Neutralization of streptokinase by an unsuspected high titer of antistreptokinase antibody prevented activation of the fibrinolytic system and induction of a lytic state in a 62 year old man with an acute inferior myocardial infarction. There was no decrease in serum fibrinogen, minimal decrease in serum plasminogen and only a small increase in serum fibrin degradation products after intravenou...

The purpose of this study was to determine whether streptokinase (1) exacerbates intramyocardial hemorrhage during coronary reperfusion, (2) has any intrinsic effect on myocardial infarct size other than its ability to lyse proximal thrombi in coronary arteries, and (3) can abolish the no-reflow phenomenon. Anesthetized open-chest dogs underwent coronary occlusion for 3 hr followed by 3 hr of r...

It has been shown that the activation of bovine plasminogen by streptokinase plus a trace amount of human globulin involves a two-stage activation process (1, 2). Ablondi and Hagan (3) proposed that the proactivator of bovine plasminogen was identical with human plasminogen, which became activator by forming complexes with streptokinase. Kline and Fishman (4) using a lysine methyl ester assay d...

Tissue type plasminogen activator (t-PA) is an effective thrombolytic agent in experimental animals. The duration of the thrombolytic effect of infused t-PA is unknown. We compared the duration of the thrombolytic effect of t-PA with streptokinase by measuring the lysis of 125I-fibrin-labeled thrombi in rabbit jugular veins at different times after a bolus injection of the fibrinolytic agents. ...

The role of early effective drainage in loculated tuberculous (TB) pleurisy treatment remains unclear. Consecutive patients with TB pleurisy subjected to anti-TB treatment and pigtail drainage (n = 64) were divided into three groups: 1) patients with free-flowing effusions irrigated with saline (free-flowing group; n = 20); 2) patients with loculated effusions irrigated with streptokinase (stre...

Plasma concentrations of immunoreactive atrial natriuretic peptide (mean (SEM] were measured in 135 patients admitted to two coronary care units with myocardial infarction, ischaemic chest pain, or non-ischaemic chest pain. Concentrations were significantly higher in patients with acute myocardial infarction not treated with systemic thrombolysis (60.4 (14.3) pg/ml) than in patients with non-is...

BACKGROUND Existence of bacterial host-cell DNA contamination in biopharmaceutical products is a potential risk factor for patients receiving these drugs. Hence, the quantity of contamination must be controlled under the regulatory standards. Although different methods such as hybridization assays have been employed to determine DNA impurities, these methods are labor intensive and rather expen...

Vasculitis developed in six of 253 patients treated with intravenous anisoylated plasminogen streptokinase activator complex (APSAC) after acute myocardial infarction. All patients recovered spontaneously with no evidence of renal impairment and no long term sequelae. Although leucocytoclastic vasculitis and serum sickness have been reported after streptokinase treatment, such allergic reaction...

From September 1962 to May 1972 145 patients with acute or subacute deep vein thrombosis confirmed by phlebography were treated with streptokinase. During the same period 42 patients considered unfit for thrombolytic therapy were treated with herapin and oral anticoagulants. The results, assessed by repeat phlebography, in 93 of the patients treated with streptokinase were compared with those i...
