Résumé
Aim To establish a model of the vascular endothelial cell (VEC) injury in SDrats.Methods SD rats were randomly divided into the control and the modelgroups. The model rats were injected with adrenaline diluted to 2. 5 times 0. 05 mg?100 g-1 (tid) for 5 d continously. From the 4th d, they were irritated for 5 min in the0℃ cold-water in the middle between adrenaline injections.The control rats weregiven 0. 9% NS as above. At 6th d, blood samples were taken from carotid arteries ofthe rats and the CEC counts, t - PA、PAI activities, 6-keto-PGF1? concentrations andthe platelet aggregation rate(max) were detected respectively. Results In the modelgroup, as compared with those in the control group, t - PA activity and 6-keto-PGF1?concentration decreased significantly(P
