[Effects of naoyian serum on VEGF protein expression in cultured rat cerebral microvascular endothelial cell with hypoxia].

Objective: To determine the effects of naoyian (NYA) serum on the expression of vascular endothelial growth factor (VEGF) protein in cultured rat cerebral microvascular endothelial cell (RCMEC) with hypoxia.

Methods: NYA serum was separated from rat heart which had been filled stomach with NYA successively for 3 days. The rat cerebral microvascular endothelial cells were taken from the Sprageu-Dawley rat brain at postborn 7 days.
