简介：目的比较两种不同药物低分子肝素钠与肝素钠皮内注射治疗眼睑黄色瘤的疗效分析。方法将34例眼睑黄色瘤患者（28例双眼,6例单眼）,等分成两组（每组14例双眼,3例单眼）：低分子肝素钠组瘤体面积（32.06±11.20）mm^2,肝素钠组瘤体面积（31.68±10.34）mm^2（t=-0.164,P=0.871）,两组间瘤体大小差异无统计学意义。两组均严格采取皮内注射方法,一组皮内注射低分子肝素钠,另一组则皮内注射肝素钠,观察其疗效和疗程以及不良反应和并发症。结果两种药物皮内注射均能取得满意的临床疗效,但低分子肝素钠见效快、疗程短,且皮下淤血发生率明显降低。结论低分子肝素钠皮内注射治疗眼睑黄色瘤具备更优的临床效果。

简介：目的：研究家兔静脉注射头孢哌酮钠／舒巴坦钠在眼内的透过性及蓄积作用。方法：用高效液相色谱法（highperformanceliquidchromatography，HPLC）测定给药后不同疗程时间点各组兔眼房水和玻璃体中的药物浓度。结果：房水中舒巴坦钠的药物浓度分别为23．4±4．8和23．6±3．7mg／L；头孢哌酮钠浓度分别为8．9±1．2和8．9±1．7mg／L；玻璃体中舒巴坦钠浓度分别为71．2±4．6和69．3±6．8mg／L，头孢哌酮钠未检出。结论：头孢哌酮Ca／舒巴坦钠静脉注射后在正常的眼内透过性不良。
