title: Benefits of chondroitinase abc associated with mesenchymal stem cells in acute spinal cord injury in rats

description: ABSTRACT The aim of this work was to study the effect of chondroitinase associated with mesenchymal stem cells in acute spinal cord injury. Therefore, 50 Lewis rats were distributed in the following groups: negative control (NC), treatment with placebo (PLA), chondroitinase (CDT), mesenchymal stem cells (MSC), and chondroitinase associated with mesenchymal stem cells (CDT + MSC). All animals had their spinal cord exposed by laminectomy, and the groups named PLA, CDT, MSC and CDT + MSC also suffered compressive spinal cord trauma. After seven days, the spinal cord was re-exposed, when the PLA and MSCs groups received 4uL of artificial cerebrospinal fluid through the lesion, and the CDT group and CDT + MSC received the same fluid containing 2,2U of chondroitinase. 14 days after the first surgery, all animals received 0.2ml of PBS intravenously; however, the MSC and CDT + MSC groups received the same liquid also containing 1x106 MSCs. The motor skills were evaluated up to 28 days post-injury and, subsequently, the spinal cords were analyzed by RT-PCR for BDNF, NT-3, VEGF, PECAM-1 and KDR gene expression quantification, immunohistochemistry to detect injected stem cells GFP (anti-GFP), to quantify neurons (anti-NeuN), GFAP and detect vimentin in order to evaluate the glial scar. Statistical analyzes were performed by Prism 5 for Windows using a 5% level of significance. There was no difference between groups with regarding motor capacity. The CDT + MSC group showed increased immunoreactivity of viable neurons than placebo. In MSC, there was a greater expression of neurotrophic factors BDNF and VEGF. Also, there was less vimentin immunostaining in group CDT. It was concluded that CDT + MSC association promotes neuronal viability after trauma, in which treatment with MSC promotes increased expression of BDNF and VEGF trophic factors, and also that treatment with chondroitinase is effective in reducing the glial scar.

title: Crude protein requeriment to curimatã-pacu juveniles

description: ABSTRACT The aim of this study was to determinate crude protein (CP) requirement to curimatã-pacu juveniles (Prochilodus argenteus). The experiment was conducted during 60 days in a completely randomized design, with four treatments (24.0, 28.0, 32.0 and 36.0% CP of diet) and five replications, where a hundred juvenile fishes (initial weight de 0.33 ± 0.01g), were distributed in twenty tanks (130L each). Each tank with five juveniles was considered an experimental unit, with water recirculation. Performance, heterogeneous growth, morphometric and physiological parameters, and economic viability of the rations according to the CP levels were evaluated. For the regression analysis, a linear increase in performance, heterogeneous growth and morphometric and physiological parameters with increased of the protein in rations were observed. When compared by the Tukey test (P&gt;0.05), the best results were obtained with 36% CP. There was lower fish growth heterogeneity as the levels of CP in the diet increased. Thus, taking into consideration the economic viability it is recommended to use feed containing 36% of crude protein to curimatã-pacu juveniles.

title: Seroprevalence of Visna-Maedi Virus (VMV) and Border Disease Virus (BDV) in Van province and around

description: ABSTRACT The present study investigated the seroprevalance of Visna Maedi Virus (VMV) and Border Disease Virus (BDV) infections in sheeps in regions in and around Van province, Turkey. Sample materials were taken from 360 sheep sent to slaughterhouses around Van. All serum samples were examined using ELISA for antibodies for Visna Maedi (VMV) and Border Disease (BDV) viruses. Of these, 38 (10.5%) tested positive for Visna Maedi virus antibodies and 163 (45.2%) for Border Disease virus antibodies. Varying numbers of samples were positive for both virus antibodies across the towns of Erciş, Çaldıran, Erçek and Başkale in Van, Ağrı and Hakkari provinces. Both infections should be eliminated by informing veterinarians and animal owners, identifying and eliminating persistently infected animals from flocks, and conducting appropriate eradication measures. Economic support should be provided for this.

title: Effect of different intensities of treadmill exercise on eletrocardiographic parameters of healthy dogs

description: ABSTRACT This study aimed to stardardize high and low intensity exercise tests, and evaluate the electrocardiogram of dogs submitted to these tests. Seven clinically healthy Australian Cattle dogs and four Border Collies underwent two exercise treadmill tests, with at least a seven day interval: T1 - high intensity and short duration exercise test, and T2 - low intensity and long duration exercise test. Amplitude and duration of waves and intervals were assessed at resting time before exercise (M0), at immediately after (MPE) and at 30 minutes (M30) after the end of the tests. Heart rate and cardiac rhythm were evaluated before the tests and continuously for 30 minutes after the end of exercise. There was a significant difference only for duration of the QT interval at M30 in T1, and some arrhythmias such as isolated atrial and ventricular premature complexes in three animals after T1 test, and in four dogs after T2. The exercise tests of the present study was suitable to promote sympathetic stimulation in dogs, however did not cause significant changes on the electrocardiogram probably because of the excellent physical fitness of the dogs.

title: Relationship between clinical symptomatology on the isolation of Salmonella Gallinarum of japanese quail (Coturnix coturnix)

description: ABSTRACT Salmonella Gallinarum is capable of causing high mortality in birds of the order Galliformes. This study aimed to relate the presence of clinical signs with the recovery of Salmonella Gallinarum from organs and c loacal swabs of Japanese quails (Coturnix coturnix) experimentally infected. A total of 70 female quails were housed in a pair per cage and divided in two groups (IG: quails inoculated with 1.5x106 CFU of Salmonella Gallinarum Nalr/mL and CG: control group). After the inoculation, birds were evaluated three times a day to verify the presence of clinical signs. Birds that presented ruffled feathers, eyes closed and remained quiet in the cage were removed for euthanasia, as well as the same number of birds from the inoculated groups that presented no clinical signs and from the control group. Cloacal swabbing was performed following euthanasia for the sampling of liver, spleen, caeca, ovarian follicles and lung for microbiological procedure. Quails with clinical signs and quails found dead presented positivity of 100%. While inoculated quails with no clinical signs presented a lower positivity (38.5%). Therefore, quails with septicemia caused by SG present clinical signs of the disease and the pathogen can be isolated and quantified in the organs.

title: Impact of uveitis score on different types of corneal ulcers in dogs subjected to the bulbar conjunctival pedicle graft - 34 cases

description: ABSTRACT The present study aimed to evaluate the results of 34 eyes of dogs presenting deep corneal ulcer (n=5), colagenolytic corneal ulcer (n=2), descemetocele (n=7), corneal perforation (n=15), and iris prolapse (n=5) that were corrected by the bulbar conjuntival pedicle graft (CPG). The uveitis score and the corneal integrity were correlated with the presence or absence of vision by contingency tables. Brachycephalic breeds accounted for 91.11% of all cases. The number of perforated corneas [20/34 (58.82%)] were higher than the non-perforated ones [14/34 (41.17%)]. At post-operative day 50, the number of visual eyes with non-perforated corneas before surgery (n=13) did not differ significantly from the eyes with perforated corneas (n=12) (P = 0.05). In half of the cases, uveitis score was considered severe [17/34 (50%)], and in the other half, mild. Eight out of 17 eyes classified with severe uveitis regained vision. In 17 eyes where uveitis score was considered mild, 16 regained vision at the end of the study. Although corneal integrity was non-correlated with the uveitis score (P = 0.48), the number of visual eyes scored with mild uveitis were significantly larger than the eyes with severe uveitis (P = 0.006). In this study, the overall success visual rate after CPG was 73,52% % and the corneal integrity did not play an important role regarding maintenance of vision. However, eyes presenting severe uveitis score had less chance to regain vision.

title: The low marandu palisadegrass at the beginning of stockpiling improves pasture morphology and increases sheep performance in winter

description: ABSTRACT The objective of this study was to evaluate the effects of four heights (15, 25, 35, and 45cm) of Urochloa brizantha cv. Marandu (marandu palisadegrass) at the beginning of the deferment period on the pasture morphology, selectivity, and performance of sheep during the beginning, middle and end of the grazing period in winter. A completely randomized design with three replications was used. Deferred pastures with 35 and 45cm presented larger forage masses than those deferred with 15 and 25cm. Deferred pasture with 15cm presented a higher percentage of live leaf and a lower percentage of dead stem. Dead leaf selection increased during the grazing period. In general, in the higher deferred pastures, the percentages of live leaf were lower and those of dead stalk, higher in the samples of simulated grazing. The sheep performance was higher in the 15cm pasture, intermediate in the 25 and 35cm pastures, and inferior in the 45cm pasture. The maintenance of marandu palisadegrass with 15cm at the beginning of the deferment period results in deferred pasture with better morphology, optimizes the selectivity and the increase the performance of the sheep in the pasture deferred during the winter.

title: Water management applied to the processing of Atlantic Salmon (Salmo salar) and Dolphinfish (Coryphaena hippurus) in a fish cold storage warehouse in Rio de Janeiro, Brazil

description: ABSTRACT The high consumption of water and uncontrolled wastewater generation commonly seen in fish processing plants are a matter of concern. Sustainable actions must be taken to addres this issue. The present study aimed to quantify the water used in the processing of Atlantic Salmon (Salmo salar) and Dolphinfish (Coryphaena hippurus) in a fish warehouse in Rio de Janeiro, Brazil, through water balance and mass balance at each development stage. According to the data obtained, the warehouse showed higher total water use, both in general (7,173.28±265.77m3/month), with most water use intended for processing support activities, approximately 45.00% (3,186.82±407.57m3/month); specifically, in the processing of the selected raw materials, with greater consumption of water for obtaining one kg of Dolphinfish fillets and slices, around 4.80 x 103m3/kg in both. This suggests the use of sustainable methodologies that result in decreased water consumption and in reuse of solid waste, since the three processing stages studied generated a high amount of solid waste, with emphasis to filleting in both species, with 55.00% of residual production each. The present study will also serve as the basis to other studies on the same issue in the fishing area.
