Sedative


Definition:

  • (a.) Tending to calm, moderate, or tranquilize
  • (a.) allaying irritability and irritation; assuaging pain.
  • (n.) A remedy which allays irritability and irritation, and irritative activity or pain.

  • (19) Both drugs were relatively well tolerated, but trimipramine had a sedative effect which proved troublesome in some patients.
  • (20) None of the patients required anaesthesia, analgesics or sedatives.

Stimulant


Definition:

  • (a.) Serving to stimulate.
  • (a.) Produced increased vital action in the organism, or in any of its parts.
  • (n.) That which stimulates, provokes, or excites.
  • (n.) An agent which produces a temporary increase of vital activity in the organism, or in any of its parts; -- sometimes used without qualification to signify an alcoholic beverage used as a stimulant.

Example Sentences:

  • (1) Stimulation of human leukocytes with various chemical mediators such as TPA, f-Met-Leu-Phe, LTB4, etc.

  • (3) After stimulation with lipopolysaccharide and calcium ionophore A23187, culture supernatants of clones c18A and c29A showed cytotoxic activity against human melanoma A375 Met-Mix and other cell lines which were resistant to the tumor necrosis factor, lymphotoxin and interleukin 1.
  • (4) Apparently, the irradiation with visible light of a low intensity creates an additional proton gradient and thus stimulates a new replication and division cycle in the population of cells whose membranes do not have delta pH necessary for the initiation of these processes.
  • (5) In conclusion, in S-rats a glucose-stimulated insulin release is accompanied by an increase in IBF, but this is not observed in P-rats.
  • (6) Stimulation is also observed with mixtures of APC expressing DPw3 and APC expressing A1, and likewise, DPw3+ APC become stimulatory when preincubated with supernatants from A1-positive cells.
  • (7) We have previously shown that serotonin is present in secretory granules of frog adrenochromaffin cells; concurrently, we have demonstrated that serotonin is a potent stimulator of corticosterone and aldosterone secretion by adrenocortical cells.
  • (8) Cyclic AMP stimulated phosphorylation by [gamma-32P]ATP of two proteins of apparent Mr = 20,000 and 7,000 that were concentrated in sarcoplasmic reticulum, but the stimulation was markedly dependent on the presence of added soluble cyclic AMP-dependent protein kinase.
  • (9) We have investigated a physiological role of endogenous insulin on exocrine pancreatic secretion stimulated by a liquid meal as well as exogenous secretin and cholecystokinin octapeptide (CCK-8) in conscious rats.
