Estudo da resposta alérgica à tuberculina em ovinos (Ovis aries) experimentalmente sensibilizados, conforme a região corpórea e a dose de PPD utilizada / Study of the allergic response to tuberculin in sheep (Ovis aries) experimentally sensitized, according to body region and PPD\'s dose used.

Silva, Danielle Yuri Massukado Rodrigues da 20 August 2010 (has links)
Diante da importância do tema, a pobreza de dados nacionais sobre a tuberculose em ovinos e a necessidade de aprofundamento de conhecimento sobre a aplicação das técnicas de diagnóstico pertinentes ao combate e erradicação da tuberculose animal, foi delineado o presente estudo. Esta pesquisa visou avaliar a melhor região corpórea e dose de derivado protéico purificado (PPD) bovino a ser aplicada em ovinos (Ovis aries) experimentalmente sensibilizados comMycobacterium bovis AN5 para diagnóstico de tuberculose. Utilizou-se 15 ovinos clinicamente sadios e negativos à prova de Tuberculina Cervical Comparativa (TCC), segundo os padrões estabelecidos por Cyrillo et al. (2007), em duas fases: primeira etapa avaliação do melhor local de aplicação do PPD bovino em ovinos; segunda etapa a partir do melhor local de aplicação, a dose de PPD bovino a ser aplicada. Imediatamente após a leitura do TCC de triagem inicial, os ovinos foram sensibilizados com o inóculo inativado de M. bovis estirpe AN5, e após um período de dessensibilização de 60 dias entre aplicações, realizou-se a avaliação de cinco regiões corpóreas, com a mensuração da espessura da dobra de pele efetuada nos momentos antes (0h) e após aplicação (12h, 24h, 48h, 72h e 96 horas). As análises estatísticas mostraram uma significância para os melhores locais de aplicação, a saber: regiões torácica dorsal, seguida da cervical média e abdominal dorsal em 48 e 72 horas após aplicação de PPD bovino. Eleita a região torácica dorsal (p=0,94) como o melhor local de aplicação, os resultados da reação frente às diferentes doses (0,05 mL; 0,1 mL e 0,2 mL), expressos em espessura da dobra de pele, indicaram que não houve diferenças significantes entre as doses e momentos de leitura, sendo recomendada a aplicação de 0,1 mL de PPD bovino e leitura com 72 horas após aplicação. / Given the importance of the topic, the paucity by National data of tuberculosis in sheep, and the need to deepen knowledge about diagnostic techniques application relevant to combat and eradication of animal tuberculosis, the present study was designed. This study aimed to evaluate the best body region and dose of bovine purified protein derivative (PPD b) to be used in sheep (Ovis aries) experimentally sensitized to Mycobacterium bovis AN5 to tuberculosis diagnoses. It was used 15 clinically healthy sheep and negative to the Comparative Cervical skin Test (CCT), according to standards established by Cyrillo et al. (2007), in two phases: first part - assessment of the best application area of bovine PPD in sheep; second part - from the best sites for the application, the best dose of bovine PPD to be applied. Immediately after reading the initial screening CCT, the animals were sensitized with the inoculation of inactivated M. bovis strain AN5, and after a 60 days period of desensitization between applications, was carried out an assessment of five body regions, the skin fold thickness was measured before (0h) and after injection (12h, 24h, 48h, 72h and 96 hours). Statistical analysis showed significance to the best site of application: dorsal thoracic region, followed by middle cervical and dorsal abdominal, according to 48 and 72 hours after injection of bovine PPD. Chosen the thoracic region (p = 0.94) as the best site for the application, results of reaction from different doses (0.05 mL, 0.1 mL, and 0.2 mL), expressed as skin fold thickness showed no significant differences between doses and times of measurement, it was recommended the application of 0.1 mL of bovine PPD and measure at time 72 hours after injection.

Depictions of Female Body Types in Advertising: How Regional Visual Attention, Body Region Satisfaction, Media Influence, and Drive for Thinness Relate

Adams, Dallin Russell 02 March 2020 (has links)
Through continuing technological advancement, increased media exposure occurs as consumers are able to obtain access more easily. Various media formats, including video, are a means whereby consumers gather information about the world around them, and continually make comparisons between that information and themselves. Among the information obtained from media channels is how bodies are portrayed in the media. Comparisons between media images of body and self-perceptions of body are particularly prevalent in women. The current study employs the use of eye-tracking to examine how women view other women's body types and areas of the body in video-based advertising. The study also employs self-report measures to further understand how individual body region satisfaction, drive for thinness, and media influence relate. Findings indicate that women, regardless of personal satisfaction, tend to look longer at thin women than plus-sized or average women. Furthermore, media pressures and internalization were found to play a strong role in women's drive for thinness and personal satisfaction, while media as a source of information played no such role.
