Values for hemoglobin, erythrocytes, volume of packed cells, leucocytes, and their distribution, and red blood cell diameter are presented as determined on a group of 114 hamsters of both sexes and of various ages.

Packed erythrocytes are ideally suited as a model system for the study of water diffusion in biological tissue, because cell size, membrane permeability, and extracellular volume fraction can be varied independently. We used a pulsed-field-gradient spin echo NMR technique to measure the time-dependent diffusion coefficient D(t) in packed erythrocytes. The long-time diffusion constant, D(eff), d...

Hematologic parameters were studied in giant Canada geese (Branta canadensis maxima), mallard ducks (Anas platyrhynchos platyrhynchos) and various species of diving ducks at seasinal intervals throughout the year. Highest values for packed cell volume, hemoglobin content and erythrocyte counts were found in the winter and pre-nesting periods. Mean corpuscular volume and mean corpuscular hemoglo...

Lacunar (small deep cerebral infarcts) infarction is described in association with raised packed cell volumes. Two patients had polycythaemia vera, one stress polycythaemia. They presented with transient ischaemic episodes and were shown by computed tomography to have lacunes deep in the basal ganglia and internal capsule. Such lesions may be caused by small vessel occlusions related to increas...

BACKGROUND Febrile convulsion and sickle cell disease are common in tropical countries and both are associated with significant morbidity and mortality. Worldwide, Nigeria has the highest prevalence of sickle cell disease. However, there is a dearth of knowledge on the haemoglobin electrophoresis in patients with febrile convulsions. METHODS This was a hospital based, descriptive, cross-secti...

Objectives The aim of this study was to examine whether associations between disease severity and packed cell volume exist in dogs with myxomatous mitral valve disease. Materials Methods Data were selected from 289 that had been examined at a research clinic (2004–2017) on multiple occasions (n=1465). American College Veterinary Internal Medicine stage echocardiographic measurements entered sep...
