Abstract
A five-compartment closed model was established using the system of di fferential equations. The completely analytical solution of a five-com partment closed model was found using the Laplace transform. 2-[C-14]P yruvate kinetics were studied in rats without and with inhalation of v aporized ethanol, and were modelled by the five-compartment closed mod el, i.e. injected site, blood, eliminated (CO2)-C-14 in air, eliminate d C-14 in urine and faeces. The kinetic parameters were estimated usin g the analytical solution of the five-compartment closed model to fit eliminated (CO2)-C-14, and C-14 in urine and faeces simultaneously. Th e compartmental analysis showed that the inhalation of vaporized ethan ol can increase 2-[C-14]pyruvate trans-membrane, trans-tissue processe s and oxidation rate. The model developed is useful for general pharma cokinetic and toxicokinetic analysis as well as for studies on ethanol .
