Objective:
To observe the topically hemostatic effects of batroxobin (BX) in different concentrations on the carotid arteries adventitia removal rabbit.
Methods:
18 rabbits were removed vascular adventitia by collagenase digestion and mechanical dissection, causing capillary hemorrhage. Then all of them were randomly divided into 6 groups: blank control, negative control group, 0.5, 1, 2 and 4 kU/L (U/ml) BX group. The hemostatic time and bleeding volume were observed to compare the hemostatic effect of each group. Haematoxylin-eosin, Masson staining and immunohistochemistry were performed to assure adventitia removed.
Results:
It was feasible to remove vascular adventitia with collagenase digestion and mechanical dissection. The hemostatic time and bleeding volume were significantly different (P < 0.05) from 0.5 U/ml BX group [(97 ± 20)s,(0.102 ± 0.013)g/cm(2)] of the negative control group[(143 ± 33)s,(0.130 ± 0.023) g/cm(2)]. With the increase of BX concentration, there was a significant difference (P < 0.05) between 2 U/ml BX group (32 ± 13,0.056 ± 0.015) and 1 U/ml BX group (32 ± 13,0.056 ± 0.015), but there was no statistical significance (P > 0.05) between 2 U/ml BX group and 4 U/ml BX group (28 ± 14,0.053 ± 0.012). Thus, the best topical hemostatic concentration of BX was 2 U/ml.
Conclusion:
The topical hemostatic effect of batroxobin is reliable in small area of blood oozing.
