Daikenchuto (TJ-100) is a Japanese traditional herbal medicine that enhances postoperative enterokinesis and increases the intestinal blood flow. Daikenchuto has historically played a positive role in the perioperative management of gastrointestinal surgery. However, the effect of Daikenchuto on improving nutrition after cardiac operation has never been reported. This study evaluated the effect of Daikenchuto administration after cardiac operation. Eighty-four patients who underwent isolated first aortic valve replacement (AVR) at our department from May 2008 to December 2014 were enrolled in this study and retrospectively examined. We administered Daikenchuto when patients started their water intake. Blood tests were performed before and seven days after AVR. We prescribed Daikenchuto for 21 patients (group D). The reductions in the albumin level and prognostic nutritional index (p = 0.045, p = 0.008, respectively, multivariate analysis of variance) after the operation were significantly lower in group D (3.75 ± 0.3 to 3.33 ± 0.4 and 44.7 ± 4.8 to 41.3 ± 6.7 mg/dl, respectively) than in the group without Daikenchuto (group N, 63 patients) (3.74 ± 0.5 to 3.13 ± 0.4 and 44.6 ± 6.3 to 37.7 ± 5.3 mg/dl, respectively). There were no significant differences in the incidence rates of postoperative complications or hospitalization duration between the two groups. Postoperative Daikenchuto administration is considered to be safe and effective for improving the postoperative nutritional status after simple AVR as well as digestive surgery.

To clarify the effects of black carbon (BC) particles on growth and gas exchange rates of Asian forest tree species, the seedlings of Fagus crenata, Castanopsis sieboldii, Larix kaempferi and Cryptomeria japonica were exposed to BC particles with sub-micron size for two growing seasons from 1 June 2009 to 11 November 2010. The BC particles deposited after the exposure to BC were observed on the foliar surface of the 4 tree species. At the end of the experiment, the amount of BC accumulated on the foliar surface after the exposure to BC aerosols were 0.13, 0.69, 0.32and 0.58 mg C m-2 total leaf area in F. crenata, C. sieboldii, L. kaempferi and C. japonica seedlings, respectively. In August 2010, the exposure to BC particles did not significantly affect net photosynthetic rate under any light intensity, stomatal diffusive conductance to water vapour (gs), stomatal limitation of photosynthesis,response of gs to increase in vapour pressure deficit and leaf temperature under light saturated condition in the leaves or needles of the seedlings. These results suggest that the BC particles deposited on the foliar surface did not reduce net photosynthesis by shading, did not increase leaf temperature by absorption of irradiation light, and did not induce plugging of stomata in the leaves or needles of the seedlings. There were no significant effects of BC particles on the increments of plant height and stem base diameter during the experimental period and the whole-plant dry mass at the end of the experiment. These results indicate that the exposure to BC particles with sub-micron size for two growing seasons did not significantly affect the growth and leaf or needle gas exchange rates of F. crenata, C. sieboldii,L. kaempferi and C. japonica seedlings.
