Parâmetros métricos da traqueia e suas correlações com o perímetro torácico, peso e comprimento corporal de cães sem raça definida (Canis familiaris, Linnaeus, 1758)

The present study aimed to analyze metric data from the trachea of dogs and to correlate them with the thoracic girth, body length and weight. We used 48 dogs of unknown breed, 19 males and 29 females. The animals were weighed and then body length, thoracic girth, length and diameter of the trachea, and the number of tracheal rings were measured. The weight of dogs ranged from 4.2 to 21.5 kg, body length from 40.6 to 81.0 cm and thoracic girth from 36.0 to 63.5 cm. The trachea exhibited a total number of tracheal rings between 32 and 43, length between 13.0 and 23.4 cm, diameter of the cervical portion between 11.0 and 23.5 mm and in the thoracic portion between 8.2 and 20.9 mm. We also evaluated the tracheal termination skeletopy, which maintained relations with the 2nd (2.0%), 3 (6.3%), 4 (20.8%) or 5 (12.5%) intercostal spaces, and with the 3rd (6.3%), 4th (35.4%) or 5th (16.7%) ribs. Strong positive correlations of tracheal length with body weight (rS = 0.756, p <0.001), body length (r = 0.808, p <0.001) and thoracic girth (r = 0.735, p <0.001) were found. Therefore, the anatomical study of the trachea provides morphological subsidies for the realization of clinical and surgical procedures in this organ, being an important tool in veterinary practice.

POST-MORTEM LESIONS of UROLITHIASIS IN A LESSER SEED FINCH (Sporophila angolensis).

Urolithiasis is a disease that despite being a commonly observed problem in veterinary practice is uncommon in birds. Such disease was not reported in passeriforms to date. Accordingly, the aim of the present article is to describe a case of urolithiasis in an adult female lesser seed finch (Sporophila angolensis) pet bird which presented abdominal distension, respiratory distress, and apathy prior to death. The bird had history of being fed with a diet rich in protein. After the bird death, a necropsy was conducted in order to determine the cause of death. At necropsy, accentuated ascites, hydropericardium, and ureteral stones in the left ureter could be grossly observed. Additional tests related with viral and bacterial microbiological testing and with the determination of calculi composition could not be performed since the owner did not consent with the procedures because of the cost. Since the bird was fed on a high protein diet, a relationship between the ureteroliths and dietary imbalance was suggested with participation of protein in calculi development by providing the organic nuclei. Additionally, we conclude that the presence of calculi in the ureter resulted in urinary flow blockage, ascites, and consequent acute respiratory failure due to filling of air sacs with liquid.

Hemodynamic evaluation of the right portal vein in healthy dogs of different body weights

Background: Doppler ultrasonography is an important tool for evaluating hepatic portal hemodynamics. However, no study in dogs of different body weights, in the range encountered in routine clinical veterinary practice, has been reported. It can be difficult to obtain an ideal insonation angle when evaluating the main portal vein, so evaluation of the right portal vein branch has been described in humans as an alternative. The aim of this study was to analyze, through Doppler ultrasonography, the hemodynamics in the right portal vein branch in dogs of different body weights.Methods: Thirty normal dogs were divided in three groups by weight, in order to establish normal values for mean velocity, flow volume and portal congestion index of the right portal vein branch by means of Doppler ultrasonography.Results: In all dogs ideal insonation angles were obtained for the right portal vein branch. The average velocity was similar in the three groups, but the portal congestion index and the flow volume differed, showing that the weight of the dog can influence these values.Conclusion: Doppler ultrasonography for the evaluation of flow in the right branch of the portal vein could be a viable alternative, or complement, to examining the main vessel segment. This is especially so in those animals in which an ideal insonation angle for examination of the main portal vein is hard to obtain. In addition, the weight of the dog must be considered for the correct evaluation of the portal system hemodynamics, particularly for portal blood flow and the congestion index.

Atividade colinesterásica cerebral e comportamento de ratos após exposição perinatal ao diclorvós

O organofosforado diclorvós impregnado em coleiras plásticas é um recurso utilizado em medicina veterinária que visa ao controle de ectoparasitas de cães e gatos. O objetivo deste trabalho foi avaliar os efeitos do uso de coleiras plásticas impregnadas com diclorvós (8,37%) em ratas Wistar durante o período de gestação e lactação, como possível fonte de alterações comportamentais e da atividade colinesterásica cerebral dos filhotes. Na desmama, não houve diferença na atividade colinesterásica cerebral entre as mães tratadas com diclorvós e o grupo controle, bem como entre os respectivos filhotes. O tratamento com diclorvós também não influenciou no comportamento geral dos animais, avaliado no campo aberto, nem no nível de ansiedade testado no labirinto em cruz elevado, ambos aos 35 dias pós-natal.

ANTINOCICEPTIVE EFFECT OF AMITRAZ IN MICE AND RATS

Amitraz, a formamidine insecticide and acaricide used in veterinary practice, presents side effects related to its pharmacological activity on az-adrenergic receptors. The present study was undertaken to investigate the antinociceptive effect of amitraz in rats and mice. The tail-flick test was used to determine the duration of the antinociceptive effect of the intraperitoneal tip) administration of amitraz (1 and 2 mg/kg, 10 animals per group) in male Wistar rats weighing 180-220 g. The writhing test (using 10 ml/kg of a 0.6% acetic acid solution as a painful stimulus). was performed in 140 male Swiss mice weighing 20-30 g, divided into 14 groups that received ip injections of saline, amitraz (0.5, 1.0, 1.5, 2.0 and 4.0 mg/kg), xylazine or detomidine (1.0, 1.5, 2.0 and 4.0 mg/ kg), in order to compare the effect of amitraz to that caused by xylazine and detomidine, and to investigate the participation of alpha(2)-adrenergic receptors which were blocked by idazoxan (1 mg/kg). Amitraz induced a significant antinociceptive effect in both rats and mice. This effect is blocked in mice by idazoxan.

Efeitos cardiorrespiratórios da metadona, pelas vias intramuscular e intravenosa, em cadelas submetidas à ovariossalpingo-histerectomia

Methadone is a little used opioid in veterinary practice, and there are still questions about its use. The objective of this study was to evaluate the effects of intramuscular (IM) or intravenous (IV) administration of methadone on cardiopulmonary parameters and times of extubation and recovery in female dogs submitted to ovariohysterectomy. Sixteen adult female dogs were used and premedicated with levomepromazine (0.6mg/kg, IM). After 20 minutes, propofol (5mg/kg, IV) was used for induction and anesthesia was maintained with isoflurane. After 10 minutes, methadone at 0.3mg/kg was administered intravenously in IVG and intramuscularly in IMG. The measurement of heart (HR) and respiratory rates (RR), median arterial pressure (MAP), esophagic temperature (ET) and concentration of end-tidal carbon dioxide (PE'CO2) was performed immediately before the administration of the opioid (T0), after 20 minutes (T1) and then at 10-minute intervals (T2, T3, T4 and T5). The statistical analysis used was profile (5%). HR, APM, RR, PE'CO2, BT and SpO2 did not differ significantly among times or between groups at any time. Times of extubation and recovery were higher in IVG. It is possible to conclude that IV and IM administration of methadone did not produce changes in the cardiorespiratory parameters of that specie.
