ABSTRACT
ABSTRACT Background: The health benefits associated with moderate wine consumption, as with ethanol and phenolic compounds, include different mechanisms still little understandable. Aim: Evaluate glycemic and weight variations, and the deposit of triglycerides, cholesterol and liver glycogen with red wine consumption. Methods: 60 ApoE knockout mice were divided into three groups of 20: Wine Group (WG), Ethanol Group (EG) and Water Group (WAG). They received daily: WG 50 ml of wine and 50 ml water; EG 6 ml ethanol and WAG 94 ml of water. All groups were followed for four months. The food intake was monitored daily, in the period from eight to ten hours and held every five days. The measurement of water intake was also made every five days. The weighing of the animals took place every ten days. Results: The WG had higher weight increase as compared to the other groups. The concentration of hepatic triglyceride was higher in WG (57%) and the EG group was lower (31.6%, p<0.01) than the control. The concentration of cholesterol was lower in the WG (23.6%), as well as EG (24.5%, p<0.05). The concentration of glycogen was higher in WG (16%) and fasting blood glucose was higher in EG compared to the other groups but not both demonstrated a statistically significant difference. Conclusion: The WG increased triglyceride and WAG decreased cholesterol. The triglyceride may be increased due to the high caloric value of wine or some unknown property that led to significant increase in subcutaneous andretroperitoneal fat in mice.
RESUMO Racional: Os benefícios para a saúde associados ao consumo moderado de vinho, como etanol e compostos fenólicos, incluem mecanismos diferentes ainda pouco compreensíveis. Objetivo: Avaliar as variações da glicemia, peso e depósito de triglicrideos, colesterol e glicogênio hepático com o uso de vinho tinto. Métodos: Sessenta camundongos ApoE knockout foram divididos em três grupos de 20: Grupo do Vinho (WG), grupo do Etanol (EG) Grupo Água (WAG). Cada grupo recebeu diariamente: WG 50 ml de vinho e 50 ml de água; EG 6 ml de etanol e WAG 94 ml de água. Resultados: O WG teve aumento de peso mais elevado em comparação com os outros grupos. A concentração de triglicerídeos foi maior no WG (57%) e no grupo EG inferior (31,6%) do que no controle (p <0,01). A concentração de colesterol foi inferior no WG (23,6%) e no EG (24,5%, p<0,05). A concentração de glicogênio foi maior no WG (16%); a glicemia capilar foi maior no EG em comparação com os outros grupos, mas não demonstrou diferença estatisticamente significativa. Conclusão: Triglicerídeos ficaram aumentados no WG e o colesterol diminuiu no WAG. Os triglicerídeos podem ter aumentado devido ao alto valor calórico do vinho ou alguma propriedade desconhecida que levou ao aumento significativo da gordura subcutânea e retroperitoneal nos camundongos.

PURPOSE: To evaluate macro and microscopically, changes following the use of the aqueous extract of babassu (Orbignya phalerata) in the lung parenchyma and pleura of rats. METHODS: Sixty adult male rats with average weight of 350 g, were randomized into two groups of 30 animals (experimental and control) further divided into sub-groups of 10 to be sacrificed at 48 h, 72 h and 21 days. The substance was injected into the right pleura of the animals. RESULTS: There was intense pleuropulmonary macroscopic reaction with statistically significant differences between groups respectively (p<0.05, p<0.02, p<0.03). Microscopically, no statistically significant difference was evident (p>0.05). CONCLUSION: The aqueous extract of babassu (Orbignya phalerata) was found to be highly irritating to the pleura and lung of rats, evidenced macroscopically by numerous adhesions and inflammation while no major changes were evident microscopically.

Summary Introduction: solitary fibrous tumor of the pleura (SFTP) is a rare tumor arising from mesenchymatous cells in submesothelial pleural tissue which, unlike mesothelioma, is not related to asbestos or smoking. Methods: report of four patients who underwent surgical treatment for giant SFTP and review of the pertinent literature. Results: of the four patients operated, two presented symptoms including cough, chest pain and feeling of compression, whereas the other two subjects were asymptomatic. All patients underwent complete surgical resection by wide posterolateral thoracotomy, and surgical specimens removed with minimum bleeding. None of the cases required complementary lobectomy or segmentectomy. All tumors were histologically benign. Conclusion: complete resection of the lesion is the treatment of choice in all SFTP cases. Prognosis of the benign lesion is excellent, although close follow-up is necessary. In the rarer, more aggressive forms, treatment may be complemented by adjunctive chemotherapy or radiotherapy, the benefits of which have yet to be confirmed. .
Resumo Introdução: o tumor fibroso solitário de pleura (TFSP) é um tumor raro com origem nas células mesenquimatosas do tecido pleural submesotelial, que, ao contrário do mesotelioma, não tem relação com asbesto ou tabagismo. Método: relato de caso de quatro pacientes submetidos a tratamento cirúrgico para TFSP gigante e revisão da literatura pertinente. Resultados: dos quatro pacientes operados, dois apresentaram sintomas como tosse, dores no peito e sensação de compressão enquanto os demais foram assintomáticos. Todos os pacientes foram submetidos à ressecção cirúrgica total por toracotomia posterolateral ampla, sendo os espécimes cirúrgicos removidos com mínimo sangramento. Em nenhum dos casos houve necessidade de lobectomia ou segmentectomia complementar. Todos os tumores eram histologicamente benignos. Conclusão: a ressecção total da lesão constitui o tratamento de escolha em todos os casos de TFSP. O prognóstico de lesões benignas é excelente embora o acompanhamento seja necessário. Nas formas mais raras e agressivas, o tratamento pode incluir quimioterapia ou radioterapia adjunta, cujos benefícios ainda não foram confirmados. .

OBJETIVO: Avaliar a espirometria no pré e pós-operatório de doentes com sequela de tuberculose, submetidos à lobectomia. MÉTODOS: Foram selecionados 20 doentes, com idade entre 15 e 56 anos, de ambos os sexos, com história pregressa de tratamento de tuberculose, apresentando infecção de repetição ou hemoptises. Foram submetidos à lobectomia pulmonar. O tempo de tratamento da tuberculose foi seis meses e o aparecimento dos sintomas entre um e 32 anos. Foram avaliadas a capacidade vital (CV), a capacidade vital forçada (CVF), o volume expiratório forçado (VEF1), o VEF1/CVF, o fluxo expiratório forçado (FEF) e o pico de fluxo expiratório (PFE) após o primeiro, terceiro e sexto meses em relação ao pré-operatório. O nível de significância (á) aplicado em todos os testes foi 5%, ou seja, considerou-se significativo quando p<0,05. RESULTADOS: As Médias encontradas foram as seguintes: Capacidade Vital (CV) Pré-operatória-2,83 ; 1º PO 2,12; 3º PO 2,31; 6º PO 2,43. Capacidade Vital Forçada (CVF) Pré-operatória- 2,97; 1º PO 2,21; 3º PO 2,35; 6º PO 2,53. Volume Expiratório no 1º Segundo (VEF1) Pré-operatório 2,23; 1º PO 1,75; 3º PO 1,81; 6º PO 1,97. Houve diminuição acentuada das funções respiratórias no primeiro mês de pós-operatório, porém houve melhora dos parâmetros a partir do terceiro mês, com progressivo aumento até o sexto mês de pós-operatório. CONCLUSÃO: Não houve recuperação dos parâmetros espirométricos, comparados aos do pré operatório, após seis meses de pós-operatório nos pacientes com sequela de tuberculose submetidos à lobectomia.
OBJECTIVE: To evaluate pre and post-operative spirometry in patients with tuberculosis sequelae undergoing lobectomy. METHODS: We selected 20 patients, aged between 15 and 56 years, of both genders, with a history of tuberculosis treatment, with repeated infections or hemoptysis and indication of pulmonary lobectomy. The tuberculosis treatment time was six months, and onset of symptoms, between one and 32. We evaluated and compared vital capacity (VC), forced vital capacity (FVC), forced expiratory volume (FEV1), the FEV1/FVC, forced expiratory flow (FEF) and peak expiratory flow (PEF) preoperatively and after the first, third and sixth postoperative months (POM). The significance level (á) used in all tests was 5%, ie, it was considered significant when p <0.05. RESULTS: The averages found were: Vital Capacity (VC) - Preoperative: 2.83; 1st POM: 2.12; 3rd POM: 2.31; 6th POM: 2.43. Forced Vital Capacity (FVC) - Preoperative: 2.97; 1st POM: 2.21; 3rd POM: 2.35; 6th POM: 2.53. Expiratory Volume in 1 second (FEV1) - Preoperative: 2.23; 1st POM: 1.75; 3rd POM: 1.81; 6th POM 1.97. There was marked decrease in lung function in the first month after surgery, but there was an improvement of the parameters from the third month, with gradual increase up to the sixth month. CONCLUSION: There was no recovery of preoperative spirometric parameters at six months postoperatively in patients with sequelae of tuberculosis submitted to lobectomy.

INTRODUÇÃO: O mesocarpo de Orbignya phalerata tem sido usado em estudos experimentais procurando verificar sua ação pró-inflamatória. OBJETIVO: Analisar comparativamente as alterações histológicas proporcionadas pelo extrato aquoso do babaçu nas feridas cutâneas. MÉTODOS: Sessenta ratos da linhagem Wistar, adultos, machos, foram utilizados. O procedimento experimental constituiu-se em uma incisão circular de 2cm de diâmetro na pele com punch metálico. Após este procedimento comum a todos, os animais foram distribuídos aleatoriamente em dois grupos contendo 30 animais cada. No grupo controle não foi utilizada a substância pesquisada e sim, solução fisiológica (Cloreto de sódio a 0,9 por cento). No grupo experimento utilizou-se solução aquosa de Orbignya phalerata em uso tópico. Os animais foram acompanhados e mortos em sete, 14 e 21 dias. Foi feita análise histológica comparativa entre os grupos. RESULTADOS: Observou-se diferença significativa a favor da cicatrização do grupo experimento em relação ao grupo controle nos 7° e 14° dias, no que diz respeito à reepitelização. CONCLUSÃO: O uso tópico do mesocarpo de Orbignya phalerata (Babassu) contribuiu positivamente para a cicatrização das feridas cutâneas em ratos com a dosagem de 25mg/ml.
INTRODUCTION: The mesocarp of Babassu (Orbignya phalerata) has been used in experimental studies trying to check its pro-inflammatory effect. PURPOSE: To analyse comparatively the histological changes made by the water extract of Babassu in skin surgical wounds. METHODS: Sixty Wistar adults male rats were used. The experimental procedure was a circle skin incision of 2 cm in diameter made with a metal punch. After this procedure done in all animals, they were randomized in two groups of 30. In the control group, the phytotherapic agent wasn't used but saline solutin. In the experimental group, the water extract of Orbignya phalerata was used in the cut sites. All animals were followed and killed after seven, 14 and 21 days. Comparative histological analysis was made among the groups. RESULTS: In the microscopic view, a significant reepitelization effect on the healing process of the experimental group in relation to the control group in the 7th and 14th days, was recognized. CONCLUSION: The use of the mesocarp of Orbignya phalerata in skin surgical wounds contributed positively in the healing process in rats.

ABSTRACT
The Morgagni hernia is the rarest kind of diaphragmatic hernia , occurring in 3 percent of all cases. It consists of the protrusion of the abdominal content into the thoracic cavity including omentum and transverse colon, among others. It is more common in the right side and appears more frequently after 40 years of age or after a raise in the intra-abdominal pressure. Patients with Morgagni hernia are usually asymptomatic. In the X-ray it appears like an opaque image in the cardiophrenic angle.Surgical correction is the treatment of choice for this conditions. We present one case of Morgagni hernia successfully treated.
