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.

Proteins secreted from bifidobacteria are believed to play important roles in human intestines via interacting with different host cells. In this respect, proteins secreted from Bifidobacterium pseudocatanulatum BP1, which has been rarely studied, were analyzed by two-dimensional gel electrophoresis (2DE). Using this approach, approx-imately 21 protein spots on a 2DE gel were detected and 10 of these spots were identified by mass spectrometry. Five spots were identified as hypothetical proteins and the remaining 5 spots were identified as a putative iron-side-rophore binding lipoprotein, a short-chain dehydrogenase/reductase SDR, an exonuclease, cytochrome P450 hydroxylase, and a putative dehydrogenase. The identification of secreted putative iron-siderophore binding lipoprotein was highly interesting since it is an important protein that is involved in ferric iron uptake in pathogenic bacteria. This finding could accelerate studies on the probiotic effect of Bifidobacterium by explaining the competition between bifidobacteria and intestinal pathogens for ferric iron.

This work was conducted to investigate dietary supplementation of oyster mushroom fruiting bodies on biochemical and histological changes in hyper and normocholesterolemic rats. Six-week old female Sprague-Dawley albino rats were divided into three groups of 10 rats each. Feeding a diet containing a 5% powder of Pleurotus ostreatus fruiting bodies to hypercholesterolemic rats reduced plasma total cholesterol, triglyceride, low-density lipoprotein (LDL), total lipid, phospholipids, and LDL/high-density lipoprotein ratio by 30.18, 52.75, 59.62, 34.15, 23.89, and 50%, respectively. Feeding oyster mushrooms also significantly reduced body weight in hypercholesterolemic rats. However, it had no adverse effects on plasma albumin, total bilirubin, direct bilirubin, creatinin, blood urea nitrogen, uric acid, glucose, total protein, calcium, sodium, potassium, chloride, inorganic phosphate, magnesium, or enzyme profiles. Feeding mushroom increased total lipid and cholesterol excretion in feces. The plasma lipoprotein fraction, separated by agarose gel electrophoresis, indicated that P. ostreatus significantly reduced plasma ${\beta}$ and pre-${\beta}$-lipoprotein but increased ${\alpha}$-lipoprotein. A histological study of hepatic cells by conventional hematoxylin-eosin and oil red O staining revealed normal findings for mushroom-fed hypercholesterolemic rats. These results suggest that a 5% P. ostreatus diet supplement provided health benefits by acting on the atherogenic lipid profile in hypercholesterolemic rats.

We analyzed and compared the concentration of total cholesterol (CHOL), high density lipoprotein (HDL) cholesterol, low density lipoprotein (LDL) cholesterol and triglyceride (TG) in serum and the serum protein electrophoresis fractions of thyroid disease patients. In comparison with the average of reference, our data showed that the average concentration of CHOL, LDL cholesterol and TG in hyperthyroidism patients were decreased significantly, but HDL cholesterol was increased significantly. In hypothyroidism patients, CHOL, HDL cholesterol, LDL cholesterol and TG were all increased significantly. In comparison of the concentration of lipids in each patient to reference range, 28.3% of hyperthyroidism patients showed abnormally low level of total cholesterol. In the patients with hypothyroidism, the percentage of patients showed abnormally high level of CHOL, HDL cholesterol, LDL cholesterol and TG were 37.7%, 10%, 68.8% and 49.1%, respectively. In our studies of serum protein electrophoresis, the average of ${\alpha}_2$-globulin and $\gamma$-globulin in hyperthyroidism patients were increased and $\beta$-globulin was decreased significantly. In hypothyroidism patients, the average of $\gamma$-globulin was increased and $\beta$-globulin was decreased significantly. In comparison of protein fractions of each patient to reference range, 38.3% and 50.0% of hyperthyroidism patients showed abnormally high levels of ${\alpha}_2$-globulin and $\gamma$-globulin, but 73.3% of patients showed abnormally low level of $\beta$-globulin. In hypothyroidism patients, 70.4% of patients were abnormally decreased in $\beta$-globulin and 63.9% of patients were abnormally increased in $\gamma$-globulin. These data suggest that the concentrations of CHOL, HDL cholesterol, LDL cholesterol and TG are not critical data for clinical interpretation of hyperthyroidism, but the levels of them are useful for interpretation of hypothyroidism patients. Our results of serum protein electrophoresis suggest that the concentration of serum protein electrophoresis fractions can be useful to understand the thyroid disease.

Very low density lipoprotein (VLDL) of commercial broiler (CB) and crossbred village chicken (AK) was purified using Fast Protein Liquid Chromatography (FPLC). The fraction collected was then confirmed as VLDL using 4% polyacrylamide gel electrophoresis and transmission electron microscopy (TEM). The particle size of VLDL is 46.8${\pm}$8.6 nm. The VLDL fraction was then subfractionated and the apolipoprotein (apo) profile was studied by sodium dodecyl sulphate polyacrylamide gel electrophoresis (SDSPAGE). The CB and AK have almost similar types of apo in both subfractions 1 and 2. The AK showed the presence of apoAI, AIV, D and E whereas the CB had apo AIV, D, E and H. The apo AIV and apo E were present in both subfractions of AK and CB.

We investigated diet supplementation with shiitake mushroom fruiting bodies on biochemical and histological changes in hypercholesterolemic rats. Six-wk old female Sprague-Dawley albino rats were divided into three groups of 10 rats each. A diet containing 5% Lentinus edodes fruiting bodies given to hypercholesterolemic rats reduced plasma total cholesterol, triglyceride, low-density lipoprotein (LDL), total lipid, phospholipids, and the LDL/high-density lipoprotein ratio by 34.33, 53.21, 75.00, 34.66, 25.73, and 71.43%, respectively. Feeding mushroom also significantly reduced body weight in hypercholesterolemic rats. However, it had no detrimental effects on plasma albumin, total bilirubin, direct bilirubin, creatinine, blood urea nitrogen, uric acid, glucose, total protein, calcium, sodium, potassium, chloride, inorganic phosphate, magnesium, or enzyme profiles. Feeding mushroom increased total lipid and cholesterol excretion in feces. The plasma lipoprotein fraction, separated by agarose gel electrophoresis, indicated that L. edodes significantly reduced plasma ${\beta}$ and pre-${\beta}$-lipoprotein but increased ${\alpha}$-lipoprotein. A histological study of hepatic cells by conventional hematoxylin-eosin and oil red-O staining showed normal findings for mushroom-fed hypercholesterolemic rats. These results suggest that shiitake mushrooms could be recommended as a natural cholesterol lowering substance in the diet.

Among the many deleterious effects of cardiopulmonary bypass[CPB], deterioration of plasma lipoprotein is a significant problem. Break-down of lipoprotein releases free fatty acids into the systemic circulation which, in turn, can cause microembolism. This study conducted on 30 patients undergoing CPB, was designed to elucidate the changes of plasma lipoproteins during and after CPB. Blood samples were taken at pre-CPB, on-CPB 30 minutes and 60 minutes, postoperative 1st, 3rd, 7th days. The levels of total cholesterol and triglyceride were measured and lipoprotein was subdivided into three kinds on electrophoresis. During CPB, the amounts of plasma total cholesterol and triglyceride decreased significantly and were recovered to pre-CPB levels after postoperative third day. There was no significant correlation between the duration and the severity of decrease in plasma total cholesterol and triglyceride levels. During CPB, the fraction of VLDL decreased and that of LDL increased. After cessation of CPB, the fraction of LDL decreased and that of HDL increased. After postoperative 1st day, the fraction of HDL decreased and that of LDL increased.

$Pyunkang-tang^{(R)}$ is a kind of herbal medicine and has been used for the treatment of atopy and allergic disease in humans over forty years. The purpose of this study was to evaluate the hematological, biochemical, and protein and lipid electrophoresis profiles after the oral administration of $Pyunkang-tang^{(R)}$ in healthy dogs. Fifteen clinically healthy beagle dogs were selected and orally administered either 33 ml of $Pyunkang-tang^{(R)}$ (group I, n = 5), 16.5 ml of $Pyunkang-tang^{(R)}$ (group II, n = 5), or 33 ml of distilled water (group III, n = 5) 3 times a day for 4 weeks. The results of the hematological, serum biochemical, and urine analysis did not differ significantly among the 3 groups. The oral administration of $Pyunkang-tang^{(R)}$ for 4 weeks was associated with significant changes in the serum globulin levels and an elevation in the high-density lipoprotein (HDL) concentrations in groups I and II (p < 0.05), compared to group III. The ${\alpha}1-globulin$ and ${\gamma}-globulin$ levels were significantly increased in group I, and the ${\alpha}1-globulin$ and ${\beta}-globulin$ levels were significantly increased in group II. The ${\alpha}2-globulin$ levels were significantly decreased in both groups. During the short-term evaluation of $Pyunkang-tang^{(R)}$ administration, we did not detect any specific adverse effects in the dogs. However, further evaluation of the safety and efficacy of $Pyunkang-tang^{(R)}$ for the treatment of atopic disease in dogs is needed.

This study was designed to evaluate the effects of tocopherol supplementation on serum $HDL_{2}$ and $HDL_{3}$ subfraction and lipoprotein pattern of young rabbits fed the different levels of dietary polyunsaturated fatty acids. White male rabbits with an average bo요 weight of 90kg were assigned into 4 groups : LP( Low PUFA) ; HP( High PUFA) ; LPT( Tocopheror added to LP), HPT(Tocopherol added to HP) by feeding safflower oil or coconut oil at loft( w/w )in addition to thew diet with or without tocopherol for 4 weeks. HDL-Chol and HDL subfractions were determined by polyanionic precipitation method, and the relative amount of lipoprotein by electrophoresis. Serum total cholesterol and TG wer slightly lowered in the group of high PUFA diet and its effect was more in the case of tocopherol supplemented. HDL-Chol level was reduced in the high PUFA diet with or without tocopherol, but overall, HDL-Chol level was not influenced by tocopherol addition and also no significant change in lipoprotein pattern when tocopherol added to the HP diet. $HDL_{2}$ level was increased in HPT group but not in LPT group when tocopherol was added to each HP and LP group, respectively. $HDL_{3}$ levels of both LP and HP groups were reduced with tocopherol supplement, but the reduction was less in the high PUFA groups so that $HDL_{2}$ : $HDL_{3}$ ratio of HP was rather close to that of LP, but it was increased when tocopherol supplemented to the HP diet. Therefore, high PUFA diet could improve the anti atherogenic factor when tocopherol supplemented.

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.
