This study was undertaken to elucidate the anticonvulsive effects of zonisamide (ZNS: 25, 50, and 75 mg/kg, intraperitoneal [i.p.]), which was coadministered with valproic acid (VPA: 25, 50, and 100 mg/kg, i.p.), or phenytoin (PHT: 10, 25, and 50 mg/kg, i.p.) to ZNS concentration, nitric oxide metabolites (NOx levels), and monoamines in the brain of the EL(More)
To investigate changes of nitric oxide (NO) productions and zonisamide (ZNS) concentrations in the brain of seizure-susceptible EL mice given caffeine orally, mice were given caffeine (600 microg/mL) solution ad libitum as a drinking fluid for 1-3 weeks. Nitric oxide production in the brain was determined by measuring levels of nitrite plus nitrate (NOx).(More)
One hundred and ninety elderly people receiving home health service were investigated. The intellectual levels, depressive state evaluated by the Cornell scale for depression in dementia (CSDD) scale, abnormal behaviors evaluated by the dementia behavior disturbance (DBD) scale, and activities of daily living (ADL) were examined. These assessments were(More)
To clarify the role of nitric oxide (NO) in the pathogenesis of seizures in susceptible EL mice, we investigated effects of three drugs potentially related to NO production, MK-801, dantrolene, and FK506, on convulsive seizures and brain NO metabolites (NOx). MK-801 or dantrolene, but not FK506, suppressed convulsive seizures in EL mice; only MK-801 reduced(More)
To study factors which influence the quality of life (QOL) in the elderly, we investigated the relationship between scores on the modified Philadelphia Geriatric Center (JPGC) Morale Scale and various other psychological tests in 51 elderly people residing in a long-term care facility. The JPGC Morale Scale score correlated with the scores for all sections(More)
Female ddY mice were administered 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) by gavage for 8 weeks prior to pregnancy. In the male breast-fed offspring born to the TCDD-exposed mice, serotonergic neurons in the brainstem were examined using an immunocytochemical method at 42 days of age. In all offspring, a marked decrease in the intensity of immunostaining(More)
OBJECTIVES To survey the burden and psychological problems of family caregivers of demented people. DESIGN All scores were compared according to gender of the demented patients and which family members were the caregivers. SETTING Outpatients clinic at the university hospital and the day service system for the elderly. PATIENTS Sixty-two demented(More)
We report the cases of two patients with psychiatric stupor who developed venous thrombosis. A 29-year-old schizophrenic woman had been hospitalized in psychiatric institutions three times because of stupor associated with auditory hallucinations and thought blocking. These symptoms recurred and she was admitted to our hospital with deep venous thrombosis(More)
2,3,7,8-Tetrachlorodibenzo-p-dioxin (TCDD) is one of the most toxic environmental pollutants. In the present study, we examined c-Fos expression in the central nervous system (CNS) after administration of a lethal dose of TCDD to the adult Long-Evans rat to clarify if the CNS participates in TCDD-induced intoxication. A single dose of TCDD (dissolved in(More)
We evaluated the anticonvulsive effects of phenobarbital (PB) and zonisamide (ZNS) in the EL mouse, a strain that is highly susceptible to seizures. The concentration of each agent was analyzed in the serum and brain. PB suppressed the seizures dose-dependently, whereas even the higher dose of ZNS was ineffective in achieving a complete suppression. Serum(More)
