Objectives The objective of the study was to investigate effects of ChondroT by improvement of blood metabolites in high-fat diet (HFD)-induced hyperlipidemia rat model. Methods Sprague-Dawley rats were randomly assigned to intact, control, simvastatin, and CT100, CT200 and CT400 (each n=6). For observing cholesterol change, animals were first fed high fat diet for 5 weeks and then high fat diet and drugs for 3 weeks. At the end of the experiment, total cholesterol, triglyceride, high density lipoprotein-cholesterol (HDL-C) and low density lipoprotein-cholesterol (LDL-C) were analyzed by obtained blood collection. Further, amplified leptin, peroxisome proliferator activated receptor (PPAR) and adiponectin DNA were observed by reverse transcription polymerase chain reaction analysis. Results Observing the effect of ChondroT on the change of lipid metabolism in hyperlipidemia-induced rats, triglyceride and total cholesterol were significantly decreased in SV100 group, HDL-C was significantly increased in SV100, CT100 and CT200 groups, and LDL-C was significantly decreased in SV100, CT100, CT200 and CT400 groups, compared to the control group. Leptin level in hyperlipidemia-induced rats was significantly decreased in CT100 and CT200 groups, compared to the control group. The effect of ChondroT on adiponectin level in hyperlipidemia-induced rats was significantly increased in SV100, CT100 and CT200 groups. PPAR level in hyperlipidemia-induced rats was significantly decreased in SV100, CT200 and CT400 groups. Platelete activating factor level in hyperlipidemia-induced rats was significantly decreased in CT100 and CT200 groups. Conclusions Based on these results, it could be suggested that ChondroT has certain effects of improving blood metabolites in HFD-induced hyperlipidemia.

The effect of treatment with pine needle oil complex (complex of pine needle oil and Korean medicinal herbs) upon rat hepatocytes exposed to alcohol was investigated. We compared body weight gain and ratios of liver and kidney to body weight and the serum biochemistry of rats administered both alcohol and Pine needle oil complex to control rats treated with alcohol alone. Pine needle oil complex treatment resulted in a significant reduction in the levels of aspartate aminotransferase (AST), alanine aminotransferase (ALT) and triglycerides (TG) compared to the control rats. These data suggest that Pine needle oil complex represents an excellent candidate for protection of rat hepatocytes from alcohol-mediated damage.

High performance liquid chromatography (HPLC) analysis on the MeOH extract of Ligularia stenocephala leaves identified six caffeoylquinic acids, viz. 3,4-di-O-caffeoylquinic acid, 3,5-di-O-caffeoyl-mucoquinic acid, 3,5-di-O-caffeoylquinic acid, 4,5-di-O-caffeoylquinic acid, 5-O-caffeoylquinic acid, and 3-Ocaffeoylquinic acid using standard compounds, and determined the quantity of each extract. Percentage of total caffeoylquinic acids of the MeOH extract and its BuOH fraction were calculated as $67.83{\pm}3.79%$ and $94.52{\pm}1.84%$, respectively. Since the caffeoylquinic acid-rich MeOH extract exhibited a potent peroxynitrite-scavenging effect in vitro ($IC_{50}=0.87{\pm}0.33\;{\mu}g/ml$ (mean $\pm$ SEM)), the experiment was designed to identify whether or not that extract has an anti-obesity effect on rat obesity induced by high fat diet. Oral administration of the MeOH extract and its BuOH fraction abundant in caffeoylquinic acid decreased the rat body weight to the level of untreated group and decreased abdominal fat pad weight. The atherogenic index and thiobarbituric acid-reactive substance (TBARS) values were restored by treatment, indicating that the caffeoylquinic acid-rich extract probably inhibited hyperlipidemia and oxidative stress caused by high fat diet. These results suggest that L. stenocephala in vegetable form or its caffeoylquinic acid-rich fraction (BuOH fraction) as an agent can be used for treatment or prevention of obesity.

To develop Allium victorialis var. platyphyllum (Liliaceae) for an available functional food, pharmacological experiments on the extracts of this plant were undertaken in the rat treated with streptozotocin, poloxamer-407 and $CCl_4$. The two MeOH extracts were obtained from the leaves and the bulbs, respectively. The three agents, streptozotocin, poloxamer-407 and $CCl_4$, were treated to induce diabetes mellitus, hyperlipidemia and hepatic injury, respectively. Treatment with the leaf extract lowered blood glucose by 24.9% at 200 mg/kg (p.o.) in the STZ-treated rat and prohibited the increase of body weight, water consumption and food intake. This exσact also significantly decreased not only thε plasma cholesterol and triglyceride in the poloxamer-407-treated rat by 35.3% but also serum ALT by 49.0%. The potency was found by overall estimation on the experimental results as followings: 200 mg/kg leaf extract> 200 mg/kg bulb extract> 100 mg/kg leaf exσact> 100 mg/kg bulb extract. These results suggested that this plant might have the availability for a functional food. It was also suggested that the leaves are more effective than the bulbs for the functional vegetable, especially in hyperlipidemia and hepatic injury.

Pine needle oil and Korean medicinal herbs (KMH) are known as effective therapeutic agents on various blood vessel disease. We have already reported the ameliorative effect of complex of pine needle oil and Korean medicinal herbs against hyperlipidemia. But safety and non - toxicity of pine needle oil and Korean medicinal herbs to normal animal cells have not been studied clearly. In this study, we investigated whether pine needle oil and Korean medicinal herbs show side effects on rat or not. These materials were administered to rats, and subacute toxicity was examined by measuring the hematological values, CBC differentiation, biochemical levels of blood (TP, total protein; albumin; ALP, alkaline phosphotase; AST, aspatate aminotrans- ferase; ALT, alanine aminotransferase; T-Chol., total cholesterol; T-Bil., total bilirubin) and urine analysis, suggesting that the sample have no side effects and cytotoxicity. These results indicate that the complex of pine needle oil and Korean medicinal herbs may effective non- toxic, safety therapeutic agents on hepatocytes and hyperlipidemia.

In this study, we investigated a dose-dependent hypolipidemic and antioxidant effects of tocotrienol-rich fraction (TRF) from grape seeds. After induction of hyperlipidemia for 4 weeks, rats were supplemented with different dose (5, 25, and 50 mg/kg BW/day) of TRF for 1 week. Oral administration of TRF (50 mg/kg BW/day) decreased the plasma triglyceride (TG, 162.6 mg/dL), total cholesterol (TC, 83.7 mg/dL), low density lipoprotein-cholesterol (LDL-C, 20.3 mg/dL), malondialdehyde contents (MDA, 3.3 nmol/dL), and atherogenic index (AI, 2.0) compare to high-fat diet group. These data suggest that TRF supplementation has significant health benefits through the modulation of physiological functions that include various atherogenic lipid profiles and antioxidative status in hyperlipidemia.

This study investigated the effects of onion juice on the serum lipid components and blood pressure in obese rats fed high fat diets. Thirty-nine of Sprague-Dawley rats were divided into six groups, and were treated for 8 weeks: (1) normal diet (ND); (2) high fat diet (HFD); (3) HFD for first 4 weeks and high fat diet with 40% onion juice for the last 4weeks (H-H+O); (4) HFD with 40% onion juice for 8 weeks (H+O); (5) HFD for first 4 weeks and ND for the last 4 weeks (H-N); (6) HFD for first 4 weeks and ND with 40% onion juice for the last 4 weeks (H-N+O). The rates of increasing body weight were reduced in H+O and H-H+O groups compared with HFD group. The levels of triglyceride, low density lipoprotein-cholesterol and total cholesterol in blood serum were significantly decreased in the H+O and H-H+O groups compared with the HFD group. Administration of onion reduced the size of adipocyte, steatosis, and serum hyperlipidemia in obese rats fed HFD. Moreover, the antihypertensive effects of onion were observed in obesity rat fed HFD. Overall results suggest that onion reduces the serum lipid components and improves hypertension in obese rat fed HFD.
