EVALUATION OF ANTICOAGULANT EFFECT OF SULFATED POLYSACCHARIDE (SPS) FROM CODIUM DWARKENSE BORGESEN IN κ-CARRAGEENAN
Abstract:
Our aim of the present study was to evaluate the anticoagulant effect of sulfated polysaccharides (SPS) from Codium dwarkense Bergesen in ic-carrageenan induced hypercoagulable state in Wistar albino rats. 48 Wistar albino rats of either sex were randomly divided into 6 groups - disease control, active control, treatment lowmand high dose and preventive low and high dose. K-Carrageenan (3 mg/kg) single dose intravenously was given in rat tail vein at pre-decided time to produce hypercoagulable state. Baseline, 24, 48 and 72 hours duration blood samples were collected for PT, INR, aPTT, platelet count and fibrinogen level, FDP and D-Dimer measurements. At the end of experiment, animals were sacrificed for histopathology analysis of lung, liver and mesentery. Sulfated polysaccharide (SPS) significantly restored altered coagulation parameters (PT, INR, aPTI, platelet count and fibrinogen level) without affecting fibrinolytic parameters (FDP and D-Dimer). Administration of SPS both as a treatment and preventive therapy reduced the number of microthrombi along with less structural damage in histopathology of lung, liver and mesentery. Heparin served as active control and its administration significantly prolonged aPT' and restored PT. This study shows, anticoagulant activity of SPS extracted from Codium dwarkense Bergesen in Wistar albino rats.
