Yokukansan (YKS), a traditional Japanese medicine, is composed of seven kinds of dried herbs. It is widely prescribed in clinical situation for treating psychiatric disorders such as aggressiveness in patients with dementia. We previously demonstrated that YKS and Uncaria hook (UH), which is a constituent herb of YKS, had a partial agonistic effect to(More)
We measured the levels of some biological metals: copper (Cu), iron (Fe), magnesium (Mg), manganese (Mn), and zinc (Zn) in the cerebrospinal fluid (CSF) in patients with neurodegenerative diseases (52 patients with amyotrophic lateral sclerosis (ALS)), 21 patients with Alzheimer's disease (AD), and 20 patients with Parkinson's disease (PD) by inductively(More)
The eighth nerve compound action potential (CAP) in 95 guinea pigs was measured using click stimuli to investigate age-related changes in their neural auditory thresholds. The animals were separated into three groups: group A (n = 43, 86 ears; 2-4 months old); group B (n = 29; 58 ears, 13-15 months old); and group C (n = 23; 46 ears, 23-25 months old). With(More)
Defect of metallothionein-III (MT-III) has been reported to be a contributor to the progression of amyotrophic lateral sclerosis (ALS). We explored the expression and effects of MT-III on the motor neurons of spinal cords of ALS model mice (G93A Cu/Zn superoxide dismutase (SOD-1) mutant-transgenic (Tg) mice) using a retrograde viral delivery system.(More)
Regular exercise has displayed a beneficial effect on the progression of amyotrophic lateral sclerosis (ALS). However, the mechanism is poorly understood. We here present that regular exercise on a treadmill induces metallothioneins (MTs: MT-1, MT-2, and MT-3) in spinal cords of mice. As MTs are strong scavengers of reactive oxygen species and have some(More)
Patients with marked calcification of the basal ganglia and cerebellum have traditionally been referred to as having Fahr's disease, but the nomenclature has been criticized for including heterogeneous etiology. We describe 3 patients with idiopathic bilateral striatopallidodentate calcinosis (IBSPDC). The patients were a 24-year-old man with mental(More)
The auditory brainstem response (ABR) and the eight nerve compound action potential (CAP) were measured using click click stimuli to investigate the age-related alteration in the auditory function in 66 guinea pigs consisting of four age groups. With advancing age, a gradual elevation of the thresholds in both the ABR and CAP was clearly seen, together with(More)
The remarkable calcification of the basal ganglia and cerebellum has been traditionally called Fahr’s disease, but this nomenclature is criticized for including heterogeneous diseases. To determine the pattern of some biological metals in the hair of patients with Fahr’s disease, we investigated the levels of 24 bioelements in the hair of 28 patients (17(More)
