A morphometric study of the intestinal mucosa of rats submitted to omentoenteropexy.

Context: The omentoenteropexy technique was developed as an alternative method for intestinal neovascularization, due to the angiogenic properties of factors from the omentum.

Objectives: This study investigated changes in intestinal villi heights and crypts depths due to surgical techniques: seromiotomy with and without omentoenteropexy.

Method: Thirty rats were operated on, after being divided into three groups, namely GI, GII and GIII with 10 rats each.

Heparanase-2, syndecan-1, and extracellular matrix remodeling in colorectal carcinoma.

Aim: To propose a quantitative method to detect heparanase-2 (HPA2) and syndecan-1 (Syn-1) using immunohistochemistry in colorectal (colon and rectal) carcinomas compared with nonneoplastic tissues and evaluate the possible role of these molecules in tumor development and extracellular remodeling.

Methods: Cytoplasmic staining of HPA2 and Syn-1 was obtained by standard immunohistochemical reactions in 50 colorectal carcinoma and 20 nonneoplastic large bowels tissues. An image system was used to quantify the immunoexpression by digital computer-assisted method (Matos et al.

[Reflux esophagitis in children: histological and morphometric study].

Background: Gastroesophageal reflux disease is a frequent cause of morbidity in childhood, including esophagitis and recurrent respiratory symptoms; however histological and morphometric studies in esophageal biopsies of children are scarce.

Aim: To study histological and morphometric findings in children with reflux esophagitis.

Patients And Methods: We studied 26 esophageal biopsies of children (mean age: 4.
