![]() ![]() Journal: Clinical Hemorheology and Microcirculation, vol. Keywords: Antigens, Blood Groups, Blood Viscosity, Hypertension From: Reference Module in Biomedical Sciences, 2014. There was no significant difference in hematocrit and platelet aggregation. Blood viscosity is a further factor that affects PVR, for example when polycythemia increases PVR. When whole blood viscosity, plasma viscosity, red cell rigidity, fibrinogen and triglyceride parameters were compared with normal controls, they were found to be significantly elevated. This change in the whole blood viscosity among different blood groups could be due to difference in the charge density of different blood groups and/or particular blood group is more susceptible for change in the blood viscosity. It shows that red blood cell is one of the major contributing factor for change in whole blood viscosity. There was no significant difference in the plasma viscosity among different blood group. We have found that in case of blood group “O” increase in the whole blood viscosity was maximum while in blood group “B” it was minimum. ![]() Plasma viscosity, red cell rigidity, platelet aggregation, erythrocyte sedimentation ra te, hematocrit, fibrinogen, and serum triglyceride were also studied. Whole blood viscosity was measured at 8 different shear rates and was categorized as per individual's blood group. | Jaiswal, V.S.Īffiliations: School of Biomedical Engineering, Indian Institute of Technology, Powai, Bombay 400 076, IndiaĪbstract: Hemorheological and biochemical investigations were performed in 274 patients with hypertension. ![]()
