Abstract: The aim was to detect the presence of bundles of collagen fibers in the margins of the esophageal hiatus and establish if there is any relationship of these bundles with the anatomy of the hiatus. Ten adult male cadavers, with no gross anatomical alteration caused by trauma, surgery or disease, upon the esophageal hiatus were used in the study. A piece of anatomical structure comprising the diaphragm with the esophageal hiatus and adjacent tissues was removed, dissected and 10% formol embedding. With the aid of a digital caliper, measurements of the perimeter of the esophageal hiatus were done both in the abdominal and thoracic sides. For the structural study each margin was divided in six sections. Staining techniques of Masson and Picrosirius-hematoxilin were used. Collagen fibers bundles had been found in 8/10 studied cadavers, distributed in 13 margins of the hiatus, of which 7 to left and 6 to the right. The muscle fibers originating from the right pillar had participated in forming both margins of the esophageal hiatus in 60% of cadavers, while in 40%, the fibers of the left pillar had formed the medial side of the right margin. The right margin was statistically thicker than the left. It did not have a correlation between the measures of the vertices of the angles superior/inferior and the transversal measure of the esophageal hiatus. The measures between the vertices of the angles superior/inferior, respectively, with the central tendon and median arcuate ligament, had presented thoracic values that tended to the double, in relation to the abdominal ones, and had been statistically significant. These distances were smaller in cadavers who possessed bundles of collagen fibers in the margins of the esophageal hiatus. Bundles of collagen fibers bundles were found in 65% of the 20 margins of the esophageal hiatus. The margins of the esophageal hiatus were predominantly formed by muscles fibers originated of the right pillar of the muscle diaphragm. The anatomical and morphometric data presented statistically significant values regarding: thickness of the right arm in relation to the left; distance between the vertex of the superior angle and the central tendon; and distance between the vertex of the inferior angle and the median arcuate ligament.

Abstract: PURPOSE: The objective of the experimental study is to detect the macroscopic and microscopic alterations of the mesenterium and parietal peritoneum when hypertonic glucose aqueous solution 10%-25% is administrated into the peritoneal cavity of the rat. METHODS: 90 Wistar females young rats adults were used weighin between 180-250 g, numbered 1 to 90, establishing unique group and divided in three groups (A, B, C) of 30 animals chosen aleatory manner. 0,9% saline solution was used called control group, or group A, 10% glucose solution named group B, and in the others 30 was used 25% glucose solution named group C, differing in the observation period, (06h, 24h and 48h), but with the same procedure. A midline abdominal wall laparotomy was made and in the animals of the control group was injected 2 ml of a 0,9% saline solution into the peritoneal cavity. After, we made a suture in mass without to include the peritoneum. For the others groups (B, C) the rats received 10% glucose solution and 25% glucose solution injected into the peritoneal cavity respectively. All groups were kept under observation and the results were submitted to statistical analysis by a longitudinal and transversal comparative study. RESULTS: A new surgery was done in 6h, 24h and 48h, and we observed in macroscopic evaluation, the presence of fluid, serous uniforme and rosy all over the cavity. Vascular congestion was present. We dried out 90 fragments of mesenterium and 90 fragments of parietal peritonium bilateral. In the microscopic study, necrosis was not present. For the mesenterium histological study we observed 16 cases (17,8%) unspecific chronic inflammation, 30 cases (33,4%) hiperplasic linfonod, 10 cases (11,1%) high vascular congestion, 6 cases (6,6%) reaction fibrosis and 28 cases (31,1%) no alteration. For the parietal peritonium histological study we observed 6 cases (3,3%) reaction fibrosis and 174 cases (96,7%) no alteration. Giant cell was not present. In the statistical analisys statistic there is no significance between the groups (p>0,05). CONCLUSION: Hypertonic glucose solution and NaCl 0,9% on the mesenterium and parietal peritonium do not produce tissue necrosis in a rat and the inflammation process has the same intensity.

Abstract: El conocimiento de la vascularización de la pared anterior del abdomen es un importante instrumento para la realización de incisiones y punciones abdominales, contribuyendo a evitar algunas complicaciones reurrentes de este procedimiento. Con el propósito de estudiar la emergencia y el trayecto de las arterias epigástricas superiores, fueron disecados 32 cadáveres adultos, del sexo masculino, no fijados, blancos y no blancos, con edades entre 18 y 65 a os. Se observó el trayecto de las arterias epigástricas superiores, su emergencia y su forma de distribución. Las arterias epigástricas superiores emergieron por atrás del 7 cartílago costal en todos los casos. En el 75% de los casos las arterias epigástricas se presentaron como un tronco único y en 15 casos (23,44%) bifurcadas, siendo 11 a la derecha y 4 a la izquierda y en 1 caso (1,56%) a la izquierda. En este último, caso dio origen a tres ramos principales. Cuando era un tronco único, su trayecto fue descendente de medial para lateral en relación al margen lateral del músculo recto del abdomen. Cuando era bifurcada, sus ramos se separaron uno del otro luego de su emergencia, volviendo a convergir próximo a la cicatriz umbilical The knowledge of the vascularization of the anterior abdominal wall is very important on the incisions and abdominal punctures, contributing to avoid the injuries of this vessels during this procedures. With the goal to study the emergency and the trajectory of the superior epigastric arteries, 32 adult not preserved cadavers, of the masculine sex, white and not white, with age between 18 and 65 years were studied. The trajectory of the superior epigastric arteries, your emergency and distribution form were observed. The superior epigástric arteries emerged behind to 7th costal cartilage in all the cases. In 75% of the cases they appeared like an only trunk and in 15 cases (23,44%) they appeared forked, being 11 to the right and 04 to the left and in 01 case (1,56%) to the left, it'd origin three main branches. When in an only trunk, your trajectory went descending of medial for lateral in relationship to the lateral margin of the rectus abdominal muscle. When forked, your branches separated one of the other immediatelly after your emergency, back converging close to the umbilical scar

International Journal of Molecular Sciences , 2009, DOI: 10.3390/ijms10115090
Abstract: Natural mycoflora and co-occurrence of fumonisins (FB1, FB2) and aflatoxins (AFB1, AFB2, AFG1 and AFG2) in freshly harvested corn grain samples from four regions of Brazil were investigated. Fusarium verticillioides was predominant in all samples. Analysis of fumonisins showed that 98% of the samples were contaminated with FB1 and 74.5% with FB1 + FB2, with toxin levels ranging from 0.015 to 9.67 μg/g for FB1 and from 0.015 to 3.16 μg/g for FB2. Twenty-one (10.5%) samples were contaminated with AFB1, seven (3.5%) with AFB2 and only one (0.5%) with AFG1 and AFG2. Co-contamination with aflatoxins and fumonisins was observed in 7% of the samples. The highest contamination of fumonisins and aflatoxins was observed in Nova Odessa (SP) and Várzea Grande (MT), respectively. The lowest contamination of these mycotoxins was found in Várzea Grande and Nova Odessa, respectively.

Abstract: the effects of prolonged oral exposure (28 days) to fumonisin were studied in young pigs. animals were divided into three experimental groups and fed ad libitum using ratio containing: a) 0mg of fb1.kg-1 (as control); b) 10mg of fb1.kg-1; c) 30mg of fb1.kg-1. pigs were observed twice a day; their weights and feed intake were registered weekly. between the 20th and 24th day of intoxication, pigs in group c presented a decrease in feed intake and weight gain, and showed characteristic signs of porcine pulmonary edema, which was the death cause of one of the animals in this group on the 23rd day of the trial. after 28 days, animals were necropsized, their organs were submitted to macroscopic and histopathological analyses, and to the study of intestinal morphology and histology. among the pigs that showed clinic signs of intoxication, pulmonary and hepatic lesions were observed. in intestine segments, a decrease on the height of the villus and the depth of the crypts as well as an increase on gland proportion per epithelial tissue were observed. it was concluded that substantial productivity losses may be induced on pigs fed ration contaminated with low levels of fumonisins.

Abstract: the extraction of sand in the valley of the paraíba do sul river, carried out in a vulnerable environment, is responsible for significant environmental impacts. this work had the objective of investigating the increase of the total area of lakes created in the mining process for a period of 11 years and of verifying the influence of the evaporation from these lakes on the regional water balance. thus, a geographic information system data basis was implemented using the gis software package, spring, and landsat imagery. scenes 218/76 and 219/76 were used for the quantification of the mining areas and for the assessment of the evolution of the activity in the area for a period of 11 years. with data from a local climatological station (unitau/inmet-83784) integrated into the database and with the total area of artificial lakes resultant from sand mining activity, it was possible to estimate the increase of the evaporation rate due to this activity. an increase of 591 ha, in 1993 to 1,726 ha in 2003 in the area of lakes was observed. the resulting increase in the evaporating rate was 203% with 19,157,022 m3 evaporated in 2003 correspondent to the consumption of a city with more than 326,000 inhabitants, considering the average consumption for the state of s?o paulo which is greater than the brazilian average.
