title: [Immunological study of the actions of auxiliary antitumor agents--effects on lymphocyte transformation reaction and natural cytotoxicity activity in nude mice].
abstract: P-aminobenzoic acid-N-xyloside (K-247) and dimethyl-2- (tetrahydro-2-furanyl) ethylsulfonium-p-toluene sulfonate (GT-101) were tested their in vivo effects on both mitogen-induced lymphoproliferative reactions and natural cell-mediated cytotoxicities in BALB/c nude mice (homozygous and heterozygous) spleen lymphocytes. The animals were injected i.p. either 400 mg/kg of K-247 or 5 mg/kg of GT-101 (for 7 days consecutively). GT-101 caused a positive increase in lymphoproliferations by PHA and SPA, while the administration of K-247 had no effect on PHA-and SPA-induced lymphoproliferations. Furthermore, in a 12-hour 51Cr release assay, both drugs had no effect on the natural cell-mediated cytotoxicity against YAC-1 cells.
