PURPOSE: To evaluate the effects of aroeira (Schinus terebinthifolius) ointment on skin wound healing in rats. METHODS: Adult male rats (n=20) were divided into four groups of five animals each, as follows: G4, G7, G14 and G21, which corresponds to 4th, 7th, 14th and 21th days postoperatively. Each animal were made two incisions on the skin, including the subcutaneous tissue, in the right and left sides of thoracic region, separated by a distance of two inches. The right lesion was treated with base ointment (vaseline, lanolin); the left one was treated with base ointment containing 5% of aroeira oil. At the end of each experimental period the lesions were evaluated for the contraction degree. Then held the collection of fragments that were fixed in 10% formalin and processed for paraffin embedding. In the histological sections (5μm) was evaluated the morphology and quantified the collagen and blood vessels. The data obtained were submitted to ANOVA test complemented by Tukey-Kramer test (p<0.05). RESULTS: The contraction of the lesions was higher in wounds treated with aroeira oil than in controls at 7th and 14th days (p<0.01), whereas in the 21st day all lesions were already completely healed. The morphology showed granulation tissue more developed, with fibroblasts more bulky and collagen fibers more arranged in the experimental group at 4th, 7th and 14th days. The morphometry showed a significant increase in the quantification of collagen fibers in the experimental group at 7th and 14th days (p<0.05). CONCLUSION: The aroeira oil accelerates the healing process of wounds as a macroscopic, morphological and morphometrical analysis.

OBJETIVO: caracterizar a população em uso de via alternativa de alimentação internada em um hospital geral de referência. MÉTODO: estudo transversal prospectivo, tendo-se realizado coleta de dados em 229 prontuários de pacientes em uso de via alternativa de alimentação internados em enfermarias adultas de um hospital geral, identificando-se dados referentes à via alternativa de alimentação em uso, justificativas clínicas, doença(s) de base e demais aspectos clínicos relacionados aos distúrbios de deglutição. RESULTADOS: houve predomínio do sexo masculino (55,02%); 70,3% dos pacientes apresentaram diagnóstico de alguma doença neurológica e a via de alimentação mais utilizada foi a sonda nasoenteral (82,53%). Embora a pneumonia e a desnutrição tenham sido diagnosticadas na minoria dos casos (35,08% e 10,04%), houve associação entre as variáveis pneumonia e disfagia (p=0,0098), não ocorrendo o mesmo entre desnutrição e disfagia (p=0,0759). A disfagia foi citada em apenas em 6,55% dos casos. Observou-se, ainda, alta frequência de ausência de dados referente aos sinais e sintomas de dificuldade de alimentação e de justificativas para indicação da via alternativa de alimentação prescrita. CONCLUSÃO: embora a população estudada tenha apresentado fatores de risco para desenvolvimento de distúrbios da deglutição, como doenças de base com alta ocorrência de disfagia e alteração do nível de consciência e/ou sonolência, a baixa frequência do diagnóstico da disfagia e a constante falta de dados relacionados ao contexto alimentar revelaram a pouca importância dada às manifestações funcionais pela unidade hospitalar estudada.

PURPOSE: to characterize the population submitted to administration of alternative feeding route admitted to a general hospital in the state of Alagoas. METHOD: data from medical records of 229 patients admitted to adult infirmary were investigated. Data referring to the administration of alternative feeding route in use and clinical aspects related to swallowing disorders were analyzed. RESULTS: there was a predominance of male participants (55.02%) in the sample. From the total sample, 70.3% of participants were diagnosed with a neurological disease and most of them used the nasogastric tube (82.53%) as feeding route. There was an association between the variables pneumonia and dysphagia (p = 0.0098). However, no association between malnutrition and dysphagia was found (p = 0.0759). There was also a high frequency of absence of data concerning symptoms of feeding difficulty as well as about justification for the use of the alternative feeding route. CONCLUSION: the population studied presented risk factors for development of dysphagia. The shortage of data revealed the little importance given to functional manifestation at the hospital context.

OBJETIVO: Avaliar os efeitos do extrato de angico (Anadenanthera colubrina var. cebil) na cicatrização em pele de ratos. MÉTODOS: Ratos machos adultos (n=20) foram distribuídos em quatro grupos de cinco animais cada, a saber: G4, G7, G14 e G21, o que corresponde a quatro, sete, 14 e 21 dias de pós-operatório. Cada grupo recebeu duas incisões na pele compreendendo o tecido subcutâneo, nos antímeros direito e esquerdo da região torácica, separadas por uma distância de dois cm. A lesão esquerda com extrato alcoólico de angico (5%), iniciando-se logo após a cirurgia por 21 dias consecutivos. Ao final de cada período (4, 7, 14 e 21 de pós-operatório) experimental foram coletados fragmentos da área da ferida, fixada em formol a 10% e processadas para inclusão em parafina. Nos cortes histológicos com 5 µm de espessura, foram realizados métodos imunoistoquímicos para detecção dos vasos sanguíneos (VEGF) e coloração pela hematoxilina para análise morfológica. Os dados obtidos foram submetidos à análise estatística ANOVA complementada pelo teste de Tukey-Kramer (p<0,05). RESULTADOS: A análise morfológica mostrou fibroblastos mais volumosos e alta concentração de fibras colágenas no 7º e 14º dias nas feridas tratadas com extrato de angico. A análise morfométrica demonstrou aumento significativo no número de vasos sanguíneos no sétimo e 14º dias (p<0,01) de pós-operatório em feridas tratadas com extrato de angico. CONCLUSÃO: O extrato hidroalcoólico a 5% da casca e entrecasca do angico (Anadenanthera colubrina var. cebil) acelera a neoangiogênese em feridas cutâneas de ratos.

PURPOSE: To study the effects of the angico extract (Anadenanthera colubrina var. cebil) on the healing of rat skin. METHODS: Twenty adult rats were divided into four groups of five animals each, the G4, G7, G14 and G21, which corresponds to the respective postoperative days. Each group received two incisions on skin and subcutaneous tissue in the right and left antimere of the thoracic region, separated by a distance of 2 cm. The right lesion was treated daily with saline and the left with the angico alcoholic extract (5%). At the end of each experimental period, animals were euthanized and fragments of the wound area, together with the edges were removed, fixed in 10% formaldehyde solution and processed for paraffin embedding. In the histological sections with 5 µm of thickness, were carried out immunohistochemical methods for detection of blood vessels (VEGF) and stained with hematoxylin and eosin for morphological analysis. Statistical analysis was done by ANOVA and Tukey test (p<0.05). RESULTS: Morphological analysis showed larger fibroblasts and a higher concentration of collagen fibers in days 7 and 14 in wounds treated with the angico extract. Morphometric analysis demonstrated a significant increase in the number of blood vessels in both the seventh and 14th days (p<0.01) in wounds treated with the angico extract. CONCLUSION: The angico alcoholic extract (Anadenanthera colubrina var. cebil) induces the acceleration of wound healing in skin wounds of rats.
