We have demonstrated that T lymphocytes from the spleens of adult guinea pigs sensitized to group A streptococcal antigens are cytotoxic for cultured fetal guinea pig heart cells. Lymphocyte cytotoxicity, measured by 51Cr release from target cells, was stimulated by sensitization in vivo with group A whole cells, cell walls, and purified protoplast(More)
5'-nucleotidase activity, arachidonate metabolism and adenosine uptake were measured in P388 murine leukaemia cells and in a subline resistant to doxorubicin. These membranes related activities were found to be increased in the doxorubicin resistant cell line, compared to the drug sensitive cells. It is suggested that these differences do not play a role in(More)
