L'activité des associations peut être déterminée par les méthodes couramment employées par l'homme de l'art dans le domaine du diabète. Parmi ces méthodes on peut en particulier utiliser les méthodes suivantes :The activity of the associations can be determined by the methods commonly used by those skilled in the art in the field of diabetes. Among these methods, the following methods can in particular be used:
A - activité en dose unique, chez le rat traité à la streptozotocineA - single dose activity in rats treated with streptozotocin
Des rats Wistar mâles pesant 180 à 200 g sont rendus diabétiques par injection intraveineuse de 60 mg/kg de streptozotocine. Au bout de 72 heures, la glycémie des animaux est mesurée au glucomètre. Les animaux dont la glycémie est inférieure à 2 g/1 ne sont pas retenus pour l'étude et ceux présentant une glycémie supérieure à 2 g/1 sont traités, par voie orale, par gavage à l'aide d'une sonde gastrique, par une dose unique soit de deoxyfructosazine seule (5-50-100-150 mg/kg) ou de metformin seul (100-200 mg/kg) ou d'une association deoxyfructosazine et metformin. Un groupe d'animaux ne reçoit que le véhicule. Les taux de glycémie sont mesurés à 30 minutes, 1 heure puis toutes les heures pendant 8 heures après le traitement par les produits.Male Wistar rats weighing 180 to 200 g are made diabetic by intravenous injection of 60 mg / kg of streptozotocin. After 72 hours, the blood sugar of the animals is measured on the glucometer. Animals with a blood sugar lower than 2 g / 1 are not selected for the study and those with a blood sugar higher than 2 g / 1 are treated, orally, by gavage using a gastric tube, with a single dose of either deoxyfructosazine alone (5-50-100-150 mg / kg) or metformin alone (100-200 mg / kg) or a combination of deoxyfructosazine and metformin. A group of animals receives only the vehicle. Blood sugar levels are measured at 30 minutes, 1 hour and then every hour for 8 hours after treatment with the products.
B - activité en dose répétée, chez le rat traité à la streptozotocineB - repeated dose activity in rats treated with streptozotocin
Des rats Wistar mâles pesant 180 à 200 g sont rendus diabétiques par injection intraveineuse de 60 mg/kg de streptozotocine. Au bout de 72 heures, la glycémie des animaux est mesurée au glucomètre. Les animaux dont la glycémie est inférieure à 2 g/1 ne sont pas retenus pour l'étude, ceux présentant une glycémie supérieure à 2 g/1 sont traités, par voie orale, par gavage à l'aide d'une sonde gastrique, par une dose par jour pendant 30 jours soit de deoxyfructosazine seule (5-50-100-150 mg/kg) ou de metformin seul (100-200 mg/kg) ou d'une association deoxyfructosazine et metformin. Un groupe d'animaux ne reçoit que le véhicule. Les taux de glycémie sont mesurés 1 fois par jour.Male Wistar rats weighing 180 to 200 g are made diabetic by intravenous injection of 60 mg / kg of streptozotocin. After 72 hours, the blood sugar of the animals is measured on the glucometer. Animals with blood sugar below 2 g / 1 are not considered for the study, those with a blood sugar level higher than 2 g / 1 are treated, orally, by gavage using a gastric tube, by a dose per day for 30 days. either deoxyfructosazine alone (5-50-100-150 mg / kg) or metformin alone (100-200 mg / kg) or a combination of deoxyfructosazine and metformin. A group of animals receives only the vehicle. Blood sugar levels are measured once a day.
Les résultats obtenus dans les tests A et B démontrent que, chez les animaux recevant l'association, les taux de glycémie sont nettement inférieurs à ceux des animaux témoins et à ceux des animaux traités par un seul antidiabétique.The results obtained in tests A and B demonstrate that, in the animals receiving the association, the blood sugar levels are much lower than those of the control animals and those of the animals treated with a single antidiabetic.
C - activité préventive chez la souris élevée à MadagascarC - preventive activity in mice raised in Madagascar
A des souris élevées à Madagascar, on donne par voie orale par gavage pendant 4 jours soit la deoxyfructosazine seule (5-50-100-150 mg/kg) ou le metformin seul (100- 200 mg/kg) ou une association deoxyfructosazine et metformin. Trois heures après le dernier traitement, on donne par voie orale 2 g/kg d'une solution aqueuse de glucose. Les concentrations de glucose dans le sang sont déterminées, 20 minutes plus tard, au moyen d'un glucomètre.Mice raised in Madagascar are given orally by gavage for 4 days either deoxyfructosazine alone (5-50-100-150 mg / kg) or metformin alone (100-200 mg / kg) or a combination of deoxyfructosazine and metformin. Three hours after the last treatment, 2 g / kg of an aqueous glucose solution are given orally. Blood glucose levels are determined 20 minutes later using a glucometer.
Dans ce test, les résultats obtenus démontrent que, chez les animaux recevant l'association, l'accroissement de la concentration de glucose sanguin est nettement diminué par rapport à celui des animaux non traités et à celui des animaux traités par un seul antidiabétique.In this test, the results obtained demonstrate that, in the animals receiving the combination, the increase in the blood glucose concentration is markedly reduced compared with that of the untreated animals and that of the animals treated with a single antidiabetic.
D - activité chez le rat Zucker (fa fa)D - activity in the Zucker rat (fa fa)
Des rats obèses Zucker (fa/fa) âgés de 5-6 semaines sont traités, par voie orale, en un seul gavage, pendant 7 et 14 jours par la deoxyfructosazine seule (5-50-100- 150 mg/jour/kg) ou le metformin seul (100-200 mg/kg) ou par une association de deoxyfructosazine et metformin. Les groupes contrôles sont gavés dans les mêmes conditions avec l'excipient seul. La prise alimentaire et le poids des animaux sont mesurés chaque jour au cours de l'expérience. Au bout de 7 et 14 jours, les rats sont anesthésiés au pentobarbital. Un test de tolérance au glucose (0,5g/kg) est effectué par voie intraveineuse et des échantillons de sang sont prélevés 5, 10, 15, 20, 25 et 30 minutes après l'injection afin de mesurer la glycémie et l'insulinémie.Obese Zucker (fa / fa) rats aged 5-6 weeks are treated, orally, in a single gavage, for 7 and 14 days with deoxyfructosazine alone (5-50-100- 150 mg / day / kg) or metformin alone (100-200 mg / kg) or by a combination of deoxyfructosazine and metformin. The control groups are force-fed under the same conditions with the excipient alone. The food intake and the weight of the animals are measured every day during the experiment. After 7 and 14 days, the rats are anesthetized with pentobarbital. A glucose tolerance test (0.5 g / kg) is carried out intravenously and blood samples are taken 5, 10, 15, 20, 25 and 30 minutes after the injection in order to measure blood sugar and insulinemia .
Les résultats obtenus dans ce test démontrent que, chez les animaux recevant l'association, les réponses au test de tolérance au glucose sont nettement inférieures à celles des animaux témoins et à celles des animaux traités par un seul antidiabétique.The results obtained in this test demonstrate that, in the animals receiving the combination, the responses to the glucose tolerance test are much lower than those of the control animals and those of the animals treated with a single antidiabetic.
