The changes of white microthrombus and microvascular diameter in pia mater microvessel were observed by using cranial window method and closed microcirculation detection system, The concentration of Hcy was detected by high performance liquid, The level of von Willebrand factor, endothelin-1 (ET-1) were assayed by ELISA. The content of NO was measured by nitrate reduction method. Meanwhile, the relationship between the changes of microvascular diameter and blood concentration ET-1, NO was analyzed.

Three kinds of BCRC No.51534, 10322 and 10675 would be selected and acted as an experimental sample of Escherichia coli. Results shows that Escherichia coli of No.51534 will appear better performance because the maximum of open circuit voltage, closed current and power density are 1.01V, 22mA and 1342mW/m2, respectively. Concerning the effect of culture time with respect to different phase type on the electricity performance of MFCs, the time points on the intersection between lag phase and logarithmic phase, the middle of point of stationary phase for growth curve of Escherichia coli would appear a good performance of MFCs. In addition, the BCRC No. 51534 Escherichia coli possessing a better performance of MFCs than others would be suggested and applied to further studying. Comparison with the performance of MFCs with respect to electron mediator under different mole number, result shows that electron mediator of methylene blue with 4.63mM would appear a better electricity performance of MFCs than others. Concerning the different material of proton exchange membrane with PTFE-Nafion, Nafion 211, 212 and 117 with respect to the performance of MFCs, result shows that the Nafion 117 applied in MFCs will have a better performance of MFCs than other cases. Finally, the effect of molar concentration on the performance of MFCs would be expected at the studied cases of 0.4M, 0.2M, 0.1M and 0.05M respectively for cathode oxidant, result shows that a good performance of MFCs will happen at the condition of 0.2M. Those observations will be useful to improvement of MFCs in the further study.
