Some split exact sequences in the cohomology of groups

Abstract The efficacy and safety of two methods of heparin administration was investigated; 100 patients with calf vein thrombosis were randomly allocated to receive either subcutaneous (SC) or intravenous (IV) heparin for seven days. Venography was performed in each patient to confirm the exact size and site of thrombus and was repeated at the end of heparin treatment. IV heparin was administered using a constant infusion pump. The dose of heparin to be administered was determined by daily estimation of KCCT. In SC group, thrombi increased in size in 2%, remained unchanged in 50% and decreased in 48%. In the IV group, they increased in size in 20%, were unchanged in 62% and decreased in 18%. The difference in decreases in size was significant (p
