Abstract

Rat parathyroids fixed by microwave enhancement, i.e. microwave irradiation in the presence of glutaraldehyde for 8 s and postfixation with OsO4 after a delay of 5 min, were compared with parathyroids fixed by perfusion with glutaraldehyde followed by immersion in glutaraldehyde and finally in OsO4. Morphometric analysis revealed that microwave enhanced fixation led to a larger mean cell volume, to larger cell surface area, and to larger surface area in membranes of RER and secretory granules. Though it is not known by which method parathyroid cells are conserved closer to the living state it is obvious that microwave enhanced fixation retains more membranes but provokes centrifugal dislocation of membranes mimicking exocytosis.
