Resumo: 	Scientific literature, although limited in this area, supports the hypothesis that asthma, by means of selective leukocyte trafficking between the various mucosal and glandular sites of the body, can have the same pathophysiological effects on the stomach as the airways. This study aimed to determine if asthma, in the absence and presence of various asthma therapies (Hydrocortisone and Modul8TM), imparted any morphological alteration on the stomach parietal and chief cells. The BALB/c murine asthmatic mouse model was the model of choice in this study. The asthma induction protocol as well as the asthma therapies were proved to be effective with the aid of bronchial lavage fluid leukocyte quantification. Fundic and pyloric biopsies were extracted at termination and assessed by means of transmission electron, scanning electron and light microscopy. The extracted fundic and pyloric biopsies revealed asthma alone induced parietal cell hypertrophy (increase in parietal cell size P &lt; 0.000100 in both stomach regions) and chief cell hyper functioning. The use of Hydrocortisone and Modul8TM, as a therapy to correct the perceived gastric alterations were dismal; only in the case of fundic parietal cells were both treatments able to compensate for the hypertrophic effect caused by asthma, while in the pylorus parietal cell asthma- induced hypertrophy was only compensated for by Modul8TM.
