MeSH

A milky, product excreted from the latex canals of a variety of plant species that contain cauotchouc. Latex is composed of 25-35% caoutchouc, 60-75% water, 2% protein, 2% resin, 1.5% sugar and 1% ash. RUBBER is made by the removal of water from latex.(From Concise Encyclopedia Biochemistry and Molecular Biology, 3rd ed). Hevein proteins are responsible for LATEX HYPERSENSITIVITY. Latexes are used as inert vehicles to carry antibodies or antigens in LATEX FIXATION TESTS.

Year introduced: 1981(1963-1967)

Allergic reaction to products containing processed natural rubber latex such as rubber gloves, condoms, catheters, dental dams, balloons, and sporting equipment. Both T-cell mediated (HYPERSENSITIVITY, DELAYED) and IgE antibody-mediated (HYPERSENSITIVITY, IMMEDIATE) allergic responses are possible. Delayed hypersensitivity results from exposure to antioxidants present in the rubber; immediate hypersensitivity results from exposure to a latex protein.

Year introduced: 2002

Passive agglutination tests in which antigen is adsorbed onto latex particles which then clump in the presence of antibody specific for the adsorbed antigen. (From Stedman, 26th ed)

Year introduced: 1965(1964)

Small uniformly-sized spherical particles, of micrometer dimensions, frequently labeled with radioisotopes or various reagents acting as tags or markers.

Year introduced: 1974(1972)

A high-molecular-weight polymeric elastomer derived from the milk juice (LATEX) of HEVEA brasiliensis and other trees and plants. It is a substance that can be stretched at room temperature to at least twice its original length and after releasing the stress, retract rapidly, and recover its original dimensions fully.

Date introduced: June 28, 2015

A plant genus of the family SAPOTACEAE. Latex from bark incisions is processed into GUTTA-PERCHA.

Year introduced: 2003

A plant genus of the family SAPOTACEAE. Members contain triterpenoid saponins. Latex from bark incisions is processed into gutta balata.

Year introduced: 2003

A plant genus of the family EUPHORBIACEAE. The trees contain hippomanin A and the latex is a skin irritant.

Year introduced: 2003

A plant family of the order Eucommiales, subclass Hamamelidae, class Magnoliopsida (some botanists have classified this in the order Hamamelidales or Urticales). Eucomia is an elmlike tree of central and eastern China. Leaves are alternate; deciduous flowers are solitary and unisexual and lack petals and sepals. The male flowers have 6 to 10 stamens and female flowers have one ovary of two carpels, one of which aborts during development so the fruit (a dry, winged structure) contains only one seed. The latex is a source of RUBBER. Tochu tea is an aqueous extract of Eucommia ulmoides leaves and a popular beverage in Japan. (Mutat Res 1997 Jan 15;388(1):7-20).

Year introduced: 2003

A plant genus of the family MORACEAE. It is the source of the familiar fig fruit and the latex from this tree contains FICAIN.

Year introduced: 2002

A plant family of the order Ebenales, subclass Dilleniidae, class Magnoliopsida that are tropical trees which have elongate latex cells. Several members bear sweet edible fruits and produce triterpenoid saponins.

Year introduced: 2002

The mulberry plant family of the order Urticales, subclass Hamamelidae, class Magnoliopsida. They have milky latex and small, petalless male or female flowers.

Year introduced: 2002

A contact dermatitis due to allergic sensitization to various substances. These substances subsequently produce inflammatory reactions in the skin of those who have acquired hypersensitivity to them as a result of prior exposure.

Year introduced: 1993

Sheets of latex rubber punched and placed over the teeth during dental procedures to isolate the field of operation from the rest of the oral cavity (Jablonski; Illustrated Dictionary of Dentistry, 1982). Rubber dams are useful in preventing the swallowing of instruments or restorations during dental work.
