BACKGROUND Treadmill training is used for promoting rhythmical vigorous walking and for task-related training in patients with stroke. The neurological impact of treadmill training has not been established. The present investigation is aimed at (1) examining neurological changes over a four-week period after middle cerebral artery occlusion (MCAO) in rats and (2) assessing the impact of one-wee...

OBJECTIVES Clinical evidence suggests that neurological lesions can protect from arthritis. Acute cerebral ischaemia induces severe immunosuppression, resulting in enhanced susceptibility to infections. We aimed to determine if stroke-induced immunosuppression can ameliorate arthritis and to delineate the immunological mechanisms involved. METHODS Unilateral cerebral ischaemia was induced in ...

Middle cerebral artery occlusion(1) (MCAO) is a widely used experimental technique in rodents to model both the short-term pathological events and longer term neuroanatomical and functional damage associated with focal ischemia. Various neurobehavioral tasks have been developed to assess the motor and cognitive dysfunctions associated with MCAO in rodents, and these studies have revealed defici...

Manipulation of the central endothelin (ET) system via either ETA antagonists or ETB agonists following experimental cerebral ischemia has been shown to be beneficial in previous experimental studies. In order to further explore the involvement of these receptors in cerebral ischemia, we determined changes in binding affinity (Kd) and density (Bmax) of ETA and ETB receptors in the rat brain at ...

Curcumin exerts a protective effect in cerebral ischemia through its anti-oxidant and anti-inflammatory activities. γ-enolase is a glycolytic enzyme expressed in neurons that is known to exerts a neuroprotective effect. We investigated whether curcumin regulates γ-enolase expression in focal cerebral ischemic injury in rats. Middle cerebral artery occlusion (MCAO) was performed to induce focal ...

The purpose of this study is to determine the possible effect of photoluminescence of bioceramic (PLB) on ischemic cerebral infarction (stroke), by using an animal model of transient middle cerebral artery occlusion (MCAO). Sprague-Dawley rats were used to induce MCAO to block the origin of the left MCAO; three months later, the positive chronic stroke rats were selected by running tunnel maze;...

Klíčová slova dekompresní kraniektomie – mozkový infarkt – střední mozková tepna (ACM) – krysa Abstract We investigated the effects of decompressive craniectomy in a rat model of „malignant“ middle cerebral artery (MCA) infarction. A total of 55 male Sprague-Dawley rats weighing 290–340 g were allocated to the following groups: (1) Sham operated group (group 1, n = 14, as controls); (2) MCA occ...

BACKGROUND Achyranthes bidentata Blume (A. bidentata) is a commonly prescribed Chinese medicinal herb. A. bidentata polypeptides (ABPP) is an active composite constituent, separated from the aqueous extract of A. bidentata. Our previous studies have found that ABPP have the neuroprotective function in vitro and in rat middle cerebral artery occlusion (MCAO) model in attenuating the brain infrac...

Lung cancer complications are the leading cause of death in lung patients. This study aimed to describe prevalence stent placement, indications for success and complication rates, prognosis airway placement patients with cancer. Malignant central obstruction (MCAO) is one significant complications. Insertion can restore patency more than 90% MCAO. Airway indicated extrinsic lesions, ≥ 50%, have...

BACKGROUND AND PURPOSE The present study was performed to determine the role of alpha4 (CD49d), a member of the integrin family of adhesion molecules, in ischemic brain pathology. METHODS Male spontaneously hypertensive rats (SHR) or Sprague-Dawley rats underwent 60-minute middle cerebral artery occlusion (MCAO) followed by 23-hour reperfusion. Animals were injected intravenously with 2.5 mg/...
