Ghrelin receptors are present in the central nervous system. We hypothesized that ghrelin released from the stomach acts as an endocrine substance and stimulates brain stem vagovagal circuitry to evoke pancreatic secretion. In an in vivo anesthetized rat model, an intravenous infusion of ghrelin at doses of 5, 10, and 25 nmol increased pancreatic protein(More)
BACKGROUND & AIMS We have identified that the anterior cingulate cortex (ACC) neurons are responsive to colorectal distention (CRD) and shown that sensitization of ACC neurons occurs in viscerally hypersensitive rats. However, the role of the ACC in pain response has not been clearly defined. We aimed to determine if ACC neuron activation enhances visceral(More)
AIM To investigate the influences of bile reflux on profiles of gastric mucosal lesions in patients with dyspepsia or chronic gastritis. METHODS A total of 49 patients diagnosed with dyspepsia and chronic gastritis underwent 24-h ambulatory and simultaneous monitoring of intragastric bilirubin absorbance and pH values, and then they were divided into bile(More)
Budgerigar fledgling disease is an acute viral infectious disease caused by avian polyomavirus (APV). In this study, 34 liver tissue samples of young, dead budgerigar with typical symptoms were collected in 2004. All the samples had positive polymerase chain reaction (PCR) test based on the VP1 specific primers. VP1 genes of these samples were sequenced and(More)
BACKGROUND & AIMS Electrophysiologic and behavioral studies have shown that increased N-methyl-D-aspartate (NMDA)-receptor activation of anterior cingulate cortex (ACC) neurons has a critical role in modulating visceral pain responses in viscerally hypersensitive (VH) rats. This study aimed to identify the NMDA receptor subtypes in perigenual ACC (pACC)(More)
BACKGROUND AND AIM Methyl or 1, N(6) -ethenoadenine base lesions are frequent and highly-mutagenic or -carcinogenic events in mammalian DNA. Human AlkB homologue-2 (hABH2), a homologue of the Escherichia coli AlkB protein, has been found to be the principal dioxygenase for the repair of these lesions. Mounting evidence indicates that impaired DNA repair(More)
AIM To investigate the incidence of nocturnal dyspeptic symptoms in patients with functional dyspepsia (FD) and whether prokinetic drugs can alleviate them. METHODS Eighty-five consecutive Chinese patients with FD were included in this study. One week after single-blinded placebo run-in treatment, baseline nocturnal intragastric pH, bile reflux and(More)
The NR2B subunit of NMDA receptor in the anterior cingulate cortex (ACC) is up-regulated in viscerally hypersensitive (VH) rats induced by colonic anaphylaxis. It plays a critical role in modulation of ACC sensitization and visceral pain responses. Given the key role of calcium/calmodulin-dependent protein kinase II (CaMKII) in synaptic plasticity and(More)
Avian influenza H5N1 viruses pose a significant threat to human health because of their ability to infect humans directly. In the paper, three highly pathogenic H5N1 influenza viruses were isolated from three species of migratory birds in Qinghai Province of China in 2006. The analysis of the genome sequences indicated that the three isolates shared high(More)

Converging lines of evidence demonstrate a vagally mediated antinociceptive pathway in animals undergoing acute visceral insults, the contribution of this system to visceral pain following chronic noxious stimuli is unknown. 5-HT(3) receptor (5-HT(3)Rs) on spinal afferents are crucially involved in nociceptive processing, the role of 5-HT(3)Rs on vagal(More)
