Satisfactory results have not yet been obtained in therapy for secondary prevention in ischemic stroke patients with antiphospholipid syndrome (APS). We therefore compared single antiplatelet therapy and a combination of antiplatelet and anticoagulation therapy for secondary prevention in ischemic stroke patients with APS.The subjects were 20 ischemic(More)
We have developed a novel, non-toxic inhibitor of advanced glycation and oxidative stress, TM2002, devoid of effect on blood pressure. In transient focal ischemia, TM2002 significantly decreased infarct volume compared with vehicle (79.5+/-18.7 vs. 183.3+/-22.9 mm3, p<0.01). In permanent focal ischemia, TM2002 (2.79, 5.58, and 11.16 mg/kg twice a day)(More)
The diagnosis of migraine can sometimes be difficult because some patients do not fulfill the International Headache Society's criteria for migraine. Hence, an accurate and reliable diagnostic marker for migraine is required. In this study, lymphocytes were used to establish Epstein-Barr virus (EBV)-immortalized lymphoblast cell lines, which were then(More)
Bilateral medial medullary infarction (bilateral MMI) is an extremely rare cerebrovascular accident presenting with quadriplegia as the initial symptom and resulting in poor functional prognosis. Diagnosis of bilateral MMI has become possible based on brain MRI findings in recent years, but is still very difficult to diagnose. In the present case, brain MRI(More)
Cerebral infarction (CI) is a complex multifactorial disorder that is thought to result from the interaction of various environmental factors and an individual's genetic make-up, including genes associated with platelet activation. In order to clarify whether single nucleotide polymorphisms (SNPs) of the prostacyclin receptor (IP) gene affects platelet(More)
Our aim was first to evaluate the association between blood vessel density (BVD) and free platinum concentration in experimentally induced tumours in rabbits. We also investigated the association between tumour BVD and the clinical response of patients who had undergone targeted carboplatin intra-arterial (i.a.) chemoradiotherapy. VX2 carcinoma cells were(More)
A 71-year-old Japanese woman with Sjögren syndrome, Hashimoto's disease and a 6-month history of cognitive impairment was admitted to our hospital because of consciousness disturbance and convulsion. Her convulsive seizure disappeared by intravenous administration of diazepam following carbamazepine, and conscious level became alert the next day. But, her(More)
We investigated the effect of the subcutaneous administration of hematopoietic cytokines, granulocyte colony-stimulating factor (G-CSF)+stem cell factor (SCF), on mRNA expression of tissue cytokines in the acute or subacute phase after focal ischemia in male C57 BL/6J mice. The expression of IL-10 mRNA was elevated at 4-14 days after occlusion when(More)
We investigated whether intra-arterial administration of carboplatin using Calvert's formula is useful for avoiding thrombocytopenia in targeted chemoradiotherapy in patients with squamous cell cancer of the oral cavity and oropharynx. Carboplatin was infused intra-arterially under digital subtraction angiography in 28 patients. In the first group of(More)
BACKGROUND Atrial fibrillation (AF) is an important risk factor for transient ischemic attack (TIA). However, little is known about the characteristics of TIA patients with AF. This study investigated the characteristics of such patients, using data from a retrospective, observational, multicenter study. METHODS TIA patients admitted to 13 stroke centers(More)
