A total of 14 367 pollen grains belonging to 40 taxa have been identified and recorded with some unidentified ones. Of them, 6 732 were identified in 1999 and 7 635 in 2000. Of the total pollen grains, 69.67% were arboreal, 26.64% non_arboreal and 3.68 % unidentified. The majority of the investigated pollen grains were from Pinus, Gramineae, Cupressaceae, Platanus , Chenopodiaceae/Amaranthaceae, Quercus, Ailanthus, Moraceae, Juglans , Salix, Cedrus and Rosaceae. The highest level of pollen grains was in May.展开更多

Methods： Nineteen children with ADHD （aged between 8 and 12 years old） undertook a 30-min intervention that consisted of treadmill running or video-watching presented in a counterbalanced order on different days. A Go/No Go Task was administrated after exercise or video-watching. Results： The results indicated a shorter reaction time and smaller contingent negative variation （CNV） 2 amplitude following exercise relative to the video-watching. For event related potential （ERP） analyses, greater CNV l and CNV 2 amplitudes in response to No Go stimuli in com- parison to Go stimuli was observed in the video-watching session only. Conclusion： These findings suggest that acute exercise may benefit children with ADHD by developing appropriate response preparation, particularly in maintaining a stable motor preparatory set prior to performing the given task.展开更多
