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.

We performed a randomized double-blind placebo-controlled trial to determine whether Laminaria japonica extract (LJE) supplement modulates blood glucose, serum lipids and antioxidant systems in type II diabetic patients. We also measured critical parameters assessing safety in liver and kidney functions after LJE supplement. A total of 37 patients (18 males and 19 females) were randomized to either LJE group or placebo group. The treatment group received four 350 mg of LJE capsules (1.4 g, total) per day for 12 weeks. The placebo group received the same dose of cellulose capsules. Baseline characteristics regarding general life style and dietary intake pattern were similar between the two groups. There were no significant influences of LJE supplement except for waist circumference on anthropometric parameters. As the whole, 12 weeks of LJE supplement resulted in a little decrease in fasting blood glucose (FBG) and glycated hemoglobin (HbA1c), but a significant decrease was not observed. Total cholesterol, LDL-cholesterol and triglyceride concentrations were significantly (p<0.05) lowered in LJE group. The antioxidant enzymes, glutathion peroxidase (GSH-px) and superoxide dismutase (SOD) levels were elevated in the LJE group (p<0.05) compared to the placebo. The increase of these enzymes was associated significantly with the decrease of MDA concentration (p<0.05). Furthermore, LJE supplement showed no adverse effects on the functions of liver and kidney. Findings from this study suggest that LJE supplement can help improve serum lipid status in type II diabetic subjects without adverse effects.

The purpose of this study was to improve and strengthen the function of eel extract prepared with 5 brix eel extract (EE), 5 brix eel and plant mix (black garlic, ginseng, black jujube) 0.35 ml extracts prepared and treated with the extract (EIM-1), and 0.7 ml (EIM-2) divided group. The extracts were administered to rats for five weeks during running training, and the lipid profiles and antioxidant enzyme activities were tested. The lipid content in liver and serum were lower than the normal group difference was not significant between groups. Serum total cholesterol was lower in the experimental group than the control group the mixed extract significantly lower level. HDL-cholesterol levels in the eel extract and eel mixed extract significantly increased by feeding the EIM-1 is 2.0 times, EIM-2 is increased by 2.3 times. Liver glycogen content in the experimental group performed the exercise group compared with the normal control group was significantly lower than in EIM is significantly higher than the control group. The TBARS content in the liver and serum was significantly higher than the normal group was lower than the control group. GOT and GPT were significantly decreased compared to the control group. Hepatic catalase activity was significantly increased in the EIM-1 group, and SOD and GSH-px activities were increased in the EIM-1 and EIM-2 groups. Supplementation with the eel and plant mix extract increased the activities of antioxidant enzymes. Thus, intake of the eel and plant mix extract could improve the antioxidant status and combat different types of oxidative stress.
Four different herbs, including rosemary, oregano, basil and sage, along with green tea were individually added to ground beef at different percentages: 0.5, 1.0, and 1.5, respectively. The sensory qualities of the five natural herbs and their antioxidant effects were evaluated using Beef-Yukwonjeon. For the sensory evaluation results, the 0.5% herb addition and the control group generally showed higher acceptability scores than the 1.0% or 1.5% herb addition groups. In particular, the Yukwonjeon made with 0.5% green tea showed higher preferences in the acceptance tests and ranking tests. However, the sensory differences among samples were reduced after 3 days of storage at $6^{\circ}C$. For the results of lipid oxidation without storage, the TBARS values of the herb addition groups were slightly lower than the value of the control group, but not significantly(p>0.05). However, the antioxidant effects of each herb showed higher values over a longer storage period as well as at the higher herb concentrations. The antioxidant effects of the herbs during 7 days' of storage at $6^{\circ}C$ were evaluated as $10.0{\sim}38.5%$ reductions in TBARS values as compared to the group without herbs. Furthermore, the antioxidant effects of the herbs during 30 days' of storage at $-20^{\circ}C$ were shown as $16.8{\sim}27.8%$ reductions in the TBARS value. The green tea showed the highest antioxidant activity against lipid oxidation, because it was acceptable at higher concentrations in the sensory evaluation. These results indicate the potential to produce better quality beef-Yukwonjeon, with herbs, especially green tea.

This study was designed to investigate the effects of enzymatic hydrolysates (EH) from Hamcho (Salicornia herbacea L.) on blood glucose and serum lipid status in streptozotocin (STZ)-induced diabetic rats. Male Sprague-Dawley rats were divided into normal and 5 diabetic groups. The diabetic groups were fed enzymatic hydrolysate-free control (DM) diets or diets supplemented with 0.02% (DM-2), 0.04% (DM-4), 0.08% (DM-8), and 0.16% (DM-16) of enzymatic hydrolysate for 4 weeks. Body weight gains were lower in five diabetic groups than that of the normal group. Blood glucose was decreased in EH-supplemented groups as compared to the normal group, and especially the lowest blood glucose levels were found in DM-4 and DM-8 groups. Activities of three disaccharidase in the middle part of the intestine, such as maltase, sucrase and lactase, in EH-supplemented groups were significantly lower than those of DM group. There was no significant differences in the activities of glutamate oxaloacetate transaminase (GOT) and glutamate pyruvate transaminase (GPT) among all experimental groups. Serum triglyceride in DM group was significantly increased as compared to the normal group, but those of EH-supplemented groups were decreased to the normal level. Total cholesterol level in DM group was higher than EH-supplemented groups and normal group, but that of DM-16 group was significantly decreased to the normal level. HDL cholesterol level in DM group was significantly decreased compared to the normal group, but that of EH-supplemented groups was increased to the normal level. These results suggest that enzymatic hydrolysate from Hamcho has hypoglycemic and hypolipidemic effects on STZ-induced diabetic rats and may be useful as a dietary supplement for the treatment of diabetes.
The free radical theory of aging was introduced in 1956 by Denham Harman. This aging theory proposed that normal aging results from random deleterious damage to tissues by free radical and supplying antioxidant lead to decrease oxidative damage, inhibit aging process. In this study, we investigated antioxidantive effects of four Korean constitutional prescriptions for 'Soum' constitution - Palmulgunjatang(Y1), Sipyimiguanjungtang(Y2), Osuyubujayijungtang(Y3) and Seungyangyikkibujatang(Y4). Antioxidative activity of this prescriptions was examined by 1,1-diphenyl-2-picrylhyrdazyl radicals, superoxide anion radicals, peroxyl radical, hydroxyl radical scavenging effects and erythrocyte hemolysis inhibitory effects. Y2 and Y3 were shown to have relatively high antioxidative activity on this methods. In additions, result of the cytoprotective effects of Korean constitutional prescriptions agianst 2,2'-azobis(amidinopropane) dihydrochloride (AAPH), a free radical initiator, induced cytotoxcity in human hepatoblastoma cell line was similarly obtained. On the basis of this result, we assayed the antioxidative effects of Y2 and Y3 on experimental oxidative damage, induced in mouse by 100mg/kg AAPH. Male ICR mouse were given oral administration of 500mg/kg Y2 and Y3 for 4 weeks. Thiobarbuturic acid reactive substance (TBARS) and protein degradation level in liver, plasma and brain as index of oxidative damage were decreased and thiol compound, total antioxidant status in plasma were increased by Y2 administration. But, Y3 injected group was decreased only protein degradation level in brain. Also, glutathione, a potent water-soluble endogenous antioxidant, concentration was increased by Y2 and Y3 administration in liver and brain. However, superoxide dismutase and catalase activity as a major antioxidative enzyme in vivo were not shown change by Y2 and Y3 administration. On the basis of these result, Y2 have an antioxidative effects on both water-soluble fraction and lipid-solube fraction in cell and tissues. But, Y3 has a lower antioxidative effects on lipid-soluble fraction than Y2 in cell and tissues. These results suggest that Y2 has a antioxidative effects by protect the tissue against oxygen free radical mediated oxidative damage and Y3 has a limited antioxidaitve effects on water-soluble fraction in vivo. Therefore, we make report that Y2 is more effective prescriptions for anti-aging or therapeutics of diseases.
Objectives : In this study, the exposure status of the hazardous substances from incinerators, such as polychlorinated dibenzo-p-dioxins (PCDDs) and polychlorinated dibenzofurans (PCDFs), were studied , and the relationship between the exposure of these hazardous substances and their heath effects on the workers and residents near municipal solid waste (MSW) incinerators and an industrial incinerator investigated. Methods : Between July 2001 and Jure 2002, 13 workers at two MSW incinerators, 16 residents from the area around the two MSW incinerators, 6 residents from the control area, and further 10 residents near an industrial incinerator, estimated to emit higher levels of hazardous substances, were interviewed. Information, including sociodemographic information, personal habits, and work history, detailed gynecologic and other medical history were collected through interviews. Blood samples were also collected from 45 subjects, and analyzed for PCDD/DFs, by high resolution gas chromatography -high resolution mass spectrometry, using the US EPA 1613 method. In addition to the questionnaire survey, urinary concentrations of 8-hydroxydeoxyguanosine (8-OH-dG) and malondialdehyde (MDA) were measured as oxidative injury biomarkers. The urinary concentrations of 8-OH-dG were determined by in vitro ELISA, and the MDA by HPLC, using u adduct with thiobarbituric acid. Results : The PCDD/DFs concentrations in the residents near the industrial incinerator were higher than those in the controls, workers and residents near the MSW incinerators. The average TEQ (Toxic Equivalencies) concentrations of the PCDD/DFs in residents near the industrial incinerator were 53.4pg I-TEQs/g lipid. The estimated daily intakes were within the tolerable daily intake range (1-4 pg I-TEQ/Kg bw/day) suggested by WHO (1997) in only 30% to the people near the industrial incinerator. Animal studies have already shown that even a low body border of PCDD/DFs, such as 10 ng TEQ/kg bw, can cause oxidative damage in laboratory animals. Our study also showed that the same body burden of PCDD/DFs can cause oxidative damage to humans. Conclusions : The exposures to PCDD/DFs and the oxidative stress of residents near the industrial incinerator, were higher than those in the controls, workers and residents near the MSW incinerators. Proper protection strategies against these hazardous chemicals are needed. Because a lower body burden of PCDD/Fs, such as 10ng TEQ/kg bw, can cause oxidative damage, the tolerable daily intake range should be restrictedly limited to 1pg I-TEQ/kg bw/day.
Purpose: A retrospective study was performed to assess the efficacy and tolerance of ${\beta}-blocker$ administration in patients with heart failure and diabetes. Method: Records of 164 patients who were treated for the heart failure condition more than a year were studied retrospectively. Patients were divided into 4 groups based on their diabetes(DM) status and the administration of ${\beta}-blockers$ ($DM+{\beta}-blocker$ group: 14, DM w/o ${\beta}-blocker$: 19, No DM + ${\beta}-blocker$: 62, No DM + no ${\beta}-blocker$: 69). All patients had been receiving conventional therapy such as digoxin, ACE-I, ARB, diuretics, nitrates, aspirin, anticoagulants or lipid-lowering agents. The primary endpoints (death and hospital admission) were recorded during 1 year period and hemodynamic factors (HR, LVEF, SBP, DBP) were obtained from all patient groups before and after 12 months of ${\beta}-blocker$ treatment. To evaluate toxicity of ${\beta}-blocker$, SCr, BUN, AST, ALT and Alkaline phosphatase were obtained. Result: There were less death and hospital admission in DM + ${\beta}-blocker$ group than in DM without ${\beta}-blocker$ group (p=0.014). Relative risk of hospital admission for $DM+{\beta}-blocker$ group over no DM group was 1.17. Long term ${\beta}-blocker$ administration was associated with an improvement of heart rate in patients with DM (P< 0.02) with no significant improvement of LVEF, SBP, DBP. in DM patient. In patient without DM, ${\beta}-blocker$ was associated with improvement in LVEF, HR and DBP (P<0.01, P<0.03), but not in SBP. The incidence of toxicity was similar between the four group with no significant difference. Conculsion: Treatment of heart failure patients with ${\beta}-blocker$ appears to be beneficial in terms of hospital admission event and several hemodynamic factors. The toxicities of ${\beta}-blocker$ treatment were not significant and the treatment is generally well-tolerated in most of the heart failure patients.
Free radicals are thought to be the most important cause of the reperfusion injury subsequent to ischemia. The antioxidant status of the tissue affected by ischemia-reperfusion is of great importance for the primary endogenous defense against the free radical induced injury. Therefore, antioxidant therapy has been shown to be beneficial in neurological disorders such as Alzheimer's disease and cerebral ischemia. In this study, the protective effects of Chungpesagan-tang (CST) was investigated against ischemia/reperfusion-induced cytotoxicity in SK-N-MC neuronal cells It was found out that low concentration of CST was highly effective in protecting neuronal cells against ischemia/reperfusion-induced cytotoxicity. The inhibitory effect of CST on malondialdehyde formation during ischemia/reperfusion-induced oxidative stress in SK-N-MC cells showed obvious dose-dependent responses. Also, CST showed relatively high inhibitory activity to xanthine oxidase induced by ischemia/reperfusion environment Therefore, it is thought that CST has both antioxidant and xanthine oxidase inhibitory effect and can be used for clinical applications for protection of neuronal cells from ischemia-reperfusion injury.
Objectives The aim of this study is to investigate the correlation between degenerative changes in brain [i.e., global cortical atrophy (GCA), medial temporal atrophy (MTA), white matter hyperintensities (WMH)] and neurocognitive dysfunction in Korean patients with Alzheimer's disease. Methods A total of 62 elderly subjects diagnosed with Alzheimer's disease were included in this study. The degenerative changes in brain MRI were rated with standardized visual rating scales (GCA or global cortical atrophy, MTA or medial temporal atrophy, and Fazekas scales) and the subjects were divided into two groups according to the degree of degeneration for each scale. Cognitive function was evaluated with Korean version of the Consortium to Establish a Registry for Alzheimer's Disease (CERAD-K) and several clinical features, including apolipoprotein E ${\varepsilon}4$ status, lipid profile and thyroid hormones, were also examined. Chi-square test and Fisher's exact test were performed to analyze the relationship between the degree of cerebral degeneration and neurocognitive functions. Results Demographic and clinical features, except for the age, did not show any significant difference between the two groups divided according to the degree of cerebral degenerative changes. However, higher degree of GCA was shown to be associated with poorer performance in verbal fluency test, word list recall test, and word list recognition test. Higher degree of MTA was shown to be associated with poorer performance in Mini-Mental State Examination in the Korean Version of CERAD Assessment Packet (MMSE-KC), word list recognition test and construction praxis recall test. Higher degree of white matter hyperintensities was shown to be associated with poorer performance in MMSE-KC. Conclusions Our results suggest that severe brain degeneration shown in MRI is associated with significantly poorer performance in neurocognitive tests in patients with Alzheimer's disease. Moreover, the degree of GCA, MTA and white matter hyperintensities, represented by scores from different visual rating scales, seems to affect certain neurocognitive domains each, which would provide useful information in clinical settings.
