The extent to which this mechanism contributes to the development of toxic lung damage is unknown skin care books generic cleocin gel 20 gm online. Acute pulmonary edema may occur within a few hours of ingestion of paraquat, and pulmonary fibrosis and death typically occurs 1À3 weeks after ingestion of lethal amounts of paraquat. Immune-Mediated Toxicity Both physical and immunological mechanisms are important in pulmonary defense against chemical and infectious agents. However, the immune response may result in an adverse effect if hypersensitivity reactions, immune suppression, or nonimmunological enzymatic injury occur (Table 14. Hypersensitivity diseases or allergies are the most common types of immunemediated respiratory disease caused by inhaled agents. The four types of hypersensitivity reaction are discussed in Chapter 12, Immune System. Exposure to pulmonary sensitizers, either foreign proteins or simple chemicals that act as haptens, at sufficiently high concentrations induces the formation of specific antibodies. Initial exposure to the allergen or sensitizer induces production of IgE antibodies, which bind to mast cells and basophils. Platelet activation factor causes platelet aggregation and release of histamine, heparin, and vasoactive amines, thus further amplifying the response. Eosinophils and neutrophils, attracted by eosinophil chemotactic factor of anaphylaxis and neutrophil chemotactic factors, release hydrolytic enzymes that cause tissue necrosis. Chemicals that produce a Type I reaction include toluene diisocyanates, trimellitic anhydride, and platinum salts. Numerous pharmaceutical agents have been implicated in Type I reactions, but -lactam antibiotics and sulfa-containing drugs are the most common causes of drug-induced Type I reactions. Penicillin is thought to cause approximately 75% of fatal anaphylactic reactions in the United States. Organic dusts containing spores of thermophilic bacteria, true fungi, or animal proteins are the most common cause of hypersensitivity pneumonitis in people. The initial alveolitis may progress to chronic fibrotic lung disease with granulomas. In rats, however, the granulomas induced by beryllium are considered foreign-body type granulomas, and beryllium-specific T cells are not found. Immune suppression due to inhaled air pollutants has been documented in humans through epidemiological studies and in experimental animals, primarily through bacterial infectivity models, for agents that include oxidant gases such as ozone, nitrogen dioxide, and sulfur dioxide (see Chapter 12: Immune System), tobacco smoke, benzene, toluene, and metals such as arsenic, cadmium, nickel, zinc, and lead. Effects on the physical and innate (nonspecific) lung defense mechanisms frequently cannot be separated in these studies, but various studies have demonstrated adverse effects on the mucociliary apparatus, pulmonary surfactant, and macrophage function.

These types of direct injuries will ultimately lead to collapse of the mucous barrier because the mucous gel alone skin care tips for men 20 gm cleocin gel order otc, without constant renewal, cannot protect the mucosa and support rapid recovery after epithelial cell damage. Repair of chemically or mechanically induced gastric epithelial cell discontinuities can be complete within 30À90 minutes of injury. For example, gastric mucosa experimentally damaged by exposure to high concentrations of sodium chloride, which produces direct structural damage, can be repaired over a period of 6 hours by a gradual process of restitution of epithelial integrity via migration of cells from the gastric glands. Cellular proliferation is a key epithelial cell mechanism in maintaining mucosal barrier function. The extent of general mucosal damage resulting from an insult can be anticipated based on the amount of damage the compound inflicts on proliferating cells of the mucosa. These various interactions allow the gastric mucosa to resist the damaging effects of the low pH environment and toxic compound exposure. However, severe mucosal damage will occur when the proliferating unit of the mucosa is destroyed. Such injury develops after irradiation, exposure to some mycotoxins, or administration of cytotoxic drugs. Modifications of epithelial cell proliferation maybe the only morphological indication of mucosal injury. In contrast, corticosteroids depress epithelial cell proliferation in fundic, antral, and duodenal mucosa of rats, and hydrocortisone predisposes to gastric ulcers. Proliferative rates are also modified by starvation, and pharmacologic and toxicologic doses of mineralocorticoids, glucocorticoids, and adrenocorticotropic hormone. Intestines Damage to small intestinal mucosa by toxicants results in a variety of changes depending on the degree and extent of injury. Damage to enterocytes without damage to underlying lamina propria or to the proliferative epithelial cell population lining the crypts will result in a temporary shortening of villi and decrease in height of remaining enterocytes as they flatten out to cover the denuded mucosal surface. As proliferative rate of crypt cells increases and the cell cycle time decreases, crypts will elongate as the number of newly formed epithelial cells increase. Complete cell differentiation and restoration of function generally takes longer than cell replacement since newly formed epithelial cells must leave the proliferative compartment and develop the specialized biochemical and morphologic features associated with absorptive enterocytes. Damage to the crypt cells by toxicants is a more serious matter, leading to "mucosal collapse. Death of crypt cells without underlying damage to lamina propria, in particular the vasculature, will eventually result in complete restitution of cryptal and villous epithelium, provided that complicating factors associated with loss of the mucosal barrier are minimized. Any one of these complicating factors, if unchecked, can lead to severe systemic consequences and defective restitution of the mucosal barrier. Damage to underlying vasculature, especially if thrombosis occurs, can exacerbate injury even further and lead to ulceration and hemorrhage as well. It is thought that maintenance of regional blood flow in areas of damage is essential for the minimization of ongoing damage and enhancement of repair and restitution in all sections of gut. By contrast, the colonic mucosa is covered by relatively flat mucus-secreting cells and crypts.
However acne 11 year old boy order 20 gm cleocin gel visa, both neutrophils and macrophages can stimulate as well as suppress the fibrotic response, and both contain collagenases. At autopsy, these may be found on visual examination but may be more evident on palpation. The presence of silica in dust inhaled by coal miners is the major cause of the pneumoconiosis. Ozone, endotoxin, and particulate matter induce parenchymal inflammation that can also be followed by fibrosis. Fibrosis is also an important component of the pneumoconioses, at least those caused following occupational exposure to mineral dusts such as asbestos, silica, and beryllium. Inhalation of dust containing crystalline-free silica leads to a progressive pulmonary disease characterized by extensive formation of granulomatous lesions and fibrosis throughout the lung parenchyma. Silicosis is mostly an occupational disease found in rock miners, sandblasters, stonecutters, and foundry workers, and generally presents decades after exposure. Contrary to many other dusts, which may remain within the phagolysosomes, silica has the potential to destroy lysosomal membranes, resulting in release of digestive enzymes and chemical mediators. These mediators, and other products of destroyed cells, stimulate the migration of additional macrophages to the lesion and may incite fibroblasts to proliferate and to synthesize increased amounts of collagen. The simple form of the disease (accumulation of pigment with macrophage infiltration) usually does not produce serious symptoms, although the inhaled coal dust may produce chronic bronchitis. Improved underground mining technology that allows miners to spend more time underground and newer mining methods that are thought to decrease the size of silica particles in dust may be increasing the amounts of coal dust and silica inhaled by miners, resulting in increased severity of disease at exposure concentrations (limits) that were formerly considered protective. Anthracosis, the simple accumulation of carbon pigment without a cellular response, is present in coal miners and urban dwellers. Inhalation of asbestos fibers in mining, milling, and manufacturing operations is another occupational health hazard that may lead to the development of chronic interstitial lung disease (asbestosis). Initially, inflammation develops at the respiratory bronchiolarÀalveolar duct junction, a preferred site for deposition of inhaled asbestos fibers. Deposition of iron on deposited fibers gives rise to asbestos bodies, a marker of asbestos exposure. The more important risk following exposure to asbestos is the development of cancer, either from the bronchial epithelium (bronchogenic carcinoma) or from the pleura (malignant mesothelioma). There is a synergistic interaction between asbestos and cigarette smoking in the development of bronchogenic carcinoma but not of malignant mesothelioma. Several metals, such as cadmium and beryllium, also may produce interstitial lung disease. Acute beryllium disease is characterized by acute interstitial pneumonia, and is usually associated with accidental exposure to high concentrations of beryllium. Although comparatively rare, it may be rapidly progressive and has been fatal in 10%À15% of cases. Chronic beryllium disease is caused by induction of cell-mediated immunity, and is characterized by multiple granulomas in the pulmonary parenchyma.
