Contact dermatitis from penetration of rubber gloves by acrylic monomer.

An orthopaedic surgeon developed dermatitis from acrylic materials. The acrylic monomer was found to penetrate surgical rubber gloves readily. Cases of "rubber glove dermatitis" with negative patch tests may have a similar explanation.

Lesions in Escherichia coli cell walls caused by the action of mouse complement.

Characteristic lesions formed by mouse complement were visible in electron micrographs of cell walls treated with aminoethylisothiouronium bromide and then incubated with normal mouse serum . However, lesions could not be detected in cell walls recovered from the blood of normal mice after intravenous injection. Lesions were not produced by either heated or complement deficient mouse sera in any of the experiments.

In vivo bactericidal activity of mouse complement against Escherichia coli.

Live of complement sensitive and resistant strains were labelled with C and injected i.v. into normal mice and into a co-isogenic strain deficient in C′5.
