[The effects of heparin on intrauterine arteries of the human non-pregnant uterus: II. The analysis of the route of action].

Objective: Our purpose was to elucidate the mechanism of heparin action on smooth muscle of small intramyometrial arteries.

Material And Method: Material was obtained, contractility and calcium concentration were measured as previously described. Calcium influx to the vascular cells was also measured.

[The effects of heparin on intrauterine arteries of the human non-pregnant uterus: I. The action of clinically administered heparin].

Objective: Our purpose was to study the action of commercial unfractionated heparin on small human myometrial arteries, in vitro.

Material And Method: Pieces of myometrial arteries, about 1 mm. in external diameter, were obtained from premenopausal women undergoing hysterectomy.

[Hemostatic disturbances in women with unexplained fetal loss].

106 women was screened for a lupus anticoagulant. Activated partial thromboplastin time, tissue thromboplastin inhibition test and euglobulin lysis time was performed. Ten of 61 women (16%) with spontaneous multiple abortions, foetal death, intrauterine growth retardation (IUGR) and gestosis had one or two pathological results of tests while no one of the 41 women which had no pregnancy complication.

[Plasma fibrinolytic activity after gynecologic surgery].

Fibrinolytic activity and fibrinolytic potential has been estimated in women submitted of gynecologic operations. Results was referred to age, extension of the operation and character of illness. Elevation of fibrinolytic activity immediately after operation and fibrinolytic potential five days later have been stated.
