| Popis: | We have observed the symptoms of systemic inflammatory response syndrome (SIRS) in male rats intoxicated by carbon tetrachloride (CCl4). Severe hypothermia, tachypnoea and increase in the heart beat min were diagnosed. These symptoms developed in the first hour of intoxication. The hepatic dysfunction was characterized by elevated bilirubin levels. In the sera we have measured increases in the activity of secretable (group II) phospholipase A2 sPLA2 (2,8x) and 6-ketoprostaglandin F1α (KPGF) (1,44x). Supposedly the free radicals derived from CCl4—mainly trichloromethyl—could induce the prompt reaction of SIRS and the release of sPLA2 as well as the formation of KPGF. Our findings show that in the early phase of CCl4 intoxication the symptoms of SIRS can be related to elevation of sPLA2 and the products of cyclooxygenase II. |
