Introduction: A health assessment sheet was developed to establish a new method for post marketing surveillance (PMS) for nonprescription drugs, the status of which has recently been switched from prescription (Rx) to over-the-counter (OTC) to confirm the efficacy and safety of Rx-to-OTC switched drugs.  The assessment sheet was designed to evaluate adverse reactions that may be possibly induced by the drugs and to elicit spontaneous complaints from consumers.  An investigation using the assessment sheet had been conducted earlier for famotidine tablets.  While the earlier investigation suggested the effectiveness of the assessment method, it also revealed some issues.  After making improvements in the assessment sheet, another investigation was conducted for Loxonin®S.
Method: Purchasers of Loxonin®S were asked to tick symptoms that were applicable to them among those listed in the sheet.  They were asked to revisit the pharmacy and complete the sheet for the second time after drug administration.  The possibility of adverse reactions was considered for the symptoms additionally chosen at the second visit and they were then compared with the adverse reactions described in the package insert of Loxonin®S.
Results: Total 284 people completed the health assessment sheet at their first and second visits.  Of them, 44 people (15.5%) reported additional symptoms at the second visit.  Commonly reported symptom was “frequent experience of sleepiness,” “persistent headaches” and “fatigability.”
Conclusion: The study suggested that the health assessment sheet can be an effective tool for PMS for nonprescription drugs immediately after the Rx-to-OTC switch and contributes to detecting adverse reactions of the drugs.

This study aimed to elucidate how body composition, force-generating capacity and jump performances are associated with 50-m sprint velocity in circumpubertal boys, in relation to sprint phases and maturation. One hundred thirty four circumpubertal boys were allocated to preadolescent or adolescent group on basis of the height at the peak height velocity of Japanese boys (154 cm) reported in literature: those with body heights over 154 cm as adolescent group and others as preadolescent group. Body composition was determined by bioelectrical impedance analysis. In addition to maximal voluntary isometric knee extension torque, the performances of counter movement jump (CMJ), rebound jump (RJ), standing long jump (SLJ) and standing 5-step jump (SFJ) were also measured. RJ-index was calculated by dividing height by contact time. The time of 50-m sprint was determined at 10-m intervals. Multiple regression analysis showed that in preadolescent boys, SFJ become a predictor for the sprint speed during acceleration phases, and SFJ, RJ-index and CMJ as predictors for the sprint speeds during maximal speed and deceleration phases. In the adolescent boys, age, CMJ, SLJ, and SFJ become a predictor for the sprint speed during acceleration phases, and torque relative to body mass, CMJ and SFJ were selected as predictors for the sprint speeds during maximal speed and deceleration phases. Thus, the current results indicate that force-generating capacity and jumping ability are determinants for sprint performance in circumpubertal boys, but the relative contribution of each of the two factors differs between preadolescent and adolescent stages and among the sprint phases.

Many of the students belonging to the School of Health and Social Services will be responsible for health education in the future, and it is important that they have an understanding of the importance of Kampo medicine and the ability to give appropriate guidance in the field. But their educational goals need discussing. We conducted lectures on Kampo medicine with medical school students towards this end, and conducted before and after questionnaire surveys to gauge their effect. Students with a desirable degree of awareness toward Kampo medicine in Japanese society increased from 58.0 ± 15.4% to 88.5 ± 10.2%, and students judging Kampo as either useful or extremely useful rose from 58.4% to 95.9%. It is our hope that, with the raised awareness from these lectures as a base, these students will go on to engage in suitable medical educational activities in the future.

This study aimed to determine the relationships between the torque generating capacity of the lower extremity muscles and either running or jump performance in primary and junior high school boys. A total of 102 primary and junior high school boys participated in this study. Muscle thicknesses (MTs) of the knee extensors and plantar flexors were determined using ultrasonography. Muscle volumes (MVs) of the knee extensors and plantar flexors were estimated using MTs and limb lengths. The isometric joint torques (TQs) for knee extensors and ankle plantar flexors were measured using myometer. MV and TQ were divided by body mass (MV/BM and TQ/BM, respectively). Running velocity was measured using a non-motorized treadmill. The counter movement jump (CMJ) and squat jump (SJ) were performed on a matswitch system. The flight time was measured and used to calculate the heights of CMJ and SJ using the following equation; height (cm) = g × (flight time)² /8/10. As the result of multiple regression analysis, age, MV/BM and TQ/BM were selected as predictors of running velocity in the primary school boys, whereas TQ and lean body mass in junior high school boys. In the primary school boys, TQ/BM and body fat mass was selected as significant contributors for SJ and CMJ performances, whereas, in the junior high school boys, TQ and the percent of body fat for SJ performance and MV/BM and TQ for CMJ performance. Thus, the present results indicate that the relationships between torque generating capacity of the lower extremity muscles and either running or jump performance differ between primary and junior high school boys. It may be assumed that, for running and jump performances, muscle mass and strength become determinant factors in junior high school boys, whereas their values relative to body mass in primary school boys.

In order to find an effective way to detect bacteria responsible for respiratory tract infections in children, we first examined as pharyngeal swabs, epi-pharyngeal swabs and nasal aspirates obtained from children hospitalized at our pediatric service during these five months from December 1997 to April 1998. In the rate of bacterial infection, it was found that nasal aspirates came out on top with 92.6%(25/27), followed by epipharyngeal swabs with 71.6%(53/74) and pharyngeal swabs with 26.2%(38/145). Single-species bacteria were found in 78.9%(30/38) of pharyngeal swabs, where as 45.3% of epi-pharyngeal swabs (24/53) and 52.0% of nasal aspirates (13/25) proved mixed infections with two-or three-defferent species. Thus it was suggested that nasal aspirates and epi-pharyngeal swabs would be far more adequate than pharyngeal swabs to detect bacteria with accuracy.
Next, based on the efficiency of bacterial detection, we compared culture media for the specimen obtained from in-patients and out-patients at our pediatric service. The rate of isolation of gram-negative rods was as low as 0.3%(1 of 314 strains) even when BTB agar plate, a selective medium for these bacteria, was employed. The sensitivety was not much different from those observed with nonselective blood agar plate. These results suggest that the conventional blood agar media can substitute for the more expensive type of BTB agar medium for the diagnosis of infections diseases of the airwaysin children.

OBJECTIVE: Accumulating evidence suggests that oxidative stress plays a role in the pathophysiology of schizophrenia and that the potent antioxidants may be potential therapeutic drugs for schizophrenia. This study was undertaken to examine the effects of the potent antioxidant sulforaphane (SFN), found in cruciferous vegetables, on behavioral abnormalities (e.g., hyperlocomotion and prepulse inhibition [PPI] deficits) in mice after a single administration of the N-methyl-D-aspartate (NMDA)-receptor antagonist phencyclidine (PCP). METHODS: Effects of SFN (3, 10, and 30 mg/kg, intraperitoneally [i.p.]) on hyperlocomotion and PPI deficits in the adult male ddY mice after administration of PCP (3.0 mg/kg, subcutaneously [s.c.]) were examined. RESULTS: Administration of SFN (30 mg/kg, intraperitoneally [i.p.]), but not low doses (3 and 10 mg/kg, i.p.), significantly attenuated hyperlocomotion in mice after PCP administration (3.0 mg/kg, subcutaneously [s.c.]). Furthermore, administration of SFN (3, 10, and 30 mg/kg, i.p.) attenuated the PPI deficits in mice after PCP administration (3.0 mg/kg, s.c.) in a dose-dependent manner. CONCLUSION: These results suggest that SFN has antipsychotic activity in an animal model of schizophrenia. Therefore, it is likely that SFN may be a potential therapeutic drug for schizophrenia.

Purpose: It is critical to reduce complications associated with the central venous access port (CV-port) system for patients who were treated with chemotherapy or palliative care. Methods: From October 2006 to December 2011, 68 colon cancer patients who were treated with outpatient chemotherapy via a CV-port in the Center for Clinical Oncology, Okayama University Hospital, were analyzed retrospectively. Results: CV-port related complications occurred in 20 (29.4%) patients. No blood could be aspirated in 15 patients when treated via a CV-port. Among the patients with no blood aspiration from their CV-port, ten cases had no complications other than failure of blood aspiration, and anticancer agents have been successfully administered. However, the other five patients had their CV-port system replaced due to complications. Subclavian and left side insertions were the risk factors for catheter occlusion or inability to aspirate blood. Conclusion: Medical staffs should be aware that approximately one-third of the cases with no blood aspiration potentially have troubles with their CV-ports that need to be replaced.
