Curraleiro breed has adapted to the extensive breeding in the Brazilian savanna. These rustic animals seem to be more resistant to regional endemic diseases. Resistance to infection is directly correlated to the host immune response. In order to check if differences might exist among Curraleiro s immune response and the response of other exotic cattle breeds in the savannah region, Curraleiro and Nellore calves were assessed before and after immunization with BCG vaccine. Twelve young calves (around six months of age) were used. After quarantine, the animals were divided into four groups: Control (three calves from each breed) and Vaccinated (three calves from each breed). The mononuclear cells were obtained from peripheral blood at time zero (before vaccination), one, seven and, thirty days after the vaccination. The cells were submitted to phagocytosis test, NO production and analysis by flow cytometry of the following populations: NK, T, CD4 e CD8 as well as for their IFN-production. The intradermic test was realized in all calves forty-five days after vaccination. Macrophages from Curraleiro breed showed superior phagocytosis rates (7.650±3.661) than Nellore macrophages (2.970±1.282). Before BCG vaccination...

Diferentemente das demais raças, o Bulldog Inglês apresenta um padrão abaulado de conformação do tórax. Essa notória característica associada à predisposição de acentuado acúmulo de tecido adiposo sobre o rebordo costal, dificulta ainda mais o acesso dos principais meios de diagnóstico por imagem ao coração. A tendência racial à obesidade é outro fator limitante, quando se considera a integridade morfofisiológica do aparelho cardiovascular. Cães obesos tendem a ser portadores assintomáticos de cardiopatias ou, em muitos casos, mimetizam sinais clínicos dessas afecções; dificultando a identificação da incidência de distúrbios cardíacos em exemplares dessa raça. Foram utilizados 30 cães adultos, 15 machos e 15 fêmeas, clinicamente saudáveis oriundos do canil MACM Kennels e da casuística das clínicas Bicho de Estimação e CãoQMia, sendo submetidos à avaliações ecodopplercardiográficas, eletrocardiográfica computadorizada, radiográfica e morfométrica. Para todas as variáveis ecocardiográficas e o VHS procedeu-se correlação com o peso corporal e circunferência torácica. Em relação ao sexo, foi utilizado o teste t de Student para comparação dos valores médios, entre machos e fêmeas. As variáveis EFSIV...

In the last years, the interest for the study of the Brazilian fauna s animals has been increasing considerably as a result of the risk of extinction or aiming for the control of the diseases, specially the zoonoses. The Coati (Nasua nasua) is an exclusive species of South America, classified as vulnerable in some states of Brazil. In spite of its large distribution and importance, the data about its ultrasonographic anatomy was not found in the literature. The use of ultrasonographic examination in veterinary medicine is largely disseminated as a way of complementary diagnostic because it offers, as a non-invasive way, information about the organs anatomy and morphophysiology. Although ultrasonography is a largely disseminated complementary diagnostic method in the clinical routine of little animals, there are few accounts in wild animals. The aim of this study was to describe, in a comparative way, the ultrasonographic features and the topography anatomy of coatis liver, kidneys, adrenal glands, ovarian, pancreas, gastrointestinal tract, urinary vesicle, spleen and uterus, and establish reference values to measure the kidneys, urinary vesicle wall and the gastrointestinal tract, contributing in this way with scientific material to the ultrasonography learn in this species. It has been used seven adult and healthy coatis originating from the Wild Animals Selection Center WASC...

Ovariohysterectomy is the most performed surgery in small animals, with the purpose of birth control, avoiding pseudocyesis as also treating female reproductive tract affections. Several surgery techniques have been described. Beyond the traditional midline approach to the abdomen, the flank many laparoscopic approaches may be performed. Twenty-four healthy, mongrel and adult cats took part of the study. They were randomly distributed in four groups of six animals, this way: GI midline approach and ligature with nylon thread; GII midline approach and ligature with nylon clamp; GIII flank approach and ligature with nylon thread and GIV flank approach and ligature with nylon clamp. The times of dieresis, ovariohysterectomy and closure were timed. Clinic evaluations were done at the day of the surgery and at 7 and 28 days after it. Ultrassonographic evaluations were performed at the day of the surgery, before and after it, and at 7 and 28 days after it, to verify possible alterations related to the material used. The results revealed that the midline approach was significantly faster than the flank approach. The ligature time of the pedicles and uterus body, as the total surgery time were statistically shorter for the groups that used the nylon clamp. We also observed a higher incidence of edema in the groups of midline approach at the seventh day after surgery...

The canine gland has drawn interest for research due to its similarities with the human prostate and the great incidence of lesions. Moreover, the canine prostate shows high incidence of diseases. The main lesions that affect the prostate are prostatitis, benign prostatic hyperplasia (BPH), cysts and adenocarcinoma. Recently attention has been given to lesions considered premalignant such as prostatic intraepithelial neoplasia (PIN) and proliferative inflammatory atrophy (PIA), both studied in the human gland and also found in the canine prostate. In order to evaluate the development of prostate cancer starting as premalignant lesions, some immunohistochemical markers are employed, such as tissue inhibitors of metalloproteinases (TIMP), which have a key role in regulating the catalytic action of metalloproteinases (MMP), and transforming growth factor-β (TGF-β), that induces angiogenesis and inhibits cell proliferation and is considered a mediator of prostate growth. The objective of this study was to investigate the expression of TIMP-1, TIMP-2 and TGF-β in canine normal prostate tissue and with proliferative lesions. For this, 150 adult canine prostates were obtained from postmortem examinations. After microscopic evaluation 54 glands...

Radiographic evaluation has been done lately as important diagnosis recourse for bovine locomotor injuries. However the scarcity of study in this area has made difficult the veterinary s performance. The aim of the study was to use radiographic exams to help in the characterization of the most important bone injuries that compromise bovine digit, metacarpophalangeal and metatarsophalangeal joint as well as relate radiographic findings to lameness sings and the presence of feet injuries. Participate in this study fifty male bovines (Zebu x European), confined, carrying locomotor alterations, with or without digital alteration, from the state of Goiás. All the animals were evaluated about the locomotion score the moment they arrived, and 112 days latter at the end of the confinement. After the slaughter, the four member distal extremities were collected (n=200) and evaluated about clinic and radiographic alterations. Claudication was found out in 86% of the animals. The locomotion scores were distributed as fallowing: 14% had score 1, 20% score 2, 52% score 3 and 14% score 4. The comparison between two moments, arrival and end of the confinement, demonstrated the aggravation of the locomotion score during the period the animals were confined. Only 29...

In veterinary medicine, skin injuries represent a significant casuistry and require expensive therapies, considerable recovery time and often lead to unfavorable resolution. To establish an effective therapeutic protocol it is essential that the professional has a solid knowledge of the healing dynamic, as its phases, triggered events, features, as well as about the biological potential of the healing process coadjutants. Regarding these ones, it is known that phytotherapy has a wide range of botanical specimens with healing potential, and, among them, the barbatiman, native species of the Brazilian cerrado, by its antiseptic and astringent activities, becomes an attractive option for skin injures therapies. The chitosan biomaterial also has potential as coadjutant of the process, once it accelerates the triggering of the healing stages by its immunomodulatory property. To clarify the mechanism proposed by these agents, numerous tests are developed using laboratory animals, in order to give reliability to the therapy modality established. To follow clinical evolution in vivo, the clinical examination becomes essential, while morphometric analysis provide accurate data regarding the percentage of centripetal contraction of the lesions. Finally...

The species of Brachiaria are important forages from Brazilian tropical regions, mainly the Central-Western region. Some species of Brachiaria have been described as cause of hepatogenous photosensitization in ruminants. Initially, the disease was attributed to the fungus Pithomyces chartarum, but recent studies suggest that the steroidal saponins present in the grasses have toxic principles responsible for the photosensitization. The objective of this study was to evaluate the hepatic function and the performance of lambs fed with B. brizantha hay or sugar cane (Saccharum officinarum L.), by means of clinical examination, laboratory tests, and macro and microscopic analysis of the liver. Twelve Saint Ines lambs were used. The animals were divided into two experimental groups: group hay (six lambs fed with roughage of B. brizantha hay and concentrate) and group sugar cane (six lambs fed with roughage of sugar cane and concentrate). The hay used to feed the lambs did not contain Pithomyces chartarum spores. The clinical examinations occurred at each seven days, the laboratory tests at each 14 days, and the weighings at each 28 days. At the end of 93 days of experiment the lambs were slaughtered, the macroscopic analysis of the the organs was carried out...

Tramadol is an analgesic with action of opioids and non-opioid receptors, which acts by promoting activation of central inhibitory mechanisms of pain. In the last decade, there was a significant advance in research related to the use of tramadol in horses. There is evidence that the drug has significant analgesic effect in horses through mechanisms unclear. The aim of this study was to evaluate clinical and cardiorrespiratory effects and mechanical nociceptive threshold of tramadol, administered intravenously in horses. Moreover, we assessed also the effects of preemptive administration of tramadol on the clinical effects and post-incisional mechanical hyperalgesia. In the first study, seven adult horses were used in a three-way crossover study design in which tramadol was intravenous administered at 1mg kg-1, 2mg kg-1 e 3mg kg-1. Heart rate, respiratory rate, rectal temperature, systolic arterial pressure, diastolic arterial pressure, mean arterial pressure, intestinal motility, head height and behavioral change were recorded before and during 180 minutes after treatment. Mechanical nociceptive threshold from these points were averaged to obtain mean values at each time with von Frey electronic analgesiometer, applying a force in a hoof.

This study has aimed do evaluate a risk factor for bovine digital dermatitis and the efficacy of 5% aqueous barbatimão extract solution as ancillary in interdigital skin incisional wound repair. One hundred bovine females, 50 Holstein and 50 Girolando, from two different farms were used for the risk factor study. Experimental units were divided into four groups: healthy Holstein cattle group (GHS) and digital dermatitis Holstein cattle group (GHL), healthy Girolando cattle group (GGS) and digital dermatitis Girolando cattle group (GGL). Ten milliliters of blood were collected from all animals and stored in anticoagulant added tubes. Samples were refrigerated and submitted to hemolytic tests for eight bovine blood systems: A, B, C, F, J, L, S and Z. The frequency of blood factors was determined and compared, in each system and each group. Data were analyzed through non parametric tests: Chi Square and Fisher s exact. The results indicated that the blood factors may contribute to the occurrence of digital dermatitis lesions, but further studies are needed for a more accurate conclusion. Thirty confined, 10 months old calves were selected in order to evaluate the efficacy of 5% barbatimão solution. A biopsy punch was introduced in each interdigital space...

The Calendula officinalis L. is an annual herb, originating in the Mediterranean region, belonging to the Asteraceae family and well known as calendula. Displays orange or yellow flowers, which are attributed medicinal properties, with emphasis on healing activity. In this study, the ethanolic extract of flowers of C. officinalis grown in Brazil was prepared by soaking the cold and fractionated to obtain fractions of dichloromethane and hexane. The angiogenesis activity of the extract and fractions was evaluated using the model of membrane corioalantóide in embryonated chicken eggs. But the healing effect of the extract was evaluated by the model of skin wounds in rats, with assessment of macroscopic and microscopic characteristics. In this model, the ethanol extract of angiogenesis activity in the dermis of rats was also evaluated by immunohistochemistry, and measured the intensity of expression of vascular endothelial growth factor (VEGF). The in vitro antibacterial activity of extract and fractions was evaluated by determining the minimum inhibitory concentration (MIC) using the dilution plate. The ethanol extract and the fractions of calendula showed marked angiogenesis activity, demonstrated in both experimental models used. This activity was not related to the observed increase in intensity of expression of VEGF...

Bovine estrous cycle activates the pathways of MAPKs (mitogen activated protein) via oscillation of hypothalamus-pituitary-gonad axis hormones. The objective of this work was to evaluate in vivo the frequency of expression of active (phosphorylated) form, of p-MEK 1/2 and p-ERK1/2 in all types of ovarian follicles and corpora lutea in different phases of the estrous cycle of cattle. Bovine ovaries were harvested in a local slaughterhouse and the phase of the estrous cycle was determined, considering seven stages, defined as experimental groups: days 1-3 (n = 2), 4-6 (n = 5), 7-9 (n = 5), 10-12 (n = 3), 13-15 (n = 5), 16-18 (n = 5) and 19-21 (n = 5). After processing, the histological sections were subjected to immunohistochemistry using antibodies that specifically recognize the phosphorylated form of MEK 1/2 and ERK 1/2. Histological sections containing corpora lutea were also subjected to immunohistochemistry with antibodies that recognize p-BCL2 (B cell phospho lymphoma 2) and COX-2 (COX-2). The frequency of marked follicles was evaluated for the presence or absence of markup for the two cellular enzymes. The fragments of the corpus luteum were evaluated according to the scores of intensity for positive staining of the four antibodies. The frequencies of the markers studied in the follicles were compared using the chi-square. In preantral follicles...

Several aspects of the bovine tuberculosis were analyzed in this study. The immunogenicity of recombinant MPT-51 (rMPT-51), Ag-85 and M. bovis-BCG were characterized in an immunosorbent assay, where 208 serum samples from positive intradermal tuberculin test (ITT) animals and 54 serum samples from ITT negative animals where analyzed. M. bovis-BCG and Ag-85 were strongly recognized by antibodies from naturally infected cattle. Additionally, the clinical status of the animals were correlated with the ITT positivity, with the specific production of IL-4 by TCD4 and TCD8 positive lymphocytes, and with nitric oxide (NO) production by macrophages from naturally tuberculosis infected bovine peripheral blood. ITT positive animals showed TCD4+IL4+ cells specific to M. bovis-BCG extract. High background levels of TCD8+IL-4+ lymphocytes were observed in ITT positive animals independent of the stimuli. When cell cultures where stimulated with M. bovis-BCG protein extract, there was no observed difference in NO production between the groups. Naturally tuberculosis infected bovine presented TCD4+IL4+ cells specific for M. bovis- BCG and a preserved NO production. Finnally, the immunogenicity of rMPT-51 use as a proteic sub-unit vaccine was evaluated in BALB/c mice...

The obesity is a physical condition more frequent in each time in the population of pets, being able to contribute for the sprouting of systemic alterations capable to compromise the health of the animals. Ahead of the displayed one, this experiment was developed in the Veterinarian Hospital of the Federal University of Goiás, with 26 adult female dogs, castrated and without defined brand, they had been fed with commercial diet ad libitum, during 36 weeks, and had biweekly accompaniment of the nutritional state by means of clinical parameters (body condition score - BCS), morphometrics (abdominal perimeter, thoracic perimeter, thigh perimeter) and for the equations for determination of the percentage of corporal fat and index of corporal mass (IMC1=weightkg/height of withersm; IMC2=weightkg/hight of withers2 m; IMC3=weightkg/spine lengthm; IMC4=weightkg/spine length2 m). The metabolic accompaniment was carried through, monthly, by means of evaluation of the serum biochemistry (glucose, urea, creatinin, albumin, triglycerides, total cholesterol and HDL). The objective of the work was to verify the associations between the morphometrics variables and the serum biochemistries, by means of the multivariate analysis of main components. In the results...

The Pantaneiro cattle reveal docility, resistance to illnesses and parasites, and an incredible ability to adapt to Pantanal's edophoclimatic conditions. The cattle may be used without considerable investment to explore low-quality natural pastures in which other breeds might endure low productivity or even survival difficulties. Thus the determination of the normal blood constituents of Pantaneiro bovines was set in order to reveal further information regarding the physiological aspects of these animals. Therefore 293 blood samples were collected from two rural properties, one from Mato Grosso and the other from Mato Grosso do Sul. These individuals were classified in five groups according to their age group, as follows: G1, G2, G3, G4, and G5. The parameters under investigation were the erythrogram and the leukogram. Initially the data was submitted to descriptive statistics which included the determination of averages, standard deviation, and coefficients of variation. Subsequently data was submitted to the Kruskall Wallis test in order to establish the age relationship and to the Mann-Whitney test in order to establish the sex relationship. Age advancement revealed an increase in MCV, MCH, and in the number of eosinophils. Age advancement showed a reduction in the number of red blood cells...
