Bronchioles: The small airways branching off the TERTIARY BRONCHI. Terminal bronchioles lead into several orders of respiratory bronchioles which in turn lead into alveolar ducts and then into PULMONARY ALVEOLI.Bronchi: The larger air passages of the lungs arising from the terminal bifurcation of the TRACHEA. They include the largest two primary bronchi which branch out into secondary bronchi, and tertiary bronchi which extend into BRONCHIOLES and PULMONARY ALVEOLI.Lung: Either of the pair of organs occupying the cavity of the thorax that effect the aeration of the blood.Uteroglobin: A steroid-inducible protein that was originally identified in uterine fluid.

This is usually due to destruction of the alveolar wall. Pulmonary emphysema can be classified by the location and distribution of the lesions.Muscle, Smooth: Unstriated and unstriped muscle, one of the muscles of the internal organs, blood vessels, hair follicles, etc. Contractile elements are elongated, usually spindle-shaped cells with centrally located nuclei. Smooth muscle fibers are bound together into sheets or bundles by reticular fibers and frequently elastic nets are also abundant. (From Stedman, 25th ed)Bronchiolitis Obliterans: Inflammation of the BRONCHIOLES leading to an obstructive lung disease. Bronchioles are characterized by fibrous granulation tissue with bronchial exudates in the lumens. Clinical features include a nonproductive cough and DYSPNEA.Cryptogenic Organizing Pneumonia: An interstitial lung disease of unknown etiology, occurring between 21-80 years of age. It is characterized by a dramatic onset of a "pneumonia-like" illness with cough, fever, malaise, fatigue, and weight loss. Pathological features include prominent interstitial inflammation without collagen fibrosis, diffuse fibroblastic foci, and no microscopic honeycomb change. There is excessive proliferation of granulation tissue within small airways and alveolar ducts.Epithelial Cells: Cells that line the inner and outer surfaces of the body by forming cellular layers (EPITHELIUM) or masses. Epithelial cells lining the SKIN; the MOUTH; the NOSE; and the ANAL CANAL derive from ectoderm; those lining the RESPIRATORY SYSTEM and the DIGESTIVE SYSTEM derive from endoderm; others (CARDIOVASCULAR SYSTEM and LYMPHATIC SYSTEM) derive from mesoderm. Epithelial cells can be classified mainly by cell shape and function into squamous, glandular and transitional epithelial cells.Lung Volume Measurements: Measurement of the amount of air that the lungs may contain at various points in the respiratory cycle.Histological Techniques: Methods of preparing tissue for examination and study of the origin, structure, function, or pathology.Immunohistochemistry: Histochemical localization of immunoreactive substances using labeled antibodies as reagents.Airway Obstruction: Any hindrance to the passage of air into and out of the lungs.Bronchoalveolar Lavage Fluid: Washing liquid obtained from irrigation of the lung, including the BRONCHI and the PULMONARY ALVEOLI. It is generally used to assess biochemical, inflammatory, or infection status of the lung.Intermediate-Conductance Calcium-Activated Potassium Channels: A major class of calcium-activated potassium channels that were originally discovered in ERYTHROCYTES. They are found primarily in non-excitable CELLS and set up electrical gradients for PASSIVE ION TRANSPORT.Aerosols: Colloids with a gaseous dispersing phase and either liquid (fog) or solid (smoke) dispersed phase; used in fumigation or in inhalation therapy; may contain propellant agents.Lung Diseases: Pathological processes involving any part of the LUNG.Tissue Inhibitor of Metalloproteinase-3: A member of the family of tissue inhibitor of metalloproteinases. Mutations of the gene for TIMP3 PROTEIN causes Sorsby fundus dystrophy.Nitrogen Dioxide: Nitrogen oxide (NO2). A highly poisonous gas. Exposure produces inflammation of lungs that may only cause slight pain or pass unnoticed, but resulting edema several days later may cause death. (From Merck, 11th ed) It is a major atmospheric pollutant that is able to absorb UV light that does not reach the earth's surface.1-(5-Isoquinolinesulfonyl)-2-Methylpiperazine: A specific protein kinase C inhibitor, which inhibits superoxide release from human neutrophils (PMN) stimulated with phorbol myristate acetate or synthetic diacylglycerol.Inhalation Exposure: The exposure to potentially harmful chemical, physical, or biological agents by inhaling them.MaleimidesEndothelium: A layer of epithelium that lines the heart, blood vessels (ENDOTHELIUM, VASCULAR), lymph vessels (ENDOTHELIUM, LYMPHATIC), and the serous cavities of the body.Cilia: Populations of thin, motile processes found covering the surface of ciliates (CILIOPHORA) or the free surface of the cells making up ciliated EPITHELIUM. Each cilium arises from a basic granule in the superficial layer of CYTOPLASM. The movement of cilia propels ciliates through the liquid in which they live. The movement of cilia on a ciliated epithelium serves to propel a surface layer of mucus or fluid. (King & Stansfield, A Dictionary of Genetics, 4th ed)Pneumonia: Infection of the lung often accompanied by inflammation.Indoles: Benzopyrroles with the nitrogen at the number one carbon adjacent to the benzyl portion, in contrast to ISOINDOLES which have the nitrogen away from the six-membered ring.Pulmonary Fibrosis: A process in which normal lung tissues are progressively replaced by FIBROBLASTS and COLLAGEN causing an irreversible loss of the ability to transfer oxygen into the bloodstream via PULMONARY ALVEOLI. Patients show progressive DYSPNEA finally resulting in death.Microscopy, Electron: Microscopy using an electron beam, instead of light, to visualize the sample, thereby allowing much greater magnification. The interactions of ELECTRONS with specimens are used to provide information about the fine structure of that specimen. In TRANSMISSION ELECTRON MICROSCOPY the reactions of the electrons that are transmitted through the specimen are imaged. In SCANNING ELECTRON MICROSCOPY an electron beam falls at a non-normal angle on the specimen and the image is derived from the reactions occurring above the plane of the specimen.Phorbol 12,13-Dibutyrate: A phorbol ester found in CROTON OIL which, in addition to being a potent skin tumor promoter, is also an effective activator of calcium-activated, phospholipid-dependent protein kinase (protein kinase C). Due to its activation of this enzyme, phorbol 12,13-dibutyrate profoundly affects many different biological systems.Serotonin: A biochemical messenger and regulator, synthesized from the essential amino acid L-TRYPTOPHAN. In humans it is found primarily in the central nervous system, gastrointestinal tract, and blood platelets. Serotonin mediates several important physiological functions including neurotransmission, gastrointestinal motility, hemostasis, and cardiovascular integrity. Multiple receptor families (RECEPTORS, SEROTONIN) explain the broad physiological actions and distribution of this biochemical mediator.Isoquinolines: A group of compounds with the heterocyclic ring structure of benzo(c)pyridine. The ring structure is characteristic of the group of opium alkaloids such as papaverine. (From Stedman, 25th ed)Administration, Inhalation: The administration of drugs by the respiratory route.

Albuterol is prepared as a racemic mixture of R(-) and S(+) stereoisomers. The stereospecific preparation of R(-) isomer of albuterol is referred to as levalbuterol.Rats, Wistar: A strain of albino rat developed at the Wistar Institute that has spread widely at other institutions. This has markedly diluted the original strain.Microscopy, Electron, Scanning: Microscopy in which the object is examined directly by an electron beam scanning the specimen point-by-point. The image is constructed by detecting the products of specimen interactions that are projected above the plane of the sample, such as backscattered electrons. Although SCANNING TRANSMISSION ELECTRON MICROSCOPY also scans the specimen point by point with the electron beam, the image is constructed by detecting the electrons, or their interaction products that are transmitted through the sample plane, so that is a form of TRANSMISSION ELECTRON MICROSCOPY.In Situ Hybridization: A technique that localizes specific nucleic acid sequences within intact chromosomes, eukaryotic cells, or bacterial cells through the use of specific nucleic acid-labeled probes.Lung Neoplasms: Tumors or cancer of the LUNG.Animals, Newborn: Refers to animals in the period of time just after birth.Rats, Inbred F344Carbachol: A slowly hydrolyzed CHOLINERGIC AGONIST that acts at both MUSCARINIC RECEPTORS and NICOTINIC RECEPTORS.Macaca mulatta: A species of the genus MACACA inhabiting India, China, and other parts of Asia. The species is used extensively in biomedical research and adapts very well to living with humans.Muscle Contraction: A process leading to shortening and/or development of tension in muscle tissue. Muscle contraction occurs by a sliding filament mechanism whereby actin filaments slide inward among the myosin filaments.Acetylcholine: A neurotransmitter found at neuromuscular junctions, autonomic ganglia, parasympathetic effector junctions, a subset of sympathetic effector junctions, and at many sites in the central nervous system.Dogs: The domestic dog, Canis familiaris, comprising about 400 breeds, of the carnivore family CANIDAE. They are worldwide in distribution and live in association with people. (Walker's Mammals of the World, 5th ed, p1065)Mice, Inbred C57BLSheep: Any of the ruminant mammals with curved horns in the genus Ovis, family Bovidae. They possess lachrymal grooves and interdigital glands, which are absent in GOATS.Disease Models, Animal: Naturally occurring or experimentally induced animal diseases with pathological processes sufficiently similar to those of human diseases. They are used as study models for human diseases.RNA, Messenger: RNA sequences that serve as templates for protein synthesis. Bacterial mRNAs are generally primary transcripts in that they do not require post-transcriptional processing. Eukaryotic mRNA is synthesized in the nucleus and must be exported to the cytoplasm for translation. Most eukaryotic mRNAs have a sequence of polyadenylic acid at the 3' end, referred to as the poly(A) tail. The function of this tail is not known for certain, but it may play a role in the export of mature mRNA from the nucleus as well as in helping stabilize some mRNA molecules by retarding their degradation in the cytoplasm.Neutrophils: Granular leukocytes having a nucleus with three to five lobes connected by slender threads of chromatin, and cytoplasm containing fine inconspicuous granules and stainable by neutral dyes.

Type IV collagen alpha chains of the basement membrane in the rat bronchioalveolar transitional segment. (7/99)

In the present study, we have analyzed the alpha(IV) chain distribution in the subepithelial basement membrane (BM) of the rat pulmonary airway from the bronchi to alveoli. We have furthermore analyzed the alpha(IV) chain distribution in the subepithelial BM of the bronchioalveolar duct junction (BADJ) using alpha(IV) chain specific monoclonal antibodies. Our results show that the BM of the bronchial and bronchiolar epithelium contains [alpha1(IV)]2alpha2(IV) and [alpha5(IV)]2alpha6(IV) molecules and confirmed that the alveolar BM consists of [alpha1(IV)]2alpha2(IV) and alpha3(IV) alpha4(IV)alpha5(IV) molecules. There are also small regions in BADJ consisting of only [alpha1(IV)]2alpha2(IV) molecules without alpha3(IV)alpha4(IV)alpha5(IV) and [alpha5(IV)]2alpha6(IV) molecules. Moreover, the bronchioalveolar stem cells (BASCs)-primordial cells for bronchiolar Clara cells and alveolar type II (AT2) cells - lie adjacent to such small regions. These findings suggest that [alpha1(IV)]2 alpha2(IV) may be important for the BASCs to self-renew or to self-maintain themselves and that microenvironments produced by alpha(IV) chains may be important for cell differentiation.  (+info)

Club cell secretory protein (CC-16) is a sensitive biomarker of airways epithelium integrity. It has gained interest as a biological marker in chronic lung diseases because of its presumed relationship to inflammation. Little is known about the association between CC-16 serum level and asthma, lung function and airway responsiveness (AR). Serum CC-16 level was determined by latex immunoassay in 1298 participants from the French Epidemiological case-control and family-based study on Genetics and Environment of Asthma (EGEA) (mean age 43 years; 49% men, 38% with asthma). Pre-bronchodilator lung function (forced expiratory volume in 1 s (FEV1 ), forced vital capacity (FVC) and FEV1 /FVC) and degree of AR, expressed as a function of the dose-response slope to methacholine test were measured. Standardized residuals CC-16 z-scores were obtained by regressing CC-16 level on the glomerular filtration rate. CC-16 z-scores were correlated with asthma, lung function and AR in participants with and without asthma.
Background Club Cell protein (CC)16 correlates with lung injury and respiratory complications, which are in part triggered by polymorphonuclear leukocytes (PMNL) in severely traumatized patients (TP)....

Clara cells are non-mucous and non-ciliated secretory cells found in the primary bronchioles of the lungs, and were originally described by their namesake, Max Clara in 1937.. Clara cells are dome-shaped and have short microvilli. One of the main functions of Clara cells is to protect the bronchiolar epithelium. They do this by secreting a small variety of products, including Clara cell secretory protein (CCSP) and a component of the lung surfactant. They are also responsible for detoxifying harmful substances inhaled into the lungs. Clara cells accomplish this with cytochrome P450 enzymes found in their smooth endoplasmic reticulum. Clara cells also multiply and differentiate into ciliated cells to regenerate the bronchiolar epithelium.. CC10 (Clara cell secretory protein) ...
article{2003590, abstract = {During lung development, parabronchial SMC (PSMC) progenitors in the distal mesenchyme secrete fibroblast growth factor 10 (Fgf10), which acts on distal epithelial progenitors to promote their proliferation. beta-catenin signaling within PSMC progenitors is essential for their maintenance, proliferation, and expression of Fgf10. Here, we report that this Wnt/Fgf10 embryonic signaling cascade is reactivated in mature PSMCs after naphthalene-induced injury to airway epithelium. Furthermore, we found that this paracrine Fgf10 action was essential for activating surviving variant Clara cells (the cells in the airway epithelium from which replacement epithelial cells originate) located at the bronchoalveolar duct junctions and adjacent to neuroendocrine bodies. After naphthalene injury, PSMCs secreted Fgf10 to activate Notch signaling and induce Snail expression in surviving variant Clara cells, which subsequently underwent a transient epithelial to mesenchymal transition ...
The principle function of the lung is to provide oxygen to the blood and in exchange rid the blood from carbon dioxide. Inhaled air passes through the trachea that branch into two bronchi, each supplying one of the two lobes of lung. In the lung, each bronchus branches into narrower bronchi that eventually terminate in bronchioles. The wall of bronchioles consist of ciliated cuboidal epithelium and a thin layer of smooth muscle. As opposed to upper parts of the respiratory tract, it lacks hyaline cartilage. The main cell types of the bronchioles are similar to the ones in the bronchi namely, basal cells, neuroendocrine cells, ciliated cells, serous cells, Clara cells and goblet cells. Goblet and ciliated cells decrease in number as one approaches the terminal bronchioles, whereas the number of Clara cells increases proportionally. The Clara cells have a secretory function and represent the main progenitor cell after bronchiolar injury. They are columnar to cuboidal in shape and project above the ...

GPRC5A is a G-protein coupled receptor expressed in lung tissue but repressed in most human lung cancers. Studies in Gprc5a-/- mice have established its role as a tumor suppressor function in this setting, but its the basis for its role have been obscure. Here we report that GPRC5A functions as a negative modulator of EGFR signaling. Mouse tracheal epithelial cells (MTEC) from Gprc5a-/- mice exhibited a relative increase in EGFR and downstream STAT3 signaling, whereas GPRC5A expression inhibited EGFR and STAT3 signaling. GPRC5A physically interacted with EGFR through its transmembrane domain, which was required for its EGRF inhibitory activity. Gprc5a-/- MTEC were much more susceptible to EGFR inhibitors than wile-type MTEC, suggesting their dependence on EGFR signaling for proliferation and survival. Dysregulated EGFR and STAT3 were identified in the normal epithelia of small and terminal bronchioles as well as tumors of Gprc5a-/- mouse lungs. Moreover, in these lungs EGFR inhibitor treatment ...
The human body requires energy to maintain life. Each organ is made up of millions of cells that perform various life support functions. All of these organs and cells have the same basic requirements. They need delivery of oxygen and fuel (such as glucose) in order to produce energy. And they need removal of unwanted energy byproducts like carbon dioxide. It is the team effort provided by the heart and lungs that provides this service to the cells. The lungs provide oxygenation of the blood and the heart pumps that oxygenated blood along with glucose and other nutrients to the cells. The heart then transports the carbon dioxide back from the cells to the lungs where it is disposed. [pic1]This cycle begins when the diaphragm contracts and generates a negative pressure inside the chest cavity that causes the lungs to expand thus drawing in outside air. This air traverses a system of tubes that begins with the trachea and ends where the terminal bronchiole connects to the alveolus or air sac. The ...
Tree-in-bud appearance represents dilated and fluid-filled (i.e. pus, mucus, or inflammatory exudate) centrilobular bronchioles. Abnormal tree-in-bud bronchioles can be distinguished from normal centrilobular bronchioles by their more irregular appearance, lack of tapering or knobby/bulbous appearance at the tip of their branches. The tree-in-bud distribution is often patch throughout the lung. ...
Covidien (NYSE:COV [1]) and Philips [2] (NYSE:PHG [3]) are launching another pulse oximetry product as part of a long-running partnership. Mansfield, Mass.-based Covidien said it will provide its Nellcor SpO2 pulse oximetry technology for use with the Philips IntelliVue patient monitoring platform in North America, Europe and elsewhere. The partnership between 2 of the largest companies in the medical device space dates back to 2009, according to a Covidien spokeswoman. The company does not break out how much revenue it derives from the distribution deal, as the Respiratory & Monitoring Solutions division is 1 of 5 operating units in the companys medical device segment, which brought in over $2 billion in sales [4] during the 3 months ended March 30. Covidien recently bolstered the respiratory unit with a $300 million acquisition [5] of Oridion Systems in April. That deal is expected to close this quarter.. "Because Nellcor OxiMax technology relies on cardiac signals, it mitigates signal ...
Here is another miracle system. Air enters your nose and passes down to that same pharynx again. But this time, the swallow mechanism is not in operation, so the air goes directly downward into the larynx, past your voice box, and into the trachea, which then divides into the two bronchi, which then lead through the bronchioles into tiny air sacs called atria. Think of two trees with their branches continually rebranching until finally they end-in grapes! That is the appearance of the bronchi, bronchioles, and atria. Tiny projections, called alveoli, protrude outward from each grape-like atrium into the lung. It all does look very much like a bunch of grapes! The plan is to exchange oxygen for carbon dioxide-as much as possible and as quickly as possible. There are over 400 million alveoli; each one is closely connected with blood and lymph vessels, nerves, and connective tissue.. That is what, on the inside, your lungs look like; From the outside, the lungs appear to be two cone-shaped organs, ...

The lung is the main organ in the respiratory system and doesnt develop till about week 4 in the embryo. This stage of development is known as the Embryonic stage that covers the period of week 4-5 of the developing embryo. In this stage the 2 lung buds would have formed and lung lobes and the bronchopulmonary segments. The stem diverticulum will have differentiated into trachea and larynx. The Pseudoglandular stage is the period from 6 weeks to 16 weeks in the growing fetus. The events that occur in this stage include the formation of extensive airway branching of about 14 or more generations of branching resulting in terminal bronchioles. The conducting epithelium tubes are formed and are surrounded by thick mesenchyme. At 2 months all of the segmental bronchi would have formed. The distal structures at this stage are lined with cuboidal epithelium. The next stage is the Canalicular stage, from the period of week 16 to 25. The terminal bronchioles divide into two or more respiratory ...
Diffuse panbronchiolitis (DPB) is an inflammatory lung disease of unknown cause. It is a severe, progressive form of bronchiolitis, an inflammatory condition of the bronchioles (small air passages in the lungs). The term diffuse signifies that lesions appear throughout both lungs, while panbronchiolitis refers to inflammation found in all layers of the respiratory bronchioles (those involved in gas exchange). DPB causes severe inflammation and nodule-like lesions of terminal bronchioles, chronic sinusitis, and intense coughing with large amounts of sputum production. The disease is believed to occur when there is susceptibility, or a lack of immune system resistance, to DPB-causing bacteria or viruses, caused by several genes that are found predominantly in individuals of East Asian descent. The highest incidence occurs among Japanese people, followed by Koreans. DPB occurs more often in males, and usually begins around age 40. It was recognized as a distinct new disease in the early 1960s, and ...
In the lungs, air is diverted into smaller and smaller passages, or bronchi. Air enters the lungs through the two primary (main) bronchi (singular: bronchus). Each bronchus divides into secondary bronchi, then into tertiary bronchi, which in turn divide, creating smaller and smaller diameter bronchioles as they split and spread through the lung. Like the trachea, the bronchi are made of cartilage and smooth muscle. At the bronchioles, the cartilage is replaced with elastic fibers. Bronchi are innervated by nerves of both the parasympathetic and sympathetic nervous systems that control muscle contraction (parasympathetic) or relaxation (sympathetic) in the bronchi and bronchioles, depending on the nervous systems cues. In humans, bronchioles with a diameter smaller than 0.5 mm are the respiratory bronchioles. They lack cartilage and therefore rely on inhaled air to support their shape. As the passageways decrease in diameter, the relative amount of smooth muscle increases.. The terminal ...

Humidifier disinfectant (HD) damage was terrible chemical damage caused by household goods that happened in only South Korea, but still very little is known in HD damage. Up to now, previous research tried to focus on interstitial fibrosis on terminal bronchioles and alveoli because it is a specific finding, compared with other diseases. To figure out whole effects from HDs, much epidemiologic and toxicologic research is underway. HDs were shown to give rise to typical toxicologic effects on various target organs, such as skin, conjunctiva, naval mucosa, bronchial mucosa, alveoli and so on, which shared common toxicological responses. On a specific target, specific toxicologic effects existed. Diverse diseases along exposure pathways can occur at the same time with a common toxicologic mechanism and cause of HDs, which can be called as HD syndrome. To gain stronger scientific evidence about it, further epidemiological and toxicological studies should be applied ...

Normal right lung. Coloured X-ray showing the branching bronchial tree in a healthy right lung. The tube running from top right to centre is one of two bronchi, one for each lung, which attach to the trachea (windpipe). Inside the lung the bronchus divides into many bronchioles. Each bronchiole becomes smaller, finally ending in alveoli (tiny air sacs, not seen). The lungs are the site of gaseous exchange; oxygen enters the blood and carbon dioxide is removed. - Stock Image P590/0043

Two inserts demonstrate and explain the physiology of inspiration and expiration.
The alveolus is a small, balloon like sac at the end of the small air passages in the lungs (the bronchiole). Oxygen is inhaled and absorbed into the bloodstream through the thin wall of each alveolus, and carbon dioxide is passed the other way (from the blood to the lungs) to be exhaled. There are about 300 million alveoli in each lung.. ...
Bronchiolitis is an acute inflammatory injury of the bronchioles that is usually caused by a viral infection. Although it may occur in persons of any age, severe symptoms are usually only evident in young infants; the larger airways of older children and adults better accommodate mucosal edema.
The season finale of Doctor Who, Hell Bent, concluded the three part story which began with the death of Clara Oswald in Face the Raven. It turned out that the ending of last weeks episode, Heaven Sent, contained some misdirection about where the finale was going. While the Doctor did return to Gallifrey, this was not at all what the episode was really about.. The Doctor returned to Gallifrey as a war hero, and used this return to save Clara. While the leaders on Gallifrey were concerned with the identity of the Hybrid, it turned out that the Doctor did not really know the answer. His priority was in saving Clara.. Face the Raven appeared to end with the Doctor allowing Clara to die as there was way to prevent her death. Now he was willing to break all the rules and risk the fracturing of time to save her. Clara was pulled out of time just before the moment of her death, in between heartbeats and lacking a pulse, not really living. She was informed of her condition by a general on Gallifrey: ...

Air reaches the lungs through a series of ever-smaller tubes. First air passes through the trachea (TRAY-kee-a), which is the large windpipe from the throat down the neck. Then the trachea branches into smaller tubes called the bronchi (BRONG-ky), then into even smaller bronchi called bronchioles (BRONG-kee-olz) that branch still further deep into the lungs. The bronchioles end in tiny air sacs called alveoli. It is in the alveoli that the transfer of oxygen into the bloodstream and of carbon dioxide out of the bloodstream occurs. In emphysema, the bronchi and bronchioles are inflamed and continually swollen and clogged. This causes the alveoli to swell. These fragile air sacs burst and merge together. This damage to the alveoli makes it more difficult for the transfer of oxygen and carbon dioxide to take place. People with emphysema have difficulty breathing. It is usually caused by cigarette smoking, or a severe form of bronchitis called chronic obstructive bronchitis. Very often, a ...
When it comes to diseases of the respiratory system, these occur primarily in the bronchioles and the alveoli unless one takes into account choking and drowning which are basically conditions that affect the larger passageways to the lungs such as the trachea and the bronchi. In the world of today, the diseases that most often affect the bronchioles and alveoli include COPD, emphysema, bronchitis, asthma, allergies, flu, pneumonia, cystic fibrosis, pulmonary fibrosis, and pulmonary embolisms. These are by far the major diseases of the respiratory system killing millions of people all over the world.. COPD COPD or chronic obstructive pulmonary disease is in technical terms a progressive disease. It is most often caused by long-term irritation of the lungs that makes it difficult to breathe. COPD is characterized by airflow limitation that is usually both progressive and associated with an abnormal inflammatory response of the lungs to certain foreign particles and gases. Cigarette smoking is the ...
Fennel seeds are effective in the treatment of cough. These must be taken along with figs for better results.

What is bronchiectasis?. Bronchiectasis is a long term condition affecting the airway tubes (bronchi and bronchioles). The airway tubes become narrower due to inflammation and in certain small areas the breathing tubes develop pockets probably due to both scarring and weakness around the airway. The existence of these pockets in the airways mean that mucus gets trapped. The trapped mucus does not get removed as quickly as usual and this allows bugs that end up in the lung to stay there and cause problems. Once the bugs grow to a certain level a chest infection or flare up occurs. This scarring and inflammation makes sufferers prone to infection. Due to the scarring, bronchiectasis cannot be cured but is treatable.. Symptoms. Symptoms vary between individuals, with some sufferers having only one or two and others all of the symptoms listed below;. ...
These spongy, large, conical, are your lungs. They play a vital role because they are responsible for the supply of oxygen in your body. The oxygen allows the body to burn its fuel, i.e. the nutrients contained in food.. The lungs are divided into two halves, right and left. The right lung has three lobes, while the left has two and has a place for the heart. The lungs of an adult may contain approximately three litres of air. Since the lungs have no muscles themselves, they are the chest muscles that are responsible for the work of breathing. The majority of this work is provided by a thin muscle located at the base of the lungs and called the diaphragm.. Respiration is a phenomenon, this even when you are unconscious. The resting respiratory rate of an average adult is 16 breaths per minute. Air that is inspired by down the trachea to the bronchi that branch into the right or left lung.. The bronchi themselves branch into several bronchioles, which are divided into half a dozen of alveolar ...

The trachea (windpipe) divides into two main bronchi (also mainstem bronchi), the left and the right, at the level of the sternal angle. The right main bronchus is wider, shorter, and more vertical than the left main bronchus. The right main bronchus subdivides into three segmental bronchi while the left main bronchus divides into two. The lobar bronchi divide into tertiary bronchi. Each of the segmental bronchi supplies a bronchopulmonary segment. A bronchopulmonary segment is a division of a lung that is separated from the rest of the lung by a connective tissue septum. This property allows a bronchopulmonary segment to be surgically removed without affecting other segments. There are ten segments per lung, but due to anatomic development, several segmental bronchi in the left lung fuse, giving rise to eight. The segmental bronchi divide into many primary bronchioles which divide into terminal bronchioles, each of which then gives rise to several respiratory bronchioles, which go on to divide ...
Alveoli (site of gas exchange). Upper respiratory tract/conducting zone. The conducting zone begins with the nares (nostrils) of the nose, which open into the nasopharynx (nasal cavity). The primary functions of the nasal passages are to: 1) filter, 2) warm, 3) moisten, and 4) provide resonance in speech. The nasopharynx opens into the oropharynx (behind the oral cavity). The oropharynx leads to the laryngopharynx, and empties into the larynx (voicebox), which contains the vocal cords, passing through the glottis, connecting to the trachea (wind pipe).. Lower respiratory tract/respiratory zone. The trachea leads down to the thoracic cavity (chest) where it divides into the right and left "main stem" bronchi. The subdivision of the bronchus are: primary, secondary, and tertiary divisions (first, second and third levels). In all, they divide 16 more times into even smaller bronchioles.. The bronchioles lead to the respiratory zone of the lungs which consists of respiratory bronchioles, alveolar ...

Professor Sullivan was recently interviewed by the US National Sleep Foundation to share his thoughts on the past, present and future of CPAP. The Foundation has kindly provided permission for Maskmedic to re-publish the interview here.. National Sleep Foundation: What were some of your pivotal moments in the laboratory, and how have these discoveries changed the treatment of sleep apnea?. Colin Sullivan: The pivotal moment was a night in June 1980 when we first tested the idea that positive pressure, applied just through the nasal airway, could stop obstructive apnea.. Although I had the idea several months previously, at that time we saw only very few patients, so we had to wait for an appropriate patient to do the experiments. The patient in whom the first test was done had very severe sleep apnea and had come under my care at the Royal Prince Alfred Hospital where I was a physician in the Respiratory Unit.. He was so severe that I had recommended a tracheotomy as an urgent procedure. ...

Endobronchial and nasal mucosa biopsies were obtained from 5 patients with clinically-stable, diagnosed asthma (ATS criteria). A comparison was made of the presence and distribution of immunocompetent lymphocytes and macrophages within each sample. The distribution of immunocompetent cells within the nasal biopsies of the asthmatic patients reflected a very similar inflammatory infiltrate to that seen in the bronchial biopsies. Significantly raised numbers of T lymphocytes, CD45RO + lymphocytes, RFD1 + macrophage-like cells and RFD7 + macrophages were seen in both the nasal mucosa and the bronchial biopsies. Increases in HLA-DR expression were also seen in the nasal mucosa biopsies from asthmatics although the increases over normal did not reach statistical significance. It is concluded that inflammation present in the nasal mucosa of asymptomatic asthmatics exhibits cellular characteristics also seen in endobronchial biopsies. This observation offers the possibility that mucosal biopsy may be ...
When you inhale, air moves from the nose and mouth, down to the larynx, down through the trachea. It does not reach the lungs until the trachea branches. The branched air passages are called the bronchi. The bronchi carry the air into the lungs. Each bronchus divides 20-30 times, becoming the bronchiole which take the air to the different parts of the lungs. Eventually the air reaches a cluster of "blind sacs" called alveoli, which is where the actual gas exchange occurs. An adult human can have up to 300 million alveoli in his or her lungs ...

The conducting zone is made up nose to bronchioles and its function is to filter, warm, and moisten air and conduct it into the lung. The conducting zone includes the nose, pharynx, larynx, trachea, bronchi and bronchioles. Nares are the opening into the nose and is where nasal cavity is lined with cilia, mucous membrane and consists of blood filled capillaries. The oral cavity id formed by the stomodeum, which is the depression in the embryo located between the brain and the pericardium. This depression is known as the precursor of the mouth and the anterior portion of the pituitary gland. The stomodeum is ectoderm lined depression, separates the primitive pharynx by the buccopharyngeal (oropharyngeal) membrane. The membrane later breaks down and stomodeum opens into the pharynx forms the vestibule of oral cavity. The larynx is developed from endoderm of laryngotracheal tube. The splanchnic mesoderm is important for the development of connective tissue and muscle. The bronchi is formed in week ...
The parenchyma is the functional parts of an organ in the body. This is in contrast to the stroma, which refers to the structural tissue of organs, namely, the connective tissues.. In the brain, the parenchyma refers to the functional tissue in the brain that is made up of the two types of brain cell, neurons and glial cells.[6] Damage or trauma to the brain parenchyma often results in a loss of cognitive ability or even death.. Lung parenchyma is the substance of the lung outside of the circulation system that is involved with gas exchange and includes the alveoli and respiratory bronchioles.[7]. In cancer, the parenchyma refers to "The portion of a tissue that lies outside the circulatory system and is often responsible for carrying out the specialized functions of the tissue".[8]. ...
The main function of the lungs is gas exchange between blood and the air we breathe. The work of the lungs, carbon dioxide is removed from the blood and the inspired oxygen enters the bloodstream. Right lung has three lobes, whereas left lung is divided into two lobes and a smaller structure called the lingula which is equivalent to the middle lobe. Major airways into the lungs are the bronchi, resulting in the trachea. Bronchi branch into progressively smaller airways called bronchiole. They end in small bags known as pulmonary alveoli. The wafers are exchanged gas itself. Lungs and chest wall are covered with a thin layer of tissue called pleura ...

Migration of air from alveolar damage into the mediastinum along the bronchovascular sheath was first demonstrated in 1939 by Macklin. The deep layer of the cervical fascia in the neck encases the trachea and esophagus. This tissue plane extends to the hila of the lungs and connects with the bronchovascular sheath that covers the terminal bronchioles, arteries, and veins. The bronchovascular sheath also interconnects with the pericardium and thus air introduced from alveolar rupture or from the soft tissues of the neck or chest wall can track anywhere along these planes and into the mediastinum.. Tracheal or esophageal mucosal disruption usually occurs from trauma, including procedural manipulation like endoscopy, endotracheal intubation, transesophageal echocardiography, and other manipulations of the tracheobronchial tree or esophagus. Less common causes of mucosal disruption include tumor invasion and emesis (Boerhaaves syndrome).. While alveolar rupture typically results in pneumothorax, ...

Recent in vitro studies indicate that neurons in the pre-Bötzinger (pre-Bot) complex of neonatal rats play an essential role in respiratory rhythm generation. In the adult rat, however, the location and physiology of pre-Bot neurons is less clearly understood. The present study aims to investigate the firing patterns of neurons that are located between Bötzinger and rVRG area, and the precise location of this transition zone in relation to other medullary nuclei. Sprague-Dawley rats (weighted between 400-550 g) were anaesthetised with 72 mg/kg sodium pentobarbitone and 0.4 mg/kg atropine (i.p.), and paralysed with 1 mg/kg pancuronium dibromide (i.v.), followed by additional doses as required. Extracellular recordings were made from 302 respiratory units located between 0 and 1.6 mm caudal to the facial nucleus and ventral to the nucleus ambiguus. As expected, expiratory units were mostly recorded from the rostral medulla (80%, 125/157) and inspiratory units were concentrated in the more caudal ...

Working with coal, whether as a miner or in other ways, results in an accumulation of coal or other dust in macrophages in and around respiratory bronchioles. Mild dilatation of respiratory bronchioles results, probably from atrophy of muscle. The lesion resembles centrilobular emphysema but differs in that the enlarged spaces are smaller and more regular, and inflammation of bronchioles is not apparent. Thus, the lesion is primarily distensive rather than destructive. The anatomic lesion is usually equated with a chest radiograph that shows small nodular densities, although the complete correlation has not been proved. The condition, also referred to as black lung, has been considered to cause severe disability. Contemporary evidence, however, suggests that simple coal pneumoconiosis causes only minor impairment of pulmonary function. When coal miners have severe chronic airflow obstruction, it is usually due to other forms of emphysema, notably tobacco-related centrilobular emphysema. Other ...
Background. Asthma is a chronic airway disease characterized by episodic symptoms that are associated with functional alterations. It is well known that airways inflammation plays a basic role in the pathogenesis of asthma, and many autoptic and bioptic studies have shown that inflammation involves the entire bronchial tree, from proximal to distal airways. Many studies have demonstrated that inflammatory cells, particularly eosinophils, are well represented in both the inner and the outer layer of the small airway walls, sometimes with a higher density in comparison with large airway walls.. Small airways are the most peripheral airways with an internal diameter , 2 mm and in this zone oxygen and carbon dioxide exchanges take place. The contribution of small airways to the development of the clinical features and functional impairment in asthma is incompletely understood, probably due to the unavailability of definite noninvasive techniques for the study of small airways. Pathological changes ...
Groups of 10 male and 10 female B6C3F1 mice were exposed to 0, 10, 25, 75, 150, or 300 ppm (approximately 42, 105, 315, 630, or 1,260 mg/m3) isobutyl nitrite by inhalation for 6 hours per day, 5 days per week for 13 weeks. There were no chemical-related deaths. Final mean body weights and mean body weight gains of 150 and 300 ppm females were significantly less than those of the controls. Final mean body weights and mean body weight gains of exposed groups of males were similar to those of the controls. There were no chemical-related clinical findings. A very mild chemical-related methemoglobinemia occurred in male and female mice in the 150 and 300 ppm groups. A very mild anemia occurred in the 300 ppm groups. In the lung, increased incidences of mild to moderate hyperplasia of the bronchiolar epithelium occurred in males and females exposed to 300 ppm. Minimal hyperplasia occurred in males exposed to 75 ppm or greater and in females exposed to 150 ppm. Minimal epithelial cell hyperplasia of ...
Emphysema is a condition that is typically marked by steady destruction of alveoli, tiny air sacs in the lungs in which ensure inhaled oxygen will be transferred to the system and also carbon dioxide is exhaled out of the body. These air sacs that look like a cluster of grapes are found at the end of the bronchioles (airways). In the initial stages of emphysema, the alveoli appear inflamed, that interferes with the appropriate exchange of oxygen and carbon dioxide. Longterm smoking cigarettes and associated with the are usually said to result in emphysema. Usually, the actual alveoli are usually stretchy but with emphysema their own elasticity is actually impaired. As a result, the particular alveoli tend to be unable residence off carbon dioxide and other harmful particles appropriately from the lungs. This build up of impurities results in excess mucus production in the lungs and it is then followed by shortness of breath and continual coughing ...
