A01 Concentrations of lymphocyte muscarinic receptors (MR), platelet α2-adrenoceptors (α2-AR) and blood monoamines in the ageing dog.

The article presents a study that aims to measure the concentration of lymphocyte muscarinic receptors (MR), platelet α2-adrenergic receptors and blood monoamine levels in ageing dogs. The study used 27 healthy dogs of both sexes divided into two groups: adults and old dogs. Blood samples were collected and the plasma catecholamines and serum serotonin was measured. The results suggest that both MR and serotonin levels represent appropriate marker of ageing in dogs.
