1Department of Ophthalmology, Fujian Provincial People's Hospital, Fuzhou 350004.
Objective:
To study the roles of tumor necrosis factor (TNF-alpha) and platelet-derived growth factor (PDGF) in pathogenesis of pterygium.
Methods:
Radioimmunoassay and bioactivity assay were used to measure the levels of TNF-alpha and PDGF in tissue culture supernatant of pterygium specimens obtained from 30 patients.
Results:
The levels of TNF-alpha and PDGF in tissue culture supernatant of pterygium were significantly higher than that of normal conjunctival specimens (t = 2.827, P < 0.01; t = 3.011, P < 0.01), and there was a significant difference between progressive and quiescent cases (t = 2.374, P < 0.05; t = 2.712, P < 0.05).
Conclusions:
The abnormal secretion of TNF-alpha and PDGF may be related to the pathogenesis of pterygium.
