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

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

Retroviroses em felinos domésticos

The retrovirus are recognized as pathogenic group of virus for domestic animals. The particularitities of these viruses are the necessity of the enzyme transcriptase reversa, for the conversion of the viral RNA in viral DNA (provirus) and the incorporation in the DNA of the cell, what it confers to the infection the lifetime character, due to all the infected cells present the provirus our DNA. Among the retroviruses in domestic felines, the leukaemia and immunossupressive virus represent the more important diseases. The main form of transmission of the virus of the FeLV is occur by close contact and the saliva presents high viral concentration. For the FIV, the main form of transmission is represented by wounds of bite. The retrovírus, replicate mainly in high metabolization cells. The infection for FeLV cause mieloproliferativas and degenerative illnesses, while the FIV are related imunossupressora illness. The treatment for these retroviroses is symptomatic associated to imunomodulatory drugs, none of these drugs are capable to eliminate the virus. For the prevention of these retrovirus are used vaccines. However only the vaccine against FeLV have showed efficiency. Thus , the more important measures in control of these diseases is prevent the contact between infected and health felines. The ain of present study was reviewed the more important aspects of retroviruses in domestic felines, with emphasis to virulence properties, epidemiology, fisiopathogeny, clinical manifestations, methods of diagnosis, therapy, and control measures

Evaluation of stryphnodendron sp. release using natural rubber latex membrane as carrier

Natural rubber latex from Hevea brasiliensis has interesting characteristics related to this work such as: it is easy to manipulate, low cost, can stimulate the natural angiogenesis, is a biocompatible material and presents high mechanical resistance. The aim of this study was to develop a novel sustained delivery system for Stryphnodendron sp. based on Natural Rubber Latex (NRL) membranes and to study the Stryphnodendron sp. delivery system behavior. Stryphnodendron sp., commonly known as barbatimao is extensively used in folk medicine for the treatment of diarrhoea, gynaecological problems and for healing wounds. The stem bark of this species is mentioned in the Brazilian Pharmacopeia with a content of at least 20% of tannins. Previous studies showed significant cicatrizant properties, anti-inflammatory activity and gastric anti-ulcerogenic effects for the stem bark crude extract. One possible way to accelerate the tissue repair process, it was incorporated the Stryphnodendron sp. extract in NRL membranes. Stryphnodendron sp extract was incorporated into the NRL, by mixing it in solution for in vitro protein delivery experiments. Results show that the NRL membrane can release Stryphnodendron sp. for up to 49.89% of its Stryphnodendron sp. content for up 400 h. The kinetics of the extract release could be fitted with double exponential function, with two characteristic times of 0.78 and 133.22 h. In this study, we demonstrated that the induced angiogenesis provided by NRL membranes combined with a controlled release of extract is relevant for biomedical applications.

Casearia sylvestris Swartz Extract Release Using Natural Rubber Latex Biomembranes as Carrier

The Natural Rubber Latex (NRL) from Hevea brasiliensis has shown promise in biomedical applications due to its low cost, easy handling, mechanical properties and biocompatibility, being used for bone regeneration and wound healing due to its natural stimulus to angiogenesis. The aim of this work was to incorporate Casearia sylvestris Sw. extract in NRL biomembranes and study its release behavior. The complex membrane-extract has as object of study a new approach of using C. sylvestris extract in the treatment of wounds, for possessing antiseptic activity, anti-inflammatory and analgesic properties. The C. sylvestris species (Salicaceae), popularly known as "guaçatonga", presents great distribution and is used in folk medicine as antiulcer, wound healing, anti-snake venom, properties which have been proven and related to clerodane diterpenes (casearins A-X). The release rate of C. sylvestris compounds from extract-membrane complex was monitored and analyzed using the method of optical spectroscopy (UV-VIS). The release varied with temperature ranging from 14 to 33 days, releasing more than 90%, with an interesting and promising biomedical application, such as wound healing and burns.

Descrição do aparelho VABB (Vertically Activated Bite Block) para o tratamento da mordida aberta anterior

Nowadays, the correction of skeletal vertical dysplasia is considered a great challenge in Orthodontics. The skeletal open bite treatment presents limitations related to vertical growth pattern, the extension of open bite and especially the stability, which is very questioned. The treatment of skeletal open bite is mostly realized by the inhibition of vertical alveolar posterior development (relative intrusion) or absolute intrusion of posterior teeth, through vertical forces, generated by the action of masticatory muscles. The purpose of this article is to present a new appliance for the treatment of skeletal open bite, the VABB (Vertically Activated Bite Block) or modified Bite Block, whose action mechanism is to limit the vertical development of the molars, by the action of facial muscles and two bilateral expansion screws that provide a counterclockwise rotation of the mandible. It will also be presented a clinical case and the technical steps for the construction of this appliance.

Chitosan-alginate membranes accelerate wound healing

The purpose of this study was to evaluate the efficacy of chitosan-alginate membrane to accelerate wound healing in experimental cutaneous wounds. Two wounds were performed in Wistar rats by punching (1.5 cm diameter), treated with membranes moistened with saline solution (CAM group) or with saline only (SL group). After 2, 7, 14, and 21 days of surgery, five rats of each group were euthanized and reepithelialization was evaluated. The wounds/scars were harvested for histological, flow cytometry, neutrophil infiltrate, and hydroxyproline analysis. CAM group presented higher inflammatory cells recruitment as compared to SL group on 2nd day. On the 7th day, CAM group showed higher CD11b+ level and lower of neutrophils than SL group. The CAM group presented higher CD4+ cells influx than SL group on 2nd day, but it decreased during the follow up and became lower on 14th and 21st days. Higher fibroplasia was noticed on days 7 and 14 as well as higher collagenesis on 21st in the CAM group in comparison to SL group. CAM group showed faster reepithelialization on 7th day than SL group, although similar in other days. In conclusion, chitosan-alginate membrane modulated the inflammatory phase, stimulated fibroplasia and collagenesis, accelerating wound healing process in rats.

Mast cell concentration and skin wound contraction in rats treated with Brazilian pepper essential oil (Schinus terebinthifolius Raddi)

PURPOSE: To evaluate wound contraction and the concentration of mast cells in skin wounds treated with 5% BPT essential oil-based ointment in rats. METHODS: Twenty rats, male, of adult age, were submitted to skin surgery on the right (RA) and left antimeres (LA) of the thoracic region. They were divided into two groups: control (RA - wounds receiving daily topical application of vaseline and lanolin) and treated (LA - wounds treated daily with the topical ointment). The skin region with wounds were collected at days 4, 7, 14 and 21 after surgery. Those were fixed in 10% formaldehyde and later processed for paraffin embedding. Sections were obtained and stained by H.E for histopathology analysis. The degree of epithelial contraction was measured and mast cell concentration were also evaluated. RESULTS: The treated group showed higher mast cell concentrations (p<0.05) associated with increased contraction at day 7 and 14 respectively. CONCLUSION: Ointment containing 5% Brazilian pepper tree oil increases mast cell concentration and promotes skin wound contraction in rats.
