(Sociedade Brasileira para o Desenvolvimento da Pesquisa em Cirurgia, 2015-02) SILVA, Priscilla Flores; BRITO, Marcus Vinicius Henriques; PONTES, Flávia Sirotheau Corrêa; RAMOS, Suzana Rodrigues; MENDES, Laís Cordeiro; OLIVEIRA, Louize Caroline Marques
PURPOSE: To evaluate the effects of copaiba oil on jaw defects repair in Wistar rats treated with bioglass or adipose tissue. METHODS: A jaw defect was randomly created in forty-two rats and filled with bioglass or adipose tissue. The two groups (Gbio and Gcell) were subdivided in three subgroups with seven animals each according to gavage administration: control (distillated water), oil (copaiba oil) and melox (meloxicam). Euthanasia was performed after forty post-operative days. The bone formation was analyzed regarding the histological aspects. RESULTS: The osteoclasts activity was observed only in four subgroups (p=0.78). Regarding the osteoblasts presence, it was very similar between the subgroups, the difference was due to Gcell-melox (p=0.009) that presented less osteoblastic activity. The inflammatory cells were more evident in Gcell-melox subgroup, however, there was no difference in comparison with the other subgroups (p=0.52). Bone formation was observed in all subgroups, just two animals showed no bone formation even after 40 days. More than 50% of bone matrix mineralization was observed in 56% (23 animals) of the analyzed areas. The bone matrix mineralization was not different between subgroups (p=0.60). CONCLUSIONS: The subgroups that received copaiba oil showed bone repair, although not statistically significant in comparison to subgroups treated whit meloxicam or controls. Copaiba oil administered by gavage had no effect on bone repair in this experimental model.

Dentre plantas e mulheres: a porta de entrada do universo místico e poético que envolve mulheres em Salvaterra
(Universidade Federal do Pará, 2016) PEIXOTO, Lanna Beatriz Lima; SILVEIRA, Flávio Leonel Abreu da
In this present study we show preliminary reflections about the mythical universe involving women and female space in the Marajó region. We present data from the first two trips to the countryside, where we highlight two women in particular: Mrs.Marta in Joanes district, and Mrs. Joana, in a "quilombo", both located in the municipality of Salvaterra. Here, we expose some notes raised by the encounter with these two women, to think about their experiences from the dialogue with a specific bibliography. At first the existence of a common theme helped us we enter the universe of their daily lives and more directly from their yards, from where the knowledge related to medicinal plants have emerged as the tip of a ball, comprising memories and knowledge in around healing practices of shamanism and local mysticism, involving mainly the female figure we intend to address this during the discussion in this article.

Precisamos pisar no chão: plantas medicinais e ancestrais usos de práticas e saberes entre os quilombolas de Deus Ajude
(Universidade Federal do Pará, 2024-11-07) SOUZA, José Luis Souza de; CARDOSO, Denise Machado; http://lattes.cnpq.br/2685857306168366
This research is carried out in a traditional territory recognized as Deus Ajude and investigates the relationship between the use of medicinal plants and the Quilombola identity in this community, located in the Marajó archipelago, Pará, Brazil. Motivated by the debates on the preservation of Quilombola territories, especially after the constitutional recognition of traditional lands by Art. 68 of the ADCT (1988), this anthropological and sociological research examines how ancestral knowledge linked to the use of plants strengthens the Quilombola cultural identity and contributes to territorial conservation. With a population of approximately 300 inhabitants, the community makes sustainable use of a biodiverse area composed of forests that provide the use of their fruits, ancestral and medicinal plants, lianas and rushes, in addition to rivers with fish and other aquatic animals that make up a rich scenario with potential for the development of different activities. The research also analyzes the challenges imposed by the expansion of agribusiness on these territories and the replacement of traditional knowledge by modern pharmacological practices, highlighting the relevance of traditional knowledge for cultural resistance and environmental sustainability.

Recurso polínico coletado por abelhas sem ferrão (Apidae, Meliponinae) em um fragmento de floresta na região de Manaus - Amazonas
(Instituto Nacional de Pesquisas da Amazônia, 2009-09) OLIVEIRA, Francisco Plácido Magalhães; ABSY, Maria Lúcia; MIRANDA, Izildinha Souza
The objective of this study was to characterize the resources used by Amazonian bees Melipona seminigra merrillae, Melipona fulva, Trigona fulviventris and CephaloTrigona femorata, in an urban Forest patch at Manaus city from March to October 2001. The pollen analysis determined 90 pollen types, distributed in 31 families, 67 genera and 10 palynologycal types unidentified. Trigona fulviventris was the bee species that presented the most diversified pollen types, using 58 sources in that period. The size of pollen types used were distributed as follows: T. fulviventris (58), M.s. merrilae (41), C. femorata (34) and M. fulva (25). Plant species contributing the most for the diet of the bees and presenting the highest frequencies on the pollen samples were Miconia myriantha (12,91%), Leucaena leucocephalla (9,52%), Tapirira guianensis (6,53%), Eugenia stipitata (6,22%), Protium heptaphyllum (6,17%) and Vismia guianensis (5,93%). Generally the bees concentrated their collections on a reduced number of plant species and with a differentiated degree of use for each source. Pollen types with frequency above 10% occurred in a small proportion for most months, being responsible for more than 50% of all the pollen collected every month. Pollen source used varied according to the species, T. fulviventris had a more broad and diversified diet, whereas M. fulva was the bees species that least diversified its diet. T. fulviventris presented higher uniformity on the use of pollen sources and the pollen niches overlap was higher between M.s. merrillae and M. fulva and lower between T. fulviventris and C. femorata.
