Time-related changes in size of nuclei of pinealocytes in rats

Cell and Tissue Research, 1981
In a study of 96 adult male Sprague-Dawley rats, da- and time-related changes of the mean nuclear volume of pinealocytes were determined with the aim of testing the reproducibility of the karyometric findings described by Quay and Renzoni (1966). It is shown (i) that statistically significant differences exist between the central and peripheral mean ...

β-Adrenergic regulation of cyclic GMP in rat pinealocytes

Biochemical and Biophysical Research Communications, 1990
Stimulation of rat pinealocyte cyclic GMP by beta-adrenergic agonists (in the presence of prazosin to block alpha 1-adrenoceptors) showed an identical potency order (isoproterenol greater than epinephrine = norepinephrine much greater than salbutamol greater than terbutaline) to the stimulation of pinealocyte cyclic AMP.
