The aortic valve was investigated in 58 sheep and 60 swine without heart disease.After fixation in 4% formalin, the distance between the ostia and the elements of the right/left aortic sinuses was measured. For the left coronary ostium (LCO), it was found that in sheep 81% were below and 19% at the level of intercomissural line (IL). In pigs, 88.3% were below and 11.7% at the IL level. In sheep, the OCL was close to the right valve commissure (CVR) in 98.3% and close to the left valve commissure (CVV) in 1.7%. In pigs, it was close to RVC at 83.3% and close to LVC at 16.7%. Regarding to RCO, it was found that in sheep 69% was below, 1.7% was above and 29.3% at the IL level. In pigs, 20% were below, 15% above and 65% at the IL level. The distance of the RCO in relation to the valve commissures was 56.9% close to LVC and 43.1% close to RVC in sheep. In pigs, 81.7% were close to LVC and 18.3% close to RVC. The position of LCO was balanced between sheep and swine, while the RCO in swine was closer to CVE when compared with sheep. The accessory coronary ostium was observed in 18.6% of sheep and 10% of pigs. Thus, it is concluded that in sheep and swine the left coronary artery is perfused only in ventricular diastole. Perfusion of the right coronary artery occurs more frequently in diastole and less frequently in ventricular systole.

Em 2007 a cidade de Cajazeiras-PB recebeu a implantação do curso de Medicina pela Universidade Federal de Campina Grande. Neste processo, os docentes se depararam com várias dificuldades. Para propor melhoras e até, suplementação da carga de conceitos em Anatomia Humana, foi criada uma atividade didática chamada "Desafio Anatômico", no qual os discentes eram instruídos a confeccionar modelos anatômicos que fossem didáticos a ponto de serem usados nas aulas, auxiliando o conteúdo da disciplina. Após a apresentação dos trabalhos, os discentes mostraram-se satisfeitos com os resultados, sobretudo sob o ponto de vista de transmissão de conhecimento e absorção de conteúdo. Desta maneira, esta experiência mostrou-se positiva e singular para o processo de ensino-aprendizagem da anatomia no curso médico, pois a mesma estimulou de diversas formas a criatividade, memória e trabalho em grupo dos participantes.

ResumoO objetivo do presente trabalho foi avaliar a inervação do músculo diafragma em gatos, proveniente dos nervos intercostais, contradizendo diversos autores que afirmam ser este músculo inervado apenas pelos ramos dos nervos frênicos direito e esquerdo. Foi observado que existe a frequência de nervos dispostos entre o 8º e o 11º espaços intercostais.Palavras-chave: Gato. Diafragma. Nervos intercostais. AbstractThe knowledge of organism's anatomy is essential to conduct any experiment or study with itself. Based on that, we decided to analyze and study in details the innervation of the diaphragm muscle from intercostal nerves in cats. It goes beyond other authors' analysis that describes only the innervation from phrenic nerves. Despite we have got a range of results, we observed a major frequency of eighth to tenth intercostal nerves going to diaphragm muscle.

ABSTRACT:Malnutrition remains an important public health condition by affecting mostly children. The present study aimed to examine the effects of prenatal protein undernourishment and postnatal renourishment on the metabolism of pre-adult animals. Forty-five male Wistar rats originating from different litters were used. The Nourished (N, n=15) and Undernourished (U, n=30) groups were maintained on proteic and hypoproteic diets (20% and 5% casein, respectively) from the intrauterine phase until the end of the experiment. The Renourished group (R) contained 15 animals, randomly chosen from U group, that consumed the N diet beginning on day 21 (weaning). All groups were maintained until day 60. The experimental data was acquired daily for body weight, feed and water intake, feces and urine excretion. Data analysis was made with the total results and the ratio between them. The U group animals developed uniformly sparse hair late and experienced intense sweating, features that were not observed during the experiment in the R and N animals groups. The R group had the largest weight gain and feed and water intake ratio/weight at experimental period, followed by the N group animals. The final body weight and food intake decreased gradually in the order N-R-U, but none of the other parameters showed a statistical difference between the N and R animals. Compared to groups N and R, the U group animals consumed 90% and 81% more food and water, respectively. Protein undernourishment induced metabolic dysfunction in the U group animals. The similarity in the experimental parameters of the N and R groups suggests that an early feeding correction was effective in reestablishing the organic functions of the R group animals.

O objetivo deste estudo foi verificar as dimensões, massa e volume do baço em tartarugas (Trachemys scripta elegans WIED, 1839) estabelecendo correlação com as dimensões, massa e volume corporais. Para a confecção deste trabalho, utilizou-se vinte animais, provenientes do Instituto de Psicologia da Universidade de São Paulo, coletados após a eutanásia que, levados ao Laboratório de Anatomia da Faculdade de Medicina Veterinária e Zootecnia da mesma universidade, tiveram suas dimensões, massa e volume corporais aferidos. Então, retirou-se o plastrão, expondo sua cavidade celomática, removendo o baço para realizar as mensurações. Apesar dos animais terem sido criados num mesmo ambiente, sob as mesmas condições ambientais e abatidos no mesmo período do ano, concluiu-se que não há correlação entre as dimensões do baço e as dimensões corporais, onde, animais menores podem apresentar o baço com maiores proporções do que tartarugas maiores, variando conforme as condições individuais - fato que ocorre com as demais espécies animais.
