摘要:

ABSTRACTSamples for microbiological culture were collected from the uterus of bitches using transcervical uterine cannulation (31 samples, 23 bitches) and from the uterus, cervix and vagina post mortem (19 bitches) at all stages of the reproductive cycle. Samples were cultured for aerobic and anaerobic bacteria and for aerobic mycoplasmas. Bacteria were always found in the uterus during prooestrus and oestrus (12 positive in 12 cultures) and rarely at other stages of the reproductive cycle: during anoestrus (one in 14) and other stages (none in 24). When microorganisms were detected at three sites post mortem, those found in the cervix and vagina were always of the same species as those found in the uterus. In six out of 13 instances, microorganisms were found in the cervix or vagina when none were found in the uterus. The mean number of isolates, number of bacteria seen in uterine cytology and bacterial growth were greater (P<0–005) during oestrus and pro‐oestrus than at other stages. Bacteria isolated from the uterus, in order of frequency, wereEscherichia coli, Haemophilusspecies, α‐haemo‐lytic streptococci,Corynebacteriumspecies,Streptococcus canis, Alcaligenes faecalis, Bac‐teroidesspecies,Pasteurellaspecies andProteus mirabilis.No mycoplasmas were cultured from the samples. This study indicates that the uterus of the normal bitch has a uterine microflora during pro‐oestrus and oestrus that is similar to that of the vagin

摘要:

ABSTRACTFive dogs presented with varying degrees of subconjunctival swelling and enophthalmos. Biopsy revealed the subconjunctival tissue to be fat. Surgical excision in two cases resulted in resolution of the clinical signs and demonstrated that the fat came from the retrobulbar region.

摘要:

ABSTRACTFructosamines are glycated serum proteins that reflect long‐term serum glucose concentrations in humans and several animal species. In the present study, blood samples were drawn from three populations of diabetic cats: untreated diabetic cats with clinical symptoms prevailing only a few days (n = 1), untreated diabetic cats with symptoms lasting more than two weeks (n = 6) and clinically well stabilised diabetic cats receiving insulin twice daily which showed no signs of disease (n = 4). All untreated diabetic cats showed elevated fructosamine measurements. Based on fructosamine measurements, clinically well stabilised diabetic cats could be subdivided further according to the degree of glycaemic control. Diabetic cats with satisfactory glycaemic control revealed fructosamine concentrations within or close to the reference range (146 to 271 umol/litre), whereas fructosamine concentrations above 400 umol/litre indicated insufficient glycaemic control. This study suggests that the fructosamine assay reflects persistently elevated serum glucose concentrations in cats and is a useful parameter for diagnosing and monitoring diabetes mellitus in cat

摘要:

ABSTRACTHeart rate variability was measured in 81 Cavalier King Charles spaniels to investigate if it could be used to evaluate the severity of mitral regurgitation and to predict decompensation. Heart rate variability was assessed by the natural logarithm of the variance of the R‐R intervals for 20 consecutive beats obtained from electrocardiographic recordings. Twenty‐two of the dogs were clinically normal and 59 had mitral regurgitation caused by chronic valvular disease. The severity of mitral regurgitation was evaluated by echocardiography and thoracic radiography. Heart rate variability was found to be reduced (P<0.001) among dogs with severe left atrial and ventricular dilatation and clinical signs of congestion. No significant differences in heart rate variability were found among normal dogs, dogs with only cardiac murmur, and dogs with echocardiographic evidence of slight to moderate left atrial and ventricular dilatation. Overall, an association was found between heart rate variability and left atrial to aortic root ratio and left ventricular end diastolic diameters (r = 0.72 and 0.64, respectively, P<0.001), as well as heart and respiratory rate (r = 0.80 and 0.69, respectively, P<0.001). Multiregression analysis showed that, in order of importance, heart rate, left atrial diameter and respiratory rate had significant effects on heart rate variability. Among these parameters, heart rate variability and left atrial diameter were found to be most efficient in separating decompensated dogs from compensated. It is concluded that heart rate variability may provide the clinician with valuable information when assessing the severity of mitral regurgitation caused by chronic valvular dise

摘要:

ABSTRACTThe effects of premedication with four different intravenous doses of romifidine (20, 40, 80 and 120 (μg/kg body weight) and a saline placebo were compared in a group of 20 adult beagles of both sexes, undergoing anaesthesia with propofol for a clinical dental procedure. Anaesthesia was induced 10 minutes after premedication and maintained by intravenous infusion of propofol for a period of 30 minutes. Romifidine had a marked synergistic effect with propofol and reduced the required induction and infusion doses by more than 60 per cent for a standard level of anaesthesia; the synergistic effect was dose related. Following premedication, propofol produced no significant alteration of respiratory rate, heart rate or rectal temperature. Anaesthesia was found to be more stable following romifidine premedication at all doses studied. The quality of induction was unaltered by the dose of the romifidine. Recovery from anaesthesia was smooth and of a similar quality in all cases. There were no differences in the recovery times between the unpremedicated group and the dogs premedicated with any dose of romifidine studied. There were no adverse effects noted following this anaesthetic regimen. The marked dose‐related synergism with propofol induction and infusion anaesthesia is relevant should romifidine be used in the dog in clinical veterinary practi
