[The role of pharmacy residents as preceptors on clinical training].

Long-term clinical training programs started as part of a 6-year pharmacy course in May 2010. In order to provide training approaches more appropriately and efficiently, it is necessary for teaching facilities to develop effective training systems and curriculums. In Kobe City Medical Center General Hospital, a pharmacy residency system was instituted in 2009, and, based on this, a preceptorship program for clinical training was adopted. In this study, the influence of pharmacy residents as preceptors on clinical training was evaluated based on training reports submitted by 26 students, consisting of a total of 1238 pages; residents' comments were observed in 31.3% of them. Changes in students' awareness were also noted; in the course of training, they became more aware of the responsibility and role of pharmacists, and such awareness appeared to provide a basis for their future goals. Further, although most of the residents' comments were initially made for encouragement, concrete advice gradually increased with time. Residents' commitment to clinical training as preceptors may have facilitated students' understanding of the significance of training, while promoting their own development.

The antinociceptive and anti-inflammatory action of the CHCl3-soluble phase and its main active component, damnacanthal, isolated from the root of Morinda citrifolia.

Morinda citrifolia (Rubiaceae, Noni) is a traditional medicine with various pharmacological activities. We investigated if the MeOH-, CHCl(3)- and BuOH-soluble phase and its main active component, damnacanthal, isolated from the Noni root, have antinociceptive and anti-inflammatory actions in mice. The CHCl(3)-soluble phase (3 g/kg, per os (p.o.)) significantly reduced pain-related behavior observed in the formalin test. These effects were not suppressed by pretreatment with naloxone (1 mg/kg, intraperitoneally (i.p.)), an opioid receptor antagonist. The CHCl(3)-soluble phase (3 g/kg, p.o.) significantly reduced histamine-induced paw edema. The MeOH- and BuOH-soluble phase had no effect in either test. Furthermore, damnacanthal (10-100 mg/kg, p.o.) exerted an antinociceptive effect on chemical nociceptive stimuli, and decreased histamine-induced paw edema. Damnacanthal was weakly bound to the histamine H(1) receptor. These data suggest that the CHCl(3)-soluble phase of the Noni root has antinociceptive and anti-inflammatory effects. Furthermore, these effects of damnacanthal isolated from the Noni root is mediated in part by the histamine H(1) receptor.
