Abstract:
The reactivity of bovine retinal resistance arteries (i.d. ca. 200 microns) to selective alpha 1-, beta- and combined alpha- and beta-adrenoceptor stimulation was studied in vitro using phenylephrine, isoproterenol and norepinephrine, respectively. The results indicate that only functional alpha 1-adrenoceptors, possibly in low numbers, are present in these vessels.
