All animals underwent daily vaginal cytological examination to identify the current cycle phase. For each phase of the estrous cycle, ultrasound examinations were carried out to identify and describe the morphology of both ovaries. Topographic parameters in an ultrasound window were established to locate the ovaries. The agouti estrous cycle lasted an average of 29.94 ± 6.77 days. During vaginal cytology examinations, all cell types were identified, and each phase of the estrous cycle was established by cell counts. No significant alterations were observed in the assessed ovarian morphometry measurements. In 75% of the animals examined, ovarian follicle presence was observed in the proestrus phase.

Essa espécie de sagui é muito comum e de fácil adaptação ao cativeiro, aspecto que estimula a captura clandestina desses animais, os quais são vítimas de maus tratos que causam lesões. A falta de conhecimento da anatomia de saguis e outros animais silvestres dificulta a aplicação segura de procedimentos clínicos, cirúrgicos e terapêuticos. O plexo braquial tem sido descrito em algumas espécies animais, porém até o momento não existia descrição em saguis-de-tufos-brancos (Callithrix jacchus). Para estudar o plexo branquial desses animais foram dissecados dez cadáveres de saguis-de-tufos-brancos (Callithrix jacchus) adultos sendo cinco machos e cinco fêmeas. Em todos os animais o plexo braquial originou- se dos nervos espinhais C5, C6, C7, C8 e T1, com poucas variações na origem e nas contribuições dos nervos, em ambos os ant...

Visando solucionar o ponto onde os fascículos do plexo braquial podem ser localizados no interior da fossa, propusemos medidas a partir da face anterior da clavícula e do ângulo formado pelo encontro do músculo deltóide com a clavícula (ângulo deltoclavicular). A primeira medida permite localizar em profundidade o local onde passa o plexo braquial. Já a segunda, determina a projeção dos fascículos dentro da fossa, o que corresponde ao ponto de entrada da agulha na superfície cutânea. Método-Foram efetuadas medidas entre a face anterior da clavícula e os fascículos do plexo braquial, e do ângulo deltoclavicular até a projeção superficial dos fascículos. Com base nos achados anatômicos foi proposta uma técnica de abordagem do plexo braquial por via infraclavicular. Resultados-Foram analisadas 100 regiões infraclaviculares de cadáveres fixados. A fossa infraclavicular foi detectada em 96 casos. Nessas os fascículos do plexo braquial localiza-se totalmente ou parcialmente em 97,9%. A medida aferida entre a face anterior da clavícula e os fascículos do plexo, foi de 2,49 cm e do ângulo deltoclavicular até a projeção superficial dos fascículos estava em 2,21 cm. Conclusões-Os dados obtidos permitem a determinação precisa do ponto de introdução da agulha, a qual, dirigida perpendicular à pele, atinge o plexo braquial sem perigo de provocar pneumotórax ou lesão vascular, possibilitando uma segurança maior aos anestesiologistas, e permitindo a volta da prática do bloqueio do plexo abaixo da clavícula. UNITERMOS-ANATOMIA: plexo braquial; TÉCNICAS ANESTÉSICAS, Regional: bloqueio do plexo braquial SUMMARY Gusmão LCB, Lima JSB, Prates JC-Anatomical Basis for Infraclavicular Brachial Plexus Block Background and Objectives-This study shows the constant infraclavicular fossa presence, aiming at using it as a pathway for infraclavicular brachial plexus block. Determining the point where brachial plexus fascicles may be located within the fossa, the authors have proposed measurements from the anterior surface of the clavicle and the angle formed by the deltoid muscle and the clavicle (deltoclavicular angle). The first measurement allows the in-depth location of the site crossed by the brachial plexus. The second determines fascicles projection within the fossa, corresponding to the needle insertion point on the skin. Methods-Measurements were made between the anterior surface of the clavicle and brachial plexus fascicles, and from the deltoclavicular angle to superficial fascicles projection. Based on the anatomic findings a technique of infraclavicular brachial plexus approach was proposed. Results-A hundred infraclavicular regions in cadavers were analyzed. Infraclavicular fossa was detected in 96 cases where brachial plexus fascicles were totally or partially (97.9%) located. The distance between the anterior surface of the clavicle and brachial plexus fascicles was in average of 2.49 cm and from the deltoclavicular angle to superficial fascicles projection was 2.21 cm. Conclusions-Values obtained allow for the precise location of the needle insertion point which, when perpendicular to the skin, reaches brachial plexus without danger of causing pneumothorax or vascular injury, providing more safety to anesthesiologists and allowing the return to the practice of brachial plexus block below the clavicle.

The conditions that the animals are put through by the traffic greatly deteriorate their health, as they are kept in tight places, without ventilation and without access to water or food until they reach their final destination. During this process, many of the animals die and others, when

However, little is known about their physiological blood markers, which are crucial for animal husbandry and effective welfare management. This study provides hemogasometric and ionic venous parameters for female agoutis raised in captivity in the drylands of Brazil. Venous blood samples were collected from six females and analyzed for dissolved gases and ions in the blood. Hemogasometric parameters, especially base excess and anion gap were generally heterogenous, while ions varied little among individuals. Moreover, we observed high chlorine values and negative base excess values, which suggest that some animals might be implementing compensatory mechanisms for ion imbalances. We provide a preliminary note on agouti venous gases and ions, while reiteratin...

The present report intends to demonstrate the applicability of the slicing technique in the recovery of postmortem oocytes in a small leopard (Leopardus tigrinus), a victim of trampling, observing the amount of oocytes and their respective morphological degrees for possible cell maturation. A total of 88 oocytes were collected and classified into three grades according to their conformation. The ovarian cutting technique was feasible for the recovery of oocytes in the species and presented a considerable number of ovarian collection in excellent condition, however, it is suggested to carry out additional studies to obtain complementary data.

Methods: Were used eight animals, which were sedated, anesthetized, kept under hypnosis, and submitted to plexus block using a neurolocalizer. The physiological parameters, the nociception and response threshold (mA), were evaluated before and after the block. The response to electrical stimulation and cutaneous sensitivity were evaluated. The groups were compared by the Tukey or Friedman test at 5%. Results: The technique promoted blockage of the plexus, and movement of the thoracic limb in response to electrical stimulation decreased after 10 minutes. The applied milliampere increased after 5 minutes. The cutaneous sensitivity reflex decreased. The average time of return of spontaneous limb movement exceeded 50 minutes. Conclusions: The use of 5mg/kg of lidocaine 2% promoted loss of cutaneous sensitivity and limb muscle relaxation during the evaluation period.

The present work aimed to conduct a cross-sectional survey for leptospirosis in the canine population of the Brejo Paraibano microregion, semiarid of Northeastern Brazil. From May to October 2017, blood samples from 414 dogs were collected in the counties of Alagoa Grande (n=100), Areia (n=79), Bananeiras (n=72), Alagoa Nova (n=73), Serrraria (n=25), Pilões (n=25), Borborema (n=20) and Matinhas (n=20). The tutors of the sampled dogs answered an epidemiological questionnaire, obtaining information about the animals, owner, residence and breeding of the dogs. Subsequently, the serum samples were subjected to the microscopic agglutination test (MAT), using a collection of 23 serovar pathogenic antigens and using the 1:50 dilution as the cutoff point. Of the 414 dogs analyzed 52 were seroreactive, resulting in an apparent prevalence of 12.6% and a real p...

The aim of the present study was to establish the craniometric data and describe the main skull bones and structures of Amazona aestiva, which has become common in veterinary clinics, originated from the legalized purchase or trafficking of animals. A total of 20 adult specimens were used, donated for studies by the Paraíba Wild Animal Screening Center (Centro de Triagem de Animais Silvestres da Paraíba (CETAS-PB)/IBAMA-PB, Brazil. The skulls were dissected and macerated with water. First were identified the frontal, maxilla, mandible, nasal, jugal and quadrate bones that served as a base to identify other bone structures that were then compared with the skull of other bird species already described in the literature, especially psitacids. Values were obtained by measuring with a digital pachymeter, and the maximum skull length was 63.0 mm, the max...
