Both prostaglandin E1 (PGE1) and prostaglandin F2α (PGF2α) stimulate the glycogen phosphorylase (EC 2.4.1.1.) activity of Fasciola hepatica. Whole or sliced parasites were incubated with PGE1 (2.8 × 10-7 and 2.8 × 10-5M) and PGF2α(2.1 × 10-7 and 2.1 × 10-5 M) and enzyme activity was measured in homogenates prepared immediately following the incubation. No substantially different effect was noted between the two assayed doses of prostaglandins. Prostaglandins appeared to be less effective in sliced parasites.

Abstract
Both prostaglandin E1 (PGE1) and prostaglandin F2α (PGF2α) stimulate the glycogen phosphorylase (EC 2.4.1.1.) activity of Fasciola hepatica. Whole or sliced parasites were incubated with PGE1 (2.8 × 10-7 and 2.8 × 10-5M) and PGF2α(2.1 × 10-7 and 2.1 × 10-5 M) and enzyme activity was measured in homogenates prepared immediately following the incubation. No substantially different effect was noted between the two assayed doses of prostaglandins. Prostaglandins appeared to be less effective in sliced parasites.
