RESUMO
Objective To investigate the correlation between the CYP2E1 enzymes and alcoholic liver disease.Methods Polymerase chain reaction-restriction fragment length polymorphism(PCR-RFLP)method was used to determine polymorphism of CYP2E1.A case control study of 183 subjects was carried out including 40 cases of alcoholic liver disease,40 alcohol dependent group,40 nonalcoholic liver disease and 63 controls.Results The frequency of B genotype or C2 allele gene was significantly higher in alcoholic liver disease than in control(P
RESUMO
OBJECTIVE: Enzymes belonging to the Glutathione S transferase and cytochrome P450 families are involved in the two-stage detoxification process of a number of pro-carcinogens. We genotyped each 74 women with moderate or severe endometriosis and a control group of 93 women with a normal pelvis at cesarian section to investigate whether genetic polymorphism of CYP1A1, GSTT1, and GSTM1 are associated with endometriosis. MATERIALS AND METHODS: We investigate 74 women who were operated for endometriosis and 93 women who had no endometriotic lesion proved by operation. Polymerase chain reaction (PCR) and restriction fragment length polymorphism of PCR was done to determine each participant's genotype. RESULTS: We have found no significant differences between cases and controls in the frequencies of the GSTM1 and GSTT1 null mutations, or of the CYP1A1 MspI polymorphism does not differ significantly between groups. When GSTT1 and GSTM1 null mutation was combined with CYP1A1 MspI polymorphism, there was no significant differences between groups, either. CONCLUSION: Therefore, These low penetrance genes are not associated with increased susceptibility to endometriosis. Further studies are warranted to identify major susceptibility gene (s) and the mechanism involved in endometriosis to assist in the development of better methods for early detection, diagnosis and prevention.
