Morphology of the Golgi apparatus in streptozotocin-diabetic rat liver.

The altered morphology of the Golgi apparatus in streptozotocin-diabetic rat liver is described in situ and in preparations of the Golgi-membrane-enriched fraction. The main differences, as compared with controls, are a diminished Golgi apparatus area, the rounding of stacks of cisternae and the absence of secretory vacuoles with VLDL granules. These findings are discussed in view of biochemical alterations found previously in the Golgi-membrane-enriched fraction isolated from streptozotocin-diabetic rat liver.
