Arachidonic acid cyclooxygenase metabolites, thromboxane B2 (TXB2), prostaglandin E2 (PGE2) and 6-keto-prostaglandin F1 (6-keto-PGF1) were measured in horses where anaesthesia was maintained with halothane. Two horses suffering from postanaesthetic myositis were compared with four normal horses. TXB2 and PGE2 levels were higher in mixed venous blood drawn(More)
PURPOSE/OBJECTIVE To determine the prognostic factors for predicting outcome of patients with adenocarcinoma of the fallopian tube and to evaluate the impact of treatment modalities in managing this uncommon disease. MATERIALS AND METHODS A retrospective analysis of the tumor registries from 6 major medical centers from January 1, 1960 up to March 31,(More)
By using alpha-phenyl N-tert-butyl nitrone (PBN) as spin trap molecule and the electron paramagnetic resonance (EPR) technique, we obtained the first direct evidence of in vivo intervention of free radicals during an ischemia (50 minutes) reperfusion phenomenon in kidney of an intact rabbit. An EPR signal (triplet of doublets) characterized by coupling(More)
Impaired left ventricular (LV) filling is known to be a major determinant of non-obstructive hypertrophic cardiomyopathy (HCM). Seventeen patients with non-obstructive HCM (mean age 71 years) were investigated by Doppler echocardiography, before and after oral treatment with verapamil (mean daily doses: 335 mg). Diagnosis was based on clinical and(More)
The cardiovascular and respiratory parameters of eight laboratory beagles were measured before and after the simultaneous injection of medetomidine (40 micrograms/kg bw) and ketamine (5 mg/bg bw). This combination produced a significant alteration in cardiovascular function. The heart rate, the stroke volume and cardiac output decreased while the systemic(More)
In control rabbits, a renal ischemia of 60 min followed by 10 min of reperfusion resulted in an enhanced free radical production in cortical tissue, as assessed by a significant decrease of free glutathione (42%), protein-bound GSH (17%), and vitamin E (49%). In contrast, catalase or glutathione peroxidase activities were not affected by these experimental(More)
Measurements of muscular microcirculation in horses anaesthetised with halothane were performed by laser Doppler flowmetry. Variations of microcirculation in the compressed and uncompressed triceps brachii were measured when horses were positioned in dorsal recumbency after a prolonged period in lateral recumbency. A significant post ischaemic hyperaemia(More)
Muscular microcirculation was studied in seven halothane anaesthetised horses in lateral recumbency using a laser Doppler flowmeter. A significant difference between the dependent and the uppermost triceps brachii was recorded. In the dependent muscles, microflow at first decreased and then increased up to the starting value. In the uppermost muscles, a(More)
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.
Postischaemic reperfusion injury is often attributed to the generation of oxygenated free radicals which may subsequently promote lipid peroxidation in cell membranes. Electron paramagnetic resonance spectroscopy in association with the spin trap molecule alpha-phenyl-N-tert-butyl-nitrone allowed direct confirmation of lipid free radical production after(More)
