  • Background: Ginsenoside Rg3 and arginine-fructose (Arg-Fru) are known as the hypotensive compounds of Panax ginseng; however, their efficacy on antihypertension has not been reported yet to our best knowledge. Thus, hypotensive components-enriched fraction of red ginseng (HCEF-RG) was prepared from fine root concentrate (FR) and their antihypertensive effects were investigated in spontaneously hypertensive rats (SHR). Methods: Male SHRs were divided into six groups: control (Wistar Kyoto, SHR); FR 500; FR 1,000; HCEF-RG 500; and HCEF-RG 1,000; samples (mg/kg body weight) were orally administered every day for 8 wk. Blood pressure was monitored at 1 wk, 2 wk, 3 wk, 4 wk, 6 wk, and 8 wk by tail cuff method. At 8 wk after samples administration, mice were killed for the measurement of renin activity (RA), angiotensin-I converting enzyme inhibition, angiotensin II, and nitric oxide (NO) levels in plasma. Results: HCEF-RG with four-fold more Rg3 and 24-fold more Arg-Fru contents was successfully prepared from reacted mixtures of FR and persimmon vinegar (12 times against FR, v/v) at $80^{\circ}C$ for 18 h. Both FR 1,000 and HCEF-RG 1,000 showed lowered systolic blood pressure than SHR control group and HCEF-RG 1,000 group exhibited a significant decrease in diastolic blood pressure. RA was significantly lowered in all treated groups, while angiotensin II did not affect by FR and HCEF-RG treatment. However, angiotensin-I converting enzyme inhibition and NO in FR 1,000 and HCEF-RG 1,000 were significantly increased compared with SHR control group. Conclusion: HCEF-RG is more effective and useful for alleviating hypertension than FR, implying the health benefit of Rg3 and Arg-Fru.

  • Typical lebvels of heavy metal exposure for humans may be attributed to four components in the environment ; food, inhaled air, various types of dust, and drinking water. To assess the health risk of lead, it is necessary to estimate the blood lead levels in the populations of concern under various air lead concentrations. The blood lead levels of the population in Seoul and Yeoju are estimated by Biokinetic model for the risk assessment in this study. The differences in blood lead levels between areas of different land use are not dominant but some differences show among different age groups and sex. Blood lead levels of the population show log normal distribution. The geometric standard deviation values of blood lead levels are in the range of 1.25 ~ 1.39, it is somewhat smaller than the values in the general U.S pollution which are determined to be from 1.31 to 1.41 by the U.S. EPA.

  • In order to investigate the effect of 'Whangryonhaedok-Tang' on the anti-inflammatory, ileum of mice, blood pressure, blood glucose, total cholesterol and antibacterial activity, those pharmacological actions were conducted. The results of this studies were summarized as follows; Rat hind paw edema induced by acetic acid was inhibited. In mice, tone of intestinal smooth muscle was suppressed with the treatment of sample and intestinal contractions induced by $BaCl_2$ was inhibited. Hypertensive effect was not observed in rabbits but was observed by the water extract of 'Whangryonhaedok-Tang' excluded Phellodendri Cortex in rabbits. The increased blood glucose levels in alloxandiabetic rabbits were significantly decreased by the oral administration of the sample I after 6 days. The total cholesterol levels in alloxan-induced rabbits were significantly decreased by the oral administration of the sample I after 9 days. Antibacterial activity was observed. In addition, we thought the pharmacological actions were significantly noted by the sample III (Methanol soluble fraction) because of the purification of effective components.

  • Objectives: This study aimed to analyze the relationship between metabolic syndrome and cataract in a middle-aged men over the age of 40's by using the data from the 5th Korean National Health and Nutrition Examination Survey(2010~2012). Methods: The subjects for the analysis were comprised of 5,808 patients who were at least 40 years or more with metabolic syndrome and cataract. The comparison between the metabolic syndrome and ophthalmic diseases according to the health demographic characteristics, health behavior and health conditions was analyzed with ${\chi}^2-test$. The complex samples logistic regression analysis was used to calculate the odds ratio of cataract according to the health demographic characteristics, health behavior and health conditions and the combination of the comprising factors of the metabolic syndrome. Results: After controlling the confounding factors, the odds ratio of cataract in the metabolic syndrome group was OR 1.30, which was significantly high (p<0.01). Furthermore, the odds ratio of cataract was significantly high in the case of males, as the age increased, educational level decreased, with exercising habits of less than 3 days a week, sun exposure of at least 5 hours, with hypertension and diabetes (p<0.01). The results of analyzing the odds ratio for the occurrence of cataract with the components of metabolic syndrome were OR 1.36 (concurrent high fasting blood glucose, high triglycerides, low HDL cholesterol), OR 1.63 (concurrent high fasting blood glucose, high triglycerides, high waist circumference) and OR 1.33 (high triglycerides, low HDL cholesterol, high waist circumference), which showed significantly high odds ratio for cataract occurrence (p<0.05). Conclusions: We come to know that the relation between metabolic syndrome and components are associate with cataract. Therefore the thorough management of metabolic syndrome and components is needed to prevent cataract.

  • Since 1982, female agricultural workers are populous than male in Korea. Previous study was suggested that female workers are more sensitive to the agricultural medicine poisoning than male. This study was conducted with the aim of evaluating the impact on plasma components and nutrient intakes in female agricultural workers by the use of pesticides. Data were obtained from 44 females residing in Wonjoo, Kangwon-do area. Analysis for the general characteristics, nutrient intakes, and plasma components of the subjects were performed by physical examination, 24-hour recall method and venous blood sampling. They were divided into 3 groups according to the degree of the pesticide use: 8 in none(Non-expose group), 14 in low(<4/yr)(Low-expose group), and 22 in high$({\geq}4/yr)$(High-expose group). The results are summarized as follows. Serum glucose, SGOT, SGPT, triglyceride, HDL-cholesterol did not correlated with pesticide use and were not different among the groups. But serum total cholesterol was higher in pesticide use group. With increasing the number of pesticide use times, leukocyte count was tended to increased. Eighty two percent of the subjects were hemoglobin less than or equal to 12g/dl. Hematocrit, MCV, MCH, MCHC, serum Fe, Serum ferritin belonged to normal range and did not correlated with pesticide use. Intake of energy, Fe, vitamin $B_2$ were lower than RDA. Fe, K, and vitamin A intake were higher in don't use group than the other groups. There are not many differences according to using the pesticide in anthropometric measurements, nutrient intakes, and blood components, except for serum total cholesterol level and some nutrients intake. But these results suggest the need the systemic researches about the effects the pesticide using on nutritional status in Korean agricultural workers.

  • This study was attempted to investigate the possible association of osteoarthritis with the metabolic syndrome (MetS) and its components in Korean adults based on the Korean National Health and Nutrition Examination Survey (KNHANES). The prevalence of MetS was significantly increased in OA group in women. To investigate the association between the components for MetS and osteoarthritis, we analyzed the mean values of 5 components of MetS, waist circumference (WC), triglyceride (TG), HDL-cholesterol, systolic blood pressure, and fasting plasma glucose in normal and OA group. In women, WC, TG, HDL, and systolic blood pressure were associated with the development of OA. Moreover, accumulation of components of MetS was significantly related to the prevalence of OA in Korean men and women. These data suggest that MetS might be a novel risk factor for OA and MetS should be taken into account in the prevention and treatment of OA for Korean adults as well.

  • Orthostatic hypotension (OH) is associated with symptoms including headache, dizziness, and syncope. The incidence of OH increases with age. Attenuation of the vestibulosympathetic reflex (VSR) is also associated with an increased incidence of OH. In order to understand the pathophysiology of OH, we investigated the physiological characteristics of the VSR in the disorder. We applied sodium nitroprusside (SNP) to conscious rats with sinoaortic denervation in order to induce hypotension. Expression of pERK in the intermediolateral cell column (IMC) of the T4~7 thoracic spinal regions, blood epinephrine levels, and blood pressure were evaluated following the administration of glutamate and/or SNP. SNP-induced hypotension led to increased pERK expression in the medial vestibular nucleus (MVN), rostral ventrolateral medullary nucleus (RVLM) and the IMC, as well as increased blood epinephrine levels. We co-administered either a glutamate receptor agonist or a glutamate receptor antagonist to the MVN or the RVLM. The administration of the glutamate receptor agonists, AMPA or NMDA, to the MVN or RVLM led to elevated blood pressure, increased pERK expression in the IMC, and increased blood epinephrine levels. Administration of the glutamate receptor antagonists, CNQX or MK801, to the MVN or RVLM attenuated the increased pERK expression and blood epinephrine levels caused by SNP-induced hypotension. These results suggest that two components of the pathway which maintains blood pressure are involved in the VSR induced by SNP. These are the neurogenic control of blood pressure via the RVLM and the humoral control of blood pressure via epinephrine release from the adrenal medulla.

  • A reduced NaCl intake for the general population of the world has been recommended to reduce the overall blood pressure level and hence to reduce the overall incidence of cardiovascular disease. A high NaCl diet convincingly contributes to elevated arterial pressure in humans and animal models of hypertension. Among individuals there is considerable variability of blood pressure responsiveness to NaCl intake. In normotensive as well as hypertensive subjects, blood pressure can be judged to be salt sensitivity (SS) when observed to vary directly and substantially with the net intake of NaCl. The prevalence of SS in normotensive adults in the U.S. ranges from 15% to 42% and in hypertensive adults from 28% to 74%. SS is a risk factor for hypertension and may be an important marker in the identification of children for hypertension prevention programs. High NaCl intakes produce expansion of the extracellular fluid volume and thus increase blood pressure. Nonchloride salts of sodium does not expand the extracellular fluid volume and does not alter blood pressure. Blood pressure response to NaCl may be modified by other components of the diet. Low dietary intakes of potassium or calcium augment NaCl-induced increases of blood pressure. Conversely, high dietary intakes of potassium or calcium attenuate NaCl-induced hypertension. A greater intakes of potassium or calcium may prevent or delay the occurrence of hypertension. SS occurs when dietary potassium is even marginally deficient but is dose-dependently suppressed when dietary potassium is increased within its normal range. Orally administered KHCO$_3$, abundant in fruits and vegetates, but not KCl has a calcium-retaining effect which may contributed to its reversal of pressor effect of dietary NaCl. Since nutrients other than NaCl also affect blood pressure levels, a reduced NaCl intake should be only one component of a nutritional strategy to lower blood pressure.

  • In the classic point of view, it has well known that the tangle is the mineral source, especially iodide. However, there are few reports that the tangle can be used the high-protein source. With the consideration whether the tangle can be used as a protein source as well as one of the foodstuff or not, this studies is done by animal experiment. The Albino rats to be examined were fed on the basal diet (Table 1) and the others including the polished tangle by weight 2%, 3%, 4% and 5%, as experimental diets, for 4 weeks, respectively. The weight gain(Fig. 1), total amount of diet intake (Fig. 2), total water intake(Fig. 3), feed efficiency ratio (Fig. 4) and protein efficiency ratio (Fig. 5) was measured by each week, respectively. In addition, organ weight (Fig. 6) and blood study (Fig. 7, Fig. 8) was also analyzed at the end of the experiment. As the results of this study, growth rate, that is, weight gain, feed efficiency ratio and protein efficiency ratio in all experimental groups increased more than those of the control group. Moreover, it was also found that weight gain, feed efficiency ratio, protein efficiency ratio by feeding on the 2 percent tangle group was higher than the corresponding values of all experimental groups. However, feed intake and total water gain were the most by feeding on the 5% tangle group. This result may be interpreted to show that the total content of sodium includes more than enough in the feed intakes. To obtain further information concerning the effect of the tangle-dietary conditions on the growth rate of Albino rats, it was measured the organ weight. In the adrenal and spleen, the total weight by feeding on the all experimental groups were decreased more than that in the case of the control group. In the other hand, in the liver the weight by feeding on the high concentration groups (4%, 5% tangle diets) were not higher than the control group, while in the case of the low concentration groups (2%, 3% tangle diets) were higher than that of the control group. When it was observed the blood components, total protein, hemoglobin, sodium, potassium, white blood cell and red blood cell of rats, the content of white blood cell by feeding on all experimental groups were lower than that by feeding on the control group, but it was also clear that in the other components except white blood cell in blood the contents by feeding on all experimental groups were similar to that in the case of the control groups. However, in the 5% tangle group, the content of sodium was the lowest of all experimental groups, where as the content of potassium was the highest of all experimental groups.

  • As a test for diagnosing fatty liver, recently, ultrasound and blood exam are being performed simultaneously. In particular, in the case of high-sensitivity C-reactive protein in blood exam, it is used as an index indicating the level of inflammation in various parts of the body as well as cardiovascular diseases. Thus, this study was conducted to analyze the association between metabolic syndrome components, liver function, and high-sensitivity C-reactive protein levels according to the degree of nonalcoholic fatty liver, and use it as a clinical indicator for fatty liver diagnosis. Metabolic syndrome components, liver function and high-sensitivity C-reactive protein blood test values analyzed from 1,139 men and women over 20 years of age with nonalcoholic fatty liver in abdominal ultrasonography from March 2021 to August 2021 at the Korea Association of Health Promotion, Gwangju-Jeonnam Branch. Analyzed for all men and women, the blood test values for subjects with mild fatty liver were AST 30 U/L, ALT 32.1 U/L, γ-GTP 41.2 IU/L, and hs-CRP 0.14 mg/dL. These values were lower than the blood test values of subjects with moderate fatty liver (AST 38 U/L, ALT 47.6 U/L, γ-GTP 54.9 IU/L, hs-CRP 0.22 mg/dL) and was statistically significant (p<0.001). In this case of high-sensitivity C-reactive protein test, it is statistically significant, showing higher values in Subjects with moderate fatty liver than Subjects with mild fatty liver. thus, it is considered that hs-CRP can be used as clinical data for the prevention and management of fatty liver.
