RESUMO
<p><b>OBJECTIVE</b>To evaluate the effect of decoction for invigorating the kidney and improving blood circulation to thrombosis on rabbits blood stasis model.</p><p><b>METHOD</b>Thirty rabbits were randomly divided into normal group, model group, heavy dose group, slight dose group and xue shuan ning group. Tissue-type plasminogen activator (t-PA), plasminogen activator inhibitor (PAI), fibrinogen (Fbg) and D-dimer (DD) were investigated after those rabbits had been treated. One was selected randomly from each group to observe pathological changes.</p><p><b>RESULT</b>There was significant difference in t-PA, PAI, Fbg and DD between normal group and other groups (P < 0.01). Among groups of heavy dose, slight dose, xue shuan ning and model, the statistical differences were significant, as well as among groups of heavy dose, slight dose and xue shuan ning (P < 0.05). However, there was no statistical difference between heavy dose group and slight dose group (P > 0.05). The pathological changes in model group were most serious, and those in xue shuan ning were less serious. There were slight pathological change in heavy dose group and light dose group.</p><p><b>CONCLUSION</b>Models were made successfully. Heavy dose group and slight dose group have stronger effect on thrombosis than xue shuan ning group.</p>
