| pubmed-article:6229901 | pubmed:abstractText | Mercuric chloride (HgCl2) induces in Brown Norway (BN) rats an autoimmune disease characterized by a biphasic glomerulonephritis (GN). A transient nephrotic syndrome occurs during the third and fourth weeks after the first HgCl2 injection. Related to nephrotic syndrome, an hypercoagulable state develops with decreased factor XII and anti-thrombin III (AT III) levels and increased factor V activity and fibrinogen concentration. Moreover, during the same period, most of the rats were found thrombocytopenic. The presence of soluble fibrin monomer complexes and of fibrin degradation products (FDP) in the plasma of these rats associated with fibrin thrombi in glomerular capillary lumen proved the occurrence of disseminated intravascular coagulation (DIC). DIC was responsible for the death of several rats but most of these survived and clotting abnormalities were no longer found. Numerous factors can explain the occurrence of DIC in this model: anti glomerular basement membrane antibodies, circulating immune complexes, complement activation and/or glomerular endothelial cell detachment. The HgCl2 induced autoimmune disease appears as a good experimental model to study the relation between coagulation process and glomerulonephritis. | lld:pubmed |
