this research analyzed differences mainly in the incidence of exocytotic figures in adrenaline cells ( a-cells ) in pinealectomized ( px ) , sham-operated ( spx ) , and non-operated ( no ) adult male golden hamsters , with the aim of determining whether these parameters change with the time of day and following pinealectomy , and whether intracellular regional differences exist in such changes .
