Abstract
The effects of diabetes mellitus and myocardial infarction on the erythrocyte sedimentation profiles under gravitational field are determined by the transmission of He-Ne laser light through the blood sample contained in a glass chamber, and are compared with that of normal sample. It has been observed that the sedimentation profiles at various points in the blood column depend on the clinical status of blood. In myocardial infarction the erythrocytes tend to settle faster than that of diabetes mellitus at all time intervals, which in turn sediment faster than that of normal blood. The aggregation index, (as obtained by the ratio of the transmittod intensity for normal to that of diseased blood) is higher in myocardial infarction compared to that of diabetes mellitus at all time intervals.
