EFFECT OF CADMIUM ON THE STRUCTURE OF THE ENDOPLASMIC RETICULUM OF THE HAMSTER PARATHYROID CHIEF CELLS / 解剖学报

With transmission electron microscopy,the endoplasmic reticulum of the parathyroid chief cells in normal and cadmium-treated golden hamsters was observed. After 1 month treatment of cadmium, there were dilated and whorl-shaped rough endoplasmic reticulum in the chief cells. After 3 and 6 months treatment of cadmium, there were concentric membranous body and paired endoplasmic reticulum in the chief cells. The mechanism responsible for the morphological change of the endoplasmic reticulum after cadmium treatment and the possible toxicologic effect were discussed.
