“…For example, gastric emptying was strongly affected [109] as total vagal deafferentation results in a severe retention of gastric contents. It was established that retention results from the loss of all afferences, while the concomitant reduced volume of efferences is of little importance.…”

-The contribution of the research group set up by Rérat in the early 1960s in Jouy-en-Josas, and then expanded to Rennes, is summarised. As digestive processes are a major key to the nutritional status of monogastric animals, original methodologies based on advanced experimental surgery were developed in the pig to quantify the digestion and absorption yield, to know their factors of variation, and to understand their physiological and nutritional consequences. The group also extended its expertise to the control of food intake, the role of the nervous system and regulatory peptides, and several biomedical gut-related topics. pig / digestion / absorption / neurohumoral regulation / adaptationRésumé -Réalisations et succès de la recherche française : quarante ans de physiologie digestive chez le porc. Dès le début des années 60, un groupe de recherches a été constitué à l'initiative de A. Rérat à Jouy-en-Josas pour étudier divers aspects de la physiologie digestive chez le porc. Leur exploration a fourni des clés essentielles pour la maîtrise du statut nutritionnel chez cette espèce monogastrique, et un instrument d'amélioration de la production porcine. Ce groupe s'est élargi au fil des années et a même essaimé dans les années 80, notamment à Rennes. Il a apporté une contribution essentielle par le développement de méthodologies nouvelles généralement basées sur une chirurgie expérimentale très élaborée. Ces approches ont fourni de nombreux travaux originaux qui ont permis de décrire les processus de digestion (motricité, transit, sécrétions, hydrolyses enzymatiques

The pig, as an omnivorous animal, seems to be especially valuable species in "gastrointestinal" experiments. The importance of the pylorus in the proper functioning of the digestive tract is widely accepted. Although it is commonly known that sensory innervation plays an important role in the regulation of gastric activity and gastrointestinal tissue resistance, there is complete lack of data on the extrinsic afferents projecting to the swine pylorus. The present experiment has been designed to discover the precise localization and neurochemical properties of the primary sensory neurons projecting to the porcine pylorus. Combined retrograde tracing technique and double immunocytochemistry were applied in five piglets. An additional RT-PCR reaction was used to confirm the presence of all investigated neurotransmitters in the studied ganglia. Traced neurons were localized within the bilateral nodose ganglia of the vagus and bilateral dorsal root ganglia spreading from Th4 to L1. Fast Blue-positive afferents expressed immunoreactivity to substance P, calcitonin gene-related peptide, neuronal isoform of nitric oxide synthase, and galanin. In the vagal and spinal ganglia, the percentages of traced neurons immunoreactive to these substances were 54.8, 10.7, 49.6, 7.4 % and 22.2, 75.5, 95.2 %, respectively, and the solitary perikarya were Gal immunoreactive. The presence of all substances studied in the ganglion tissue was confirmed by RT-PCR technique.
