Cholesterol-lowering effect of pine nut on mice was investigated by examining changes in body weight, feed intake, and triglyceride, total cholesterol, high density liporotein cholesterol (HDL-C), low density lipoprotein cholesterol (LDL-C), and very low density lipoprotein cholesterol (VLDL-C) contents in mice plasma. Changes in body weight and feed intake between pre-designed experimental animal groups fed various contents of cholesterol and pine nut and control group fed basal diet were not significantly different. Food efficiency ratio of experimental groups fed higher than 10% pine nut was significantly higher than that of control group. Apparent differences in atherogenic index representing cholesterol-lowering effect in plasma were not found among all groups fed 0-20% pine nut. Inhibition activities of water and hexane extracts of pine nut on HMG-CoA reductase and cholesterol esterase were examined in vitro. Hexane extract showed 66% inhibition effect on HMG-CoA reductase, whereas none was observed with water extract.

The purpose of this study was to investigate the effect of germinated buckwheat on blood pressure, plasma glucose and lipid levels of spontaneously hypertensive rats(SHR). The male and female SHR were divided into two groups. After feeding the germinated buckwheat diet(50%, w/w) ad libitum for 6 weeks, the weight gain of the germinated buckwheat group in male rats was higher than those of control group. Systolic blood pressure of the germinated buckwheat group in male rats was significantly decreased at 6 weeks by 3%. The fasting glucose levels of the germinated buckwheat group had a tendency to be lower compared with those of the control group. Total cholesterol, HDL-cholesterol and HTR of female SHR fed the germinated buckwheat diet were significantly increased compared to the control diet. Atherogenic index of the germinated buckwheat group was decreased in males(ns) and females(p<0.05) than those of the control group. From these results the germinated buckwheat might be useful for anti-hypertensive and anti-hyperlipidemic agents.

The target controlled infusion(TCI) pump system is a logical approach to the development of improved administration techniques of an intravenous anaesthetic agent. The principle of TCI system is based on an understanding of the pharmacokinetic properties, three or four compartment model. The TCI system is optimal and flexible control of the plasma drug concentration. But the clinical goal is always to achieve a therapeutic drug effect, not a therapeutic concentration. So we developed the algorithm to target the concentration at the site of drug effect rather than the concentration in the plasma. If impulse drug is inputted into body, the decline of plasma concentration with time is shown, resulting in the expression of the differential equation. Therefore, we must reformulate our three-compartment model as four-compartment model with the effect compartment. And we tested plasma targeting and effect targeting algorithm by computer simulation using four-compartment model. So we developed the TCI capable of applying all intravenous drugs by adjusting individual pharmacokinetic parameters independently.

Effects of temperature ($13{\pm}1.5^{\circ}C$, $23{\pm}1.5^{\circ}C$) on the pharmacokinetic properties of oxolinic acid (OA) were studied after oral administration to cultured black rockfish, Sebastes schlegeli. Serum concentrations of OA were determined using HPLC-UV detector after a single dosage of 60 mg/kg body weight (average about 500 g). The peak serum concentrations of OA at $23{\pm}1.5^{\circ}C$ and $13{\pm}1.5^{\circ}C$ were $0.60{\mu}/ml$ at 30 h and $2.22{\mu}g/ml$ at 10 h post-dose, respectively. Better absorption of OA was noted at $13{\pm}1.5^{\circ}C$ compared to $23{\pm}1.5^{\circ}C$. The elimination of OA from serum was considerably faster at $23{\pm}1.5^{\circ}C$ than at $13{\pm}1.5^{\circ}C$. Both absorption and elimination of OA were affected significantly by temperature. The kinetic profile of absorption, distribution and elimination of OA in serum was analyzed by fitting to a two compartment model, with WinNonlin program. The AUC, Tmax and Cmax at $23{\pm}1.5^{\circ}C$ were $42.16{\mu}g{\cdot}h/m\ell$, 26.13 h and $0.43{\mu}g/ml$, respectively. The AUC, Tmax and Cmax at $13{\pm}1.5^{\circ}C$ were $131.98{\mu}g{\cdot}h/ml$, 8.81 h and $2.04{\mu}g/ml$, respectively.

The purpose of this study is to investigate effects of floor exercise on senior fitness test, blood lipids and arterial stiffness in elderly women with metabolic syndrome. Forty one elderly women with metabolic syndrome were randomly assigned to a exercsie group(n=23) or control goup(n=18). The exercise group performed floor exercise for 12 weeks, 3times per week. Exercise intensity was increased gradually from 30%-60% of heart rate reserve. Senior fitness, blood lipids profile and arterial stiffness were measured pre and post the 12 weeks intervention. Senior fitness(lower body strength, upper body strength, flexibility, aerobic capacity and body composition(%fat, LBM, WC)), Blood lipids(TC, TG, HDL-C and LDL-C) and Arterial stiffness(PWV) were significantly improved in the exercise group after floor exercise, however no changes were confirmed in the control group. These findings indicates that 12 weeks of floor exercise improves senior fitness, blood lipids and arterial stiffness in elderly women with metabolic syndrome. Thus, this study provides evidence that floor exercise is important methods to improve metabolic syndrome health. And it can reduce metabolic syndrome symptoms risk in elderly women with metabolic syndrome.

Annual plasma levels of vitellogenin and sex steroids were investigated in relation to the gonadal development for understanding the endocrine control of reproduction in spotted flounder, Verasper variegatus. The plasma vitellogenin level was highest, 6.36 mg/ml, in November when vitellogenesis was most active. The level, thereafter, decreased to 3.81 mg/ml in December with the initiation of spawning. On the other hand, estradiol-17 $\beta$ was highest, 2.7 ng/ml, in December, and rapidly decreased in January when spawning occurred. The decreased level of estradiol-17$\beta$, around 0.2 ng/ml, remained unchanged until May. The profiles of plasma testosterone were similar to those of estradiol-17$\beta$ in the fish, The plasma 17 $\alpha$-hydroxyprogesterone level was relatively low throughout the spawning period, but increased slightly with the initiation of ovarian development, In males, the plasma testosterone and 11-ketotestosterone were highest in December when spermiation actively proceeded, but rapidly decreased during the spawning period (January).

The effects of aerobic exercises and/or supplementation of kimchi on changes of the body composition and plasma lipids of obese middle school girls were studied. Thirty eight girls, 28 obese girls and 10 normal weighed girls, were paricipated. Among obese girls, 8 were assigned to exercise group (FG) 12 were grouped as kimchi group (KG) , and 8 were asked to practice excercise and to take kimchi simultaneously(excercise kimchi group, EKG). Ten girls whose weight is normal asked to remain o their own diet during 6 weeks of experiment (control group, CG)/ EG practiced jogging and rope-jumping for 60 minutes four times a week and KG took 3 g of freeze-dried kimchi packed in a 500 mg capsule daily which is equivalent to 30 g of fresh kimchi, EKC, EG and KG showed beneficial effects on changes of the body composition and plasma lipids compared to those of CG, EG showed greater effect than KG in reducing body fat resulted decrease in BMI, fat mas,. abdominal fat, and triglyceride concentration and increase in HDL-cholesterol. KG seemed to have greater effect on lowering plasma cholesterol and LDL-cholesterol than EG/ But the greatest effects in terms of reduction in weight, BMI fat mass, abdominal fat, total cholesterol, LDL-cholesterol, triglyceride, and increase in HDL-cholesterol were observed from EKG. These results indicate that kimchi supplemenation while practicing excercise might improve the obese state by reducing body fat content as well as reducing plasma lipids.

The purpose of this study was to investigate the effect of dietary restriction(DG), aerobic exercise(EG), dietary restriction with aerobic exercise(DEG) on weight, improvement of obesity, blood lipid profiles and metabolic risk factors of obese female college students. Experiments was conducted 5 times a week for 8 weeks. DG spent 300kcal/day, and EG used 300kcal/day to run, DEG each consumed 150kcal/day limits. As s result, in case of body composition, weight(p<.011) and BMI(p<.008) were decreased in DG group, and weight(p<.044, p<.017), body fat(p<.047, p<.018), BMI(p<.03, p<.008), body fat%(p<.036, p<.015) and WHR(p<.049, p<.027) were decreased in EG and DEG groups. In case of blood lipid profiles's change, there are some differences on TC(p<.006), TG(p<.047) according to the time. In DG:HDL-C(p<.028), in EG:TG(p<.038), in DEG:TC(p<.014), LDL-C(p<.007) have decreased. In case of metabolic risk factor's change, there are some differences on FBG(p<.001), insulin(p<.004), HOMA-IR(p<.001), leptin(p<.000), adiponectin(p<.038), resistin(p<.010) according to time. In DG:HOMA-IR(p<.035) and leptin(p<.007), EG:FBG(p<.043) and leptin(p<.003), DEG:FBG(p<.014), insulin(p<.005), HOMA-IR(p<.005), leptin(p<.016), and resistin(p<.040) have decreased. In conclusion, combined treatment of eating restriction with aerobic exercise was the most effective way to improvement of weight, blood lipid profiles and metabolic risk factors in obese female college students rather than respectively alone treatment.

The purpose of this study is to find out how underwater rehabilitation exercises affect physical fitness and blood lipids for 10 weeks and provide basic data to help prevent middle-aged women from cardiovascular diseases. The subjects of this study were middle-aged women living in Seoul, Korea. The underwater rehabilitation exercise was performed for 1 week and 3 times for 10 weeks, and the exercise time was 60 minutes for 1 time including the warm up, the main exercise and the cool down. The exercise intensity was set at 60-70% of the heart rate reserve calculated from the pre-exercise test. The measurement variables were physical fitness and blood lipid. In the data processing, descriptive statistics were presented for each measurement item and a 2-way RGRM ANOVA was conducted to examine the interaction effects between groups. The results have shown significant interaction effects in physical fitness(Flexibility, Cardiorespiratory Endurance, Muscular Endurance) and the blood lipids(TG, TC, HLD-C, LDL-C). This study found that the 10-week underwater rehabilitation exercise program of middle-aged women increased physical fitness level and decreased and increased blood lipid, which could be an effective and convergent program to prevent and reduce cardiovascular disease.

This study used raw data from the 2016-2018 National Health and Nutrition Survey to study the correlation between blood lipid and periodontal disease in Korean men and women, and selected the final 11,797 people as subjects of analysis. A stratified analysis of smoking and residential areas was conducted to see the link between blood lipid and periodontal disease in Korean men. In men, non-smokers had a significant correlation of 1.38(95% CI:1.09-1.76), and in men, the risk group had a odds ratio of 1.49(95% CI:1.16-1.91), and in smokers, the risk group had odds ratio of 1.76 (95% CI:1.39-2.23) shows that the warning group is significant in relation to the intersecting ratio 1.14(95% CI:1.16-1.70) and the risk group 1.60(95% CI:1.32-1.94) periodontal disease. In conclusion, men's blood lipids and periodontal diseases are associated with smoking or residential areas, and are especially intended to be used as basic data in developing health education programs related to systemic and periodontal diseases for men in urban areas. In developing education programs for men in urban areas in the future, we want to use them as basic data.
