RESUMEN
Basal and stimulated (after a standard meal) serum gastrin was determined by means of the radioimmunoassay method in 27 patients with epigastric pain that could not be diagnosed in the outpatient departement. An individual study of the patients with high (up to 300 pg/ml) basal and stimulated serum gastrin levels showed that most gastroduodenal diseases are situated within this range while levels of 500 pg/ml suggest Zollinger-Ellison syndrome. The test of serum gastrin stimulated with a standard protein-rich meal was proved more valuable than the basal one. Further investigations would be necessary to demonstrate the value of this test in the diagnosis of gastroduodenal ulcer, gastrites or gastric cancer.

Forty adult patients having intestinal infestation with giardia or with parasitic associations, such as giardia-strongiloides, giardia-taenia solium, were subjected to morphological explorations, iron and vitamin B12 absorption tests, steatorrhea assay and serological tests, before treatment as well as six months and one year after eradication of the infection. On admittance, jejunal morphological lesions were noted only in 15 cases especially in associated infestation, iron depletion in six patients, vitamin B12 malabsorption in five patients and steatorrhea only in two cases. After the lapse of six months and one year, respectively, all the tests ranged within normal values, and the jejunal morphological aspect improved significantly indicating the pathogenetic role of intestinal parasites in the development of selective malabsorption.
