Pulmonary lesions in livestock arise due to infection in the
respiratory mucosa and complications arising from myriad factors including host immune response, management, or environmental conditions (Chakraborty et al., 2014; Lacasta et al., 2008).
Histologic animal studies have confirmed this timeline, showing that
respiratory mucosa is restored by the 28th day after injury.
It is hypothesized that virus infected immune cells in the
respiratory mucosa migrate to the local lymphoid tissue, where it replicates and enters the general circulation (Herbert et al., 2014).
This kind of cold weather causes changes in our
respiratory mucosa, making it very dry and prone to an infection build-up.
The respiratory epithelial adenomatoid hamartoma (REAH) of the nasal cavity and paranasal sinuses is a benign lesion that arises from the
respiratory mucosa; it was first described by Wenig and Heffner (1).
[9] Exposure of formalin above permissible limit may create physiological modifications of
respiratory mucosa, which causes upper airway irritation, sore throat, tingling and burning sensations of the nose and nasal blockage.
Clinicopathologic differences in malignant melanoma arising in oral squamous and sinonasal
respiratory mucosa of the upper aerodigestive tract.
The turbinates are thin, curved, shelf-like bony projections, covered by
respiratory mucosa, in the lateral walls of the nose1.
Caption: Figure 3: A histologic specimen of
respiratory mucosa with thickened basement membrane and mild chronic inflammation.
As a result of the 8-week inhalation of xylene; The lining epithelium of
respiratory mucosa showed a loss of ciliated cells with metaplasia of goblet cells, hyperplasia of squamous cells and edema, inflamation in sub epithelial area.
