    摘要: The present invention provides a method for increasing the efficacy of antifolates which act via inhibition of dihydrofolate reductase (DHFR). The method comprises the steps of administration of 5-amino-4-imidazolecarboxamide riboside (Z) or its base with the antifolate such that the targeted cells are exposed to both the antifolate and Z simultaneously. This results in increased influx of the antifolate. For MTX, accumulation of the more biologically active polyglutamate forms is also potentiated. This potentiation appears to be mediated by an effect on the RFC.

    摘要: A plant growing system is provided wherein a layer of sand is placed between two water-impermeable layers. The top impermeable layer covers the entire sand surface and is formed of a thin opaque plastic. Each container for a plant has prongs extending from the bottom which, when positioned on the top sheet, extends into the sand layer without contacting the bottom water-impermeable layer. Water and nutrients are metered into the sand layer which is transmitted into the containers by capillary action.
