K^+$ ions and the LDH activity, on the other hand, were significantly increased in the blood serum (26% and 169%, respectively) as well as the pericardial fluid (131% and 217%, respectively) within 24 hours of inoculation. After 72 hours this increase was, respectively, 43% and 191% in blood serum, and 153% and 200% in the pericardial fluid. Accumulation of $K^+$ ions, and decrease of protein and $Na^+$ ions in the pericardial fluid indicate homoestatic imbalance, which may prove fatal. The increased LDH activity is indicative of heptocytic damage.

This study examined the anti-diabetic effect of onion (Allium cepa. Linn) in the streptozotocin (STZ)-induced diabetic rats. Male Sprague-Dawley rats were divided into normal rats fed control diet or supplemented with onion powder (7% w/w) and diabetic rats fed control diet or supplemented with onion powder. Diabetes was induced by a single injection of STZ (60 mg/kg, ip) in citrate buffer. The animals were fed each of the experimental diet for 5 weeks. Blood glucose levels of rats supplemented with onion were lower than those of rats fed control diet in the diabetic rats. Onion also decreased the total serum lipid, triglyceride, and atherogenic index and increased HDL-cholesterol/total cholesterol ratio in the diabetic rats. Glutathione peroxidase, glutathione reductase and glutathione S-transferase activities were high in the diabetic rats compared to normal rats and reverted to near-control values by onion. These results indicate that onion decreased blood glucose, serum lipid levels and reduced renal oxidative stress in STZ-induced diabetic rats and this effect might exert the anti-diabetic effect of onion.
