[Comparison of the number of dense bodies in blood platelets in patients with myocardial infarction].
Dense bodies present in blood platelets contain also serotonin, which together with other factors stimulates vasoconstriction. This paper presents an investigation of possible differences in the number of dense bodies in platelets of patient R.T., affected by two myocardial infarctions resulted in death, with the number of dense bodies in platelets of patient L.T., affected by the same type of myocardial infarct, however, without complications. Dense bodies were labelled with mepacrin and viewed and counted under the fluorescence microscope. Score for each type of platelet (containing 1-6 dense bodies) as well as a total score for each of 3 blood samples collected during acute phase of the infarct and then after 5 and 10 consecutive days were calculated. Increased number of dense bodies (6 per platelet) was seen in patient R.T. Also the total score was the highest. For comparison total score was calculated in an healthy person.
