Adherent gum

Xylitol is used as a sweetener in many foods, including low-calorie candies, gums, and breath mints. It prevents bacteria from adhering to cells in the mouth and gums. It also binds to calcium and aids in remineralizing tooth enamel and bones. 

An alternative to the oral route is the buccal mucoadhesive system. The Striant buccal system adheres to the inside of the mouth and the testosterone is absorbed through the oral mucosa and delivered to the systemic circulation. There is no first-pass effect, as the liver is bypassed by this route of administration. Patients apply a 30-mg tablet to the upper gum twice daily. The cost is similar to that of the patch or gel. Side effects unique to this dosage form include oral irritation, bitter taste, and gum edema. 

Extracellular material of a slimy or gelatinous nature is formed by many bacteria, especially those producing mucoid growths. This material may remain firmly adherent as a discrete covering layer on each cell, or it may part freely from the cells. In the former case it is known as a capsule in the latter, as free slime or gum. 

The term bioadhesion ean be defined as the ability of a material (synthetic or natural) to stick (adhere) to a biological tissue for extended periods of time [27]. The phenomenon of bioadhesion can be visualized as a two-step process. The first step involves the initial contaet between polymer and the biological tissue. The second step is the formation of seeondary bonds due to noncovalent interactions. The strength of bioadhesion (expressed as the foree of detachment) for a novel oligosaccharide gum Hakea Gibbosa) contained in a buccal tablet developed by Alur et al. [28,29]... 

Charcoal is used as a fuel and burning rate stabiliser while dextrin (starch gum) forms a viscous dispersion in water such that it can be added to the pyrotechnic ingredients to form a slurry that will adhere to the wires when dipped. It is normally necessary to dip the wires several times in order to build up a satisfactory coating before drying in a current of warm air. 

Existing deposits Gums and adherent deposits can be removed from fuel storage and distribution system components... 

Fuel olefins have been implicated as the primary cause of deposits in gasoline fuel injectors and carburetors. High-boiling-point, high-molecular-weight aromatic components have also been shown to contribute to intake system deposit and gum formation. Once formed, other compounds in the fuel can adhere to these deposits to form an amorphous-type deposit. 

Gum Lac or Shellac. It is obtd from a resin secreted by the insect Laccifer lacca and deposited on the twigs of various species of trees in India, Siam and Indo-China. The collected material is dried, ground and washed to remove the adherent red dye. 

The porosity of the biscuit causes the burnt pipes to absorb water with avidity, and to adhere in a very unpleasant manner to the lips. The ends of the sterna are therefore either rubbed with a mixture composed of gum, soap, and wax, or coated with resin or shellac. Sometimes they are glazed by dipping into a very fusible lead glazo the covered ends boing afterwards exposed ta the flame of the furnace for about ton minutes. 

Guar gum can cause occupational rhinitis (5) and asthma (6). Of 162 employees at a carpet-manufacturing plant where guar gum was used to adhere dye to the fiber, 37 (23%) had a history suggestive of occupational asthma and 59 (36%) occupational rhinitis (7). Eight (5%) had immediate skin reactivity to guar gum and 11 (8.3%) had serum IgE antibodies to guar gum. 

One interesting application of RIM-technology is the production of gum-coated parts. Liquid polymerizing mixtures flow easily around inserts and can adhere strongly to metal surfaces. Inserts can be made of practically any material, except those which interact with components of the RIM-mixture. There are few other technological processes that can produce gummed parts of any size and shape by a one-shot procedure. 

Buccastem tablets are a form of prochlorperazine for buccal administration, containing 3 mg of prochlorperazine in a polysaccharide base. When placed in position the tablet softens over a period of a few minutes to form a gel which adheres to the gum and gradually releases the dmg. 

Many substances, such as gums, have a variable viscosity, and most of them are less resistant to flow at higher flow (more correctly, shear) rates. In such cases, select a given set of conditions for measurement, and consider the measurement obtained to be an apparent viscosity. Since a change in the conditions of measurement would yield a different value for the apparent viscosity of such substances, the operator must closely adhere to the instrument dimensions and conditions for measurement.
