Abstract:
Objective: To investigate the protective effects of different storage solutions on the ultrastructure and integrity of rabbit endothelial cells, and their effects on endothelin 1 secretion. Methods: Femoral artery segments were harvested from 16 adult rabbits, which were then stored separately in four different storage solutions. The solutions was: (1) verapamil nitroglycerin solution (VG); (2) heparinized papaverine autologous blood (PB); (3) papaverine solution (PS); (4) Ringer's solution (Ringer). The ultrastructure of the endothelial cells,the covering percentage of endothelium monolayer and the level of endothelin 1 secretion were evaluated. Results: The covering percentage of endothelium monolayer was significantly higher in VG [(69?10)%] and PB[(71?9)%] compared with that in Ringer [(55?11)%] (P0.05). The endothelial ultrastructure was more seriously damaged in PS than that in VG and in PB through TEM. The level of endothelin 1 secreting was similar significantly increased only in PB [(116.781?22.387) pg/ml] compared with that in Ringer (P
