[Histomorphometry of megakaryocytes in bone marrow during acute hemorrhagic shock in rats].

Quantitation and morphometric parameters of bone marrow MK in rats during acute haemorrhagic shock were analysed. The results were compared with group of normal rats and rats after surgical manipulation. In examining animals statistical significant differences were observed in localization, size, form factor, N/C ratio, forming cluster forms and phenomena of emperipolesis. These disturbances of MK were often observed in rats after surgical manipulation. The results indicate that the changes of MK have just observed after 60 min. from indication of haemorrhagic shock.
