A bovine colostral antibody against verotoxin (VT) 2 of Escherichia coli O157:H7 was administered orally to beagle dogs. The antibody remained in the dogs' small intestine for at least 2 h, whereas little serum antibody remained 1.5 h after administration. Furthermore, the antibody activity of secretory IgA did not change until 2 h after administration;(More)
We used a 20-mer antisense oligonucleotide against human MDR1 mRNA to study the mechanism of uptake of oligonucleotides by a human colorectal adenocarcinoma cell line, HCT-15.5'-end-32P-labeled oligonucleotides were mainly used. The uptake of phosphodiester oligonucleotides (D-oligo) by HCT-15 cells increased with time, but the uptake of phosphorothioate(More)
Synthesis of α2-macoglobulin (α2M) by 3-week-old juvenile rats was compared to that of mature 7- and 11-week-old rats. Serum concentrations of α2M, interleukin (IL)-6- and cytokine-induced neutrophil chemoattractant (CINC)-1 were measured by enzyme-linked immunosorbent assay. The area under the concentration vs. time curve (AUC) for α2M was significantly(More)
Nine murine monoclonal antibodies (MAbs) raised against recombinant soluble intercellular adhesion molecule-1 (sICAM-1) were evaluated by means of ELISAs, and their neutralizing activity was investigated in two bioassays employing Raji cells activated with phorbol myristate acetate. Three of the MAbs inhibited autoaggregation of the activated cells and(More)
We have produced a chimeric bispecific antibody that has dual specificity of human fibrin and urokinase-type plasminogen activator (u-PA). Complementary DNAs for variable regions of both anti-fibrin and anti-u-PA antibodies were cloned from two murine hybridomas secreting respective antibodies using polymerase chain reaction (PCR) techniques, and joined to(More)
The half-lives of typical acute phase proteins in rats and beagle dogs during acute inflammation were investigated. Acute inflammation was induced by injection of turpentine oil in rats and administration of indomethacin in beagle dogs. Serum concentrations of α2-macroglobulin (α2M) and C-reactive protein (CRP) were measured by enzyme-linked immunosorbent(More)
