title: [Contents of prostaglandins F2alpha, I2 (prostacyclin) and thromboxane A2 in the dog liver during development of hemorrhagic shock].
abstract: Contents of prostaglandins (PGs) F2 alpha, I2 and thromboxane (TH) A2 in the liver of 6 dogs has been studied in dynamics of hemorrhagic shock development. The results show that acute haemorrhage (31.9 +/- 1.6 ml/kg) stimulates the synthesis and release of all the eicosanoids studied. Nevertheless, in the progression of shock a significant difference was noticed between the high TXA2 and PGF2 alpha rates and comparatively lower rise of PGI2 production. The late stage of shock (201 +/- 44 minutes after haemorrhage) was characterized by a further rise in TXA2 and PGF2 alpha rates with simultaneous lowering of PGI2 as a result of vascular endothelium affection which is the main source for prostacyclin synthesis. In view of the antagonism of PGI2 to TXA2 and PGF2 alpha and its cytoprotective effects, the results of present investigation give the experimental background for using prostacyclin or its synthetic analogues in a complex therapy of acute liver failure in clinic.
