THE EFFECT OF AMINOMETHYLPTEROYLGLUTAMIC ACID ON THE DEVELOPMENT OF SKIN HYPERSENSITIVITY AND ON ANTIBODY FORMATION IN GUINEA PIGS

Abstract
1. In guinea pigs, aminomethylpteroylglutamic acid (methotrexate) is capable of blocking the development of delayed skin hypersensitivity, the primary antibody response, and the specific febrile response to ovalbumin and diphtheria toxoid. The primary antibody response is more easily inhibited than is the development of delayed skin hypersensitivity.
