Effect of the GABAB agonist baclofen on dipyrone-induced delayed gastric emptying in rats. E.F. Collares and A.M. Vinagre. Brazilian Journal of Medical and Biological Research, 38 (1): 99, 2005.

Figure 2. Gastric retention of a saline test meal 10 min after orogastric administration to rats. Eight days before the experiment, all animals were implanted with a stainless steel cannula into the right lateral ventricle. The animals were injected icv through an internal cannula with 5 µl vehicle (C) or an equal volume of solution containing 4 µmol (1333.2 µg) dipyrone (Dp), followed by injection of 5 µl vehicle (bac0) or an equal volume of solution containing 1 µg baclofen (bac1). Gastric retention, reported as mean ± SEM in % for N = 8 animals, was determined 10 min after removal of the internal cannula. *P < 0.01 (Tukey test).
