Abstract: Com este estudo objetivou-se avaliar a massa seca de forragem e laminas foliares, ganho médio diário, taxa de lota o e ganho de peso vivo em capim-tanzania (Panicum maximum Jacq.) no período de novembro de 2008 a julho de 2009 sob lota o contínua. Utilizou-se delineamento experimental em blocos ao acaso em parcela subdivididas, com três repeti es, e como tratamentos: Tanzania + Estilosantes Campo Grande; Tanzania + 75kg/ha de N; Tanzania + 150kg/ha de N e Tanzania + 225kg/ha de N, e nas sub-parcelas os períodos do ano: primavera, ver o e outono. No ver o, a massa seca de forragem e laminas foliares foram superiores à primavera e outono. O tratamento com 225kg de N apresentou maior massa seca de forragem e massa seca de laminas foliares no ver o e outono. Obteve-se maior ganho médio diário no ver o. Na primavera e no ver o n o houve diferen a entre os tratamentos para o ganho médio diário, e no outono o tratamento com 225kg/ha de N foi superior. A taxa de lota o foi semelhante no ver o e outono, e menor na primavera. O tratamento com 225kg de N apresentou maior taxa de lota o na primavera e ver o. O tratamento com 225kg de N apresentou maior ganho de peso vivo no outono, na primavera e ver o o 150 kg de N foi semelhante. A disponibilidade de massa seca de forragem e o desempenho animal proporcionado pelo Estilosantes foram equivalentes à aduba o nitrogenada até a dose de 75kg de N. This study aimed to evaluate the dry mass of forage and leaf blade dry mass, average daily gain, stocking rate and live weight gain in Tanzania grass (Panicum maximum Jacq.) from November/2008 to July/2009, on continuous stocking. The experimental design was a split-plot arrangement in a randomized blocks design, with three replications and four treatments: Tanzania + Campo Grande Stylo; Tanzania + 75kg/ha of N; Tanzania + 150kg/ha of N and Tanzania + 225kg/ha of N, subplots were the seasons of the year: Spring, Summer and Autumn. The forage dry mass and leaf blade dry mass was higher in Summer compared to Spring and Autumn. The treatment with 225kg of N presented higher dry mass of forage and leaf blade dry mass in Summer and Autumn. It was obtained the higher average daily gain in the Summer. In the Spring and Summer no differences were observed for average daily gain, but in the Autumn the treatment with 225kg/ha of N was the best. The stocking rate was similar in Summer and Autumn, but lower in Spring. The treatment with 225kg of N presented the higher stocking rate in Spring and Summer. The treatment with 225kg of N presented the higher live weight gain in Autumn, w

Arquivos de Gastroenterologia , 2001,
Abstract: Background - Patients who underwent partial gastric resections are at an increased risk for the development of cancer in the gastric remnant. Aim - To assess the long-term patients who underwent surgical treatment for peptic ulcer disease through endoscopic and pathologic evaluation of the gastric stump mucosal alterations. Patients and Methods - Between 1987 and 1990, 154 patients (mean = 20.4 years after gastrectomy) were evaluated by upper digestive endoscopy with multiple biopsies and pathological examination. Results - Endoscopic alterations were present in 111 patients (72.1%). The commonest pathologic alterations were foveolar hyperplasia, intestinal metaplasia and cystic dilation. Severe dysplasia was noted in two (1.25%) and carcinoma in 13 (8.4%) of the cases. In four patients (3.8%) the endoscopic findings did not show any evidence of tumors, however they were detected due to multiple biopsies and histologic studies. Conclusions - Surveillance of these patients with endoscopy and multiple biopsies may provide the means to diagnose tumors at an early stage, but the cost benefit ratio of surveillance requires further study.

Abstract: Isolated splenic metastasis from lung cancer is an exceedingly rare event. Here, we present the case of an 82-year-old male with previously excised lung squamous cell carcinoma who developed local recurrence and a splenic metastasis. This is only the 17th known report of isolated splenic metastasis, including English and non-English literature.In April 2006, an 82-year-old former smoker male was investigated due to persistent cough. A Computed Tomographic (CT) scan of the chest showed a 2.2 × 1.5 cm nodule in the right mid-lung. Bronchoscopic biopsies revealed a moderately differentiated Squamous cell carcinoma (Figure 1). Preoperative investigation showed no mediastinal lymphadenopathy or distant metastatic disease.The patient underwent a right bilobectomy confirming a moderately differentiated squamous cell carcinoma with large polygonal cells, keratinization, intercellular bridges and keratin pearls (pT2pN2). As margins were scanty, adjuvant chemo-radiation was indicated (4 cycles of Carboplatin and Paclitaxel and 50 Gy). Patient remained asymptomatic and sixteen months after surgery a CT scan revealed a 1 × 1 cm cystic lesion in the spleen (Figure 2). Follow-up was lost and a new CT scan was only performed one year later. This exam revealed an interlobular thickening and an enlargement of the splenic lesion now measuring 6.5 × 6.4 cm (Figure 2). The patient was then referred to palliative chemotherapy with Gemcitabine and received 4 cycles (3 of them with reduced dose due to mielotoxicity). A new CT scan showed stability of the pulmonary disease but progress of the splenic lesion (7.8 × 7.8 cm - Figure 2). Splenectomy was then indicated. During preoperative period the patient presented an acute bowel obstruction. A CT scan of the abdomen and pelvis showed an abrupt obstrutive point at the level of the left colon and the patient underwent an urgent laparotomy. Surgical findings consisted of the large splenic lesion without invasion of adjacent structures and a le

Abstract: RACIONAL: A literatura oriental é notável por apresentar taxas de sobrevida para o tratamento cirúrgico do adenocarcinoma gástrico superiores àquelas apresentadas nos países ocidentais. OBJETIVO: Analisar o resultado a longo prazo após a gastrectomia D2 por cancer gástrico. MéTODOS: Duzentos e setenta e quatro pacientes foram submetidos à gastrectomia com dissec o linfonodal D2 como tratamento exclusivo. Os critérios de inclus o foram: 1) remo o dos linfonodos de acordo com dissec o linfática padronizada Japonesa, 2) opera o potencialmente curativa descrita no prontuário como dissec o D2 ou mais linfonodos; 3) invas o tumoral da parede gástrica restrita ao órg o (T1-T3); 4) ausência de metástases à distancia (N0-N2/M0); 5) mínimo de cinco anos de acompanhamento. Dados clinicopatológicos incluíam sexo, idade, localiza o do tumor, classifica o de Borrmann do tumor macroscópico, o tipo de gastrectomia, as taxas de mortalidade, tipo histológico, classifica o e estadiamento TNM de acordo com a UICC TNM 1997. RESULTADOS: Gastrectomia total foi realizada em 77 casos (28,1%) e subtotal em 197 (71,9%). O tumor foi localizado no ter o superior em 28 casos (10,2%), no ter o médio em 53 (19,3%), e no ter o inferior em 182 (66,5%). Borrmann foi atribuído cinco casos (1,8%) como BI, 34 (12,4%) BII, 230 (84,0%) BIII e 16 (5,9%) BIV. Os tumores foram histologicamente classificados como Laurén tipo intestinal em 119 casos (43,4%) e como o tipo difuso em 155 (56,6%). De acordo com a UICC TNM foram cancer gástrico precoce (T1) foi diagnosticada em 68 casos (24,8%); 51 (18,6%) T2 e 155 (56,6%) T3. Nenhum envolvimento linfonodal (N0) foi observado em 129 casos (47,1%), enquanto 100 (36,5%) eram N1 (1-6 linfonodos) e 45 (16,4%) N2 (7-15 ganglios linfáticos). O número médio de linfonodos dissecados foi de 35. A sobrevida em cinco anos para os estádios de I a III B foi de 70,4%. CONCLUS O: Cirurgi es digestivos devem ser estimulados a realizarem gastrectomias D2 para n o deixar de lado o único tratamento para adenocarcinoma gástrico que provou ser eficiente os dias atuais. Deve ser enfatizado que a padroniza o da dissec o linfática de acordo com a localiza o do tumor é mais importante do que apenas o número de ganglios removidos BACKGROUND: Eastern literature is remarkable for presenting survival rates for surgical treatment of gastric adenocarcinoma superior to those presented in western countries. AIM: To analyze the long-term result after D2 gastrectomy for gastric cancer. METHODS: Two hundred seventy four underwent gastrectomy with D2 lymph node dissection as exc

Abstract: The aim of this study was to evaluate the non-structural carbohydrates and root biomass in pastures of Coastcross + Arachis pintoi; Coastcross + Arachis pintoi with 100kg/ha of nitrogen (N); Coastcross + Arachis pintoi with 200kg/ha of N; and Coastcross with 200kg/ha of N, in the seasons of winter, spring, summer and autumn. In the experimental was used a complete randomized block design with subdivided parcels, with two repetitions (blocks) was used. The use of nitrogen fertilization (100kg/ha) associated to the Arachis pintoi provided the highest content of non-structural carbohydrates (0,3942g/hg) in the roots and greater root biomass (0,4483kg/m3). The content of non-structural carbohydrates and the root biomass were higher in the summer and autumn. The concentration of 63%, 24 % and 13% of the root biomass occurred in the layer of 0 - 15; 15 - 30 and 30 - 45cm of the ground, however, it did not have difference in the root biomass between the treatments with or without intercropping, in the studied depths. The concentrations of the non-structural carbohydrates were similar in the different depths of the root. Objetivou-se neste trabalho avaliar a concentra o de carboidrato n o-estrutural e biomassa radicular em pastagens de grama Coastcross + Arachis pintoi; Coastcross + Arachis pintoi com 100kg/ha de nitrogênio (N); Coastcross + Arachis pintoi com 200kg/ha de N; e Coastcross com 200kg/ha de N, nos períodos de ver o, outono e inverno. Utilizou-se delineamento experimental em blocos ao acaso com os tratamentos em esquema de parcelas subdivididas, com duas repeti es (blocos). A utiliza o de aduba o nitrogenada (100kg/ha) associada ao Arachis pintoi proporcionou maior concentra o de carboidrato n o estrutural (0,3942g/hg) na raiz e maior biomassa radicular (0,4483kg/m3). A concentra o de carboidrato n o estrutural e a biomassa radicular foram elevadas no ver o e outono. A concentra o de biomassa radicular foi de 63%, 24% e 13% nas profundidades de 0 - 15, 15 - 30 e 30 - 45cm, entretanto, n o houve diferen a na biomassa radicular entre os tratamentos com e sem consorcia o, nas profundidades estudadas. As concentra es de carboidratos n o estruturais foram semelhantes nas diferentes profundidades das raízes.

Abstract: O estudo objetivou avaliar a produ o de forragem e desempenho animal em pastagens de Coastcross + Arachis pintoi; Coastcross + Arachis pintoi com 100 kg ha-1 de N; Coastcross + Arachis pintoi com 200 kg ha-1 de N e Coastcross com 200 kg ha-1 de N, nas esta es de inverno, primavera, ver o e outono. Utilizou-se o delineamento experimentalem blocos ao acaso, com os tratamentos em parcelas subdivididas, com duas repeti es. Foram avaliados: acúmulo de massa de forragem e acúmulo diário de massa de forragem, ganho médio diário (GMD), ganho de peso vivo por área e taxa de lota o. A utiliza o de Coastcross + 200 kg ha-1 de N e as melhores condi es climáticas na primavera e ver o favoreceram tanto o acúmulo de massa de forragem (26.764 kg ha-1 de MS) quanto o acúmulo diário de massa de forragem (82 kg ha-1 por dia de MS). A utiliza o da associa o entre Arachis pintoi + 200 kg ha-1 de N e Coastcross + 200 kg ha-1 de N, possibilitou o melhor desempenho animal, com GMD de 0,570 e 0,500 kg e taxa de lota o de 3,51 e 3,26 UA ha-1, respectivamente. A utiliza o de pastagem consorciada sem a associa o com doses de nitrogênio (100 e 200 kg ha-1) n o favoreceu (p > 0,05) o acúmulo de massa de forrageme a taxa de acúmulo diária. A utiliza o de 200 kg ha-1 de N, com e sem a leguminosa, proporcionou o melhor desempenho e lota o animal por área. The objective of this study was to evaluate dry matter production and animal performance in pastures of Coastcross + Arachis pintoi; Coastcross + Arachis pintoi with 100 kg ha-1 of N; Coastcross +Arachis pintoi with 200 kg ha-1 of N and Coastcross with 200 kg ha-1 of N, during winter, spring, summer and autumn. The experimental design was complete randomized blocks with split-plot parcels, with two repetitions. The study evaluated the accumulation of foragemass and dairy accumulation of forage mass, average daily gain (ADG), live weight gain and stocking rate. The used of Coastcross + 200 kg ha-1 of N and the best climatic conditions in the spring and summer, favored the accumulation of forage mass (26,764 kg ha-1 of DM)and daily accumulation of forage mass (82 kg ha-1 day-1 of DM). The use of the association between Arachis pintoi + 200 kg ha-1 of N and Coastcross + 200 kg ha-1 of N, produces best animal performance, with ADG of 0.570 and 0.500 kg and stocking rate of 3,51 and 3.26AU ha-1, respectively. The use of pasture intercropping without association with doses of nitrogen (100 and 200 kg ha-1) did not favor (p > 0.05) the accumulation of forage mass and dairy accumulation of forage mass. The utlization of 200 kg ha
