摘 要:目的观察联合应用甘油果糖和碳酸酐酶抑制剂对急性高眼压大鼠眼组织水通道蛋白1(AQPl)表达的影响。方法建立高眼压大鼠模型,并使用甘油果糖和碳酸酐酶抑制剂对高眼压大鼠模型鼠进行干预,检测房角组织AQPl的基因及蛋白表达水平。结果高眼压大鼠房角组织AQPl的基因和蛋白表达水平(造模后1、6、24、48、72h:1.55±0.02、2.22±0.03、2.46±0.02、1.88±0.04、1.44±0.03;1.21±0.02、3.58±0.03、3.81±0.02、4.28±0.04、4.44±0.03)均显著高于对照组(1.00±0.00、1.00±0.00,P均〈0.05)。碳酸酐酶抑制剂可抑制高眼压大鼠房角组织AQP1的基因和蛋白表达水平的增高(高眼压模型组vs.碳酸酐酶抑制剂组:1.41±0.02VS.1.24±0.04;4.41±0.02 vs.2.31±0.04,P均〈0.05j,碳酸酐酶抑制剂与甘油果糖联合使用后,抑制效果更加明显(高眼压模型组vs.甘油果糖联合碳酸酐酶抑制剂组:1.41±0.02 vs.1.08±0.03;4.41±0.02VS.1.47±0.03,P均〈0.05)。结论高眼压可使AQPl表达升高,而联合使用甘油果糖与派立明可降低AQP1的表达。Objective To observe the effect of glye-fructose combined with carbonic anhydrase inhibitor ( CAI ) on the expression of AQP 1 in rat eyes. Methods The model of intraocular hypertension in rats were established, and intervention on intraocular hypertension model rats were performed using glyc- erol fructose and carbonic anhydrase inhibitors. The expression of AQP 1 in the chamber angle tissue was detected in the mRNA and protein level. Results The expression of AQP 1 in the intraocular hypertension group ( 1 , 6, 24, 48 and 72 h) was significantly higher than those in the control group ( 1. 55 ±0.02, 2.22±0.03, 2.46±0.02, 1.88±0.04, 1.44±0.03; 1.21±0.02, 3.58±0.03, 3.81±0.02, 4.28±0.04, 4.44 ±0.03, all P〈0.05). Carbonic anhydrase inhibitors could in hibit the expression of AQP 1 in the chamber angle tissue of the intraocular hypertension model rats ( intraocular hypertension group vs. CAI group: 1.41±0.02 vs. 1.24±0.04; 4.41±0.02 vs. 2.31 ± 0.04, all P 〈 0.05 ) . The combined use of glyc-fructose with CAI could inhibit the expression more ob- viously( intraocular hypertension group vs. Glyc-fructose combined with CAI group: 1. 41 ± 0.02 vs. 1.08±0.03; 4.41±0.02 vs. 1.47±0.03, all P 〈 0.05). Conclusion The expression of AQPI was elevated in the intraocular hypertension group, and co-administrated with glycerol fructose and brinzolamide could inhibit the expression.
