2 week study was conducted to investigate the effects of Interferential Current(IC) and Kaltenborn-Evjenth Orthopedic Manual Therapy(KEOMT) on functional constipation. Interventions were applied to spinal segments between T9-L2 which provides innerva˗ tions to the gastrointestinal tract. Subjects(n=24) were randomly allo˗ cated to two treatment groups: the IC group or the KEOMT group. Results for the IC therapy demonstrated significant decrease with the colonic transit time(CTT) as well as scores on the constipation assessment scale(CAS). The frequency of defecations per week had increased significantly(p<0.05). The KEOMT displayed decreased CTT in the left colon region. The scores on the CAS were reduced and frequency of defecations per week had increased significantly (p<0.05). This study not only showed that both modes of therapy improved symptoms of constipation, but also optimized gastrointesti˗ nal content movement, eventuating in a more normalized CTT. In conclusion, both the IC therapy and the Kaltenborn-Evjenth Orthopedic Manual Therapy have shown to be effective interventions for improving functional constipation.

Background : Native oak tree species dominated the deciduous forests of South Korea. The acorns of them represent the main food source for wildlife species as well as human being, and they have 28 species. We analyzed and compared to the antioxidants including total phenolics and functional nutrients components among the acorns of nine kinds of oak trees (Quercus acutissima, Q. aliena, Q. mongolica, Q. variabilis, Q. serrata, Q, palustris, Q. rubra, Q. glauca, and Q. acuta). Methods and Results : Acorns were collected from each tree species, which were grown in a seed orchard. Contents of both total phenolic content (TPC) in acorns of Q. serrata were higher than others. Interestingly, Q. serrata contained the highest amount of water soluble tannins and the lowest levels of water insoluble tannins among 9 oak species, resulting that acorns of Q. serrata had the lowest proportion of insoluble tannins. Among 9 oak species tested, Q. aliena acorns contained the highest levels of total flavonoids content (TFC). Conclusion : Our result showed that nutritional composition of acorns was significantly different between oak species, indicating that tastes or nutritional values might be different as well among major oak species in Korea.
