摘    要:目的:制备姜黄素纳米混悬凝胶剂(Cur NS-gel)并考察其对大鼠硒性白内障的治疗作用。方法:采用高压均质法制备姜黄素纳米混悬剂(Cur NS),以卡波姆940为基质制成凝胶剂,分别对其形态、载药量、粒径、电位、胶凝缓冲能力、可滴性、黏度进行检测;采用流通池法测定Cur体外释放行为。实验动物分为空白组,模型组,Cur混悬液组,Cur NS组,Cur NS-gel组,建立硒性白内障大鼠模型,给药体积均为0.25μL·g~(-1),对晶状体浑浊度及相关生化指标进行测定。结果:Cur NS具有类球形形态,粒径(298.2±14.9)nm,Zeta电位(30.7±2.12)m V,制成Cur NS-gel后对其形态、粒径及Zeta电位无显著影响,但黏度提高至(802±15.9)m Pa·s。Cur NS和Cur NS-gel在6 h内Cur体外累计释放率分别为Cur混悬液的26.2倍及18.3倍,且Cur NS-gel具有明显时滞现象。体内药效学结果显示Cur NS-gel可显著延缓晶状体浑浊发展,其总超氧化物歧化酶活力较模型组,Cur混悬液组及Cur NS组显著提高;Cur NS-gel组谷胱甘肽含量分别为Cur混悬液组及Cur NS组的2.1倍及1.5倍(P0.05)。结论:纳米混悬凝胶剂可作为Cur的有效载体,可进一步提高Cur对大鼠硒性白内障的治疗作用。
