目的:探讨Leptin对下丘脑外测区(LHA)、腹内侧核(VMH)和室旁核(PVN)的RNA含量和脂肪沉积的影响。方法:通过小鼠注射Leptin,连续注射14 d,70日龄时将动物宰杀,取LHA、VMH和PVN的组织,用荧光显微数字成像系统和Image Pro plus图像分析,测...目的:探讨Leptin对下丘脑外测区(LHA)、腹内侧核(VMH)和室旁核(PVN)的RNA含量和脂肪沉积的影响。方法:通过小鼠注射Leptin,连续注射14 d,70日龄时将动物宰杀,取LHA、VMH和PVN的组织,用荧光显微数字成像系统和Image Pro plus图像分析,测RNA。结果:Leptin引起生长期小鼠LHA和VMH的RNA含量显著增高(P<0.01、P<0.05),PVN的RNA含量降低,腹腔脂肪沉积显著减少(P<0.05)。结论:Leptin能引起LHA和VMH的功能加强,且两者都均与腹腔脂肪沉积呈负相关。展开更多
