تثبيت الرئة تحت الضغط المستمر لتقييم انتفاخ الرئة في الفئران

Overview

This protocol outlines a method for lung fixation that ensures stable conditions for histological evaluation of lung specimens from a mouse model of emphysema. The technique allows for the fixation of multiple lungs simultaneously without collapse or deflation.

Key Study Components

Area of Science

• Neuroscience
• Biology
• Histology

Background

• Emphysema is a lung condition often induced by cigarette smoke.
• Histological evaluation is crucial for understanding lung pathology.
• Maintaining lung inflation during fixation is essential for accurate assessment.
• This protocol addresses challenges in lung fixation techniques.

Purpose of Study

• To present a reliable method for lung fixation.
• To facilitate the evaluation of lung specimens in research.
• To improve consistency in histological analysis of emphysema models.

Methods Used

• Use of a fixation device that maintains constant pressure.
• Incision along the medial line of the mouse to access the thoracic cavity.
• Puncturing the diaphragm to open the thoracic space.
• Visualization of lungs and heart for specimen collection.

Main Results

• Successful maintenance of lung inflation during fixation.
• Ability to fix multiple lungs simultaneously.
• Stable histological specimens suitable for evaluation.
• Demonstration of the procedure by a graduate student.

Conclusions

• The protocol provides a reliable method for lung fixation.
• It enhances the quality of histological evaluations in research.
• This technique can be applied to various studies involving lung pathology.
