Effect of Lead on Globin Synthesis in Vitro

A defect in heme synthesis is well documented to occur in lead intoxication. Globin synthesis and the alpha/beta globin chain synthesis ratio have been shown to be disturbed in lead poisoning. To elucidate further the nature of the inhibitory effect of lead on hemoglobin synthesis, reticulocyte-rich peripheral blood samples have been incubated with lead at concentrations of 10(-6), 10(-5), and 10(-4) M, equivalent to 20, 200, and 2,000 mug/dl …
