The intensity of anaphylactic shock was lower in C3H mice carrying a methylcholanthrene-induced tumour (McC3) than in their normal counterparts when immunized with ovalbumin and challenged i.v. after 14 days. This tumour-associated inhibitory effect on active systemic anaphylaxis was exerted mainly on events occurring after homocytotropic antibody synthesis(More)
The growth of a 3-methylcholanthrene-induced fibrosarcoma of C3H mice was inhibited by aspirin and indomethacin. While the tumour contained relatively high concentrations of PGE2-like material, that were markedly diminished by indomethacin treatment, our results did not confirm the recently proposed hypothesis that the anti-tumour effect arises from a(More)
Mercury-induced autoimmunity in Brown-Norway rats has been shown previously to be due to polyclonal activation of B lymphocytes, requiring the presence of T lymphocytes. Autoimmunity in that strain is characterised by the appearance of an autoimmune glomerulonephritis, by the production of a host of autoantibodies, and by an increase in total serum IgE. In(More)
A procedure is described for the selection of glucose uptake mutants based upon radiation suicide of Chinese hamster fibroblasts by 2-deoxy[3H]glucose. In one of these mutants, DS 7, the ability to transport either 2-deoxyglucose or 3-O-methylglucose was decreased to one-fifth to one-fourth. Besides this defect, DS7 produces 1/14th the lactic acid produced(More)
Five recombinant DNA plasmids have been constructed that contain structural gene sequences for rat tyrosine hydroxylase [TyrOHase; tyrosine 3-monooxygenase; L-tyrosine, tetrahydropteridine:oxygen oxidoreductase (3-hydroxylating), EC 1.14.16.2]. Rat pheochromocytoma PC 12 cell line, which contains relatively high levels of catecholamine-synthesizing enzymes,(More)
Indomethacin was continuously administered in the drinking water of inbred C3H mice given grafts of syngeneic 3-methylcholanthrene-induced fibrosarcomas. A minor proportion of these animals died at the same time as the untreated controls, and others completely rejected their tumors; however, in most cases, the tumor growth rate was significantly slowed, and(More)
When an extracellular dye, Lissamine green, or 51Cr-labeled spleen cells were injected iv into C3H mice bearing small, partially necrotic 3-methylcholanthrene-induced transplantable fibrosarcomas (McC3), the tumor content of these circulating elements per unit weight was substantially lower than that of other selected organs. The level of these blood-borne(More)
C3H and C57 BL/6 mice carrying methylcholanthrene-induced fibrosarcomas were injected i.p. daily with histamine, metiamide (anti-histamine type-2 receptor), histamine + metiamide, mepyramine (anti-histamine type-1 receptor), serotonin and methysergide (anti-serotonin). Inhibition of tumour growth and lengthened survival were observed with histamine and(More)
