Depression or its treatment with antidepressant agents may have an impact on the normal function of the immune system. To address this issue in an animal model, we studied the effect of maprotiline and desipramine treatment of mice on several immunological activities associated with host resistance to cancer and infections. Our results indicate that chronic(More)
A rapid and specific high-performance liquid chromatographic (HPLC) assay has been developed for the determination of enviradene, 1, at concentrations of 2-5 ng/mL in plasma. The drug was extracted from the samples using benzene. The benzene extract was evaporated and the residue dissolved in the mobile phase. The HPLC system consisted of a reversed-phase(More)
Erythromycin fluxes into rabbit midjejunal segments were studied. When erythromycin was infused into the jugular vein of anesthetized rabbits, the antibiotic was secreted into the segments at a rate of 0.0136 +/- 0.0023 mg/min. Preloading of the segments with five and 20 times the plasma concentration did not diminish this secretion. Protein binding of the(More)
The metabolic fate of the orally effective cephalosporin antibiotic cefaclor (Lilly 99638) has been studied in rats, mice, and dogs. Cefaclor is efficiently absorbed from the gastrointestinal tract as the intact antibiotic. In rats and mice, cefaclor, for the most part, escapes metabolism in the body and is eliminated unchanged as unaltered antibiotic,(More)
LY210825, a recombinant tissue-type plasminogen activator (rt-PA), which contains the kringle-2 and serine protease functional domains of native tissue-type plasminogen activator, was previously produced by site-directed mutagenesis in a Syrian hamster cell line. We studied the thrombolytic potential of this molecule in a canine thrombosis model. Male(More)
Intermale aggression is a natural form of psychosocial stress that can alter a variety of physiological functions, including immune function. In Experiment 1, daily fighting between pairs of previously isolated male mice differentially altered immunological measures of T-cell responsiveness in dominant and submissive animals. Submissive mice had lower(More)
