ABSTRACT
OBJECTIVE@#To investigate the effects of serum from crush injury rats on vascular endothelial cell apoptosis and their potential mechanism.@*METHODS@#Bovine aorta endothelial cells were cultured in vitro and the effects of serum from crush injury rats on cell apoptosis and intracellular calcium concentration ([Ca2+]i) were observed. Meanwhile, the levels of rat blood plasma endothelin-1 (ET-1) and atrial natriuretic peptide(ANP) were measured.@*RESULTS@#Compared with normal rat serum treatment, the cell apoptosis rate decreased from (8.26+/-1.75)% to (2.75+/-0.90)%, while the concentration of [Ca2+]i increased from (96.98+/-3.95) to (118.79+/-3.22) nmol/L in serum from crush injury rats, respectively. The concentration of ET-1 and ANP increased significantly in crush injury rat serum.@*CONCLUSION@#Serum from crush injury rats could inhibit apoptosis of the vascular endothelial cells. These effects may be related to increased level of [Ca2+]i mediated by ET-1 and ANP.
