Cerumenolytic
A cerumenolytic is an ear wax (cerumen) softening agent. Common cerumenolytics such as hydrogen peroxide and hydrogen peroxide - urea are topical preparations used to facilitate the removal of ear wax. Their side effects tend to be mild, including ear discomfort, transient loss of hearing, dizziness, and local irritation. Medical uses Cerumenolytics are used to soften and break up ear wax. Using a cerumenolytic can reduce the need for flushing the ear with irrigants for wax removal. Additionally, cerumenolytics can also facilitate the manual removal of ear wax. Overall, all cerumenolytics are considered to be equivalent in efficacy. Cerumenolytics are administered directly into the ear, which is a form of topical administration that can be specified as "ototopical." Generally, the use of a cerumenolytic involves instilling several drops of the product into the affected ear once or twice daily for a treatment duration of 3 to 5 days. Each instillation is relatively quick (less than ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cerumen
Earwax, also known by the medical term cerumen, is a brown, orange, red, yellowish or gray waxy substance secreted in the ear canal of humans and other mammals. It protects the skin of the human ear canal, assists in cleaning and lubrication, and provides protection against bacteria, fungi, and water. Earwax consists of dead skin cells, hair, and the secretions of cerumen by the ceruminous and sebaceous glands of the outer ear canal. Major components of earwax are long chain fatty acids, both saturated and unsaturated, alcohols, squalene, and cholesterol. Excess or compacted cerumen is the buildup of ear wax causing a blockage in the ear canal and it can press against the eardrum or block the outside ear canal or hearing aids, potentially causing hearing loss. Physiology Cerumen is produced in the cartilaginous portion which is the outer third portion of the ear canal. It is a mixture of viscous secretions from sebaceous glands and less-viscous ones from modified apocri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dioctyl Calcium Sulfosuccinate
Docusate is the common chemical and pharmaceutical name of the anion bis(2-ethylhexyl) sulfosuccinate, also commonly called dioctyl sulfosuccinate (DOSS). It is on the World Health Organization's List of Essential Medicines. Salts of this anion, especially docusate sodium, are widely used in medicine as laxatives and as stool softeners, by mouth or rectally. In 2020, it was the 163rd most commonly prescribed medication in the United States, with more than 3million prescriptions. Some studies claim that docusate is not more effective than a placebo for improving constipation. Other docusate salts with medical use include those of calcium and potassium. Docusate salts are also used as food additives, emulsifiers, dispersants, and wetting agents, among other uses. History Sodium docusate was patented in 1937 by Coleman R. Caryl and Alphons O. Jaeger for American Cyanamid, which commercialized it for many years as a detergent under the brand name Aerosol OT. Its use for the tre ...

Otitis
Otitis is a general term for inflammation or infection, inner ear infection, middle ear infection of the ear, in both humans and other animals. When infection is present, it may be viral or bacterial. When inflammation is present due to fluid build up in the middle ear and infection is not present it is considereOtitis media with effusion It is subdivided into the following: * ''Otitis externa'', external otitis, or "swimmer's ear", involves the outer ear and ear canal. In external otitis, we see tenderness in the pinna—i.e., the outer ear hurts when touched or pulled. * ''Otitis media'', or middle ear infection, involves the middle ear. In otitis media, the ear is infected or clogged with fluid behind the ear drum, in the normally air-filled middle-ear space. This is the most common infection and very common in babies below 6 months. This condition sometimes requires a surgical procedure called ''myringotomy'' and tube insertion. * ''Otitis interna'', or labyrinthitis, involve ...

Effervescence
Effervescence is the escape of gas from an aqueous solution and the foaming or fizzing that results from that release. The word effervescence is derived from the Latin verb ''fervere'' (to boil), preceded by the adverb ''ex''. It has the same linguistic root as the word fermentation. Effervescence can also be observed when opening a bottle of champagne, beer or carbonated beverages such as some carbonated soft drinks. The visible bubbles are produced by the escape from solution of the dissolved gas (which itself is not visible while dissolved in the liquid). Although CO2 is most common for beverages, nitrogen gas is sometimes deliberately added to certain beers. The smaller bubble size creates a smoother beer head. Due to the poor solubility of nitrogen in beer, kegs or widgets are used for this. In the laboratory, a common example of effervescence is seen if hydrochloric acid is added to a block of limestone. If a few pieces of marble or an antacid tablet are put in hydrochlor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Corneocytes
Corneocytes are terminally differentiated keratinocytes and compose most of the stratum corneum, the outermost layer of the epidermis. They are regularly replaced through desquamation and renewal from lower epidermal layers and are essential for its function as a skin barrier. Structure Corneocytes are keratinocytes without nuclei and cytoplasmic organelles. They contain a highly insoluble cornified envelope within the plasma membrane, and lipids (fatty acids, sterols and ceramides) released from lamellar bodies within the epidermis. The corneocytes are interlocked with each other and organized as vertical columns of 10–30 cells to form the stratum corneum. Corneocytes in the lower part of the stratum corneum are bridged together through specialized junctions ( corneodesmosomes). Those junctions disintegrate as corneocytes migrate toward the surface of the skin and result in desquamation. At the same time, as those loosened junctions encounter more hydration, they will expan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Organic Chemicals
In chemistry, organic compounds are generally any chemical compounds that contain carbon-hydrogen or carbon-carbon bonds. Due to carbon's ability to catenate (form chains with other carbon atoms), millions of organic compounds are known. The study of the properties, reactions, and syntheses of organic compounds comprise the discipline known as organic chemistry. For historical reasons, a few classes of carbon-containing compounds (e.g., carbonate salts and cyanide salts), along with a few other exceptions (e.g., carbon dioxide, hydrogen cyanide), are not classified as organic compounds and are considered inorganic. Other than those just named, little consensus exists among chemists on precisely which carbon-containing compounds are excluded, making any rigorous definition of an organic compound elusive. Although organic compounds make up only a small percentage of Earth's crust, they are of central importance because all known life is based on organic compounds. Living thin ...

Otitis Externa
Otitis externa, also called swimmer's ear, is inflammation of the ear canal. It often presents with ear pain, swelling of the ear canal, and occasionally decreased hearing. Typically there is pain with movement of the outer ear. A high fever is typically not present except in severe cases. Otitis externa may be acute (lasting less than six weeks) or chronic (lasting more than three months). Acute cases are typically due to bacterial infection, and chronic cases are often due to allergies and autoimmune disorders. the most common cause of Otitis externa is bacterial. Risk factors for acute cases include swimming, minor trauma from cleaning, using hearing aids and ear plugs, and other skin problems, such as psoriasis and dermatitis. People with diabetes are at risk of a severe form of ''malignant otitis externa''. Diagnosis is based on the signs and symptoms. Culturing the ear canal may be useful in chronic or severe cases. Acetic acid ear drops may be used as a preventive measur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tympanic Membrane
In the anatomy of humans and various other tetrapods, the eardrum, also called the tympanic membrane or myringa, is a thin, cone-shaped membrane that separates the external ear from the middle ear. Its function is to transmit sound from the air to the ossicles inside the middle ear, and then to the oval window in the fluid-filled cochlea. Hence, it ultimately converts and amplifies vibration in the air to vibration in cochlear fluid. The malleus bone bridges the gap between the eardrum and the other ossicles. Rupture or perforation of the eardrum can lead to conductive hearing loss. Collapse or retraction of the eardrum can cause conductive hearing loss or cholesteatoma. Structure Orientation and relations The tympanic membrane is oriented obliquely in the anteroposterior, mediolateral, and superoinferior planes. Consequently, its superoposterior end lies lateral to its anteroinferior end. Anatomically, it relates superiorly to the middle cranial fossa, posteriorly to the o ...

An army (from Old French ''armee'', itself derived from the Latin verb ''armāre'', meaning "to arm", and related to the Latin noun ''arma'', meaning "arms" or "weapons"), ground force or land force is a fighting force that fights primarily on land. In the broadest sense, it is the land-based military branch, service branch or armed service of a nation or country. It may also include aviation assets by possessing an army aviation component. Within a national military force, the word army may also mean a field army. In some countries, such as France and China, the term "army", especially in its plural form "armies", has the broader meaning of armed forces as a whole, while retaining the colloquial sense of land forces. To differentiate the colloquial army from the formal concept of military force, the term is qualified, for example in France the land force is called ''Armée de terre'', meaning Land Army, and the air and space force is called ''Armée de l'Air et de l’Espace' ...

Carbamide Peroxide
Hydrogen peroxide - urea (also called Hyperol, artizone, urea hydrogen peroxide, and UHP) is a solid composed of equal amounts of hydrogen peroxide and urea. This compound is a white crystalline solid which dissolves in water to give free hydrogen peroxide. Hydrogen peroxide - urea contains solid and water-free hydrogen peroxide, which offers a higher stability and better controllability than liquid hydrogen peroxide when used as an oxidizing agent. Often called carbamide peroxide in the dental office, it is used as a source of hydrogen peroxide for bleaching, disinfection, and oxidation. Production For the preparation of the complex, urea is dissolved in 30% hydrogen peroxide (molar ratio 2:3) at temperatures below 60 °C. upon cooling this solution, hydrogen peroxide - urea precipitates in the form of small platelets. Determination of the hydrogen peroxide content by titration with potassium permanganate solution gives a value of 35.4% which corresponds to 97.8% of the th ...
