Protective effect of barrier creams and spray coatings against epoxy resins.

This study evaluates the protective capacity of 4 barrier creams and 2 methacrylate spray coatings against skin contact with epoxy resins. The effect of these materials on the strength and on the surface area of patch test reactions caused by epoxy resin was assessed in 11 volunteers with a known allergy to epoxy resins. Standard amounts of barrier cream and spray coating were applied on the skin.

Plasma cells and their precursors. IV. Cross-reacting and non-cross-reacting, sheep erythrocyte lysing IgG antibody clones induced in rabbits immunized with rat- and chicken-erythrocytes.

Rabbits were i.v. immunized with rat erythrocytes or chicken erythrocytes.

Plasma cells and their precursors. III. Late phases of anti-bovine serum albumin IgG antibody responses depend upon newly produced IgG B-memory cells.

The sequential appearance of the IgG antibody clones constituting the primary, secondary or tertiary response to BSA was studied in individual rabbits by relating antibody titers, antibody affinities, and clonal spectra obtained by IEF. The results showed that after a single i.v.

Plasma cells and their precursors. II. Kinetics of B-memory cell production in rabbits.

Rabbits were irradiated with 4.5 Gy in order to eliminate completely preexisting antibody-forming cell precursors. Sheep red blood cells were administered 24 h or 8 days after irradiation in order to induce the production of IgG B-memory AFCP.
