Groups of rats weighing 250-300 g were administered a single oral dose of heparin, high molecular weight heparin-DOCA, or low molecular weight heparin-DOCA. Blood samples (0.5 ml) were collected serially by heparin coated capillary mixed with 3.8% sodium citrate. Samples were collected prior to administration of heparin or heparin derivatives and for 10 hours thereafter at hourly intervals. Plasma was harvested by centrifugation and was frozen at below -20 °C. Plasma heparin activity in each sample was determined by APTT assays. The APTT bioassay was performed according to the procedure of Example 6. Plasma APTT units were determined from clotting time, which was
