Area of Science:

  • Histotechnology
  • Pathology
  • Biomedical Research

Background:

  • Traditional tissue fixation and decalcification are time-consuming.
  • Efficient sample preparation is crucial for timely diagnosis and research.

Purpose of the Study:

  • To evaluate the efficacy of microwave (MW) irradiation for tissue fixation and decalcification.
  • To determine optimal MW treatment parameters for histological samples.

Main Methods:

  • Utilized a standard kitchen microwave oven for MW irradiation.
  • Applied MW irradiation to tissues in 10% formalin for fixation.
  • Applied MW irradiation to bone biopsies in 5% formic acid for decalcification.
  • Processed tissues using routine paraffin embedding and staining.

Main Results:

  • Microwave irradiation markedly reduced the time required for both tissue fixation and decalcification.
  • Established optimal time and power settings for MW-assisted fixation and decalcification.
  • Achieved satisfactory tissue preservation and morphology.

Conclusions:

  • Microwave irradiation offers a rapid and effective method for tissue fixation and decalcification.
  • The described protocol enables accelerated histological sample preparation.
  • This technique has the potential to improve workflow efficiency in pathology and research settings.
