title: Eletrocardiographic monitoring in the development of Wistar Rats

description: ABSTRACT The cardiac electrical activity can be recorded through the electrocardiogram (ECG), this recording is able to capture the changes in the electric route. In the scientific literature, there is no description of electrocardiographic patterns of Wistar rats at the stage of newborn to be considered aged. The aim of this study was to evaluate the electrocardiographic pattern of Wistar rats at various stages of growth, in order for the results to contribute as a standard reference. Rattus norvegicus albinus rats of the Wistar lineage were used. The rats were divided into 5 experimental groups being defined according to age and named as follows: group 21 days (21D), 2 months (2M), 3 months (3M), 7 months (7M) and 18 months (18M), where n = 20 per group. For the realization of ECG, electrodes connected to the electrocardiograph channels were positioned in animals to capture the electrical signal of the heart in 6-lead. The data were grouped and subjected to comparison by ANOVA and Tukey-Kramer test, P=0.05. The results showed that, overall, the modulations along the front aging process, related to the ECG, are initiated from 2M period, apparent stability by 3M and/or 7M, followed by exacerbation of modulations in 7M and/or 18M, depending on the electrocardiographic variable in question. Front of heart rate (HR), concomitantly, there is a similar pattern, that is, decreasing from 2M period with stability until 7M, followed by more pronounced decrease in 18M. The results suggest that due to the aging process, the heart of Wistar rats shows changes in the conduction of electrical stimulation and reduction in heart rate, factors that deserve attention as indicators of inclusion / exclusion of animals in experimental groups by researchers using that species as a model.

title: Biochemical composition of the hoof capsule of buffaloes and its influence on hoof quality

description: ABSTRACT The purpose of this study was to establish the biochemical parameters of the abaxial wall, dorsal wall and sole of the hoof of the medial thoracic, lateral, and medial pelvic digits of buffalos. The hoof samples were subjected to destructive biochemical analyses to identify the dry material (DM), mineral matter (MM), organic matter (OM), crude protein (CP) and ether extract (EE) contents. Sulfur (S), calcium (Ca), potassium (K), phosphorus (P), zinc (Zn) and copper (Cu) levels were determined based on nondestructive biochemical analyses. The parameters of dry material, mineral matter, organic matter, crude protein and ether extract of hoof capsule of the digits of buffalos can be determined by means of both destructive and nondestructive biochemical analysis. In addition, this study revealed that the highest concentrations of DM, CP and minerals such as, K, Zn and Cu are concentrated in the digits that bear the greatest body mass weight, suggesting that there is a positive correlation between the aforementioned parameters and the strength and growth of the hoof capsule in the digits. As for the element S, this study demonstrated that its highest concentration is located in the lateral digits of the pelvic members.

title: Treatment of a canine high grade lingual mast cell tumor with radiation therapy and chemotherapy: case report

description: ABSTRACT An 8 year old female boxer was presented with salivation, halitosis and dysphagia. In the clinical examination, an ulcerated mass in the middle third of the tongue was observed, measuring 3.5 x 4.0cm. Histopathology and immunohistochemistry the confirmed diagnosis of a high-grade mast cell tumor. Surgical treatment (partial glossectomy) was declined by owner, and radiotherapy was indicated. The protocol consisted of fifteen daily fractions of 300 cGy each. The equipment used was an orthovoltage unit. The tumor had complete clinical remission after the fourth session, and mild mucositis was the only side effect observed. Systemic chemotherapy was performed with vinblastine and lomustine, alternated every 14 days, during four months. There is no evidence of local recurrence or metastasis in this patient twenty-two months after treatment. The combination of radiation therapy and chemotherapy can be considered as an alternative therapy in cases of unresectable mast cell tumors. It led to complete and durable remission of an aggressive tumor, with great quality of life.

title: Aneurysmal bone cyst in soft tissue in a dog - Case Report

description: ABSTRACT This paper describes the diagnosis and treatment of a dog with a rare aneurysmal bone cyst in soft tissue. The patient was attended in the Veterinary Clinic Hospital at the Fedral University of Rio Grande do Sul due to limited mobility, weakness in hind limbs, and dyschezia for 15 days. It was already receiving medical treatment without success. Upon clinical examination a solid increase volume in the right perineal region was detected, and complementary imaging tests were requested. Radiography of the region suggested right perineal hernia or neoplasia. The dog was submitted to surgery, and a rounded and ossified tumoral structure was removed. The histopathological exam diagnosed the structure as an aneurysmal bone cyst in soft tissue, and the patient recovered fully after surgical excision.

title: Evaluation of intranasal oxygen supplementation in mules anesthetized with the combination of ketamine, butorphanol, and guaifenesin

description: ABSTRACT Hypoxemia is a major complication of field anesthesia and no studies regarding this occurrence in mules has been done. Thus, the aim of this study was to evaluate intranasal oxygen supplementation (IOS) in mules (Equus caballus x Equus asinus) anesthetized with ketamine/butorphanol/guaifenesin combination. For this, we used six male, adult mules (322±29kg) which underwent premedication (MPA) with 0.2mg/kg of midazolam intramuscularly after 15 minutes, 0.02mg/kg detomidine IV 5 minutes after, induction IV with combination of ketamine (2mg/mL), butorphanol (22.5mg/mL), and guaifenesin (50mg/mL) (K/B/G) until lateral decumbency. Maintenance was done with the same anesthetic combination. The animals were submitted twice to the protocol described above, 20 days apart, forming two groups. CG: MPA, induction (0.92±0.24mL/kg (mean±SD)), and maintenance (2.2±0.2mL/kg/h) without SIO; TG: MPA, induction (0.98±0.17mL/kg), and maintenance (2.3±0.4mL/kg/h) with IOS flow 40mL/kg/h. During anesthesia arterial blood was collected every 20 minutes (T0, T20, T40, and T60) for blood gas analysis. Data analyzed by ANOVA followed by the Bonferroni test. P&lt;0.05 was considered significant. Hypoxemia of the animals in the CG in periods (59±5; 55±5; 53±7; 49±8) with lower averages than the TG (160±4, 115±34, 92±25, 81±19) was observed, demonstrating that IOS increases PaO2 avoiding the occurrence of hypoxemia.

title: Influence of orchiectomy of seven month old bulls on bronchoalveolar immune function

description: ABSTRACT The present study evaluated the impact that orchiectomy, a routine but painful intervention in bovine husbandry, can cause on pulmonary immunity. To identify whether orchiectomy can impair lung defense, analyses of serum cortisol concentration and of alveolar macrophage and their function (phagocytosis and respiratory burst) were evaluated. Sixteen Holstein bulls (7 mo old, 250±50kg of body weight BW) were divided in two homogeneous groups - the castrated group and the sham group - and the sample were collected on Days -7, 1 and 7 relative to the day of the procedure. Serum cortisol concentration statistically increased on Days 1 and 7 (D-7: 4,97±1,28ng/ml; D1: 6,35 ±1,10ng/ml; D7: 8,28±1,94ng/ml) after castration and these variables seem to impact the alveolar macrophage percentage on D1 (D-7: 76,86±3,44%; D1: 60,92±2,44%; D7: 74,17±2,56%) and their respective function of phagocytosis (P) and the oxidative burst (OB) on Days 1 and 7 for the castrated group (P D-7: 56,25±15,63 arbitrary values; D1: 54,75±14,07 arbitrary values; D7: 31,77±8,44 arbitrary values; and OB D-7: 222,34±39,52 arbitrary values; D1: 135,25±37,68 arbitrary values; D7: 117,73±18,17 arbitrary values). These results indicate that surgical castration affected lung defense until seven days after the practice, so the pulmonary cell function was impaired for a period higher than that reported in the literature.

title: Combined of butaphosphan and cyanocobalamin on the glucose metabolism of dairy cows after calving

description: ABSTRACT The hypothesis of this study is that the combined use of butaphosphan and cyanocobalamin could enhance peripheral insulin resistance, increasing the amount of glucose available for the mammary gland and milk production. Thus, our aim was to investigate the combined effects of butaphosphan and cyanocobalamin on the glucose metabolism in dairy cows during the postpartum period. Twenty one dairy cows were divided into two groups: Control Group (CON, n= 11), that received 5 injections of saline solution (20mL/animal 0.9 % NaCl), and Catosal group (ABC, n= 10) which received 5 injections of 20mL of a Butafosfan and Cyanocobalamin solution (Catosal(r) B12, 100mg of Butafosfan and 50µg Cyanocobalamin for mL). The injections were performed by intramuscular route, on days 7, 12, 17, 22 and 27 postpartum. Blood samples were taken on these days to evaluate plasma concentrations of phosphorus, glucose, non-esterified fatty acids (NEFA), albumin, aspartate aminotransferase (AST) and creatine kinase (CK). On days 8 and 28 postpartum, the animals were weighted and subjected to the glucose tolerance and insulin challenge tests. The treatment promoted weight loss (ABC 40.4kg, CON 10.73kg, P&lt; 0.05) and increased AST (ABC 62.92 ±3.31U/L, CON 53.11 ±3.49U/L, P&lt; 0.05) and CK levels (ABC 134.09 ±19.08U/L, CON 79.43 ±18.27U/L). Glucose metabolism (area under the curve) did not differ (P&gt; 0.05) among groups on days 8 and 28; however, ABC animals showed higher serum glucose levels (P&lt; 0.05) after insulin administration on day 28 postpartum (97.54 ±8.54mg/dL) when compared to day 8 (83.01 ±8.54mg/dL). It could be concluded that the combined use of butaphosphan and cyanocobalamin interferes positively with the adaptation of glucose metabolism in dairy cows in early lactation.

title: Exercise training of dogs with myxomatous valve disease

description: ABSTRACT The present study has the objective of evaluating the effects of exercise training, using moderate intensity walking (60 to 80% of maximum heart rate), from 30 to 50 minutes, three times a week, in alternate days, during eight weeks, on heart rate variability in dogs with myxomatous valve disease (MVD). For that, 20 dogs in stages B1 (1), B2 (14) and C2 (5) of MVD (ACVIM classification) were divided into untrained control group (CG, n=9) and training group (TG, n=11), and assessed at baseline (T0), after four (T1) and eight weeks (T2). Only one B1 and five B2 dogs completed the training program. In the time domain, the rMSSD was greater in TG in T1 (155,5+42,07) and T2 (199,8+83,54) than CG (T1:91,17+35,79 and T2:88,17+57,51). In the frequency domain, the variable High Frequency (HF) increased in TG in T1 (30950+25810) and T2 (40300+33870) when compared to the CG (T1:19090+23210 and T2:18810+22200) and within the group TG in T2 in relation to T0 (29340+20950). The proposed walking protocol is concluded to have increased the rMSSD and HF variables in TG, representing an increase of the parasympathetic tonus, justifying the indication of this therapy in B1 and B2 stages of MVD.

title: Serum levels of proteins and acute-phase proteins in captive emus ( Dromaius novaehllandieae ) of different ages

description: ABSTRACT Protein electrophoresis is a relatively simple technique that allows separating serum protein fractions, and provides important information in the investigation and diagnosis of several diseases. This study determined the levels of acute-phase proteins in the serum of healthy, captive emus (Dromaius novaehollandiae). Animals were divided into two groups (n=11 in each) based on age, with 1-year-old and 4-year-old emus. Acute-phase proteins were separated by SDS-PAGE. Ceruloplasmin, transferrin, albumin, haptoglobin, acidic glycoprotein, IgA, and IgG were detected in the serum of all animals. Protein profiles varied significantly with age (P&lt;0.05). Individuals in the 4-year-old emus group had higher values of ceruloplasmin, transferrin, albumin, haptoglobin, and acidic glycoprotein, compared with the group with 1-year-old animals, showing the role of age in the protein profile of this species. Reference values for acute-phase proteins in healthy emus may be useful in the evaluation of health status and in the diagnosis of diseases affecting the species.
