The aim of this study was to evaluate together the main hemorheologic parameters and one of the transmembrane ion transport systems in erythrocytes of subjects with normal and elevated blood pressure. Three sex-, age-, and weight-matched groups consisting of 15 normotensive subjects (NT) with no parental hypertension, 15 patients with essential hypertension (EH) at stage 1-II WHO, and eight patients with secondary hypertension (Sec.H), respectively, were studied. Red blood cell Na+-Li+ countertransport (CTT), blood viscosity (eta B) at shear rates of 230 X S-1, 115 X S-1, and 46 S-1 and plasma viscosity (eta P) at shear rate of 46 X S-1 were measured. Plasma proteins and fibrinogen were also evaluated. CTT was higher in EH than in NT (P less than 0.01), while no significant difference was found between NT and Sec. H patients. eta B at 115 X S-1 and 46 X S-1 was higher in EH, but not in Sec. H, than in NT patients (P less than 0.05). No difference in eta P, plasma proteins and fibrin...

Pregnancy is characterized by plasmatic variations of coagulative factors' concentration and by different haemostatic-fibrinolytic balance. At present it is possible, with EIA methods, to measure fibrinogen (FgDP) and fibrin (FbDP) degradation products with precision and accuracy, as direct indexes of fibrinolysis and the thrombin-antithrombin III complex (TAT) as indirect index of thrombophilia. We have considered the course of those indexes in 61 pregnant women within the tenth week of gestation, before and after voluntary pregnancy interruption (VPI) resulted without complications. The results don't show any peculiar variation of the examined parameters between the pregnant women before VPI and a control group. Comparing the basal data with those obtained three hours after VPI, all indexes are increased, particularly FbDP. After 24 hours the concentration of FgDP, FbDP and TDP decreased in comparison with the three hours control drawing, nevertheless staying higher than the values obtained in the basal drawing. The evolution of FDP and of TAT, in our study, points out that, in the first weeks of pregnancy, the haemostatic-fibrinolytic balance does not differ significantly from the physiological balance. Three hours after VPI fibrinolytic mechanisms prevail as regards the fibrinogenolytic ones. TAT increases after 3 hours and returns to the rules after 24 hours, proposing itself as an indirect index of thrombinic activation and as a direct index of antithrombinic activity.
