Hypersensitivity pneumonitis: experimental production in calves with antigens of Micropolyspora faeni. (1/291)

Pneumonitis was induced in calves by exposure to aerosols of Micropolyspora faeni with or without prior sensitization of the animals by subcutaneous injection of antigen. The pneumonitis primarily involved centrolobular areas and was characterized by alveolar septal thickening and loss of air space by cellular infiltration. Vasculitis and focal haemorrhage occurred in certain individuals and haemoproteinaceous exudate appeared within septa and alveolar lumina. The pneumonitis was compared with human farmer's lung, pneumonitis of housed cattle and other experimental hypersensitivity pneumonitides.  (+info)

Mushroom worker's lung resulting from indoor cultivation of Pleurotus osteatus. (2/291)

Indoor cultivation of oyster mushroom Pleurotus osteatus lead to an outbreak of extrinsic allergic alveolitis in two workers. High titer of indirect fluorescent antibody and positive precipitins against basidiospores of P. osteatus were demonstrated in sera of the patients. Mushroom workers should protect themselves from the basidiospores, being aware of their pathogenicity.  (+info)

Compliance and stability of the bronchial wall in a model of allergen-induced lung inflammation. (3/291)

Airway wall remodeling in response to inflammation might alter load on airway smooth muscle and/or change airway wall stability. We therefore determined airway wall compliance and closing pressures in an animal model. Weanling pigs were sensitized to ovalbumin (OVA; ip and sc, n = 6) and were subsequently challenged three times with OVA aerosol. Control pigs received 0.9% NaCl (n = 4) in place of OVA aerosol. Bronchoconstriction in vivo was assessed from lung resistance and dynamic compliance. Semistatic airway compliance was recorded ex vivo in isolated segments of bronchus, after the final OVA aerosol or 0.9% NaCl challenge. Internally or externally applied pressure needed to close bronchial segments was determined in the absence or presence of carbachol (1 microM). Sensitized pig lungs exhibited immediate bronchoconstriction to OVA aerosol and also peribronchial accumulations of monocytes and granulocytes. Compliance was reduced in sensitized bronchi in vitro (P < 0.01), and closing pressures were increased (P < 0.05). In the presence of carbachol, closing pressures of control and sensitized bronchi were not different. We conclude that sensitization and/or inflammation increases airway load and airway stability.  (+info)

Regulatory effects of endogenous protease inhibitors in acute lung inflammatory injury. (4/291)

Inflammatory lung injury is probably regulated by the balance between proteases and protease inhibitors together with oxidants and antioxidants, and proinflammatory and anti-inflammatory cytokines. Rat tissue inhibitor of metalloprotease-2 (TIMP-2) and secreted leukoprotease inhibitor (SLPI) were cloned, expressed, and shown to be up-regulated at the levels of mRNA and protein during lung inflammation in rats induced by deposition of IgG immune complexes. Using immunoaffinity techniques, endogenous TIMP-2 in the inflamed lung was shown to exist as a complex with 72- and 92-kDa metalloproteinases (MMP-2 and MMP-9). In inflamed lung both TIMP-2 and SLPI appeared to exist as enzyme inhibitor complexes. Lung expression of both TIMP-2 and SLPI appeared to involve endothelial and epithelial cells as well as macrophages. To assess how these endogenous inhibitors might affect the lung inflammatory response, animals were treated with polyclonal rabbit Abs to rat TIMP-2 or SLPI. This intervention resulted in significant intensification of lung injury (as revealed by extravascular leak of albumin) and substantially increased neutrophil accumulation, as determined by cell content in bronchoalveolar lavage (BAL) fluids. These events were correlated with increased levels of C5a-related chemotactic activity in BAL fluids, while BAL levels of TNF-alpha and chemokines were not affected by treatment with anti-TIMP-2 or anti-SLPI. The data suggest that endogenous TIMP-2 and SLPI dynamically regulate the intensity of lung inflammatory injury, doing so at least in part by affecting the generation of the inflammatory mediator, C5a.  (+info)

Mycobacterium sp. as a possible cause of hypersensitivity pneumonitis in machine workers. (5/291)

Hypersensitivity pneumonitis (HP) in workers exposed to metal removal fluids (MRFs) is increasing. This study supports the hypothesis that aerosolized mycobacteria colonizing the MRFs likely cause the disease. Three case studies of HP outbreaks among metal workers showed potentially high exposures to a rare and newly proposed Mycobacterium species. Retrospective review of samples submitted to our laboratory showed an association between presence of mycobacteria and HP.  (+info)

Expression of mucosa-related integrin alphaEbeta7 on alveolar T cells in interstitial lung diseases. (6/291)

The expression of alphaEbeta7 integrin has been related to the selective retention of lymphocytes in mucosal tissues of gut, urogenital tract and lung. To identify potential disease-associated alphaEbeta7 expression patterns on cells accounting for lymphocytic alveolitis in interstitial lung disease (ILD), alphaE expression on CD4+ and CD8+ T cell subsets was evaluated by dual-colour flow cytometry in peripheral blood and bronchoalveolar lavage fluid (BALF) of patients with idiopathic pulmonary fibrosis (IPF; n = 18), hypersensitivity pneumonitis (HP; n = 20) and sarcoidosis (n = 44) in comparison with healthy controls (n = 15). In both healthy individuals and all patient groups the proportion of alphaE-bearing T cells in peripheral blood was < 2%, whereas the vast majority of alveolar CD8+ T cells consistently co-expressed alphaE. Absolute alveolar CD8+alphaE+ cell numbers/ml were up to 30-fold increased in HP patients. Proportions of alphaE-bearing CD4+ cells in BALF were significantly elevated in IPF (74.0 +/- 2.7%) and HP (70.0 +/- 2.4%) compared with normals (30.0 +/- 1.8%) (mean +/- s.e.m.; P < 0.01). In sarcoidosis, the alphaE expression on BALF CD4+ cells displayed subgroup dependency: proportions significantly lower than normal were noted in chest radiographic stage I (14.3 +/- 1.5%), but increased proportions in stages II (50.0 +/- 3.8%) and III (64.0 +/- 4.8%). Correlations between common markers of T cell activation or BALF transforming growth factor-beta (TGF-beta ) bioactivity and alphaE expression were not noted. We conclude that the vast majority of alveolar CD8+ T cells consistently express alphaEbeta7 and that distinct patterns of alphaEbeta7 expression on alveolar CD4+ lymphocytes in sarcoidosis are related to the diverse manifestations of the sarcoid inflammatory process in the lung.  (+info)

Viral infection modulates expression of hypersensitivity pneumonitis. (7/291)

Hypersensitivity pneumonitis (HP) is a granulomatous, inflammatory lung disease caused by inhalation of organic Ags, most commonly thermophilic actinomycetes that cause farmer's lung disease. The early response to Ag is an increase in neutrophils in the lung, whereas the late response is a typical Th1-type granulomatous disease. Many patients who develop disease report a recent viral respiratory infection. These studies were undertaken to determine whether viruses can augment the inflammatory responses in HP. C57BL/6 mice were exposed to the thermophilic bacteria Saccharopolyspora rectivirgula (SR) for 3 consecutive days per wk for 3 wk. Some mice were exposed to SR at 2 wk after infection with respiratory syncytial virus (RSV), whereas others were exposed to SR after exposure to saline alone or to heat-inactivated RSV. SR-treated mice developed a typical, early neutrophil response and a late granulomatous inflammatory response. Up-regulation of IFN-gamma and IL-2 gene expression was also found during the late response. These responses were augmented by recent RSV infection but not by heat-inactivated RSV. Mice with a previous RSV infection also had a greater early neutrophil response to SR, with increased macrophage inflammatory protein-2 (MIP-2, murine equivalent of IL-8) release in bronchoalveolar lavage fluid. These studies suggest that viral infection can augment both the early and late inflammatory responses in HP.  (+info)

Polarized type 1 cytokine profile in bronchoalveolar lavage T cells of patients with hypersensitivity pneumonitis. (8/291)

Hypersensitivity pneumonitis (HP) is characterized by an inflammatory lymphocytic alveolitis comprised of both CD8+ and CD4+ T cells. Animal models suggest that HP is facilitated by overproduction of IFN-gamma, and that IL-10 ameliorates severity of the disease, indicating a Th1-type response. To determine whether a Th1 phenotype in HP also exists clinically, bronchoalveolar lavage (BAL) and peripheral blood (PB) T cells were obtained from HP individuals and analyzed for Th1 vs Th2 cytokine profiles. It was determined that soluble OKT3-stimulated BAL T cells cocultured with alveolar macrophages produced more IFN-gamma and less IL-10 than PB T cells cocultured with monocytes, but no difference was observed in IL-4 production. The monocytic cells did not account for this difference, as CD80 and CD86 expressions were similar, and coculturing PB T cells with alveolar macrophages resulted in no difference in IFN-gamma production. Similarly, there was no difference in IL-12 production between stimulated BAL or PB T cells; however, addition of rIL-12 significantly increased production of IFN-gamma by BAL T cells, but not by PB T cells. This effect was due to a difference in IL-12R expression. High affinity IL-12R were only present in association with BAL T cells. These studies indicate that clinical HP is characterized by a predominance of IFN-gamma-producing T cells, perhaps resulting from a reduction in IL-10 production and an increase in high affinity IL-12R compared with blood T cells.  (+info)

Objective To estimate the reported incidence of occupational hypersensitivity pneumonitis (OHP) in the UK and to consider whether the pattern of attributed causation has changed over time. Methods All cases of OHP reported to the SWORD scheme between January 1996 and December 2015 were classified into 1 of 10 categories of the suspected agent. Cases were grouped into four 5-year time periods to examine any changing pattern in incidence or suspected causation. For each time period, the annual incidence was calculated using the estimated number of reported cases and the working population of the UK. Results Between 1996 and 2015, there were 202 actual cases of OHP reported to SWORD, equating to an estimated 818 cases, when adjusting for the sampling ratio. Over this period, the annual UK incidence was 1.4 per million workers. The mean (SD) age of reported cases was 52 (13) years, and cases were four-times more likely to be men than women. Over the study period, there was a fall in the proportion ...
This 49 year old patient was admitted with several weeks of worsening dyspnoea and dry cough. He had no history of previous respiratory illness. Further history revealed that several months prior he and his wife installed a hot tub in their bathroom. His HRCT chest showed widespread areas of ground glass opacity. Bronchoalveolar washings grew mycobacterium avium intracellulare (MAI). The diagnosis of hot tub lung was made and the patients symptoms rapidly resolved with corticosteroids. Interestingly, his wife was admitted with similar symptoms a few weeks later.. Hot tub lung is a hypersensitivity pneumonitis to MAI. MAI grows well in high water temperatures and is inhaled when the organism is aerosolised by the bubbles and steam generated from the hot tub. Poor hot tub maintenance with infrequent cleaning and changing of the filters contributes to the disease.. Hypersensitivity pneumonitis (extrinsic allergic alveolitis) is a hypersensitivity reaction to inhaled antigens. In the acute setting ...

Association between pulmonary disease and IgA nephropathy (IgAN) has been previously reported. However, no association has been reported between hypersensitivity pneumonitis (HP) and IgAN. Here, we report about a patient with no particular medical history, who experienced worsening dyspnoea in the course of 1 month, with ground-glass opacity on chest CT and no improvement after antibiotic therapy. The patient was diagnosed as having HP based on the history of antigen exposure, detection of Trichosporon asahii-specific antibodies and bronchoscopy findings. Concomitantly, findings of renal biopsy revealed the IgAN diagnosis. The patient underwent corticosteroid therapy, with good outcomes for both HP and IgAN. This is the first report in the literature to describe summer-type HP complicated with IgAN. ...

Significant advances have been noticed in the pathogenesis and the diagnosis of extrinsic allergic alveolitis during the last few years. Indeed the immune mechanism and the enabling conditions have been more precisely defined, the clinical stages and the diagnosis criterias clearly defined, new antigens incriminated and some etiological agents have been reclassified. The present pathogenic explanation insists on the type IV hypersensitivity reaction with sensitization of T lymphocytes, activation macrophages, the formation of IgG type antibodies and immune complexes, activation of complement and secretion of cytokines. The involvement of certain HLA classes (HLA2, DR3, DRB1, DQB1), interaction of genetics and environments factors, the role of infections agents and smoking have been demonstrated in several studies. The development of news clinical and biological diagnosis criteria have led the discovery of new extrinsic allergic alveolitis in the work places, a better knowledge of the prognostic elements
This patients clinical history and pathology were consistent with subacute hypersensitivity pneumonitis which typically presents with the gradual onset of dyspnoea, cough, and weight loss.1 The chest radiograph may be normal or may have reticulonodular and ground glass infiltrates. The HRCT scan usually contains small nodules with areas of ground glass opacities.5 Air trapping may also be present. The patients HRCT scan was highly suggestive of hypersensitivity pneumonitis, and the pathology was characteristic with findings of interstitial inflammation, bronchiolitis, and non-necrotising granulomas.6 The distribution and appearance of the granulomas were sufficient to distinguish the disease from sarcoidosis and mycobacterial or fungal disease.. BAL fluid lymphocyte subsets can be helpful in diagnosing hypersensitivity pneumonitis in the non-immunocompromised patient, but the interpretation of BAL lymphocyte subsets in the HIV infected patient is less straightforward. Studies have shown a BAL ...

Hypersensitivity pneumonitis (HP), also referred to as extrinsic allergic alveolitis, is a pulmonary disease that occurs due to inhalational exposure to a variety of antigens leading to an inflammatory response of the alveoli and small airways. Systemic manifestations such as fever and fatigue can accompany respiratory symptoms. Although sensitization to an inhaled antigen as manifested by specific circulating IgG antibodies is necessary for the development of HP, sensitization alone is not sufficient as a defining characteristic, because many sensitized individuals do not develop HP. The incidence and prevalence of HP are variable, depending on geography, occupation, avocation, and environment of the cohort being studied. As yet unexplained is the decreased risk of developing HP in smokers. ...
Mayfair Veterinary Clinic, Hobart Allergic alveolitis is a respiratory disease of humans. It is the result of a hypersensitivity to avian antigens. This includes serum, feathers, feather dust, and faecal material. The condition is also called hypersensitivity pneumonitis, bronchiolitis, allergic interstitial pneumonitis, parakeet dander pneumoconiasis, acute psittacokeratopneumoconiosis, and pigeon lung disease. There are acute, subacute, and chronic forms of this disease. The acute form occurs 4 to 8 hours after exposure to a heavy load of avian antigen, such as cleaning out a chook house. Coughing, difficulty breathing, fever, and chills occur. There are rattling sounds when breathing in, and an increase in white blood cells, especially eosinophils. X-rays of the lungs show changes consistent with allergic response. Attacks subside within 24 hours without treatment. The condition is confirmed by the history of exposure and by a skin test. The subacute form results from long-term exposure to a ...
A 41-year-old automobile paint sprayer showed the clinical features of hypersensitivity pneumonitis 1 week after he had begun to work with paint materials containing toluene diisocyanate. His symptoms began 6 to 8 hours after exposure to the agent and spontaneously disappeared by the next morning. He had diffuse, fine reticulonodular shadows on a chest roentgenogram and a restrictive impairment of pulmonary function.

Hypersensitivity pneumonitis (HP), also referred to as extrinsic allergic alveolitis (EAA), is an inflammatory lung disease resulting from the inhalation and subsequent sensitization to a wide variety of inhaled organic dusts.1-5 HP is not mediated by IgE. It is associated with progressive pulmonary disability, irreversible lung damage, and mortality in some occupational settings.1-5 Patients often present with intermittent chills, fever, cough, and shortness of breath that begin four to eight hours after exposure to the offending dust. Aspergillus mold can be found in soil, foods, fresh water, and other natural sources including compost, barley, tobacco, and Esparto grass dust (stucco).1,3,5 These organisms grow well in decaying organic material at temperatures often attained during decomposition.5Aspergillus mold can also grow on ceiling and walls where water damage has occurred.6. No single laboratory test is diagnostic for hypersensitivity pneumonitis.1-5 Diagnosis is based on a complete ...
Can methods less invasive than SLB, including BAL and TBB, be useful in the diagnosis of IPF? The short answer is no. BAL cellular analysis has been used for many years in the diagnosis of several ILDs. When evaluating individuals with suspected IPF, BAL is useful in excluding other conditions, especially chronic hypersensitivity pneumonitis, for which a diagnosis is suggested by a lymphocytosis ,40% [2]. A recent publication of retrospective data reported that 8% of individuals with a HRCT UIP pattern may have BAL features that would point to an alternative diagnosis to IPF [2, 15]. The 2011 guidelines recommend, however, that BAL cellular analysis should not be performed in the diagnostic evaluation of IPF in the majority of individuals, but may be appropriate for a minority. The evidence regarding whether or not BAL adds significantly improved diagnostic specificity is presently unclear [2].. TBB has been shown to be useful in the evaluation of conditions that are predominantly bronchocentric ...
Norman Woodward, 75, a poultry farmer from Sandbach, Cheshire, United Kingdom, died from lung disease after a lifetime exposure to chicken waste.. Coroner, Dr. Geoff Roberts, said Normans illness was linked to his time working with poultry.. Norman became ill and increasingly short of breath after his retirement aged 64.. According to Dr. Roberts, Norman exposure to a number of antigens in poultry over the years resulted to develop him the condition of allergic alveolitis. After continued exposure, he developed the lung disease associated with his occupation, and theres no doubt that these led him to his death, said Dr. Roberts.. His widow Heather told during the court hearing at Crewe Law Courts, Cheshire, that she remember once Norman came covered hand to foot in chicken muck.. According to her, on occasions the silage tower would get blocked and he would have to go and find where the blockage was. All he would wear was his own cap, his boiler suit and his rubber boots..

Symptoms of the following disorders can be similar to extrinsic allergic alveolitis. Comparisons may be useful for a differential diagnosis:. Asthma is characterized by breathing difficulty caused by a wide variety of factors, often associated with allergies. In general, the air passages become narrowed and may return to normal spontaneously, although treatment is often necessary. Long-term cases can diminish in severity, depending on the underlying cause and method of treatment. There is no known cure, but attacks may be controlled to various degrees.. Desquamative interstitial pneumonia is a chronic form of pneumonia. The exact cause of this disorder is not known. Symptoms are caused by shedding of large alveolar cells (desquamation) in the lungs and thickening of the walls of the air passages. This disorder is characterized by breathing difficulty and accompanied by a harsh cough that does not seem to clear the obstruction.. Fibrosing alveolitis, also known as acute pulmonary alveolitis, is ...
Alveolitis can refer to two inflammatory conditions. It can refer to inflammation of the alveoli in the lungs, or the dental alveolus in the jaw. Extrinsic allergic alveolitis is a lung disorder resulting from repeated inhalation of organic dust, usually in a specific occupational setting. In the acute form, respiratory symptoms and fever begin several hours after exposure to the dust. The chronic form is characterized by gradual changes in the lung tissue associated with several years of exposure to the irritant. ...

Hypersensitivity pneumonitis. This is an allergic lung disease caused by a lung inflammation that happens from breathing in many different substances including fungus spores, bacteria, animal or plant protein, or specific chemicals. They can come from moldy hay, bird droppings, and other organic dusts. The disease causes inflamed air sacs in the lungs, and leads to fibrous scar tissue in the lungs and trouble breathing. There are variations of this disease depending on the job. They include cork workers lung, farmers lung, and mushroom workers lung ...

Occupational asthma is an occupational lung disease and a type of asthma. Like other types of asthma, it is characterized by airway inflammation, reversible airways obstruction, and bronchospasm, but it is caused by something in the workplace environment. Symptoms include shortness of breath, tightness of the chest, nasal irritation, coughing and wheezing. The first person to use it in reference to a medical condition was Hippocrates, and he believed that tailors, anglers and metalworkers were more likely to be affected by the disease. Although much research has been done since, the inflammatory component of asthma was recognized only in the 1960s. Hypersensitivity pneumonitis is a related condition, with many occupational examples (e.g. flock workers lung, farmers lung, and indium lung). However, although overlapping in many cases, hypersensitivity pneumonitis may be distinguished from occupational asthma in that it isnt restricted to only occupational exposure, and involves type III ...
Environmental opportunistic mycobacteria, including Mycobacterium avium, M. terrae, and the new species M. immunogenum, have been implicated in outbreaks of hypersensitivity pneumonitis or respiratory problems in a wide variety of settings. One common feature of the outbreaks has been exposure to aerosols. Aerosols have been generated from metalworking fluid during machining and grinding operations as well as from indoor swimming pools, hot tubs, and water-damaged buildings. Environmental opportunistic mycobacteria are present in drinking water, resistant to disinfection, able to provoke inflammatory reactions, and readily aerosolized. In all outbreaks, the water sources of the aerosols were disinfected. Disinfection may select for the predominance and growth of mycobacteria. Therefore, mycobacteria may be responsible, in part, for many outbreaks of hypersensitivity pneumonitis and other respiratory problems in the workplace and home ...

repeated with more modern scanners or with digital CT analysis techniques, which might yield greater sensitivity.. Correlation with Physiology. The extent of decreased attenuation on CT correlates with physiologic evidence of air trapping (elevated residual volume), while the extent of ground-glass and reticular abnormalities correlated independently with evidence of restrictive pulmonary function (45, 46). Centrilobular nodules do not correlate with pulmonary function abnormalities (30).. Correlation with Pathology There is sparse information regarding the relationship between imaging features of HP and their pathologic correlates. Centrilobular nodules probably represent the peribronchiolar lymphocytic infiltration frequently seen on histology in HP. Ground glass abnormality is a nonspecific finding that may represent inflammatory infiltration or fibrosis (47, 48). Air trapping does not have a proven histologic correlate, but seems most likely to be due to bronchiolar obstruction (29, 49). ...
It involves the lung parenchyma and specifically the alveoli, terminal bronchioli, and alveolar interstitium. Repeated exposure to particles sufficiently small (diameter < 5 μm) to reach the alveoli and to trigger an immune response is necessary. Primarily an occupation-linked disorder, the most at risk professional categories are workers in environments or settings contaminated by organic dust of various origin, mostly farmers or breeders. The syndrome is greatly variable in symptoms severity, clinical presentation, and prognosis, depending on the nature of causative agent, the duration of exposure, the host factors, and the characteristics of the antigen. In most cases, it can be reversed, in the early stages, by promptly identifying and removing the causative agent(s ...

Bird fanciers lung is a type of hypersensitivity pneumonitis caused by bird droppings. The lungs become inflamed with granuloma formation. Bird fanciers lung (BFL), also called bird-breeders lung and pigeon-breeders lung, is a subset of hypersensitivity pneumonitis (HP). This disease is caused by the exposure to avian proteins present in the dry dust of the droppings and sometimes in the feathers of a variety of birds. Birds such as pigeons, parakeets, cockatiels, shell parakeets (budgerigars), parrots, turtle doves, turkeys and chickens have been implicated. People who work with birds or own many birds are at risk. Bird hobbyists and pet store workers may also be at risk. This disease is an inflammation of the alveoli in the lungs. Initial symptoms are breathlessness especially after sudden exertion or when exposed to temperature change and can be very similar to asthma, hyperventilation syndrome or pulmonary embolism. One of the defining characteristics of bird fanciers lung is that many ...
Hypersensitivity pneumonitis may also be caused by fungi or bacteria in humidifiers, heating systems, and air conditioners found in homes and offices. Exposure to certain chemicals, such as isocyanates or acid anhydrides, can also lead to hypersensitivity pneumonitis.. Examples of hypersensitivity pneumonitis include:. Bird fanciers lung: This is the most common type of hypersensitivity pneumonitis. It is caused by repeated or intense exposure to proteins found in the feathers or droppings of many species of birds.. Farmers lung: This type of hypersensitivity pneumonitis is caused by exposure to dust from moldy hay, straw, and grain. ...
Initial symptoms of hypersensitivity pneumonitis are similar to the flu, but it can take several months to a number of years to develop allergy to the dust. Certain occupations may increase your risk of developing hypersensitivity pneumonitis.

Now that a potential buyer has established they can legally buy spores, which ones do they choose to purchase? There are several common kinds of psychedelic mushroom spores that buyers can find for sale. Magic mushrooms tend to have different strains, which are named typically after the location in which they are found, or the physical characteristics that are observed. Some are more potent than others in the amount of psilocybin or psilocin content that is contained within them, some will be larger, or smaller, and some may have different coloration, or become mutated like in the case of Penis Envy. The majority psilocybin mushrooms are either tropical or subtropical, and prefer composted manure or dung in areas of land that are well fertilized to thrive. The not so common psilocybin mushroom varieties are commonly called exotic, although the majority of psilocybin genera spores are technically exotic if you live in the United States of America.

The following abstract describes a publication that is intended for print distribution or as a downloadable PDF. Please see links to the PDF file and ordering information on this page.. Cultivating shiitake mushrooms represents an opportunity to utilize healthy low-grade and small-diameter trees thinned from woodlots as well as healthy branch-wood cut from the tops of harvested saw-timber trees. When the mushrooms are collected and marketed, the result is a relatively short-term payback for long-term management of wooded areas.. The cultivation of shiitake mushrooms on solid wood requires a significant amount of shade and wind protection, but not a significant amount of acreage. Therefore it is an excellent opportunity for landowners with smaller acreages to utilize forested or shaded areas. Shiitake producers can often obtain wood for cultivation from land management agencies or private landowners. In addition to making productive use of woodlots and forested acres, logs that have been used for ...

Eritadenine is a substance that might help the Western world to overcome one of the biggest cause of death, cardiovascular disease, by lowering the levels of cholesterol in blood by an accelerated excretion of ingested cholesterol. The aim of this thesis work was to elucidate if enzymatic pre-treatment of shiitake mushrooms increases the yield of the extraction process of the valuable substance eritadenine by increasing the degradation of the fungal cell walls. The enzymes used in this study, had glucanase and chitinase activity and was a gift from Novozymes, Denmark. The extraction process involves treatment with methanol followed by extraction with ether and finally ion exchange in order to obtain a sample as pure as possible for analysis. In contrast to previously used methods the mushrooms are treated with enzymes before the methanol extraction, which hopefully facilitate the degradation of the cell walls. The results obtained with enzymatic pre-treatment showed a deterioration compared to ...
