E.2.2 | Secondary objectives of the trial |
Patient Group:study the metabolism of the active principles of the drug and indocyanine green test before and after chemotherapy before surgery,and determining differences.Results of HepatoTest will correlated with indocyanine green test performed before and after chemotherapy.Determine the pharmacokinetics of paracetamol active,dextromethorphan, chlorpheniramine and caffeine volunteer subjects.Liver biopsy study the amount and activity per gram of tissue of the enzymes involved in the metabolism of the active principles of the drug.To determine the relationship of the results of HepatoTest and indocyanine green test with the appearance of postoperative liver dysfunction.Determine the histological changes secondary to chemotherapy,and its relation to the type of chemotherapy received, the duration of treatment,and the occurrence of postoperative liver dysfunction.Study the correlation of preoperative HepatoTest result of hepatic enzyme activity in liver regeneration capacity |
