FCE dog

K A Bartholomew, K E Stover, N J Olby, S A Moore
Fibrocartilaginous embolic myelopathy (FCE) is common in dogs; however, there is conflicting information in the veterinary literature regarding clinical characteristics and data on recovery in severe cases is sparse. A systematic review of canine FCE was performed to delineate the natural history of this disease. 322 previously reported cases and 71 previously unreported cases were identified for inclusion. Source publications were identified via PubMed central search and by references from review articles...

This study investigated the cross sectional area (CSA) and fat infiltration of the epaxial muscles in Dachshunds with compressive spinal cord lesions due to intervertebral disc herniation (IVDH) and in dogs with non-compressive spinal cord lesions with fibrocartilaginous embolism (FCE). The CSA and fat infiltration of the multifidi and longissimus dorsi muscles were determined from T1 weighted magnetic resonance images. Difference in CSA and fat infiltration between the lesion- and non-lesion side in the Dachshunds was assessed using mixed model analysis...

The flanker task developed by B. A. Eriksen and C. W. Eriksen (1974) is a reliable method of showing the effect of flanking stimuli (flankers) on responses to central targets. When flankers map to the same or different responses as the targets, response latencies reduce or increase, respectively, relative to neutral flankers. In Experiment 1, the authors present 2-dimensional line drawings of structurally distinct animals: 2 birds, 2 bugs, and 2 dogs. These pairs generated a reliable flanker compatibility effect (FCE) for both upright and inverted flankers...

Fibrocartilaginous embolism (FCE) is a disorder of acute onset that presents with nonprogressive ataxia. We performed a retrospective examination of FCE of the spinal cord diagnosed by characteristic clinical findings and magnetic resonance imaging (MRI) in 26 dogs. In the present study, treatment consisting of physiotherapy alone, or this in combination with corticosteroid administration, was initiated immediately following diagnosis of FCE. Age at onset and the gender ratio in the present study closely correlated with those previously reported...

Fibrocartilaginous embolism (FCE), a disorder of rapid onset featured by nonprogressive paralysis and paresis of four legs, shows clinical symptoms very similar to those of other disorders, e.g., disk herniation. We examined 10 animals diagnosed with FCE based on clinical symptoms and magnetic resonance imaging (MRI) findings in a retrospective study to examine the relationship between onset-to-diagnosis/treatment initiation time and prognosis of FCE. Statistical procedures, including Fisher's exact probability test, were conducted...

Fibrocartilaginous embolization (FCE) of the spinal cord is a common disease in large breed dogs. There are only a few reports about this entity in small breed dogs and it has never been reported in chondrodystrophic breed. For definitive diagnosis histopathologic examination is necessary. Magnetic resonance imaging (MRI) as a potential diagnostic tool for intravitam diagnosis of FCE has been mentioned before, but results have not been reported so far. This report describes the neurological findings and MRI results in three small breed dogs, including a Pekingese dog, with FCE of the spinal cord...

Safety studies done with neotame, a sweetener with intense taste, demonstrate that changes in bodyweight (BW) and BW gain (BWG) are due to reduced food consumption (FC) rather than toxicity. When offered a choice, rats preferred basal diet to diet with relatively low concentrations of neotame. When no choice was available, rats ate less as concentrations increased, demonstrating reduced palatability. Changes in dietary concentrations of neotame resulted in changes in FC. The maximum tolerable doses (MTDs) in rats, dogs, and mice were due to decreases in BWG secondary to poor palatability of diets when neotame concentrations exceeded approximately 35,000 ppm...

This study describes the occurrence of fibrocartilaginous embolism of the spinal cord (FCE) in eight juvenile Irish Wolfhounds that were presented within a period of 16 months (1996-1997). The dogs, seven males and one female between eight and 13 weeks of age, were presented because of an acute onset of abnormal locomotion. Five dogs were euthanized and FCE was diagnosed by the histomorphological presence of focal myelomalacia and Alcian blue-positive-nucleus-pulposus material in the spinal cord vasculature...

We conducted a clinical evaluation of FCE 23762, a methoxymorpholino analog of doxorubicin, in 48 dogs with metastatic, nonresectable, or chemotherapy-resistant spontaneous malignancies at an initial dosage of 50-60 microg/kg IV every 3 weeks. Clinical evidence of toxicity was minimal; 6 dogs developed grades I, II, and III hematologic toxicities after the 1st treatment, and 1 dog developed grade II gastrointestinal toxicity. One dog became pancytopenic 4 months after discontinuation of FCE 23762. No other adverse effects were noted...

Clinical features of 36 dogs with histologically confirmed fibrocartilaginous embolism (FCE) were contrasted with those of 26 dogs in which FCE was suspected based on characteristic clinical findings and the absence of compressive spinal cord disease on myelography. Dogs with confirmed and suspected FCE were of similar signalment, and had acute, nonprogressive dysfunction, often associated with trauma or exercise. The "suspected" group included fewer giant breeds and more often had asymmetric lesions, intact nociception, and upper motor neuron involvement...

A series of derivatives of 4-phenyl-1,4-dihydropyridine bearing imidazol-1-yl or pyridin-3-yl moieties on the phenyl ring were synthesized with the aim of combining Ca2+ antagonism and thromboxane A2 (TxA2) synthase inhibition in the same molecule. Some of these compounds showed significant combined Ca2+ antagonism and TxA2 synthase inhibition in vitro, while others showed only one single activity. Structural requirements for significant single or combined activities are discussed. Theoretical conformational analysis, by molecular mechanics and semiempirical AM1 calculations, was performed for 1,4-dihydro-2,6-dimethyl-4-[3-(1H-imidazol-1-yl)phenyl]- 3,5-pyridinedicarboxylic acid, diethyl ester (FCE 24265) and two close congeners...

The combination of thromboxane (TX) synthase inhibition and prostaglandin (PG) H2/TXA2 receptor antagonism yields enhanced antithrombotic effects as compared with either intervention alone. However, it is not known whether the enhancing effect of TX synthase inhibition is expressed also in the presence of complete blockade of PGH2/TXA2 receptors. Thus we evaluated the antithrombotic effects of increasing doses of the PGH2/TXA2 receptor antagonist L 670596 alone and in combination with a dose of the TX synthase inhibitor FCE 22178 causing > 95% inhibition of platelet TXB2 production...

A sensitive and selective high-performance liquid chromatographic method for the determination of FCE 24928 (4-amino-androsta-1,4,6-triene-3,17-dione) in human plasma is reported. The drug was extracted from buffered (pH = 8) plasma samples with methylene chloride-isooctane, then analysed by reversed-phase liquid chromatography. Quantitation was achieved by ultraviolet detection of the eluate at 238 nm. Blank plasma samples from humans, dog and rat assayed as described showed no significant peak at the retention time of the compound of interest...

Turosteride was tested in a series of studies for its effect on 5 alpha-reductase and for its possible influence on other steroidogenic enzymes and on steroid receptors. The compound was found to inhibit human and rat prostatic 5 alpha-reductases with IC50 values of 55 and 53 nM, respectively, whereas it caused a less marked inhibition of the dog enzyme (IC50 2.2 microM). Turosteride showed no relevant effect on rat adrenal C20,22-desmolase (IC50 254 microM) and human placental aromatase (IC50 > 100 microM), and only at relatively high concentrations it caused inhibition of human placental 5-ene-3 beta-hydroxysteroid dehydrogenase-isomerase (3 beta-HSD-I) (IC50 2...

The literature supports the hypothesis that the association of a thromboxane (TX)A2 synthase inhibitor and a PGH2/TXA2 receptor antagonist has a superior antithrombotic effect when compared to both aspirin and single agent alone; a compound endowed with the dual mechanism of action might therefore be of therapeutic value for the management of thrombotic disorders. FCE 27262, an imidazol-1-yl-ethylideneaminooxypentanoic acid, displaces in vitro the binding of [3H]SQ 29,548 to washed human platelets (IC50 = 6...

Perfluorocarbon emulsion (FCE) particles are reported to be taken up by the reticuloendothelial system (RES) and ultimately eliminated by the lung. This distribution provides an opportunity to measure oxygen partial pressure in vivo with fluorine-19 magnetic resonance imaging (19F MRI). Since the MR image signal-to-noise ratio is directly proportional to the fluorine concentration in the tissue, a greater concentration of perfluorocarbon (PFC) in the tissue will result in a greater confidence in the oxygen image and reduce measurement time...

BACKGROUND: Tallimustine, a benzoyl nitrogen mustard derivative of the antiviral agent distamycin A, is a new alkylating agent which binds to A-T rich regions of DNA in the minor groove producing highly sequence-specific alkylations. Its main preclinical features are a significant antitumor activity in animal models and a lack of cross-resistance in vitro and in vivo with L-PAM. Myelotoxicity was dose-limiting in animals, with a more than 100-fold difference in bone marrow sensitivity between mice and dogs...

FCE 22250 (3-(N-piperidinomethylazino)methylrifamycin SV) is a member of the new class of 3-azinomethylrifamycins characterized by a long persistance in animals, a good oral absorption and a broad antibacterial spectrum including mycobacteria. In the experimental mice infection sustained by Mycobacterium tuberculosis H37Rv, FCE 22250 shows an efficacy 14 times higher than rifampicin and is still therapeutic when administered once every three weeks.

FCE 22509, 5-(Z,E)-13,14-didehydro-20-methyl-carboprostacyclin, a chemically stable prostacyclin (PGI2) derivative, was 3.5 times more potent than PGI2 in relaxing bovine coronary artery in vitro; unlike PGI2, it did not contract bovine coronary vein and it antagonized PGI2-induced contractions of the coronary vein. In vitro smooth muscle (guinea pig ileum and trachea and rat stomach strip) was contracted to a lesser extent than with PGI2. FCE 22509 was about five times less potent than PGI2 in deaggregating platelet clumps formed on rabbit Achilles tendon bathed with heparinized cat blood (ED50 = 7...
