Trazodone-gabapentin association increases sedation scores with mild hemodynamic and echocardiographic impact in healthy cats.

Despite the increasing use of drugs to facilitate feline management in veterinary care, there is still a lack of information on the anxiolytic and sedative effects and their specific physiological impacts. We aimed to compare the sedative, hematological, biochemical and cardiovascular effects of oral single-dose trazodone and gabapentin, alone or in combination, in 8 healthy adult mixed-breed domestic cats on a prospective, randomized, cross-over, and placebo-controlled study. Cats were assigned to receive an oral single dose of trazodone (50 mg) (TG), gabapentin (100 mg) (GG), trazodone (50 mg) and gabapentin (100 mg) (GTG), or placebo (PG).

Ophthalmic effects of dexmedetomidine, methadone and dexmedetomidine-methadone in healthy cats and their reversal with atipamezole.

Objectives: The aims of this study were to evaluate and compare the effects that dexmedetomidine and methadone, either alone or in combination, have on the ocular variables of healthy adult cats when administered intramuscularly, as well as their reversal with atipamezole.

Methods: A randomized crossover blinded study of 10 healthy cats was used to assess the effect of 0.2 mg/kg methadone (MET), 7.

Progressive cutaneous angiomatosis in the metatarsal region of a cat.

Case Description: A 1.5-year-old 4.0-kg (8.

Association of riluzole and dantrolene improves significant recovery after acute spinal cord injury in rats.

Background Context: Damage to the spinal cord can result in irreversible impairment or complete loss of motor, sensory, and autonomic functions. Riluzole and dantrolene have been shown to provide neuroprotection by reducing neuronal apoptosis after brain and spinal cord injury (SCI) in several animal models of neurologic disorders. As these drugs protect the injured spinal cord through different mechanisms, we investigated the cumulative effects of riluzole and dantrolene.

Anesthetic synergy between two n-alkanes.

Objective: N-butane and n-pentane can both produce general anesthesia. Both compounds potentiate γ-aminobutyric acid type A (GABA) receptor function, but only butane inhibits N-methyl-d-aspartate (NMDA) receptors. It was hypothesized that butane and pentane would exhibit anesthetic synergy due to their different actions on ligand-gated ion channels.

Ischemia-reperfusion model in rat spinal cord: cell viability and apoptosis signaling study.

This work aimed at determining the ideal ischemia time in an in vitro ischemia-reperfusion model of spinal cord injury. Rat spinal cord slices were prepared and then exposed or not to oxygen deprivation and low glucose (ODLG) for 30, 45, 60, 75 and 90 minutes. Cell viability was assessed by triphenyltetrazolium (TTC), lactate dehydrogenase (LDH) release, and fluorochrome dyes specific for cell dead (ethidium homodimer) using the apotome system.

Effects of methylprednisolone, dantrolene, and their combination on experimental spinal cord injury.

This study aimed to evaluate the effect of methylprednisolone sodium succinate, dantrolene sodium, and their combination on experimental spinal cord injury. We used 25 rats (Rattus norvegicus) that were divided into five groups. The negative control group (NC) consisted of animals without spinal cord trauma.

Omega-conotoxin MVIIC attenuates neuronal apoptosis in vitro and improves significant recovery after spinal cord injury in vivo in rats.

Excessive accumulation of intracellular calcium is the most critical step after spinal cord injury (SCI). Reducing the calcium influx should result in a better recovery from SCI. Calcium channel blockers have been shown a great potential in reducing brain and spinal cord injury.

Systemic effects induced by intralesional injection of ω-conotoxin MVIIC after spinal cord injury in rats.

Background: Calcium channel blockers such as conotoxins have shown a great potential to reduce brain and spinal cord injury. MVIIC neuroprotective effects analyzed in in vitro models of brain and spinal cord ischemia suggest a potential role of this toxin in preventing injury after spinal cord trauma. However, previous clinical studies with MVIIC demonstrated that clinical side effects might limit the usefulness of this drug and there is no research on its systemic effects.

Head trauma as a possible cause of central diabetes insipidus in a cat.

A 13-month-old female domestic shorthair cat presented with a 10-month history of polyuria and polydipsia that began after having been hit by a car. Neurological examination revealed visual deficits and an absent bilateral menace response. Hematological and serum biochemical analyses were within reference values, but hyposthenuria was identified.

Solubility of haloether anesthetics in human and animal blood.

Background: Anesthetic blood solubility predicts pharmacokinetics for inhaled agents and is essential for determination of blood anesthetic concentrations from end-tidal gas concentrations using Henry's Law. Though used to model anesthetic effects in humans, there are limited interspecies solubility comparisons that include modern haloethers. This study aimed to measure hematocrit-adjusted blood:gas anesthetic partition coefficients (λ B:G) for desflurane, sevoflurane, isoflurane, and methoxyflurane in humans and animals.

Endoscopic transcervical intrauterine artificial insemination in Labrador Retriever bitches.

Besides post-thawing reduced semen quality, there are some difficulties in the execution of the endoscopic transcervical intrauterine artificial insemination (AI) with frozen-thawed semen in bitches. Therefore, the aims of the present study were to evaluate behavioral and reproductive parameters (i.e.

Cardiorespiratory and blood gas alterations during laparoscopic surgery for intra-uterine artificial insemination in dogs.

Cardiorespiratory and blood gas alterations were evaluated in 6 healthy dogs that underwent a laparoscopic procedure using isoflurane anesthesia and carbon dioxide (CO(2)) pneumoperitoneum for 30 min. Heart rate, respiratory rate, body temperature, venous blood pH, partial pressure of CO(2) and oxygen, oxygen saturation, total carbon dioxide (TCO(2)) and bicarbonate were monitored. Significant alterations were hypercapnia, hypoventilation, and respiratory acidosis.

Effects of dantrolene on apoptosis and immunohistochemical expression of NeuN in the spinal cord after traumatic injury in rats.

Dantrolene has been shown to be neuroprotective by reducing neuronal apoptosis after brain injury in several animal models of neurological disorders. In this study, we investigated the effects of dantrolene on experimental spinal cord injury (SCI). Forty-six male Wistar rats were laminectomized at T13 and divided in six groups: GI (n = 7) underwent SCI with placebo and was euthanized after 32 h; GII (n = 7) underwent laminectomy alone with placebo and was euthanized after 32 h; GIII (n = 8) underwent SCI with dantrolene and was euthanized after 32 h; GIV (n = 8) underwent SCI with placebo and was euthanized after 8 days; GV (n = 8) underwent laminectomy alone with placebo and was euthanized after 8 days; and GVI (n = 8) underwent SCI with dantrolene and was euthanized after 8 days.

Idiopathic hypertrophic osteopathy in a cat.

This report describes the first case of idiopathic hypertrophic osteopathy (HO) in a cat. No causes for the bone pathology were found following evaluation of the physical and laboratory examinations (complete blood count, albumin, creatinine, urea, alkaline phosphatase, alanine aminotransferase, aspartate aminotransferase and gamma-glutamyltransferase and urinalysis), and after histopathological evaluation of organs at necropsy. Based on the radiographic, clinical and anatomopathological findings, idiopathic HO was diagnosed.
