TITLE:
摘要: 目的:研究冰片对积雪草苷透过大鼠血脑屏障的影响。方法:144只SD大鼠随机均分为4组,每组36只。A组,ig积雪草苷30 mg/kg;B组,尾iv积雪草苷30 mg/kg;C组,ig冰片100 mg/kg+ig积雪草苷30 mg/kg;D组,ig冰片100 mg/kg+尾iv积雪草苷30 mg/kg。采用高效液相色谱法测定给药后15、30、60、90、180、300 min各组大鼠脑组织中积雪草苷浓度, 用DAS 2.0软件计算药动学参数。结果:A组大鼠脑组织未检出积雪草苷,B、C、D组大鼠的cmax分别为(0.61±0.03)、(0.85±0.08)、(0.99±0.08) mg/L, AUC0-300 min分别为(55.39±2.71)、(89.88±7.30)、(92.24±9.24) μg·min/ml, AUC0-∞分别为(58.52±2.75)、(92.90±7.08)、(93.16±8.62) μg·min/ml,其中C、D组大鼠的cmax、AUC0-300 min、AUC0-∞均显著高于B组(P<0.05或P<0.01)。结论:冰片可促进积雪草苷透过大鼠血脑屏障,增加其在脑组织中的药物浓度。
ABSTRACT: OBJECTIVE: To study the effects of borneol on the penetration of asiaticoside through the blood brain barrier in rats. METHODS: 144 SD rats were randomly divided into 4 groups,36 for each group. Group A was given asiaticoside 30 mg/kg intragastrcally; group B given asiaticoside 30 mg/kg via tail vein; group C given bornel 100 mg/kg intragastrcally and asiaticoside 30 mg/kg intragastrcally; group D given bornel 100 mg/kg intragastrcally and asiaticoside 30 mg/kg via tail vein. The concentrations of asiaticoside in brain tissue were determined by HPLC at 15, 30, 60, 90, 180, 300 min after medication, and pharmacokinetic parameters were calculated by DAS 2.0 software. RESULTS: Asiaticoside was not found in group A. The pharmacokinetic parameters of group B, C and D were that cmax were (0.61±0.03), (0.85±0.08), (0.99±0.08) mg/L; AUC0-300 min were (55.39±2.71), (89.88±7.30), (92.24±9.24) μg·min/ml; AUC0-∞ were (58.52±2.75), (92.90±7.08), (93.16±8.62) μg·min/ml, respectively. cmax, AUC0-300 min and AUC0-∞ of group C and D were obviously higher than those of group B (P<0.05 or P<0.01). CONCLUSIONS: Borneol can enhance the penetration of asiaticoside through blood brain barrier of rats, so as to increase the concentration of asiaticoside in the brain tissue.
