'Routine' stains on osmicated resin embedded hepatic tissue.

Area of Science:

• Histopathology
• Biochemistry
• Diagnostic Pathology

Background:

• Accurate lipid quantitation in liver biopsies is crucial for diagnosing various liver diseases.
• Traditional methods for lipid demonstration may not be compatible with subsequent diagnostic staining.

Purpose of the Study:

• To evaluate a modified osmium tetroxide staining method for lipid demonstration in diagnostic liver biopsies.
• To assess the utility of this method for simultaneous lipid quantitation and routine histopathological analysis.

Main Methods:

• A modified osmium tetroxide technique was applied to routinely processed liver biopsy sections.
• Unstained sections were utilized for quantitative lipid analysis.
• Sequential sections were stained using standard liver histopathological stains.

Main Results:

• The modified osmium tetroxide method effectively demonstrates lipids in liver biopsies.
• Lipid quantitation can be performed on unstained sections.
• Sequential sections allow for correlation with routine diagnostic stains.

Conclusions:

• The modified osmium tetroxide method is a valuable tool for diagnostic liver biopsy analysis.
• This technique facilitates comprehensive evaluation of liver tissue, combining lipid quantitation with standard histopathology.
