验证理论

In this thesis, the theories and methods of GA are analyzed in detail , the trend of GA in recent times is briefly discussed. Because of the importance of image segmentation, two methods of color image segmentation based on GA are proposed. One is the surface of thresholds image segment method, the other is entropic threshold method. Two algorithms are realized through VC++ 6.0. After that, we compare the characteristics of two algorithms and prove that GA can be very well applied to solving image optimal problems.

In order to confirm this suspect, we choosed a cultured rat granulation tissue fibroblasts model in vitro and applied RT-PCR and cell-ELISA technology to detect the changes of firbroblasts intrinsic EGF, bFGF, TGFβ-1 with their receptors gene expressions and protein synthesises after stimulated by SP. Our purpose was to explore the possible effects and patterns imposed by SP on fibroblasts intrinsic growth factors and their receptors expressions, which maybe offer theoretical basis for promoting wound healing via improving nervous functions and regulating neuropeptides secretions.
