This paper describes the effects of thermally oxidized tallow on the serum lipids profile and radical scavenging activity (RSA) of the lipids extracted from the different tissues of the rabbits. Tallow was thermally oxidized at $130^{\circ}C$ for 9, 18, 27, 36 and 45 h respectively. Thermally oxidized tallow was fed to the local strain of Himalayan rabbits for one week. Results show that oxidation increases the formation of hydroperoxides and decrease the level of radical scavenging activity of the tallow. The rabbit serum lipids profile showed a dose dependent increase in triglyceride, total cholesterol and LDL-cholesterol. However, no statistically significant increase was observed in the HDL-cholesterol with an increase of oxidation time. Serum glucose and rabbits body weight decrease significantly (p < 0.05) and was highly correlated with the serum lipids profile. The percent RSA of the lipids extracted from the liver, brain and muscles tissues showed a significant decrease with respect to 0.5, 1.0 and 1.5 g/body weight as well as oxidation time. Data suggests that thermal oxidation and use of thermally oxidized beef tallow is harmful and therefore an alternative way of cooking should be used.

The lipid composition of total serum lipids were investigated by latroscan TH-10 TLC analyzer in 69 healthy subjects and 62 patients with hypercholesterolemia. Total serum lipids level in healthy subjects was higher in females than males. There was a increase in total serum lipids level with increasing total serum cholesterol level in patients with hypercholesterolemia, regardless sex. Total serum lipids obtained from healthy subjects and patients with hypercholesterolemia were separated into phospholipids, free cholesterol, free fatty acids, triglycerides and cholesterol esters. Increasing the level of total serum cholesterol in the patients resulted in a decrease in the level of phospholipids, which was a major lipid fraction, indicating that HDL level in the patients was also decreased. However, cholesterol esters, triglycerides and free cholesterol levels in the patients were higher than those found in healthy subjects. The FC/CE ratio for male patients was lower than for healthy males, while in female patients, this ratio was similar to that observed in healthy females.

Purpose: This study examined the effects of foot-reflexology massage on body weight, lower extremity edema, and serum lipids in postpartum women. Method: This study was a nonequivalent control-group pretest-posttest design. Postpartum women were assigned to the experimental group (n=16) or a control group (n=15). Foot reflexology massage was applied 5 times a week, for a total of 2 weeks to the experimental group. The tool for measuring lower extremity edema was the girth of the thigh, and the calf. The measuring tool for serum lipids was total cholesterol and TG in blood serum by clinical process. Data was analyzed by $x^2$-test, t-test, and paired t-test, ANOVA using SPSS/Win PC 14.0. Results: There was a statistically significant decrease in levels of TG in blood serum in the experimental group compared to the control group. Conclusion: Foot reflexology massage is a useful nursing intervention that decreases serum lipids level in postpartum women. Therefore foot reflexology massage is recommended as a nursing intervention strategy for serum lipids reduction in postpartum women.

This study examined the effect of dietary lipids and guar gum on lipid metabolism in ovariectomized rats. The experimental animals received ovarietomy (OVX). Lipids sources were divided into 3 groups (soybean oil(SB), beef tallow(BT)) and fish oil(FO)) and guar gum was supplemented to each lipid diet (SBG, BTG, FOG). Experimental diets were fed to therats for 16 weeks. Serum triglyceride (TG) levels were higher in the BT group and lower in the FO group as compared to the SB group .Serum total cholesterol (Tc) and HDL-C levels were lower in the FO group as compared to the SB group. Serum LDL-C and phospholipid levels were lower in the FO group as compared to the SB group. Serum lipids levels were lowered by guar gum supplement. Serum SFA(saturated fatty acids) contents were not significantly influenced by dietary lipids and guar gum. Serum MUFA(monounsaturated fatty acids) contents were the lowest in the SB group. Fecal weight was highest in the beef tallow group and lowest in the fish oil group. Fecal weight was increased by guar gum supplement in all lipid groups. Total bile acid content in feces was increased by guar gum supplement in the soybean oil and beef tallow groups. The endothelial cells of the beef tallow group changed from a flat shape to distorted round and enlarged shapes. The subendothelial layer was the thickness the thickest in the beef tallow group ; the interspace between elastic lamina was widened and elastic lamina was straightened and partly disrupted . The fish oil group showed more porminient endothelial cells and subendothelial layer. Internal elastic membrane and elastic lamina exhibited regularly wavy shapes. Guar gum supplement showed positive effects in all lipids groups. Based on the above results , it is suggested that beef tallow increased serum TG levels and injured the wall of the aorta. On the other hand, fish oil , which decreased serum lipid levels, has a positive effect on the walls of the aorta. Guar gum protects the aorta from injury by reducing the serum lipid levels. Therefore, it is suggested that soybean oil and beef tallow consumed with guar gum is beneficial.

In the presence of a photosensitizer, rose bengal, phooxidatlon in serum total lipids has been studied and the effects of ginseng water extract and saponins on it have reviewed. In the presence of rose bengal, serum total lipids undergo photooxidation and produce lipid hydroperoxides. On the other hand, ginseng water extract and dial saponins largely inhibit photooxidation and decrease the amount of lipid hydroperoxides in serum total lipids.

The purpose of this study was to evaluate the usefulness of variables which were known to be related to blood pressure for discriminating between hypertensive and normotensive groups. Variables were obesity, serum lipids, life style-related variables such as smoking, alcohol, exercise, and stress, and demographic variables such as age, economical status, and education. The data were collected from 400 male clients who visited one university hospital located in Incheon, Republic of Korea, from May 1996 to December 1996 for a regular physical examination. Variables which showed significance for discriminating systolic blood pressure in this study were age, serum lipids, education, HDL, exercise, total cholesterol, body fat percent, alcohol, stress, and smoking(in order of significance). By using the combination of these variables, the possibility of proper prediction for a high-systolic pressure group was 2%, predicting a normal-systolic pressure group was 70.3%, and total Hit Ratio was 70%. Variables which showed significance for discriminating diastolic blood pressure were exercise, triglyceride, alcohol, smoking, economical status, age, and BMI (in order of significance). By using the combination of these variables, the possibility of proper prediction for a high-diastolic pressure group was 71.2%, predicting a normal-diastolic pressure group was 71.3%, and total Hit Ratio was 71.3%. Multiple regression analysis was performed to examine the association of systolic blood pressure with life style-related variables after adjustment for obesity, serum lipids, and demographic variables. First, the effect of demographic variable alone on the systolic blood pressure was statistically significant (p=.000) and adjusted $R^2$was 0.09. Adding the variable obesity on demographic variables resulted in raising adjusted $R^2$to 0.11 (p=.000) : therefore, the contribution rate of obesity on the systolic blood pressure was 2.0%. On the next step, adding the variable serum lipids on the obesity and demographic variables resulted in raising adjusted R2 to 0.12(P=.000) : therefore, the contribution rate of serum lipid on the systolic pressure was 1.0%. Finally, adding life style-related variables on all other variables resulted in raising the adjusted $R^2$to 0.18(p=.000) ; therefore, the contribution rate of life style-related variables on the systolic blood pressure after adjustment for obesity, serum lipids, and demographic variables was 6.0%. Multiple regression analysis was also performed to examine the association of diastolic blood pressure with life style-related variables after adjustment for obesity, serum lipids, and demographic variables. First, the effect of demographic variable alone on the diastolic blood pressure was statistically significant (p=.01) and adjusted $R^2$was 0.03. Adding the variable obesity on demographic variables resulted in raising adjusted $R^2$to 0.06 (p=.000) ; therefore, the contribution rate of obesity on the diastolic blood pressure was 3.0%. On the next step, adding the variable serum lipids on the obesity and demographic variables resulted in raising the adjusted $R^2$ to 0.09(p=.000) ; therefore, the contribution rate of serum lipid on the diastolic pressure was 3.0%. Finally, adding life style-related variables on all other variables resulted in raising the adjusted $R^2$ to 0.12 (p=.000) : therefore, the contribution rate of life style-related variables on the systolic blood pressure after adjustment for obesity, serum lipids, and demographic variables was 3.0%.

The purpose of this research is to investigate how obesity and eating behavior are related to the concentration of serum insulin and lipids and blood pressure of middle-aged men The sample for this study utilizes 240 middle-aged men between th4 age of 40 and 60 living in the city of Kumi. Through a process of anthropometry and categorization by relative body weight, the sample is devide into two groups, the obese group (51 men) and the normal group (129 men). The results of the study were as follows : 1111111. The men from the obese group with the exception of height, subs-capular/triceps skinfold girth ratio(STR) had a higher level of body mass index (BMI), waist and hip circumference, waist/hip girth ratio(WHR), subscapular and triceps skinfold thickness than the normal group (P=0.0001). 2. In comparing the serum insulin and lipids between the obese and normal group, the obese group had a higher level of insulin and triglyceride (P=0.016, P=0.050) but a lower concentration of HDL-cholesterol and HDL-cholesterol/total cholesterol (P=0.034, P=0.004). Also, the obese group had a higher level of systolic and diastolic blood pressure (P=0.001, P=0.029). When looking at the relationship between the serum insulin and lipids and anthropometric measurements, the relationship between waist/hip girth ratio(THR), the concentration of fasting serum insulin and lipids were stronger than the obesity index, body mass index(BMI). 3. Men who exercised regularly had a lower total cholesterol and systolic blood pressure 9P=0.049, P=0.041), and a higher level of HDL-cholesterol/total cholesterol (P=0.004). There was no observable relationship between the food habit score, the preference for fiber foods, and the concentration of serum lipids. Also, the concentration of serum lipids had no apparent effect on the preference for salty, sweet, and greasy foods.
