Opis:
The effect of adriamycin on the behaviour of CD4⁺ and CD8⁺ cells in the course of trichinellosis in mice has been studied. The animals infected with 200 larvae per mouse were administered intraperitoneally adriamycin (Adriblastin from Farmitalia) at 1st and 28th day post infection (dpi), in a dosis of 0.2 mg. The mice were killed weakly for 6 weeks and then at the 60th dpi. The examinations were made on histologic sections from the spleen, mesenteric lymph node, jejunum and masseter muscle using immunofluorescent and immunoenzymatic methods with monoclonal antibody. The mice receiving adriamycin exhibited more CD8⁺ cells in the intestinal mucosa and by the end of the experiment also in the muscles in comparison with the control animals, which, however, did not affect the course of the infection.

NADPH-cytochrome P450 reductase
Opis:
NADPH-cytochrome P450 reductase (P450 reductase) is one of the enzymes implicated in the metabolism of adriamycin, a very important clinically used antitumour drug. However, apart from the enzyme involvement, so far little was known about the chemical route and biochemical effects of this process. We demonstrated that the application of P450 reductase simultaneously with adriamycin to tumour cells in culture significantly increased cytotoxicity of the drug. Under tissue culture conditions, we noticed also that, in the presence of P450 reductase, adriamycin metabolite(s), displaying an altered spectrum within the visible light range were formed. This observation was taken adavantage of to study the metabolism of adriamycin in cell-free systems, using initially the enzyme isolated from rat liver and the recently obtained recombinant human P450 reductase. The reductive conversion of the drug turned out to be a multi-stage process, which occurred only under aerobic conditions and was accompanied by excessive NADPH consumption. Further research carried out with the aid of radical scavengers and radiolabelled adriamycin revealed that the enhancement of biological activity of adriamycin by P450 reductase stemmed from the formation of alkylating metabolite(s) rather than from the promotion of redox cycling known to be induced in the presence of anthracyclines.
