  • Title: Effect of proximal selective vagotomy on gastric prostaglandin content in the Shay-rat ulcer model.
    Author: Dubecz S, Szombath D, Rózsa I, Lippert H, Gáti T, Ihász M.
    Journal: Acta Physiol Hung; 1989; 74(1):3-8. PubMed ID: 2618739.
    Abstract:
    During Shay-ulcer formation damages to the barrier of the gastric mucosa develop even before the appearance of macroscopic ulceration. Proximal selective vagotomy prevents these damages. Following pyloric ligation the prostaglandin content of the mucosa changes in parallel with the injuries of the mucosal barrier: TXB2 content of the forestomach increases, while PGF2 alpha content of both the forestomach and the antrum decreases. Following PSV operation the 6-keto-PGF1 alpha content of the mucosa decreases, whereas PGF2 alpha and TXB2 contents exhibit no alteration. As a combined effect of proximal selective vagotomy pretreatment and pyloric ligation the 6-keto-PGF1 alpha and PGF2 alpha contents of the mucosa remain low and the TXB2 increase, otherwise detectable after pyloric ligation, does not take place.
