目的 :比较含有玻璃酸钠的硫酸庆大霉素滴眼液 (样品 )和硫酸庆大霉素滴眼液 (对照 )在兔眼结膜囊冲洗液中的浓度。方法 :用荧光光度法分别于 5 ,15 ,30和 6 0min时测定结膜囊冲洗液中样品和对照的浓度。结果 :在 6 0min内样品的浓度明显高于对照 (P <0 .0 1)。结论 :样品在结膜囊中能保持较高浓度和维持较长时间
OBJECTIVE: To compare the concentrations of sodium hyaluronate sodium gentamicin sulfate eye drops (samples) and gentamicin sulfate eye drops (control) in rabbit conjunctival sac washings. Methods: The concentrations of samples and controls in the conjunctival sac washings were measured by fluorescence spectrophotometry at 5, 15, 30 and 60 minutes respectively. Results: The concentration of the sample in 60 min was significantly higher than that in the control (P <0.01). Conclusion: The sample can maintain a high concentration in the conjunctival sac and maintain a long time
