摘    要:目的探讨一氧化氮(nitricoxide,NO)在青光眼患者眼压升高中的作用.方法对急性闭角型青光眼患者16例,老年性白内障患者29例,正常志愿者30例,应用高效液相色谱分析仪检测其血浆和房水中NO的含量,并以NO2和NO3之和表示.结果正常对照组血浆中NO的平均含量为(2969.37±862.85)ng/L;青光眼组血浆中NO的平均含量为(1390.78±302.95)ng/L,较对照组明显降低(t=2.853,P<0.01);白内障组血浆中NO的平均含量为(4234.89±1495.23)ng/L,较对照组明显升高.对照组房水中NO平均含量为(1405.83±602.70)ng/L;青光眼组房水中NO的平均含量为(2052.03±694.74)ng/L,与对照组比较差异无显著性(t=1.862,P>0.05);白内障组房水中NO的平均含量为(2454.67±655.13)ng/L,较对照组明显升高.房水/血浆NO含量比值对照组为47.3%,白内障组为58.0%,二者的比值差异无显著性;而青光眼组为144.0%.结论血浆、房水中NO含量与急性闭角型青光眼眼压升高有关.

Abstract:OBJECTIVE: To investigate the role of nitric oxide (NO) in the process of intraocular pressure (IOP) elevation in glaucoma. METHODS: The levels of NO in plasma and in aqueous humor which were obtained from 16 patients with acute angle closure glaucoma (10 female, 6 male), 29 cases with cataract (13 female, 16 male) and 30 normal volunteers (13 female, 17 male) were detected by high performance liquid chromatography and expressed with the total NO(2) and NO(3). RESULTS: It was found that the mean level of NO in the plasma in glaucoma group was (l,390.78 +/- 302.95) ng/L that was significantly lower than that in the normal group (2 969.37 +/- 862.85) ng/L (t = 2.853, P < 0.01). But in cataract group it was (4,234.89 +/- 1,495.23) ng/L that was significantly higher than that in the normal group (t = 4.471, P < 0.01). There was no significant difference in the level of NO in the aqueous humor between glaucoma group (2,052.03 +/- 694.74) ng/L and normal group (1,405.83 +/- 602.70) ng/L (t = l.862, P > 0.05). But in cataract group the mean level of NO (2, 454.67 +/- 655.13) ng/L in the aqueous humor was increased remarkably in comparison with that in the normal group (t = 2.752, P < 0.01). The rate of the mean content of NO in normal aqueous humor and plasma (aqueous/plasma) was 47.3%, and that in cataract group, 57.96% (P > 0.05). But in glaucoma group, the rate was 144.0%. CONCLUSION: The content of nitric oxide in the plasma and aqueous humor is related to the elevation of IOP in cases with acute angle closure glaucoma.
