摘要: 目的: 观察红杉醇对2型糖尿病大鼠脂代谢的影响。方法: 采用高糖高脂饮食加腹腔注射小剂量链脲佐菌素(Streptozotocin,STZ)诱导2型糖尿病大鼠模型35只,灌服红杉醇(50、25及 12.5 mg·kg-1·d-1)6周,每天1次。全自动生化分析仪测定血清TG、TC、低密度脂蛋白胆固醇(Low density lipoprotein cholesterol,LDL-C)含量;ELISA法检测血浆游离脂肪酸(Free fatty acids,FFA)、肝脏载脂蛋白A1(Apolipoprotein A1,Apo-A1)和载脂蛋白B1(Apolipoprotein B1,Apo-B1) 含量;放射免疫法测定肝组织瘦素(Leptin)含量;MASSON染色观察肝脏病理改变。结果: 红杉醇能显著降低模型大鼠血脂、FFA含量,下调肝组织Apo-B1及Leptin水平,上调肝组织Apo-A1的含量,减轻肝细胞脂肪变性,减少肝细胞间质和血管旁胶原沉积。结论: 红杉醇具有调节2型糖尿病大鼠脂代谢、减轻脂肪肝和肝脏胶原沉积的作用。

Abstract: AIM: To observe the effects of sequoyitol on lipid metabolism in rats with type 2 diabetes.METHODS: Type 2 diabetic rats were induced by fed with a high fat and high sugar diet as well as injected with a low dosage of streptozotocin (35 mg/kg). Sequoyitol (12.5, 25, 50 mg·kg-1·d-1) was orally administered once a day in 35 model rats for 6 weeks. The contents of TG, TC, and low density lipoprotein cholesterol (LDL-C) were measured using fully automatic biochemical analyzer. ELISA was used to measure the contents of free fatty acids (FFA) in plasma,and the levels of apolipoprotein A1 (Apo-A1) and apolipoprotein B1(Apo-B1) in liver tissues. The content of leptin was measured with radioimmunoassay. In addition,pathological changes in liver was observed with MASSON staining.RESULTS: Sequoyitol reduced the contents of blood lipids,FFA,Apo-B1 and leptin,elevated the content of Apo-A1. At the same time,sequoyitol ameliorated hepatocellular fatty degeneration, reduced collagen deposition at liver cell interstitial and next to the blood vessels.CONCLUSION: The results show that sequoyitol regulates lipids metabolism and inhibites hepatic steatosis and collagen deposition in type 2 diabetes rats.
