[Effect of dexamethasone on the ultrastructure of the myocardium in experimental hemorrhagic shock]

Authors studied the ultrastructure of the myocardium of rats treated with Dexamethasone in experimental haemorrhagic shock of 2.5 hours duration. The perfusion was performed on the Langendorff cannula. After preliminary treatment with Dexamethasone no characteristic morphological picture of the shock developed, but a marked accumulation of glycogen was observed. Authors believe that morphological pictures unambiguously evidence the anti-shock effect of Dexamethasone.
