CMT was performed during ante-mortem inspection; post slaughter, breast tissue and nipple skin samples were collected from 332 bovine quarters. Samples were fixed in 10% buffered formalin and processed by inclusion in paraffin and hematoxylin and eosin staining.

This study aimed to compare two multimodal injectable anesthesia protocols and to determine the appropriate protocol to perform a medial laparotomy and embryo recovery in sheep. 16 healthy adult creole sheep were used. Animals were randomized to receive xylazine 0.2 mg/kg PC IM and ketamine 10 mg/kg PC IV (XK group), or a continuous infusion of 5% solution of xylazine (50 mg), ketamine (500 mg), and guaifenesin (500 mL) at a rate of 2.2 mL/kg/h IV (XKG group). Heart and respiratory frequency, rumen motility, and body temperature were evaluated before anesthesia, after induction, and during recovery. Induction was assessed by muscle spasms, nystagmus, and limb movement. Anesthesia was evaluated based on time, mandibular relaxation, skin sensitivity, and reflexes. Recovery was evaluated on a scale for anesthetic agent (0-10). Cardiorespiratory parameters decreased below baseline after induction of anesthesia in both groups. Between the groups, there was a significant difference in decubitus time (XK: 9.06 ± 0.73 min; XKG: 7.81 ± 0.53 min) and recovery (XK: 53.13 ± 5.3 min; XKG: 98.38 ± 5.71 min). Changes in the cardiopulmonary system were similar in both anesthetic regimens, and they were within acceptable clinical range. It is concluded that, in short surgical procedures, xylazine-ketamine anesthesia provides rapid induction, maintenance of physiological parameters within optimum limits, and rapid recovery.","PeriodicalId":21407,"journal":{"name":"Revue De Medecine Veterinaire","volume":"95 1","pages":"83-92"},"PeriodicalIF":0.0,"publicationDate":"2016-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83695795","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Liquid-liquid extraction of analyte with water, methanol, and centrifugation at 13500 rpm at 4 °C were performed. Separation and quantification were made using HPLC by reverse phase isocratic elution with a C18 column, fluorescence detector at 295 nm excitation and 490 nm emission, and a mobile phase consisting of water, acetonitrile, and triethylamine. Temporary plasma concentrations were analyzed with non-compartmental PK Solution 2.0 software. The results obtained indicate rapid absorption, as well as rapid and wide distribution. Cl and values of t½β and MRT indicate slow clearance and prolonged stay. The study evidenced plasma concentrations up to 24 h, which exceed the MIC of relevant pathogens. The AUC/MIC ratio indicates efficacy against microorganisms with MIC ≤ 0.15 μg/ml. Urinary levels of marbofloxacin are more significant than plasmatic levels.

Most mares demonstrate seasonally polyestrous behavior, by which they manifest estrus and ovulatory cycles during periods of higher daily luminosity. The annual reproductive cycle of mares is characterized by the presence of four phases defined by follicular dynamics: anestrous, spring transition, ovulatory, and autumn transition. During the phases of transition and anestrous, the incidence of ovulations decreases or is zero, making it difficult to synchronize ovulations between donors and recipients in preparation for embryo transfer. Some studies have shown that anovulatory/acyclic recipient mares managed with steroid-based protocols have similar uterine changes to those observed in pregnant mares. However, there is no sufficient research to allow to clarify the best steroid protocol with respect to dose, treatment times, and routes of administration.","PeriodicalId":21407,"journal":{"name":"Revue De Medecine Veterinaire","volume":"110 1","pages":"137-147"},"PeriodicalIF":0.0,"publicationDate":"2016-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80584138","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Algunos autores reportan que la arterioesclerosis es comun, pero de poca importancia en animales domesticos; ademas encasillan al perro (Canis lupus familiaris) como aterorresistente. Sin embargo, en la actualidad son varios los reportes de lesiones vasculares similares a las observadas en humanos, que estan relacionadas con la estrecha convivencia en su papel de mascota. Por tanto, la presente investigacion se enfoca en la busqueda y descripcion de lesiones histopatologicas concernientes a arterioesclerosis en perros, mediante un estudio retrospectivo de la casuistica del Laboratorio de Patologia Veterinaria de la Universidad Nacional de Colombia. Despues de revisar los informes de necropsia e histopatologia, se seleccionaron 52 casos de perros que reportaban uno o varios factores predisponentes para el desarrollo de arterioesclerosis; las laminas histopatologicas fueron inicialmente evaluadas con la tincion de hematoxilina y eosina y se capturaron fotomicrografias de utilidad para futuras investigaciones. En 23 de los 52 casos seleccionados se observaron diferentes caracteristicas de lesiones relacionadas con esta entidad, como vacuolas translucidas, paredes de aspecto hialino, proliferacion de tejido muscular o conectivo y deposiciones de mineral y pigmentos. Adicionalmente, en algunos casos se utilizo la coloracion tricromica de Masson para confirmar la presencia de tejido conectivo y muscular. Por ultimo, se plantearon hipotesis sobre la posible asociacion de diferentes factores (condicion corporal, edad, sexo, raza y enfermedad concurrente) con la presentacion de lesiones.","PeriodicalId":21407,"journal":{"name":"Revue De Medecine Veterinaire","volume":"159 1","pages":"79-89"},"PeriodicalIF":0.0,"publicationDate":"2016-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86389017","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
