Enhanced Glu activity aggravated neuronic damage through many aspects.

Glu在CNS活性增强通过诸多环节加重NC的损伤。

Glu could induce disturbances of SS-GH axis and neuronic homeostasis by influencing the secretion of SS and GH, and aggravate CGS by exciting paraventricular nuclei .

与此同时Glu通过影响SS和GH的分泌，使SS—GH轴的紊乱，造成NC内环境的紊乱，并通过中枢室旁核机制具有加重CGS的病理作用。

During rat's intracerebral hemorrhage processes, Glu is over released and accumulated in hypothalamus and brain tissues surrounding hematoma, which could induce the opening of 〓 and 〓 ion channels, and evoke cellular-toxic edema. Meanwhile it may also evoke 〓 influx into neurons. It is this 〓 influx that may activate phosphase and proteinase, disrupt protein and cellular skeletons, and further aggravate neuronic damage.

大鼠脑出血过程中Glu在下丘脑及血肿周边脑组织的大量释放和积聚，通过其开放〓离子通道，造成细胞毒性水肿，使〓内流激活磷酸酶和蛋白酶，破坏蛋白质和细胞骨架，加重NC的损伤过程。

The imbalances of SS-GH axis regulation, the regulator disorders of GluR, GluR affinity and Glu, SS-MTL axis, SS- Gastrin axis etc. showed obvious perturbations of internal circumstance in CNS and local Gastroenteral tissues. It is one of the important causes that intracerebral hemorrhage may exist extensively in range and seriously in degree, and may evoke irreversible neuronic damage.

脑出血过程中SS—GH轴调控异常，GluR及其亲合力与Glu的调节障碍以及SS—MTL，SS-Gastrin的相互调节失衡，充分表明中枢与胃肠局部均存在明显的内环境紊乱，是脑出血损伤范围广，程度严重，促使NC不可逆性损害的重要原因之一。

Since there exists some disadvantages such as poor mechanic properties and much higher burning rate pressure exponents (?1) in the fundamental formulations, this work is devoted to the improvements of combustion characteristics and mechanic properties of LOVA propellants. The effects of the crystal shape, size and contents of nitroamine particles, the types of binder, plasticizer and surface-active agents and the contents of NC on combustion performance are studied by closed bomb tests. In the mechanic properties tests, the effects of the types of binders, plasticizers and solid fillers, the interaction between binders and solid fillers and technological procedures on propellant mechanic properties are researched.
