Effects of hexachlorobenzene and iron loading on rat liver mitochondria.

The effects of hexachlorobenzene treatment and simultaneous iron-overload on the iron and porphyrin content of rat liver and rat liver mitochondria have been examined. In order to assess damages to the mitochondrial membrane occurring with these treatments, the content of malondialdehyde and selected functional properties of mitochondria were compared with those from control animals. Prolonged intake of hexachlorobenzene (8 weeks) resulted in a strikingly increased level of porphyrins together with a moderate increase in iron concentration.
