摘要 目的建立体外血脑屏障(BBB)模型,考察血栓通的主要活性成分(人参皂苷Rb1、人参皂苷Rd、人参皂苷Re、人参皂苷Rg1及三七皂苷R1)的通透性。方法选用小鼠脑微血管内皮细胞株bEnd.3建立体外BBB模型。然后分为正常组和模型组,正常组培养6 h,模型组缺氧6 h后,均给予50μg·m L^(-1)血栓通0.2 m L。给药4 h后,用高效液相色谱/质谱联用法测定各组的各有效成分的通透系数。结果正常组中,人参皂苷Rg1、人参皂苷Rb1、人参皂苷Rd、人参皂苷Re、三七皂苷R1的通透系数分别为(70.37±5.78)×10^(-8),(102.36±69.21)×10^(-9),(0.57±0.38)×10^(-9),(98.96±15.52)×10^(-9),(382.18±42.49)×10^(-9)cm·s^(-1);模型组中,这5种活性成分的通透系数分别为(116.20±21.80)×10^(-8),(555.40±202.65)×10^(-9),(2.96±1.43)×10^(-9),(202.66±37.5)×10^(-9),(634.26±124.40)×10^(-9)cm·s^(-1)。与正常组相比,模型组的通透系数显著增加,差异有统计学意义(P<0.05)。结论血脑屏障缺氧6 h后明显开放,注射用血栓通(冻干)可以透过血脑屏障发挥神经保护作用。 Objective To study the permeability of the main active ingredients of Xueshuantong Injection( Lyophilized powder),such as Ginsenoside Rb1,Ginsenoside Rd,Ginsenoside Re,Ginsenoside Rg1 and Notoginsenoside R1 by establishing the blood brain barrier( BBB) in vitro. Methods The b End. 3 was used to establish the BBB in vitro,which consisted of normal group and model group. After normal culture 6h in normal group and oxygen glucose deprivation( OGD) 6 h in model group,these groups were given 50 μg·m L^-1Xueshuantong Injection 0. 2m L to culture 4 h. The Pappof the main active ingredients in each group were measured by using a liquid chromatography tandem mass spectrometry( LC- MS / MS). Results The Pappof the Ginsenoside Rb1,Ginsenoside Rd,Ginsenoside Re,Ginsenoside Rg1 and Notoginsenoside R1 in normal group were( 70. 37 ± 5. 78) × 10(- 8),( 102. 36 ± 69. 21) × 10^-9,( 0. 57 ±0. 38) ×10^-9,( 98. 96 ±15. 52) ×10^-9,( 382. 18 ±42. 49) ×10^-9cm·s^-1. The Pappof the Ginsenoside Rb1,Ginsenoside Rd,Ginsenoside Re, Ginsenoside Rg1 and Notoginsenoside R1 in model group were( 116. 20 ±21. 80) × 10^(- 8),( 555. 40 ± 202. 65) × 10^-9,( 2. 96 ± 1. 43) ×10^-9,( 202. 66 ± 37. 5) × 10^-9,( 634. 26 ± 124. 40) × 10^-9cm · s^-1.The Pappof the model group was significant higher than that of normal group( P〈0. 05). Conclusion After b End. 3 OGD 6 h,the BBB opens,and Xueshuantong Injection( Lyophilized powder) can exertneuroprotective effects across the blood brain barrier.
