[Changes in the intraorganic vessels of the liver in acute experimental peritonitis]. 1988

G S Ivanova, and V I Glumov, and A K Kranchev, and V L Bazhenov

Structural pathology and hemodynamics in the livers of 110 white rats were studied histologically, electron microscopically and histoautoradiographically during 5 days since the onset of acute experimental peritonitis. This was accompanied with distinct structural and functional derangement of histohematic barrier along with hepatic hemodynamic disturbances dependent in severity on both fecal suspension quantity and AEP course and stage. Pathologic and compensatory-adaptive reactions profile was established for the animals intrahepatic circulation. Polymorphism of the vascular affections underlies the emergence of the two morphogenetic mechanisms responsible for impairment of hepatic parenchyma: 1) a direct action of toxic substances on hepatocytic cellular membranes, 2) disordered circulatory-hypoxic effect based on pronounced DIC-syndrome and thrombosis. The former mechanism gives rise to disseminated necrosis of hepatocytes, while the latter entails the onset of intralobular necrotic foci, typical for the reactive and toxic stages of acute peritonitis, respectively.

D008099 Liver A large lobed glandular organ in the abdomen of vertebrates that is responsible for detoxification, metabolism, synthesis and storage of various substances. Livers
D008297 Male Males
D008854 Microscopy, Electron Microscopy using an electron beam, instead of light, to visualize the sample, thereby allowing much greater magnification. The interactions of ELECTRONS with specimens are used to provide information about the fine structure of that specimen. In TRANSMISSION ELECTRON MICROSCOPY the reactions of the electrons that are transmitted through the specimen are imaged. In SCANNING ELECTRON MICROSCOPY an electron beam falls at a non-normal angle on the specimen and the image is derived from the reactions occurring above the plane of the specimen. Electron Microscopy
D009336 Necrosis The death of cells in an organ or tissue due to disease, injury or failure of the blood supply.
D010538 Peritonitis INFLAMMATION of the PERITONEUM lining the ABDOMINAL CAVITY as the result of infectious, autoimmune, or chemical processes. Primary peritonitis is due to infection of the PERITONEAL CAVITY via hematogenous or lymphatic spread and without intra-abdominal source. Secondary peritonitis arises from the ABDOMINAL CAVITY itself through RUPTURE or ABSCESS of intra-abdominal organs.

D004211 Disseminated Intravascular Coagulation A disorder characterized by procoagulant substances entering the general circulation causing a systemic thrombotic process. The activation of the clotting mechanism may arise from any of a number of disorders. A majority of the patients manifest skin lesions, sometimes leading to PURPURA FULMINANS.
