Metabolism of trichloroethylene.
A major focus in the study of metabolism and disposition of trichloroethylene (TCE) is to identify metabolites that can be used reliably to assess flux through the various pathways of TCE metabolism and to identify those metabolites that are causally associated with toxic responses. Another important issue involves delineation of sex- and species-dependent differences in biotransformation pathw...
متن کاملTrichloroethylene exposure. Simulation of uptake, excretion, and metabolism using a mathematical model.
The absorption, distribution, and excretion of trichloroethylene, as well as the kinetics of formation and elimination of trichloroethanol (TCE) and trichloroacetic acid (TCA) were simulated by a mathematical model. The results of this model have been satisfactorily compared with those obtained experimentally from pulmonary elimination of the solvent and from urinary excretion of the metabolite...
متن کاملMetabolism of trichloroethylene and tetrachloroethylene in human subjects.
A linear correlation exists between the trichloroethylene concentration in the work environments and the level of total trichloro compounds in the urine of the workers, as expressed by the equation: Gamma = 7.25=chi + 5.5, where Gamma is trichloroethylene in air (ppm) is Chi is total trichloro compounds in urine (mg/l). Trichloroethanol level is also linearly related to trichloroethylene concen...
متن کاملGuanine uptake and metabolism in Neurospora crassa.
Guanine is transported into germinated conidia of Neurospora crassa by the general purine base transport system. Guanine uptake is inhibited by adenine and hypoxanthine but not xanthine. Guanine phosphoribosyltransferase (GPRTase) activity was demonstrated in cell extracts of wild-type germinated conidia. The Km for guanine ranged from 29 to 69 micro M in GPRTase assays; the Ki for hypoxanthine...
متن کاملCadmium uptake and metabolism in cultured cells.
Cultured cells have been made resistant to otherwise lethal concentrations of the toxic Cd ion, probably by induction of metallothionein (MT) synthesis and binding of Cd to the MT. One human epithelial cell line (HE) and two enzyme-deficient mutants of mouse fibroblasts (L-cells) (Cl 1D and A9) and their Cd-resistant substrains with a high content of MT, have been used to study cellular Cd upta...
