The nutritional quality of the three infant flours we developed indicates 11.07% - 12.47% protein content, 9.92% - 14.87% fat content, 58.85% - 68.06% carbohydrate content, 1.50% - 2.18% ash and an energy intake varying between 399.84 and 439.37 Kcal. Functionally, our prepared flours have a water absorption capacity between 219.05 and 317.86 mL/g, an oil absorption capacity of 0.19 mL/g, a water solubility index varying from 29.66 - 41.03 and a swelling capacity of 250% - 320%.展开更多

However, Terminalia mantaly H. Perrier could present potential health effects on patients. In order to determine the possible cardiotoxic effects of the hydro-alcoholic extract of the bark of Terminalia mantaly H. Perrier, (HAEBTM) forty (40) rats distributed randomly into 4 groups, including 10 animals per group (5 males and 5 females) were used. Animals in group 1 received distilled water and were used as a control group. On the other hand, groups 2, 3, 4 received oral administration a volume of the hydroalcoholic extract of Terminalia mantaly H. Perrier corresponding to 1 mL/100g of body weight at 150 mg/kg, 300 mg/kg, 600 mg/kg, respectively. The extract was administered daily at the same time for 28 days and serum was collected once a week to evaluate cardiac biochemical markers using spectrophotometric methods using a Cobas C311 HITACHI biochemistry system. After one month of study, all rats were euthanized by overdose of ether, and the hearts of the rats were removed for gross morphological and histopathological analysis. Results were analysed using variance analysis (ANOVA) to compare outcomes as a function of doses administered and treatment times. The biochemical parameters ALT, LDH, CPK, CPKMB showed no significant change (p Terminalia mantaly showed no lesions, edema and necrosis. These results suggest that the hydroalcoholic extract of Terminalia mantaly did not interfere with the functioning or alter the integrity of the heart.展开更多

The cost of its treatment, particularly for populations in developing countries like Senegal, requires an alternative which consists of developing research into new therapeutic approaches with the use of plants from traditional pharmacopoeia. The objective of this study was to determine whether the hydroalcoholic extract of Terminalia avicennioides leaves has a preventive effect on the constriction of tracheal smooth muscle induced by Acetylcholine in Wistar strain rats. Methods: The species used in our experiments were male Wistar rats aged between 12 and 14 weeks. Rings of rat trachea were suspended in isolated organ chambers connected to tension sensors. Two pharmacological agents were used: acetylcholine, for its constrictor effect and adrenaline, for its dilating effect on the pulmonary trachea. Our plant material consisted of a hydroalcoholic extract of Terminalia avicennioides leaves. The experimental protocol was that of the preventive model which consisted of impregnating these rings with the extract at a defined concentration then testing its contractility in the presence of Acetylcholine which was the contractile agonist used in this study. The preventive effect of the extract was studied with an Acetylcholine contraction range on rings pre-incubated with Terminalia avicennioides extract. Results: The results showed that Acetylcholine contracts the trachea and the increase in its contractility was dependent on the dose of Ach added cumulatively (10<sup>−5</sup> to 4 × 10<sup>−5</sup> mol/l). The administration of the hydroalcoholic extract of Terminalia avicennioides leaves led to a modification of the contractile response to Acetylcholine. Indeed, this extract induced a significant attenuation of the contractile responses of the treated tracheal rings compared to those untreated. Conclusion: Terminalia avicennioides had a relaxing effect on tracheal smooth muscle and this effect could play an important role in the prevention of bronchial hyperreactivity in certain respiratory diseases, particularly asthmatic disease.展开更多
