RESUMO
Rabbit peritoneum was studied by SEM to obtain information and statistically meaningful morphometric data of different sites of visceral and parietal peritoneum and to verify the existence of "stomata." Samples were fixed by intraperitoneal infusion of glutaraldehyde, and were photographed by SEM under standard conditions. Morphometric data were obtained by Kontron MOP Videoplan. Variable cell surface patterns were present even within limited areas; however, "stomata" were not observed. The heterogeneity of data obtained can be related to the dynamism of mesothelial cell activity and to the different motilities of the underlying organs.

On the basis of the concepts presented in Note I, the effects of excluding the duodenum from the digestive circuit are examined. In practice, the effects are reflected in disturbances to intestinal canalization with consequent post-prandial syndromes, and to the digestion and absorption of foods (deficiency syndromes). Over and above histological, biological and biochemical findings, the severe pathology affecting the entire digestive function brought on by the elimination of the manifold, complex activities of the "duodenal laboratory" were confirmed clinically.
