Administração de toxina botulínica A e a orquiectomia no tratamento da hiperplasia prostática benigna do cão Ciência Rural
Mostachio,Giuliano Queiroz; Apparício,Maricy; Motheo,Tathiana Ferguson; Alves,Aracélle Elisane; Vicente,Wilter Ricardo Russiano.
A fisiopatologia da hiperplasia prostática benigna (HPB) não está totalmente compreendida, no entanto, a diidrotestosterona é o principal hormônio envolvido. Recentemente, o efeito da toxina botulínica A (TB-A) foi investigado, mostrando que esta induz atrofia do parênquima e redução do volume prostático. Com base nisso, este estudo teve como objetivos comparar os efeitos da administração da TB-A com a orquiectomia no tratamento da HPB, além de avaliar os efeitos da TB-A sobre a libido e qualidade do sêmen. Para tanto, 16 cães adultos foram submetidos à castração ou administração de 500U de TB-A, e avaliados durante 16 semanas. A orquiectomia mostrou-se um excelente tratamento, promovendo redução de 80% do volume prostático. Aplicação da TB-A não ocasionou...

Rodrigues,Paula de Almeida; Coelho,Lia de Alencar; Nonaka,Keico Okino; Sasa,Aya; Vicente,Wilter Ricardo Russiano; Balieiro,Júlio César de Carvalho; Siqueira,Edson Ramos de.
The increased emphasis placed on lamb production in Brazil points to the need for a better knowledge of the annual pattern of reproductive activity in ewe lambs. This study evaluates the annual estrous activity pattern of hair and wool ewe lambs raised in southeast Brazil. Estrous characteristics were recorded for 12 months in ten Santa Inês and 21 Romney Marsh and Suffolk ewe lambs. Santa Inês ewe lambs exhibited a greater length of the normal estrous cycle (14 to 19 days) than Romney Marsh and Suffolk ewe lambs (17.0 ± 0.1 days vs. 16.5 ± 0.2 and 15.9 ± 0.2 days). All the ewe lambs presented a greater number of periods of estrus per animal per month for single estrous cycles (up to 26 days) during autumn and winter. During spring and summer there was a...

Oliveira,Maria Emilia Franco; Cordeiro,Mabel Freitas; Ferreira,Roberta Machado; Souza,Samuel Figueirêdo; Pieroni,Juliana Souza Pinto; Rodrigues,Luiz Fernando de Souza; Fonseca,Jeferson Ferreira da; Vicente,Wilter Ricardo Russiano.
The objective was to evaluate if supplemental LH given at the end of FSH treatment would synchronize the time of ovulation and increase the ovulation rate and embryo yield in Santa Ines ewes. Twenty superovulatory (SOV) programs were accomplished in cross-over design (60d interval). On D0, a CIDR device was inserted, and the device was replaced with a new one 7 days later, when 37.5µg of d-cloprostenol was administered. On D12, we started the SOV treatment, administering 256mg of pFSH 8 times, 12h apart. On D14, the CIDR was removed, and 200IU of eCG and 37.5µg of d-cloprostenol were administered. On D15, the ewes were allocated into one of two groups, a Control group (n=10) that received no supplemental LH and a LH group (n=10) treated with 7.5mg of LH...

Laryngeal and tracheal tumors are rare in pets; some piece of information on their disease behavior, therapy and evolution are limited. Neoplasms in this area are a diagnostic challenge. In many cases, they can be biopsied and excised using endoscopic instruments, but there is no report of this in canines. The goal of this study is to report a successful case of a laryngeal neoplasm removal through endoscopy. A head and neck radiogram revealed a mass in the laryngeal lumen protruding into the trachea. The patient then underwent an endoscopy to confirm the radiographic diagnosis and to surgically remove the tumor. The histopathological diagnosis was poorly differentiated carcinoma. The most appropriate treatment for laryngeal tumors is the resection of the...

Estudo da papila mamária em fêmeas bovinas (Bos taurus - Linnaeus, 1758), mediante as características ultra-sonográficas em modo-B (tempo real) Braz. J. Vet. Res. Anim. Sci.
Santos,Diogo Antonio da Silva; Vicente,Wilter Ricardo Russiano; Canola,Julio Carlos; Léga,Euzylene.
Nesta pesquisa foram utilizadas vinte fêmeas bovinas, sem patologias aparentes nas glândulas mamárias, em lactação, objetivando avaliar estruturas anatômicas das papilas mamárias. Quatro técnicas ultra-sonográficas foram avaliadas. Utilizou-se transdutor linear de 7,5 MHz para uso endoretal, na obtenção das imagens, padronizando-se o lado direito do animal para visualização das papilas craniais e caudais, em dois planos anatômicos (sagital e transversal). Os animais foram divididos em quatro grupos (G1, G2, G3, G4) que representaram as diferentes técnicas empregadas em momentos distintos (antes e após ordenha). Os resultados indicaram que entre as técnicas estudadas, as de exame direto e com uso de almofadada de silicone, foram as que apresentaram maior...

Hemodynamic gestational adaptation in bitches Ciência Rural
Almeida,Vívian Tavares de; Uscategui,Ricardo Andres Ramirez; Silva,Priscila Del Aguila da; Avante,Michele Lopes; Simões,Ana Paula Rodrigues; Vicente,Wilter Ricardo Russiano.
ABSTRACT: Throughout pregnancy, maternal hemodynamic adaptation is needed to ensure proper uterine perfusion and fetal development. When the uteroplacental vascular system is formed, starting with reduced resistance to uterine arterial flow, this results in decreased total vascular resistance, an activation of neuroendocrine vasoactive peptides, an increase in circulating blood and changes in the cardiovascular system morphophysiology to respond to the increasing demands of uterine perfusion. There has been considerable study of hemodynamic adaptation in pregnant women and this assessment has become a diagnostic tool for fatal obstetric disorders. However, in bitches the available information in this regard is limited; therefore a parallel was drawn...

Motheo,Tathiana Ferguson; Alves,Aracélle Elisane; Mostachio,Giuliano Queiroz; Apparício,Maricy; Ribeiro,Alexandre Pinto; Souza,Fabiana Ferreira de; Lopes,Maria Denise; Vicente,Wilter Ricardo Russiano.
This study aimed to determine the effects of different concentrations of botulinum toxin type A (BT-A) on semen parameters, and seminal plasma biochemical and protein profiles of dogs with benign prostatic hyperplasia (BPH). Eighteen sexually intact male dogs with BPH were randomly divided in three groups, and received an intraprostatic injection of saline solution (control group - CG), 250UI (GI) or 500UI (GII) of BT-A under transabdominal ultrasound guidance. Semen was collected at baseline, 2, 4 and 8 weeks after treatment. Semen parameters were determined and seminal plasma pH, total protein (TP), total chlorides (TC), calcium (Ca), potassium (K), and sodium (Na) concentrations were assessed. One-dimensional sodium dodecyl sulfatepolyacrilamide gel...

Single incision laparoscopic surgery (SILSTM) using an umbilical hernial approach for cryptorchidectomy of a degenerated testis in a dog Ciência Rural
Tiosso,Caio de Faria; Voorwald,Fabiana Azevedo; Brun,Maurício Veloso; Nakaghi,Luciana Cristina Padilha; Crivelaro,Roberta Martins; Apparicio,Maricy; Vicente,Wilter Ricardo Russiano.
ABSTRACT: SILSTM via an umbilical hernia opening was used in the correction of an abdominal cryptorchidism in a dog. The SILSTMport was inserted through a 2.5 cm skin incision on the umbilical hernia and pneumoperitoneum was established with CO2. A 10mm telescope, 5mm laparoscopic Babcock clamp, and a clamp with combined cutting and coagulation features were used for the dissection and removal of the testicle through the SILSTM port. The treatment proved to be effective, easy, and quick to perform. However, the lack of triangulation between clamps and telescope limited the movement of the instruments, making it more laborious than a multiple-trocar approach. It can be concluded that the use of a SILSTM port through a pre-existing opening of the abdominal...

ABSTRACT: The aim of the study was to develop and assess the feasibility, postoperative pain and inflammatory response of the single-port laparoscopic ovariectomy in ewes, using a simple pre-tied loop ligature technique. Pre-tied Meltzer's knot was employed for prophylactic hemostasis of the ovarian pedicle. Slipknot was inserted within the abdominal cavity through a 14-gauge needle and tied surrounding the ovarian pedicle. Mean surgical time, manipulation, ligature and resection of each ovary and anesthesia time were 63±20, 20±10 and 91±26 minutes, respectively. No bleeding occurred during the surgeries. Ewes showed low scores pain (0.5±0.5) at all time-points. Postsurgical plasma fibrinogen was within the normal range for sheep specie at all time-points....
