| Abstract: | Studies have been made on the density of receptors and dissociation constants for dopamine D1- and D2-receptors in the striatum, n. accumbens with the olfactory tubercles and in the frontal cortex of Wistar rats, Norway rats and silver foxes. D1 binding was found to be significantly higher than D2 one in all the analysed brain structures of the animals studied, especially in the striatum. Although the analysis of D1- and D2-receptor binding kinetics revealed differences in Wistar and Norway rats, more significant differences were found between rats and silver foxes. |
