In the course of 14 weeks exposure to mercury (7439976) compounds, including MetHg (a fluid seed dressing), mercuric-chloride (7487947), ethyl mercuric-chloride (107277) and phenyl-mercuric- chloride (100561), in doses corresponding to 5 percent of the median lethal dose three times a week, enhanced levels of activity of malate-dehydrogenase and glucose-phosphate isomerase in blood serum were observed. After 7 weeks of exposure about a four fold increase of malate-dehydrogenase (9001643) and two to three fold enhancement of glucose-phosphate isomerase activities were found relative to controls. After 14 weeks of exposure to MetHg or ethyl mercuric- chloride, organic mercury was found in the liver at concentrations of 28.8 and 4 micrograms per gram of tissue, respectively. Inorganic mercury was found in the livers of animals given any of the compounds.
