Studies on Peripheral Circulation by "Ultrasonic Blood-Rheograph"

Studies on blood viscosity during extracorporeal circulation.

Blood viscosity was studied during extracorporeal circulation by means of a cone in cone viscometer. This rotational viscometer provides sixteen kinds of shear rate, ranging from 0.05 to 250.2 sec-1 • Merits and demerits of the equipment were described comparing with the capillary viscometer. In experimental study it was well demonstrated that the whole blood viscosity showed the shear rate dep...

Studies on the peripheral pulmonary circulation time in COPD.

Studies on the disturbances of the cerebral blood circulation.

The studies on the disturbances of cerebral blood circulation have been made by the writer and his coworkers since 1955.(1-9) In this work, new findings of the cerebral vascular architecture (both arteries and veins) were obtained with the methods of acrylic resin injection into the cerebral vessels.(3.7) From the view of the cerebral vascular architecture, a pathogenesis of cerebral hemorrhage...

Studies of Adult Peripheral Blood

A B S T R A C T By using a methylcellulose clonal assay, we cultured peripheral blood erythropoietic precursors from a patient with sickle cell anemia, a patient with sickle cell hemoglobin C disease, and a normal volunteer. We then analyzed the synthetic rates ofadult and fetal hemoglobins (Hb) in individual erythropoietic bursts. Hb were labeled with '4C-amino acids in culture, separated by s...

Studies of peripheral circulation during sickle-cell crisis.

IT IS WELL recognized that patients with sickle-cell disease may have a low saturation and tension of arterial blood oxygen. Although arterial anioxemia was first observed in 1942, its exact mechanism is still unknown.1 It has been shown that the hemoglobin dissociation curve of these patients is shifted to the right, probably because of a decrease in erythrocyte pH.2, 3 Therefore, a norimal le...
