Polyamines are important for protein synthesis and tissue growth. In rat salivary glands, the activity of ornithine decarboxylase (ODC), the enzyme catalysing the formation of putrescine, and the content of putrescine, spermidine, spermine and N1-acetylspermidine were assayed after parasympathetic or
Putrescine (a diamine) raises the thermal denaturation temperature of mononucleosomes but produces only minor changes in the overall shape of the thermal denaturation curve. This is similar to the effect of sodium ions and is consistent with nonspecific binding to

Polyamines are polycations in cells and acetylation is the first step in their intracellular metabolism. We investigated the effects of the acetylated polyamines on arterial blood pressure and vascular reactivities in rats. Acetylspermine and acetylspermidine, administered at concentrations ranging from
