Effects of dexamethasone, levamisole, or combined dexamethasone-levamisole administration on polymorphonuclear neutrophil (PMN) function in healthy, adult female goats were studied. Goats were assigned to treated (n = 6) and control (n = 6) groups. In experiment 1, treated goats were given levamisole (6 mg/kg of body weight, IM). In experiment 2, treated(More)
The response of mammalian monocytes and macrophages to bacterial lipopolysaccharide (LPS) may be influenced by serum factors that increase or decrease the propensity of LPS to bind to cell surfaces. We used fluorescence flow cytometric analysis to investigate the capability of bovine peripheral-blood leukocytes to bind LPS in the presence or absence of(More)
Response of vertebrates to bacterial lipopolysaccharide (LPS) may be regulated, in part, by serum factors that influence the bioavailability and cellular binding affinity of LPS. Using 3H- or 14C-labeled LPS, or a novel fluorescence-based assay for detection in CsCl isopycnic density gradients, our studies indicate the existence of factors in adult and(More)
Recombinant canine granulocyte colony-stimulating factor (rcG-CSF) was administered to clinically normal dogs, cyclic-hematopoietic dogs, and dogs undergoing autologous bone marrow transplantation, to determine whether rcG-CSF could be used to stimulate WBC production and function in normal and neutropenic dogs. To the normal dogs, rcG-CSF was administered(More)
Three cats were diagnosed as hyperthyroid based on clinical signs, historical findings, laboratory abnormalities, and basal serum thyroxine (T4) concentrations, and/or nuclear thyroid scans. Additionally, a presumptive diagnosis of thyroid carcinoma with pulmonary metastasis was made in each cat based on radiographic or scintigraphic evaluation. All three(More)
Viscosity of synovial fluid (SF) from 29 clinically normal horses was determined by use of a rotational cone and plate microviscosimeter. Total protein concentration in the SF of the 29 horses, as measured with a refractometer, was less than 2.5 g/dl. When the Coomassie brilliant blue test was used to determine total protein concentration in SF for 15(More)
Several issues remain to be resolved before the efficacy of various approaches to elicit anti-tumor immunity in patients can be evaluated. First, in vitro assays able to detect responses by T cells primed in vivo are needed. Second, a source of tumor antigen to stimulate patients' lymphocytes in vitro is required. The ELISPOT assay is attractive, because it(More)
Dexamethasone was administered at sequential dosages of 0.1 mg/kg/day for 3 days and 1 mg/kg/day for 3 days to 6 adult female goats. The greatest effects induced were hypokalemia, hypophosphatemia, and hyperglycemia. At low dosages of dexamethasone, transient increases (P less than 0.05) developed in serum sodium and chloride concentrations. An effect on(More)
Polymorphonuclear neutrophils (PMN) were isolated from the blood of healthy adult female goats on each of 3 consecutive days. The PMN isolated were evaluated, using random migration, chemotaxis, Staphylococcus aureus ingestion, cytochrome C reduction, iodination, and antibody-dependent cell-mediated cytotoxicity assays. Over the 3 days, mean values for each(More)
