Thrombolytic therapy with high doses of streptokinase (SK), which are required due to its rapid clearance from the bloodstream, is accompanied by side effects. In this work, the SK was incorporated into water-soluble polyethylene glycol (PEG) microcapsules with the double emulsification method in order to increase its lifetime in bloodstream and decrease(More)
The comparative in vitro study of the kinetics of various reactions involved in the process of thrombolysis initiated by streptokinase (SK) and staphylokinase (STA) has been carried out. It has been shown that upon the interaction of plasminogen (Pg) with SK or STA in equimolar quantities, the formation rate and the specific esterase activity of the complex(More)
Plasma level of IgG autoantibodies to plasminogen was measured by ELISA in patients with benign prostatic hyperplasia (n=25), prostatic cancer (n=17), lung cancer (n=15), and healthy volunteers (n=44). High levels of IgG to plasminogen were found in 2 (12%) of 17 healthy women, in 1 (3.6%) of 27 specimens in a healthy man, in 17 (68%) of 25 specimens in(More)
Covalent SK-PEG2 and SK-PEG5 conjugates with various degrees of modification of the protein amino groups were obtained by variation of the duration of streptokinase (SK) incubation with activated polyethylene glycol (M 2 and 5 kDa, PEG2 and PEG5); their properties were studied in comparison with the properties of unmodified SK in vitro. SK-PEG2 and SK-PEG5(More)
