The recently reported heparin fractionation method for measuring fibrinolytic activity in plasma (Green, 1959; Green and Thomson, 1962) has been used to re-examine the effect of certain physiological stimuli on fibrinolytic activity in man. In addition to providing further data on factors influencing natural fibrinolytic activity such a study afforded a means of assessing the value and sensitiv...

Fibrinolytic activity of colic venous and arterial blood has been studied at laparotomy in 18 patients with ulcerative colitis or Crohn's colitis and compared with that of 17 patients with colonic carcinoma or diverticulosis. Using the dilute blood clot lysis time technique, no difference was detected between the fibrinolytic activity in colic venous blood from the two groups. When the clinical...

SYNOPSIS The observation by Todd (1964) of a diffuse fibrinolytic activity related to the human endometrium in its secretory stage initiated a reinvestigation of the development of fibrinolytic activity in the uterus and vagina of the rat using the histochemical fibrin slide technique. In addition to the plasminogen activator known to be related to uterine vessels, in the rat in particular to m...
