Effect of α lipoic acid amide on hexachlorobenzene porphyria
The aim of this work is to study the effect of thioctamide - the commercial form of a lipoic acid amide - on the porphyrinogenic action of hexachlorobenzene (HCB). For this purpose, porphyria was induced in rats by chronic HCB treatment, with or without simultaneous thioctamide administration. Two d...
