  • Effects of cholecystokinin (CCK) on gut motility in the Stomachless fish ballan wrasse (Labrus bergylta)
    2019
    Co-Authors: Le, Hoang Thi My Dung, Lie, Kai Kristoffer, Giroud-argoud Justine, Rønnestad Ivar, Sæle Øystein
    Abstract:

    Cholecystokinin (CCK) is well-known as a key hormone that inhibits Stomach Emptying and stimulates midgut motility in gastric species. However, the function of CCK related to gut motility in agastric fish, especially in fish with a short digestive tract such as ballan wrasse, remains unknown. Here we present a detailed description of the spatio-temporal quantification of intestinal motility activity in vitro comprising the complete intestinal tract in ballan wrasse. We show that CCK modulates intestinal motility, having multiple effects on motility patterns depending on location in the gut and types of contractions. CCK reduced propagating contractions in the foregut, but it increased both non-propagating and propagating contractions in the hindgut. CCK also altered the direction of propagating contractions, as it reduced anterograde ripples and slow propagating contractions. The velocity of propagating contractions was slowed down by CCK. CCK also reduced the amplitude of standing contractions and ripples, but it did not alter the amplitude of slow propagating contractions. The presence of CCKA receptor antagonist modulated the motility responses of ballan wrasse intestines when exposed to CCK. We also showed that CCK reduced the intestinal length and stimulated motility to empty the gallbladder. Based on our findings we hypothesize that CCK, mainly through the CCKA receptor, modulates non-propagating and propagating contractions to optimize digestion and absorption and regulate the intestinal evacuation in ballan wrasse. We also found evidence that the modulation of intestinal motility by CCK is different in agastric fish from that in gastric vertebrates. We suggest that this is an evolutionary adaptation to optimize digestion without a Stomach.publishedVersio

  • differences in in vitro gastric behaviour between homogenized milk and emulsions stabilised by tween 80 whey protein or whey protein and caseinate
    Food Hydrocolloids, 2011
    Co-Authors: George A Van Aken, Esther Bomhof, Franklin D Zoet, Monique Verbeek, Alexander Oosterveld
    Abstract:

    This study focuses on the behaviour of liquid food emulsion systems in the Stomach. Gastric digestion was studied in vitro using a Stomach model consisting of a thermostatted titration vessel to which solutions of HCl, pepsin and a lipase were simultaneously added slowly. Four systems were studied: a whey protein-stabilised emulsion, a whey protein-stabilised emulsion with additional sodium caseinate, a Tween 80 stabilised emulsion, and homogenized full fat milk. It is shown that the in vitro colloidal behaviour of the systems under simulated gastric conditions is influenced significantly by their composition. The Tween 80 stabilised emulsion did not show instabilities, whereas the two protein-stabilised emulsions and full fat milk showed extensive flocculation, which for the protein-stabilized emulsions led to creaming and for full fat milk led to sedimentation. The experimental results also show some coalescence in the Tween 80 and milk systems. The formation of free fatty acids did not vary much between the systems, showing that flocculation and coalescence did not strongly affect lipolysis. The possible physiological relevance of these different behaviours are discussed, suggesting differences in Stomach Emptying rate and feelings of fullness and satiety.
