International Journal of Molecular Sciences, 2016 Inhalation studies are the gold standard for the estimation of the harmful effects of respirable chemical substances, while there is limited evidence of the harmful effects of chemical substances by intratracheal instillation.

Nanotoxicology, 2016 In order to examine whether intratracheal instillation studies can be useful for determining the harmful effect of nanoparticles, we performed inhalation and intratracheal instillation studies using samples of the same nanoparticles.

International Journal of Molecular Sciences, 2016 We conducted inhalation and intratracheal instillation studies of zinc oxide (ZnO) nanoparticles in order to examine their pulmonary toxicity. F344 rats were received intratracheal instillation at 0.2 or 1 mg of ZnO nanoparticles with a primary diameter ...

We have described a unique example of intratracheal neurofibroma in a patient with neurofibromatosis. Although tracheal neoplasms are rare, they should be considered in the presence of obstructive respiratory symptoms. Careful scrutiny of plain roentgenograms with special views should be undertaken for optimal evaluation.

AbstractEctopic thyroid tissue within the trachea (intratracheal or endotracheal tissue) is a rare cause of upper airway obstruction. The symptoms may be classical or, as in most cases in which the voice is not affected, the first sign may be a wheeze. This may result in the symptoms being mistaken for asthma.

Ectopic intratracheal thyroid (EITT) is a rare abnormality, with few cases reported in the literature. We describe a case of a 36-year-old woman with dyspnea due to EITT. We also discuss the epidemiology, etiologies, presentation, diagnosis, and management of EITT.

Intratracheal Inhalation vs Intratracheal Instillation: Differences in Particle Effects
Fundamental and Applied Toxicology, 1997Our laboratory has developed a method of intratracheal inhalation whereby rats can be exposed to high aerosol concentrations, resulting in high lung particle burdens in a short time period with deposition occurring directly in the lower respiratory tract, thus avoiding many drawbacks of larger nose-only or whole body inhalation systems. In this report,
