[Conditions for analysis of cytochrome p-450 activity in human liver microsomes].
Multiples forms of CYT-P450 have been isolated from human liver microsomes. The distribution of CYT-P450 could be correlated with pathologic and influence the individual's response to therapeutic drugs and susceptibility to the toxic and cancerogenic effects of environmental pollutants. The aim of the this work is to determine the amounts of CYT-P450's in small samples from human liver such as biopsies and eventually to correlate them with pathology. For these reasons, tests providing informations about the distribution of CYT-P450 in individual subjects are very important. In this study we have reviewed the method for measuring the activity of CYT-P450 and the dosage of Benzopyrene hydroxylase. We modified some of these methods for the study of CYT-P450 from human liver microsomes.
