to compare the intracellular distribution of beta-adrenoceptors in isolated myocytes of shr with that of age-matched wky and to examine changes in the distribution with aging , we measured the number of cell surface and total beta-adrenoceptors in 6- ( young groups ) and 37-week old ( old groups ) shr and wky .
