Avaliação ultrassonográfica dos efeitos da acupuntura na involução uterina em cadelas

The aim of this study was to evaluate, by means of ultrasound exam, acupuncture effects on uterine involution during the postpartum period in bitches with electroacupuncture. The phenomenon of eutocic uterine involution was studied in 16 bitches, randomly divided into two groups of eight animals each. Group 1 (G1) was treated with electric stimulation (electroacupuncture) of the needle at the points SP6, L3, Bai Hui, TB1, B23, B26, and group 2 (G2), the control group, received treatment in Sham points (placebo points), also with electrical stimuli. The monitoring of the phenomenon of uterine involution was performed by ultrasonography on days 0 (partum), 1, 3, 7 and 14 postpartum. We used SAS statistical analysis method, in order to compare the groups. The results of ultrasound examinations (mean and standard deviations in cm) for the period of observation were as follows: G1: 0.30 ± 0.01 (P), 2.08 ± 0.21 (LU), 4.13 ± 0.23 (DU) and G2: 0.31 ± 0.01 (P) 1.82 ± 0.09 (LU), 3.92 ± 0.11 (DU). We concluded that electroacupuncture affected uterine tone (lasting and uniform at the end of treatment). Electroacupuncture produces a positive tone in the uterus, aiding at the prevention of puerperal diseases.

Potencial de produção de gás metano e dióxido de carbono in vitro dos ingredientes utilizados em dietas para ovinos

This study aimed to evaluate the potential of CH4 and CO2 in vitro production of soybean hulls, sunflower meal, corn, citrus pulp and corn silage. Four rumen-cannulated sheep were fed diets containing the evaluated ingredients at 40:60 forage:concentrate ratio. The gases produced by samples incubation were measured by injection into a gas chromatograph equipped with flame ionization detector. The experimental design was completely randomized with repeated measures, with three replicates for each evaluated food at four different periods. Under the experimental conditions, we verified different potential gas production among the ingredients. The citrus pulp meal was the ingredient with the greatest potential for CO2production. Corn silage and soybean hulls showed the greatest potential while citrus pulp and sunflower meal showed the least potential for CH4 production, when expressed in mL/g of degraded dry matter; therefore, they can be considered, among the evaluated ingredients, those with the lowest environmental impact.

Biodegradacao da hepatotoxina(D-Leu1)-microcistina-LR por bactérias presentes em filtros biológicos de carvão

The persistence of MCs in aquatic environments and their difficult removal in the conventional water treatment is a challenge to companies of sanitation. However, the MCs are susceptible to degradation by bacteria present in water, sediment and sewage effluents. In this study, we investigated the biodegradation of MCs by microorganism present in carbon filters with biological activity (BAC) and their phylogenetic identification by sequencing gene 16S RNA. A study of water containing MCs was used, with different compositions, plus a filters BAC effluent. The results showed that of MCs were biodegraded by microorganism present in the biofilm. This study provides the ability to complete biodegradation of MCs by bacteria present in BAC filters and the possible use of these microorganisms as alternative of the removal of MCs in the treatment of drinking water

Influence of glyceryl guaiacolate ether on anesthetics in tilapia compared to benzocaine and eugenol

Objective. The study aimed to investigate the effectiveness of glyceryl guaiacolate ether (GGE) and compare the times of induction, recovery, hematological changes, total protein and glycaemia among anesthetics in Nile tilapia, Oreochromis niloticus. Materials and methods. A total of 60 tilapia distributed in 3 aquariums (N=20) were used, which formed the group benzocaine (100 mg/L), eugenol (50 mg/L) and guaiacol glyceryl ether (9.000 mg/L). After the induction of anesthesia fish blood samples were collected to determine the complete hemogram and glycemia. Then the animals were placed in aquariums with running water for assessing the anesthesia recovery. Results. It was verified that GGE showed longer induction and recovery times as well a significant increase (p<0.05) of glycemia, when compared with the other groups (p<0.05). The concentration of total protein did not differ between groups (p>0.05). An increase in the number of monocytes in the group treated with benzocaine (p<0.05) was observed in the analysis of the hematological parameters with no difference between groups for other variables. Conclusions. Eugenol and benzocaine allow rapid induction and recovery in Nile tilapia, without evidence of stress during handling and GGE showed high induction and recovery times, being inadequate for anesthetic use in Nile tilapia.

Analysis of renal function after on and off pump coronary artery bypass grafting

Cardiopulmonary bypass (CPB) is often associated with renal dysfunction, as measured by plasma creatinine levels and hemodialysis rates. Aim. To compare creatinine clearance (CrCl), estimated with the Cockroft and Gault formula, between patients undergoing off-pump coronary artery bypass grafting (OPCAB) versus on-pump CABG (on-CAB). Material and methods. Between April 2008 and April 2009, 119 patients underwent coronary bypass graft surgery. Fifty-eight (58) of these patients underwent OPCAB while 61 had on-CAB. Creatinine clearance, plasma creatinine levels, and clinical outcome were compared between the groups. A creatinine clearance value of 50 mL/minute was accepted as the lowest limit of normal renal function. Results. There were two hospital deaths caused by sepses after pulmonary infection. Creatinine clearance (Preoperative OPCAB 73,64±33,72 x on-CAB 75,70±34,30mL/min; discharge OPCAB 75,73±35,07 x on-CAB 79,07±34,71 mL/ min; p=0,609), and creatinine levels (Preoperative OPCAB 1,04±0,38 x on-CAB 1,13±0,53 mg/dL; discharge OPCAB 1,12±0,79 x on-CAB 1,04±0,29mg/dL; p=0,407) did not show statistically inter-group differences. Conclusion. Deterioration in renal function is associated with higher rates of postoperative complications. No significant difference in CrCl could be demonstrated between the groups.

Maternal-calf relationships and their influence on calves up to 120 days

Objectives. To research parental behavior and measure the weight of Nelore and Guzerat calves up to 120 days of age, collecting data from birth up to the first lactation. Materials and methods. Seven different corporal positions were considered to obtain specific data for each of the following categories: time to stand (TP), time to intend to feed after standing (TPTM), weight at birth (PN), weight at 120 days (P120), and time in contact with the calf (TCC). Additionally, independent variables were also evaluated, organized by class: weight at birth (CPN), number of calvings (CNP), order of calving in relation with the herd (CLPR), time of calving (CHP), and finally, hindering to feed (CTAT). Results. There was a significant result in favor of the Nelore race over the Guzerat race. The statistical averages for Nelore and Guzerat were: Time to stand averaged 71 and 153 minutes; time to intend to feed after standing, 39 minutes for Nelore and of 114 minutes for Guzerat. For variable weight at 120 days, Nelore reached an average of 122 kg, and Guzerat 109 kg. For the time in contact with the calf variable there was no significant variance between races. Conclusions. Results showed the superiority of the Nelore race, considering it better adapted to local environmental conditions.

Efeitos da infusão contínua de Cetamina s(+) em equinos anestesiados pelo Halotano

The horse’s blood pressure is susceptible to changes induced by volatile anesthetics. Because of that, the use of anesthesic techniques which keep stable the horse´s blood pressure is essencial. Ketamine is an important induction and maintenance anesthetic agent used in the horse anesthesia practice mainly to improve the blood pressure. S(+)-ketamine provides the same effects on the blood pressure, with greater analgesic results and less side effects than the normal ketamine. Although some studies have been conducted with ketamine continuous rate infusion during the halothane anesthetized horses, the S(+)-ketamine has not been evaluated yet. Considering the increased use of ketamine, it is important to evaluate its cardiovascular and respiratory effects in halothane anesthetized horses. To conclude, S(+)-ketamine 0.01mg/kg/min. continuous rate infusion did not induce additive cardiovascular and respiratory depression in halothane anesthetized horses.

Tenotomia do músculo flexor digital superficial e desmotomia acessória em equinos: goniometria radiometacarpiana, metacarpofalângica e interfalângica

The purpose of this study was to investigate the effects of the superficial digital tenotomy and the superior check ligament desmotomy on the radio-metacarpal, metacarpophalangeal, proximal and distal interphalangeal angles in horses. Under general anesthesia the superficial digital flexor tenotomy and superior check ligament desmotomy were performed, respectively, on the right and left forelimbs in nine horses. Before surgery and on 15th, 30th, and 60th postoperative days the radio-metacarpal, metacarpophalangeal, and proximal and distal interphalangeal angles were measured by radiographic examination. Tenotomy decreased significantly the metacarpophalangeal angle (mean ± standard deviation: preoperative – 140.7º ± 6.85; 60th day – 128.2º ± 5.93) and increased the distal interphalangeal angle (mean ± standard deviation: preoperative – 172.6 ± 1.87; 60th day – 167.6 ± 1.36). Desmotomy decreased the proximal interphalangeal angle (mean ± standard deviation: preoperative – 180.2º ± 5.43; 60th day- 197.3º ± 8.29). These surgical procedures did not change the radio-metacarpal angle. The superficial digital flexor tenotomy and the superior check ligament desmotomy cause different and significant changes in joint angles distal to the carpus.

Comparação de métodos para extração de dna na reação em cadeia da polimerase para detecção de Salmonella enterica sorovar enteritidis em produtos avícolas

The identification of Salmonella spp. in food samples by microbiological diagnosis is time consuming, with approximately five different stages, requiring about 120 hours until the final result. The utilization of the polymerase chain reaction technique (PCR) can reduce this time, but substances present in samples may affect the reaction. The present work aimed to compare DNA extraction by thermic treatment and by the use of cetyltrimethil ammonium bromide (CTAB), in products originated from poultry houses corresponding to raw material (meat meal) and experimentally contaminated drag swabs. Materials obtained from the extractions were submitted to PCR, utilizing a pair of initiator oligonucleotides for amplification of Sdf 1 gene fragments. Comparing the methods of extraction, it was observed that when CTAB was employed, SE was detected in 70% of meat meal and in 80% of drag swabs, while the thermic treatment method yielded positive results in 20% of meat meal and in 40% of drag swabs. SE was detected under both methods utilized for DNA extraction, but the use of CTAB detected a greater number of positive samples, compared with thermal treatment.

Glutamina na dieta de poedeiras leves submetidas ao estresse pelo calor e à termoneutralidade

The aim of this study was to evaluate the effect of glutamine supplementation of the diet on intestinal mucosa morphology, performance, and egg quality of commercial laying hens, submitted to heat stress and thermoneutral conditions. In this study, 96 (Isa Babcock) laying hens at 35 weeks of age were used and distributed in a completely randomized design according to a 2x2 factorial arrangement, with two levels of ambient temperature (thermoneutral and hot) and two levels of glutamine in the diet (0.0 and 1.0% of inclusion), in 6 replicates of 4 hens per box. Feed intake, daily egg production, feed conversion per kilogram of eggs, and egg quality were obtained in two periods of 28 days each. Heat stress decreased egg production and quality, and glutamine supplementation improved egg quality and feed conversion. The heat and glutamine supplementation provided an increase in calliciform cells quantity in duodenum and ileum, respectively. Significant morphological modifications in the intestinal mucosa of laying hens were not found.
