  • This study was conducted to identify Babesia sp. strain isolated from the imported beef cattle, Aberdeen-angus heifers, in J farm of Jangsu Prefecture, Cheon-buk Province of Korea, morphologically, etiologically and serologically. Babesia sp. strain was purely isolated through the serial blood passages of three generations against splenectomized calves and one generation of blood passage against non-splenectomized calf(intact calf) by inhibiting the appearance of Theileria sergenti in the blood stream by means of injection of 20% oil pamaquine intramuscularly. In the splenectomized calves, the parasite multiplied markedly in blood stream soon after inoculation and parasitaemia was much severe. An elevated body temperature, anorexia, severe anaemia and icterus were observed clinically. Of three splenectomized calves, two were affected with haemoglobinuria and died. But in the non-splenectomized calf the clinical signs and parasitaemia were very mild. The means of the incubation period, the highest parasitaemia, the highest body temperature and the lowest PCV were 3.5 days, 41.1%, ${42^{\circ}C}$ and 9%, respectively, in the splenectomized calves. In calf erythrocytes Babesia sp. protozoa were polymorphic showing the round, oval, ameboid, piriform and paired piriform etc. The sizes of protozoa were $2.51{\sim}3.91{\times}1.32{\sim}2.19{{\mu}m}$ ($3.20{\times}1.60{\mu}m$). Serologically the isolated Babesia sp. were compared with other parasites, B. ovata, B. bigemina, B. bovis, T. sergenti, A. marginale and A. centrale by using the complement fixation(CF) test. As a result, the antibody titer between the homologous species were high. It was two tubes or more in the CF test. From the results obtained above the pure isolated Babesia species was identical with Babesia ovata Minami and Ishihara, 1980.

  • To evaluate the effect of lead biomarkers including bone lead on neurobehavioral test in retired lead workers, 131 retired lead workers without any occupational exposure to organic solvent, mercury and arsenic were agreed to participate this study. For the control subjects 56 non-occupationally lead exposed subjects were recruited from same area of retired lead workers with consideration of demographic characteristics. The mean levels of blood and bone lead of retired lead workers were significantly higher than control group and there were significant correlation among other lead biomarkers. Compared with controls without occupational lead exposure, lead exposured subjects had worse performance on 10 tests out of 12 neurobehavioral tests, but only two tests(Purdue pegboard nondominant and both hand) showed statistical significance of differences. In multiple linear regression analysis of neurobehavioral tests with lead biomarkers and demographic and lifestyle variables, age was associated negatively with 11 neurobehavioral tests, whereas log-transformed ZPP was associated with Purdue pegboard(both hand) and Santa Ana manual dexterity(non-dominant hand). On the other hand, tibia lead was associated Pursuit aiming test(correct) and Purdue pegboard(dominant hand) and calcaneal lead was associated with Purdue pegboard(dominant hand). This study confirmed that among all relevant variables age was most significantly associated with the poor performance of neurobehavioral tests. The blood lead did not have any significant association with neurobehavioral tests, but tibia and calcaneal bone lead and blood ZPP showed significant association with a few tests even after more than mean 9 years from their retirements.

  • This study was performed to find and compare the characteristics of dietary factors and obesity indices on serum lipid profiles using 407 healthy adult males that had physical examinations conducted at the general hospital located in Suwon. The subjects were divided 56.3% for the normal group, 16.7% for TG, 14.5% for TC and 12.5% for TC TG group, respectively. When comparing the blood lipid profiles to normal group, TC group was high in both total cholesterol and LDL-cholesterol, TG group was high in triglyceride and low in HDL-cholesterol, TC TG group was high in triglyceride, total cholesterol, LDL-cholesterol and low in HDL-cholesterol. In comparison of blood lipid profiles with normal group, among anthropometric factors, body weigh, BMI (Body Mass Index) and WHR (Waist Hip Ratio) showed significant differences. TC group was high in both total cholesterol and LDL-cholesterol, and TG group was high in triglyceride and low in HDL-cholesterol. TC TG group was high in triglyceride, total cholesterol and LDL-cholesterol, and was low in HDL-cholesterol. Body weigh of TG group was significantly higher than that of normal group (p<0.05). BMI and WHR of TG group and TC TG group were significantly higher than those of normal group (p<0.05). Total cholesterol was mainly related to the intake of animal lipids and alcoholic beverage. Serum triglyceride levels were closely related with lipid intake and high BMI in this group. In TC TG group, BMI and WHR were high. As well, serum LDL-cholesterol was high and HDL-cholesterol was low which indicates TC TG group had the most undesirable blood lipid profiles. Therefore, it may be necessary to manage BMI and WHR to prevent hyperlipidemia and obesity for adult males in Suwon.

  • Objectives : The purpose of this study was to analyze the trend of clinical research on quantitative indicators of Mibyeong in traditional chinese medicine(TCM). Method : The journal search was performed using china national knowledge infrastructure(CNKI) database. Our inclusion criteria were as following: TCM clinical researches for quantitative indicators of Mibyeong. Exclusion criteria were as following: non-TCM clinical researches, used intervention methods. Results : Eleven clinical researches were analyzed in this study. Four of these researches classify the Mibyeong as a type of pattern identification(PI) and studied the characteristics of the PI quantitative indicators. Mibyeong diagnosis was done through guidelines and questionnaires, each was used at a similar rate. Quantitative indicators mentioned in the selected researches were blood indices, nailfold capillary, complexion, color of tongue substance and coating, pulse wave diagrams and heart rate variability. Among them, seven researches related to blood indices were the most. Blood indicators include whole-blood viscosity, plasma viscosity, fibrinogen, packed cell volume(Hct), triglycerides, total cholesterol, HDL-C, LDL-C, glucose, BUN/CREA, luteinzing hormone, estradiol, follicle stimulating hormone, IgA, IgG, etc. Conclusions : Based on this results, in combination with western medicine, it seems necessary to try to interpret the Mibyeong in more various ways. Even if the same Mibyeong, it is necessary to identify the index which changes according to the PI or chief complaint, and to set the Mibyeong standard corresponding thereto.

  • The objectives of the present study were to (1) determine the susceptibility of Anopheles sinensis to Korean isolates of Plasmodium vivax, (2) establish a method to collect large quantities of P. vivax sporozoites for use as antigen in seroepidemiological studies, and (3) investigate the characteristics of Korean isolates of P. vivax sporozoites. Females of Anopheles sinensis were collected at non-epidemic area, Seokwha-ri, Cheongwon-gun and Chungcheongbuk-do using tent-trap methods coupled with dry ice. The females were artificially infected with gameiocytes of P. vivax using blood obtained from P vivax malaria patients. Individual mosquitoes were infected using either a parafilm-covered glass feeding apparatus or were allowed to feed on naturally infected volunteers. Mosquitoes were sacrificed between 16 and 18 days post-feeding and an enzyme-linked immunosorbent assay (ELISA) was used to detect sporozoites. Four (33.4%) of 12 mosquitoes, which were fed on naturally infected volunteers directly, were positive for sporozoites. In cases, the mosquitoes allowed to feed on whole blood which were extract from three different patients with heparin treated vacuutainers using a parafilm-covered glass apparatus. Two of 55 (3.6%) were positive which blood sample was maintained at room temperature for 8 hours, 1 of 68 (1.5%) was positive which blood was maintained at $4^{\circ}C$ for 24 hours and 1 of 47 (2.3%) was positive at 4$^{\circ}C$ for 48 hours. The mean number of sporozoites was estimated about 818 (n=8; range of 648-1,056) based on optical density values of ELISA.

  • Objectives : To identify the factors related to awareness, treatment, and control of hypertension in a Gwacheen population. Methods : This study surveyed 1,176 Gwacheon residents older than 40 years, and measured blood pressure using a standardized guideline in 1999. The study subjects were 473 adults (175 males, 295 females) with hypertension defined as a systolic blood pressure $\geq$140 mmHg, diastolic blood pressure $\geq$90 mmHg or reported treatment with antihypertensive medication. Information on awareness, treatment, and control of hypertension, and sociodemographic and health-related factors .was collected through person-to-person interviews with a structured questionnaire. Results : Overall, 252 (53.3%) of hypertensive subjects were aware of their condition, of whom as many as 193 (76.6%) were being treated, and 81 (42.0%) had their blood pressure controlled at the recommended level (<140/90 mmHg). However, of the 473 subjects found to have hypertension, only 40.8% were being treated, and 17.1% were under control. There were no significant differences in the proportions of awareness, treatment, and control of hypertension. In multiple logistic regression models, awareness of hypertension was positively associated with age and family history of hypertension in females. Control of hypertension was also positively associated with haying a partner and marital status in females.. Conclusion : These findings demonstrate that much greater efforts on improving awareness, treatment, and control of hypertension are needed, even in urban community settings, considering related factors such as a9e, family history, and marital status. However, these factors should be further investigated for their causal relationship.

  • Objectives The purpose of this study was to examine the characteristics of diagnostic pattern questionnaire associated with Body Mass Index in premenopausal women. Methods We studied 41 patients visiting Gangdong Kyung Hee University Hospital from 1st April 2011 to 25th May 2011. The subjects were categorized in two groups, overweight & obesity group (n=12) and low weight & normal group (n=29). We studied the difference of diagnostic pattern questionnaire scores between two groups by Independent samples T-test and correlation between diagnostic pattern questionnaire scores of overweight & obesity group by Pearson's correlation coefficient test using SPSS for windows (version 13.0). Results Blood stasis, retention of undigested food, cold pattern scores of overweight & obesity group were non-significantly higher than low weight & normal group. Heat pattern score of overweight & obesity group was significantly higher than low weight & normal group. Cold-heat, phlegm-cold, blood stasis-cold, phlegm-blood stasis, phlegm-retention of undigested food significantly showed positive correlation coefficient in overweight & obesity group. Conclusions The results suggest that obese women tend to show heat pattern. It seems to be that multiple factors such as phlegm, blood stasis, retention of undigested food are causative of obesity.

  • The objective of this study was to determine whether any pretreatment parameters were associated with pharmacological effect or toxicity parameters after vincristine administration and to describe a mathematical model, which explains the interpatient pharmacodynamic variability. The relationship between patient characteristics and vincristine dose and hematological toxicity were evaluated. 68 pediatric and adolescence patients and 107 adults with acute lymphoblastic leukemia were treated with vincristine $1.5mg/m^2/day$ IV and other anticancer drugs as scheduled. Complete blood counts and other blood test results were obtained. The input variables were age, gender, weight, lean body weight (LBW), height, body surface area, vincristine dose and total vincristine dose. The outcome measures were nadir values (white blood cells, absolute neutrophil counts, hemoglobin, and platelets); the absolute decrease, relative decrease, and survival fraction of blood cells. Polynomial regression analysis was carried out to determine the other significant covariates. The variability of $WBC_{nadir}$ was modeled with good precision and accuracy with a two-covariate model. This model should be validated and improved on with further clinical data. We believe that such pharmacodynamic modeling should be explored further to determine its performance and clinical relevance compared with modeling using pharmacokinetic parameter.

  • 본 논문에서는 FSI(Fluid-Structure Interaction)기법을 이용하여 인체 회전의 영향을 고려한 혈류와 혈관벽의 거동을 이해하기 위한 수치해석을 수행하였다. 혈관은 협착률이 50%이고 편심이 없는 형상이며 인체 회전 효과를 묘사하기 위하여 혈관 주축에 대해 2 ~ 6 rps 의 회전을 가하였다. 협착과 축 회전의 영향으로 나선형, 비대칭 유동이 강체와 FSI 모델에서 모두 나타났다. 그러나 FSI 모델에서 혈관벽 움직임의 영향으로 혈류의 주기적, 과도적 차이가 발생했다. 특히 혈관 내 경화반의 진전과 경화반 위험성을 나타내는 대표적인 인자로 알려진 유동 재순환 영역이 감소하였다. 혈관벽의 움직임은 협착과 회전효과와 마찬가지로 유동 재순환 영역의 생성에 영향을 미친다.

  • Objective : One of the unique syndromes in Asian traditional medicine named 'heat entering the blood chamber(熱入血室, HEBC)' first appeared in Shanghanlun(傷寒論) and Jinguiyaolue(金匱要略) written by Zhangzhongjing(張仲景) who is the most famous doctor in ancient China. Method : Through comparison between Huangdineijing(黃帝內經), Shanghanlun(傷寒論), Jinguiyaolue(金匱要略) and other medical texts, the correct meaning, causes and mechanisms of HEBC can be analysed and organized to suggest new view of HEBC in modern society. Result : This syndrome is usually occurred in women during catching cold and menstruation, accompanying alternation of chillness and fever, pseudo-malaria, delirium, raveled chest(結胸), uterine hemorrhage, etc. The main sign of this syndrome, delirium belongs to the category of liver disease and fever in Huangdineijing(黃帝內經) which is a document more early published than Shanghanlun. Although there are still many other comprehensions about what blood chamber is, it could be the same as uterus according to Huangdineijing, it is relevant to the control of menstruation and emotions, and the function of liver and thoroughfare vessel(衝脈). Conclusion : HEBC is a syndrome exclusive to women, caused by their unique physical and psychological characteristics. It's beginning can be found in Huangdineijing, and by Shanghanlun and Jinguiyaolue, its concept as a single disease pattern becomes established. In other words, HEBC is a complex disease related to menstruation and its related hormonal dysfunctions, closely related to PMS, menopausal syndrome of today. Physical symptoms accompanied by psychological anxiety and fear is characteristic of this condition. Therefore gynecological approaches as well as socio-cultural issues related to women in modern society must be adopted when dealing with HEBC.
