Figure 1From: Inhibition of antithrombin by hyaluronic acid may be involved in the pathogenesis of rheumatoid arthritisEffect of hyaluronic acid (HA) on antithrombin (AT). Various concentrations of HA, digested or not with hyaluronidase, were incubated with antithrombin in the presence of 5 mmol/l CaCl2 or FeCl3. Thrombin activity in the absence of both HA and antithrombin (blank) was considered as 1 and the activities of the other tests were normalized based on comparisons with blank. Values are expressed as mean ± standard deviation of data from triplicate experiments.Back to article page
