BACKGROUND AND PURPOSE Enlimomab, a murine monoclonal anti-human intercellular adhesion molecule (ICAM)-1 antibody, had a negative outcome in a multicenter acute-stroke trial. We did a bedside-to-bench study in standardized rat stroke models to explore mechanisms for these untoward results. METHODS After focal brain ischemia in Wistar rats and spontaneously hypertensive rats (SHR), we adminis...

Background/Aim: Perineural fibrosis may be seen in some surgeries after unsuccessful transforaminal injections. This animal experiment aims to investigate the effect of steroids and/or local anesthetic substances used epidural/transforaminal injections on fibrosis. Methods: A total 14 male Wistar-Albino rats were separated into two groups 7. After intraperitoneal anesthesia, right and left scia...

Background: Mitochondria are a source of reactive oxygen species (ROS), and several natural compounds used as antioxidant agents. This study aimed to investigate compare the effects fresh grape juice red wine on oxidative stress biomarkers in rat liver mitochondria. Materials Methods: In this regard, mitochondria were isolated from 27 male Wistar rats (220-250 g). The cultured different doses f...

This study was designed to determine whether diurnal patterns of blood pressure, heart rate, or locomotor activity differed among two substrains of Wistar-Kyoto rats, derived originally from Charles River or Taconic Farms stock, or the spontaneously hypertensive rat. Cardiovascular parameters were continuously monitored over 24 hours. Resting systolic and diastolic blood pressure values were st...

Erectile dysfunction is a major public health problem leading to harmful consequences for couples. Hence the need find adequate treatments using medicinal plants such as Pycnanthus angolensis, Cameroonian plant used treat erectile dysfunction. The effects of aqueous extract angolensis wood were evaluated on male rat sexual behavior and nitric oxide release. Adult Wistar rats divided into 4 grou...

The effects of age and blood pressure on fibronectin expression in the rat heart were studied in the normotensive Wistar and Wistar-Kyoto (WKY) strains and in the spontaneously hypertensive rat (SHR). Fibronectin mRNA expression decreased threefold between 10 and 40 weeks of age in Wistar hearts, with changes of similar magnitude occurring between 6 and 24 weeks in WKY rats. In contrast, no dec...

The superior colliculus (SC), substantia nigra pars reticulata (SNPr), and striatum have been characterized as important structures involved in the modulation of seizure activity. In the current study, bicuculline (GABA(A) antagonist) and muscimol (GABA(A) agonist) were microinjected into the deep layers of either the anterior SC (aSC) or posterior SC (pSC) of genetically developed Wistar audio...

introduction: in this study, we investigated the role of n-methyl-d-aspartate (nmda) receptors in the ventral hippocampus (vh) and their possible interactions with gabaa system on anxiety-like behaviors. methods: we used an elevated-plus maze test (epm) to assess anxiety-like behaviors and locomotor activity in male wistar rats. results: the results showed that intra-vh infusions of different d...

Rat is a major model organism in toxicogenomics and pharmacogenomics. Hepatic mRNA profiles after treatment with xenobiotic chemicals are used to predict and understand drug toxicity and mechanisms. Surprisingly, neither inter- and intra-strain variability of mRNA abundances in control rats nor the heritability of rat mRNA abundances yet been established. We address these issues by studying fiv...
