One known effect of long chain n-3 polyunsaturated fatty acids is their ability to decrease plasma triglycerides. However, identification of the specific n-3 fatty acids and the underlying mechanisms responsible for this change remains uncertain. This present study was designed to evaluate the effects of moderate levels of dietary docosahexaenoic acid (22 :6(n-3)) on modulating plasma triglyderides. Male CD-1 mice were maintained for 15 days on identical diets containing either docosahexahexaenoic acid ethyl ester(1.5%, w/w) or linoleic acid(18 : 2(n-6)) ethyl ester (1.5%, w/w) . Plasma triglycerides were 40% lower in the docosahexaenoic acid group than in the linoleic acid group. Hepatic carnitine palmitoyltransferase activity (a key regulatory enzyme for mitocondria $\beta$-oxidation) was not significantly different between the dietary groups. However, plasma acid soluble acylcarnitine levels (which increase with increasing $\beta$-oxidation )were significantly higher in the decosahexaenoic acid group. This data suggests that plasma triglyceride levels are lower in mice fed diets containing moderate levels of docosahexaenoic acid compared to linoleic acid, but this effect on plasma triglycerides is not modulated through an augmentation of mitochondrial $\beta$-oxidation.

The effect of the Ginkgoic acid on the amounts of total cholesterol and triglycerides in serum from rabbit was observed. Ginkgoic acid was obtained from Ginkgo biloba L. fruits, and it was subcutaneously administered to the three days fasted rabbits. After three days starvation, the amounts of total cholesteral and triglycerides in serum of the rabbit were markedly increased. The increased amounts of total cholesteral and triglycerides were gradually decreased by administration of Ginkgoic acid, and were returned to the control levels after 4 days. According to the above results, it would be concluded that Ginkgoic acid influences for the recovery of the increased amounts of total cholesterol and triglycerides by abnormal metabolism to normal on rabbit.

Colostrum deprived, newborn pigs (N=12, $1.64{\pm}0.05kg$) were used to study the renal threshold of carnitine, and effects of emulsified medium-chain triglyceride (MCT, tri-8:0) feeding on kinetics of plasma carnitine and urinary carnitine excretion. An arterial catheter was inserted through an umbilical artery, and a bladder catheter was inserted via the urachus. Piglets were oro-gastrically gavaged with one of six carnitine levels (0, 60, 120, 180, 240, $480{\mu}mol/kg\;W^{0.75}$) with (+MCT) or without medium-chain triglycerides (-MCT) in 0.9% NaCl solution. Blood was sampled into heparinized tubes at 0, 1, 2, 4, 6, 8, 14, and 20 h after gavage, and urine was collected and pooled into 1 h or 2 h composite samples to determine free- and short-chain carnitine concentrations. Plasma from the 12 newborn piglets before gavage contained $10.6{\pm}1.2{\mu}mol/L$ free carnitine and $7.2{\pm}0.6{\mu}mol/L$ acid-soluble acyl carnitine. The renal threshold for carnitine was similar between the MCT and the +MCT group (42.6 13.1 and $46.4{\pm}2.0{\mu}mol/L$, respectively), but the correlation between plasma free carnitine and urinary excretion was altered. Plasma free carnitine linearly increased with increasing carnitine dosage (-MCT group, $R^2=0.95$, p<0.001; +MCT group, $R^2=0.91$, p<0.001), but was decreased by 50% when medium-chain triglycerides were fed. The peak in plasma free carnitine concentration was depressed by medium-chain triglycerides feeding also. Therefore, the plasma and urinary short-chain/free carnitine ratio of the +MCT group was increased by 100% and 40%, respectively (p<0.01). Feeding of medium-chain triglycerides may delay plasma carnitine elevation via altering the kinetics of absorption. Similarly, the plasma and urinary short-chain/free carnitine ratio were affected by interaction between medium-chain triglycerides and time (p<0.01). The present study suggests that an oral carnitine dose over $480{\mu}mol/kg\;W^{0.75}$ may be needed to reach the free carnitine renal threshold within a short period, especially when provided together with medium-chain triglyceride.

Thiazolidinediones (TZDs) are widely used antidiabetic drugs that activate the nuclear peroxisome proliferator-activated receptor ${\gamma}(PPAR{\gamma})$, and thereby improve the metabolic abnormalities linking hypertriglyceridemia to diabetes, hyperglycemia, insulin resistance, and cardiovascular disease. To determine whether the $PPAR{\gamma}$ ligand troglitazone regulates lipid metabolism with sexual dimorphism, we examined the effects of troglitazone on circulating lipids, body weight and the expression of hepatic genes responsible for lipid metabolism in both sexes of C57BL/6J mice. Compared to mice fed a low fat control diet, both sexes of mice fed a troglitazone-treated low fat diet for 14 weeks did not exhibit changes in body weight gain, serum total cholesterol, HDL-cholesterol and LDL-cholesterol levels. However, serum triglycerides were significantly reduced in both sexes of mice, although these effects were more pronounced among males. Furthermore, troglitazone regulated the expression of hepatic genes critical for lipid and lipoprotein metabolism, the magnitudes of which were much higher in males compared to females, as evidenced by results for increased acyl-CoA oxidase and decreased apolipoprotein C-III mRMA levels. These results suggest that $PPAR{\gamma}$ activator troglitazone may exert sexually dimorphic control of serum triglycerides in part through the differential activation of $PPAR{\gamma}$ in liver between male and female mice.

The effect of Capricornidis Cornu (C.C) on the amount of total cholesterol, triglycerides, and phospholipid in serum from rabbit were observed. The preparations were extracted by methanol, and extracted samples were oraly adminstrated to the rabbits fasted for three days. After three days starvation, the amounts of total cholesterol and triglycerides in serum of the rabbit were markedly increased, while phospholipid was slightly decreased. The amount of total cholesterol and triglycerides were gradually decreased by adminstration of the extracted samples and were returned to the control leveles after 15 days. However, the amount of phospholipid was increased to higher than the control levels by adminstraion of the drug. According to the above results, it would be concluded that the extract of C.C. and crude drug preparation containing C.C. influences for the recovery of the increased amounts of total cholesterol and triglycerides by abnormal metabolism to the normal on rabbit.

Aim To evaluate blood pressure, blood glucose and serum lipid level in obese and nonobese type 2 diabetic patients. Methods 206 obese(76 male, 130 female) and 442 nonobese(208 male, 234 female) type 2 diabetic patients underwent fasting blood glucose, 2-hour postprandial blood glucose, $HbA_1c$ total cholesterol, triglyceride, high density lipoprotein, microalbuminuria, blood urea nitrogen, creatinine and C-peptide were measured. Diabetes was diagnosed according to the American Diabetes Association(ADA)criteria. Obesity was defined as body mass index(BMI, kilograms per meters squared)${\geq}25$. Results In male, systolic blood pressure, triglycerides, microalbuminuria and C-peptide were significant higher in obese than nonobese patients. Fasting blood glucose were significantly lower in obese than nonobese patients. Diastolic blood pressure, 2-hour postprandial blood glucose, $HbA_1c$, total cholesterol, high density lipoprotein, blood urea nitrogen, and creatinine were no difference between 2 groups. In female, triglycerides and C-peptide were significant higher in obese than nonobese patients, Blood pressure, fasting blood glucose, 2-hour postprandial blood glucose, $HbA_1c$, total cholesterol, high density lipoprotein, microalbuminuria, blood urea nitrogen, and creatinine were no difference between 2 groups. Conclusion Our present study supports that increased triglycerides play a major role in increasing the risk of coronary heart disease(CHD) in obese women type 2 diabetic patients.

To examine the effects of pomegranate on cerebral blood flow and obesity, we observed regional cerebral blood flow in normal rats, as well as body weight, serum total cholesterol, serum HDL-cholesterol, serum LDL-cholesterol, serum triglycerides, serum total lipids, serum phospholipids and serum free fatty acid levels in rats fed a high fat diet. The results were as follows. Pomegranate seed extract significantly increased regional cerebral blood flow and the peel extract increased regional the cerebral blood flow in a dose dependent manner. In addition, the pomegranate extracts(seed, peel, juice) decreased body weight, serum total cholesterol, serum LDL-cholesterol, serum triglycerides, serum total lipids, serum phospholipids and serum free fatty acid levels, and increased serum HDL-cholesterol in the rats fed a high fat diet. More specially the seed extract significantly decreased serum total cholesterol, serum triglycerides and serum phospholipid levels.
