Biodistribuição do pertecnetato de sódio (Na99mTcO4) em ratos submetidos à ressecção extensa de intestino delgado

Massive resection of the small intestine results in short bowel syndrome with anti-absorptive effect and repercussions on the metabolism. Morphologic and functional evaluation may be necessary in order to control wrapped organs. Scintigraphy an examination with little invading and no biologic damage can be used. The purpose were to assess the biodistribution of sodium pertecnetate in organs of rats subjected to massive resection of the small intestine, the intestinal adaptation of the remnant intestinal mucosa and weight curve evaluation in the postoperative period. Twenty-one Wistar rats were randomly allocated into three groups (n = 7). The operated group named short bowel (SB) after anesthetized was subjected to massive resection of the small intestine; the control group (C), and sham group (SHAM). On the 30th postoperative day, 0.l mL of sodium pertechnetate was injected into the venous orbital plexus. After 30 minutes, the rats were killed with an overdose of anesthetic, and fragments of the liver, spleen, pancreas, stomach, duodenum, small intestine, thyroid, lung, heart, kidney, bladder, muscle, femur and brain were harvested. The percentage of radioactivity per gram of tissue (%ATI/g) was determined using Gama Counter WizardTM 1470, PerkinElmer to all samples. Biopsies of 3 cm remaining jejunum were removed to histological analyses. Analysis of variance (ANOVA) and the Tukey test for multiple comparisons were used, considering p<0.05 as significant. The study had the participation of some departments and laboratories, as Nucleus of Experimental Surgery, Department of Surgery, Laboratory of Radiobiology, Department of Pathology and Service of Nuclear Medicine, certifying the character of a multidisciplinary research. The results were no significant differences in %ATI/g of the sodium pertechnetate in the organs of the groups studied (p>0.05). An increase in the weight of the SB rats was observed after the second postoperative week. The jejunal mucosal thickness of the SB rats was significantly greater than that of C and sham rats (p<0.05. The biodistribution of sodium pertechnetate was not affected by massive intestinal resection in rats. An adaptive response by the intestinal mucosa probably contributed to the reversion of weight loss and the biodistribution of sodium pertechnetate was not affected by the surgery

A luta do Bispo Dom José de Medeiros Delgado por educação escolar para todos (Caicó-RN, 1941-1951)

The socioeducational program of actions developed by Dom José de Medeiros Delgado, first Bishop of Diocese of Caicó city in Rio Grande do Norte, from 1941 to 1951, is analyzed by the present work in a historical perspective, based upon the school culture refecence.Through this reference point, the general and peculiar school culture proper of catholic schools founded by Dom Delgado was learned.The schools are: the Ginásio Diocesano Seridoense (1942), the Escola Doméstica Popular Darci Vargas (1943, the Prevocacional School of Caicó (1944) and the Santo Cura d ars Seminar (1946). The socioeducational actions of Dom Delgado Bishop affected seven other towns surrounding Caicó. Places where catholic schools were founded and named after Escola do Pobre . In fight for schools for all social segments of city and rural natures, Dom Delgado founded four rural schools in the surroundings of Serra Negra, São João do Sabugi, Jardim do Seridó e Lagoa Nova. It is also part of his beneficial work the creation of rural cooperatives for the parents of the students from such schools

Grupo Escolar Duque de Caxias festas escolares: uma celebração de múltiplos significados - 1949 1962

El trabajo que aquí se presenta tuvo como objetivo investigar una institución escolar en la ciudad de Macau / RN. Esta institución, que fue innovadora en su contexto social y pedagógico, fue pesquisada a la luz de los parámetros de la historia cultural. Una escuela que fue creada en el siglo XX, en el año de 1923, cuando el país aún vivía la efervescencia de la implantación del nuevo ordenamiento político - la República. Elegimos como objeto de estudio las fiestas escolares, que tuvo lugar en esta institución durante el periodo 1949-1962, procurando aclarar cómo ocurría la realización de estas fiestas y cómo fueron fundamentales para el funcionamiento de las relaciones políticas, sociales y culturales en el ámbito escolar. El análisis y la interpretación de las fuentes documentales escolares, los documentos de otras instituciones, las entrevistas abiertas, la información oral, la legislación de la educación y de las escuelas, los periódicos y documentos oficiales de la época relacionados con la temática y que formaron el corpus documental, se basaron por obras de Souza (1998), Juliá (2001), Castro (1997), Kossoy (2001) Saviani (2005), Escolano (1992) y Carvalho (1990). Por tratarse de una institución de enseñanza, el análisis central es la cultura escolar y la historia de la educación brasileña es el campo de la investigación, haciendo una relación de las fiestas escolares. En el relato, se reconstituyen las festividades cívicas, solemnes y recreativas, además de los elementos de formación que se evidencian en el discurso de la educación moderna. Para ello, buscamos entender que, en las prácticas cotidianas de la escuela, había un método de actuación que seguía las directrices del Departamento de Educación. Estas directrices eran dadas por medio de las normas y decretos editados y se adentraban en el discurso en torno de las iniciativas emprendidas para difundir las nuevas prácticas pedagógicas, y dentro de ellas, en el momento apropiado, los profesores dedicaban un tiempo de sus clases para explicar acerca de los días festivos y sus organizaciones. Estas constataciones fueron certificadas por la documentación listada y por las entrevistas abiertas, y nos señaló para el modelo escolar propugnado por el Grupo Escolar Duque de Caxias, que era fruto del nuevo orden republicano

O eterno espanto: uma leitura estética em Mario Quintana

This work aims to read the phenomenon of the Sublime as the main aesthetical concern in the work of the Brazilian poet Mario Quintana. The research was based on the dialogical approach used by Mario Quintana to see life & poetry. This search noticed that such aesthetical concern is an answer to the modern age that surrounds the post-war man. Immerse in his aesthetical concerns, Mario Quintana designs, through his poetry, a way to give humanity back to men. In this attempt of rupture, Mario Quintana returns to tradition through astonishment besides laughter
