DOENÇA INTERSTICIAL PULMONAR ASSOCIADA À DOENÇA INFLAMATÓRIA INTESTINAL: RELATO DE DOIS CASOS

The lung involvement in the inflammatory bowel disease is rare and it is not well characterized. We describe two cases of female patients with unspecific pulmonary symptomatology, and previous treatment for inflammatory bowel disease - Crohn‘s disease (case 1) and ulcerative rectocolitis. A chest computerized tomography was compatible with usual interstitial pneumonia (UIP). Related literature was reviewed.O acometimento pulmonar na doença inflamatória intestinal é raro e não está bem caracterizado. Relatamos os casos de duas pacientes com sintomatologia pulmonar inespecífica, em tratamento prévio de doença inflamatória intestinal – doença de Crohn (caso 1) e retocolite ulcerativa (caso 2). Os achados tomográficos foram compatíveis com pneumonia intersticial usual (PIU). Foi realizada revisão da literatura sobre o assunto

Phytosociology of a permanent preservation area in east of Amazon: indication of species for recovering altered areas.

This paper presents the phytosociology of a fragment of a dense ombrophilic forest with 84ha in Northeastern Pará state in trees with DBH ³ 20cm. The species were classified in ecological groups in function of light demand and commercial use. The sampling was composed by 12 random 1ha plots and divided in 100 subplots of 10m ´ 10m. It was recorded 2,326 individuals in 158 species, 107 genera and, 43 families. The families Fabaceae and Lecythidaceae had the highest richness and density in the floristic composition of the area. The first family presents the highest number of species (41) and the second, the highest number of individuals (609), and both of them present high dominance and frequency. As regards to the ecological groups, the species shade tolerant were majority (63.29 %) while in the economic use, the commercial species predominated (41.15 %). It suggests that species with high ecological importance and commercial interest be used for altered area recovering. Around sampled species, some of them are most important such as Pouteria heterosepala, Eschweilera amazonica, Eschweilera blanchetiana, Protium apiculatum, Guatteria poeppigiana, Sterculia pilosa, Inga brevialata and Licania heteromorpha. However, before any kind of investment it must get safe informations about ecology and silviculture of these species.Neste artigo é apresentada a fitossociologia de um fragmento de Floresta Ombrófila Densa de 84 ha no nordeste do estado do Pará, com árvores de DAP ³ 20 cm. As espécies foram classificadas em grupos ecológicos em função das exigências de luz e quanto ao uso comercial. Os dados foram coletados em 12 parcelas de 1 ha aleatorizadas e subdivididas em 100 subparcelas de 10´10 m. Foram registrados 2.326 indivíduos distribuídos em 158 espécies, 107 gêneros e 43 famílias. As famílias Fabaceae e Lecythidaceae tiveram a maior riqueza e densidade na composição florística da área. A primeira apresentou o maior número de espécies (41), a segunda, o maior número de indivíduos (609), e ambas apresentaram alta dominância e freqüência. Quanto aos grupos ecológicos, as espécies tolerantes foram maioria (63,29 %); quando considerada a classificação quanto ao uso econômico, as espécies comerciais predominaram (41,15 %). Sugere-se que espécies com alta importância ecológica e interesse comercial sejam utilizadas para a recuperação de áreas alteradas. Entres as espécies encontradas, destacaram-se Pouteria heterosepala, Eschweilera amazonica, Eschweilera blanchetiana, Protium apiculatum, Guatteria poeppigiana, Sterculia pilosa, Inga brevialata e Licania heteromorpha. Entretanto, antes de qualquer ação empreendedora, devem-se obter informações seguras sobre a ecologia e a silvicultura dessas espécies

Construction and calibration of Time Domain Reflectometry probes for assessing soil humidity in distropheric red latosol

Among the indirect methods of assessing soil moisture, Time Domain Reflectometry (TDR) stands out, which uses the soil dielectric constant to provide volumetric moisture efficiently, quickly and non-destructively. Despite a practical and precise method, TDR has a high cost due to the probes and its Data Logger. In view of this, the present work aims to build and calibrate TDR probes to assess moisture in a Dystrophic Red Latosol. The present work was carried out in the experimental area of the hydraulics laboratory of the Federal University of Grande Dourados (UFGD), located in Dourados-MS, at latitude 22⁰ 12 \u27south, longitude 54⁰ 59\u27 west and altitude of 434 meters. Each probe built consisted of 3 stainless steel rods (Ø = 3 mm; L = 230 mm) RG 98 cable with 90% mesh and 50 ohm impedance, 4.7 pF ceramic capacitor and BNC connector. The construction procedures followed the following steps: 1- Making the cable, 2- Preparing the rods, 3- Welding the rods to the wires, 4 -Operating test and 5 - finishing phase. After construction, they were calibrated with the characteristic soil of the Region, proceeding with the Probe Reading in two depths (10 and 30 cm) and simultaneous collection of deformed soil samples to determine the moisture based on mass in Laboratory. Subsequently, calibrations with cubic polynomial adjustment were performed. The results showed adjustments with high determination coefficients, and the probes developed showed satisfactory performances
