Hereditary dentatorubral-pallidoluysian atrophy (DRPLA) is an autosomal dominant neurologic disorder characterized by variable combinations of myoclonus, epilepsy, cerebellar ataxia, choreoathetosis and dementia. By specifically searching published brain cDNA sequences for the presence of CAG repeats we identified unstable expansion of a CAG in a gene on(More)
To elucidate how the size of the expanded CAG repeat of the gene for dentatorubral pallidoluysian atrophy (DRPLA) and other factors affect the atrophy of the brainstem and cerebellum, and the appearance of high-intensity signals on T2-weighted MRI of the cerebral white matter of patients with DRPLA, we quantitatively analyzed the MRI findings of 26 patients(More)
Dentatorubral-pallidoluysian atrophy is an autosomal dominant neurodegenerative disease characterized by various combinations of ataxia, choreoathetosis, myoclonus, epilepsy, and dementia as well as a wide range of ages at onset. A specific unstable trinucleotide repeat expansion in a gene on the short arm of chromosome 12 was recently identified as the(More)
Bronchial asthma induced by contact with hamsters and other small rodents is receiving higher attention from the medical profession not only because of the problem of laboratory animal allergies (LAA), but also because of increasing household allergens for asthma, since keeping these pets has become more common in Japanese homes. The present report(More)
The relationship between systemic infection or inflammation and an increased risk of thrombotic diseases has recently raised renewed interest. In order to determine the mechanisms underlying this relationship, we determined plasma levels of coagulation/fibrinolysis markers and platelet function in patients with acute thrombotic stroke (<24 h after onset)(More)
OBJECTIVES Mutational analysis of the sterol 27-hydroxylase (CYP27) gene was performed on three patients from two Japanese families who had cerebrotendinous xanthomatosis (CTX) associated with parkinsonism. METHODS Clinical evaluations, brain MRI studies, and laboratory analyses were completed on the three patients. The CYP27 gene was analysed for(More)
During a three-year period (1987 & 1990), a comprehensive attempt was made to isolate verocytotoxin-producing Escherichia coli (VTEC) from 96 bovine, 89 porcine, 67 canine and 18 feline cases suffering from gastroenteritis. VTEC were isolated from 11 cows and 1 cat. Bead-ELISA and oligonucteotide probes were used to type the verotoxins (VT) and it was found(More)
We documented the presence of a point mutation in the tRNA(Lys) gene of mitochondrial DNA (mtDNA) in various postmortem tissues from two patients with myoclonus epilepsy associated with ragged-red fibers (MERRF). The percentages of the mutant mtDNA were similar (93 to 99%) in both clinically affected and unaffected tissues, suggesting that preferential(More)
It has been reported that the biosynthesis of thromboxane A2 (TXA2) is enhanced in platelets in the presence of chronic obstructive pulmonary disease (COPD), and 11-dehydro-TXB2, a urinary metabolite of thromboxane, also increases in blood. In the present study, seratrodast (CAS 112665-43-7, Bronica), a TXA2 receptor antagonist, was administered to 14(More)
A comparative study was conducted in elderly subjects with mild bronchial asthma to investigate the clinical usefulness of monotherapy with a leukotriene receptor antagonist in comparison to an inhaled corticosteroid. A total of 41 elderly patients aged 65 years or older with mild bronchial asthma, classified as being in severity step 1 and 2, were randomly(More)
