The effects of fumonisin B1 (FB1) on the immune system of Sprague-Dawley rats were investigated. Groups of male and female rats (10 rats/group) were gavaged daily for 14 days with doses of 0, 5, 15, and 25 mg/kg body wt/day and the primary (IgM) response to sheep red blood cells expressed as plaque-forming cell numbers/10(6) spleen mononuclear leukocytes(More)
Cross-reactivity between several commercially available mouse antihuman monoclonal antibodies (mAbs), conjugated to phycoerythrin (PE) and fluorescein isothiocyanate (FITC) fluorochromes, and peripheral blood leukocyte surface antigens, has been established in infant cynomolgus (Macaca fascicularis) monkeys using whole blood lysis, and two-color, PE and(More)
Human peripheral blood mononuclear leukocytes (PBML) proliferation was measured in the presence or absence of amphetamines. Proliferation in response to T-cell mitogen PHA was suppressed from 22 to 34% by d- and dl-amphetamine, respectively, contrarily to 1-form which did not affect proliferation of PHA-stimulated PBML. The 'designer' amphetamines appeared(More)
To determine the effect of HIV infection on the accessory cell function of monocytes we measured the ability of HIV-infected monocytes to restore PHA-induced and soluble anti-CD3-induced T cell blastogenesis. These T cells were highly purified and depleted of monocytes (< 0.5%) and activated T cells. Monocytes were isolated using gelatin-fibronectin-coated(More)
A new method for the fixation of polymethacrylate monoliths within titanium tubing of up to 0.8 mm I.D. for use as a chromatographic column under elevated temperatures and pressures is described. The preparation of butyl methacrylate-ethylene dimethacrylate-based monolithic stationary phases with desired porous structures was achieved within titanium tubing(More)
Selected immune function parameters were examined in male Fischer 344 rats following (a) induction of enzyme-altered preneoplastic liver foci (EAF), and (b) growth modulation of EAF by 30-day feeding with the food antioxidant butylated hydroxytoluene (BHT). Glutathione S-transferase-P (GSTP)-positive EAF were observed in livers of rats receiving(More)
Toxaphene in glycerol/corn oil was administered at 1mg/kg body weight/day, 7 days/week in gelatin capsules to four healthy young adult cynomolgus (Macaca fascicularis) (two male and two female) monkeys for 52 weeks. Control monkeys ingested glycerol/corn oil only. Testing for immune effects was initiated at 34 weeks of treatment. Results included: reduced(More)
