Study Of The Effect Of Polysaccharides On Hemostasis

The effect of sulfated polysaccharides on the hemostatic system in conditions in vitro. Platelet-rich plasma was obtained by centrifugation at 200 g for 10 minutes. The remaining citrate blood was further centrifuged at 1500 g for 10 min to obtain platelet-poor plasma. The antithrombin activity of the compounds was evaluated in vitro by their effect on the recalcification time, thrombin, and prothrombin time of human blood plasma stabilized with a 3.8% sodium citrate solution in the ratio of 9:1. In studies conducted on the blood plasma of rats, it was found that the studied compounds, to varying degrees, lengthen the APTT, APTT, prothrombin time. At the same time, anticoagulant activity was established to block one of the factors II, V, X. Polysaccharide exhibit a combined anticoagulant effect in the body, due to which they are classified as anticoagulant and antithrombin agents.
