The aim of the present work is to shed light on the way of action of hexachlorobenzene (HCB) on hepatic ferrochelatase the mitochondrial enzyme which catalyzes the last step of haem biosynthetic pathway. 2.

In contrast, ferrochelatase activity was found to be unchanged 1 day after TCB.

Subsequently, an increase in delta-aminolaevulinate (AmLev) synthase and ferrochelatase was detected; AmLev dehydratase was the last to increase.

Braz J Med Biol Res. 2002 Nov;35(11):1273-83.

We evaluated the porphyrinogenic ability of ethanol (20% in drinking water) per se, its effect on the development of sporadic porphyria cutanea tarda induced by hexachlorobenzene in female Wistar rats (170-190 g, N = 8/group), and the relationship with hepatic damage.
Ethanol reduced the activities of uroporphyrinogen decarboxylase, delta-aminolevulinate dehydrase and ferrochelatase.

The present study was undertaken to explore the effect of the presence of hepatic tumors induced by diethylinitrosamine (DENA) on the metabolic heme pathway, and to assess whether these tumors can modify the response of rats to the porphyrinogenic drug hexachlorobenzene (HCB) and whether the above mentioned effects occur to a greater extent in females than males.
The results obtained showed that: a) Females were more susceptible to the hepatocarcinogenicity of DENA than males. b) Female normal and DENA treated rats were more susceptible than male rats to the porphyrinogenicity of HCB. c) The presence of hepatic DENA induced tumors could diminish basal hepatic ferrochelatase activity. d) Hepatic tumors could modify the response of animals to a porphyrinogenic drug such as HCB.

So it was studied, in liver: a) porphyrin content which was significantly increased at five months of HCB treatment, specially in males, and the pattern of accumulated porphyrins which was altered independent of the sex, b) haem pathway enzymes:delta aminolaevulinic acid synthase, ferrochelatase and porphyrinogen carboxylyase (PCL); among which only PCL appeared to be altered just at ten months of HCB feeding.
