Charts of 1006 consecutive outpatients were reviewed to ascertain the cause of extreme elevation of the erythrocyte sedimentation rate (ESR) (greater than or equal to 100 mm/h) and the sensitivity of marked ESR elevation in patients with disorders commonly reported to cause ESR elevation. Prevalence of ESRs of 100 mm/h or more was 4.2%. Infection was the most common cause (33%), with malignant ...

The sedimentation rate of the red blood cells was determined of 74 epidemic dropsy patients and of 8 persons in whom symptoms resembling those of epidemic dropsy were produced after taking food cooked in mustard oil incriminated in natural outbreaks of the disease or in mustard oil to which known quantities of argemone oil had been added (Chopra et al., 1939). The cell volume and the haemoglobi...

as a routine screening test. Borchgrevink, Heist0, and Reimers Reksten (1965) found 41 (2 per cent.) of 2,205 Norwegian male blood donors with an ESR over 20 mm./hr; nineteen of these showed a persistent elevation. The ESR has not usually been included in screening programmes (Jungner, 1966; Collen, 1966), but we have found it of great value and therefore present our experience with 2,000 men. ...

In recognition of the need for a standardization of the measurement of the erythrocyte sedimentation rate (ESR), the International Council for Standardization in Haematology makes the following recommendations: (i) The reference method for measurement of the ESR should be based on the Westergren method, which is a specific test for the ESR, with modifications, (ii) The reference method for meas...

We have investigated DNA superstructure in a wide range of nuclei of higher cells by gently lysing cells to release structures that resemble nuclei but are depleted of nuclear proteins. The sedimentation properties of these structures, which we call nucleoids, have been examined in sucrose gradients containing the intercalating agent, ethidium. The sedimentation rate of nucleoids derived from t...
