Abstract: Vários estudos têm sido realizados buscando um tratamento eficaz que n o só auxilie na recupera o da árealesada pela queimadura, como na preven o da sepse. Esta pesquisa visa identificar os medicamentos maiseficazes no tratamento para queimaduras padronizadas de segundo grau por contato na regi o dorsal de ratos,cujo tegumento assemelha-se ao humano. Os animais foram distribuídos em 4 grupos, onde um n o sofreunenhum tipo de tratamento (grupo controle). Nos demais, os ratos foram distribuídos aleatoriamente emgrupos para testar 3 agentes tópicos, sendo utilizados para este experimento: sulfadiazina de prata (SP), ácidohialur nico (AH) e ácido ascórbico (AA). Após a queimadura, realizaram-se aplica es dos trêsmedicamentos sobre as feridas durante períodos de 5, 10 e 15 dias. Após o sacrifício dos animais ao final dos3 períodos de tratamento, foram retiradas amostras do tegumento das regi es lesadas para análisehistopatológica, mediante de técnicas de rotina. Observou-se que o AH apresentou maior poder decicatriza o nos 5 primeiros dias de pesquisa (p= 0,032). Ao término dos 15 dias, concluiu-se que todas asles es sofreram reepiteliza o, inclusive as que n o receberam qualquer tipo de tratamento, do grupocontrole. Embora o profissional de enfermagem deva seguir a terapêutica estabelecida pelas institui es desaúde, ele deve aplicar seus conhecimentos técnicos e científicos para propor eventuais mudan as, visando àpromo o e recupera o de saúde, conforme disponibilidade de cada institui o, limitando assim o tempo deestadia nos hospitais.

Abstract: The angiotensin receptors type 1 (AT1) have affinity by Losartan®, low affinity to non-peptides antagonists and similar effect as Angiotensin-convert-enzyme inhibitors. It have been reported that natural and synthetic products might reduce the genotoxic and cytotoxic effects related to stannous chloride (SnCl2). SnCl2 is used in nuclear medicine as a reducing agent to obtain technetium-99 m-radiopharmaceuticals. The aim of this work was to evaluate the cellular effects produced by a solution of Losartan® (25 mg/ml) on the survival of Escherichia coli AB1157 in the presence and absence of SnCl2, and on the osmotic fragility of erythrocytes of the blood of Wistar rats. Briefly, blood sample was withdrawn by Wistar rats with heparinized syringe and incubated with Losartan® solution. Saline (NaCL 0.9%) was used as a control. The samples were gently mixed with hypotonic solutions of NaCl. After that it was centrifuged and the supernadant isolated for optical determination of the hemoglobin present. E. coli AB1157 cultures (exponential growth phase) were collected by centrifugation, washed and resuspended in 0.9%NaCl. Samples were incubated in water bath shaker with: (a) SnCl2 (25 μg/ml), (b) Losartan® (25 mg/ml) and (c) SnCl2 (25 μg/ml) + Losartan® (25 mg/ml). Incubation with 0.9% NaCl was also carried out (control). At 60 min intervals, aliquots were withdrawn, diluted, spread onto Petri dishes with solid LB medium and incubated overnight. The colonies formed were counted and the survival fractions calculated. Statistical analysis was performed. The results showed that there was a significantly increase (P < 0.05) in the osmotic fragility of the blood cells treated with Losartan®. Moreover, Losartan® was also able to protect the E. coli cultures against the lesive action of SnCl2. Although, in erythrocyte the osmotic fragility was increased by the presence of Losartan® that could 1) alter the physical properties of this cell, or 2) had a direct or indirect effect on the intracellular sodium concentration or 3) had acted on the cardiovascular system. It suggested that the Losartan® did interfere strongly with cellular metabolism and did alter the survival fractions of E. coli AB1157.

Abstract: aiming to determine the relationship between the frequency of testicular shape and the andrological aspects in young nellore bulls, 18,676 animals were assessed. all andrological examinations were performed between the years 2000 and 2008. animals were classified as able for breeding, able for breeding in natural mating system, unable for breeding and discarded. the testicular shape was classified as long, fairly long, oval-long, spherical-oval, and spherical. the analysis of pearson correlations was performed for testicular shape with scrotal circumference, testicular volume, progressive motility, sperm vigor, major defects, minor defects and total defects. testicles with oval shape prevailed (99.61%). it was obseved that 76.34; 66.34; 64.34; 58.33 and 50.00% of the animals were classified as sound for breeding for shapes long, fairly long, oval-long, spherical-oval, and spherical, respectively. correlations between testicular shape with scrotal circumference, testicular volume, progressive motility, sperm vigor, major, minor and total defects were 0.26; 0.08; 0.00; 0.11; -0.02; 0.02 and -0.01, respectively. testicular shape had no influence upon the andrological examination results. testicles of long shape were prevalent within the population.

Abstract: background - anal cancer is an uncommon malignancy accounting for only a small (4%) percentage of intestinal cancer. the authors described the clinical aspects and the treatment of the patients with squamous cell carcinoma of the canal anal. patients - eleven patients with squamous cell carcinoma treated among 1995 and 1999, were analyzed retrospectively. nine were women and two were men. the mean age was 57.6 years old (range 35-82 years old). results - the most common symptoms were rectal bleeding, local tumor and pain. six of them had previous anal benign disease and two had metastases at the diagnosis. all were submitted to systemic chemotherapy with 5-fluorouracil and mitomicin and radiotherapy with 4500cgy. four patients had residual disease after chemo radiation and salvage surgery with abdominoperineal resection was done. three patients had recurrence and four died from the disease. conclusion - most of our patients were women. the chemo radiation can be a curable treatment in patients with local disease; conversely in patients with residual disease, abdominoperineal resection must be done. although anal cancer is an often curable disease, four patients died because the diagnosis was done in advanced stage.

Abstract: in the course of studies on the effects of septal area lesions on neuroimmunomodulation and walker 256 tumor development, it was observed that tumor-induced sodium and water retention was less marked in lesioned than in non-lesioned rats. in the present study possible mechanisms involved in this phenomenon were investigated. the experiments were performed in septal-lesioned (lw; n = 15) and sham-operated (sw; n = 7) 8-week-old male wistar rats, which received multifocal simultaneous subcutaneous (sc) inoculations of walker 256 tumor cells about 30 days after the stereotaxic surgery. control groups (no tumor, sham-operated food-restricted (sfr), n = 7) and lesioned food-restricted (lfr, n = 10) were subjected to a feeding pattern similar to that observed in tumor-bearing animals. multifocal inoculation of walker 256 tumor rapidly induces anorexia, which is paradoxically accompanied by an increase in body weight, as a result of renal na+ and fluid retention. these effects of the tumor were also seen in lw rats, although the rise in fractional sodium balance during the early clinical period was significantly smaller than in sw rats (day 4: sw = 47.6 ± 6.4% and lw = 13.8 ± 5.2%; day 5: sw = 57.5 ± 3.5% and lw = 25.7 ± 4.8%; day 6: sw = 54.4 ± 3.8% and lw = 32.1 ± 4.4%; p<0.05), suggesting a temporary reduction in tumor-induced sodium retention. in contrast, urine output was significantly reduced in sw rats and increased in lw rats (lw up to -0.85 and sw up to 4.5 ml/100 g body weight), with no change in osmolar excretion. these temporary changes in the tumor's effects on lw rats may reflect a "reversal" of the secondary central antidiuretic response induced by the tumor (from antidiuretic to diuretic).

Abstract: the infant mortality rate is one of the key indicators used to measure a population's quality of life. the state of rio grande do sul has a social and economic indicator called the socioeconomic development index (idese). most studies analyze the infant mortality rate in relation to risk factors, visually aided by maps. this study presents the methodology and an application of a spatial epidemiology method called the ecological correlation, using hierarchical bayesian procedures. the article discusses the main problems found in ecological correlations, such as spatial autocorrelation and the estimator's instability for small areas. to overcome these difficulties, the relative risk estimate obtained by spatial regression analysis using fully bayesian estimation is presented. the infant mortality rate is analyzed in all 496 municipalities of rio grande do sul for the years 2001 to 2004. several models with spatial component and different variables from the idese/2003 were compared. the model using spatial structure along with the variable "education" was considered the best choice. with this methodology, it was possible to obtain a more interpretable pattern of infant mortality risk in rio grande do sul.
