Ultrapurified bovine haemoglobin solutions such as Oxyglobin are rarely used in equine medicine due to their relatively high cost and concerns over their safety. Four foals and a mature horse were administered Oxyglobin as part of their treatment regime to good clinical effect, and no adverse clinical signs were noted. All 5 animals went on to make a full recovery from the various disease processes that necessitated treatment with blood and blood products. Oxyglobin appears to be a useful adjunctive treatment for acute, life‐threatening anaemia in the horse. 相似文献

The effects of severe experimental anaemia on red blood cell HCO3
– dehydrationin vitro were examined in rainbow trout,Oncorhynchus mykiss. After 5 days of anaemia (haematocrit=4.9±1.1%) induced by intraperitoneal injection of phenylhydrazine hydrochloride, fish displayed elevated arterial CO2 tensions (anaemic PaCO2=3.19±0.42 torrvs. control PaCO2=1.35±0.17 torr) and a significant acidosis (anaemic pHa=7.73±0.04vs. control pHa=7.99±0.04). However, after 15–20 days of anaemia (hct=6.6±0.8%) induced by blood withdrawal, the arterial CO2 tension was significantly lower than the control value, suggesting that physiological adjustments occurred within this time period to compensate for the lowered haematocrit. Compensation probably did not involve alterations in ventilation, which was unaffected by 5 days of anaemia (anaemic
;w=786±187 ml min–1 kg–1
vs. control
;w=945±175 min–1 kg–1), based on indirect Fick principle measurements.Potential adaptations to longer term anaemia at the level of the red blood cells were investigated using a radioisotopic HCO3
– dehydration assay. Owing to the difference in haematocrits, the HCO3
– dehydration rate for blood from anaemic fish was significantly lower than that for control fish following equilibration at the same CO2 tension. This difference was eliminated when HCO3
– dehydration rates were measured on blood samples adjusted to the same haematocrit, a result which implies that the intrinsic rate of CO2 excretion at the level of the red blood cell was not up-regulated during anaemia. The difference was also eliminated by equilibrating the blood samples with CO2 tensions appropriate for the group from which the sample was obtained,i.e., PCO2=1.4 torr for control samples and PCO2=3.2 torr for anaemic samples; each at the appropriate haematocrit. It is concluded that the elevated PaCO2 helps to reset CO2 excretion to the control level, but that some additional physiological adjustment occurs to lower the PaCO2 after 15–20 days of anaemia. 相似文献

A 2-month-old Thoroughbred filly was referred to Hagyard Equine Medical Institute for further evaluation of acute pyrexia and a suspected intra-abdominal abscess based on abdominal ultrasonography performed in the field. Initial examination revealed bilateral uveitis, polysynovitis, a large internal abdominal abscess and pneumonia. A transtracheal wash confirmed the presence of a multi-sensitive strain of Rhodococcus equi. Anaemia and thrombocytopenia were noted during hospitalisation. Results of a Coombs test were consistent with an immune-mediated haemolytic process. Recurrent pyrexia, abdominal discomfort and severe respiratory distress unresponsive to intensive medical support motivated euthanasia followed by necropsy after 30 days of treatment. Overall, six extra-pulmonary disorders were simultaneously diagnosed despite the lack of pulmonary pyogranulomas. 相似文献

Integrated multi‐trophic aquaculture (IMTA) is an alternative approach to mono‐culture aquaculture that reduces environmental impacts of commercial aquaculture systems by combining the cultivation of fed species with extractive species. Shellfish play a critical role in IMTA systems by filter‐feeding particulate‐bound organic nutrients. They may also increase or decrease disease risk on farms by serving as reservoirs or barriers for important finfish pathogens such as infectious salmon anaemia virus (ISAV). This study aimed to optimize culture and molecular assays in shellfish tissues and to determine the fate of ISAV in mussels, Mytilus edulis. To determine detection limits, qRT‐PCR and culture assays in both CHSE‐ and ASK cells were optimized in ISAV‐inoculated mussel tissue homogenates. Both qRT‐PCR and culture assays performed in ASK cells had comparable detection limits of 102.8 TCID50 mL?1. The ISAV RNA genome was consistently detected in digestive gland tissue of ISAV‐exposed mussels. Viable ISAV was not detected in mussel tissues by culture analysis in CHSE‐ and ASK cells. The fact that qRT‐PCR analysis resulted in positive cycle threshold (CT) values that corresponded to the detectable range of ISAV in ASK culture assays suggests that little to no viable ISAV particles are present in the mussel tissues. 相似文献

ObjectiveTo evaluate effects of repeated alfaxalone or propofol administration on haematological and serum biochemical variables in cats undergoing radiotherapy.Study designProspective, block-randomized, clinical trial.AnimalsA group of 39 client-owned cats.MethodsAfter butorphanol (0.2 mg kg–1) and midazolam (0.1 mg kg–1) sedation, cats were randomly assigned to receive either alfaxalone or propofol for induction of anaesthesia and sevoflurane maintenance. Cats were anaesthetized daily with the same induction agent for 10–12 days. Complete blood counts, reticulocytes, Heinz body score and serum biochemistry were performed before the first treatment (T1), at T6, T10 and 3 weeks after the final treatment (T21). Cumulative induction agent dose for each cat at each time point was evaluated for an effect on Heinz body score. Data are shown as mean ± standard deviation; p < 0.05.ResultsAt baseline there were no significant differences in signalment or blood variables between groups. A significant decrease in haematocrit of 2.3% ± 0.77 (p = 0.02) between T1-T6 and T1-T10 [mean 4.1% (± 0.78, p < 0.0001)] was detected, with a significant increase in haematocrit of 2.1% ± 0.80 (p = 0.046) between T6-T21 and 4.0% ± 0.8 (p < 0.001) between T10-T21. Heinz body score significantly increased by 1.86 ± 0.616 (p = 0.013) between T1-T10. In the propofol group, reticulocytes increased significantly between T1-T6 [mean 23,090 μL–1 ± 7670 (p = 0.02)] and T1-T10 [mean 27,440 μL–1 ± 7990 (p = 0.007)]. Mean cumulative dose at T10 was 19.65 mg kg–1 ± 5.3 and 43.4 mg kg–1 ± 14.4 for alfaxalone and propofol, respectively, with no significant effect on Heinz body formation at any time point.Conclusions and Clinical relevanceHaematocrit decreased in both groups with recovery after 3 weeks. Repeated alfaxalone and propofol administration was not associated with marked haematological or serum biochemistry changes. 相似文献

Adverse drug reactions to potentiated sulfonamide antimicrobial drug combinations have been reported in many species, including horses. This report describes the occurrence of pancytopenia in 2 horses, one subsequent to an immune mediated reaction and the other bone marrow aplasia following the administration of trimethoprim and sulfadimidine. These cases highlight the importance of judicious use of antimicrobial agents and describe adverse drug reactions in horses receiving potentiated sulfonamide antimicrobials. 相似文献
