Effect of desferrioxamine on the development of hexachlorobenzene-induced porphyria
The present work deals with the effect of desferrioxamine (DP) on hexachlorobenzene (HCB)-induced porphyria in female rats with the purpose of further investigation of the role of iron in the development of this porphyria. The results obtained show that the repeated injection of DF (three times a we...
