  • The purpose of this study was to determine the association between blood lipids, fibrinogen, fasting blood sugar, lifestyle-related factors and lipoprotein(a). This study was performed with 140 healthy adults (male:80, female:60) among the teachers in primary, middle, and high school in Seoul in November 1996. Lipoprotein(a) concentration was measured with an enzyme-linked-immunosorbents assay(ELISA), and the results showed that the distribution was highly skewed and the average concentrations of male and female were $16.94{\pm}12.70\;mg/dL\;and\;17.92{\pm}7.58\;mg/dL$, respectively. The percentage of subject with lipoprotein(a) concentrations higher than 30 mg/dL was 26.4%. Univariate analysis showed significant association between lipoprotein(a) and age, alcohol, meat, and NaCl consumption (p<0.05). In multivariate analysis, lipoprotein(a) correlated positively with age (p<0.05) and meat consumption (p<0.01). These data suggest that lifestyle-related factors may affect the lipoprotein(a) concentration regarded as a risk factor of atherosclerosis disease.

  • We analyzed the concentration of serum total cholesterol (TC), high density lipoprotein cholesterol (HDLC), low density lipoprotein cholesterol (LDLC), triglyceride (TG) and the serum lipoprotein electrophoresis fractions in hypertensive patients (hypertension group, n=182). The average concentration of lipids and lipoprotein fractions in the hypertension group was compared to that of the normal group. The average concentrations of serum TC, LDLC and TG in the hypertension group were significantly higher than those of the normal group (3.3%, 11% and 70%, respectively) (P<0.05). But HDLC was nonsignificantly lower (2%) (P<0.05). In the hypertension group, the percentages of patients who had an abnormally high level of total cholesterol, HDLC, LDLC and TG were 12.1%, 8.2%, 24.2% and 44.5%, respectively. The average of ${\beta}$-lipoprotein (27.5%) and pre ${\beta}$-lipoprotein (12.6%) were significantly higher, whereas ${\alpha}$-lipoprotein (15.2%) was significantly lower in the hypertension group than in the normal group (P<0.05). The percentages of patients who had an abnormally high level of very low density lipoprotein (pre ${\beta}$-LP), LDLC (${\beta}$-LP) and chylomicron were 31.3%, 17.0% and 12.6%, respectively. This study suggests that an increasing of total cholesterol, LDLC and TG, pre ${\beta}$-LP, ${\beta}$-LP and chylomicron are associated with a risk factor for hypertension.

  • Rat lipoprotein-deficient plasma possessed a lipid tramsfer inhibitory activity when it was added to purified human plasma lipid transfer protien, while it lacked a lipid transfer activity. Incubation of whole rat plasma with partially purified human lipid transfer protein resulted in big changes in lipid distribution of rat plasma lipoproteins. There w was a 4-fold increase in cholesteryl ester(CE) and 4 47 % reduction in triglyceride(TG) in very low density lipoproteins after 2싹lour incubation. In high density lipoprotein $2(HDL_2)$ there was a 9­fold increase in TG and 33 % reduction in CEo HDL3 had 82 % reduction in CE. The result indi­c cates that the absence of the lipid transfer activity in rat plasma can be ascribed not to the inability of rat lipoproteins to serve as substrates but to the lack of 야Ie lipid transfer protein in rat plasma. Th­e erefore, species differences in lipid transfer betwe­e en lipoproteins should be taken into consideration to interpret results of studies on lipoprotein m.eta­b bolism using rats.

  • To evaluate an effect of dietary protein on lipoprotein profile serum of carbon tetrachloride-treated rats, carbon tetrachloride (50% in olive oil) was twice given at 0.1ml/100g body weight at intervals of 24hours to the male rats and then the degree of liver damage in carbon tetrachloride-treated animals fed a low protein diet was compared with that fed a high protein diet. The increasing rate of liver weight/body weight and the serum levels of alanine aminotransferase in carbon tetrachloride-treated rats to the control group were higher in rats fed high protein diet than those fed low protein diet. In the serum levels of lipid (total lipid, total cholesterol and triglyceride) remarkable differences were not found between low protein diet group and high protein diet group. But these serum lipids in carbon tetrachloride-treated rats were decreased and the decreasing rate of serum lipids to control group were higher in carbon tetrachloride-treated rats fed high protein diet than those fed low protein diet. Under the animal model as identified by the present data herein, serum pre $\beta$-lipoprotein and $\alpha$-lipoprotein fractions were decreased in carbon tetrachloride-treated rats, but the serum levels of $\beta$-lipoprotein were rather increased in the both group by the injection of carbon tetrachloride. Especially, the decreasing rate of $\alpha$-lipoprotein fraction was higher in $CCl_4$-treated rats fed a high protein diet than those fed a low protein diet to its control group and the increasing rate of serum $\beta$-lipoprotein fraction was also higher in $CCl_4$-treated rats fed high protein diet than those fed low protein diet.

  • In order to investigate the effect of ginseng saponins on the activity of lipoprotein lipase, it was attempted to conform the enzymatic hydrolysis of chylomicron with post-heparin induced plasma lipoprotein lipase of normal rabbit in vitro. And the activity of lipoprotein llipase was determined by the quantitative determination of liberated free fatty acids on the hydrolysis of chylomicron. As the result, it was observed that the ginseng saponins accelerated the hydrolysis of chylomicron by post-heparin plasma in vitro. And the optimum concentration of ginseng saponins for the activity of the lipoprotein lipase in the 2% bovine serum albumin was $10^{-4}%$. But ginseng saponins on the hydrolysis of chylomicron was influenced by the presence and the absence of albumin. And the optimum concentration of albumin and Na-cholate on the activity of lipoprotein lipase was each of the $10^{-6}%$ albumin and 5mM Na-cholate. From these results, it seems that ginseng saponins might stimulate the intravascular hydrolysis of chylomicron.

  • Cirsium japonicum water extracts has been used to treat vascular related diseases. We have previously reported that Cirsium japonicum extracts activated estrogen receptors. It is widely known that estrogen increases the high density lipoprotein cholesterol and decrease the low density lipoprotein cholesterol on the lipid profile. But effects of Cirsium japonicum on lipid profile are not reported yet. Therefore, we have studied the effects of Cirsium japonicum on the lipid content in ovariectomized rats. Thirty Sprague-Dawley (SD) rats of $210{\pm}20\;g$ were studied for 10 weeks. The rats were divided into five groups; (I) sham, no ovariectomized rats plus olive oil, (II) ovariectomized rats plus olive oil, (III) ovariectomized rats plus 0.5 mg/kg $17{\beta}$-estradiol (E2) in olive oil, (IV) ovariectomized rats plus 0.5 mg/kg Cirsium japonicum in olive oil, and (V) ovariectomized rats plus 5 mg/kg Cirsium japonicum in olive oil. Treatment with Cirsium japonicum or E2 induced significant reduction in total cholesterol, low density lipoprotein cholesterol/total cholesterol, total cholesterol/high density lipoprotein cholesterol and low density lipoprotein cholesterol/high density lipoprotein cholesterol compared to control group as well as increase in uterine weight. However, changes in triglycerides levels were different. Our results suggest that Cirsium japonicum is functionally similar to E2 in vivo as well as in vitro.

  • Fifteen cases of primiparas and their offsprings (fetal cord) were investigated with regard their serum total, free and esterified cholesterol by means of Liberman Buchard reaction. The serum ${\alpha}-and\;{\beta}-lipoprotein$ were analyzed by cellulose acetate electrophoresis, and the serum atherolipid numbers were calculated on the bases of the serum total cholesterol and ${\beta}-/{\alpha}-$ lipoprotein ratio, with the following conclusion. 1.Total, free and esterified cholesterol are $178.9{\pm}25.3$, $45.1{\pm}12.6$ and $133.7{\pm}20.6\;mg.%$ in the normal control women, $201.5{\pm}29.5,\;58.7{\pm}42.1$ and $157.1{\pm}26.2\;mg.%$ in the maternal blood, showing hypercholesterolemia in the latter as compared to the former. 2. The serum total, free and esterified cholesterol in the cord blood are $94.5{\pm}20.4$, $32.9{\pm}1.5$ and $61.2{\pm}18.9mg.%$, showing hypocholesterolemia as compared to the control women and maternal blood. 3. The serum ${\alpha}-$, $pre-{\beta}$, ${\beta}-lipoprotein$ and chylomicron are $24.2{\pm}4.2$, $17.3{\pm}3.4$, $51.8{\pm}4.8$ and $6.0{\pm}1.6%$ in the normal women, whereas $14.9{\pm}2.1$, $22.2{\pm}5.1$, $58.7{\pm}3.3 and 3.1{\pm}1.2%$ in the maternal serum, $32.4{\pm}8.1$, $28.8{\pm}2.4$, $25.8{\pm}7.0$ and $3.1{\pm}0.9%$ in the cord serum, showing $hyper-{\beta}-lipoproteinemia$ in the former and $hypo-{\beta}-lipoproteinemia$ in the latter. 4. The serum atherolipid number of the normal control women, maternal cord blood are $4.21{\pm}1.24$, $8.02{\pm}1.42$ and $1.12{\pm}0.37$, showing hyperlipemia in the former and hypolipemia in latter. 5. The relative ratio of the serum free and esterified cholestrol of both normal control women and maternal blood is about 1 : 3, while that of the fetal blood about 1 : 2. 6. The relative ratioes of the serum ${\alpha}-and$ ${\beta}-lipoprotein$ in the control women is about 1 : 2, that of materna blood about 1 : 3 and that of the fetal blood about equal magnitude. 7. The serum esterified cholesterol, ${\alpha}-lipoprotein,\;{\beta}-/{\alpha}-lipoprotein$ ratio and atherolipid number fluctuates are proportionally between the maternal and fetal blood, while the serum free, total cholesterol and ${\beta}-lipoprotein$ between the two vary inversely with statistically significant corelations. 8. It is apparent from the above results that the fetal nutritional demand for lipids resulted from hypocholesterolemia and hypo ${\beta}-lipoproteinemia$ seems to be met satisfactorily by maternal hypercholesterolemia and hyper ${\beta}-lipoproteinemia$, which seems to pose a significant maternal-infant nutritional relationship. A brief ciscussion was made on these conciusion in the light of biochemistry and endocrinology.
