Influência de atividades lúdico-desportivas na realização de equoterapia em pacientes neurológicos - ensaio clínico controlado aleatorizado

Introduction: Equine therapy is a therapy that uses horses to provide the practitioner in rehabilitation aspects of motor, sensory, behavioral and social. Objective: To investigate the effect of the combination of playful activities with hippotherapy sessions on the trunk balance and range of motion. Methods: We selected 18 practitioners diagnosed with cerebral palsy were randomly divided into two groups. The group 1 held hippotherapy sessions, and group 2 held equine therapy with recreational activities and sports. Before and after treatment, the trunk control and range of motion of the practitioners were evaluated. The data were analyzed using the Student’s t-test (p <0.05). Results: There was an improvement in range of motion and balance in both groups. Conclusion: Equine therapy is an effective treatment for individuals with cerebral palsy, regardless of accomplishing it with or without recreational activities.

Electroencephalographic Responses to a Noxious Surgical Stimulus in Mules, Horses, and Ponies

The aim of this study was to investigate the electroencephalographic (EEG) response of equidae to a castration stimulus. Study 1 included 11 mules (2 1/2-8 years; 230-315 kg) and 11 horses (1 1/2-3 1/2 years; 315-480 kg); study 2 included four ponies (15-17 months; 176-229 kg). They were castrated under halothane anesthesia after acepromazine premedication (IV [study 1] and intramuscular [study 2]) and thiopental anesthetic induction. Animals were castrated using a semiclosed technique (study 1) and a closed technique (study 2). Raw EEG data were analyzed and the EEG variables, median frequency (F50), total power (Ptot), and spectral edge frequency (F95), were derived using standard techniques at skin incision (skin) and emasculation (emasc) time points. Baseline values of F50, Ptot, and F95 for each animal were used to calculate percentage change from baseline at skin incision and emasculation. Differences were observed in Ptot and F50 data between hemispheres in horses but not mules (study 1) and in one pony (study 2). A response to castration (>10% change relative to baseline) was observed in eight horses (73% of animals) and four mules (36% of animals) for F50 and nine horses (82%) and four mules (36%) for Ptot. No changes in F95 data were observed in any animal in study 1. Responses to castration were observed in three ponies (75% of animals) for F50, one pony (25%) for F95, and all ponies for Ptot Alteration of acepromazine administration and castration technique produced a protocol that identified changes in EEG frequency and power in response to castration.

Developmental aspects of early pregnancy in mares

In mares, the embryo migrates to the uterus between days 5 and 6 postovulation beginning its mobility through all uterine segments, which is essential for the maternal recognition of pregnancy. During the mobility phase, the embryonic vesicle shows a linear growth rate until its fixation between days 15 and 17, when the orientation phenomenon occurs. From fixation to day 28 of pregnancy, the embryonic growth is less evident (plateau) by cross-section ultrasound examination. After this period the linear growth rate is reestablished until day 46. This plateau is attributed to the increased uterine tone that compresses the vesicle and to volume expansion, making it difficult to detect the conceptus growth only by the cross-section diameter. Around day 20, the embryo proper is visualized as an echogenic spot in the ventral aspect of the vesicle. Additionally, development of allantoic sac, embryonic heartbeat, yolk sac regression and posterior umbilical cord formation also can be visualized from days 20 to 40. An intimate interaction between uterus and conceptus is essential for the normal pregnancy development. Color-and spectral-Doppler ultrasonography can be useful for the evaluation of this interface. A gradual increase on uterine vascularity during the early pregnancy and transient changes in endometrial vascularity accompanying the vesicle location during the mobility phase have been described. Around day 38 of gestation, the formation of the endometrial cups begins and, consequently, the synthesis of the equine chorionic gonadotropin (eCG) induces the formation and development of supplementary corpora lutea, which are important to secrete progesterone and to maintain pregnancy until around day 120.

Effect of hemolysis on canine, bovine and earn e serum chemistry

Hemolysis is the main cause of biochemical analysis rejection's in veterinary laboratories, however the relative error caused by hemoglobin on serum biochemical profile has not been properly established on several species. In order to establish criteria for aproval and rejection of hemolyzed samples for serum biochemical tests, the hypothesis that hemolysis causes biochemical changes in canine, cattle and horses and that laboratorial error depends on species and hemolysis degree was tested. Thus, non-hemolyzed serum was contaminated with crescent hemoglobin levels and using commercial routine reagents, the serum concentrations of uric acid, albumin, cholesterol, triglycerides and urea, besides the activity of ALT, AST, CK and GUT were quantified in triplicate samples. The relative error was calculated by the comparison between hemolyzed and non-hemolyzed samples. Hemolys is did not cause significant error on the albumin determination in all three species, AST in canine and cattle, ALT in horses, UK and cholesterol in canine. There was a linear increase on uric acid levels in horses and cattle, triglycerides in all three species. A linear increase in serum urea in all species serum, UK and cholesterol in cattle and cholesterol in horses was observed. Serum AST activity on equine serum and ALT in cattle decreased linearly due to hemolysis. It was concluded that hemolysis promotes changes in canine, equine and bovine serum chemistry profile, however the laboratorial error not necessarily compromises the diagnosis in all cases, because the changes depends on species and degree of in vitro hemolysis.

Biotecnologias aplicadas à reprodução de éguas velhas

The acceptance of biotechnology for the most equine breeders association had a significant effect in the horse industry, gaining popularity around the world, because the increasing on the genetic gain, allowing the use of sub fertile mares and stallions with high genetics value on reproduction. The embryos in vitro production of human and cattle has been used with success, however in vitro embryo production is not efficient in the horse, as oocyte transfer (OT) and intracytoplasmatic sperm injection (ICSI). The oocyte transfer has been used especially in subfertile old mares presenting reproductive pathologies as: endometrite, cervical and uterine adhesions, blocked oviduct, perineal laceration and ovulation failures. During oocyte recovery process, the oocytes must be collected from immature follicles that need be matured in vitro or in vivo matured oocytes from pre-ovulatory follicles through the transvaginal aspiration guided by ultrasound. The recovered oocyte is transferred to a previously inseminated recipient mare, through the flank laparotomy. The intracytoplasmatic sperm injection (ICSI) is a procedure of in vitro fertilization that needs only one sperm that is aspirated and injected inside the oocyte. The oocytes used, can be from mature and immature follicles. Fresh, cooled and frozen semen can be used, because the procedure not requires a functional sperm. The use of Piezo drill resulted in a breakthrough the pellucid zone, allowing the vibration per minute provided in the sperm injection pipette, a major result of cleaved oocytes, due to a better sperm injection in the oocyte. The embryo transfer can be straight inside the oviduct, as also transcervical transferred after embryo culture produced in vitro. In conclusion both procedures (OT and ICSI) are effective to be used on equine assisted reproduction, getting results even lower than expected, but satisfactory from animal genetically superior

Principais métodos terapêuticos na tendinite eqüina

Most athletic horses nowadays suffer injuries on their locomotor system, needing a long period of rest during the year, meaning a big economic loss. Because of that, this kind of injury has become extremely important for the Veterinary Medicine. Among this injuries, tendinitis of the flexors tendons must be mentioned, since its reparation is essential for the animal return to exercise. Many methods of treatment for this injury have been employed, but few have provided satisfactory results. So the objective of this study is to analyze the present concepts of equine tendinitis to better understand its mechanism, adequate treatment and prevention

Uso da morfina na analgesia de equinos

Pain control is an important aspect of equine medicine. Musculoskeletal and gastrointestinal diseases are the most important clinical and surgical painful situations in this specie. In these cases, opioids have been used successfully for the treatment of pain, administered both local (intra-articular and epidural) and systemically. Otherwise, opioids, specially mu agonists like morphine, present important side effects in horses. Amongst these effects, CNS stimulation with increased motor activity and impairment of intestinal motility are observed in several cases. Therefore, adequate dosing of administration are essential for the safe use of opioids in horses

Análise física da estrutura do tecido ósseo bovino

There are diseases in vertebrates associated with the structure of bone tissue that directly affect the locomotor system of the animal. Being a endoskeleton, the diagnosis of these diseases becomes difficult in vivo. The characterization of the physical structure of the bone tissue of healthy animals becomes a major tool in the diagnosis comparison of live animals. Thus, the objective of this work is to determine the average value of the key physical properties of the bone structure used in the clinical diagnosis, such as: bone density, porosity, and mass attenuation coefficient of 59.6 keV photons of bone tissue and bovine and equine check variations in these values. The samples were provided by the pathology department of the Faculty of Veterinary Medicine and Zootechny of Botucatu-SP, which are of one male equine and one female bovine animals, using the radio and metacarpus, together with these materials were supplied the historic them. They were withdrawn ten samples in cuts of 10cm over the bone . These samples were submitted to the wet method of immersion in water for the density, by the method of attenuation of gamma radiation of radioisotope 241Am, it is estimated the mass attenuation coefficient, and then were dried in the oven for determining the content moisture. In determining the porosity of the samples was tight ground, in order to obtain the density of particles. The results for the mass attenuation coefficient of gamma radiation to the levels of saturated humidity, environment humidity, dry humidity respectively 0289 ± 0039; 0286 ± 0040 and 0297 ± 0042. And the density of particles was 2.2691 g/cm3

Criopreservação de sêmen de epidídimo de garanhões

It is a fact that Brasil has a featured position in the equine market due to the size and the high quality of its squad. To keep the competitivity, the reproduction biotechnologies have a big and important role. The cryopreservation of stallion semen, for example, generates innumerous advantages, which includes: larger number of obtained doses, storing genetic material for undetermined time, using the semen of a good stallion even after its dead or any other event that makes both semen collection and mating impossible, etc. In this context, the cryopreservation of epididymal sperm, has been seen as a promising technique in equine reproduction. The epididymal cauda has a significant quantity of fertile spermatozoa and this ensures a huge store of cells in cases of unexpected accidents, which can early interrupt with the reproductive life of a stallion. Lots of studies are being developed using the cryopreservation of stallion epididymal sperm. These studies permit the propagation of high quality genetic material and make possible for the stallion owner to opt for a final semen collect in unexpected circumstances
