Estudo das alterações hematológicas e urinárias em cães em diferentes estágios de disfunção renal e avaliação do biomarcador cistatina C

Chapter 2 - Cystatin C is a cationic protein is not glycosylated, produced a steady state for all nucleated and present in biological fluids cells being freely filtered by the glomeruli and almost completely catabolized in the proximal tubule, it is a promising early renal dysfunction marker. This study aimed to determine and compare the serum concentration of cystatin C biomarker in 86 dogs. The animals were divided into four groups according to serum creatinine levels: G1 - up. 1.4 mg / dL (23 animals), G2 - 1.5-2.0 mg / dL (16 animals), G3 - 2.1 to 5.0 mg / dL (24 animals) and G4 - above 5.1 mg / dL (23 animals). There was the measurement of the parameters used in the clinical routine of small animals such as urea, urinary gamma glutamyl transferase, proteinuria, alkaline phosphatase, sodium, potassium, chloride, calcium, phosphorus, calcium/phosphorus ratio and cystatin C. There was no statistical difference for urea, proteinuria, phosphorus, calcium/phosphorus, potassium and cystatin C, however, the other showed no statistical difference. Based on the results we can infer that cystatin C was not a good early indicator of kidney disease in dogs. Chapter 3 - This study aimed to determine the hematological and urinalysis elements such as density, proteinuria, cylinders and pH in 86 dogs The animals were divided into four stages according to serum creatinine levels: I - up to 1.4 mg/dL (23 animals), II - 1.5-2.0 mg/dL (16 animals), III from 2.1 to 5.0 mg/dL (24 animals) and IV - above 5.1 mg/dL (23 animals). In stage III, IV there was anemia normocytic normochromic type. Stage II had a leukocytosis frame by neutrophilia with a regenerative left shift and stage III and IV detour degenerative left. The density remained within the reference values all stages. Proteinuria showed statistical significance for the classification 2+ (1.0 g/L), between stage I and II, II and IV. Only the cylinder granular statistical difference in the classification 2+ between stage II and III, and 3+ between stage I and III. The prevailing pH was acid. The haematological values compared to serum creatinine stages showed the changes in hemoglobin and packed cell volume erythrocytes become more pronounced as serum creatinine values rise , this is also the behavior of neutrophils rods and proteinuria.

Morfometria dos forames mandibular, mentual e infraorbital de Lobo-guará Chrysocyon brachyurus, Illiger, 1815 aplicada a bloqueios anestésicos

CHAPTER II - The Chrysocyon brachyurus is the biggest South American canid which has a high frequency of dental injuries, both in wild and captivity. Thus, veterinary procedures are necessary to preserve the feeding capacity of hundreds of captive specimens worldwide. The aim of this study was to study the mandibular morphometry of maned wolf with emphasis on the establishment of anatomic references to the anesthetic blockage of the inferior alveolar and mental nerves. Therefore, 15 measurements in 22 hemimandibles of C. brachyurus adults were taken. For extra-oral technique of blockage of the inferior alveolar nerve at the level of the mandibular foramen, it is stated that the needle should be advanced, close to the medial surface of the mandibular ramus, by 11.4 mm perpendiculary from the palpable concavity. Alternatively, the needle can be introduced for 30.4 mm from the angular process at 20-25 degrees angle with the ventral margin. For blocking only the mentual nerve, it is recommended the introduction of needle for 10 mm, close to the lateral aspect of the mandibular body, at the level of the lower first premolar. The mandibular foramen showed similars position, size and symmetry in the maned wolfs specimens examined. The comparison of the data with those available for other carnivores reflects the necessity for determining these anatomical references specifically for each species.

Perfil sorológico contra Rickettsia spp e Leptospira spp e infestação de carrapatos em suínos mantidos sob diferentes sistemas de criação

The various types of pig farming, intensive and extensive, expose them to pig parasites but also to those from the environment of the breeding site. In this work was evaluated the exposure of bigs bred in technified farms, SISCAL (intensive breeding system in pens) and not technified (backyard) to leptospira, ticks and rickettsiae. Blood sera were analyzed to determine titers of antibodies anti-Leptospira by SAM technique and antibodies anti-rickettsial by IFA, pigs were inspected for ticks and in their breeding environment and surrounding areas (pastures and riparian vegetation), ticks were collected by the flannel dragging technique. In the farms of pigs 10.4% had anti-Leptospira antibodies, followed by SISCAL (8%) and backyard animals (2.5%). The serovars found were Bratislava, Pomona, serovar, Canicola and Icterohaemorrhagiae. Higher percentage of properties with pigs raised outdoors (SISCAL) had tick infested animals (20%) than those raised in backyard (6.7%), while commercial farms had no infested pigs nor infested breeding place. In both SISCAL and backyard pig breeding properties ticks were observed at the breeding site environment. Tick infestations were detected in areas surrounding pig breeding site in all three husbandry suystems. Ticks found were all Amblyomma scultpum nymphs or adults with the exception of one of Amblyomma parvum adult. In relation to anti-rickettsia serology to five Rickettsia species, 55.2% of pigs from commercial farms reacted to al least one species, backyard pigs reacted to 89.7% and all pigs of SISCAL showed anti-rickettsia titers. Consecutive tick sampling (June 2014 to February 2016) in SISCAL FAZU in Uberaba, showed the establishment A. sculptum ticks maintained by domestic pigs. These observations demonstrate the ability the pigs to maintain populations of A. sculptum at a favorable environment and may indicate a new trend in environmental infestations by this species of tick. Exposure to Leptospira and Rickettsia demonstrated the potential pigs exposure and transmission of important diseases in public health.
