RÉSUMÉ
Introduction. L’ulcère gastrique (GU) est l’une des maladies gastriques les plus courantes et le stress oxydatif joue un rôle dans l’installation de l’ulcère gastrique. Objectif de ce travail était d’évaluer l’activité antiulcéreuse de l’extrait décocté de Terminalia superba (EDTS). Méthodes. Pour effectuer ce travail, une étude expérimentale a été menée pendant 8 mois, Après la préparation de l’EDTS, Le potentiel antiulcéreux de l’extrait a été évalué en utilisant un modèle expérimental de rats exposés à une solution HCl/ethanol. Après légère acclimatation (7jours), 25 rats males de souches Wistar d’un poids moyen de 220±6 g ont été utilisés. Les rats ont été répartis en cinq groupes de cinq comme suit : un groupe contrôle négatif (CN) qui recevait uniquement de l’eau distillée, un groupe control positif (CP) qui recevrait une solution HCl/éthanol et de l’eau distillée, un groupe essai 1 qui recevrait une solution HCl/éthanol et 250mg/kg de PC d’EDTS. Un groupe essai 2 qui recevrait une solution HCl/éthanol et 500mg/kg de PC d’EDTS. Un groupe référence qui recevrait une solution HCl/éthanol et 100mg/kg de PC de sucralfate. L’administration de la solution HCl/éthanol a été fait après 48h de jeun et une heure après l’administration de l’extrait/référence. Après 2h, les animaux ont été sacrifiés sous légère anesthésie à l’éther puis le sang collecté dans les tubes secs pour l’obtention du sérum et le contenu l’estomac a été prélève pour la préparation du suc gastrique. Les homogénats d’organes (estomac, foie et reins) ont été préparés. L’estomac a été fixe dans le formol 10% pour la réalisation des coupes histologiques. Résultats. Les résultats obtenus ont montré que l'extrait a enregistré les pourcentages de protection de 70,54%, 72,09% respectivement à la dose 250 et 500mg/kg de PC contre ulcère gastrique induit par HCl/éthanol. L'extrait a augmenté le statut antioxydant et diminué le taux de MDA dans l’estomac. Conclusion. L'étude a révélé que l’EDTS possède un potentiel antiulcéreux. Le mécanisme probable est l’augmentation de statut antioxydant et diminution des marqueurs pro-oxydants dans l’estomac. Les résultats nous ont permis de valider l'utilisation populaire de TS dans le traitement de l’ulcère gastrique,
ABSTRACT
Introduction. Gastric ulcer (GU) is one of the most common gastric diseases and oxidative stress plays a role in the development of gastric ulcer. Objective of this work was to evaluate the antiulcer activity of the decocted extract of Terminalia superba (EDTS). Methods. To carry out this work, an experimental study was carried out for 8 months. After the preparation of the EDTS, the antiulcer potential of the extract was evaluated using an experimental model of rats exposed to an HCl/ethanol solution. After slight acclimatization (7 days), 25 male rats of Wistar strains with an average weight of 220±6 g were used. The rats were divided into five groups of five as follows: a negative control group (NC) which received only distilled water, a positive control group (PC) which would receive an HCl/ethanol solution and distilled water, a trial group 1 which would receive an HCl/ethanol solution and 250 mg/kg of EDTS PC. A trial group 2 which would receive an HCl/ethanol solution and 500mg/kg of EDTS PC. A reference group which would receive an HCl/ethanol solution and 100 mg/kg of sucralfate PC. The administration of the HCl/ethanol solution was done after 48 hours of fasting and one hour after the administration of the extract/reference. After 2 hours, the animals were sacrificed under light ether anesthesia then the blood collected in dry tubes to obtain serum and the stomach contents were collected for the preparation of gastric juice. Organ homogenates (stomach, liver and kidneys) were prepared. The stomach was fixed in 10% formalin for histological sections. Results. The results obtained showed that the extract recorded the protection percentages of 70.54%, 72.09% respectively at the dose 250 and 500mg/kg of PC against gastric ulcer induced by HCl/ethanol. The extract increased the antioxidant status and decreased the level of MDA in the stomach. Conclusion. The study revealed that EDTS has antiulcer potential. The likely mechanism was increased antioxidant status and decreased pro-oxidant markers in the stomach. The results allowed us to validate the popular use of the herbal product in the treatment of gastric ulcer,
