藻酸双酯钠具有抗凝、抗血栓以及调节血脂等作用,是一种新型的抗动脉粥样硬化药物.但它对糖尿病伴脂代谢异常血症的治疗作用还没有明确.本研究建立糖尿病伴脂代谢异常血症大鼠模型,初步探讨藻酸双酯钠对其血糖和血脂的调节作用.Wistar大鼠高脂饲料喂养1.5个月后尾静脉注射链脲佐菌素.建模成功后,灌胃给予藻酸双酯钠1个月,检测血中血糖、胰岛素和脂质浓度.结果显示,藻酸双酯钠治疗组与糖尿病对照组相比,血中甘油三酯、总胆固醇和低密度脂蛋白明显降低,高密度脂蛋白显著升高,藻酸双酯钠治疗后血糖和胰岛素浓度有所下降,而胰岛素敏感指数比糖尿病对照组明显提高.本研究提示,藻酸双酯钠可以改善糖尿病伴脂代谢异常血症大鼠血脂异常,并提高胰岛素敏感性.
藻痠雙酯鈉具有抗凝、抗血栓以及調節血脂等作用,是一種新型的抗動脈粥樣硬化藥物.但它對糖尿病伴脂代謝異常血癥的治療作用還沒有明確.本研究建立糖尿病伴脂代謝異常血癥大鼠模型,初步探討藻痠雙酯鈉對其血糖和血脂的調節作用.Wistar大鼠高脂飼料餵養1.5箇月後尾靜脈註射鏈脲佐菌素.建模成功後,灌胃給予藻痠雙酯鈉1箇月,檢測血中血糖、胰島素和脂質濃度.結果顯示,藻痠雙酯鈉治療組與糖尿病對照組相比,血中甘油三酯、總膽固醇和低密度脂蛋白明顯降低,高密度脂蛋白顯著升高,藻痠雙酯鈉治療後血糖和胰島素濃度有所下降,而胰島素敏感指數比糖尿病對照組明顯提高.本研究提示,藻痠雙酯鈉可以改善糖尿病伴脂代謝異常血癥大鼠血脂異常,併提高胰島素敏感性.

Polysaccharide sulfate (PSS) is a new type of antiatherosclerotic medicine for its effects of anticoagulation, anti-thrombosis and modulation of dyslipidemia. However, it is still uncertain whether PSS could modulate the diabetic dyslipidemia or not. Here, the rat model of diabetic dyslipidemia was developed and the effects of PSS on glucose and lipid levels were investigated in this animal model. Wistar rats were iv injected with streptozotocin 20 mg·kg-1 after feeding with high fat diet for one and a half month. Then, rats received orally PSS (30, 90, and 180 mg·kg-1) for 1 month. After oral treatment with PSS (90 and 180 mg·kg-1) for 1 month, the levels of triglyceride (TG), total cholesterol (TC), low density lipoprotein-cholesterol (LDL-C) were significantly reduced and the level of high density lipoprotein-cholesterol (HDL-C) increased, compared with diabetic control rats. Moreover, PSS (30, 90, and 180 mg·kg-1) had a tendency to reduce glucose and insulin levels, and significantly increased insulin sensitivity index. Our results suggest that PSS could improve insulin sensitivity and relieve dyslipidemia in diabetic dyslipidemic rats.
