摘要: 为研究黄芪甲苷(Astragaloside IV,AS-Ⅳ)在正常小鼠(db/m)和2型糖尿病肾病(db/db)小鼠体内的组织分布差异,为AS-Ⅳ抗2型糖尿病肾病的临床运用及新药研发提供实验依据。以尾静脉注射给予2型糖尿病肾病(db/db)和正常小鼠(db/m)小鼠AS-Ⅳ,剂量为8 mg/kg。于15 min、2 h、4 h时处死小鼠,收集心、肝、脾、肺、肾、胃、小肠、脑、肌肉组织,采用HPLC-MS/MS法测定各组织中AS-Ⅳ含量,对比AS-Ⅳ在正常及病理状态下,在各组织中的分布差异。在2型糖尿病肾病状态下,AS-Ⅳ在肝、脾、肺、肾组织中浓度分别为349.72±70.72、370.69±45.46、5 830.65±581.75、4 290.63±485.34 ng/mL;正常状态下,AS-Ⅳ在肝、脾、肺、肾组织中浓度分别为202.47±47.96、267.92±41.24、4 725.80±867.51、2 354.55±256.11 ng/mL,在2型糖尿病肾病状态下,AS-Ⅳ在肝、脾、肺、肾组织中浓度显著高于其在正常组织中浓度(P<0.05)。静脉注射给药后,肺、肾、心、胃、脾是其主要分布器官,其中在肺、肾组织中浓度最高;病理状态下,AS-Ⅳ组织分布发生了一定改变,为AS-Ⅳ防治2型糖尿病肾病的临床合理应用及开发提供实验依据。

Abstract: To study Astragaloside Ⅳ(AS -Ⅳ) in normal mice (db/m) and type 2 diabetic nephropathy (db/db) mice in vivo tissue distribution difference,the purpose of this study was to provide experimental basis for the clinical application of AS-Ⅳagainst type 2 diabetic nephropathy and new drugs research and development. Normal mice (db/m) and type 2 diabetic nephropathy (db/db) mice were injected intravenously with AS-Ⅳ 8 mg/kg dose,the mice were killed at 15 min,2 h and 4 h,to collect heart,liver,spleen,lung,kidney,stomach,intestine,brain,muscle tissues.The content of AS-Ⅳ in each tissues were determined by HPLC-MS/MS,and the distribution of AS-Ⅳ in each tissues under normal and pathological conditions was compared.In type 2 diabetic nephropathy,the concentrations of AS-Ⅳ in liver,spleen,lung and kidney were 349.72±70.72,370.69±45.46,583.65±581.75,4290.63±485.34 ng/mL.In the normal state,the concentrations of AS-IV in liver,spleen,lung and kidney were 202.47±47.96,267.92±41.24,472.80±867.51,234.55±256.11 ng/mL,respectively.The concentration of AS-Ⅳ in liver,spleen,lung and kidney was significantly higher than that in normal tissues(P<0.05).After intravenous injection,lung,kidney,heart,stomach and spleen were the main distribution organs,and the concentration was the highest in lung and kidney.Under the pathological condition,the tissue distribution of AS-Ⅳ changed to a certain extent,which provided an experimental basis for the clinical rational application and development of AS-Ⅳ in the prevention and treatment of type 2 diabetic nephropathy.
