To evaluate the physiological status of laying flocks, the blood chemistry values were measured and analyzed in various ages under different feeding conditions. Total 671 birds from 48 Hyline brown hens flocks from 13 different poultry farms were bled at the ages of day(s) 1, 11, 21, 50, 80, 120, 180, 240, 300, 400, and 500. The 17 blood chemistries including glucose, lipids, proteins, enzymes, electrolytes and metabolic by-products were measured with an autoanalyzer. Blood glucose showed the highest at the hatching day not relate with the dietary carbohydrates and energy, but tended to decrease during the rest of growth stage in hens. Total blood protein, albumin and globulin increased depending on the ages even though dietary protein was decreased. Blood lipid was greatly changed at different growth stages. Cholesterol was the highest at hatching period and maintained consistently until the 120 days of age. It was increased in birds after 180 days of age. HDL was also highest in hatchery, but decreased greatly after 180 days of age. However, TG was the lowest at one day old, but was increased up to 10 times after 180 days of age compared to that of one day old. The enzyme activities were different. AST, ALT, and GGT showed comparatively contained consistently, whereas amylase was slowly decreased. Blood P, Na, K and Cl showed consistency, but Ca content was increased upto two times of the one day of age. The results from this study showed that the blood chemistry values were affected by the general metabolic status of the host with ages not by feeding conditions. Further, the standard data of age-dependent blood chemistry values in the laying flocks were obtained, which can be utilized for early detection of the changes in the physiological status occurred by the infectious or metabolic diseases. The results of these analyses seemed to be useful to increase the productivity of laying flocks through rapid and proper veterinary medical treatments.
Studies were carried out to observe the influence of the Aralia continentalis Kitagawa root on blood pressure and blood constituents of the 24 hypertensive elderly(10 men and 14 women aged over 60). Total subjects were divided into three groups according to taking antihypertensive medications(A), antihypertensive medications and mixing beverages with the Aralia continentalis Kitagawa root(B) or mixing beverages with Aralia continentalis Kitagawa root(C). The systolic blood pressure of C group was significantly lower than that of A and B groups. The diastolic blood pressure of C group was lower than A and B groups. The blood glucose level of C group was a little lower than that of A and B groups. The level of TG increased more in A group than C group and decreased in B group. The levels of T-cholesterol and LDL-cholesterol lowered in B and C groups and HDL-cholesterol level was higher in C group. The GOT, GPT and T-bilirubin levels of C group were significantly higher than others. Mixing beverages with Aralia continentalis Kitagawa root did not affect on blood protein and non-protein nitrogens. In conclusion, mixing beverages with Aralia continentalis Kitagawa root had an effect on lowering blood pressure, blood glucose, T-cholesterol and LDL-cholesterol concentrations.

The purpose of this study was to evaluate whether a daily regimen of green vegetable drink supplementation to male subjects improves the blood pressure and enhances other antioxidant enzyme status, lipid profiles and liver functionalities. Twenty nonsmokers and 19 smokers aged $23{\sim}60$ were given 240 mL of green vegetable drink every day for 8 weeks in addition to their normal diet, and blood samples were drawn before and after the intervention. The 8 weeks of green vegetable drink consumption resulted in a significant decrease of diastolic blood pressure in smokers (p<0.05) as well as in nonsmokers (p<0.01), and systolic blood pressure in smokers (p<0.05). Erythrocyte superoxide dismutase (SOD) activity was significantly increased in both nonsmokers and smokers after the trials. Plasma total cholesterol (TC) level was decreased in smokers and plasma TC and LDL-cholesterol (LDL-C) levels were decreased in nonsmokers while triglyceride (TG) and HDL-cholesterol (HDL-C) was not affected in both nonsmokers and smokers by green vegetable drink consumption. Plasma glutamic pyruvic transaminase (GPT), a marker of liver function was significantly reduced in both nonsmokers and smokers and plasma glutamic oxaloacetic transaminase (GOT) level was significantly reduced in nonsmokers after the supplementation. These results support the hypothesis that green vegetable drink exerts a blood pressure reducing effect and affects not only the activity of antioxidant enzymes, lipid profiles but also plasma GOT and/or GPT levels.

This study was carried out to investigate the effect of Gastrodiae Rhizoma (G. Rhizoma) on blood pressure-lowering in spontaneously hypertensive rats (SHR) fed high-fat diet supplemented with 10% (w/w) of lard during the experimental period of 8 weeks. Forty of male SHR weighing approximately 100 g were randomly divided into eight groups; A: negative control (lard 10%), B: positive control (lard 10% + basal diet + 5 brix water extract), C: lard 10% + 1% G. Rhizoma powder, D: lard 10%+5% G. Rhizoma powder, E: lard 10%+2 brix 50% ethanol extract, F: lard 10%+10 brix 50% ethanol extract, G: lard 10%+2 brix water extract, H: lard 10% + 10 brix water extract. A gain in weight did not differ significantly among dietary groups, but a little higher in control groups than in G. Rhizoma dietary groups. Except for spleen, weights of liver, kidney and testis are significantly different among dietary groups. Serum total cholesterol concentration was markedly higher in control groups than in G. Rhizoma groups (p<0.05), however, there was no significant difference in serum triglyceride. Except for negative control (A) and group D, serum HDL concentration was significantly higher in G. Rhizoma groups (p<0.05). On the other hand, serum LDL concentration was significantly higher in two control groups (A, B) and markedly lower in E and G groups of hot water extract of G. Rhizoma (p<0.05). Reference systolic blood pressure (BP) showed average 185.7$\pm$5.8 mmHg for 4 weeks after feeding high-fat diet, and the pressure was measured on every 7 days intervals after feeding of G. Rhizoma diet. Comparing with reference BP before feeding of G. Rhizoma diet, the groups of 50% ethanol (E, F) and water (G) extracts on BP level after 28 days were shown to be reduced at 16.8, 20.2 and 11.7 mmHg, respectively. When the pressure (187 mmHg) of group A was considered as 100%, the reduction rate of BP in group F was 11% (20.5 mmHg). These results indicated that the groups treated with ethanol extracts of G. Rhizoma showed to have lower blood pressure level compacred to the groups treated with whole powder or water extracts of G.Rhizoma in SHR fed with high-fat diet.

The effects of the salts fortified with seaweed functional components on blood pressure, serum minerals, and hematochemicals in spontaneously hypertensive rats (SHR/NCrj) and normotensive rats (WKY/NCrj) were investigated. SHR and WKY rats were assigned to four groups, with 8 and 6 rats in each group: laver salt (A), fucoidan+laver high salt (B), fucoidan + laver low salt (C) and refined salt as a control (D). The final blood pressure (BP) of SHR and WKY species in contrast with reference BP were low in groups A and C as compared with control group. In terms of serum mineral content, $Na^+$ levels were similar in SHR and WKY, but $K^+$ levels were higher in the group B in SHR. Serum triglyceride levels were lower in groups A and C, but the levels of HDL- and LDL- cholesterol were significantly higher and lower in group A than those of controls, respectively (p<0.05). These results demonstrated that the salts fortified with laver might suppress blood pressure in rats, and also may improve mineral and lipid metabolism.

This study was designed to evaluate the single dose toxicity and the protective effect of water extract of Cordyceps militaris grown upon Protaetia dreujtarsis (CMPD extract) on liver damage on carbon tetrachloride ($CCl_4$)- induced acute hepatotoxicity in Sprague-Dawley (SD) rats. The CMPD extract was once administered orally to both sexes of rats at dose of 2,000, 1,000 and 500 mg/kg body weight, the recommended maximum limit dose for acute toxicity. Neither significant toxic signs nor death was observed during the observation period. These results indicate that $LD_{50}$(lethal dose of 50%) of CMPD extract is greater than 2,000 mg/kg body weight in SD rats. To investigate also the effect of hepatoprotection of CMPD extract, SD rats were orally treated with CMPD extract (50, 25 and 12.5 mg/kg body weight) or silymarin (25 mg/kg body weight) before and after administration of $CCl_4$ (2 mL/kg body weight, 20% $CCl_4$ in olive oil). Treatment with CMPD extract or silymarin could decrease the GPT (glutamic-pyruvic transaminase) and GOT (glutamic-oxaloacetic transaminase) levels in serum when compared with $CCl_4$-treated group. Therefore, the results of this study show that CMPD extract can be proposed to protect the liver against $CCl_4$-induced hepatic damage in rats.

Purpose: The purpose of this study was to evaluate the dietary potassium intake, Na/K intake molar ratio, consumption of 18 food groups, and foods contributing to potassium intake of Korean adults as well as the relationships among quartile of potassium intake level and blood pressure, blood biochemical index. Methods: This study was conducted using the Korea National Health and Nutrition Examination Survey, 2007~2010. The total number of subjects was 20,291. All analyses were conducted using a survey weighting to account for the complex survey design. Results: Overall average intakes of potassium were 2,934.7, 3,070.6, 3,078.1, and 3,232.0 mg/day, and they significantly increased by year in Korean adults. The average dietary potassium intake was close to adequate intake (AI), whereas that of women was considerably lower than the AI. The Na/K intake molar ratio in males (2.89~3.23) was higher than in females (2.62~2.95). The major food groups contributing to potassium intake were vegetables, cereals, and fruits/meats. The two major foods contributing to potassium intake were polished rice and cabbage kimchi. The rankings of food source were as follows; polished rice > cabbage kimchi > potato > oriental melon > sweet potato > seaweed > radish > apple > black soybean. In 50~64 year old females, systolic blood pressure (SBP) significantly decreased (p < 0.01) and HDL-cholesterol significantly increased (p < 0.05) as potassium intake increased. Triglyceride (TG) was significantly higher in the other quartile of potassium intake level than in the first quartile (p < 0.05). Conclusion: In conclusion, our study suggests the need for an appropriate set of dietary reference intakes according to caloric intake by sex and age groups and for development of eating patterns to increase potassium intake and decrease sodium intake.

This study was conducted to examine the changes in serum lipid components and blood glucose by krill (Euphausia superba) meal and sodium fluoride (NaF) in rats fed on experimental diets and administered orally to NaF 10 mg for 5 weeks. Body weight of rats decreased as the amount of krill meal diet increased, it was observed the basal diet plus NaF group (BF group) compared to the lower basal diet group (BD group). The serum concentrations of total cholesterol, LDL (low-density lipoprotein) cholesterol, free cholesterol, triglyceride (TG), phospholipid (PL) and blood glucose in serum were higher in the BF group than the 10% krill meal group plus NaF 10 mg (KF10 group) or BD group, the 20% krill meal plus NaF 10 mg group (KF20 group), the 30% krill meal plus NaF 10 mg group (KF30 group). Conversely depending on the content of krill meal for the HDL (high-density lipoprotein) cholesterol level, it showed higher results. The concentration of total protein was no significant difference among the groups (p<0.05). The results indicate that a krill meal diet effectively inhibited increases in lipid elevation and blood glucose level in the sera of rats.

Effects of soy protein concentrate (SPC) containing isoflavone and casein diets on plasma phospholipid (PLs)-fatty acid patterns were investigated in 7-& 40- wk old female rats. Diets containing 16% SPC (soy/young:SY, soy/old: SO) and casein (casein/young : CY, casein/ old: CO) supplemented with 0.5% cholesterol were fed for 4 wks. Fatty acid compositions of plasma PLs were determined by TLC and GLC. Compared to the dietary protein effects, age effects on serum lipids were more profound. The levels of total cholesterol (Chol.), triglyceride, HDL-Chol., (LDL+VLDL)-Chol. and atherogenic index (AI) were higher in older groups (OC & OS) than younger groups (YC &. YS). Soy groups had higher Ell)L-Chol. level and lower (LDL+ VLDL)-Chol. and AI, compared with casein groups. The compositions of C22:0, Cl8:1 $\omega$9 and sum of MUFA in plasma PLs were significantly higher in casein group (CY & CO) than soy group (SY & SO), but those of sum of SFA were higher in soy group. The compositions of C22:0, Cl8:1 $\omega$9, C22:1, Cl8:3$\omega$3 and C22:4$\omega$6 were higher and those of C22:6$\omega$3, sum of $\omega$3, Cl8: 2$\omega$6 C20:4$\omega$6, sum of $\omega$6 and sum of PUFA were lower in plasma PLs of younger rats. The average P/S and $\omega$3/$\omega$6 ratio in older group was higher. The $\Delta$-7 desaturation index (16:0⇒16:1$\omega$7) and $\Delta$-9 desaturation index (18:0⇒18:1$\omega$9) were lower in soy group than casein group, while $\Delta$-6 and $\Delta$-5 desaturation index were not affected by dietary protein. The $\Delta$-4 desaturation index (22:4$\omega$6⇒22:5$\omega$6) were higher and elongation index (20:4$\omega$6⇒22:4$\omega$6) were lower in older group. The ratio of the products of $\omega$3 fatty acid series (Cl8:3) was significantly higher in older group, which indicated that age affected the plasma PUFA metabolism. On the other hand, older rats had higher serum cholesterol level compared with younger rats. Taken together, these changes in fatty acid composition might cause minimal changes in tile membrane fluidity induced by the increase serum cholesterol level.
Objectives: This study was designed to examine the effects of extracts of Ojeoksangamibang($W{\check{u}}j\bar{i}s\check{a}nji\bar{a}w\grave{e}if\bar{a}ng$) on the lipid lowering, anti-oxidation and concentration of proinflammatory cytokines and was investigated on hyperlipidemic rats.
