Comparação entre as medidas morfométricas de equinos Mangalarga Marchador de marcha batida e marcha picada / Comparison between the morphometric measures of Mangalarga Marchador horses of batida marcha and picada marcha

The present study aimed to compare the morphometric measurements of Mangalarga Marchador horses of batida and picada marcha. Twenty-two linear and eight angular measurements of 222 males (130 of batida marcha and 92 of picada marcha) and 266 females (168 of batida marcha and 98 picada marcha) were compared in a completely randomized design, consisting of two treatments: horses of batida and picada marcha. The results were submitted to analysis of variance and means were compared by Fisher test (P<0.05). It was concluded that most of the measures of Mangalarga Marchador horses of batida and picada marcha have similar values, however, there are differences between some angles of members...

Oral microbiota of Brazilian captive snakes

The present work aimed to determine the oral microbiotic composition of snakes from São José do Rio Preto city, São Paulo State, Brazil. Ten snake species, comprising the families Boidae, Colubridae, Elapidae and Viperidae, were submited to microbiological examination of their oral cavity, which indicated positivity for all buccal samples. Gram-negative bacilli, gram-negative cocci bacilli, grambacilli and gram-positive cocci were isolated from the snakes. Among isolated bacterium species, the occurrence of coagulase-negative staphylococci in the buccal cavity of Crotalus durissus (Viperiade), Eunectes murinus (Boidae), Mastigodryas bifossatus (Colubridae) and Bacillus subtilis, common to oral cavity of Bothrops alternatus (Viperidae) and Phalotris mertensi (Colubridae), was detected. It was observed higher diversity of isolated bacteria from the oral cavity of Micrurus frontalis (Elapidae) and Philodryas nattereri (Colubridae), as well as the prevalence of gram-positive baccillus and gram-positive cocci. The composition of the oral microbiota of the studied snakes, with or without inoculating fangs, is diverse and also related to the formation of abscesses at the bite site in the victims of the ophidian accidents, and to pathogenic processes in the snakes that host these microorganisms

Tissue damage caused by Bothrops sp envenoming evaluated by magnetic resonance imaging (MRI)

The objective of this clinical study was to evaluate local tissue damage caused by Bothrops sp envenoming in relation to lesion type and damaged tissues using magnetic resonance imaging (MRI). Fifteen patients bitten by Bothrops snakes were treated at the Emergency Unit of the Tropical Diseases Unit at the University Hospital, Botucatu School of Medicine, UNESP, Säo Paulo State, Brazil. After receiving specific serotherapy, the patients were submitted to MR of the bite site. T1 spin-echo MRI were obtained revealing the following lesions: edema (n=9), edema associated with hemorrhage (n=5), and hemorrhage (n=1). Perimuscular areas (n=6) and subcutaneous tissues (n=5) were the most affected, followed by muscular tissues (n=4). It is important to mention that MRI did not show myonecrosis of the bite site, a widely reported finding in anatomical and histopathological experimental studies.

Estudo clinico do tremor. / Clinical study of tremor

Durante um periodo de 6 meses, 41 pacientes portadores de tremor nao associado com doencas neurologicas foram selecionadas.Aproximadamente 60% dos casos pertenciam ao grupo essencial-familial-senil, 30% associados ao alcoolismo cronico e o restante associado com tirotoxicose. O tremor pode ser dividido em tres tipos gerais: repouso, postural e intencional. O tremor de repouso e caracteristico do parkinsonismo, beneficiando-se com o uso de L. dopa. O tremor postural surge quando as extremidades sao sustentadas contra a gravidade, havendo beneficio com o uso de propranolol. O tremor intencional ocorre com o movimento e e caracteristico da doenca cerebelar, nao havendo beneficio com agentes farmacologicos. Breve revisao da literatura e feite dos subtipos
