Glucose-6-Phosphatase (G6Pase) was regarded as a marker enzyme of the endoplasmic reticulum in a number of different cells. The purpose of this report is to study the localization of G6Pase activity in the rat left ventricular myocardial cells. G6Pase activity was found in the lumen of the nuclear envelope, the sarcoplasmic reticulum(SR) and the subsarcolemmal cisterns. The SR tubules between the adjacent myofibrils displayed characteristic distribution on their longitudinal profiles, as a curtain-like network, the tubules appeared to be tight network facing A-band, whereas tubules formed large polygonal meshes facing I-band. It is thought that the SR tubules facing A- and I-bands, respectively, represented an adaptation of SR to the selective shortening of the myofibrils at the I-band during contraction.

Left ventricular myocardial hypertrophy was produced in the rats by ligation of the abdominal aorta below the diaphragm for seven weeks.Ultrastructurally, it was observed that the nucleus and nucleolus were enlarged, and the density of the chromatin of the hypertrophied myocardial cells was decreased. Free ribosomes and endoplasmic reticulum were increased. Golgi apparatus was well developed and was increased in number.Cytochemically, G6Pase activity was localized in the lumen of the sarcoplasmic reticulum, nuclear envelope and subsarcolemmal cisterns, and it was also positive in the regenerative rough endoplasmic reticulum. TPPase activity appeared in the Golgi apparatus, and it was especially prominent in the Golgi apparatus of the hypertrophied cells.These findings suggest that the protein synthetic activity was increased in the hypertrophied myocardial cells.
