Dose Dependence of the Anticoagulant Effect of Intravenously Administered Cellulose Sulfate

Experiments on rabbits showed that increasing the dose of intravenously administered cellulose sulfate from wheat straw (dynamic viscosity 3.4 cP, sulfur content 14.1%) increased plasma clotting time in some coagulation tests and plasma anticoagulant activity. When cellulose sulfate was administered in the dose of 1 mg/kg, plasma clotting time in the presence of the anticoagulant (5 min after administration) was similar to 3-fold higher than after saline administration.
