Objective： To evaluate the effects of botulinum toxin type A （BTX-A） on mandible skeletal development by inducing muscle hypofunction. Methods： Four-week-old Sprague-Dawley rats （n=60） were divided into three groups： Group 1 animals served as controls and were injected with saline; Group 2 animals were injected unilaterally with BTX-A （the contralateral side was injected with saline）; and Group 3 animals were injected bilaterally with BTX-A. In Group 2, the saline-injected side was designated the control side （Group 2-1）, whereas the BTX-A-injected side was designated the experimental side （Group 2-2）. After four weeks, the animals were sacrificed, dry skulls were prepared, and mandibles were measured. Results： In the unilateral group, the experimental side （Group 2-2） had reduced di- mensions for all mandible measurements compared with the control side （Group 2-1）, suggesting a local effect of BTX-A on mandible growth, likely due to muscle reduction. Conclusions： Localized BTX-A injection induced a change in craniofacial growth, and the skeletal effect was unilateral despite both sides of the mandible functioning as one unit.

The nitrogen changes and the nitrogen mass balance in a free water surface flow constructed wetland （CW） using the four-year monitoring data from 2008 to 2012 were estimated. The CW was composed of six cells in series that include the first settling basin （Cell 1）, aeration pond （Cell 2）, deep marsh （Cell 3）, shallow marsh （Cell 4）, deep marsh （Cell 5） and final settling basin （Cell 6）. Analysis revealed that the NH4＋-N concentration decreased because of ammonification which was then followed by nitrification. The NO4＋-N and NO4＋-N were also further reduced by means of microbial activities and plant uptake during photosynthesis. The average nitrogen concentration at the influent was 37,819 kg/year and approximately 45% of that amount exited the CW in the effluent. The denitrification amounted to 34% of the net nitrogen input, whereas the accretion of sediment was only 7%. The biomass uptake of plants was able to retain only 1% of total nitrogen load. In order to improve the nutrient removal by plant uptake, plant coverage in four cells （i.e., Cells 1, 3, 4 and 5） could be increased.
