[Circulatory and respiratory effects of ketamine in horses anesthetized with halothane].
Ketamine (0.3 mg/kg) administered intravenously to 12 halothane anesthetized horses caused a significant respiratory depression during ten minutes when respiration was spontaneous. Significant hemodynamic effects were not observed except for cardiac index. Clinical application was also discussed.

[Use of hormonal parameters of phospho-calcium metabolism as a means of discriminating bone and joint disorders in patients with renal insufficiency].
Serum carboxyterminal parathyroid hormone (PTH) concentration (homologous measurement of the 53-84 fragment and heterologous bovine measurement) has been measured and correlated with both clinical and radiological findings of secondary hyperparathyroidism (HPT), studied quantitatively according to a score published in literature, in 95 patients with chronic renal failure on maintenance hemodialysis. Mean serum PTH concentration (53.84) is statistically higher in patients with severe clinical and radiological evaluation of HPT than in patients with moderate or slight manifestations of HPT (M +/- DS: 515.8 +/- 243.7 pg/ml VS 271.3 +/- 166.1 pg/ml p less than 0.001). However, even with high serum concentration, serum PTH level does not allow to predict HPT severity, suggesting a retention of PTH fragments in serum without biologic activity probably.

Evaluation of the arterial blood pressure of dogs by two noninvasive methods.
The determination of the arterial blood pressure was done on 12 healthy mixed breed dogs in both the anesthetized and the conscious state, to evaluate two instruments (Doppler flow detector and infrasonde D4000), in their ability to indirectly determine arterial blood pressure. The coefficients of variation were higher with indirect methods when compared with the results obtained by cannulation. These coefficients were lower with the Doppler flow detector. The correlation study showed that both apparatuses were reliable in most situations. The infrasonde D4000 was more accurate than the Doppler in the conscious animals. However the results showed a lack of precision in hypertensive conscious dogs. The diastolic arterial blood pressure was particularly precise in the case of the anesthetized hypotensive dogs. Its sensitivity allowed it to register muscle movement artifacts. The Doppler flow detector showed less variation and was particularly accurate in both anesthetized and conscious hypertensive dogs. Its sensitivity allowed artifact movement sounds to be detected. The Doppler should be used in quiet surroundings or earphones should be worn by the evaluator. Some form of restraint is needed with the use of both instruments. Even if the correlations with the direct arterial blood pressure values were better with the infrasonde D4000, greater variations were found in the individual readings. The Doppler instrument represents in the hands of the investigators a better instrument for routine monitoring of blood pressure in the dog.
