Example Sentences:

(9) The effects of norepinephrine (NE), histamine (HIST), glutamate, and adenosine, singly and in combinations, on the accumulation of adenosine 3',5'-monophosphate (cyclic AMP) in slices of rabbit cerebral cortex were examined using tissue from animals 4 days before to 38 days after birth.
(10) The present studies were undertaken to obtain histamine (HIST) dose-response curves for tracheal smooth muscle (TSM) from an actively ragweed-sensitized canine model of asthma and to compare these results with 1) HIST dose-response data from littermate control dogs, 2) initially nonsensitized TSM passively sensitized (in vitro) to ragweed and 3) the dose-response curve to an agonist that opens primarily voltage-sensitive calcium channels, i.e., K+.
