This study was designed to examine the prevalence and the risk factors of poor sleep quality in 4318 incoming university students in Taiwan. The test battery comprised a self-administered structured questionnaire, including items related to personal medical history and lifestyle habits, the Measurement of Support Functions (MSF), Pittsburgh Sleep Quality(More)
The present study examined the relationship between the Lie scale scores and striatal D(2)/D(3) receptor availability with respect to the cerebellum in 42 healthy community volunteers in Taiwan using single photon emission computed tomography (SPECT) with [(123)I]iodo-benzoaminde (IBZM). Even after controlling of age and educational level, subjects' Lie(More)
This study was designed to explore the risk factors of Internet addiction in 1360 freshmen of the National Cheng Kung University in Taiwan in 2003. The test battery included a self-administrated structured questionnaire, the Chinese Internet Addiction Scale-Revision (CIAS-R), the 12-item Chinese Health Questionnaire (CHQ-12), the Measurement of Support(More)
OBJECTIVE In vivo imaging studies have revealed deregulated presynaptic or postsynaptic function of the midbrain dopaminergic system in patients with schizophrenia. To further delineate the neuropathological involvement of the presynaptic and postsynaptic dopamine neurons in schizophrenia, the authors examined brain D(2)-family receptor and dopamine(More)
The aims of this study were to examine the differences between 32 opioid-dependent users treated with a very low dose of methadone or undergoing methadone-free abstinence and 32 controls. SPECT analysis using [99mTc] TRODAT-1 to assess striatal dopamine transporter (DAT) availability and [123I] ADAM to assess midbrain serotonin transporter (SERT)(More)
Recent lines of research suggest that, in addition to hypothalamic sites, the striatum dopaminergic system may be a target for regulating homeostasis that may be represented by the body mass index (BMI). Although it has been reported that the striatal dopamine receptor (DRD2) availability of very obese individuals was reduced in proportion to their BMI, the(More)
The purpose of the present paper was to remind physicians that hypothermia is a possible side-effect of combining zotepine, valproate,and benzodiazepine. Two cases of hypothermia occurred after combining the use of zotepine, valproate, and benzodiazepine. The valproate was under therapeutic blood level when zotepine dosage was raised to 200 mg/day, and(More)
BACKGROUND Although studies have indicated that the frontal lobe plays an important role in performance on the Wisconsin Card Sorting Test (WCST) and that basal ganglia play a specific role in frontal lobe function, the role of striatal dopamine (DA) activity in performance on the WCST remains unclear. METHODS We assessed the relation between the(More)
Accrued evidence demonstrated the necessity of protein synthesis at acquisition, consolidation and expression stages in conditioning/learning tasks, while the underlying mechanisms of the maintenance of memory remained less explored. This study was designed to characterize the maintenance of methamphetamine-induced conditioned place preference, a(More)
A novel RIA was used to examine the release of agouti-related protein-like immunoreactivity (AGRP-LI) from perfused rat hypothalamic tissue slices and to characterize AGRP-LI in rat serum. A continuous low level basal AGRP-LI release was observed from hypothalami of rats fed ad libitum before the rats were killed. Basal AGRP-LI release was 3-fold greater in(More)
