Abstract: objectives: the acute peritonitis is an important cause of sepsis and death on intensive care units and surgery. the treatment must include: systemical use of antibiotics, drainage of abscess and restauration of gastrointestinal integrity. the topical use of antibiotics in the peritoneal cavity is controversial. the aim of this study was to evaluate the use of topical use of ampicilin/sulbactam in the treatment of peritonitis. methods: we measured the plasmatic levels of nitric oxide, count of eosinophils, lymphocytes, monocytes, and neutrophils in blood and peritoneal cavity, using a model of peritonitis in rats (transfixation and ligature of cecum). twenty four wistar rats were divided in 4 groups (n=6 each). group a: induction of peritonitis with ligature of cecum and topical treatment with saline; group b: induction of peritonitis with ligature of cecum and topical treatment with ampicilin/sulbactam; group c: transfixation of cecum; group d: laparotomy and peritoneal exsudate + blood sample. the transfixation-ligture of cecum remained for 24 hs before treatment. a relaparotomy was performed in 18 rats and peritoneal exsudate/blood were collected. dosage of nitric oxide, count of eosinophil, lynphocytes, monocytes, and neutrophils in blood and peritoneal exsudte were done. results: the difference was not significant in the levels of nitric oxide, eosinophil, lynphocytes, monocytes, and neutrophils in blood and peritoneal exsudate (p > 0,05) among the studied groups. concluson: the use of ampicilin associated to sulbactam via intraperitoneal in rats with fecal peritonitis did not change survival.; the levels of plama nitric oxide, count of eosinophil, lynphocytes, monocytes, and neutrophils in blood and peritoneal exsudate were not affected.

Abstract: the freshwater snail gundlachia ticaga (marcus & marcus, 1962) is widely distributed in brazil, but its morphology has been poorly studied. we compared the shell morphology of samples from four sites (vila do abra?o, vila de provetá, parnaioca and praia do sul) in ilha grande (angra dos reis, state of rio de janeiro) in order to evaluate differences within and among four populations. we used nine morphometric characters representing shell size and shape. to analyze shell morphology we considered aperture shape, sculpture of teleoconch, apex carving and position. the resulting dataset was correlated by pearson′s linear correlation and shell differences among populations were tested using anova and discriminant function analysis. the results showed that there is significant variation among populations concerning shell shape and morphology. shells from preserved localities (praia do sul and parnaioca) and shells from highly modified environments (vila do abra?o and vila de provetá) were the most similar to each other. results from the visual assessment and from the discriminant analysis were almost identical. the shell indices are the most important variables in the differentiation of samples. the observed variation corroborates the hypothesis that g. ticaga displays phenotypic plasticity, which may lead to wrong identifications. narrower shells with an elongate aperture could be misidentified as ferrissia walker, 1903 and, broader shells with a roundish aperture could be wrongly identified as burnupia walker, 1912. we confirmed that the absence of radial lines is not a good diagnostic character for g. ticaga. the analysis of the apical micro-sculpture and soft parts is essential for a correct identification.

Abstract: We conducted a cross-sectional study with 395 bank workers in Recife, Northeast Brazil. Symptoms of upper limbs and 'RSI-like condition' were assessed by a simple questionnaire, which was used to screen probable cases of RSI. The diagnosis of RSI was confirmed by clinical examination. The associations of potential risk factors and the outcomes were assessed by multiple logistic regression analysis.We found prevalence rates of 56% for symptoms of the upper limbs and 30% for 'RSI-like condition'. The estimated prevalence of clinically confirmed cases of RSI was 22%. Female sex and occupation (as cashier or clerk) increased the risk of all conditions, but the associations were stronger for cases of RSI than for less specific diagnoses of 'RSI-like condition' and symptoms of upper limbs. Age was inversely related to the risk of symptoms of upper limbs but not to 'RSI-like' or RSI.The variation in the magnitude of risk according to the outcome assessed suggests that previous studies using different definitions may not be immediately comparable. We propose the use of a simple instrument to screen cases of RSI in population based studies, which still needs to be validated in other populations. The high prevalence of RSI and related conditions in this population suggests the need for urgent interventions to tackle the problem, which could be directed to individuals at higher risk and to changes in the work organization and environment of the general population.Repetitive strain injury (RSI) is an occupational disease that considerably impacts workers' lives and has significant socio-economic repercussions. The burden of RSI to people affected and the society are undeniably large. One third of workers' compensation costs in the US private industry are due to RSI[1], and the direct costs with compensation exceeds US$ 20 billion in the Washington State alone[2]. In the Netherlands, 8% of the whole working population take time off work because of RSI symptoms [3]. The Health &

Abstract: human t cell lymphotropic virus type-1 (htlv-1) induces lymphocyte activation and proliferation, but little is known about the innate immune response due to htlv-1 infection. we evaluated the percentage of neutrophils that metabolize nitroblue tetrazolium (nbt) to formazan in htlv-1 infected subjects and the association between neutrophil activation and ifn-g and tnf-a levels. blood was collected from 35 htlv-1 carriers, from 8 patients with ham/tsp (htlv-1- associated myelopathy); 22 healthy individuals were evaluated for spontaneous and lipopolysaccharide (lps)-stimulated neutrophil activity (reduction of nbt to formazan). the production of ifn-g and tnf-a by unstimulated mononuclear cells was determined by elisa. spontaneous nbt levels, as well as spontaneous ifn-g and tnf-a production, were significantly higher (p<0.001) in htlv-1 infected subjects than in healthy individuals. a trend towards a positive correlation was noted, with increasing percentage of nbt positive neutrophils and levels of ifn-g. the high ifn-g producing htlv-1 patient group had significantly greater nbt than healthy controls, 43±24% and 17±4.8% respectively (p< 0.001), while no significant difference was observed between healthy controls and the low ifn-g-producing htlv-1 patient group (30±20%). spontaneous neutrophil activation is another marker of immune perturbation resulting from htlv-1 infection. in vivo activation of neutrophils observed in htlv-1 infected subjects is likely to be the same process that causes spontaneous ifn-g production, or it may partially result from direct ifn-g stimulation.

Abstract: Salvia hispanica L. is a herbacia plant that originates from Mexico and Guatemala, and it is currently known by the popular name of chia. Currently, chia seeds have been considered to be of great importance for human health and nutrition because they have a high concentration of polyunsaturated fatty acids. They contain the largest known percentage of fatty α-linolenic acid (ALA) in plants—approximately 68%. Furthermore, they are an excellent source of protein, dietary fiber, calcium, magnesium, iron, vitamin B and phenolic compounds that have antioxidant properties. However, despite the high nutritional value present in the food and the possible health benefits of its nutrients, there is a need to evaluate the bioaccessibility of its micronutrients to measure their effectiveness. Thus, we evaluated the chemical composition of chia seeds from different producers, their lipid profiles and the bioaccessibility of some of their minerals.
