  • (18) It is concluded that from the clinical stand point, neither amyl nitrite administration nor standing up can be used as a test to assess acurately the degree of beta blockade, because both procedures activate vagal withdrawal which increases heart rate regardless of the degree of beta blockade.
  • (19) In this study ethanol and certain other short-chain aryl (benzyl and phenethyl) and aliphatic (methyl, propyl, butyl, and amyl) alcohols produced up to 10-fold increases in cyclic AMP (cAMP) concentrations in purified human peripheral blood lymphocytes.

Amyloid


Definition:

  • (a.) Alt. of Amyloidal
  • (n.) A non-nitrogenous starchy food; a starchlike substance.
  • (n.) The substance deposited in the organs in amyloid degeneration.

Example Sentences:
