Immunologically induced fatigue was induced in rats by intraperitoneal injection of a synthetic double-stranded RNA, polyriboinosinic : polyribocytidylic acid (poly I:C). An injection of poly I:C (3 mg/kg) decreased the daily amounts of spontaneous running wheel activity to approximately 60% of the preinjection level until day 8. Quantitative analysis of(More)
Fatigue is evoked not only by peripheral factors, such as muscle fatigue, but also by the central nervous system (CNS). For example, it is generally known that the feeling of fatigue is greatly influenced by psychological aspects, such as motivation. However, little is known about the central mechanisms of fatigue. The clinical symptoms of chronic fatigue(More)
Somatic symptoms are known to be a prominent characteristic in patients with depression. The aim of the present study was to investigate the major somatic and psychiatric symptoms associated with depression in each sex. Patients with a DSM-IV diagnosis of depressive disorders (n=335) and comparison patients without depression (n=423) among new outpatients(More)
Recent figures show that more than 30,000 people suicide each year in Japan, and that many of them are considered to suffer from depression. In addition, the suicide rate among Japanese women has been shown to be higher than in other countries. However, it is not clear whether the psychiatric symptoms leading to suicide differ by gender.

To investigate the age-related changes in the expression of interleukin-1beta (IL-1beta) and its related substances in the brain during heat stress, we measured amounts of mRNAs for IL-1beta, cyclooxygenase-2 (COX-2), and an inhibitor of nuclear factor (NF)-kappaB-beta (IkappaB-beta) that is known to reflect an activation of NF-kappaB, in the cortex,(More)
The effects of recombinant mouse stem cell factor (rmSCF) on paired-pulse facilitation (PPF) and long-term potentiation (LTP) in the mossy fiber (MF)-CA3 pathway were examined in mouse hippocampal slices by recording field EPSPs. When PPF was measured before and 30 min after tetanic stimulation, the initial PPF positively correlated with the amplitude of(More)
Patients with suicidal ideation (SI) have various mental or somatic symptoms. A questionnaire-based interview elicited details concerning mental and somatic symptoms in patients visiting a psychosomatic clinic in Japan. Univariate logistic regression analyses followed by multiple regression models using a stepwise method were selected for identifying the(More)
