title: [The role and morphology of thrombocyte concentrates prepared from a buffy coat].
abstract: The results of quantification and investigation of thrombocyte morphology in 112 concentrated thrombocyte units, prepared from buffy coat of the whole blood taken from the unchosen donors are shown. Immediately after the preparation of units the thrombocyte count was 66.99 +/- 7.04 x 10 cells (contribution of procedure 65.05%), the number of residual leukocytes 70.2 +/- 17.91 x 10 cells and the value of morphological thrombocyte score was 364 +/- 32.1. During the first day of storage on the temperature of 20 +/- 2 degrees C, along with the constant shaking of units the significant decrease of number of morphological score of thrombocyte (p < 0.05) was stated. Beside the mentioned side effects, the units of concentrated thrombocytes prepared in this procedure showed to be therapeutically effective after the storage of 5 days. In contribution to this spoke electronic-microscopic investigations that showed the presence of degenerative changes of thrombocytes during the fourth day of storage. Further improvement of procedure is necessary due to the prolonged preservation of the concentrated thrombocyte units quality.
