We developed a method to successfully remove, process, section, and stain, for histopathological evaluation, mammary tissue that had originally been fixed on slides as whole mounts. This method may promote the collection and evaluation of mammary gland whole mounts in reproductive and developmental test guideline studies.

This paper describes a striaghforward and efficient method of intubating mice for pulmonary function measurements or pulmonary instillation, that allows the mice to recover and be studied at later times. The procedure involves an inexpensive fiberoptic light source that directly illuminates the trachea.

Lung Capacity

The air in the lungs is measured in volumes and capacities. Lung volume measures reflect the amount of air taken in, released, or left over after a lung function, like a single inhalation. Lung capacity measures are sums of two or more lung volume measures. There are four defined lung volume measures: tidal volume, inspiratory reserve volume, expiratory reserve volume, and residual volume. Tidal volume is the amount of air inhaled and exhaled in a normal breath. Inspiratory...

FAQs
Several mechanisms can alter lung structure in overlapping ways. Inflammation may bring cellular accumulation, infection may change tissue locally, and fluid or fibrosis can increase or distort the affected area. Tissue destruction and uncontrolled cell proliferation create additional patterns. Because these mechanisms may look similar on initial imaging, clinicians combine structural findings with laboratory results and clinical information when available.
The underlying process determines the clinical interpretation and next steps. Inflammation or infection may indicate an active respiratory condition, whereas fibrosis can represent residual structural change. A benign or malignant growth raises different diagnostic and treatment considerations. Separating these possibilities supports a more focused differential diagnosis rather than treating every abnormal area as evidence of the same disease.
Clinicians consider how the abnormality appears on chest imaging, whether its characteristics suggest a particular tissue process, and whether it changes during follow-up. Laboratory testing can add information when infection or inflammation is being considered, while biopsy may provide direct tissue evidence. These assessments help determine whether observation, additional testing, or treatment planning is appropriate.
Chest radiography can identify an abnormal area in the lungs, while computed tomography provides a further imaging approach for characterizing it. The two methods support clinical assessment of the lesion’s structural appearance and help guide decisions about laboratory testing or biopsy. Their findings contribute to differential diagnosis, cancer risk assessment, and monitoring over time.
Additional testing is considered when imaging alone does not adequately establish the lesion’s cause. Laboratory testing may contribute evidence about processes such as infection or inflammation. When direct examination of tissue is needed, biopsy can help distinguish among scarring, other nonmalignant changes, and malignant growth. The resulting information can refine diagnosis and influence treatment planning.
Repeat assessment allows clinicians to determine whether the lesion changes, remains stable, or develops findings that require renewed investigation. Monitoring can be performed with imaging and may be supplemented by laboratory testing or biopsy when indicated. This longitudinal information supports cancer risk assessment, helps evaluate respiratory disease, and contributes to decisions about ongoing management.
