    Notes: Abstract A flow-limited physiologic mathematical model has been developed to describe the time course of 2′deoxycoformycin (2′dCF) concentrations in the plasma and tissues of mice following iv and ip doses. Urinary excretion is modeled as a linear process involving filtration and secretion, since kidney clearance exceeded estimated glomerular filtration rate. Intracellular binding is described as the sum of linear nonspecific binding plus strong saturable binding to adenosine deaminase. Pharmacokinetic parameters are determined by a sequential optimization scheme in which each tissue is studied by means of a hybrid model. The model has been used to predict pharmacokinetic behaviour of 2′dCF in both normal and leukemic mice, and model simulations are compared with published data.

    Notes: Abstract We have examined the relationships between the genetic determinants for mouse β-galactosidase heat stability and electrophoretic mobility, in order to clarify previous reports indicating that a variation for enzyme heat stability is restricted to kidney while that for electrophoretic mobility is expressed in all tissues. We find that the two phenotypes show concordant strain distributions and cosegregate in genetic crosses. In contrast to a previous report, the thermal stability variation is expressed in all tissues, although the absolute rate of enzyme inactivation is tissue specific. The evidence supports the notion that a single β-galactosidase structural locus is expressed in all tissues and that the differences in enzyme stability between tissues results from posttranslational enzyme modification.

    Notes: Abstract Ornithine decarboxylase (ODC), the first enzyme in the polyamine biosynthetic pathway, is encoded by at least one member of a multi-gene family in the mouse. Analysis of a polymorphism in ODC structure in recombinant inbred strains has enabled assigning a functional ODC structural gene (Odc) to the proximal region of mouse chromosome 12 betweenApob andEs25. Linkage ofOdc toApob andAh is conserved in the mouse and human genomes.

    Notes: Abstract A physiological pharmacokinetic analysis ofcis-dichlorodiammineplatinum(II) (DDP) is presented for the rabbit, dog, and human. The results are compared to a previous analysis for the rat. DDP binds irreversibly to low-molecular weight nucleophiles and macromolecules to form mobile and fixed metabolites at rates which are tissue-specific. The rate constant for the formation of fixed metabolite in plasma, determined by in vitro incubation, ranges from 0.004 to 0.008 min−1.
