examination of all patients, has been outstanding in the minds of cancer specialists and public health authorities for years . Bolen' has advocated the gross and microscopic (low power) morphology of' dried drops of blood as sufficiently diagnostic to fill this need in many instances. Bolen employs the technic of Goldbergera as a rapid bedside test for measuring the blood sedimentation rate . G...

In a previous publication it was pointed out that definite relationships existed between the growth curve of a 100 per cent transplantable methylcholanthrene-induced hamster sarcoma and several blood cell factors (1~). As the tumor grew in the hamster cheek pouch, characteristic alterations were noted in the levels of hemoglobin, red and white blood cells, differential white blood cell counts, ...

The erythrocyte sedimentation rate (ESR) test has been used for over a century. The Westergren method is routinely used in a variety of clinics. However, the mechanism of erythrocyte sedimentation remains unclear, and the 60 min required for the test seems excessive. We investigated the effects of cell aggregation during blood sedimentation and electrical conductivity at different hematocrits. ...

Venous blood is necessary for the estimation of the erythrocyte sedimentation rate (E.S.R.) by the methods of Westergren (1921) and Wintrobe and Landsberg (1935), but venepuncture may occasionally prove difficult or impossible, owing to such factors as inadequate veins, obesity, and flexion deformities. A search was therefore undertaken for a reliable method of estimating the E.S.R. using capil...

The viscosity of the plasma was studied briefly by Fahraeus in his original investigations (1921) into the blood sedimentation rate. In 1940 further studies were made by T'Ang and Wang, who concluded that it gave a more accurate picture of the activity of disease processes than the erythrocyte sedimentation rate. The plasma viscosity technique was independently developed by Whittington and his ...
