Effect of ETYA and BW 755c on arachidonate-induced contractions in the guinea-pig isolated trachea. 1982

H W Mitchell

1. Arachidonic acid caused larger contractions to indomethacin-tested guinea-pig trachea than in control tracheae. 2. No change in contractions was obtained in tracheae treated with 5,8, 11, 14, eicosatetraynoic acid (ETYA 10 micro M). 3. ETYA (100 micro M) blocked the effect of indomethacin on arachidonic acid-induced responses. Likewise BW 755c (113 micro M) reversed the effect of indomethacin. 4. The results show that arachidonate lipoxygenase products may be responsible for the contractile responses seen in the presence of indomethacin.

UI MeSH Term Description Entries
D007213 Indomethacin A non-steroidal anti-inflammatory agent (NSAID) that inhibits CYCLOOXYGENASE, which is necessary for the formation of PROSTAGLANDINS and other AUTACOIDS. It also inhibits the motility of POLYMORPHONUCLEAR LEUKOCYTES. Amuno,Indocid,Indocin,Indomet 140,Indometacin,Indomethacin Hydrochloride,Metindol,Osmosin
D009119 Muscle Contraction A process leading to shortening and/or development of tension in muscle tissue. Muscle contraction occurs by a sliding filament mechanism whereby actin filaments slide inward among the myosin filaments. Inotropism,Muscular Contraction,Contraction, Muscle,Contraction, Muscular,Contractions, Muscle,Contractions, Muscular,Inotropisms,Muscle Contractions,Muscular Contractions
D009130 Muscle, Smooth Unstriated and unstriped muscle, one of the muscles of the internal organs, blood vessels, hair follicles, etc. Contractile elements are elongated, usually spindle-shaped cells with centrally located nuclei. Smooth muscle fibers are bound together into sheets or bundles by reticular fibers and frequently elastic nets are also abundant.

D000403 Airway Resistance Physiologically, the opposition to flow of air caused by the forces of friction. As a part of pulmonary function testing, it is the ratio of driving pressure to the rate of air flow. Airway Resistances,Resistance, Airway,Resistances, Airway
D000818 Animals Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.
