Abstract:
Vascular endothelial growth factor (VEGF) is a glycoprotein that promotes endothelial regeneration, stimulates formation of collateral blood vessels and increases vascular permeability. The purpose of this study was to measure the peripheral blood plasma level of VEGF and FT3, FT4, TSH and to analyze the correlation of the level of VEGF and TSH, FT3, FT4, age and gender in the patients of hyperthyroidism. The relationship between hyperthyroidism and VEGF was investigated as well. The plasma level of VEGF in 45 hyperthyroidism patients and 27 healthy persons were measured by enzyme-linked immunosorbent assay (ELISA), while plasma FT3, FT4, TSH were detected by chemiluminescence. The result showed that the plasma level of VEGF in hyperthyroidism patients [(92.53 +/- 62.38) pg/mL] was significantly lower than that in the control group [(158.28 +/- 77.15) pg/mL] (P < 0.01). The plasma level of VEGF correlated with age, and that of those over 40Y was significantly higher than that of 40Y or younger (P < 0.05) in healthy group. Whereas there was no correlation among VEGF, TSH, FT3, FT4, age and gender in hyperthyroidism patients (P > 0.05). These results suggested that the peripheral blood plasma level of VEGF in hyperthyroidism patients was significantly lower than that in the control group. Further experimental investigations are needed to estimate the relationship between VEGF and hyperthyroidism.
