What's the difference between antagonize and antagonized?

Antagonize


Definition:

  • (v. t.) To contend with; to oppose actively; to counteract.
  • (v. i.) To act in opposition.

Example Sentences:

  • (1) Intrathecal injection of zopiclone potentiated morphine antinociception, while the intracerebroventricular injection of zopiclone failed to enhance morphine antinociception and the intracerebroventricular injection of flumazepil to antagonize the intraperitoneal-zopiclone-induced increase in morphine antinociception.
  • (2) of PLA2 caused marked degranulation of mast cells in the rat mesentery which was facilitated by addition of calcium ion (10 mM) but antagonized by pretreating with three antiinflammatory agents.
  • (3) [Ca2+]i exhibited a sigmoidal dependence on [Na+]o. Mg2+, a competitive inhibitor of Na2+-Ca2+ antiport in these cells, antagonized the increase in [Ca2+]i produced by lowering [Na+]o.
  • (4) Increases in extracellular calcium antagonized the negative inotropic effect.
  • (5) In K+-depolarized basilar arteries, ifenprodil competitively antagonized the response to Ca2+, and this was enhanced by pre-incubation in calcium hopantenate.
  • (6) During the postovulatory phase, endogenous progesterone and the production of metabolites antagonized this effect.
  • (7) An antagonism is unlikely when ciprofloxacin is combined with one of the beta-lactams studied or with tobramycin.
  • (8) Co-application of CGS 9896, a benzodiazepine receptor antagonist, did not antagonize the guanidino compound-induced inhibition of GABA responses.
  • (9) Aortic rings from the rabbit were similarly potently antagonized by the protein kinase C inhibitors, however, K(+)-induced contractions were also equally sensitive to these agents in both rat and rabbit tissues.
  • (10) The biphasic response to (-)-(S)-Bay K 8644 and (+)-(S)-202-791 suggests that the properties of Ca++ channel activation and antagonism may reside within a single 1,4-dihydropyridine molecule.
  • (11) We have investigated the bacterial antagonism exerted in oral secretion by alpha-hemolytic streptococci against S. aureus and S. epidermidis.
  • (12) The marine natural product lophotoxin has produced a non-reversible antagonism of parasympathetic and sympathetic functions that are known to be mediated by C6 sub-type nicotinic receptors.
  • (13) Strains showing occasional antagonism at a particular proportion of concentrations of the test combination, were found to only be indifferent when the mean index of the fractional inhibition concentration of all checkerboard combinations was calculated.
  • (14) The omission of glucose induced a marked increase in the efflux of [3H]GABA, which was antagonized by TTX (1 microM), but not by MK 801 (1 microM) or DNQX (100 microM).
  • (15) The hyperthermia in rabbits caused by the serotonergic stimulants cited above is also antagonized by pretreatment with MS.
  • (16) The neuroleptic agents haloperidol, fluphenazine, domperidone, sulpiride and tiapride also antagonized emesis induced by cisplatin but only a proportion of the animals were completely protected and diazepam and prednisolone only reduced the intensity of the response.
  • (17) These results suggest that formoterol modifies allergen-induced airway responses through functional antagonism rather than the inhibition of inflammatory cell infiltration.
  • (18) Depolarizations induced by acetyl-Arg6-septide, a NK1-receptor selective agonist, were also antagonized by spantide with a pA2 of 6.5.
  • (19) 5-Hydroxytryptamine contracted the musculature from all parts of the respiratory tract-an effect which was specifically antagonized by both methysergide and atropine.4.
  • (20) K showed little activity against LTC4 but could antagonize more selectively H- and ACh-mediated effects.
