“…This line of thinking is due to the results obtained in other papers in which this material was used in dense form, as cited by other authors, for the repair of defects in arterial vessels, membranes, the urinary bladder and hard material [11][12][13][14][15] .…”

“…Whatever the cause, the healing of these defects follows a sequence of events that can be divided into three phases, in accordance with the morphological changes: the inflammatory phase, a repair phase and a remodelling one [8][9][10][11][12][13][14][15][16] . In the inflammatory phase, hematomas are formed and reorganized, platelet growth factors are released and tissue formed which is rich in progenitory cells derived from within the bone tissue itself and peripheral blood.…”

PURPOSE: To measure the healed areas of osteochondral defects produced in femoral condyles of rabbits filled with biopolymer sugar cane gel and to compare these with those of the control group at 90, 120 and 180 days. METHODS: A study was made of 16 New Zealand rabbits, 6 and 7 months old, weighing between 2 and 2.5 kg. Defects of 3.2 x 4 mm were made, with trephine, in the femoral condyles of the right and left knees. As to the study group defects of the medial and lateral condyles of the right knee were used which were filled with Biopolymer Sugar Cane Gel; as to the Control Group defects of the medial and lateral condyles of the left t knees were used which were left open for natural healing. The defects were analyzed at 90, 120 and 180 days after surgery. After euthanasia, the knees were removed and fixed in Bouin's solution for later digital photographic documentation with a digital camera. The areas healed were measured in both the study and control groups using the images obtained from an Image-J® program. Statistical analysis was conducted using the non-parametric Mann-Whitney test. RESULTS: There were no significant differences between the means of the healed areas in the study and control groups at 90, 120 and 180 days after surgery. CONCLUSION: The dimension of the healed areas of the defects treated with the biopolymer sugar-cane gel in the study group was similar to those of the control group, which healed naturally.

PURPOSE:To develop an experimental model of acute inflammation, like aphthous ulcers, in oral cavity of rabbits, and also, to evaluate the results of the application of a polysaccharide spongy film of molasses from sugar cane as assist treatment in the healing process. METHODS:Twenty adult rabbits weighting between 2.5 kg and 3.9 kg were divided into two groups: experimental and control infected ulcers were induced on the jugal mucosa by surgical excision. They were treated at the experimental group by curettage and dressing with spongy film of cellulosic polysaccharide film, whereas saline solution was used in the control group. Temporal evolution of the healing area, histopathology and bacteriological analysis were used to evaluate the healing process on the 3 rd (D3), 7 th (D7) and 11 th days (D11). RESULTS:The healing time and bacteriological study showed no statistical differences on the group means. Analyzing the histopathology of the experimental group we verified epithelial hyperplasia from D3 to D11, instead in the control group there was a greater clutter of the epithelial cells from the D3 to D11. CONCLUSION:The experimental model used caused aphthous ulcers and the polysaccharide sponge film can be used as an aid in the symptomatic treatment and healing of the ulcerative lesions of the oral mucosa.

“…Desta forma, promover a adesão de células a um biomaterial pode ajudar na integraçaõ do tecido conectivo mole com o implante, repercutindo no desenvolvimento de novas ferramentas (CARVALHO et al, 2010;MAGER et al, 2011;PIRES et al, 2015). Os biopolímeros despontam como biomateriais inovadores, em função da sua biocompatibilidade e o biopolímero de cana-deaçúcar (BCA), um exopolissacarídeo produzido a partir da fermentação do melaço pela bactéria Zoogloea sp., vem sendo utilizado em diversas aplicações nas áreas das Ciências da Saúde e da Biologia (PATERSON-BEEDLE et al, 2000;CASTRO, et al, 2004;AGUIAR et al, 2007;CAVALCANTE, et al, 2007;SILVEIRA et al, 2007;MAYER et al, 2011;MARTINS et al, 2013;SILVEIRA et al, 2014;ABREU et al, 2016).
