摘要:
objective: 测量葡萄糖摄取到外围组织中的葡萄糖摄取是一种重要的机械机制,以评估胰岛素的重要性。目前进行了一项在体外研究,以评估phyllanthus emblica(PE),Tinospora Cordifolia(TC)和Curcuma Longa(CL)的胰岛素敏化活性,通过评估3T3L1脂肪细胞模型中的葡萄糖吸收活性。材料和方法: 使用胰岛素,异丁基-1-甲基二甲氨酸和右转的鸡尾酒,将3T3 L1成纤维细胞分化为脂肪细胞。这些脂肪细胞最初是用不同浓度的植物处理的,随后使用放射性测定法估计了2-脱氧葡萄糖的摄取。 The effects of plants on glucose uptake both in the presence and absence of insulin was evaluated and compared with pioglitazone, a known insulin sensitizer.
RESULTS: Pe and Tc per se significantly stimulated glucose uptake in 3T3-L1 adipocytes in a dose dependent manner with在较高浓度(200μg/ml)下最大效应。 PE和TC在200μg/mL时的作用与胰岛素相当,大于吡格列酮。 Cl本身刺激葡萄糖吸收,最大作用在50μg/ml时。但是,与高胰岛素相比,这种作用较小R浓度抑制葡萄糖摄取。 When combined with insulin, an antagonist effect was observed between Pe, Tc and insulin indicating a possible plant-drug interaction while Cl in combination with insulin showed an increase in the glucose uptake as compared to Cl alone.
CONCLUSION: The results suggest that one of the mechanisms for the anti-diabetic effect of PE,CL和TC可以通过胰岛素敏化作用(刺激葡萄糖吸收到脂肪细胞中)。使用其他目标站点的进一步研究。骨骼肌和肝细胞模型以及在胰岛素耐药状态下将有助于证实这一结论。
