Abstract:

Aim:
This study was to investigate the anti-angiogenic effect of hexahydrocurcumin (HHC) to evaluate gene (p-basic fibroblast growth factor (bFGF)-SAINT-18 & p-vascular endothelial growth factor (VEGF)-SAINT-18 complex)-induced corneal neovascularization (CorNV) in rats.
Methods:
CorNV was induced in 24 eyes of 24 rats. Four groups (Group A: 0 μg, B: 0.01 μg, C: 0.1 μg, and D: 1 μg) of HHC were prepared and implanted into the rat subconjunctival substantia propria 1.5 mm from the limbus at temporal side. The 1 μg of p-bFGF-SAINT-18 & p-VEGF-SAINT-18 complex were prepared and implanted into the rat corneal stroma 1.5 mm from the limbus at the same side. Inhibition of CorNV was observed and quantified from day 1 to day 60. bFGF and VEGF protein expression were analyzed by biomicroscopic examination, western blot analysis, and immunohistochemistry.
Results:
Subconjunctival injection by 1 μg HHC successfully inhibited gene-induced CorNV in rats. bFGF and VEGF protein expression were reduced after 6 days. Meanwhile, the reduction of HLA-DR expression was detected.
Conclusions:
Our study showed that the HHC might provide an important anti-angiogenesis factor to inhibit CorNV development at the corneal experimental angiogenesis model.
