Porsolt has long-standing extensive expertise in gastrointestinal efficacy pharmacology and safety. We provide models that focus on different gastrointestinal indications and on different parts of the gastrointestinal system. Porsolt also continues to develop and validate new and relevant models.
Colonic motility is defined by the movements of the digestive system, and the transit of its contents.
|Anti-diarrhea (castor oil)||Mouse - Rat|
|Colonic transit (bead model)||Mouse - Rat|
|Fecal consistency||Mouse - Rat|
Emesis is the act or process of vomiting caused by certain certain stimuli or agents.
|Early and delayed emesis (telemetry)||Ferret|
|Early anti-emetic activity (morphine, cisplatin, emetine,…)||Ferret|
Food allergy is an abnormal immune response to food with varying symptoms ranging from mild to severe.
Gastric emptying measures the time it takes for food to empty from the stomach to the small intestine.
|Gastric emptying (measurement of plasma acetaminophen levels)||Rat|
|Gastric emptying (phenol red test)||Mouse - Rat|
Transit measures the time it takes for food to travel through the digestive tract.
|Charcoal meal test||Mouse - Rat|
|Distribution pattern of phenol red||Mouse|
Gastroparesis is a disease in which the stomach cannot empty itself of food in a usual fashion.
|Clonidine-induced delayed gastric emptying (liquid meal)||Rat|
|Clonidine-induced delayed gastricemptying (solid meal)||Rat|
|Post operative ileus||Mouse|
Intestinal mucositis is damage that occurs to the mucosal membrane of the gastro-intestinal tract.
|Chemotherapy-induced intestinal mucositis||Mouse - Rat|
Ulcerogenic activity occurs as a result of different insults to the gastro-intestinal tract.
