Plasma fibrinolytic activity and plasma inhibitory activity against urokinase and tissue activator were measured in primigravidae with moderate or severe pre-eclampsia and in gestation-matched primigravidae with uncomplicated pregnancy. The mean levels of fibrinolytic activity and inhibitory activity against urokinase and tissue activator did not differ significantly between the pre-eclampsia a...

PURPOSE Behaviour of the vein thrombus is determined by the activity ratio of coagulation factors to factors of fibrinolytic system. The aim of the study is to evaluate activity of some coagulation and fibrinolytic factors in the vein thrombus. MATERIAL AND METHODS The activity of platelets aggregating factors, tissue factor, thrombin, antithrombins, antiheparin factors, plasminogen activator...

Bacillus sp. can biosynthesize fibrinolytic enzymes. Culture conditions and nutrient sources are important factors affecting microbial growth production of the Fibrinolytic enzyme. Therefore, we investigated culture strain ES4, such as temperature, pH, C source (glucose, sucrose, glycerol, maltose), N (yeast extract, meat content, peptone, tryptone), metal ions (Ca 2+ , Mg Mn Zn K + Fe Cu ), ti...

PURPOSE The purpose of this study was to analyze the effects of estrogen deficiency and hormone replacement therapy (HRT) on fibrinolytic activity in a rat mode of surgically-induced menopause. METHODS Twelve-week-old, sexually mature female Sprague-Dawley rats, each weighing 200-250 g, were randomly divided into four groups: (1) sham-operated group, (2) ovariectomy group, (3) ovariectomy gro...

By A. E. D R AND D. Ku ui A GROWING INTEREST in fibrinolytic agents has given rise to a variety of methods for assessing the activity of such agents in vitro. The fibrin plate assay1 is a useful technic employing the natural substrate. Other methods,2 using formed fibrin clots, have also been devised, as well as technics employing other substrates such as casein. The purpose of this study was t...

Diurnal patterns of plasma euglobulin fibrinolytic activity, estimated by the fibrin plate method, were determined in groups of young normal and older normal subjects, in subjects with type IV hyperlipoproteinemia, and in subjects with coronary artery disease who had normal lipid profiles. The marked diumal increases in fibrinolytic activity observed in the young normal subjects were significan...

Antithrombotic and fibrinolytic activity of natto was evaluated on platelet aggregation in vitro and in vivo. Natto showed inhibitory effects on platelet aggregation induced by adenosine 5'diphosphate (ADP) and collagen. Orally administered natto also showed fibrinolytic activity in hypercholesterolemia rats. Normal levels of natto, when administered for four weeks, shortened euglobulin clot ly...

Fibrinolytic enzymes have nowadays found important place in the medical field. Only few studies had reported the fibrinolytic enzyme production from actinomycetes. So the microbial fibrinolytic enzymes, especially those from actinomycetes, have the potential to be developed as drugs to prevent cardiovascular diseases. Actinomycetes were producing strong enzymes with no side effects, non pathoge...

Exhaustive bicycle ergometric exercise in 20 untrained male and female medical students in the age group of 18-25 yrs resulted in significant changes in clotting and prothrombin time, platelet adhesiveness and fibrinolytic activity. Clotting and Prothrombin time were reduced while platelet adhesiveness and fibrinolytic activity were increased in both the sexes.

The effects of phenformin and ethyloestrenol and phenformin and stanozolol on the clinical state, plasma fibrinolytic activity, and fibrinogen-fibrin-related antigen (F.R.-antigen) were compared with placebo in 13 patients with cutaneous vasculitis. Eight patients showed considerable clinical improvement when taking phenformin and an anabolic steroid; an impaired fibrinolytic activity before tr...
