Apoptosis in the cells of parenchymatous organs in subacute sodium nitrate poisoning
Subacute intoxication was induced by the oral administration of sodium nitrate 200 mg/kg during 150 days to Wistar rats. After the time had been up severe damaging were found in liver, kidney, heart and thymic tissues. In the liver cells the DNA fragmentation in "scale" manner was found, but not in kidney and heart cells. Simultaneously, the Ca2+, Mg(2+)-depended endonucleases activity were increased in the liver nuclei extracts under intoxication. It was suggested that increasing of apoptosis in liver is the universal reaction to toxins.
