title: The effect of PGF2 alpha-estrumate on the secretion and composition of abomasal juice in sheep during H2-histaminic receptor blockade with cimetidine.
abstract: The effect of PGF2 alpha was investigated on the secretion of abomasal juice in sheep after blockade of the H2-histaminic receptor with intravenous cimetidine (150-200 mg). Cimetidine inhibited abomasal juice secretion diminishing juice volume and the content of acid and pepsin in it. During this inhibition intramuscular injection of PGF2 alpha 2.0-4.0 micrograms/kg of body weight caused an increase of these parameters. In control experiments histamine administered (23-28 micrograms/kg) after cimetidine failed to increase the secretion of abomasal juice confirming thus complete blockade of the H2-histaminic receptor. The obtained results demonstrated that the stimulating effect of PGF2 alpha on abomasal juice secretion was not mediated by the H2-histaminic receptor.
