Abstract:
The methods of morphometry,histologic fluorescence quantification and quantita-tive histochemistry,RNA content,lipofuscin (Lp) content,nucleolar volume andneuron number (cells/250?m) were applied in the study of neurons in hippocampalCA_3 area in 4 age groups of Wistar rats (1,3,17,30 months).RNA content,nucleolar volume and neuron number decrease with advancingage.The difference between adult (17 months) and aged (30 months) rats weresignificant (P
