Objective: Adequate periconceptional folic acid intake decreases the risk of neural tube defects in infants.  The present study aimed to investigate the awareness of pharmacy students regarding the importance of folic acid intake for the prevention of neural tube defects.
Design: Questionnaire survey.
Methods: A self-administered questionnaire regarding the importance of folic acid intake for the prevention of neural tube defects was distributed to 750 pharmacy students at Tohoku and Ohu Universities.
Results: Among the 685 respondents (response rate; 91.3%), 74 (10.8%) were aware that folic acid intake decreases the risk of neural tube defects.  In multivariate logistic regression analysis, awareness of the importance of folic acid intake was evident among 5th- and 6th-year pharmacy students (odds ratio=3.352, 95% confidence interval=1.797-6.253) and among those who used dietary supplements (2.275, 1.306-3.966).  Among the 74 pharmacy students who recognized the importance of folic acid intake, 17 (23.0%) and 3 (4.1%) were aware that women should begin taking a folic acid supplement before conception and should take about 400 μg per day during pregnancy, respectively.
Conclusion: Only about 10% of the pharmacy students in this study recognized that folic acid intake decreases the risk of neural tube defects, and many were unaware of the recommended intake amount.  Therefore, awareness of the importance of folic acid intake must be more aggressively promoted among pharmacy students.

Objective: Adequate periconceptional intake of folic acid decreases the risk of neural tube defects of infant. The present study aimed to investigate the awareness of nursing students about the importance of folic acid intake for the prevention of neural tube defects.Design: Questionnaire survey.Methods: A self-administered questionnaire regarding the importance of folic acid intake for the prevention of neural tube defects was distributed to 423 nursing students of Tohoku University and Tohoku Fukushi University.Results: Among the 408 respondents (response rate; 96.5%), 129 (31.6%) nursing students were aware that folic acid intake decreases the risk of neural tube defects. In the multivariate logistic regression analysis, grade 3-4 (odds ratio = 11.779, 95% confident interval = 5.739-24.177) were associated with the awareness of the importance of folic acid intake among nursing students. Of 129 nursing students who recognized the importance of folic acid intake, 52 (40.3%) and 11 (8.5%) recognized that women should begin folic acid intake before conception and should take about 400μg of folic acid per day during pregnancy respectively.Conclusion: About 30% of nursing students recognized that folic acid intake decreases the risk of neural tube defects and many did not know the details of the effective intake for the prevention of neural tube defects. Therefore, more aggressive promotion of the awareness of the importance of folic acid intake among nursing students is warranted.

The inhibitory effects of the freeze-dried powder of the aqueous extract of black tea leaf (JAT) on α-glucosidase activity were investigated. We initially examined the effects of JAT addition on yeast α-glucosidase activity. JAT significantly and dose-dependently inhibited α-glucosidase activity and more strongly inhibited the activity than acarbose, the positive control. Then, we examined the effects of oral administration of JAT on sucrose tolerance in type 2 diabetes mellitus model db/db mice. Both JAT and acarbose administered groups showed a dose-dependent decrease in plasma glucose levels after the sucrose loading compared with the control group. Notable was that the plasma glucose levels of the 500 mg/kg JAT administered group exhibited a significant decrease 30 min or longer after the sucrose loading. On the other hand, no significant difference in plasma insulin levels was seen between the JAT administered group and the control group. We also measured small intestinal sucrase activity in db/db mouse at 30 min after JAT oral administration. Compared to control mice, small intestinal sucrase activity was significantly decreased in the 500 mg/kg JAT administered mice. These findings indicate that JAT may be a useful natural material for the prevention and therapy of type 2 diabetes mellitus.

  A 16-year-old male with autism underwent a preanesthetic examination under intravenous sedation before dental surgery under general anesthesia, because he had resisted all treatment.  To relieve the patient of physical and mental stress before he was brought to the operating room and venipuncture was performed for an intravenous drip, we administered midazolam to him orally.  The patient was in the habit of having coffee every morning using the same cup. Such adherence is characteristics of autismtic individuals. We, therefore, put midazolam in his morning cup. He drank it with good grace. As a result, he fell into a sedated state. We were thereafter able to smoothly bring on general anesthesia.  Our experience suggested that careful management allowing for disease characteristic could lead to the provision of hogh-quality medical services for mentally challenged patients.

The purpose of this study was to compare the effect between cyclists and noncyclists of pedal rates on ankle, knee, and hip joint torque during pedaling exercises. Six male cyclists (CY) and seven male noncyclists (NC) pedaled at 40, 60, 90 and 120 rpm with a power output of 200 W. The lower limb was modeled as three rigid segment links constrained to plane motion. Based on the Newton-Euler method, the equation for each segment was constructed and solved on a computer using pedal force, pedal, crank, and lower limb position data to calculate torque at the ankle, knee, and hip joints. The average planter flexor torque decreased with increasing pedal rates in both groups. The average knee extensor torque for CY decreased up to 90 rpm, and then leveled off at 120 rpm. These results were similar to NC. The average knee flexor torque in both groups remained steady over all pedal rates. The average hip extensor torque for CY decreased significantly up to 90 rpm where it showed the lowest value, but increased at 120 rpm. For NC, the average hip extensor torque did not decrease at 90 rpm compared with 60 rpm, and was significantly higher than CY at 120 rpm (CY : 28.1 ± 9.0 Nm, NC : 38.6 ± 6.7 Nm, p<0.05) . The average hip flexsor torque for NC at 120 rpm increased significanly from 90 rpm, and was significantly higher than CY (CY : 11.6±2.9 Nm, NC : 22.6±11.8 Nm, p<0.05) . These results suggest that it would be better for cyclists to select a pedal rate of between 90 to 110 rpm to minimize joint torque, and, as a result, reduce peripheral muscle fatigue.
