A simple and rapid method, based on separation of a flying oil into monomeric, dimeric and oligomeric triglyceride by means of high performance size exclusion chromatography on Ultrastyragel column (500 A), is proposed for evaluation of the quality of used frying oil. The relative area of the monomeric triglyceride was decreased with frying time increase, however, the decrease rate was significantly reduced by treatment of a composited powder (porous rhyorite/citric acid 40/56/4). This measurement showed good linear relationship with change in polar component measurement. There were no significant differences between the slopes of regression lines in both treated and non-treated frying oil system for relationship between monomeric triglyceride and polar component. By this method, it was found that a frying oil habe to be discarded if the content monomeric triglyceride decreased to 71%, which was corresponed to 27% polar component.

In this study, sesame oil was chosen as the experimental sample and analysed for its triglyceride composition by high-performance liquid chromatography(HPLC) in combination with gas liquid chromatography(GLC). The triglycerides were separated from sesame oil by liquid chromatographies on Bio-Beads SX-2 and on Sephadex LH-20, and fractionated into five groups on the basis of their partition numbers by reverse phase HPLC on a column packed with $\mu-Bondapak$ C18 using methanol-chloroform mix-ture as a solvent. Each of these collected fractions gave one to three peaks in the GLC chromatograms according to the acyl carbon number of the triglyceride, and fatty acid composition of the triglyceride was also analysed by GLC. From the results, it was found that the sesame oil consists with twenty one kinds of triglyceri-des, and the major triglycerides of sesame oil are those of $(2\;{\times}\;C18:1,\;C18:2\;;\;17.1\%),\;(C18:1,\;2{\times}C18:2\;;\;17.0\%),$ $(3\;{\times}\;C18:2\;;\;17.0\%),\;(3\;{\times}\;C18:1\;;\;10.9\%),$ $(3\;{\times}\;C18:2\;;\;9.6\%),\;(C16:0,\;C18:1,C18:2\;;\;7.9\%),$ $(C16:0,\;2\;{\times}\;C18:1\;;\;7.4\%),\;(C16:0,\;2\;{\times}\;C18:2\;;\;6.8\%),$ $(C18:0,\;C18:1,\;C18:2\;;\;3.1\%),\;(2\;{\times}\;C18:0,\;C18:2\;;\;1.5\%)$ $(C18:0,\;2\;{\times}\;C18:1\;;\;1.4\%),\;(C16:0,\;C18:0,\;C18:1\;;\;1.3\%),$ $(2\;{\times}\;C16:0,\;C18:1\;;\;1.2\%),\;and\;(C16:0,C18:0,\;C18:2\;;\;1.0\%)$.

This study investigated the effect of lemon balm (Melissa officinalis) extract on improving blood triglycerides according to the extraction solvent using 3T3-L1 cells. Lemon balm was extracted with water (MOW100), 70% ethanol (MOE70), 50% ethanol (MOE50), and 30% ethanol (MOE30). To verify its efficacy on improving blood triglycerides, cell viability, lipid accumulation, triglyceride (TG) content, and expressions of protein kinase A (PKA), adipose triglyceride lipase (ATGL), hormone-sensitive lipase (HSL), perilipin, and CGI-58 proteins were evaluated. Cytotoxicity was not evident up to an extract concentration of 1 mg/mL. Lipid accumulation and TG content were decreased in a concentration-dependent manner compared to their levels in the control group. When the MOW100 extract was applied at a concentration of 0.2 mg/mL, an inhibitory effect was evident, with lipid accumulation inhibited by 21.3% and TG content reduced by 32.7%. PKA phosphorylation and ATGL HSL and CGI-58 levels were increased. The data indicate that lemon balm extract obtained using water is more efficacious than extracted with ethanol. The aqueous extract shows potential in triglyceride control through lipolysis and lowering triglyceride levels.

This study investigates the utility of the Triglyceride-glucose(TyG) index and Cardiometabolic Index(CMI) as predictors for diagnosing metabolic syndrome. The study involved 1970 males, 1459 females, totaling 3429 participants who underwent health checkups at P Hospital in Busan between January 2023 and June 2023. Metabolic syndrome diagnosis was based on the presence of 3 or more risk factors out of the 5 criteria outlined by the American Heart Association/National Heart, Lung, and Blood Institute(AHA/NHLBI), and participants with 2 or fewer risk factors were categorized as normal. Statistical analyses included independent sample t-tests, chi-square tests, Pearson's correlation analysis, Receiver Operating Characteristic(ROC) curve analysis, and logistic regression analysis, using the Statistical Package for the Social Sciences(SPSS) program. Significance was established at p<0.05. The comparison revealed that the metabolic syndrome group exhibited attributes such as advanced age, male gender, elevated systolic and diastolic blood pressures, high blood sugar, elevated triglycerides, reduced LDL-C, elevated HDL-C, higher Cardiometabolic Index, Triglyceride-glucose index, and components linked to abdominal obesity. Pearson correlation analysis showed strong positive correlations between waist circumference/height ratio, waist circumference, Cardiometabolic Index, and triglycerides. Weak positive correlations were observed between LDL-C, body mass index, and Cardiometabolic index, while a strong negative correlation was found between Cardiometabolic Index and HDL-C. ROC analysis indicated that the Cardiometabolic Index(CMI), Triglyceride-glucose(TyG) index, and waist circumference demonstrated the highest Area Under the Curve(AUC) values, indicating their efficacy in diagnosing metabolic syndrome. Optimal cut-off values were determined as >1.34, >8.86, and >84.5 for the Cardiometabolic Index, Triglyceride-glucose index, and waist circumference, respectively. Logistic regression analysis revealed significant differences for age(p=0.037), waist circumference(p<0.001), systolic blood pressure(p<0.001), triglycerides(p<0.001), LDL-C(p=0.028), fasting blood sugar(p<0.001), Cardiometabolic Index(p<0.001), and Triglyceride-glucose index (p<0.001). The odds ratios for these variables were 1.015, 1.179, 1.090, 3.03, and 69.16, respectively. In conclusion, the Cardiometabolic Index and Triglyceride-glucose index are robust predictive indicators closely associated with metabolic syndrome diagnosis, and waist circumference is identified as an excellent predictor. Integrating these variables into clinical practice holds the potential for enhancing early diagnosis and prevention of metabolic syndrome.

Hypertriglyceridemia is one of the metabolic syndrome that is often observed as a result of lipid abnormalities. It is associated with other lipids, metabolic disorders, cardiovascular disease and liver disease. Korean red ginseng is known to affect obesity, dyslipidemia, liver disease and liver function, but the mechanism of its effect is not clear. This study examined the beneficial effects of hypertriglyceridemia and the mechanism of action of Jinan red ginseng extract (JRG) in hepatoma cells. To measure the levels of triglyceride accumulation, we studied the expression of proteins and mRNAs related to lipidogenesis in hepatoma cells (Huh7 and HepG2). JRG decreases the lipidogenic markers, peroxisome proliferator-activated receptor γ (PPARγ), CCAAT-enhancer-binding proteins α (C/EBPα) and C/EBPβ which are major regulators of triglyceride synthesis in hepatoma cells. We also found that JRG reduced sterol regulatory element binding proteins 1c (SREBP-1c), C/EBPα and C/EBPβ by regulating liver X receptor (LXR) and stearoyl CoA desaturase (SCD) expressions. In addition, the first-limited step of synthesis triglyceride (TG), glycerol-3-phosphate (G3P) is decreased by JRG. These results suggest that the anti-hypertriglyceride effect of JRG in hepatoma cells could be accompanied with the inhibition of lipidogenic transcription factors by regulating LXR and SCD expression.

The study was conducted to investigated the effect of dietary levels of zinc (Zn) on lipid metabolism in cadmium (Cd) treated rats. Sixty male Sprague-Dawley rats weighing about 110$\pm$10g were divided into 6 groups. The Zn levels were low (0ppm), control (30 ppm) and Cd-treated groups were administrated with Cd chloride (5.0mg/kg of body weight) by oral intubation at the same time once a week. Serum total lipid, triglyceride , total cholesterol and DHL-cholesterol contents decreased significantly in low Zn group. In serum dietary high Zn group, it decreased significantly in the content of triglyceride but total cholesterol and HDL- cholesterol revealed increase slightly . Total lipid and triglyceride contents increased by Cd oral intubation, but triblyceride content of control group decreased significantly in Cd-treated groups. HDL-cholesterol content also decreased by Cd oral intubationl. Cd-treatment increased total cholesterol content in low Zn group. Liver triglyceride content increased as dietary Zn level became more increasing and total lipid was not influenced by dietary Zn levels. Liver cholesterol content was higher in low and high Zn groups than that of control group. Liver phospholipid content decreased in low Zn group . Oral intubation of Cd increased in the contents of triglyceride and total lipid. The content of liver Zn was not influenced by the dietary low Zn but that of serum showed a remarkable increased . Oral Cd intubation increased the Cd contents of liver and serum.

This study was conducted to investigate the effects of chitosan, chitosan oligomer and beef tallow of different levels on lipid metabolism in rats, Seventy male rats of the Sprague-Dawley strain were blocked into 10 groups according to body weight , and were raised for 4 weeks. Dietary fat levels were 20% en and 40% en, and chitosan and chitosan oligomer were given at levels of 05, 3%, and 5%(wt/wt) of diet. The results are summarized as follows, chitosan oligomer supplement decreased serum total lipid, as chitosan 양, and exhibited a tendency to decrease serum total cholesterol. Chitosan oligomer supplement tended to increase the HDL cholesterol ; total cholesterol ration as chitosan did. Liver total lipid and triglyceride concentration were lower in high fat groups than in low fat groups. Liver total lipid concentrations was decreased slightly by chitosan and sigfnificantly by chitosna ligomer. Epididymal fat pad total lipid. total cholesterol and triglyceride concentration were slightly decreased by chitosan and chitosan oligomer supplement, especially in high fat groups. fat absorptivity was decreased by low fat level, chitisan and chitosan oligamer supplement. Fecal excretion of total lipid and triglyceride were increased by high fat level, chitosan and chi샌무 oligomer supplement. However, fecal excretion of total cholesterol was increased by high fat level and chitosan supplement. This indicated that chitosan and chitosan oligomer were effective in interfering with lipid and triglyceride absorption, In conclusion, chitosan oligomer at levels of 3% and 5% has more effective lipid, cholesterol and triglyceride lowering activity than chitosan.

Gestational diabetes mellitus(GDM) is likely to develop type 2 diabetes mellitus, cardiovascular disease, metabolic syndrome after delivery. Infants of diabetic women have higher incidence of congenital malformations than those of non-diabetic women. This study was performed to determine elevation factors associated with increased blood glucose in 350 pregnant women. Subjects were examined in June, 2011 to September, 2011 in Geongnam province. Fasting blood glucose, total cholesterol, triglyceride levels were measured by Olympus AU 680, and their body mass index (BMI) calculated. The mean total cholesterol levels were 223.22 mg/dL, triglyceride 188.38 mg/dL, and fasting blood glucose 100.18 mg/dL. Serum glucose level was significantly higher in the age group of 40 years($109.51{\pm}16.26mg/dL$) than 20 years and 30 years. And increase in triglyceride(>250 mg/dL) was significantly related to high blood glucose level($110.83{\pm}24.78mg/dL$), and increase in BMI(>26) was significantly related to high blood glucose level($114.03{\pm}27.09mg/dL$). However, cholesterol levels were not significantly related to high blood glucose level. In conclusion, the significant elevation factors in relation to the glucose levels were age, triglyceride, and BMI.
