Activity of coagulation and fibrinolytic system components in the vein thrombus.

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 activators, plasmin (plasminogen) and antiplasmins of the vein thrombus homogenate was determined using coagulative, fibrinolytic and caseinolytic tests.

Thyroid volume and hormone response in the early kidney transplants.

Background: Thyroid hormones could affect renal function, and conversely renal function disturbances may affect thyroid function. Disturbances of the thyroid hormone concentration are often connected with thyroid gland enlargement. The aim of study was to estimate the function and morphology of the thyroid and kidney graft after kidney transplantation.

Activity of enzymes with different subcellular localization in the blood plasma of patients with aortic aneurysm.

Background: The wall of an abdominal aorta aneurysm shows increased activity of metalloproteinases, aspartyl cathepsins and cystein cathepsins, and decreased activity of inhibitors of these enzymes, as compared to the wall of a normal aorta. Parietal thrombi of the aneurysm also show marked proteolytic activity. The aim of our study was to determine the activity of secretory enzymes, membrane enzymes, cytosol enzymes, mitochondrial enzymes and lysosomal enzymes in the blood plasma of patients with abdominal aortic aneurysm.

[Techniques for creating hemodialysis fistulas].

Hemodialysis is the primary method of renal replacement therapy. To conduct hemodialysis therapy, an effective vascular access is necessary. The authors describe basic types of surgically created accesses for hemodialysis and their complications.

Haemoglobin of varicose vein, varicose vein with thrombophlebitis and in parietal thrombus of varicose vein.

Saphenous veins were taken for examination: unchanged, varicose with thrombophlebitis and varicose thrombus. The contents of haemoglobin and protein were determined in the homogenate of that material. Only small quantities of haemoglobin were found in walls of unchanged veins.

Assessment of connective tissue fibres in walls of allogenic arterial grafts preserved by the method of cold ischemia--a preliminary report.

The aim of the study was to evaluate microscopic changes in the wall structures of allogenic arterial grafts, preserved by the method of cold ischemia in relation to the storage period and to test the possibility of the storage period prolongation by allograft freezing at -70 degrees C. The middle layer ultrastructure is well preserved till 30 days from allograft harvesting, however, allograft freezing results in total destruction of elastic and collagen fibres in the arterial wall. An application of allogenic arterial grafts, preserved by the method of cold ischemia till 30 days from their harvesting, seems an efficient therapeutic method in the treatment of patients with synthetic vascular graft infection.
