This study was conducted to evaluate the effects of indigenous herbal supplements on growth, blood metabolites and carcass characteristics in the late fattening period of Hanwoo steers. In a 6 month feeding trial, thirty Hanwoo steers ($647{\pm}32$ kg) were allotted to one of 5 treatment groups, control (basal diet contained lasalocid), licorice, clove, turmeric and silymarin, with six steers per pen. All groups received ad libitum concentrate and 1 kg rice straw/animal/d throughout the feeding trial. Blood samples were collected at the beginning, middle, and the end of the experiment and the steers were slaughtered at the end. Blood glucose, triglyceride, total protein, and albumin concentrations were higher in the turmeric treatment compared with other treatments. Blood urea nitrogen and creatinine concentrations were highest (p<0.003 and p = 0.071, respectively) in steers treated with silymarin. Alanine aminotransferase activity was lower (p<0.06) for licorice and silymarin compared with the control group. There were no alterations in serum aspartate aminotransferase and gamma glutamyltransferase activities as a consequence of herb treatments (p = 0.203 and 0.135, respectively). Final body weight, body weight gain, average dairy gain and dry matter intake were not significantly different among treatments. Yield grade, marbling score and quality grade were higher for silymarin group than those of the control group (p<0.05). Therefore, the results suggest that silymarin can be used an effective dietary supplement as an alternative to antibiotic feed additive and a productivity enhancer, providing safe and more consumer acceptable alternative to synthetic compounds during the late fattening period of steers.

Purpose: The purpose of this study was to examine relationships among blood glucose, HbA1c, and self management comparing these with general and illness characteristics of subjects with Type II Diabetes living in the community. Methods: Using a comprehensive survey developed for the study, data were collected from 82 type II diabetes patients who were registered at five community health departments. The variables of self management, blood glucose and HbA1c were assessed by nurses. Data were analyzed with descriptive statistics including t-test, ANOVA and Pearson's correlation coefficient to compare self management and level of HbA1c by subject's general and illness characteristics and to examine the relationships among variables. Results: About 73.2% of the subjects' HbA1c were 7.0% or higher and 54.9% of subjects' blood glucose were 200 mg/dL or higher. The level of self management was moderate. Most frequently perceived reasons for failure of blood glucose control were dietary failure (32.9%). There was significant relationship between self management and HbA1c(r=-.223, p=.040). The mean score of self management were higher among female (t=-2.37, p=.021), who are not on diabetes medication (t=6.70, p=.011). Conclusion: Comprehensive intervention is needed to improve dietary self management, especially for male and those who is on diabetes medication.

The purposes of this study were to set up the method of the natural killer(NK) cell activity assay using the flow cytometer and to examine the characteristics and distribution of the NK cell during rat hepatocarcinogenesis. Forty five male 6 week-old specific pathogen free(SPF) Sprague-Dawley rats were randomly divided into three groups. Group I was the non-treated control and given normal diet and water. Group II was treated with diethylnitrosamine(DEN, 200mg/kg, i.p.) and partial hepatectomy. Group III was treated with DEN, partial hepatectomy and 0.05% phenobarbital sodium in water from 3 to 16 weeks. All animals were examined the morphology of the large granular lymphocyte(LGL), the LGL percent of the total lymphocytes and the LGL conjugation rate with YAC-1 cell in peripheral blood, spleen and liver. Moreover, activity of the LGL isolated from peripheral blood lymphocytes was determined using the flow cytometer. As results, LGL were observed in the peripheral blood, spleen and liver. LGL were observed the relatively faintly staining basophilic cytoplasm with granules, and eccentric, often kidney-shaped nuclei in Giemsa stain. Its size was $11{\sim}13{\mu}m$. LGL percentage of the isolated lymphocytes in peripheral blood, spleen and liver were 1.8~2.3%, 1.3~1.4% and 0.87~0.99%, respectively. LGL conjugation rate with YAC-1 cell was shown to be peripheral blood(9.3~10.3 %) > spleen(7.7~8.7%) > liver(5.6~7.0%). The activity of the LGL isolated from peripheral blood lymphocytes in Group I, II and III was 33.7%, 30.5% and 35.4%, respectively. However, all values were not significantly between groups.

Purpose: This study was performed to analyze the levels of blood pressure and to identify good or poor blood pressure control (BPC) groups among hypertension patients. The study was based on the Korea National Health and Nutrition Examination Survey (KNHANES VI and VII) conducted from 2013 to 2016. Methods: The sociodemographic and clinical data of 4,151 Korean hypertension patients aged 20-79 years and who were taking antihypertensive medications was extracted from the KNHANES VI and VII database. Descriptive statistics for complex samples and a decision-tree analysis were performed using the SPSS WIN 24.0 program. Results: The mean age was $62.46{\pm}0.21years$. The mean systolic blood pressure (SBP) was $128.07{\pm}0.28mmHg$, and the diastolic blood pressure (DBP) was $76.99{\pm}0.21mmHg$. 71.9% of participants showed normal blood pressure (SBP < 140mmHg and DBP < 90mmHg). From the decisiontrees analysis, the characteristics of participants related to good BPC group were presented with 9 different pathways same as those from the poor BPC group. Good or poor BPC groups were classified according to the patients' characteristics such as age, living status, occupation, education, hypertension diagnosis period, numbers of comorbidity, perceived health status, total cholesterol, high density lipoprotein-cholesterol, alcohol drinking per month, and depressive mood. Total cholesterol level (< 201mg/dL or ${\geq}201mg/dL$ cutoff point) was the most significant predictor of the participants' BPC group. Conclusion: This decision-tree model with the 18 different pathways can form a basis for the screening of hypertension patients with good or poor BPC in either clinical or community settings.

The purpose of this study is to assess the effects of heavy metal concentrations in the blood and urine of the general population. This research had been conducted from April to December 2008, studying 545 residents of Daejeon and Chungcheong Province. Through the concentrations of heavy metals(Pb, Cd, Hg, As, Mn) in the biota samples and questionnaires, the residents heavy metal exposure level and the influential factors according to personal characteristics or lifestyle were evaluated. As to the heavy metal concentration in the blood and urine of the comparing region, were As and Mn statistically significant(p<0.01, p<0.05). Blood lead and urinary mercury concentrations were higher in males than females. The heavy metal concentration for each age group increased blood mercury. The concentration of all heavy metals were higher in the drinkers than in the non-drinkers. Blood lead and mercury concentrations were higher in the smokers than in the non-smokers, but the urinary cadmium, arsenic and blood manganese was higher in the non-smokers than in the smokers. As to the blood lead and urinary cadmium concentration according to the food preference fish showed high concentration. To clarify the factors affecting the heavy metal concentration in biota among subjects multiple regression analysis was conducted. As a results, it turned out that as to lead content in blood, sex, age and smoking have influence on the subjects with explanatory adequacy of 14.0 %. These results demonstrated that the factors affected the concentrations of heavy metals in blood and urine. The results of this study could be used as the foundational data for setting the health risk assessment.

Purpose: This study aimed to assess the reference values and factors influencing blood lead levels among Korean adolescents. Methods: The study population consisted of 1,585 adolescents (801 males, 784 females; aged 10-19 years) who participated in the Korea National Health and Nutrition Examination Survey 2010-2013. We analyzed blood lead concentrations in relation to demographic/lifestyle characteristics for all participants. "Reference values" of blood lead levels were calculated as the upper limit of the 95% confidence interval of the 95th percentile. Results: The average "reference value" for blood lead concentrations among Korean adolescents was $2.25{\mu}g/dL$ ($2.49{\mu}g/dL$ for males, $2.07{\mu}g/dL$ for females), and the geometric mean of the blood lead concentrations was $1.34{\mu}g/dL$. Males had higher blood lead concentrations than females (male, $1.48{\mu}g/dL$; female, $1.19{\mu}g/dL$; P<0.001). Elementary school students had higher blood lead concentrations than junior and senior high school students ($1.44{\mu}g/dL$ vs. $1.31{\mu}g/dL$, P<0.001). Participants living in detached houses had higher blood lead concentrations than those living in apartments (P<0.001) and current smokers had higher concentrations than nonsmokers or participants with secondhand smoke exposure (P<0.05). Additionally, participants with excessive alcohol consumption had higher levels than non-drinkers (P<0.001). Conclusion: This study provides national reference data on blood lead concentrations stratified by demographic and lifestyle factors among Korean adolescents. Further studies are needed to elucidate the relationship between increased lead exposure and demographic factors including type of housing.

헌혈원에서 현재 헌혈원 혈액백에 부착된 바코드를 하나씩 스캔하여 관리하는 것을, 관리의 효율성을 높이고 정확성을 높이기 위해 UHF RFID 혈액관리시스템 BIS(Blood information system)을 구현하였고, 고유전율인 혈액이 들어있는 헌혈용 혈액백 (blood bag)에 부착 가능한 UHF RFID Tag 안테나를 설계하였다. RFID Tag 안테나는 부착된 물체의 전기적인 특성으로 인하여 영향을 받으므로, 고유전율인 혈액에 근접 시 태그 안테나의 임피던스 성분이 변하게 되어 태그의 반사손실 및 대역폭에 영향을 주게 된다. 고유전율에 부착된 일반 태그가 냉장고 안에서 인식률이 20%도 미치지 못한다. 그래서 이러한 영향을 고려하여 일반 다이폴 형태의 태그에 반사판을 사용하여 설계하였다. 반사판이 있을 때와 없을 때, 반사판과 다이폴 태그와의 간격, 다이폴 안테나에 T 매칭 구조의 존재에 따라 임피던스를 조절하여 칩과의 정합 회로를 구성하여 최적화된 태그를 설계 및 제작하였으며 제작된 태그의 특성과 인식거리 패턴을 측정 비교하였다. 또한 본 태그를 사용하여 BIS를 구현하여 혈액관리가 실시간으로 되도록 하였다.

In this study, we investigated the effects of dietary supplementation (n = 40 pigs/treatment) with bamboo powder (0, 1, 2 and 3%) for 38 days. We evaluated growth performance, blood metabolites, and carcass characteristics of fattening pigs and gas emission and microbial populations in pig manure, to obtain data on pork producers for environmental management. We obtained the following results. First, supplementation with increasing amounts of bamboo powder had a significant (P < 0.05) effect on feed intake, feed efficiency, and glucose contents (except for initial and final body weight, weight gain, carcass characteristics, and blood urea nitrogen). In terms of blood metabolites, glucose and blood urea nitrogen tended to decrease with increasing amounts of bamboo powder. Second, the amounts of ammonia, methane, amine, hydrogen sulfide, and acetic acid were reduced by increasing amounts of bamboo powder when compared with the controls (P < 0.05). However, there were no significant differences in pH, propionic acid, iso-butyric acid, butyric acid, iso-valeric acid, and valeric acid among all treatments. The lowest gas emission was observed when 3% bamboo powder was used. Third, supplementation with increasing amounts of bamboo powder tended (P < 0.05) to increase the total number of bacteria, Lactobacillus spp., and yeast, but E. coli, Salmonella spp., and Shigella spp. were not detected in any treatment. In conclusion, the results of this study suggest that supplementation with bamboo powder was effective in reducing gas emission and inhibiting pathogen populations in pig manure by lowering the pH of the manure.

Object : In the present study, we investigated the obesity and blood parameters between Qi-deficiency and Fire/Heat pattern identification/syndrome differentiation (PI/SD) in acute stroke patients. Materials and Methods : A total of 391 stroke patients within 7 days after onset were consecutively recruited from 12 hospitals across South Korea from Nov. 1st, 2006 to Jun. 31st, 2009. They were diagnosed as Fire/Heat or Qi-deficiency among five PI/SD subtypes by two independent stroke experts. We investigated the differences of obesity and blood characteristics between Fire/Heat and Qi-deficiency by statistical analyses. Results : In male subjects, obesity was significantly associated with Fire/Heat PI/SD. The averaged mean BMI ($24.13kg/m^2$) and waist circumference(89.34cm) of the Fire/Heat group were higher than those of the Qi-deficiency group ($22.60kg/m^2$ and 83.43 cm, respectively). The number of obese patients was larger in the Fire/Heat group than in the Qi-deficiency group (p = 0.001). Hyperlipidemia was also related with Fire/Heat. However, obesity was not associated with PI/SD in female subjects where the number of hyperlipidemic patients was higher in the Qi-deficiency group. Among blood parameters, the levels of triglycerides and fasting blood sugar were higher in the Fire/Heat group compared with the Qi-deficiency group in male subjects. However, total cholesterol of the Qi-deficiency group was higher than in the Fire/Heat group among female subjects. Conclusion : This study shows that obesity and hyperlipidemia are significantly difference between Qi-deficiency and Fire/Heat. We suggests that PI/SD may be associated with clinical characteristics and large population study between PI/SD and clinical characteristics including blood parameters are needed.

We examined the relationship between the basic characteristics and types of leisure activities according to blood types. It was based on questionnaires answered by 441 collegians in public health departments and 282 in non-public health departments in Daegu Health College in March, 2005. The frequency of leisure activity of once or twice a week or less during weekdays was the most common.: The most common frequencies for all blood types were between 1 and 2 hours on weekdays and between 3 and 5 hours on the weekends or holidays. As far as the type of leisure activities during the weekdays was concerned, in the case of public health departments, blood type A was interested in computer games and then watching TV, blood type B was attracted to watching TV and listening to music, blood type AB was into watching TV, computer games, and listening to music, and blood type O was keen on watching TV and computer games in that order. The type of leisure activity according to blood types in public health departments was shown to be significantly different (p<0.05). The type of future leisure activity was shown to be significantly different between public health departments and non-public health departments (p<0.05). The type of present leisure activity preferred by collegians, according to the study, was entertainment such as computer games for most blood types. The type of future leisure activities was related to the field of tourism and sports. The collegians need to have more advanced and positive leisure activities.
