Paraquat (gramoxone) poisoning in south-west Hungary, 1977-1984. Toxicological and histopathological aspects of group intoxication cases.
Fifty-six cases of paraquat poisoning were examined during the 8 years 1977-1984. The ratio of cases of accidental to intentional ingestion of the poison was 1:1; 23.2% of the total (13/56) survived several months or years. In 1983, 11 subjects accidentally drank 10-30 ml of gramoxone; eight of 11 died in 2 weeks. Toxicological investigations demonstrated rapid elimination of poison from the blood, as well as prolonged fixation of paraquat in the lung, kidney, liver, and spleen tissues. Histological examinations showed multiorgan failure from renal tubular necrosis and pulmonary hemorrhage with alveolar epithelial injury. Pulmonary proliferative changes were present in only two cases who survived 7 and 10 days and in which artificial ventilation was utilized.
