[Multiple human cord blood transfusion for inducing low immune response].

OBJECTIVE: To investigate and evaluate a clinically perspective way of inducing transplantation tolerance. METHODS: Multi-cord blood transfusion was performed before kidney transplantation in 20 cases. Donor-specific mixed lymphocyte reaction(MLR) and allograft rejection were observed and studied. RESULTS: The donor-specific MLR was suppressed in every recipient. No allograft rejection took place in the cord blood transfusion group three months after kidney transplantation. CONCLUSION: Multi-cord blood transfusion is a practical way of inducing transplantation tolerance.

Plasma polymerization of aniline on different surface functionalized substrates.

The plasma polymerization of aniline on different surface functionlized low-density polyethylene (LDPE) substrates was investigated, and the resulting polymer was characterized by X-ray photoelectron spectroscopy, Fourier transform infrared spectroscopy, scanning electron microscopy, and atomic force microscopy. The results showed that the structure of plasma-polymerized polyaniline was rather different from polyaniline synthesized by conventional chemical and electrochemical methods. This difference may be due to extensive coupling reactions and cross-linking reactions during the plasma polymerization process. The use of acrylic acid graft copolymerized LDPE substrate significantly enhanced the adhesion of the polyaniline to the substrate over that observed with pristine LDPE. The plasma polymerized polyaniline can be rendered electrically conductive if the polymerization is carried out on a polystyrenesulfonic acid-coated LDPE substrate. Conductivity can also be induced by acid protonation of the polyaniline by HClO(4). The reaction of the plasma-polymerized polyaniline with viologen grafted on the substrate under UV irradiation and with AuCl(3) and Pd(NO(3))(2) in acid solutions was also investigated.
