Binding of tritiated ligands of muscarinic and dopamine receptors was analysed in rats 1, 7, 14, 28, 60 days and 24-30 months old. The following ganglia were studied: the nodose ganglion, the lumbar ganglia of sympathetic chain, the main pelvic ganglion in male rats and the paracervical ganglion in female rats. The same level was found for binding of each of ligands for all investigated ganglia. Parameters of postnatal dynamics of development M-cholino- and dopamine reception systems prove to be quite similar, but not identical. Both of the systems reach matured level during first 2 postnatal weeks. In comparison with quinuclidinylbenzilate binding failure of dopamine binding in aged rats is to be more pronounced. |
