Laserterapia em lesões de coluna na Medicina Veterinária

Lasertherapy is a method of non-pharmacological treatment and surgery that can be used in several injuries and in various tissues, from bone fractures to tendonitis, skin wounds and damaged nerves, permitting the recovery of these structures and their functions without causing any side effects. Laser therapy aims to restore patients that suffered various injuries, such as bone fracture, inflammation, edema, tendon rupture, spinal cord injury, among others, without invasive intervention, and the results obtained in several studies and case reports have proven the high potential of this therapy to become an official treatment of various pathological changes

Estudo farmacognóstico e avaliação da atividade farmacológica do extrato hidroalcoólico de Polygonum acre (erva-de-bicho)

O Brasil possui um enorme potencial de plantas medicinais usadas popularmente e ainda pouco estudadas pela comunidade científica. Dentro da família Polygonaceae, destaca-se a espécie Polygonum punctatum Ell., conhecida popularmente como erva-de-bicho, acataia, cataia, capiçoba, pimenta-do brejo ou pimenta-da-água. Essa espécie é perene e encontrada em lugares úmidos ou inundados, desenvolvendo-se preferencialmente em solo de boa fertilidade, areno-argiloso ou argiloso e com bom teor de matéria orgânica. É originária da Ásia e encontra-se aclimatada no Brasil em todos os Estados, particularmente no Rio Grande do Sul, Sul e Sudeste (LOPES et al., 2003). Há relatos de que na medicina popular faz-se o uso de todas as partes da planta para as mais diversas finalidades, tais como: antidisentérica, antisséptica, detersiva, diurética, antitérmica, anti-reumática, vermífuga e excelente cicatrizante de feridas e úlceras. E que por ser fortemente emenagoga e abortiva, seu uso não é recomendado para gestantes (MORGAN, 1984). Dentre as propriedades terapêuticas relatadas, destaca-se também o uso no tratamento de problemas circulatórios, visto que ela estimula a circulação e diminui a fragilidade capilar, e que por isso, apresenta um efeito hemostático bastante útil no tratamento de hemorróidas (TESKE e TRENTINI, 1995). No entanto, plantas medicinais utilizadas popularmente necessitam de estudos científicos que comprovem sua eficácia, segurança e qualidade. A espécie Polygonum acre H.B.K. (sinonímia de Polygonum punctatum Ell) possui poucos estudos científicos comprovando essa vasta utilização na medicina popular, sendo assim, se faz necessário estudar atentamente seus extratos e óleos essenciais, bem como associar a estes, estudos fitoquímicos e de identificação anatômica e morfológica para que não haja problemas que comprometam a qualidade e a eficácia...

Principais aplicações terapêuticas da ozonioterapia

The ozone therapy is the therapeutic administration of ozone, which can be: subcutaneous (SC), intramuscular (IM) Intradiscal; intracavitary (pleural and peritoneal spaces); intravaginal, intrauretral, in the bladder; ozonated autohemotherapy. This therapy is being increasingly studied in order to help in some treatments and is being proven to be very effective in most cases, especially in acting on disinfection and healing of extensive wounds. There are over 6000 articles on the medical use of ozone in the literature, but the concentration used varies with each author. Most diseases have a positive response because ozone increases tissue oxygenation and metabolism. Discovered in Germany in the nineteenth century, ozone therapy still needs further study to clarify its mode of action and demonstrate its benefits. The objective of this review is to discuss some of the studies in the literature and try to clarify the main directions and forms of action of ozone therapy in medicine, showing the possibilities of getting good results including in veterinary medicine

Avaliação da espessura do osso parietal como região doadora de enxertos ósseos.

Introduction: The study of graft donor sites, whether from the anatomical, physiological or morphological point of view, has become a topic of current interest, due to the increasing number of patients needing facial bone reconstruction for various reasons. Purpose: In view of the need to constantly improve surgical techniques for autogenous bone graft harvesting, still considered the best choice for facial bone reconstruction, this paper describes an anatomical study on dry skulls in order to evaluate the average thickness of the parietal bone. Material and Methods: Measurements of this bone were taken with a goniometer, at four previously defined points, in the region that is often used as a donor site, in 49 dry skulls (98 parietal bones). The results were evaluated using the T test. Results: Thickness was measured at four predetermined points. The mean values (Point A = 4898mm, B = 4517mm, C = 6185mm, D = 4280mm) show that the bone can be even thinner than previously reported in the literature in other studies of the same nature. The largest bone thickness is in the medial and posterior region. Conclusion: A knowledge of these anatomical characteristics is helpful in preventing possible surgical complications, as well as making it safer for the surgeon to remove this graft and providing more information on whether or not to indicate this region as a bone graft donor site.

Estudo histomorfométrico do processo de cicatrização óssea em defeitos cirúrgicos de camanho crítico em calvárias de ratos preenchidos com polímero de mamona

Objectives: The aim of this study was to evaluate the behavior of the polymer histomorphometrically castor during the healing process of defects of critical size calvarial preparations in rats. Materials and Methods: Twenty animals underwent a surgical procedure that was to be held in the calvaria of each animal a critical defect of 8 mm in diameter with a drill trephine. The rats were divided into two groups according to the following procedures: group C received no treatment and the bone defect site was filled with blood clot, group M, the bone defect was filled with castor oil polymer particles. The animals were sacrificed 180 days after the surgical procedures. After routine laboratory procedures the specimens were subjected to analysis histomorphometric. Results: In groups C the newly formed bone tissue was well developed, with adjacent areas of osteoid matrix rich in osteoblasts, and restricted to the vicinity of the edges of the defect. In animals of group M was observed newly formed lamellar bone tissue restricted to the vicinity of the defect edges and particles of polymer Castor distributed throughout the defect. There was a higher percentage of newly formed bone area was statistically significant in group C compared to animals in group M. Conclusions: Within the limits of this study can conclude that the castor oil polymer is biocompatible and had kept the area during the healing of critical size defects in surgically prepared rat calvariae.

Reação do tecido conjuntivo subcutâneo de ratos ao implante de Artglass®: estudo histológico

Indirect composite resin systems have been routinely recommended for making restorations in distressed patients. The purpose of this study was to evaluate histologically in rats the effect of chronic stress on the reaction of subcutaneous connective tissue after implant of Artglass™. For this purpose, 60 rats were divided into four groups (GI (control), GII (stressed), GIII (Artglass™) and GIV (Artglass™. / stressed) received dorsal subcutaneous implants of polyethylene tubes containing saline solution (GI and GII) or Artglass™ (GIII and GIV). In groups of four animals were sacrificed at 7,14 and 28 days postoperatively. The results allowed to observe more intense inflammatory reaction and tissue organization later in the animals subjected to stress.

Efeito do estresse crônico e benzodiazepínicos no reparo ósseo: estudo histológico em ratos

Stress is an environmental factor that may predispose individuals to depression. Benzodiazepines have been prescribed as effective drugs in these situations. The purpose of this study was histological evaluate of the effect of chronic stress and benzodiazepine drugs on bone healing. Bone cavities were created in both tibias of 40 male rats were divided into two groups: Control and Treaty. In this, the stressor stimulus was applied 40 days pre-operative and all post-operative days until sacrifice in the morning for 2 hours, by immobilizing restraint. These animals also received diazepam benzodiazepine group, daily, at a concentration of 5mg/Kg/peso body within 15 days of preoperative. In groups of five animals were sacrificed at 7, 14, 30 and 60 days post-surgery. At 7 days postoperatively, while the control group exhibited tissue rich in fibroblasts, the treated group showed newly formed tissue with few fibroblasts and capillaries along with lymphocytes and macrophages. At 14 days postsurgery, the control group showed newly formed trabecular bone while the treated group progressed to thin trabecular bone with numerous osteoblasts on their borders. At 30 days post-operative bone healing is complete in both groups. At 60 days post-operative characteristics observed in the treated and control groups are similar to the previous period, but with more advanced osteogenesis.
