PATHOMORPHOLOGICAL CHANGES OF THE DIGESTIVE TRACT VESSELS AT COMPLICATED FORM OF HEMORRHAGIC FEVER WITH RENAL SYNDROME
The research aimed to estimate intensity of the morphological changes of the digestive tract vessels at complicated form of hemorrhagic fever with renal syndrome. Autopsy pieces of the stomach, duodenum and liver were fixed in 10% neutral formalin and after dehydration were embeded in paraffin by standard method. Mallory’s, van Gieson's, hematoxylin and eosin stains were used. Morphological changes were found in all layers of the vascular wall: endothelium was intensively desquamated, basic membrane was swollen and fragmented. Perivascular space was infiltrated by inflammatory cells. This vascular pathology was characterized as destructive-proliferative vasculitis.
