Efficacy of the d-phenothrin/pyriproxyfen association against mites in naturally co-infested rabbits

O objetivo do presente estudo foi avaliar a eficácia da associação de d-fenotrina e piriproxifen no controle de infestações simultâneas por Psoroptes ovis, Cheyletiella parasitivorax e Leporacarus gibbus em coelhos naturalmente co-infestados. Vinte coelhos mestiços (Nova Zelândia Branco x Califórnia) infestados simultaneamente pelas três espécies de ácaros foram divididos aleatoriamente em dois grupos. Todos os coelhos infestados por apresentavam eritema, hiperemia e formação de crostas nas orelhas, causados por P. ovis. Infestações simultâneas por C. parasitivorax e L. gibbus foram considerados assintomáticas em todos os animais. Dez animais foram tratados com uma formulação spray contendo d-fenotrina a 4,4% e piriproxifen a 0,148%, pulverizando toda a superfície corporal de forma uniforme, incluindo a face interna das orelhas. Os outros 10 coelhos não foram t ratados, sendo mantidos como grupo controle. Os animais foram avaliados nos dias 7, 14, 21, 28 e 35 pós-tratamento. A associação de d-fenotrina e piriproxifen foi 100% eficaz no controle das três espécies de ácaros e foi responsável pela remissão das lesões de sarna psoróptica nos animais tratados. Não foram observados sinais de intoxicação. Os resultados indicam que a formulação spray de d-fenotrina e piriproxifen em uma única aplicação é uma opção clinicamente segura e eficaz no controle de infestações por ácaros em coelhos.

Effect of testicular thermoregulation on the quality of buffalo sperm

The process of spermatic division and differentiation (spermatogenesis) occurs with intratesticular temperature lower that the corporal temperature and for that is essential that the testicular thermoregulation mechanism occurs properly. For evaluation of the scrotal surface temperature can be used the infrared thermography or testicular sensors, besides that, can be evaluated the blood flux in the spermatic cord through the Doppler ultrasonography. Thus, the aim of this study is to analyze the testicular thermoregulation in adult buffaloes through scrotal thermography and Doppler ultrasound of testicular artery and verify its effect on sperm quality. For that were used seven healthy buffaloes, with age of 3 and 4 years, of the Murrah breed. The animals were subjected to 3 semen collections using artificial vagina, with one day of interval. In addiction, the retal temperature measurement (RT) with dry bulb thermometer, the measurement of scrotal surface temperature (SST) and body surface temperature (BST) through infrared thermography and the pulsatility (PI) and resistivity (RI) index of testicular artery by Doppler ultrasonography, were performed using 2 distinct moments: animals previously placed to shade (M1) and animals subjected to 4 hours of sun (M2). All parameters were compared by T test and the correlations were performed by Pearson test using the In Stat Graph Pad 3 (R) program. The significant level considered was 5%. There was an increase (p<0,05) of RT, SST, SNT and RI in M2. increasing trend was observed (0,05>p>0,01) PI and RI between M1 and M2. There was a low correlation between SST and semen quality. The results of this study allow us to conclude that adult buffaloes have low ability to perform body and testicular thermoregulation in situations of enviromental heat stress. However, this low capacity of testicular temperature maintenance demonstrated no correlation with the sperm kinetic parameters and sperm morphological defects in buffalo spermatozoa.

Perfil epidemiológico dos pacientes internados na unidade de tratamento de queimaduras do Hospital Estadual de Bauru

Burns are frequent accidents, and they are among the major causes of morbidity and mortality in our society. In Brazil, statistical data on such lesions are relatively scarce, and they are concentrated in a few treatment centers. Data on such accidents allow for specific care to be timely and properly taken in order to provide patients with a better prognosis, in addition to enabling the development of prevention programs as well as fire-prevention safety laws. To characterize the epidemiological profile of users at the Burn Treatment Unit of Bauru State Hospital. Collection of epidemiological data through the e-pront system and from charts of burned inpatients from April 2005 to April 2010. During the studied period, 906 hospitalizations of burned patients occurred, with an annual average of 181.2 individuals. Their mean age was 28.4 years, with a predominance of males. The mean hospitalization period was of 27.6 days, with a median of 16 days and a maximum of 216 days; 14.7% developed to death, with the highest mortality rate in the first two weeks of hospitalization. Second-degree burns were the most frequent; 36.8% of the patients burned less than 10% of their body surface, and there was a gradual frequency reduction when a larger burned surface was taken into account; the greater the affected areas, the higher the number of deaths; 91% resulted from thermal agents, 6% from electric and 2% from chemical agents; scalding was the major cause among all agents, followed by alcohol associated with fire and direct flame. The major area affected areas were the upper limbs. The study shows the need for educational and preventive measures, particularly for the young adult population, by means of educational programs and prevention campaigns

Acupuntura na abordagem da Síndrome da Cauda Equina em pequenos animais Trabalho

Nowadays, in any area that acts within the veterinary medicine, we talk a lot of specialists. Specialists in neurology, cardiology, dermatology, endocrinology, finally, more specialized in a subject, better is the veterinarian. However, on one hand to deepen the knowledge helped in the discovery of new diagnostics and treatments, secondly, a bit lost sight of the patient as a whole. Traditional Chinese medicine, one of whose branches is acupuncture, is aimed at exactly this approach to be fully alive, where all body is interconnected and the disease is not seen as the imbalance of one system, but, as the imbalance between our being and the environment external. Acupuncture is an alternative in the treatment of many diseases, among them Cauda Equina Syndrome, and consists of stimulating specific points on the body surface, which help the body return to its natural harmony. A Cauda Equina Syndrome is a frame subsequent to a neuromuscular spinal cord at the level of the spinal canal of the lower lumbar spine and sacral, whose treatment is almost always surgical. This study aims to show the relevance of acupuncture treatment in this condition and report the importance of the philosophy of traditional Chinese medicine nowadays, even when their arms are not in the treatment of choice

Thermoregulatory consequences of salt loading in the lizard Pogona vitticeps

Previous research has demonstrated that dehydration increases the threshold temperature for panting and decreases the thermal preference of lizards. Conversely, it is unknown whether thermoregulatory responses such as shuttling and gaping are similarly influenced. Shuttling, as an active behavioural response, is considered one of the most effective thermoregulatory behaviours, whereas gaping has been proposed to be involved in preventing brain over-heating in lizards. In this study we examined the effect of salt loading, a proxy for increased plasma osmolality, on shuttling and gaping in Pogona vitticeps. Then, we determined the upper and lower escape ambient temperatures (UETa and LETa), the percentage of time spent gaping, the metabolic rate ((V) over dot(O2)), the evaporative water loss (EWL) during gaping and non-gaping intervals and the evaporative effectiveness (EWL/(V) over dot(O2)) of gaping. All experiments were performed under isotonic (154 mmol l(-1)) and hypertonic saline injections (625, 1250 or 2500 mmol l(-1)). Only the highest concentration of hypertonic saline altered the UETa and LETa, but this effect appeared to be the result of diminishing the animal's propensity to move, instead of any direct reduction in thermoregulatory set-points. Nevertheless, the percentage of time spent gaping was proportionally reduced according to the saline concentration; (V) over dot(O2) was also decreased after salt loading. Thermographic images revealed lower head than body surface temperatures during gaping; however this difference was inhibited after salt loading. Our data suggest that EWL/(V) over dot(O2) is raised during gaping, possibly contributing to an increase in heat transfer away from the lizard, and playing a role in head or brain cooling.
