SENSITIZATION OF GUINEA PIGS TO CHROMIUM SALTS

[摘要] Techniques are outlined for the consistent production of delayed hypersensitivity to Cr in guinea-pigs. Cross-reactions among various hexa-valent and trivalent salts are readily elicited when differences in percutaneous absorption are obviated. A theory of sensitization to Cr is presented which may clarify the controversy over valency and explain the differences observed clinically and experimentally.
