Our previous study demonstrated that Lewis (LEW) rat recipients engrafted with Brown-Norway (BN) rat liver displayed a long-term graft survival and that phenotypic and functional analyses of graft-infiltrating cells on day 6 postgrafting showed a lower proportion and activity of cytotoxic cells in long-term surviving hosts than LEW recipients engrafted with(More)
A novel macromolecular prodrug of Tacrolimus (FK506), FK506-dextran conjugate, was developed and its physico-chemical, biological and pharmacokinetic characteristics were studied. The conjugate was estimated to contain 0.45% of FK506 and the coupling molar ratio was approximately 1:1 (dextran-FK-506). Adsorption experiments using ion exchangers indicated(More)
In order to elucidate the immunological characteristics of rat liver transplantation, graft-infiltrating cells (GIC) isolated from rat hepatic allografts were analyzed phenotypically and functionally. GIC from long-surviving recipients (Brown Norway livers into Lewis hosts) and acutely rejecting recipients (DA livers into Lewis hosts) were compared. The(More)
To isolate fetal cells from maternal blood, we developed a new method based on galactose-bearing conjugation. Nucleated red blood cells (NRBCs), which highly express galactose on their surface, were selectively attached to a substrate coated with a galactose-containing polymer via soybean agglutinin (SBA), a galactose-specific lectin. Cord blood samples(More)
