Suppression of pancreatitis-related allodynia/hyperalgesia by proteinase-activated receptor-2 in mice
1. Proteinase-activated receptor-2 (PAR2), a receptor activated by trypsin and tryptase, is abundantly expressed in the gastrointestinal tract including the C-fiber terminal, and might play a role in processing of visceral pain. In the present study, we examined and characterized the roles of PAR2 in pancreatitis-related abdominal hyperalgesia/allodynia in mice. 2. Caerulein, administered i.p. once, caused a small increase in abdominal sensitivity to stimulation with von Frey hairs, without causing pancreatitis, in PAR2-knockout (KO) mice, but not wild-type (WT) mice. 3. Caerulein, given hourly six times in total, caused more profound abdominal hyperalgesia/allodynia in PAR2-KO mice, as compared with WT mice, although no significant differences were detected in the severity of pancreatitis between the KO and WT animals. 4. The PAR2-activating peptide, 2-furoyl-LIGRL-NH(2), coadministered repeatedly with caerulein six times in total, abolished the caerulein-evoked abdominal hyperalgesia/allodynia in WT, but not PAR2-KO, mice. Repeated doses of 2-furoyl-LIGRL-NH(2) moderately attenuated the severity of caerulein-induced pancreatitis in WT animals. 5. Our data from experiments using PAR2-KO mice provide evidence that PAR2 functions to attenuate pancreatitis-related abdominal hyperalgesia/allodynia without affecting pancreatitis itself, although the PAR2AP applied exogenously is not only antinociceptive but also anti-inflammatory
Expression of CD44v6 is an independent prognostic factor for poor survival in patients with esophageal squamous cell carcinoma
Start and initial results of the fukushima prefecture acute myocardial infarction registration survey
Acute myocardial infarction (AMI) remains one of the most serious heart diseases and elucidation of its pathogenesis and advances in treatment strategies have been desired. In 2009, to understand the status of AMI in Fukushima Prefecture for improving treatment outcomes, a new AMI registration survey system was conducted throughout the prefecture. A total of 1,556 cases were registered in the initial 2 years from 2009 to 2010. The hospital-based overall incidence of AMI in Fukushima Prefecture was 37.9 people per population of 100,000 per year. Mortality from AMI within 30 days of onset was 10.2%. We report herein the actual situation of AMI onset and treatment in Fukushima Prefecture based on the initial results of the survey
