Abstract

Delayed hypersensitivity to human and guinea pig sperm was demonstrated in guinea pigs of the Rockefeller strain by immunization with H~37~Ra adjuvant. The reaction in vivo was demonstrated by skin testing the animals and in vitro by the capillary method. It was found that the sensitivity is not only directed towards the sensitizing antigen, but also shows cross‐reactivity. Thus, peritoneal exudate cells derived from guinea pigs sensitized to human sperm were inhibited by guinea pig sperm. This cross‐reactivity revealed the possibility of a tissue specific antigen. In addition, supernatants obtained after incubation of the sensitized lymph node cells with the specific antigen were found to be spermatotoxic.

## Abstract Four‐hundred and fifty ninΓ© cancer patients were skin tested with extracts from five lymphoid cell lines. More than 50% of patients with lymphoma had positive skin tests with the extracts prepared from the cell line derived from Burkitt's lymphoma (BL) and more than 50% of nasopharyngea
