The purpose of this study was to determine the effect of regulating factors on the oxygen equilibrium curve (OEC) under standard conditions and then to calculate the oxygen extraction between arterial and jugular venous blood in healthy Standardbred horses. The results were compared to those previously obtained in humans and cattle, using the same experimental method. The partial oxygen pressure at 50% saturation of haemoglobin, measured under standard conditions (standard P50), was 24.8 +/- 2.0 (SD of mean) mm Hg. This value was similar to the cattle standard P50 (25.0 +/- 1.4 mm Hg, SD of mean) but lower than the human standard P50 (26.6 +/- 1.2 mmHg, SD of mean) previously reported using the same experimental method. The effects of regulating factors on the standard OEC were also determined, and a major effect of pH and temperature was noted. In contrast, partial carbon dioxide pressure played only a minor role in horses, compared to cattle and humans. No significant correlation was found between phosphate and chloride concentrations and standard P50. (c) 2004 Elsevier Ltd. All rights reserved. [less ▲]

The purpose of this retrospective study was to further identify in the equine species the clinical signs and blood parameters that could be useful to identify a hepatic disease and act as predictors of the outcome in animals suffering from an acute hepatic insufficiency. The study included 31 equids that were hospitalized at the University of Liege and that suffered from a hepatic (group 1, 17 cases of hepatitis; group 2, 11 cases of hyperlipemia) or post-hepatic (group 3, 3 cases of cholelithiasis) disease. Frequency of the clinical signs and values of selected blood parameters on admission were compared statistically between surviving and non-surviving animals. The most frequently presented clinical signs were depression, decreased appetite or anorexia, fever, tachycardia, polypnea, icterus, and congested mucous membranes. Frequency of the clinical signs and blood parameter values were not statistically different in surviving and non-surviving animals, with the exception of gamma-glutamyl transferase (GGT) and alkaline phosphatase (ALP), which were significantly higher in animals with fatal outcome, with a cutoff value of 224 and 820 IU/L, respectively.

Two studies were conducted in order to assess the linearity and stationarity of the pharmacokinetics of tiludronate in horses. For each study, plasma concentrations of tiludronate were measured by HPLC-UV at regular intervals and noncompartmental analysis was performed. First, single intravenous administrations of 0.05 (group 1, n = 5), 0.1 (group 2, n = 5) and 0.2 mg/kg (group 3, n = 5) were performed in healthy male adult horses. A linear relationship between groups was found for C5min (C5min = 0.0726 + 11.8589 * dose) as well as for AUC0-inf (AUC0-inf = -0.632561 + 30.9649 * dose). Clearance ranged from 0.033 to 0.044 L/h/kg and was not significantly different between groups. MRT (h) were 3.96, 4.95 and 9.40 and VDss (L/kg) were 0.16, 0.19 and 0.28 for the 0.05, 0.1 and 0.2 mg/kg doses respectively. Second, 10 daily intravenous administrations at a dosage rate of 0.1 mg/kg were administered to 4 healthy horses. Plasma tiludronate concentrations were measured after the 1st and 10th dose as well as 8 hours after each dose. The mean plasma accumulation ratio between the 1st and the 10th dose was 1.31 ± 0.48. Medians of the tiludronate concentration values measured in plasma 8 hours post-dose were not statistically different between doses. Maximum and minimum concentrations of tiludronate (mg/L) following the last dose were 0.91 and 0.04 respectively. It was concluded that the pharmacokinetics of tiludronate in horses are linear from 0.05 to 0.2 mg/kg IV and stationary after 10 IV administrations of 0.1 mg/kg. [less ▲]

Atypical myopathy (AM), also called “atypical myoglobinuria”, is a frequently and rapidly fatal myopathy of unknown origin occurring sporadically in grazing horses. As opposed to the exertional rhabdomyolysis syndrome (ERS), clinical signs of AM are not induced by exercise. The condition has been reported in several European countries including Belgium, France, Germany and Great Britain. Clinical signs of AM are characterised by muscular weakness, stiffness, recumbency, sweating and when urine is observed, myoglobinuria. These signs are characteristic but not pathognomonic of the disease; the differential diagnosis of sudden weakness, severe myopathy and/or unexpected death includes several neurogenic and myopathic disorders. The main pathologies that share clinical similarities with AM include the acute form of grass sickness (GS), acute piroplasmosis, botulism, ERS, the hyperkalemic periodic paresis (HPP), nutritional myopathy (NM; i.e. vitamin E and/or selenium deficiency), plants or drugs (i.e. ionophores intoxication) intoxication, tetanus and postanaesthesia myopathy. This report aims at reviewing key facts in history, clinical signs, clinical examination and laboratory findings that contribute towards the diagnosis of AM and/or invalidate the diagnosis of other pathologies.

The purpose of this study was to validate an equine-specific osteocalcin (OC) radioimmunoassay (RIA) for use in donkeys and to establish age-related changes in serum OC concentrations in healthy donkeys. Serial dilutions of donkey serum showed parallelism with standard curves obtained with the equine-specific OC RIA. There was a tight linear regression between donkey serum OC values obtained with the equine specific OC RIA and a commercially available bovine-specific OC RIA. Serum OC levels of 27 healthy donkeys, analysed with the equine-specific OC RIA, showed a tight negative logarithmic regression with age. Least square means and standard error of serum OC values were 67 +/- 10 mug/l in 0.6-4-year-old donkeys (group 1), 32 +/- 9 mug/l in 5-9-year-old donkeys (group 2) and 15 +/- 11 mug/l in >9-year-old donkeys (group 3). Serum OC values were significantly (p < 0.01) higher in group 1 than in groups 2 and 3. The equine-specific OC RIA may be a useful and practical tool to assess bone metabolism and skeletal diseases in donkeys. [less ▲]
