Lung inflammation causes

Chemical pneumonitis Inflammation of the lungs caused by accumulation of fluids due to chemical irritation. 

Mild exposure to HF via inhalation can irritate the nose, throat, and respiratory system. The onset of symptoms may be delayed for several hours. Severe exposure via inhalation can cause nose and throat bums, lung inflammation, and pulmonary edema, and can also result in other systemic effects including hypocalcemia (depletion of body calcium levels), which if not promptly treated can be fatal. Permissible air concentrations are (42) OSHA PEL, 3 ppm (2.0 mg/m ) as E OSHA STEL, 6 ppm (5.2 mg/m ) as E and ACGIH TLV, 3 ppm (2.6 mg/m ) as E. Ingestion can cause severe mouth, throat, and stomach bums, and maybe fatal. Hypocalcemia is possible even if exposure consists of small amounts or dilute solutions of HE. 

Bromothiophenes are toxic materials by aU routes. Inhalation toxicity of 2-bromothiophene is significant. Ecotoxicity is also noted for these materials, particularly for 2-bromo-3-methylthiophene. 2-Thiophenecarboxaldehyde and the 3-methyl derivative can cause minor irritation to the skin and eyes of rabbits. The former is a sensitizer to guinea pig skin, the latter is not. 2-Acetylthiophene is toxic in aU modes of contact. Severe exposure causes serious inflammation of the lung, damage to many organs, and depression of the central nervous system. 

Hypersensitivity Pneumonitis a group of respiratory diseases that cause inflammation of the lung (specifically granulomatous cells). Most forms of... 

State of deviation of plasma pH (systemic acidosis) or tissue extracellular pH (tissue or local acidosis) from normal (ca. pH 7.4) towards lower values. Deviation of 0.1 pH units is significant. Systemic acidosis can be caused by lung or kidney failure. Local acidosis can be the consequence of injury, inflammation, or tumor growth, due to disruption of blood supply. Local acidosis is normally associated with hypoxia. 

Nitrogen tetroxide is one of the most insidious gases in terms of human toxicity. Inflammation of the lungs may cause only slight pain or pass unnoticed, but the resulting edema several days later may cause death. lOOppm is dangerous for even a short exposure, and 200 ppm may be fatal (Ref 25). Also see under Nitrous Fumes in this Vol... 

Bauer, A. K. Dwyer-Nield, L. D. Hankin, J. A. Murphy, R. C. Malkinson, A. M. The lung tumor promoter, butylated hydroxytoluene (BHT), causes chronic inflammation in promotion-sensitive BALB/cByJ mice but not in promotion-resistant CXB4 mice. 

Pneumonia is inflammation of the lung with consolidation. The cause of the inflammation is infection, which can result from a wide range of organisms. There are five classifications of pneumonia community-acquired, aspiration, hospital-acquired, ventilator-associated, and health care-associated. Patients who develop pneumonia in the outpatient setting and have not been in any health care facilities, which include wound care and hemodialysis clinics, have community-acquired pneumonia (CAP). Aspiration is of either oropharyngeal or gastrointestinal contents. Hospital-acquired pneumonia (HAP) is defined as pneumonia that occurs 48 hours or more after admission.1,2 Ventilator-associated pneumonia (VAP) requires endotracheal intubation for at least 48 to 72 hours before the onset of... 

Recently, it has been shown that inhalation of MWNTs caused suppression of the systemic immunity without resulting in significant lung inflammation or tissue damage [82,83]. Inhaled MWNTs in fact modified the functionality of spleen cells in exposed mice [82]. Notably, the activity of cyclooxygenase (COX) enzymes in spleen was affected as a response to a cytokine (TGF(5) released from the lungs. This cytokine activated the COX pathway in the spleen, triggering T-cell dysfunction and systemic immunosuppression [83]. 

Headache, tachypnea, dizziness, confusion, and chest pain. The casualty may also experience palpitations, dyspnea on exertion, drowsiness, lethargy, hallucination, agitation, nausea, vomiting, diarrhea, and coma. If metal carbonyls have been released, there may be complaints of irritation of the eyes, mucous membrane, and respiratory system. Inflammation of lung tissue (pneumonitis) caused by metal carbonyls can may be delayed 12-36 hours. They may also cause injury to the liver, kidneys, and lungs as well as degenerative changes in the central nervous system. 

Local effects noted in guinea pigs, rats, mice, and hamsters caused by inhalation of metallic nickel powder (15 mg/m3), nickel subsulfide (0.97 mg/m3), or nickel oxide (53 mg/m3) include nasal sinus inflammations, ulcers, lung irritation, nickel accumulations in lungs, emphysema, and...
