Objective:
To compare the development of thrombosis animal model induced by endotoxin(LPS) in combination with carrageenan (Ca) in different animals.
Method:
Two species of rats (SD and Wistar) and three species of mice (Kunming, ICR and Balb/c mice) were employed in the study. The animals of each species were randomly divided into control group and model group (LPS/Ca treatment). The animals in the model group were pretreated with Ca ip at the doses of 25 mg x kg(-1) for rats and 150 mg x kg(-1) for mice, and then treated by LPS iv sixteen hours later, while in the control group were given normal saline (NS). Thrombosis in tails was observed at 24 h after LPS iv. Hematologic parameters were tested for all the animals from each species, and the blood concentration of TNFalpha and IL-6 at different time in SD and Wistar rats were measured.
Result:
LPS/Ca combinatory treatment could induce thrombosis animal model in all five animal species, and the thrombus could be clearly observed on the tails. All species had the similar change in hematologic parameters characterized as the significant decrease of white blood cells and platlets. Inflammatory factors TNFalpha and IL-6 could be largely induced in blood of both SD and Wistar rats at 2 h after LPS iv, but both inflammatory factors only transitorily exist in blood at the early stage of thrombosis model formation.
Conclusion:
LPS/Ca combinatory treatment can successfully induce thrombosis animal model in all tested animal species, and thus this model has extensive animal candidates. The secretion of a large amount of inflammatory factors plays a crucial role in the formation of thrombosis animal model.
