Isoimperatorin and Oxypeucedanin isolated from root of Angelica Koreana Max. (Umbelliferae) that is used as "Kang-Whal" a botanical drug, in Korea, Show following general pharmacologic activities. The treatment with Oxypeucedanin on the exercised duodenum of the rabbit increased the motility of it while isoimperatorin shows little effects. But on the exercised heart of the frogs, both components depressed its contractility. Whereas Oxypeucedanin depressed both blood pressure of the carotied artery and respiration of the rabbit, Isoimperatorin tends to increase blood pressure, respiration and the tonus of the muscle of the earth worm. Oxypeucedanin did not affect the tonus of the muscles of the earth worm, but depressed the uterus contraction of the rabbit, which was, on the contrary, increased by Isoimperatorin.

Our purpose was to investigate the effect of a 5-week high-fat diet on the body weight, blood components [triglycerides (TGs), free fatty acids (FFAs), and glucose], and lipoprotein lipase (LPL) mRNA expression in the skeletal muscles of rats. Body weight increased overtime in experimental and control groups without significant differences. In terms of the blood components, the density of TG was significantly lower in the high-fat diet group compared to the control, whereas FFA and glucose levels were similar in the two groups. Although the levels of glyceraldehyde 3-phosphate dehydrogenase(GAPDH) mRNA expression were similar between the groups, LPL mRNA expression was significantly higher in the high-fat diet group than that in the control group. The results of this study suggest that a high-fat diet enhances LPL mRNA expression, as well as possibly increases fat metabolism. For a better understanding of the relationship between diet patterns and fat metabolism, further analysis of genes related to the fat metabolism is warranted.

The purpose of this study was to investigate the effect of food habits on blood components level(blood glucose, uric acid, hemoglobin, some lipids levels) and health condition in Taejon. The study was conducted with 250 subjects (male 130, female120) who visited in a general hospital from May to June in 1997. Questionaires were used for food habits. The data were analyzed by using $x^2$-test, t-test, ANOVA and multiple range test. Results were summerized s follow : mean of Broca Index were 110.0 $\pm$13.7% in male, 110.6$\pm$16.6% in female. Mean values of systolic blood pressure and diastolic blood pressure were 130.9$\pm$17.6mmHg, 76.2$\pm$12.6mmHg, respectively. The systolic blood pressure was significantly higher in man than woman, Mean serum total cholesterol, LDL-cholesterol, and HDL-cholesterol and triglyceride levels were 202.8$\pm$40.2, 121.1$\pm$35.5, 50.3$\pm$12.9, 157.1$\pm$112.6mg/dl, respectively. Triglyceride level was significantly higher in man than woman. But HDL-cholesterol was significantly lower in man than woman. And also, the value of LPH and AI were higher in man. So Man has more risk of atherogenesis than woman. Mean values of blood sugar, uric acid and hemoglobin was 102.7$\pm$1.36mg/dl and 14.1$\pm$1.56g/dl were higher in man than woman except blood sugar. Food habit of woman were better than it of man. The levels of education and income did not affect to food habit score. The most problem of habits were intake of salty food and lack of exercise. The intake of nutrients were higher as food habit score was higher. Intakes of energy, Ca, vitamin A and vitamin $B^1$ were lower than RDA's of nutrients in bad food habit group. This result did not show that blood components level and health condition were significantly different by food habits. But Broca Index and triglyceride levels were higher in bad food habit group than other groups, but not statistically significant. By this result, it is more needed food habit education to man and young people. The education of food habits will include the real methods of weight control, low intake of salt and exercise to bad food habit group.

The major function of immune system is to protect infections. The immune systems are composed of innate and adaptive immunity. In adaptive immunity, the cellular and humoral components interact each other. Neonates and infants are infected frequently, because immune systems are naive and easy to expose to infectious agents. The complete history and physical examination is essential to evaluate the child with recurrent infections. The environmental risk factors of recurrent infections are day care center, cigarette smoke, and air pollution. The underlying diseases such as immunodeficiency, autoimmune diseases, allergy, and disorders of anatomy or physiology increase the susceptibility to infections. In immunodeficiency, infections are characterized by severe, chronic, recurrent, and unusual microbial agents infection. The defects of antibody production are susceptible to sinopulmonary bacterial infections. T cells defects are vulerable to numerous organisms such as virus, fungi, bacteria and etc. The screening tests for immune functions are the quantitative and qualitative measurements of each immune components. A complete blood count with white blood cell, differential, and platelet provide quantitative informations of immune components. Total complement and immunoglobulin levels represent the humoral component. Antibody levels of previously injected vaccines also provide informations of the antigen specific antibody immune responses. T cell and subsets count is quantitative measurement of cell mediated immunity. Delayed hypersensitivity skin test is a crude measurement of T cell function. The long term outcome of children with recurrent infections is completely dependent on the underlying diseases, the initial time of diagnosis and therapy, continued management, and genetic counscelling.

We explored how changes in blood vessel compliance affected the systolic rise time (SRT) of the maximum blood pressure (BP) peak wave and the diastolic fall time (DFT) of the minimal BP peak wave, compared to photoplethysmograpic (PPG) parameters, using a two-compartment, second-order, arterial Windkessel model. We employed earlier two-compartment Windkessel models and the components thereof to construct equivalent blood vessel circuits, and reproduced BP waveforms using PSpice technology. The SRT and DFT values were obtained via circuit simulation, considering variations in compliance (the dominant influence on blood vessel parameters attributable to BP changes). And then performed regression analysis to identify how compliance affected the SRT and DFT. We compared the SRTs and DFTs of BP waves to the PPG values by reference to BP changes in each subject. We confirmed that the time-shift propensities of BP waves and the PPG data were highly consistent. However, the time shifts differed significantly among subjects. These simulation and experimental results allowed us to construct an initial trend curve of individual BP peak time (measured via wrist PPG evaluations at three arm positions) that facilitated accurate individual BP estimations.

The influences of acute respiratory and metabolic acid-base disturbances on the carotid, renal and coronary blood flow were measured in dogs. Respiratory acidosis was induced by artificial respiration with 8% CO2 -02 gas mixture and respiratory alkalosis was induced by hyperventilation under the control of respirator. Metabolic acidosis and metabolic alkalosis were induced by intravenous infusion of 0.3N hydrochloric acid and 0.6M sodium bicarbonate solution. To observe the effect of hyperkalemia, isotonic potassium chloride solution was infused. CVI electromagnetic flowmeter probes were placed on the left common carotid artery, left renal artery and left circumflex coronary artery. Each flow was recorded on polygraph. 1. The carotid blood flow showed rapid showed rapid and marked increase in acute respiratory acidosis. Even in the cases when arterial blood pressure was lowered during the state of respiratory acidosis, carotid blood flow increased. By the infusion of hydrochloric acid, carotid blood flow increased slowly and returned to the previous label after discontinuation of the infusion. Carotid blood flow also increased by the infusion of large amount of sodium bicarbonate, but it might be the combined effect of expansion of extracellular fluid and compensatory elevation of carbon dioxide tension. 2.The renal blood flow remained unchanged during the acute acid-base disturbances, suggesting effective autoregulation. Renal blood flow, however, increased very slowly when the infusion of potassium chloride continued for a long period. 3.Although less marked than the carotid blood flow, the coronary blood flow increased in the acute respiratory and metabolic acidosis. In asphyxiated condition, coronary blood flow increased most markedly and this might be the combined effect of hypoxia, hypercapnea, and lowering of pH. In summary, the carotid blowflow showed more marked change in the acute respiratory and metabolic acidosis than the renal and coronary blood flow. Respiratory and metabolic components of acid-base disturbances may influence the local blood flow concomitantly, there being more differences in the individual responses, but respiratory component manifested more rapid and marked effect than metabolic component.

Minerals are individual of the components of foods and are not produced in the body but essential for best possible health. Several essential metals are vital for the appropriate performance of various enzymes, transcriptional factors and proteins that are essential in various biochemical paths. Metals like zinc (Zn), magnesium (Mg), and manganese (Mn) are cofactors of hundreds of enzymes. Zn is involved in the synthesis and secretion of insulin from the pancreatic ${\beta}-cells$. Chromium (Cr) increases the insulin receptors activity on target tissues, mainly in muscle cells. Insulin hormone is required to maintain the blood glucose amount in normal range. Continual increase of blood serum glucose level leads to marked chronic hyperglycemia or diabetes mellitus. Deficiency of insulin or its resistance, blood glucose level exceeds the upper limit of the common range of 126 mg/dl. Poor glucose control and diabetes changes the levels of essential trace elements such as Zn, Mg, Mn, Cr, iron etc. by rising urinary excretion and their related decrease in the blood. The aim of this article to discusses the important roles of essential trace elements in particular perspective of type 2 diabetes.

Total saponins and ether extracts of red and white ginseng were obtained and their effects on blood pressure in cat and their histamine liberating activities in rabbits were measured. 1) Ether extract of red ginseng showed a transient hypotensive effect and subsequently showed a remarkable and persistent hypotensive effect, whereas other three fractions, such as saponin fractions of red and white ginseng and ether extract of white ginseng showed only a initial transient hypotensive effects. 2) Histamine levels liberated into blood after administration of each fractions measured by the bioassay with guinea pig ileum. Ether extract of red ginseng immediately increased histamine contents in plasma but the histamine levels decreased to normal level within 10min in spite of decreased blood pressure was sustained. Although white ginseng saponin lowered blood pressure immediately when it is administered, histamine release was observed after 10min. The results suggest that hypotensive effects of ginseng seems to have no correlation with the histamine liberating activity. Ginseng appears to show hypotensive effect via some other mechanisms.
