| 目的 研究吡罗美拉汀(Neu-P11)对急性高眼压兔眼内压的影响。方法采用特伦德伦伯卧位法建立急性高眼压模型兔。建模后将33只急性高眼压新西兰大白兔分为局部给药组和全身给药组,给予生理盐水,褪黑素(Mel)和不同剂量的Neu-P11处理,局部给药通过眼角膜滴注固定体积(10 μL)药物进行给药,全身给药通过灌胃固定体积(1 mL)药物进行给药,给药后平位休息2 h,然后再次置于卧位45 min,平位每小时测量一次眼内压,连续监测6 h,重复实验一周。结果新西兰大白兔经Trendelenburg卧位诱导后,眼内压约升高为正常组的1.9倍。局部给药组经Neu-P11和Mel治疗后眼内压明显降低(P<0.05),且Neu-P11低浓度治疗组比高浓度组效果更佳。全身给药组Neu-P11和Mel均可明显降低眼内压,且Neu-P11对眼压的影响存在剂量依赖性,Neu-P11浓度越高眼内压下降速度越快。结论Neu-P11和褪黑素均具有降低急性高眼压兔眼内压的作用。 |

| Objective To investigate the effect of piromelatine (Neu-P11) on intraocular pressure (IOP) in acute high IOP rabbits.MethodsThe experiment used the Trendelenburg position to establish acute high IOP rabbit model.33 New Zealand white rabbits with IOP were divided into local treatment group and systemic treatment group.Local or systemic treatment group were treated with saline,melatonin(Mel) and different concentrations of Neu-P11.The fixed volume (10 μL) was dropped into the cornea in local treatment.The systemic treatment was administered by filling the stomach with drug of fixed volume (1 mL).Rest 2 hours after treatment in the flat supine position,then rabbits were placed in the Trendelenburg position for 45 min.And then,put rabbits in normal position and measured IOP every hour for 6 hours.Repeat the experiment for a week.ResultsIOP could increase about 1.9 times in the Trendelenburg position of New Zealand white rabbit (vs Normal group).Namely acute high IOP model was successfully established.IOP on local treatment with 100/200 μmol/L Neu-P11 or 100 μmol/L Mel significantly declined and the effect of 100 μmol/L Neu-P11 was better than 200 μmol/L Neu-P11.Similarly,IOP on local treatment with Neu-P11 and Melatonin could also be reduced,and the treatment of Neu-P11 was dose dependent,the higher the concentration of Neu-P11 was,the faster IOP declined.ConclusionsNeu-P11 and Melatonin could significantly reduce IOP of the acute high intraocular pressure rabbit. |
