124 results about "Mucous membrane of nose" patented technology

The nasal mucosa lines the nasal cavity. It is part of the respiratory mucosa, the mucous membrane lining the respiratory tract. The nasal mucosa is intimately adherent to the periosteum or perichondrium of the nasal conchae. It is continuous with the skin through the nostrils, and with the mucous membrane of the nasal part of the pharynx through the choanae. From the nasal cavity its continuity with the conjunctiva may be traced, through the nasolacrimal and lacrimal ducts; and with the frontal, ethmoidal, sphenoidal, and maxillary sinuses, through the several openings in the nasal meatuses. The mucous membrane is thickest, and most vascular, over the nasal conchae. It is also thick over the nasal septum where increased numbers of goblet cells produce a greater amount of nasal mucus. It is very thin in the meatuses on the floor of the nasal cavities, and in the various sinuses. It is one of the most commonly infected tissues in adults and children. Inflammation of this tissue may cause significant impairment of daily activities, with symptoms such as stuffy nose, headache, mouth breathing, etc.

Oxymetazoline hydrochloride nasal spray and preparation method thereof

The invention belongs to the technical field of medicines, and provides an oxymetazoline hydrochloride nasal spray and a preparation method thereof.

Thermosensitive gel and preparation method thereof

The invention discloses thermosensitive gel and a preparation method thereof. Albiflorin with antidepressant activity is carried into nanogel particles to serve as drug-release reservoirs, and throughthe interaction between alginic acid and poloxamer molecular chain segments, the albiflorin-zinc alginate thermosensitive self-assembled gel is constructed. According to the albiflorin controlled-release antidepressant thermosensitive gel prepared through the method, the mode of drug administration through the nose is adopted, and thus the gel can adhere to the surface of the nasal mucosa at thebody temperature to continuously release a drug; the albiflorin directly enters the brain through an olfactory region, is not limited by blood-brain barriers, and can quickly take effect to treat depression; pharmacodynamic experiments prove that an albiflorin thermosensitive self-assembled gel preparation is superior to other drugs or preparation formulations in the aspect of quickly taking effect to resist depression; and the drug delivery and absorption efficiency is improved, the onset time is shortened, a more suitable and more effective novel preparation formulation is provided for treating depression through the albiflorin, and the application range of the thermosensitive gel is enlarged.
