C) Determination of the antiulcer activity The technique utilised, is described by SHAY et al in Gastroenterology, 5, 43 (1945).
The SHAY technique consists o£ inducing ulcers at the level of the stomach,ia rats, by ligature from the pylorus.
The animals are anaesthetized with ether. A longitudinal incision is made about 1 cm below the sternum, the glandular part of the stomach and the duodenum is opened up and a ligature is placed; a few millimeters, below the pylorus.' The muscular plan is left as it is and the skin is sutured with two clips? Immediately afterwards the animals receive dispersive or the substance under study, by oral route, at a volume of 0.5 ml/100 g and they are kept without food or drink until they are killed by carotidian bleeding which takes place about 16 hours after the treatment.
Before the stomach is removed, a ligature is placed above the cardia.
The gastric liquid is collected in order to measure its pH.
The stomach is then opened along the large curvature, rinsed in physiological serum and stretched out on millimetric paper so as to be examined under a binocular magnifier. 542G2 - 38 The extent of the lesions is evaluated macroscopically and rated at 0 to 4 for each stomach.
For each group of rats, the mean intensity of the ulcerations are determined and the protection is calculated as a ratio of the means index of the group to the mean index of the control group.
The value of pH of the gastric liquid is also determined for the animals treated and the control animals.
The following results were obtained; Product of the Example Hose (mg/kg) pH of the gastric liquid % Protection of 1 ulceration in relation to the controls animals treated control animals 5 2 2.6 2 90% 0.4 2.5 2.2 60% 0.08 2.6 2.2 66% 11 5 2.9 3.0 63% 1 3.2 3..3 48% D) Study of the acute toxicity The lethal doses LDq of the different compounds tested was evaluated after administration by oral route to mice.
