title: [Assessment of th- quantity of mast cells in the organs of the gastrointestinal tract of rats and frogs].
abstract: A method of evaluation of mast cell concentration in which all the tissues of an organ are included gives statistically significant figures. This method showed mast cell concentration in the digestive tract organs of rats and frogs to be a fixed value within a morphofunctional zone. In the tongue the mast cell concentration was the same both along its length and in the symmetrical parts of the organ. The concentration of mast cells diminished considerably from the tongue, the duodenum and down to the stomach.
