Toxicity of Nicotine by Repeated Intratracheal Instillation to F344 Rats
In vivo, nicotine in cigarette smoke induces various effects not only on the respiratory system but also the central and peripheral nerve systems, circulatory organs and digestive organs, and there is a possibility of promotion of lung tumorigenesis. The present experiment was conducted to examine histopathological changes caused by nicotine in the lung with repeated intratracheal instillation ...
متن کاملPulmonary responses in rat lungs after intratracheal instillation of 4 crystal forms of titanium dioxide nanoparticles
OBJECTIVE Titanium dioxide nanoparticles are widely used as UV filters in cosmetics and as a photocatalyst. We evaluated pulmonary responses to different crystal forms of TiO2 nanoparticles. METHODS We used 4 different TiO2 samples with similar specific surface areas (anatase, rutile, amorphous, and P25). Each sample was suspended in distilled water and intratracheally instilled to male Wiste...
متن کاملIntratracheal instillation versus intratracheal inhalation: influence of cytokines on inflammatory response.
Our laboratory has developed a method of particle exposure whereby anesthetized rats intratracheally inhale, at a regulated breathing rate and pressure, an aerosolized test material. This method is capable of delivering considerable doses in a short time period and, unlike the commonly used method of intratracheal instillation, does so with an even particle distribution throughout the lung. Ear...
متن کاملReactive pleural inflammation caused by intratracheal instillation of killed microbes.
To investigate the pleural leucocyte response to severe alveolar inflammation, heat-killed Corynebacterium parvum were instilled intratracheally into the lungs of PVG rats and pleural lavage was performed. Polymorphonuclear neutrophils are not normally resident in the pleural space but were found transiently after intratracheal instillation of C. parvum. Macrophages increased gradually in the p...
متن کاملEffects of intratracheal instillation of TNF-alpha on surfactant metabolism.
Tumor necrosis factor-alpha (TNF-alpha) has been shown to play an integral role in the pathogenesis of the acute respiratory distress syndrome. This disorder is characterized by a deficiency of alveolar surfactant, a surface-active material that is composed of key hydrophobic proteins and the major lipid disaturated phosphatidylcholine (DSPC). We investigated how TNF-alpha might alter DSPC cont...
