[Microwaves in morphologic examinations: technologic progress or whim?].

Abstract

Microwave-ovens shorten the time and eliminate or reduce the formaldehyde concentration in the process of tissue-fixation for light- and electron microscopy. These devices can be also applied in dehydration, and in impregnation of tissues with paraffin as well as in staining of paraffin or cryostat cut-slices. The use of microwaves improves results of immunohistochemical and ultracytochemical stainings. The best results are given by precise laboratory microwave-devices, but domestic microwave-ovens can be also used in this procedure.
