Quantitative analysis of mast cells in the stomach. Data represent the mean ± S.E.M of sixty fields analyzed per animal as described in Material and Methods. Non-denervated (I) and denervated stomach (II) without lesions. Non-denervated (III) and denervated stomach (IV) with lesions. Non-malignant tumor (NT). Malignant tumor (MT). A) Total number of mast cells in the gastric fragment. *P < 0.05 vs. group I. # P < 0.01 vs. another experimental groups. B and C) Intact and degranulated mast cells in the mucosal, submucosal and muscular layers. * P < 0.05 vs. group I; #P < 0.05 vs. another experimental groups; δ P < 0.05 vs. group III - NT (intact mast cells); &P < 0.05 vs. group III - NT (degranulated mast cells). C) Intact and degranulated mast cells in the muscular layer. *P < 0.05 vs. group I; # P < 0.05 vs. group II.
