| Abstract | Objectives: To study the effects of grape seed proanthocyanidins (GSP) combined with allicin on serum lipids level and vascular damage in a rat model of hyperlipidemia. Materials and methods: SD rats(male, 170-220 gn= 40) were randomized into five groups (n = 8/group): modelhigh fat and cholesterol diet; controlnormal diet; model+low-dose (GSP+allicin )(GSP 45mg/kg, allicin 30mg/kg, orally); model+high-dose (GSP+allicin) (GSP180mg/kg, allicin 90mg/kg, orally) and positive control (model+simvastatin (4 mg/kg)). Normal control group was fed conventionally, and remaining four groups were fed high cholesterol and fat food to replicate the high fat model. After 9 weeks, the normal control group continued to receive regular feeding, while the other groups continued to receive high-fat feeding. At the same time, model and normal control groups were given equal volume of physiological saline by gavage, and the other treatment groups began to receive corresponding drugs by gavage once a day. After 4 weeks, serum levels of total cholesterol (TC), triglyceride (TG), low density lipoprotein cholesterol (LDL-C) as well as high-density lipoprotein cholesterol (HDL-C) in rats were determined. And the body weight of rat, total antioxidant capacity (T-AOC), superoxide dismutase (SOD) and malondialdehyde (MDA)in serum were identified. The level of endothelin-1(ET-1) was quantitative analysis by ELISA assay. Results: In comparison to normal controls, the model group displayed a marked rise in body weight, an increment in serum concentrations of LDL-C, TG and TC, as well as a decline in HDL (P<0.01), demonstrating successful model replication; All doses of GSP in combination with allicin resulted in a reduction in TG, LDL-C, and TC and an enhancement in HDL-C in contrast to the model control (all P<0.05). High-dose (GSP+allicin ) decreased MDA, and increased T-AOC and SOD activity(all P<0.01). All doses of GSP combined with allicin decreased ET-1 (all P<0.05). In addition, the protective effect of GSP combined with allicin was dose-dependent. Conclusions: Studies have shown that GSP combined with allicin can significantly improve blood lipids in hyperlipidemic rats, and this mechanism may be related to antioxidants and reduced endothelial damage. |
