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)
This preliminary study demonstrated the existence of a free radical generation during an experimental postischemic muscular reperfusion in a halothane anesthetized horse. The authors used alpha-phényl-N-tert-butylnitrone as a spin trap agent and the electronic paramagnetic resonance method to observe in vivo a free radical generation.
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)
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)
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)
The authors report 2 clinical cases of ventricular aneurysm associated with a false tendon attached to the neck of the aneurysm. The first patient had no signs of false tendon before myocardial infarction. When the aneurysm developed, a false tendon was observed at its neck; a second false tendon attached to the first was also seen and appeared to have… (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)
