Experimental study on vascular injury and repair induced by alternate intravenous instillation of amiodarone in rabbits marginal ear vein
To explore the effects of alternate intravenous instillation of amiodarone on the Vascular injury and repair of rabbit marrginal ear vein.
Methods
2
Ninety large-eared white rabbits were selected as experimental subjects and randomly divided into groups A, B and C, with 30 rabbits in each group. The samples of group A were collected immediately after the completion of the infusion, the samples of group B were collected 72 hours after the completion of the infusion,and the samples of group C were collected 1 week after the completion of the infusion. Each group was further randomly divided into 6 subgroups,namely,1-hour group,2-hour group,3-hour group,4-hour group,5-hour group and 6-hour group,with 5 rabbits in each group,and amiodarone was instilled into the other side of the margin ear vein every 1 hour,2 hours,3 hours, 4 hours, 5 hours and 6 hours.The degree of phlebitis of ear margin was observed. ELISA was used to detected the C-reactive protein (CRP) concentration.HE staining was used to determine the degree of inflammation.TUNEL was used to detect the apoptosis level of vascular endothelial cells.
Results
2
In group A, there was no visible change in the margin ear vein of rabbit in the 1- to 4-hour groups; the infusion site of 1 large-eared white rabbit in 5-hour group was red and swollen, while the blood vessel of 1 large-eared white rabbit in 6-hour group was slightly stringlike. The was no statistically significant difference in C-reactive protein (CRP) concentration among the 1 h, 2 h, and 3 h groups of group A (
P
>
0.05);and the CRP concentrations gradually increased in the 4-hour, 5-hour, and 6-hour groups (
P
<
0.05). The results of HE staining and TUNEL staining showed that the vascular inflammatory injury was minimal within 4 hours in group A,while the inflammatory injury gradually aggravated from 4 hours onwards,and the endothelial cell apoptosis also significantly increased.In group B, injury inflammatory and cell apoptosis were improved after 72 hours of repair. In group C, the degree of vascular inflammatory injury and cell apoptosis further improved after 1 week of repair.
Conclusion
2
Alternate intravenous instillation of amiodarone has the least injury to the vein within 4 hours,and the lightest degree of apoptosis of endothelial cells in rabbit margin ear vein;therefore,the best alternate time is recommended to be within 4 hours.
