From a sample of 70 selected after gastric biopsies and who presented no gastroduodenal illness was proposed a table of reference of values of gastric acid secretion in Senegalese in their base state and after stimulation with a subcutaneous injection of 6 microgrammes per kilo of pentagastrine. The method of calculation is taken entirely from the one proposed by Bernier and colleagues (1973). The flow (or hourly volume) found in the sample are established in comparison with the thin mass and more precisely with the exchangeable potassium that was obtained in relation to the weight, age and sex. The comparison with European's secretion shows differences statistically significant for stimulated secretion. The hourly volume (average and standard deviation) are calculated for all subject in relation to the weight, age and sex.
