Anti-asthmatic agents, also known as anti-asthma drugs, refer to drugs that can aid in airway smooth muscle dilation to allow normal breathing during an asthma attack or reduce inflammation on the airway to decrease airway resistance for asthmatic patients, or both. The goal of asthmatic agents is to reduce asthma exacerbation frequencies and ...
To the average consumer, formaldehyde may be best known as an embalming agent. But this naturally occurring chemical is a major industrial staple, used in many consumer goods, including cleaning ...
In enzymology, a formaldehyde dehydrogenase (EC 1.2.1.46) is an enzyme that catalyzes the chemical reaction formaldehyde + NAD + + H 2 O ⇌ {\displaystyle \rightleftharpoons } formate + NADH + H + The 3 substrates of this enzyme are formaldehyde , NAD + , and H 2 O , whereas its 3 products are formate , NADH , and H + .
Formaldehyde inhaled at this concentration may cause headaches, a burning sensation in the throat, and difficulty breathing, and can trigger or aggravate asthma symptoms. [69] [70] The CDC considers formaldehyde as a systemic poison. Formaldehyde poisoning can cause permanent changes in the nervous system's functions. [71]
Formaldehyde – preservative with multiple uses, e.g., in paper products, paints, medications, household cleaners, cosmetic products, and fabric finishes. Often released into products by the use of formaldehyde releasers such as imidazolidinyl urea, diazolidinyl urea , Quaternium-15 , DMDM Hydantoin, and 2-bromo-2-nitropropane-1,3-diol.
The mechanisms behind allergic asthma—i.e., asthma resulting from an immune response to inhaled allergens—are the best understood of the causal factors. In both people with asthma and people who are free of the disease, inhaled allergens that find their way to the inner airways are ingested by a type of cell known as antigen-presenting ...
An inhaler (puffer, asthma pump or allergy spray) is a medical device used for delivering medicines into the lungs through the work of a person's breathing. This allows medicines to be delivered to and absorbed in the lungs, which provides the ability for targeted medical treatment to this specific region of the body, as well as a reduction in the side effects of oral medications.
They are spiral-shaped mucus plugs from subepithelial mucous gland ducts of bronchi. They may occur in several different lung diseases [1] and may refer to parts of the desquamated epithelium seen in lavages from asthmatic patients. [2] These microscopic casts are named after German physician Heinrich Curschmann (1846-1910).
