1, the parent compound alone is the ultimate toxic agent responsible for damage to extrahepatic tissue in mechanism ‘A’. The extrahepatic organ in which toxicity develops may depend upon selective exposure, preferential uptake or preferential concentration of the toxic agent in the target tissue, or upon the presence of specific receptors or other highly susceptible sites of action. Alternatively, there may be little selectivity of target organ; the toxic agent may affect the liver as well as many extrahepatic sites.
DNA was isolated and hydrolysed to nucleosides (JernstrBm et al 1980). Hydrolysed D N A was analysed on a reversed phase column (C18) using a methanoVwater gradient. Total benzo[a]pyrene modification of cellular D N A was estimated to be 20 pmoles/mg DNA. (b) Same conditions as above, except that the cells were isolated from phenobarbitone-treated rats and incubated with 20 pM [3H]benzo[a]pyrene for 30 min. Total benzo[a]pyrene modification of cellular DNA was estimated to be 5 pmoles/mg DNA. - and benzo[a]pyrene-7,8-dihydrodiol(retention time 46 minutes) can be identified (cf JernstrOm et a1 1980).
In contrast to the metabolism of carbon tetrachloride and bromobenzene, that of benzo[a]pyrene is affected primarily by 3-methylcholanthreneinduction. As shown in Table 3, pretreatment of rats with this inducer dramatically increases metabolism of benzo[a]pyrene by isolated hepatocytes, whereas pretreatment with phenobarbitone has only a minor effect. 4) containing 2% bovine serum albumin. The benzo[a]pyrene metabolites formed were analysed by high performance liquid chromatography (Burke et al 1977).
