Only plasma was sampled from these animals. Values are mean (±coefficient of variation) for four rabbits for all doses except the 10-mg/kg dose, for which the values are for three rabbits.
The rate constant range is given in brackets.
All delay rate constants [i.e., L(7,2), L(14,7), L(15,14), L(16,15), L(17,16), and L(2,17)] for the nonlinear tissue uptake were set equal to P(10) for each rabbit, the slowest turnover time.
The value was fixed at a lower dose; therefore, no percent coefficient of variation is reported for these doses.
RBC areas were derived from the best-fit curves for ABLC concentrations plasma.
