In Experiment 1, the 5-HT uptake blocker fluoxetine (FLX; 20 mg/kg) reduced the proportion of sexually experienced male rats displaying ejaculations. Among those animals that did ejaculate there was an increase in intromission frequency (IF), ejaculation latency (EL), and postejaculatory interval (PEI) and a reduction in copulatory efficiency (CE) during(More)
Hypotaurine is an intermediate in taurine biosynthesis from cysteine in astrocytes. Although hypotaurine functions as an antioxidant and organic osmolyte, its physiological role in the central nervous system remains unclear. This study used behavioral assessments to determine whether hypotaurine influenced nociceptive transmission in acute, inflammatory,(More)
O-desmethyl tramadol is one of the main metabolites of tramadol. It has been widely used clinically and has analgesic activity. Muscarinic receptors are involved in neuronal functions in the brain and autonomic nervous system, and much attention has been paid to these receptors as targets for analgesic drugs in the central nervous system. We have reported(More)
Chlorogenic acid (CGA), one of the most abundant dietary polyphenols, is known to have various physiological properties. Although CGA is reported to have an antinociceptive effect on acute and inflammatory pain, little is known about its effect on neuropathic pain or its action site. The aim of the present study was to determine whether intrathecally(More)
Rats were trained to respond under a differential reinforcement of low rate (DRL) schedule of reinforcement. Pretreatment with relatively low doses of chlordiazepoxide (1-10 mg/kg) produced increases in total DRL responses and decreases in the numbers of reinforced responses. Chlordiazepoxide produced a shift in the interresponse time (IRT) distribution of(More)
Celecoxib is a specific inhibitor of cyclooxygenase 2 (COX2). While it has been used for the treatment of chronic inflammatory conditions, including rheumatoid arthritis, its detailed anti-inflammatory mechanism has not been clarified. Here, we found that Celecoxib potently inhibited TNFalpha-induced transcriptional activity and DNA binding activity of(More)
UNLABELLED We examined the reliability of an airway evaluation test to assess the occipitoatlantoaxial (OAA) extension capacity described by Bellhouse et al. (Bellhouse test) in 20 adult volunteers with normal cervical spines. Each subject sat upright with the head in the neutral position and was then asked to extend the head maximally while attempting to(More)
Luteolin, a major component of flavones, is known to have various physiological properties. Although luteolin reportedly has an antinociceptive effect on acute and inflammatory pain, little is known about its effect on neuropathic pain. The aim of the present study was to determine whether luteolin could ameliorate hyperalgesia in the central nervous system(More)
There have been several reports on anesthesia for a patient with a history of multiple drug allergies. We present here anesthesia for a 33-year-old woman with histories of multiple drug allergies. She was scheduled to undergo total abdominal hysterectomy. We could not perform preoperative screening of the drugs using a dermal test because of a high risk of(More)
