Marcus Vinicius Henriques de Carvalho | André José Fruchi | Evaldo Marchi
The present study objective was to determine whether ventilation of rats with room air is possible and whether this technique has advantages when compared to pure oxygen ventilation. Twenty rats were divided into two groups of ten animals each. In one group, the animals were ventilated with cylinder of compressed air, 0.21 of oxygen, (air group), while the other group animals were ventilated with cylinder of compressed oxygen, assumed 1.00 of oxygen, (O2 group). Blood gas parameters and oxygenation index were compared between groups. The O2 group had hyperoxia at the beginning and end of artificial ventilation. The PaO2 were adequate in animals of air group. No significant difference in PaCO2 was observed between the two groups at the beginning or end of mechanical ventilation. The mean oxygenation index (PaO2/FiO2ratio) was significantly higher in the air group compared to the O2 group at the beginning and end of artificial ventilation (5 min: p < 0.001 and 60 min: p < 0. In conclusion, ventilation of rats with room air is more advantageous than with pure oxygen since it permits adequate oxygenation without causing hyperoxia.

Macacos-prego (Sapajus sp), inesperadamente, compartilham com chimpanzés comportamentos como alta cognição e memória, uso de ferramentas com o bipedalismo intermitente, tolerância social. No entanto, sua anatomia ainda é pouco estudada. Para verificar a hipótese com qual espécie e/ou grupo de primatas os macacos-prego compartilham mais características, o objetivo deste trabalho foi estudar os nervos pélvicos do Sapajus e compará-los com dados da literatura anatômica sobre os seres humanos, chimpanzés e babuínos, considerando aspectos como origem, trajetória e estruturas inervadas. Foi observado que existem grandes variações nos nervos pélvicos entre os primatas estudados aqui, quais sejam, 1) o problema da posição anatômica, i.e., alguns primatologistas consideram a posição anatômica humana para os primatas, outros consideram a posição anatômica animal, e a opção por um ou outro não é clara nos textos; 2) o problema dos membros pélvicos em primatas não humanos serem lateralizados e semi-fletidos em relação aos seres humanos modernos; 3) o problema da ausência, nos seres humanos modernos, de alguns músculos da coxa em relação aos outros primatas como o escansório e o iliosquiofemoral; e 4] o problema da diferença do número de vértebras nos primatas estudados aqui, inclusive com diferenças para a mesma espécie citadas por diferentes autores tanto para chimpanzés como para macacos-prego.

Hemangiosarcoma (HSA) is a malignant neoplasm originating from the vascular endothelium, with high metastatic power and commonly described in the spleen, liver, and right atrium. Thus, the objective of the present study is to report the occurrence of HSA at the base of the left atrium of a male, elderly, Lhasa Apso dog, treated with cyanosis, orthopedic position, cough. In the physical examination, the presence of crackling was observed in pulmonary lobes, murmur in focus of mitral and tricuspid grade IV\VI. The recommended emergency therapy was performed until the clinical improvement of the animal. After echocardiography, mitral and tricuspid valvular degeneration was confirmed, as well as the presence of an irregular, mixed echocardiogram, extra-cardiac, immobile at the base of the left atrium, measuring 2.9 x 1.44 cm in diameter. The clinical therapy established stabilized the clinical picture for 128 days, with recurrence of pulmonary edema and severe hemorrhagic pleural effusion, with the owners opting for euthanasia of the animal and necropsy confirming the definitive diagnosis of extrahepatic SAH at the base of the left atrium.

A study has been conducted to investigate the effect of two local herbs in Indonesia; Areca catechu nut and Sauropus androgynous leaf, combined with mineral block to treat gastro intestinal nematode in goats. A.catechu is well known to have anthelmintic property due to its alkaloid and tannin content, and S.androgynus also contains tannin, alkaloid and steroid that will enhance the anthelmintic property of those herbals. As many as 80 goats had been divided into 4 groups; 20 were treated with albendazole (Group A), 20 were given A.catechu and S.androgynus (Group B), 20 were given combination of A.catechu, S.androgynus, and mineral block (Group C), and 20 as negative control (Group D). The result revealed that herbal treatment showed significantly effective toward nematodes in gastro intestinal, demonstrated by declining egg worm of Group B and C. Body weight improvement and overall performance in Group C was higher compared to other groups. However, goats treated with albendazole showed slightly better results in the decreasing amount of egg worms found after treatment. Nevertheless, A.catechu and S.androgynus are potential anthelmintic herbal; combination with mineral block will enhance the anthelmintic activity. Therefore they are good options for treating helminthiasis in livestock.

The aim of this study was to identify the prevalence of fasciolosis of Simeulue’s buffalo using macroscopic approach by observing pathological changes in the liver. The sample were obtained from slaughterhouse in Sinabang. A number of 60 livers were obtained on July to September 2015 based on post mortem examination. From this sample, a total of 57 livers were found positive indication of infested by F. gigantica (95%). The length and width of F. gigantica was 25 mm and 7 mm. The body was flat as a leaf, blunt on posterior, gray, brown, transparant and do not have a real shoulder shapes. The liver which were not infested with F. gigantica showed sharp edges and a very high degree of elasticity. On the other hand, in the infested liver was found F. gigantica in the bile duct and showed a color of pale, the dark brown exudate as well as objects looks like gravel. The buffaloes sample were supplied to the abattoir from the paddy fields or oil palm plantations area. In comparison, the buffaloes raised in both areas were not different on the pathological changes of liver. In conclusion, this study showed that simeulue’s buffalo is very prevalence to F. gigantica.
