Effects of myenteric denervation on extracellular matrix fibers and mast cell distribution in normal stomach and gastric lesions

Table 1 Stereological evaluation of the effects of myenteric denervation in the gastric antrum.

	Relative frequency distribution of the fibers(%)¹
Groups	Collagen System	Elastic System
I	16.87 ± 0.5	13.27 ± 0.5
II	24.06 ± 1.5*	19.4 ± 0.6*
III - NT	21.8 ± 0.9	11.2 ± 0.6
III - MT	25.71 ± 0.5*	11.1 ± 0.4
IV - NT	21.2 ± 1.6	20.2 ± 1.7^&
IV - MT	26.87 ± 1.5*	19 ± 0.7^&

Histological preparation was performed as described in Materials and Methods. Values are expressed as mean ± SEM of percentage of relative frequency of fibers. Non-malign tumor (NT); malign tumor (MT). ¹ Statistical analysis based on ANOVA followed by the correction of Tukey-Kramer. *P < 0.05 vs. group I; ^&P < 0.05 vs. group III.
