EFFECT OF CHRONIC LEAD POISONING ON ERYTHROCYTE PROTOPORPHYRIN IN RATS

Research has shown that exposure to lead may have adverse effects at different blood lead concentrations. Lead inhibits at least two enzymes that are essential for the formation of heme, and because of the interaction of lead with these enzymes, no iron is inserted into protoporphyrin. Therefore the concentration of protoporphyrin increases in erythrocytes. The concentration of lead was mea...

Chronic beryllium poisoning.

In 1933 Weber and Engelhardt reported the first case of acute pneumonitis due to beryllium poisoning. Other instances of the acute reaction to beryllium salts were described by Van Ordstrand, Hughes, DeNardi, and Carmody (1945). Hardy and Tabershaw (1946) gave details of the chronic or delayed form of the disease, and DeNardi, Van Ordstrand, Curtis, and Zielinski (1953) published a review of 46...

Chronic organophosphate poisoning.

Prolonged exposure to organophosphates in low concentrations caused diarrhoea in 38 students, lecturers and other personnel at an agricultural college. The symptoms of those affected, plasma pseudocholinesterase levels, topography of the orchards and vegetable gardens, the various insecticides and quantities used, and the exposure due to prevailing winds have been studied. We conclude that safe...
