isolated parathyroid glands from normal adult mongolian gerbils were incubated for 15 minutes to 3 1/2 hours either at high or low concentrations of ca2+ and mg2+ after which they were studied ultrastructurally , using the pyroantimonate technique and x-ray analysis for identification and son concentrations were mainly composed of suppressed chief cells with moderate or high cytoplasmic density , sparsely developed endoplasmic reticulum , often large golgi complex , occassional cytoplasmic accumulations of secretory granules , lipoid bodies , glycogen-like particles , and numerous often large mitochondria .
