RÉSUMÉ
The objective of this experiment was to evaluate the influence of Gln and vitamin E (VE) supplementation in the diet of broiler chickens (Cobb-Vantress) on the morphometry of the intestinal mucosa. The design was completely randomized in a 2 x 3 (VE x periods of administering Gln) factorial arrangement. The levels of VE used were 10 and 500 mg/kg of diet and 3 periods of administering (1%) Gln-supplemented starter diet (for the first 7 or 14 d of life or for no added Gln), totaling 6 treatments with 5 replicates of 50 birds per experimental unit. In the growth period (d 22 to 41 posthatch), the treatments consisted only in the respective levels of VE. On d 7, 14, 21, and 41 posthatch, 2 birds per replicate were killed, and samples of the duodenum, jejunum, and ileum were subsequently removed, fixed in Bouin solution, and later embedded in paraffin and stained with hematoxylin-eosin. The parameters analyzed were villus height and crypt depth. An ANOVA was applied to the obtained data, and the means were compared using Tukey's test (5% significance level). Greater development was observed in the duodenum, followed by the jejunum and ileum. On 41 d of life, diets with 10 mg of VE/kg supplemented with Gln (for the first 7 d of life) provided better development of the intestinal mucosa in broiler chickens.

La endometriosis apendicular tiene una frecuencia menor de 1 por ciento de las endometriosis pelvicas. Su diagnostico en la mayor parte de las ocasiones es incidental. Se informa un caso de endometriosis apendicular en una mujer en la cuarta decada de la vida, con antecedentes de esterilidad primaria, que ingreso con cuadro doloroso abdominal en cuadrante inferior derecho sin otros datos clinicos, radiologicos e do laboratorio que sugirieran el diagnostico. Se intervino con diagnostico preoperatorio de apendicitis aguda y se el realizo apendicectomia. El estudio histopatologico demostro focos endometrioides en la serosa apendicular sin datos de apendicitis aguda. La endometriosis debe considerarse entre las posibilidades diagnosticas en mujeres con cuadros "apendiculares" en los dias premenstruales y menstruales
