What's the difference between physiological and stimulant?

Physiological


Definition:

  • (17) At physiologic doses (10(-8) M) estradiol inhibits the binding at a significant extent on the soluble receptor, but not on membrane-bound form.
  • (18) With the successful culture of these tissues, their development, biochemistry, and physiology, potentially of great importance in understanding early vertebrate evolution, can be better understood.
  • (19) The binding follows the principle of isotope dilution in the physiologic range of vitamin B12 present in human serum.

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.
  • (2) The optimal size for stimulation was between 5 degrees and 12 degrees (visual angle).
  • (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.

  • (11) Some of those drugs are able to stimulate the macrophages, even in an aspecific way, via the gut associated lymphatic tissue (GALT), that is in connection with the bronchial associated lymphatic tissue (BALT).
