Abstract

PURPOSES: Assessment of normal haematological values in the rabbit using a semi-automatic analyser. Evaluation of new haemostatic parameters necessary for experimental models in thrombosis and haemostasis. MATERIAL AND METHODS: 20 New Zealand male rabbits of 2-2.5 kg were anaesthetized and blood was collected from the jugular vein. The following haematological determinations were carried out using a semi-automatic analyser: red blood cells count, haemoglobin, haematocrit, indexes, white blood cells count, platelet count and mean platelet volume. The parameters used to assess the physiological haemostasis in rabbit were: bleeding time, fibrinogen, prothrombin time, activated partial thromboplastin time, thrombin time; and others not yet determined in the rabbit: antithrombin III, thrombin-antithrombin complexes and F1+2 fragments to measure the basal thrombin-formation activity, and fibrin D-dimer and fibrinogen degradation products for fibrinolysis activity. RESULTS: The haematological results obtained were similar than with other techniques, but with no stress influence. Normal values for haemostatic parameters studied are shown, including the parameters for the determination of physiological thrombin-formation and fibrinolysis activity. F1+2 fragments and fibrinogen degradation products could not be evaluated. CONCLUSIONS: The haematological results obtained were completely normal. All the haemostatic parameters studied were found useful to determine the physiological activity of coagulation and fibrinolysis in the rabbit, and specially for experimental models of hypercoagulability and hyperfibrinolisys states.
