Avaliação histológica do processo de reparação do tecido ósseo do rato frente à aplicação de um adesivo à base de cianoacrilato

This research objective was to verify the tissues reactions obtained, in surgical experimental bone defect, after the etil cyanoacrylate chemical adhesive application in rats parietal bones. 1t was investigated the acceptance or no acceptance of the tissues surround the bone defect in which was placed the etil cyanoacrylate and the control bone defect. The specimens were submitted to light microscopic analysis. 24 adults rats were used (Rattus norvergicus, albinus, Wistar) with the average weight to 300 gr. and were divided in two groups: treated and control. After the bone defects were realized, etil cyanoacrylate was placed over one of the defects at the parietal bone (treated group). On the other defect nothing was placed and it was used like control group. After 24 hours, 3,5,7,30 and sixty days after surgery, for animals of each group were sacrificed. The bone samples were removed and fixed in 10% formalin during 72 hours and analyzed using light microscopy. The results showed that the acute inflammatory responses was more observed at lhe treated group than the control group. The chemical adhesive was observed until 60 days follow the surgery and the tissues around it present normal appearance. The chemical adhesive, etil cyanaocrylate, did not impede at the bone repair process

Avaliação da atividade anti-inflamatória e antinociceptiva do extrato hidroalcoólico de Eugenia punicifolia (Kunth) DC

Inflammation is an immune complex-related tissue damage and / or cell caused by chemical, physical, immunological or microbial. The inflammatory process involves a complex cascade of biochemical and cellular events, including awareness and receptor activation, lysis and tissue repair. In general, tissue damage trigger a local inflammatory response by recruiting leukocytes, which release inflammatory mediators. These substances are able to sensitize nociceptors. After synaptic transmission and signal modulation by nociceptive sensory neurons, these signals are perceived as pain. Pain is an experience that involves multiple factors. The route of the supraspinal pain control originates in many brain regions, such as substance periarquedutal gray (PAG), median raphe nucleus and rostral ventromedial medulla (RVM) and have a critical role in determining the chronic and acute pain. Anti-inflammatory drugs (NSAIDs) are used to control inflammation, which inhibit the inflammatory mediators, but can cause side effects such as stomach ulcers and cardiovascular damage. An alternative for the treatment of pain and inflammation is the use of plant species. The genus Eugenia belongs to the family Myrtaceae, one of the largest botanical families of expression in the Brazilian ecosystems. From the pharmacological point of view, studies of similar species crude extracts showed the presence of anti-inflammatory, analgesic, antifungal, hypotensive, antidiabetic and antioxidant activity of some species. As a class of importance in therapeutic phytochemical, the flavonoids has represented an important group with significant anti-inflammatory and gastroprotective, and are present in a significant way in the chemical composition of genus Eugenia. The project´s overall objective is to evaluate the antinociceptive and anti-inflammatory activities from hydroalcoholic extract of leaves of Eugenia punicifolia (EHEP). In this work we performed acute toxicity ...

Biotecnologias aplicadas à reprodução de éguas velhas

The acceptance of biotechnology for the most equine breeders association had a significant effect in the horse industry, gaining popularity around the world, because the increasing on the genetic gain, allowing the use of sub fertile mares and stallions with high genetics value on reproduction. The embryos in vitro production of human and cattle has been used with success, however in vitro embryo production is not efficient in the horse, as oocyte transfer (OT) and intracytoplasmatic sperm injection (ICSI). The oocyte transfer has been used especially in subfertile old mares presenting reproductive pathologies as: endometrite, cervical and uterine adhesions, blocked oviduct, perineal laceration and ovulation failures. During oocyte recovery process, the oocytes must be collected from immature follicles that need be matured in vitro or in vivo matured oocytes from pre-ovulatory follicles through the transvaginal aspiration guided by ultrasound. The recovered oocyte is transferred to a previously inseminated recipient mare, through the flank laparotomy. The intracytoplasmatic sperm injection (ICSI) is a procedure of in vitro fertilization that needs only one sperm that is aspirated and injected inside the oocyte. The oocytes used, can be from mature and immature follicles. Fresh, cooled and frozen semen can be used, because the procedure not requires a functional sperm. The use of Piezo drill resulted in a breakthrough the pellucid zone, allowing the vibration per minute provided in the sperm injection pipette, a major result of cleaved oocytes, due to a better sperm injection in the oocyte. The embryo transfer can be straight inside the oviduct, as also transcervical transferred after embryo culture produced in vitro. In conclusion both procedures (OT and ICSI) are effective to be used on equine assisted reproduction, getting results even lower than expected, but satisfactory from animal genetically superior
