Methods 20 rats were randomly divided into A, B, C, D and E group. The models of cerebral anoxia in group A and C were made by hypopiesia and hypoxia, and the models of hypoxia-reoxgenation were made in group B and D. 24h and 1h before establishment of models, ginsenoside Rb3 was injected peritoneally in rats of group C and D, respectively. The number and form of GABA-like immunoreactive neurons in hippocampus CA1 area of rats after brain hypoxia-reoxgenation were investigated with immunohistochemistry.

In the two test sites, the soil water movement numerical models of vertical-one-dimension and cross section two-dimension have been established with the softwarer Vadose/W and self-programming code, of which the advantage is that it can deals with lower boundary and the upper boundary (such as meteorologic, vegetational, etc) conditions in convenience. The fitting between the model and observation data from sites indicates that the models are relatively high precision. So the models can be used to study problems such as soil evaporation, infiltration to recharge groundwater and so on under various conditions.
