Tratamento cirúrgico de condroma extradural lombar em cão - relato de caso

Neoplasms originating in the spinal canal are uncommon in small animal veterinary clinic, but when present can cause significant neurological signs. Anatomically, these neoplasms can be classified as extradural, intradural-extramedullary and medullary. Extradural neoplasms are located outside the dura mater, but they can cause compression of the spinal cord. The chondromas are benign neoplasms characterized by the formation of cartilage and is rarely located in the spinal canal in both human and veterinary medicine. We describe a case of lumbar extradural chondroma in a dog that surgical decompression and removal of the mass allowed the resolution of clinical signs of paralysis with return of function of the hind limbs of the patient.

Quantificação de ácidos graxos de alevinos de tilápia do Nilo (Oreochromis niloticus) alimentados com diferentes fontes de óleos vegetais

The present work aimed to quantify the fatty acids in total lipids of Nile tilapia fingerlings (Oreochromis niloticus) fed with different sources of vegetable oils mechanically extracted. Were used 320 tilapias (O. niloticus) with average initial weight and average total initial length of 2.55±0.57 g and 5.59±0.43 cm, respectively, fed for a period of 60 days, in a randomized block design with eight treatments and four replications. The diets were prepared with 320 g/kg crude protein and 3.500 kcal of digestible energy per kg of feed enriched with eight different oils: sunflower, canola, sesame, linseed, peanut, Para's nut soy and macadamia, with an addition of 4%. Among the major fatty acids the oleic, palmitic, linolenic and linoleic were obtained in higher concentration (mg/g of LT) in fish from all treatments. The sums of polyunsaturated fatty acids after 60 days of cultivation had increased in all treatments compared to the 30 days of the experiment. This is due to the addition of oils with high contents of n-6 and n-3 fatty acids. The fatty acids in the carcass are a reflection of the energy source of oil used. As a conclusion it is recommended the use of linseed oil in the diet of tilapia fingerlings due to great improvement in the relationship between n-6/n-3.

Ultrassonografia oftálmica em cães com diferentes conformações cranianas

The aim of this study was to establish mean values for intraocular structures and analyse if the differences are present for different skull conformations in dogs. In this study, 30 dogs were selected and distributed into three groups according to skull conformation; thus, group 1 (G1) was composed of brachycephalic dogs, group 2 (G2) was composed of mesocephalic dogs and group 3 (G3) was composed of dolichocephalic dogs. A and B-mode ultrasound was performed simultaneously for obtainment of measurements relating to anterior chamber depth (D1); lens thickness (D2); vitreous chamber depth (D3); and the axial length of the eye (D4). No differences were observed when comparing left and right eyes of dogs within the same skull conformation group (p>0.05). Differences were observed when comparing D3 and D4 between groups G2 and G3 (p<0.05). Skull conformation of brachycephalic dogs did not influence intraocular measurement values when compared to dolicephalic and mesocephalic dogs. Skull conformation of dolichocephalic dogs had an influence in values of vitreous chamber and the complete length of the eye when compared to mesocephalic dogs.

Correction of rectal sacculation through lateral resection in dogs with perineal hernia ? Technique description

The occurrence of perineal hernias in dogs during routine clinical surgery is frequent. The coexistence of rectal diseases that go undiagnosed or are not correctly treated can cause recurrence and postoperative complications. The objective of this report is to describe a surgical technique for treatment of rectal sacculation through lateral resection in dogs with perineal hernia, whereby restoring the rectal integrity.

Calcium aluminate cement: Used in bone defects induced in the femur of rabbits

The patterns of the calcium aluminate cement in bone defects experimentally induced in the femur of 12 New Zealand White rabbits were evaluated. The animals were distributed in three experimental groups, corresponding to postoperative observation periods of 15 (G15), 30 (G30) and 60 (G60) days. Clinical, surgical, radiographic and histological appraisals were made to observe the osteoinductor and osteoconductor potential of the biological material, as well as the bone integration. The calcium aluminate cement formulation was biocompatible, but has not acted as a osteoconductor or osteoinductor.

Kinetic study of pyrolysis of castor beans (Ricinuscommunis L) presscake: an alternative use for solid waste arising from the biodiesel production

This work investigated the effects of temperature and of rate of heating on the kinetic parameters of pyrolysis of castor beans presscake, a byproduct generated in the biodiesel production process. Pyrolysis process was investigated by thermogravimetric analysis, and parameters were obtained from nonisothermal experiments. The results obtained from the process of thermal decomposition indicated the elimination of humidity and the decomposition of organic components of the biomass. DTG curves showed that the heating rate affects the temperature of maximum decomposition of the material. Kinetic parameters such as activation energy and pre-exponential factor were obtained by model-free methods proposed by Flynn–Wall–Ozawa (FWO), Kissinger–Akahira–Sunose (KAS), and Kissinger. Experimental results showed that the kinetic parameters values of the FWO and KAS methods display good agreement and can be used to understand the mechanism of degradation of the cake. In a generalized way, the results contribute to better understanding of the processes of biomass pyrolysis.
