Respiratory System

Nose, Epithelium - Accumulation, Hyaline Droplet

    Narrative
    Nose, Respiratory epithelium - Accumulation, Hyaline droplet in a female B6C3F1/N mouse from a chronic study. The respiratory epithelium and cells of the mucosal gland contain eosinophilic globular material.
    Nose, Olfactory epithelium - Accumulation, Hyaline droplet in a female B6C3F1/N mouse from a chronic study. The turbinate epithelial cells contain homogeneous hyaline material. Image provided courtesy of Dr. R. Miller.
    Nose, Respiratory epithelium - Accumulation, Hyaline droplet in a female B6C3F1/N mouse from a subchronic study (left) and normal nasal respiratory epithelium from a control animal (right). Minimal accumulation of hyaline droplet material is present respiratory epithelium at the respiratory and olfactory epithelial junction of the septum in the treated animal (left), but not in the control mouse (right).

    Nose, Respiratory epithelium - Accumulation, Hyaline droplet in a treated female B6C3F1/N mouse (right) and a normal control female B6C3F1/N mouse from a subchronic study (left). Hyaline droplet material is present in the respiratory epithelial cells lining the nasopharyngeal duct from the treated mouse (right) but not in the control mouse (left).
