RESULTS: Totally 57 rats enrolled in this study, all animals completed Hot pain allergic symptom could not be observed on rats in experimental group during the whole experimental process, but continuously appeared in discharge percentage of nerve fibers at the central end of experimental rat sciatic nerve was remarkably lower than that of the control group 6.79％Sympathetic postganglion nerve fiber budding was not obvious in the slices of entire L4-5 dorsal root neuroganglion of injury side in 6 experimental rats,and basket-shaped cell could not be observed, but sympathetic postganglion nerve fiber budding was obvious in 2 rats in control groups with altogether 41 basket-shaped cells observed.

电生理实验：实验组大鼠坐骨神经中枢端的神经纤维自发放电百分数显著低于对照组(6.79％，46 7％)。③背根神经节切片荧光染色结果：实验组6只大鼠损伤侧L4-5的全部背根神经节切片中看不到明显的交感节后神经纤维芽生，没找到篮状细胞，而在对照组2只大鼠损伤侧L4-5的全部背根神经节切片中可看到明显的交感节后神经纤维芽生，共找到篮状细胞41只。

Three kinds of hydrophytes, Veliveria zizanioides Nash, Eichhornia crassipes, and Oenanthe javanica DC. were used to investigate enrichment ability of nitrogen and phosphor at the different TN levels with TP constant. It revealed the absorption ability of aquatic plants and purification ability of aquatic macrophytes-rhizosphere microorganisms system respectively in aquatic macrophytes-microorganism system for water purification.

研究了不同TN浓度下香根草、水葫芦、水芹等水生植物－微生物系统富集N、P的能力，揭示了水生植物－微生物系统中水生植物的吸收作用和根际微生物系统对净化水质的作用，对水生植物根际微生物系统相应微生物的数量做了定量的统计。

This report presents 2 cases of inadvertent injection of sodium hypochlorite into the periradicular tissue because of apical constriction destruction and canal perforation. Acute severe pain, gingival swelling, cellulites, and even parathesis over the circumscribed region of the upper lip were noted.
