Objectives: College is an important time for students to establish their identity as an independent subjects and develop a foundation to maintain a healthy adulthood. However, after female students become college students, their eating habits are likely to become more irregular and they may experience various health problems because of excessive weight control. Therefore, this study was conducted to investigate the dietary behaviors and blood clinical indices of female college students by residence types. Methods: A total of 374 subjects were classified as home group, self-boarding group or boarding group according to residence type. Dietary habits, frequency of food intake, and eating attitudes were examined through questionnaires and anthropometric measurements and blood clinical indices were analyzed. Results: The meal most frequently skipped by female college students was breakfast, and the frequency of skipping breakfast was significantly lower in the home group than other groups. Most college students recognized that their eating habits had worsened since becoming college students, with the self-boarding group in particular feeling that their eating habits changed negatively. The consumption frequencies of protein foods, fruits, dairy products, seaweed, and fatty meats were significantly lower in the self-boarding group than other groups. The home group ate food cut into smaller pieces, while the self-boarding group tried new and rich foods. Residence types did not affect blood clinical indices. Conclusions: The self-boarding group had inadequate dietary habits compared to the home group. Although residence type did not affect the blood clinical indices, the students still had poor dietary habits. Therefore, proper nutrition education is needed to improve the nutritional status of college students, especially those that self-board.

Recently, a lot of epidemiological studies revealed that low HDL-cholesterol level was a better predictor of risk for coronary heart disease than total cholesterol. This study investigated the anthropometric parameters, clinical blood indices, and dietary factors influencing serum HDL-cholesterol level by using a cross-sectional study for Korean female college students. The subjects were 94 female college students. They were divided into three groups according to their serum HDL-cholesterol levels, low HDL-cholesterol (<50 mg/dL, n=20), medium HDL-cholesterol (50 $\leq$, < 60 mg/dL, n=39) high serum HDL-cholesterol groups (60 $\leq$ mg/dL, n = 35). This study examined their demographic data and dietary intake throughout a questionnaire. Clinical blood indices were measured using an automatic blood chemistry analyzer (Selectra E), after 12 hours of fasting. BMI, body weight, fat mass, and waist circumferences were significantly increased according to low serum HDL-cholesterol levels. Serum lipid analysis showed a significantly higher level of TG, LDL-/HDL-Ratio, atherogenic index in the low HDL-cholesterol group. Serum levels of GPT, uric acid and alkaline phosphatase in the low HDL-cholesterol group were significantly higher than in the other group. The average consumption of energy was 1627 kcal and 77.76% of estimated energy requirement (EER). The mean ratio of calories from carbohydrate: protein: fat was 57:15:28. The low HDL-cholesterol group was significantly higher than the other groups in eggs, fat and oils consumption. Interestingly, milk and diary products consumption of low HDL-cholesterol group was half (p < 0.05) of those of the other groups. In conclusion, serum HDL-cholesterol levels appeared to be decreased by increasing BMI, fat mass, waist circumference, and serum TG level. In addition, some dietary factors seemed to be related to serum HDL-cholesterol levels. However, further research is needed to elucidate the exact relationship between serum HDL-cholesterol level and dietary factors.

Objectives: Normal weight obesity (NWO) is defined as excessive body fat in the context of a normal body mass index (BMI). This condition carries a greater risk of developing noncommunicable chronic disease and has been associated with early inflammation. This study was conducted to compare the anthropometric measurements, eating behaviors, and blood clinical indices among four groups: underweight, normal, normal weight obesity and obesity. Methods: The subjects included 215 female college students. A questionnaire was administered regarding general characteristics, dietary behaviors, food consumption frequency. Anthropometric measurements and blood clinical indices were also investigated. Results: The average BMI, body fat percentage, waist circumference, fat-free mass, and muscle mass were highest in the obesity group (p<0.05). Most subjects had tried to lose weight and perceived that their health was worse than before they became college students. The ratio of students in the NWO group who thought their health was very poor was significantly higher than in the other three groups (p<0.05). The obesity and NWO groups seemed to eat more and their eating speed was significantly faster than the other groups (p<0.001). The consumption frequency of caffeinated beverages was significantly higher in the NWO group than in the other three groups (p<0.01). WBC was significantly higher in the obesity group (p<0.05). Serum levels of TG and total cholesterol were also significantly higher in the obesity group (p<0.05). Serum GPT was significantly higher in the obesity group (p<0.05) while BUN level was highest in the NWO group (p<0.05). Conclusions: The obesity group showed the most health problems while the NWO group seemed relatively healthy. However, NWO can lead to problems such as metabolic syndrome and cardiovascular disease in later life if poor dietary habits are maintained. Therefore, education in appropriate eating habits is needed for these subjects.

Objectives: Although the number of laboratory workers is constantly increasing every year, few studies have been conducted on the health and nutritional status of these research workers. This study determined the health status of laboratory workers by analyzing their anthropometric indices, dietary life, vitamin D status and blood clinical indices. Methods: The subjects consisted of 100 female laboratory workers. This study investigated their diet, anthropometric indices, vitamin D status and blood clinical indices. The subjects were divided into two groups according to their duration of working in a laboratory (<1 year, $${\geq}_-1year$$). Results: The average age and body mass index (BMI) of subjects were 23.18 years and $21.51kg/m^2$, respectively Those subjects with over 1 year employment ($${\geq}_-1year$$) had a significantly higher waist-hip ratio than that of the subjects with the less than 1 year employment (<1 year). The mean serum vitamin D level of all the subjects was 10.04 ng/mL, which is close to a level of vitamin D deficiency. There was a significantly higher average intake of calories in the over 1 year employment group as compared to that of the less than 1 year employment group. The frequency of eating sweet snacks was significantly higher for the over 1 year employment group. The correlation analysis showed a significant positive correlation between the serum 25-(OH)-vitamin D level and the time of exposure to sunlight, while dietary intake of vitamin D did not show correlation with the serum 25-(OH)-vitamin D level. However, the serum 25-(OH)-vitamin D level was also negatively correlated with both the percentage of body fat and visceral fat. Conclusions: Laboratory workers are a very high risk group in terms of their nutritional status of vitamin D. Therefore, they need greater time of exposure to sunlight as well as increasing their dietary consumption of vitamin D. In addition, it is important for laboratory worker to practice regular and balanced dietary habits in order to maintain a healthy life.

Stellate ganglion block (SGB) is applicated frequently to increase the blood flow and to reduce the pain in head, neck and upper extremity. The effects of SGB are able to be estimated by clinical signs and symptoms of Horner's syndrome, skin warmth, anhydrosis, etc. The effects are also estimated by sympathetic function and the blood flow. Blood flow velocities and pulsatility indices of common carotid,d axillary, brachial and radial artery were measured by Doppler flowmeter after SGB with 1% lidocaine at C6 level. Blood velocities of all arteries were increased and pulsatility indices of all arteries were decreased. This results suggest that SGB increase the blood flow of head and upper extremity and Doppler flowmeter is a good indicator of the effects of SGB.

This study was done to evaluate the health and nutritional status of female college students in Seoul. The subjects were 63 healthy college students aged 20 to 29 years. Their body composition, dietary intakes, clinical blood indices were investigated. Their body composition was determined by means of a multifreqency bioelectrical impedance analysis. Their dietary intake was determined using 3-day record method and their nutrient intake was analyzed by Computer Aided Nutritional analysis program for professional (CAN-pro). Their hemoglobin, hematocrit, red blood cell (RBC), white blood cell (WBC) and mean corpuscular volume (MCV) were determined by semi-automated microcell counter (F-520). Their plasma total cholesterol, TG, and HDL-cholesterol levels were measured using test kits. All data were statistically analyzed by SAS PC package program. Their average consumption of calcium, iron vitamin A, vitamin B2 and niacin were 63.3%, 65.0%, 85.2%, 89.2% and 95.2% of RDA, respectively. The overall mean values of the hematological indices in the female college students were within the normal range. However anemic subjects with hemoglobin (< 12 g/dl) and hematocrit (<36%) accounted for about 20% of the subjects. The mean levels of total cholesterol, HDL-cholesterol and TG were 188.4mg/dl, 69.9mg/dl and 67.4mg/dl, respectively. The percentages of the subjects with plasma total cholesterol level (> 200mg/dl) and LDL-cholesterol (＞130mg/dl) were about 41% and 30.4%, respectively. The data showed a significantly positive correlation between either body fat (%) or BMI and TG. However. there was a significantly negative correlation between either body fat (%) or BMI and HDL-cholesterol. These overall results suggest that it is necessary for college women to be educated regarding consuming more iron and vitamin C and less fat, in order to prevent iron deficiency anemia and/or cardiovascular diseases in later life.

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 objective of this research was to evaluate the relationships of preoperative (Pre-OP) levels of hematological and biochemical indices to perioperative variables in patients that underwent coronary artery bypass graft surgery (CABG). Pre-OP levels of hematological factors [total white blood cells (T-WBC), erythrocytes, hemoglobin, hematocrit, glycohemoglobin A1c (HbA1c), or platelet] were negatively or positively related with biochemical indices [alanine aminotransferase (ALT), bilirubin, glucose, fructosamine, triglyceride, and high density lipoprotein cholesterol (HDL)]. Pre-OP levels of hematological factors and biochemical indices were negatively or positively correlated with echocardiographic variables. Pre-OP level of HbA1c had a relationship with C-reactive protein. Pre-OP levels of aspartate aminotransferase (AST), ALT, HDL, glucose, fructosamine, or blood urea nitrogen (BUN) were positively or negatively associated with Pre-OP levels of cardiac markers (brain natriuretic peptide, troponin-I, creatine kinase isoenzyme 2, or CRP). Pre-OP levels of hematological factors (excepting T-WBC) related with operation time (OPT), postoperative mechanical ventilation time (POMVT), intensive care unit-period (ICU-period) or hospitalization. Pre-OP levels of AST, ALT, bilirubin, triglyceride, HDL, low dwensity lipoprotein, fructosamine, or BUN were positively or negatively correlated with OPT, graft numbers, POMVT, ICU-period or hospitalization. Retrospective this study reveals that Pre-OP levels of hematological and biochemical markers are associated with echocardiographic variables, several cardiac markers and postoperative outcomes, suggesting that Pre-OP levels of hematological and biochemical markers may be useful predictors for the diagnosis and prognosis of coronary artery disease.

Purpose: The purpose of this study was to investigate influences of drinking, smoking, and obesity indices on cardio-cerebrovascular disease risk factors in Korean young men. Methods: The subjects were 234 young men, aged 20 to 39 years. Body mass index (BMI), percent body fat (PBF), body fat mass (kg), and waist hip ratio (WHR) were measured as obesity indices. Systolic blood pressure (SBP), diastolic blood pressure (DBP), fasting blood sugar (FBS), total cholesterol (TC), triglyceride (TG), high-density lipoprotein cholesterol (HDL-C), and low-density lipoprotein cholesterol (LDL-C) were measured as cardio-cerebrovascular disease risk factors. The data were analyzed by t-test, ANOVA, Pearson's correlation coefficient, and multiple regression analysis using SAS 9.4. Results: Statistically significant factors were BMI for SEP; age, degree of drinking, body fat mass for DBP; WHR for TC; WHR and age for TG; age, degree of smoking and PBF for HDL-C; WHR, age and degree of smoking for LDL-C. Conclusion: Factors identified in this study need to be considered in cardio-cerebrovascular disease prevention programs for young men.

We evaluated whether liver markers such as aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP), gamma-glutamyltranspeptidase (GGT), and bilirubin have a relationship with other physiological factors in the normal (n=115) and fatty liver subjects (n=122) and there are differences between the two populations. Body indices were higher in the fatty liver group than in the normal group. Liver markers and blood pressure (BP) were greater in the fatty liver group than in the normal group. AST and ALT levels were positively correlated with body indices in the fatty liver group, but not in the normal group. AST, ALT and GGT levels in the fatty liver group had positive relationship with cardiovascular indices (CI). ALP and bilirubin levels were negatively associated with some of CI. Liver markers were negatively or positively correlated with inflammatory markers, thyroid hormones, or several biochemical markers levels. These findings suggest that abnormal changes in liver markers may be useful tool for diagnosis or prognosis of development of cardiovascular and/or inflammatory diseases as well as metabolic syndrome.
