Coagulant time (prothrombin time (PT), thrombin time (TT), activated partial thromboplastin time (APTT), and heparin bioactivity of PU and heparinized PU films.
| Samples | PT (s) | TT (s) | APTT (s) | Bioactivity (%) |
|---|---|---|---|---|
| Control | 12.4 ± 0.4 | 18.5 ± 0.5 | 35.7 ± 0.6 | |
| Blank PU | 12.9 ± 0.4 * | 20.7 ± 2.3 * | 40.8 ± 0.6 * | |
| PU-Hep-10 | 23.4 ± 1.1 %, & | 89 ± 2.9 %, & | 84.3 ± 1.3 %, & | 22.9 %, & |
| PU-Hep-6 | 29.1 ± 0.9 % | 104.7 ± 3.2 % | 102.8 ± 2.2 % | 28.8 % |
| PU-Hep-2 | 37.3 ± 1.5 & | 124.3 ± 3.5 & | 117.5 ± 4.4 & | 36.9 & |
(*) are significant differences (p < 0.05) compared to PU films tethering heparin; (%) are significant differences (p < 0.05) compared to PU-Hep-2; (&) are significant differences (p < 0.05) compared to PU-Hep-6.
