AIM: To analyze the protective effect of resveratrol on the optic nerve of glaucoma rats and its effect on the phosphatidylinositol 3 kinase(PI3K)/protein kinase B(Akt)signal pathway and its related factors.METHODS: SPF grade SD rats were used to cauterize the scleral surface veins to make a right eye glaucoma model. After successful modeling, different doses(10, 20, 40 mg/kg intraperitoneal injection)of resveratrol were used to intervene. Intraocular pressure was measured 2h after the last administration, and retinal slices were made to observe the survival of retinal ganglion cells(RGC). Retinal plaque to observe the survival of retinal ganglion cells(RGC). Real-time fluorescence quantitative PCR and Western blot were used to detect the mRNA and protein expression of retinal PI3K, Akt, basic fibroblast growth factor(bFGF), and brain-derived neurotrophic factor(BDNF).RESULTS: The intraocular pressure(30.25±4.25)mmHg in the model group was higher than that in the low-dose group(26.30±4.05)mmHg, the middle dose group(22.31±3.68)mmHg and the high dose group(18.32±3.21)mmHg, and the model group RGC labeling rate(48.25±4.50)% was lower than the low dose group(56.32±5.05)%, middle dose group(66.03±6.68)% and high dose group(78.56±7.82)%(P |
