title: [Effect of methylglyoxal bis(guanylhydrazone) in combination with antifolic acid preparations on the biochemical indices and growth of Pliss lymphosarcoma in rats].
abstract: It was shown in experiments with Pliss' lymphosarcoma in rats that antifolates--cis-2,5-bis (aminohydroxymethyl)-piperazine-3,6-dione and methotrexate--cause tumor cell spermidine level to drop. Also, treatment with antifolates prevented the undesirable accumulation of S-adenosylmethionine in tumor cells induced by methyl-glyoxal-bis (guanylhydrazone) which inhibits polyamine biosynthesis. In chemotherapeutic experiments with rat lymphosarcoma, antifolates markedly potentiated the antitumor effect of methylglyoxal-bis (guanylhydrazone). The data suggest that the combination of polyamine biosynthesis inhibitors such as methylglyoxal-bis (guanylhydrazone) and alpha-difluoromethylornithine and antifolates may be useful in tumor chemotherapy.
