Item Isolamento De Staphylococcus Spp. Multirresistentes Da Pele De Cães Saudáveis E Com Piodermite(Universidade Federal de Goiás, 2011-03-01) ALMEIDA, Greyciele Rodrigues de; ANDRADE, Maria Auxiliadora; http://lattes.cnpq.br/9441751521255467; DAMASCENO, Adilson Donizeti; http://lattes.cnpq.br/3900110295277130; SILVA, Olízio Claudino da; http://lattes.cnpq.br/7787082855013504Item Levobupivacaína, ropivacaína ou lidocaína na anestesia palpebral em equinos: avaliação da pressão intra-ocular, da produção lacrimal e da eficácia do bloqueio anestésico(Universidade Federal de Goiás, 2009-09-26) AMARAL, Andréia Vitor Couto do; SILVA, Luiz Antônio Franco da; http://lattes.cnpq.br/0446055905975647; CHAVES, Nilo Sérgio Troncoso; http://lattes.cnpq.br/9218281815823682Corneal anesthesia is required in order to evaluate the intraocular pressure (IOP) and eyelid blockades may also be necessary, using local anesthetic agents in horses. The aim of this study was to evaluate the IOP and the corneal touch threshold (CTT) at the central area of the cornea, after eyelid blockades with anesthetic 0.75% ropivacaine, 0.75% levobupivacaine and 2% lidocaine. Nine adult female animals of undefined breed horses, which received 2.0 ml of anesthetic for supraorbitary blockade and 2.5 ml for auriculopalpebral blockagde. All animals were anesthetized with the three anesthetic drugs, with an interval period of seven days between drugs, performing a Latin square 3x3x3. The IOP and CTT were measured before and 10, 20, 40, 60, 80 and 100 minutes after the blockades. The PIO was maintained within the limits considered normal in all three anesthetic drug groups evaluated. After 10 minutes, there was significantly CTT values decrease for all three anesthetics. The recovery time of CTT was higher in 30 the animals anesthetized with lidocaine than those anesthetized with levobupivacaine and ropivacaineItem Avaliação do desempenho, hematológica, bioquímica, parasitológica e histopatológica de bovinos de corte em sistema intensivo de produção(Universidade Federal de Goiás, 2010-03-04) COSTA, Gustavo Lage; SILVA, Luiz Antônio Franco da; http://lattes.cnpq.br/0446055905975647; ARAÚJO, Eugênio Gonçalves de; http://lattes.cnpq.br/3919777570059928; FIORAVANTI, Maria Clorinda Soares; http://lattes.cnpq.br/8772502020076257The profile of the Brazilian cattle industry has changed due to the search for more efficiency. It is transforming form extractive practices to new levels of intensification and productivity. In this context, the metabolic and parasitological profile of 39 crossbred animals, aged around 24 months at the time of entering the feedlot and prior to slaughter were performed, in order to assess the health of bovine finished in this breeding system. The following evaluations were carried out: hematology, biochemistry, histopathology and parasitology. The clinical biochemical evaluation consisted of the higidity assessment of the liver and kidney, comprising the balance of energy and protein of these animals. The parameters used were: ALP, AST, GGT, bilirubin (total, conjugated and unconjugated), total protein, albumin, globulin, urea, creatinine, cholesterol and triglycerides. Total proteins were fractionated by agarose gel electrophoresis. Parasitological assessment was done through EPG and stool culture. In histopathology fragments of liver, kidney, lynph nodes (mesenteric, pre scapular and pre femoral) and lung were observed. Alterations in biochemical and electrophoretic tests, suggestive of chronic liver disease, were found. Such alterations were noticed by the presence of foamy macrophages in the liver and mesenteric lymph nodes; however, these findings were not related to differences found in daily weight gain found. Histology did not show alterations suggestive of respiratory diseases.Item Gel de quitosana à 2% na cicatrização de feridas cutâneas em ratas diabéticas(Universidade Federal de Goiás, 2012-02-28) DIAS, Taís Andrade; REZENDE, Kênnia Rocha; http://lattes.cnpq.br/3337615895445199; FIORAVANTI, Maria Clorinda Soares; http://lattes.cnpq.br/8772502020076257; PAULO, Neusa Margarida; http://lattes.cnpq.br/7949273598509043Wound healing difficulty is one of the major complications of diabetes mellitus which makes the healing process slower and treatment more expensive. Chitosan has been studied regarding its ability to accelerate healing and tested in the treatment of skin lesions with impaired healing as diabetic ones. Fifty-four Wistar female rats were divided randomly in three groups with 18 animals each, which were subdivided into three subgroups (n = 6) corresponding to periods of post-operative evaluation (7, 14 and 21 days). All subjects underwent experimental induction of diabetes by single intraperitoneal application of alloxan with a dose of 120mg/kg. After the diabetic state was confirmed, the study proceeded to general anesthesia for the manufacture of skin wounds in the dorsal region of the animals. The control group (GC) received saline on the wounds. The GA group was treated with oil-based essential fatty acids and the GQ wounds were treated with 2% chitosan gel characterized and standardized for this study. Macroscopic, histological and histomorphometric analyses were performed to monitor the healing process of wounds. The healing of wounds treated with chitosan was faster than the healing in the other groups at 14 and 21 days postoperatively, and the control group presented the lowest percentage of wound contraction. Statistical difference was found at 14 days between GQ and GC in the macroscopic analysis (p=0,02). Histologically there was an advance in the GA and in the GQ reeptelization compared to GC at 7 and 14 days, as well as the presence of polymorphonuclear cells in GQ at seven days and mononuclear cells in the other groups in this period. Fibroblasts and collagen were showed to be predominant in all groups during the period of 21 days characterizing the final phase of healing. The methodology used to prepare a 2% chitosan gel produced a drug with technical qualities that are suitable for topical use. This treatment was satisfactory as it accelerated the healing of injuries when compared to animals treated with saline and essential fatty acids oil. The proposed protocol becomes a promising and economically viable alternative for the treatment of diabetic wounds.Item Expressão de mmp-2, mmp-9 e upar em próstatas caninas normais e c lesões proliferativas(Universidade Federal de Goiás, 2010-03-02) FALEIRO, Mariana Batista Rodrigues; DAMASCENO, Adilson Donizeti; http://lattes.cnpq.br/3900110295277130; BATISTA, Aline Carvalho; http://lattes.cnpq.br/0199082642322002; MOURA, Veridiana Maria Brianezi Dignani de; http://lattes.cnpq.br/8773201078957745Humans and dogs show dysplastic lesions in the prostate, such as prostatic intraepithelial neoplasms (PIN) and proliferative inflammatory atrophy (PIA), which are studied due to their malignance potential. The matrix metalloproteinases (MMP) are a family of proteolytic enzymes thought to play an important role in tumor invasion and metastasis in face of their ability to degrade the extracellular matrix (ECM) and basement membrane. The plasminogen activator (PA) system has been suggested to play a central role in cell adhesion, migration, wound healing, angiogenesis, inflammation, regulation of growth factors and tumor invasion. The receptor of plasminogen activator type activator (uPAR) is a component of the PA, with a range of expression in tumor cell and stromal cells. So, this study was aimed to evaluated the expression and correlation between MMP-2 (gelatinase A) and MMP-9 (gelatinase B) as well as the expression of uPAR in normal canine prostate tissue and also in tissue with proliferative disorders, including benign prostatic hyperplasia (HPB), PIA, PIN and carcinoma. And therefore establish relation among the role of these enzymes in the remodeling of the extracellular matrix (ECM) and in the process of tumor invasion and metastasis. For this, it was performed immunohistochemical staining in tissue microarray of 149 paraffin-embedded fragments of prostate tissue selected from 57 prostates of non-castrated adult dogs with or without prostatic diseases. A total of 298 cores were analyzed and it was made 363 diagnoses: 36 (9.9%) normal, 49 (13.5%) BPH, 132 (36.3%) PIA, 75 (20.7%) PIN and 71 (19.6%) carcinomas. It was observed differences in cytoplasmatic immunohistochemical staining by MMP-2 and MMP-9 antibodies in relation to the cell number and intensity of labeling of the acinar epithelial and stromal perilobular cells between normal tissue and in those with proliferative disorders. A correlation between MMP-2 and MMP-9 antibodies occurred just in canine prostates with PIA in relation to the number of labeled cells in acinar epithelium and perilobular stroma, as well as, the staining intensity in the perilobular stromal cells. In relation to uPAR, it was observed differences of immunohistochemical staining of uPAR antibodies in canine prostate. Likewise, there was over expression in dysplastic and neoplasic specimens, but not in normal and benign prostate tissue. A number of epithelial cells labeled for uPAR showed variation among the diagnoses, except between PIN and carcinoma. Less intensity of labeling was observed in acinar epithelial cells of normal prostates compared with PIA, PIN and carcinoma. However, in the normal cells and in those with PIA, there was a difference in the number of cells, as well as in the intensity of stromal labeling. The intensity of labeling of stromal perilobular cells was higher in the PIA. PIA-A (accentuated) and PIA-M (moderated) cells showed greater intensity staining stroma and stromal cells labeled for uPAR, respectively. Thus, this study concludes that there was variation in gelatinases and uPAR expression in canine prostate according to the lesion. Also, there was Less labeling in normal and BPH and higher in PIA, PIN and carcinoma prostate tissues. The correlation between MMP-2 and MMP-9 in canine prostates with PIA indicates that the inflammation likely influenced the activity of these enzymes with simultaneous increase in their expression. The uPAR high expression in inflammatory and neoplasic tissues suggests high ECM proteolytic activity in these situationsItem Graduação histológica e expressão de metaloproteinases (MMP-9 e MMP-2) e seus inibidores (TIMP-1 e TIMP-2) na glândula mamária canina neoplásica(Universidade Federal de Goiás, 2012-08-03) FERREIRA, Hugo Henrique; MORENO, Juan Carlos Duque; http://lattes.cnpq.br/8509640024284103; NARDI, Andrigo Barboza de; http://lattes.cnpq.br/5256503293611165; MOURA, Veridiana Maria Brianezi Dignani de; http://lattes.cnpq.br/8773201078957745In bitchs, mammary glands are the most common sites for the occurrence of neoplasms. To evaluate the biological behavior of these lesions is routinely employ descriptive histological methods that, combined with histological grading, help predict prognosis of these diseases. The imbalance between the amount of tissue matrix metalloproteinases (MMPs), proteolytic enzymes involved in physiological and pathological processes, and their inhibitors (TIMP), plays an important role in development and tumor invasion. To evaluate the biological behavior of some common types of breast tumor bitches this research was divided in two steps. The first one was correlating histological classification and degree of mammary neoplasms in bitches, and to correlating the degree of malignancy and tumor size. For this, 119 samples were evaluated in canine mammary tumors, all tumors were considered disorders of the growth of canine mammary gland, including neoplastic (benign and malignant) and non-neoplastic (hyperplastic changes). All tumors were classified and only the malignant were graded histologically and correlated with tumor size. It was concluded that the complex carcinoma is the most common cancer histological type and which has the lowest histological grade compared to other malignant tumor types. Further, neoplasms larger than five centimeters were predominantly malignant (92,3% or 12/13) and no correlation was observed between tumor size and histologic grade. The relation between histological classification and graduation helped in microscopic description of malignant mammary tumors in bitches. The second step was to evaluate the expression of MMP-9, MMP-2 TIMP-1 and TIMP-2 in normal and neoplastic canine mammary tissue. For this purpose it was selected 48 samples of canine mammary tissue, 14 complex carcinomas (CC), 13 tubulopapillary carcinoma (TC), six simple mammary adenoma (MA) and 15 normal breast (MN), and submitted to technical immunohistochemistry for the evaluation of the intensity staining and the number of epithelial and stromal cells selected. Differences were observed in the expression of MMP-9 and TIMP-1 and TIMP-2 according to the mammary histomorphology. The MMP-9 showed higher expression in epithelial and stromal cells of the CC and CT compared to MN. It was found a lower expression of TIMP-1 in stromal cells of the CC and overexpression of TIMP-2 in epithelial cells of the CT. Also a positive correlation between MMP-9 and TIMP-1 and the intensity staining and number of epithelial and stromal cells marked in MN and between MMP-9 and TIMP-2 on TC neoplastic epithelial cells. It was concluded that there is variation between expression of MMP-9, TIMP-1 and TIMP-2 among the tumor types, and a positive correlation between TIMP-1 and MMP-9 in normal mammary gland and between MMP-9 and TIMP-2 in tubulopapilar carcinoma. The balanced expression of MMP-9, MMP-2, TIMP-1 and TIMP-2 is essential for the homeostasis of canine normal mammary gland, while the overexpression of MMP-9 and TIMP-2, and the reduced expression of TIMP-1 in carcinomas represents an appropriate condition to the tumor development.Item Filme à base de quitosana comparado à gordura autógena na prevenção de aderências pós-laminectomia dorsal em coelhos(Universidade Federal de Goiás, 2009-01-30) GOMES, Filipe Augusto Sales; DAMASCENO, Adilson Donizeti; http://lattes.cnpq.br/3900110295277130; PAULO, Neusa Margarida; http://lattes.cnpq.br/7949273598509043The adhesions formation after surgical procedures in the spine is a subject well studied in neurosurgery, according to the discomfort and postoperative pain suffered by patients. Several studies have been performed using anti-inflammatories, autologous grafts, xenografts and xenologer biomaterials and even in film form and gel with the aim of reducing or preventing adhesion formation. The aim of this study was to compare the film based on chitosan with autogenous fat in preventing dural adhesions in rabbits. This technique was compared to the technique used routinely by neurosurgeons who, in most cases, using autogenous fat. We used 24 adult male rabbits of New Zealand, and 15 and 30 days postoperatively (PO) the spinal cords of animals underwent myelography and histological evaluation. The animals were randomly divided equally into two groups (group G and Q), and further subdivided into four subgroups: G15, Q15, G30 and Q30 according to time points and the material used. In the group Q, a laminectomy performed between L1-L2 was occluded with the film based on chitosan and in the Group G the defect was repaired with autogenous free fat graft. In assessing myelography, there was a moderate compression of the column spinal cord both in group G as in group Q. In two rabbits of group Q the compression was attributed to severe disruption of the stabilization made with surgical steel wire. There was no significant difference (p ≤ 0.05) between groups and subgroups. After the pre-established postoperatively, fibrous adhesion from mild to intense between the dura and the implant was noted in animals from both groups, with fibrosis and collagen fibers interspread with the tissue and implant withought, no statistically significant difference (p ≤ 0.05) between groups and subgroups. There were cell infiltrates and giant cells that were more intense in the group Q. At 15 and 30 days postoperatively, the films based on chitosan were coated by inflammatory cells with areas of central necrosis. At 30 days postoperatively, the material had a fibrous capsule surrounding the inflammatory focus and the implant was noticed statistically significant (p ≤ 0.05) of 5% when comparing the groups and subgroups. Based on the results we can conclude that the film based on chitosan, as well as a free autogenous fat reduces the extent of dural adhesions in rabbits, however, the film based on chitosan as well as any foreign body, induces crhonic and intenses inflammatory responses in the rabbitItem Ultrassonografia da extremidade distal dos membros de bovinos em desenvolvimento(Universidade Federal de Goiás, 2012-07-27) GONÇALVES, Pryscilla Vanesa Rodrigues; CUNHA, Paulo Henrique Jorge da; http://lattes.cnpq.br/3363890096623194; SILVA, Luiz Antônio Franco da; http://lattes.cnpq.br/0446055905975647; BORGES, Naída Cristina; http://lattes.cnpq.br/9181279951885005The clinical manifestations of diseases of the locomotor system generates discomfort and pain, which can trigger lesions, the severity of which provides an abnormal distribution of weight, resulting in overloading joints, tendon and ligaments. Imaging studies are presented as a valuable tool to evaluate the degree of impairment of digital anatomical structures. The objectives of this study were carrying out a literature review on the applications of ultrasound in the distal ends of the locomotor limbs cattle and describe the sonographic anatomy of the structures that make up the metacarpo/ metarsophalangeal and interphalangeal joints, measuring the superficial digital flexor tendon (SDFT) and deep (DDFT) of young cattle during three stages of growth. Were employed nine Nelore calves and seven Girolando. During 120 days, the animals were managed intensively, they were weighed and subjected to clinical, radiographic and ultrasound with eight, ten and twelve months. In the clinical evaluation of the 64 distal ends, it was found that 37 (57%) showed horizontal lines of stress. Radiography of the three moments revealed no bone lesions. The measures taken by ultrasonography cross-sectional thickness of the SDFT and thickness and width of DDFT were similar (p ≥ 0.05) between the breeds, and SDFT for the minimum and maximum values observed for Nelore (lateral: M0 = 1.98 ± 0.24 mm, M2 = 2.83 ± 0.27 mm and medial M0 = 1.98 ± 0.20 mm, M2 = 2.66 ± 0.13 mm) and for Girolando (lateral: M0 = 1 , 97 ± 0.20 mm, M2 = 2.54 ± 0.14 mm and medial M0 = 1.90 ± 0.13 mm, M2 = 2.57 ± 0.12 mm). For DDFT the following minimum and maximum values observed for Nelore (lateral thickness: M0 = 5.53 ± 0.76 mm, M2 = 7.07 ± 0.36 mm/lateral width: M0 = 12.98 ± 1.18 mm; M2 = 15.33 ± 0.40 mm/medial thickness: M0 = 5.38 ± 0.68 mm, M2 = 7.21 ± 0.31 mm medial/width: M0 = 13.49 ± 1.10 mm, M2 = 15, 52 ± 0.50) and for Girolando (lateral thickness: M0 = 5.23 ± 0.78 mm, M2 = 6.93 ± 0.18 mm/lateral width: M0 = 12.57 ± 0.93 mm, M2 = 15 , 46 ± 0.46 mm/medial thickness: M0 = 4.70 ± 0.43 mm, M2 = 7.00 ± 0.37 mm medial/ width: M0 = 12.84 ± 0.98 mm, M2 = 15.28 ± 0 56). The structures visualized by ultrasound examination of the dorsum of the distal epiphysis of the metacarpus/ tarsus, were longitudinal growth plate, the condyles of the metacarpal/tarsal bones, joint capsule, common extensor tendon of the third finger and the joint space. In the interphalangeal region was observed the extensor tendon of the third finger and medial extensor, proximal, middle and distal phalanges and the joint space. In the palmar/plantar portion of metacarpal/ tarsophalangeana joint were observed the median and metatarsal plantar arteries, SDFT, DDFT, digital tendon sheaths, joint recesses and interosseous muscle. Distal to the dorsal region of dew claw was observed the annular digital distal ligament and in reversal of the positioning between the SDFT and DDFT. The sonographic characteristics observed on examination of the distal end of bovine Nelores and Girolandos aged between eight months and one year are indicated for satisfactory identification of these structures for cattle with similar characteristics, as well as measurements of thickness and width of the SDFT and DDFT values are reference to cattle of these ages.Item AVALIAÇÃO HISTOLOGICA DE PULMÃO DE BOVINOS DA RAÇA NELORE TERMINADOS A PASTO E EM CONFINAMENTO.(Universidade Federal de Goiás, 2009-02-13) RAMOS, Beatriz Peixoto; FIORAVANTI, Maria Clorinda Soares; http://lattes.cnpq.br/8772502020076257; ARAÚJO, Eugênio Gonçalves de; http://lattes.cnpq.br/3919777570059928; VIEIRA, Dirson; http://lattes.cnpq.br/1077620544105284Most Brazilian states have common features, as the problems that affect the health of animals. Infectious and contagious diseases, parasites, and metabolic deficiencies, are of great importance, directly interfering in economic indicators. Respiratory diseases have highlighted the various systems of breeding cattle, because they have lung particular characteristics making them more vulnerable to diseases of the respiratory system. There are no confirmed reports that in feedlot of dirt would be a case of pneumonia higher compared to other systems to create due to the high population density, stress and dust. Therefore, the objective of this project is to assess the level of changes in lung tissue of cattle Nelore finished under confinement conditions compared to the finished under grazing. We used 96 animals, 48 animals raised on pasture (AP) and 48 animals from confinement (AC). These were identified in the corral of waiting, with the slaughter line and perform a collection of fragments of the cranial lobe and the median on the ramp inspection. The samples were fixed in buffered solution of formol 10%, preserved in alcohol at 70% and histological processed, making the color of slides with hematoxylin and eosin (H&E) and the optical microscope analysis. Initially the data were submitted to descriptive statistics and later to the chi-square, Wilcoxon and Mann-Whitney. None of the evaluated parameters was influenced by the different lobes and different systems of terminationItem Telas depolipropileno revestidas por quitosana/polietilenoglicol na ocorrência de aderências peritoniais: Estudo experimental em ratas(Universidade Federal de Goiás, 2011-02-25) RODRIGUES, Danilo Ferreira; MELO, Renato Miranda de; http://lattes.cnpq.br/2028648748702062; MENEZES, Liliana Borges de; http://lattes.cnpq.br/2012543423092393; PAULO, Neusa Margarida; http://lattes.cnpq.br/7949273598509043Peritoneal adhesions are highly important in clinical and surgical practice because of the potential to cause sequelae such as chronic abdominal pain, infertility and bowel obstruction; thus, preventing the formation of this process becomes a challenge for surgeons. Due to biocompatibility, bioabsorption, healing and antimicrobial properties, chitosan is a polymer which has aroused interest of researchers studying the prevention of peritoneal adhesions. The objective of this research was to determine whether the intraperitoneal implantation of polypropylene mesh coated with a film of chitosan/polyethylene glycol is effective for the prevention of adhesions in rats with induced abdominal defects. We sought to further characterize the tissue reactions in acute and chronic phases of the inflammation process, and the tissue repair processes triggered by this biomaterial and the polypropylene mesh without coating. Defect of about 1cm was made in the abdominal wall, with reference to anatomical aponeurosis of the fascia of the rectus abdominis and obliquus externus abdominis muscles, followed by the implantation of polypropylene meshes coated with chitosan / polyethylene glycol (QP Group, n= 12) and uncoated polypropylene meshes (PP group, n= 12). Six animals from each group were euthanized at four and 45 days after implantation and the involvement of the mesh area by the adhesion, the type of adhesion, the inflammation process and tissue repair, and the quantification and characterization of collagen fibers were evaluated. The average of the meshes involved by adhesions in the QP and PP groups was 39.088% and 84.024%, respectively, and the structure involved in abdominal adhesions in the QP group usually consisted of the omentum around the implant, while in the PP group, adhesions were usually on the surface of the mesh. After four days of surgery, the amount of mononuclear cells was lower in QP, but the amount of polymorphonuclear cells, fibrin and collagen fibers was in greater quantity in this group; besides, the later variable showed better spatial organization. After 45 days of biomaterials implantation, there was a reduction in the amount of inflammatory cells, and spatial organization of collagen fibers in the QP group remained strong. It is concluded that the meshes coated with the film based on chitosan/polyethylene glycol did not prevent adhesion formation, but significantly minimized the seriousness of this process. In the acute phase of inflammation and tissue repair, the foreign body reaction was less intense in the group receiving the coated polypropylene mesh, but the tissue reactions caused by the studied biomaterials were similar to the chronic phase. The mesh coated with film-based chitosan/polyethylene glycol stimulated higher production and better orientation of collagen type I in the acute phase of inflammation and tissue repair, and better orientation of collagen fibers in the chronic phase of this process.Item Implante intraperitonial de tela de polipropileno revestida de hidrogel de poli (2-hidroxietil metacrilato) em cães aspecto histológico(Universidade Federal de Goiás, 2010-10-24) SILVA, Daniel Barbosa da; MOURA, Veridiana Maria Brianezi Dignani de; http://lattes.cnpq.br/8773201078957745; PAULO, Neusa Margarida; http://lattes.cnpq.br/7949273598509043Abdominal wall defects may occur in fairly all animal species, and frequently demand corrective surgical treatment including implants of meshes, such as polypropylene. However, this biomaterial is not free from complications, what stimulates constant researches for new biomaterials that present certain advantages. Due to its well known biocompatibility, poliHEMA hydrogel was the chosen biomaterial for experimental abdominal wall implant associated to polypropylene mesh. This essay compared tissue responses to the employment of polypropylene mesh alone (group PP) and polyHEMA Hydrogel film associated to polypropylene mesh (group PH) on the correction of induced abdominal wall defects on bitches. Twelve mongrel adult female dogs, weighting from 10 to 20 kg, were divided in two equal groups. The animals from group PP received the polypropylene mesh implant whilst those from group PH received polyHEMA hydrogel coated polypropylene mesh to replace the abdominal transverse muscle. Six animals from each group were submitted to surgical procedure to remove the meshes at 30 and 60 days of the postoperative period. Tissue repairing phenomena such as: chronic inflammatory reaction, giant cell presence (foreign body chronic granulomatous inflammatory reaction) and connective tissue proliferation were microscopically evaluated. It may be concluded that polyHEMA hydrogel as a coating agent on polypropylene mesh implanted onto abdominal wall of female dogs triggers greater deposition of type I collagen, than polypropylene mesh alone.Item Parâmetros hematológicos e bioquímicos da tilápia-do-nilo (Oreochromis niloticus L.) sob estresse por exposição ao ar(Universidade Federal de Goiás, 2010-03-02) SILVA, Roberta Dias da; VIEIRA, Dirson; http://lattes.cnpq.br/1077620544105284; FIORAVANTI, Maria Clorinda Soares; http://lattes.cnpq.br/8772502020076257The present study evaluated the hematological and biochemical parameters of adult tilapia (Oreochromis niloticus) under the influence of the physiological stress factor in animals submitted to air exposure during fattening in raceway system. Blood cell count, hemoglobin, hematocrit, mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH), mean corpuscular hemoglobin concentration (MCHC), leukogram, differencial leukocyte count, platelet, glucose, total protein, cholesterol, triglycerides and electrolytes (calcium, chloride, sodium and potassium) were analyzed. The results showed a uniform distribution for red blood cells, hematocrit, hemoglobin, secondary Wintrobe indices, total protein, glucose, cholesterol, and serum ions, indicated by a relatively low variation coefficient. There was positive correlation only for total white blood cells, organic defense cells (neutrophils and lymphocytes), glucose, cholesterol, sodium and calcium. As for the leukocytes (WBC), as the animals were exposed to aeration, the number of leukocytes gradually decreased (leukopenia), simultaneously occurring neutrophilia and lymphopenia. The glycemic index was a good indicator of physiological stress due to hyperglycemia (82.0 + 20.88 mg/dL) demonstrated in the treatments. The air exposure constituted an imbalance factor at the ion homeostasis and at the endogenous cholesterol synthesis. Besides, the recovery time did not result in the complete physiological rehabilitation face the imposed challengeItem Obesidade em cães: aspectos ecodopplercardiográficos, eletrocardiográficos, radiográficos e de pressão arterial(Universidade Federal de Goiás, 2009-02-27) TÔRRES, Andréa Cintra Bastos; FIORAVANTI, Maria Clorinda Soares; http://lattes.cnpq.br/8772502020076257; ARAÚJO, Eugênio Gonçalves de; http://lattes.cnpq.br/3919777570059928; ALVES, Rosangela de Oliveira; http://lattes.cnpq.br/5593911382353878The obesity is a morbid condition commonnly incident in veterinary practice, generally associate to the companion animals reduction of time and quality of life. This factor, added to the regularity that it is observed, makes from obesity, nowadays, the most important metabolism disease in dogs, being still able to promote serious health problems, including cardiovascular disorders. For this study, 14 medium-sized neutered mongrel adult female dogs were divided in two groups and submitted to a program of weight gain. Group I, presenting highest percentage of weight gain (average 21.4% above the initial weight, in average) and Group II, with shortest weight gain percentage (15% above the initial weight, in average). Afterwards, both groups were submitted to a obesity correction food program, to reach the initial weight. During the food programs, in the initial phase (T1), obesity phase (T2) and final phase of weight reduction (T3), examinations carried out were: electrocardiographic, radiographic and mensurations of the blood pressure. During the phases T2 and T3, ecodopplercardiographic examinations of all dogs were also performed. At the end of the experimental phase, every variables obtained were statistically evaluated, comparing the groups and the different phases within the same group. The results revealed no significant eletrocardiographic and ecodopplercardiographic alterations, considering up to 21% of increment on body weight; increase of cardiac silhouette on radiographic evaluation during the obesity phase and decrease after the weight loss, and increase of arterial systolic pressure after the weight increment.Item SUTURA COM POLIGLACTINA 910 E GRAMPOS DE TITÂNIO: aspectos urinários e urolitogênicos na ileocistoplastia experimental em cães(Universidade Federal de Goiás, 2009-02-06) UCHÔA, Gabriela Silva; PAULO, Neusa Margarida; http://lattes.cnpq.br/7949273598509043Urinary disorders are an important discovery in the ileocystoplasties, especially uroliths and bladder crystals, and are partially related to the kind of material used the in suture itself. The purpose of this study is to verify if there are differences regarding the formation of uroliths or bladder crystals after dogs ileocystoplasties practices involving sutures using unabsorbed titanium staples and sutures with polyglatine 910, observing the impact of the procedure in the renal function, modifications in the urinary constituents and differences in the surgery time duration between the groups. For that, two experimental groups of animals, each one with six, have been considered. In one group it has been used a polyglactin 910 suture thread (group A) and in the other, a titanium stapler (group B). In each animal of both groups there was selected a terminal ileac segment with approximately 5 cm for bladder augmentation. In group A, a suture of the detubularized ileum segment in bladder was executed using a polyglactin 910. In group B, the bladder augmentation with the selected ileac segment was done by linear cutter stapler using titanium staples. It was observed the presence of struvite crystals in both groups, in 11 animals of the experiment. In group A the operation duration was longer if compared to group B . It was also observed the formation of urinary mucus in great quantity in all animals in the post-operation first days. It was confirmed the formation of calculi in two animals, one in each experimental group, but in the group A animal the calculi was free from lumen and in the group B animal the stone was adhered to the stapling zone, attached to a staple that got exposed to direct contact with the urine. In the parameters verified in the urinalysis, urea and seric creatinine there was no sign of renal alteration and in the verification of blood count, no alterations were noticed or considered significant. It was possible to conclude that no significant differences were observed between the groups as for the formation of urinary stones and crystals in ileocystoplasties after 100 days. If compared to group B , Group A presented a longer operation and there were not evidences of alteration in the renal function in any phase of the experiment in both groupsItem Anestesia epidural toracolombar com lidocaína a 2% ou lidocaína hiperbárica a 5% pelo uso de cateter epidural totalmente implantado em cães(Universidade Federal de Goiás, 2012-02-24) VILLELA, Ana Carolina Vasques; BORGES, Naída Cristina; http://lattes.cnpq.br/9181279951885005; ALVES, Rosangela de Oliveira; http://lattes.cnpq.br/5593911382353878; MORENO, Juan Carlos Duque; http://lattes.cnpq.br/8509640024284103
