Evaluation of tissue reaction to Aroeira (Myracrodruon urundeuva) extracts: a histologic and edemogenic study

Objectives: This study evaluated subcutaneous tissue response to Aroeira (Myracrodruon urundeuva) extract employing edemogenic and histological analyses. Material and methods: Test groups consisted of aqueous and ethanolic Aroeira extracts and saline (control). For groups consisted of aqueous and ethanolic Aroeira extracts and saline Blue. After 30 min, the extracts and saline were injected on the dorsum of the rats, which were then sacrificed after 3 and 6 h. Readings were performed in a spectrophotometer. For subcutaneous implantation, 30 rats received a polyethylene tube containing the extracts on their dorsum and then they were killed after 7 and 28 days. The samples were processed for histological analysis and evaluated with a light microscope. The inflammatory infiltrate was quantified. Results: There were no statistically significant differences between aqueous extract and saline groups in relation to edema quantification in the different periods (p > 0.05). Ethanolic solution resulted in more edema independently of the experimental period (p < 0.05). Histological analysis showed similar results on the 7-day period for the 3 groups. There was a notable reduction on inflammatory cell number for saline and aqueous extract groups at 28 days. Conclusion: The aqueous extract showed biocompatible properties similar to those of saline.Coordenacao de Aperfeicoamento de Pessoal de Nivel Superior (CAPES)Coordenacao de Aperfeicoamento de Pessoal de Nivel Superior (CAPES

Neotropical Freshwater Fishes: A dataset of occurrence and abundance of freshwater fishes in the Neotropics

The Neotropical region hosts 4225 freshwater fish species, ranking first among the world's most diverse regions for freshwater fishes. Our NEOTROPICAL FRESHWATER FISHES data set is the first to produce a large-scale Neotropical freshwater fish inventory, covering the entire Neotropical region from Mexico and the Caribbean in the north to the southern limits in Argentina, Paraguay, Chile, and Uruguay. We compiled 185,787 distribution records, with unique georeferenced coordinates, for the 4225 species, represented by occurrence and abundance data. The number of species for the most numerous orders are as follows: Characiformes (1289), Siluriformes (1384), Cichliformes (354), Cyprinodontiformes (245), and Gymnotiformes (135). The most recorded species was the characid Astyanax fasciatus (4696 records). We registered 116,802 distribution records for native species, compared to 1802 distribution records for nonnative species. The main aim of the NEOTROPICAL FRESHWATER FISHES data set was to make these occurrence and abundance data accessible for international researchers to develop ecological and macroecological studies, from local to regional scales, with focal fish species, families, or orders. We anticipate that the NEOTROPICAL FRESHWATER FISHES data set will be valuable for studies on a wide range of ecological processes, such as trophic cascades, fishery pressure, the effects of habitat loss and fragmentation, and the impacts of species invasion and climate change.

Avaliação da resposta tecidual dos extratos vegetais aquoso e hidroalcoólico de araçá (Psidium cattleianum) pela análise edemogênica e morfológica em ratos

Atualmente, tem se verificado um grande avanço científico envolvendo os estudos químicos, farmacológicos e microbiológicos de plantas medicinais que visam obter novos compostos com propriedades terapêuticas. A demonstração de notável atividade antimicrobiana de extratos aquoso e hidroalcoólico de Araçá (Psidium cattleianum) sobre a microbiota bucal e a busca de substâncias que reúnam tais propriedades resguardando os princípios biológicos, nos levam a considerar uma possível utilização clínica desse extrato como coadjuvante na terapia odontológica. Desta forma, o objetivo deste estudo foi avaliar a resposta biológica imediata e tardia de soluções hidroalcoólica e aquosa preparadas à base de extrato vegetal de Araçá (Psidium cattleianum). Para a análise edemogênica (reação imediata), foram utilizados 18 ratos machos. Sob anestesia geral, os animais receberam injeção intravenosa de Azul de Evans 1%. Após 30 minutos, foi injetado 0,1mL de um dos extratos ou do controle (soro fisiológico), na região subcutânea dorsal do animal. Os animais foram sacrificados após 3 e 6 horas e as peças obtidas colocadas em formamida por 72 horas. A leitura foi realizada em espectrofotômetro com comprimento de onda de 630hm. Para a análise morfológica (reação tardia), 30 ratos receberam implantes de tubos de polietileno contendo os extratos ou o soro na região dorsal, e sacrificados após 7 e 28 dias. As peças foram processadas, cortadas e coradas com Hematoxilina e Eosina. Os resultados obtidos através da leitura dos espécimes em microscópio óptico, em aumentos de 10 e 40x, para avaliação da espessura da cápsula fibrosa e contagem de células inflamatórias, que quantificam o infiltrado inflamatório.Nowadays, it’s been seen great scientific advance involving chemistry, pharmacological and micro biotical researches in medicinal plants. These researches can find new components with therapeutic property. The demonstration of great anti micro biotic activity of watery vegetable and hydro alcoholic extract of araça (Psidium cattleianum) on the oral microbiota and the search form substances which can put together these properties keeping the biological principles, make us consider a possible clinical use of this extract as supporting on dentistry therapy. This way, the objective of this paper (research) was evaluate the biological immediate and late answer of hydro alcoholic and watery solutions prepared with vegetable extract of araça (Psidium cattleianum). For the edemogenic analysis (immediate reaction), we used 18 male mice. Under general anesthesia, the animals received intra shot of Evans blue 1%. 30 minutes later, it was injected 0,1mL of one of the extracts or the control (physiological serum), on the dorsal under skin region of the animal. The animals were sacrificed after 3 and 6 hours and the obtained material were put in formamide for 72 hours. The reading was made for spectrophotometer with waves length of 630nm. For the morphological analysis (late reaction), 30 mice received duct implant of polyethylene with the extracts or the serum on the dorsal region, and sacrificed after 7 and 28 days. The material were processed, cut and printed with HE. The obtained results from the reading of the species in optical microscopy, with raisings of 10 and 40x, for the thickness evaluation of the fiber capsule and counting of the damaged cells, that quantified the damaged infiltrate

Facial and dental injuries due to dog bite in a 15-month-old child with sequelae in permanent teeth: a case report

This article reports a longitudinal follow-up of a 15-month-old child with dental trauma resulting from an attack by a dog. The injury consisted of laceration of the facial tissues and loss of the upper central deciduous incisors, in addition to loss of bone tissue in the same area. A malformation of the crown of the right central permanent incisor and complete change of the shape of the left central permanent incisor were observed. The etiological factors of childhood injuries as well as the importance of dental emergency care are discussed and the 14-year clinical and radiographic follow up of the case is presented
