Theoptimal conditions were as follows: amidulin 1.25%,CaCO_3 0.05%, yeast0.6%,NaC1 0.7%,KH2PO4 0.3%. The stability of antagonistic substance produced by Q6 was studied. Theactivity of the inhibitive substance was influenced when time and temperaturewaxing. In 100℃for 30 minutes,the inhibitive zone diminished distinctly, but thesubstance still had inhibitive effect on the pathgen. In pH 3.0~above 9.5 forovernight or treated by Proteinase K, the inhibitive zone is not changed.

The growth of H. fusiformis was determined by weighting the fresh algae every two days and the photosynthetic oxygen evolution was assayed by a Clark-type oxygen electrode. To determine the contents of chlorophyll a and UV-absorbing compounds, methanol extracts from H. fusiformis were scanned from 250 to 750 nm. The concentration of chlorophyll a was calculated using the equation of Porra and the contents of UVAC per fresh mass were estimated by determining the ratio of UVAC to chlorophyll a according to Dunlap et al and multiplying the ratio of chlorophyll a content to fresh weight of the sample used.
羊栖菜的生长是通过每两天测量一次藻体的湿重来测定的,光合放氧是用Clark型氧电极测定的,为了测定藻体叶绿素a和紫外吸收物质的含量,从250 nm到750 nm对羊栖菜的甲醇提取液进行扫描,叶绿素a的浓度用Porra的公式计算,紫外吸收物质的计算是根据Dunlap的方法先计算紫外吸收物质和叶绿素a的比率,然后乘以每单位藻体叶绿素a的含量。

During the early growth stage of seedlings, basal stem diameter and paripinnate number were decreased with the increasing of shade, taproot length, root : shoot ratio, total dry weight and leaf area per seedling were maximal under 37.3% NS, specific leaf area was increased with the increasing of shade, but the relative growth rate was declined. Seedlings grew fastest under 0.6% NS, suggesting that nutrients stored in seeds played an important role at the early growth stage. The treatment of 37.3% NS was best for established seedlings in seedling height, basal stem diameter, paripinnate number, rachis length, the maximum sub-leaflet number of individual paripinnate, leaf area per seedling, relative growth rate and net assimilation rate. Light intensity was positively correlated to total dry weight, and negatively to specific leaf area. The maximum of SLA was observed under 15.5% NS.
生长早期的幼苗基径和复叶数随遮荫程度的增加而降低;主根长、根冠比、总干重和单株叶面积均以37.3% NS处理最大;比叶面积随遮荫程度的增加而增大,而相对生长率则降低;幼苗株高在0.6% NS下增长最快,表明种子中贮藏的营养物质对幼苗的早期生长可能具有重要作用。37.3% NS处理对定居后绒毛番龙眼幼苗的生长最有利,幼苗的株高、基径、复叶数、叶轴长、复叶最多小叶数、单株叶面积、相对生长率和净同化率均在37.3% NS处理下获得最大增长;幼苗总干重随光照强度的减弱而降低;比叶面积在15.5% NS处理时最大。

It has been proved by previous studies that peripheral nerve injury can induce a series of changes of expression of some neural active material and their receptors either in the somata or in the terminals of the damaged primary afferent neurons and motoneurons. These changes may reflect a re-ordering of metabolic priorities so that the synthesis of trophic factors or growth-associated proteins augmented while that of neurotransmitter-related proteins decreased.
以往的研究表明,周围神经损伤能够引起受损神经元(包括初级传入神经元和运动神经元)的胞体或终末内某些神经活性物质及其受体的表达发生一系列变化,其中与神经生长和营养有关的物质常发生上调,而与神经传递有关的物质则发生下调;与此同时,受损神经元的周围常伴随发生胶质反应及神经胶质增生等变化。
