Abstract:
The ultrastructural changes of atrial myocardial cells during hemorrhagic shock and after autotransfusion with the shedded blood were observed in rats,which were divided into control,hemorrhagic shock and auspeto-transfusion groups.It was found that there was a marked increase of atrial specific granules in the atrial myocardial cells during hemorrhagic shock.Striking ultrastructural changes of atrial myocardial cells were noted after transfusion of the shedded blood.Reduction in the number of atrial specific granules,in addition to mitochondrial swelling,reduction of the cristae,focal emptying of mitochondria,myelin-like figure in mitochondrial matrix,expansion of sar-coplasmic reticulum,dilatation of Golgi complexes and perinuclear space,and dissociation of myocardial disk,were remarkable.The findings suggest that atrial myocardila cells participate in the patho-physiological changes of hemorrhagic shock and autotransfusion.
