Effect of synthetic prostaglandin PGF2 alpha on the volume acidity, and proteolytic activity of the abomasum juice in sheep. Act Physiol. Pol., 1979, 30 (2): 299--304. The investigations were carried out in 3 male sheep on the effect of Estrumate (a synthetic analogue of PGF2 alpha) on the secretion and composition of juice from the "small" abomasum. After intramuscular injection of optimum doses of the preparation (3.0--4.0 micrograms/kg of body weight) it was observed that the volume of the juice, its free HCl content, the total acidity the specific activity (expressed in Anson milliunits/ml) and the total activity (specific activity X volume of juice secreted in a given sample) increased significantly (p less than 0.01). Thus, the synthetic prostaglandin PGF2 alpha stimulates the secretory activity of abomasum glands in sheep.

The investigations were carried out on 7 wethers with cannulated fistulas of the "small" abomasum and rumen. In two series of experiments the optimal dose of one of the tested analogues of PGF 2 alpha (Estrumate 3-4 microgram/kg, Lutalyse 130-170 microgram/kg of body weight) was used. It was found the Estrumate in relation to Lutalyse caused a highly statistical significant rise (P less than 0.01) in the volume of secreted juice, free HCl, and total acidity in the same sheep. The specific activity (Anson mU/ml) increased more after Lutalyse (P less than 0.01) than after Estrumate injection. This analogue also caused significant (P less than 0.02) changes in the total activity (specific activity X juice volume of this sample). The obtained results expressed in per cent indicate that Estrumate exerts a greater effects on the parietal cells in the abomasal mucosa in sheep and Lutalyse stimulates more strongly the chief cells, as reflected in increased proteolytic power of the studied juice.
