From: Bovine and porcine heparins: different drugs with similar effects on human haemodialysis
The anticoagulant activities of the pharmaceutical preparations of bovine (in blue) and porcine (in red) heparins and of the 5thInternational Standard for Unfractionated Heparin (in black) were checked based on the aPTT assays. (A) The results are expressed as IU of the anticoagulant activity reported by the manufacturer vs. ratio of the coagulation time in the presence (T) and in the absence of heparin (T0) as mean ± SD. * indicates p < 0.001 for bovine vs. porcine heparin. (B) The results are expressed as hexuronic acid content of the pharmaceutical preparations vs. ratio of the coagulation time in the presence (T) and in the absence of heparin (T0) as mean ± SD.
