摘  要:目的研究天麻素(GAS)对大鼠胰岛素瘤细胞(INS-1)的影响,及其对链脲佐菌素(STZ)损伤INS-1细胞的保护和修复作用。方法实验分正常对照组(NC),天麻素组(GAS),STZ损伤组(STZ),天麻素保护组(GAS+STZ)和天麻素修复组(STZ+GAS)。INS-1细胞传代培养后,用四氮唑蓝(MTT)法测定细胞活力,放免法测定胰岛素分泌量,比色法测定丙二醛(MDA)含量和总抗氧化能力(T—AOC)。结果GAS可促进INS-1细胞分泌胰岛素(P〈0.05,P〈0.01),低浓度GAS可增强INS-1细胞活力(P〈0.01);GAS可提高STZ损伤的INS-1细胞活力(P〈0.01),高浓度的GAS对STZ损伤的INS-1细胞具有修复作用,可促进胰岛素的分泌(P〈0.01);GAS可降低STZ损伤的INS-1细胞的MDA含量(P〈0.01),提高STZ损伤的INS-1细胞的T.AOC(P〈0.01)。结论GAS能够增强INS-1细胞活力,促进胰岛素分泌,减轻STZ对INS-1细胞的损伤,提高STZ损伤的INS-1细胞的抗氧化能力。Objective To study effects of gastrodine (GAS) on insulinoma (INS-1) cells and the protection of INS-1 ceils from steptozotocin (STZ) injury by gastrodine. Methods The experiment was carried out in 5 groups: normal control group (NC), GAS group (GAS), streptozotocin group (STZ), GAS protection group (GAS + STZ) and GAS repair group (STZ + GAS). INS-1 cells were cultured, the cell viability was determined by tetrazolium (MTF) assay, insulin concentration was detected by radioimmunoassay, and malondialdehyde (MDA) concentration and total antioxidant capacity (T-AOC) of the culture medium were measured by colorimetry. Results GAS promoted insulin release of INS-1 cells (P 〈 0.05, P 〈 0.01 ). Low-concentration GAS could increase viability of INS-1 cells (P 〈 0.01 ). GAS could increase viability of the injured INS-1 cells (P 〈 0.01 ). High concentration GAS contributed in repair of INS-1 ceils injured by STZ and promoted insulin serection ( P 〈 0.01 ). GAS could decrease MDA concentration (P 〈0.01 ) and significantly increase T-AOC capacity of INS-1 cells injured by STZ (P 〈 0.01 ). Conclusions GAS can increase INS-1 viability, promote insulin secretion of INS-1 cells, alleviate INS-1 cells injury caused by STZ, and strengthen the antioxidant capacity of INS-1 cells injured by STZ.
