Age-dependent changes in the expression of muscarinic M1 and M2 cholinergic receptors were assessed in the CA1 and CA3 fields of hippocampus using radioligand binding and autoradiographic techniques with [3H]-pirenzepine and [3H]-AF-DX 116 as ligands. Male Wistar rats of 2 months (young), 12 months (adult) and 27 months (old) of age were examined.(More)
The present study was designed to investigate age-dependent changes of muscarcinic M1 and M2 cholinergic receptors in the rat hippocampus using radioreceptor assay and autoradiographic techniques with [3H]pirenzepine and [3H]AF-DX 116 as ligands. The analysis was performed on 2-, 12- and 27-month-old male Wistar rats, considered young, adult and old,(More)
To explore the relationship between beta-amyloid (A beta) and the pathogenesis of Alzheimer disease (AD), after injection of beta-amyloid into the rat brain, the apoptosis of nerve cells and acetylcholine (Ach) content in rat hippocampus were examined by employing TUNEL technique and base hydroxylamine colorimetry respectively. The influence of age and(More)
