The dried root of Angelica gigas (A. gigas) has been traditionally used as an oriental medicine, which is known to improve blood circulation and blood stasis. In the present study, leaves and stalks of A. gigas were used to investigate their effects on the innate immunity. The extracts were prepared from leaves and stalks of A. gigas and were fed to mice. The numbers of blood cells, total WBCs, neutrophils, lymphocytes, eosinophils and basophils were increased by 50% in mice fed with leaves extract of A. gigas compared to control mice. However, the numbers of blood cells were decreased when treated with stalks extract of A. gigas. The level of cholesterol and triglyceride in serum was markedly reduced in both mice group fed with leaves extract and stalks extract of A. gigas compared to control group (P<0.01). There was no significant change in the level of albumin, total protein, phosphate and calcium in serum. Activity of cationic peptide was found to be diffused in the testicles of mice fed with leaves extract of A. gigas compared to control group, which might be due to increased lysozyme in testicle. The lysoplate assay and immunohistochemistry assay suggest that the extract of leaves and stalks of A. gigas are immunogenic, but the effects might be related with acquired immune response rather than innate immunity.

A biomarker is needed to monitor and manage the health of pigs from heat stress (HS). Therefore, we investigated the effects of HS on growth performance, nutrient digestibility, and blood profiles in finishing pigs. A total of 12 finishing pigs (n = 12) were raised in thermal neutral (TN; 25℃) conditions for a 3-d adaptation period. After the adaption, 6 pigs were exposed to HS at 33℃ (HS33) for 5 d. The pigs were fed the same diet based on corn and soybean meal. Chromic oxide was added to all the diets at a level of 2 g·kg-1 as an indigestible marker for the determination of the apparent total track digestibility (ATTD) of nutrients and amino acids. Blood samples were collected after the adaptation and heat treatment to verify the blood profiles. The HS33 pigs had a lower (p < 0.01) average daily feed intake (ADFI) and higher (p < 0.05) rectal temperature compared to the TN pigs. However, there was no difference in the ATTD of nutrients and amino acids. The HS33 pigs had reduced (p < 0.05) levels of serum glucose, non-esterified fatty acids (NEFA), total protein, albumin, and calcium compared to the TN pigs. However, the level of total bilirubin was increased (p < 0.05) in the HS pigs. In conclusion, HS reduced the feed intake and had an adverse effect on health. Altered blood profiles as a result of a negative energy balance are expected to be biomarkers of HS in finishing pigs.
The purpose of this study was to investigate the distribution patterns of serum triglyceride and cholesterol levels and the influence of environmental and dietary factors in 201 healthy male subjects. The subjects were found to be 53.7% for the normal, 15.4% for the TC, 17.4% for TG and 13.5% for TC.TG group, respectively. Among general characteristics, smoking significantly affected serum lipid levels of subjects (p < 0.05). Among anthropometric factors, body weight, BMI and PIBW significantly influenced the blood lipid patterns. Body weight of TG group was significantly higher than that of normal group (p < 0.05). BMI and PIBW of TG group and TC.TG group were significantly higher than those of normal group (p < 0.05) . In addition, diastolic blood pressure of TG group was significantly higher than that of normal group (p < 0.05). For the food intake, average intake of fruit was significantly higher in normal group than that of TG group (p < 0.05). For nutrient intake, calcium intake was significantly higher in TC group than those of normal and TC.TG group (p <0.05). Intakes of vitamin $B_2$ and C were significantly higher in TC group than those of in TG group (p < 0.05). Serum HDL-cholesterol level was negatively related to meat, poultry, and their products (p <0.05), but serum total cholesterol level positively related to animal lipids (p < 0.05). The results of this study suggest that it is crucial for maintaining adequate serum lipid levels to reduce smoking, blood pressure and to lose body weight. As far as food intake concerned, fruit intake was important in maintaining serum triglyceride level normal, while animal food intake affected serum total cholesterol level adversely.

This study evaluated the correlation between serum uric acid level and the nutrients adequacy ratio (NAR) using data from the Korea National Health and Nutrition Examination Survey (KNHANES) 2016~2019. This is a cross-sectional study in which 6,579 Korean male adults were divided into quartiles according to their uric acid levels. All analyses were performed with adjusted age. Uric acid decreased as the age increased from the age group 19~29 years to 30~49 years and then to 50~64 years. Interquartile results of serum uric acid levels showed that increases in the serum uric acid levels were associated with decreases in LDL-cholesterol (P<0.01), triglycerides (P<0.001), body weight (P<0.001), waist circumference (P<0.001), body mass index (P<0.001), systolic blood pressure (SBP) (P<0.001), diastolic blood pressure (DBP) (P<0.001). However, uric acid levels decreased with an increase in HDL cholesterol (P<0.001). The analysis of the NARs according to the quartiles of serum uric acid levels in men showed that an increase in serum uric acid levels was associated with a decrease in the NAR levels of dietary fiber (P<0.001), calcium (P<0.001), and folic acid (P<0.001).
This study aimed at investigating correlation of nutrients intake and serum lipids in middle-aged korean male and female workers. One hundred sixty eight(male ;105, female ;63) for adult aged 30-59yr(average age male ;36.5yr, female ;44.5yr) were selected as subjects during 2 months, from April to May, 1996. Nutrients intake status was investigated by questionnaire, 24-hour recall method. Antropometric assessments, serum lipids and blood pressure of the subjects were investigated. The results as follows: 1. Nutrients intake status ; male was superior to female. Vitamin A intakes of 40-49yr group were inferior to other group but amounts of intake were above Korean RDA(recommended dietary allowances), Intakes of calcium and vitamin C of 30-39yr and over 50yr group in female were below Korean RDA. In overweights group of male and underweight group of female, most nutrients intake were increased than other groups. 2. Antropometric assessments ; female was higher than male in BMI (body mass index). All subjects increasingly with age were increased in BMI. 3. Blood components were above normal range in triglyceride in both sexes and all subjects increasingly with age were increased In level of serum lipids and blood pressure, especially in male's forty and in female's fifty were higher than other groups In serum lipids and blood pressure. In overweights group, serum lipids and blood pressure had a significantly($\alpha$=0.05) increasing tendency in both sexes. 4. Serum lipids and connected factors; atherogenic index correlated positively with triglyceride, total-chol(total cholesterol), LDL-chol(low density-lipoprotein cholesterol) and negatively with HDL-chol(high-density-lipoprotein cholesterol) significantly(P<0.001). Systolic blood pressure correlated positively with total-chol and diastolic blood pressure correlated positively with total-chol, LDL-chol significantly(P<0.05). 5. Serum lipids and nutrients intake status: energy correlated positively(P<0.05) with BMI, dietary fiber correlated positively with LDL-chol(P<0.05), calcium correlated positively with triglyceride, atherogenic index and dietary fiber correlated negatively with BMI in male significantly(P<0.05). Triglyceride correlated positively with vitamin C and phosphorus correlated negatively with BMI in female significantly(P<0.05). Above results, in male's forty and in female's fifty were liable to variation in terms of serum lipids and blood pressure. As increasing triglyceride, total-chol, LDL-chol and decreasing HDL-chol Increased atherogenic index that suggest increasing risk of atherosclerosis. But, this point will be considered more subdivided study.
In order to study the compensatory renal function in 6 Korean black goats with 75% reduction in renal mass, some blood chemical values were determined and pathological changes were examined. The results were as follows : 1. BUN level increased significantly from post-operation day 1 through day 30(p<0.01) compared with pre-operation level. Serum creatinine level increased significantly from post-operation day 1 through day 26(p <0.01 ) compared with pre-operation level and remained higher than pre-operation level at day 30(p <0. 05). 2. Serum calcium level increased significantly from post-operation day 4 through day 7(p<0.01) compared with pre-operation level and remained higher than pre-operation level from post-operation day 8 through day 14(p<0.05). Serum phosphorus level decreased at postoperation day 4,5(p<0.05 ) compared with pre-operation level. 3. RBC counts decreased at post-operation day 2. 3, 5. to 30(p<0.05), PCV decreased at post-operation day 2, 3, 5, 7, to 30(p<0.05), hemoglobin level decreased at post-operation day 2, 8, 14, to 30(p<0.05), compared with pre - operation levels, respectively. 4. The ventral half of the right kidney was infarcted by the ligation of ventral branch of right renal artery.

Cancer development and the efficiency of chemotherapy relies on the patients calcium-related pathological status such as hyper- or hypocalcemica. In the present study, we investigated the effect of extracellular cations such as calcium and magnesium on the therapeutic efficacy of antitumor drugs. The analytic parameters used were cellular drug uptake/excretion and the chemosensitivity of the human breast cancer cell lines, MCF7 and MCF7/ADR. Both calcium and magnesium ions decreased the membrane permeability of cancer cells, which was determined bycell size analysis. These divalent ions also lowered the drug uptake and the cytoplasmic levels of rhodamine 123 and adriamycin, suggesting that they might interfere with the diffusion of these drugs by modifying the physical properties of the cytoplasmic membrane. The acute cytotoxicity of adriamycin after a short period of incubation correlated with changes in its cytoplasmic level. Our results indicate that these extracellular cations might play an important role in the therapeutic activities of anticancer drugs in cancer patients. These results also provide insight a new aspect of chemotherapy, because they suggest that the therapeutic dose of anti-cancer drugs should be modified in cancer-bearing patients presenting with abnormal blood calcium levels.
This study investigated the interactions of bone health with several variables such as outdoor activity hours, nutritional status including habitual intake of calcium andvitamin D status in 72 high school girls aged 16-17 yearsattending day classes or night classes. The subjects consisted of 39 day-class students and 33 night-class students. Dietaty nutrient intakes were estimated using the 24-hour recall method. The daily activities of each subject were assessed using an activity questionnaire. Urinary calcium and creatinine excretion were assayed from subjects' 24-hoururine, while 25-OH-vitamin D[25-(OH)-D] and osteocalcin were measured from the subjects' fasting blood. Intake of energy, iron, vitamin A and vitamin C were worse in the night-class students. There was no significant difference in dietary calcium between the subjects in the different class types. Time spent on outdoor activities was significantly less in subjects attending night classes. Urinary calcium excretion of the night-class subjects was significantly higher than that of the day-class subjects (p<0.05). There was no significant difference in serum 25-(OH)-D level according to class type. Serum osteocalcin for night-class subjects was significantly higher than that for day-class subjects (p<0.01). It appeared that the night-class students had poorer dietary habits as well as fewer outdoor activities. Even though the estimated bone health of both groups of subjects appeared to be normal, the overall nutritional intake and duration of outdoor activities appeared to be important for maintaining bone health and lowering the future risk of osteoporosis.
Regional differences between large cities and rural areas are observed in the Korean National Health and Nutrition Examination Survey (KNHANES). This present study was conducted to evaluate the effect of dietary factors on hypertension risk in Korean populations, especially residents of the Chungcheong province which was not in metropolitan area, using KNHANES III. A total of 544 adults aged ${\geq}$ 19 years were placed into either the normotensive or the hypertensive group. Subject characteristics, BMI, blood pressure, and nutrient intakes were compared between the two groups using a chi-square test and t-test. We estimated odds ratios (ORs) using multiple logistic regression, adjusted for energy intake and selected covariates. There were significant differences in age, education level, alcohol consumption, and BMI between the normotensive and hypertensive groups. We found decreased ORs for the medium versus lowest tertile of calcium intake (multivariate OR=0.43, 95% CI: 0.21-0.88), for the highest versus lowest tertile of calcium intake (multivariate OR=0.43, 95% CI: 0.20-0.90) with significant trends in risk (P=0.040), and for the medium versus lowest tertile of potassium intake (multivariate OR=0.43, 95% CI: 0.20-0.89). Subjects with the highest sodium/calcium ratio had a 2.10-fold greater risk of hypertension compared to the subject with the lowest, with significant trends in risk (P=0.002). Adequate calcium and potassium intake should be encouraged and regional differences should be considered in making a healthy plan for hypertension management.
Vitamin D deficiency (VDD) is becoming an epidemic and thereby a global health problem. Further, VDD adversely affects calcium metabolism and skeletal health, and is associated with increased risk of several diseases, e.g., autoimmune diseases, several types of cancers, type 2 diabetes mellitus, cardiovascular diseases, infectious diseases, asthma, psoriatic arthritis, and etc. To evaluate the prevalence of VDD in Korea, and then to evaluate the association of several factors with serum 25(OH)D level, the author analyzed the data of 14,456 individuals who were 10 years of age and over from the Fifth Korea National Health and Nutrition Examination Survey 1 & 2 (KNHANES V-1 & 2) conducted by the Korean Centers for Disease Control & Prevention. As a result, among Koreans (age $${\geq_-}$$ 10years), 65.9% of males and 77.7% of females were below optimum blood serum 25(OH)D (20 ng/mL). VDD is more severe in female than in male at all age groups. In addition, the younger generations had less 25(OH)D level than older generations in Korea. The analysis by complex sample general linear model (CSGLM) suggested that blood 25(OH)D concentration was related with gender (p < .001), residence (p = .030), occupation (p < .001), anemia (p < .001) and physical activity (p < .001). In conclusion, VDD is pandemic and it is more severe in younger generations in Korea. Further, from the results by CSGLM, serum 25(OH)D status is closely related with the life style of Koreans.
