| Outline of Final Research Achievements |
To study the mechanism of SLF using the change of mitochondrial (Mito) respiratory function in SLF model. Male C57bl/6J mice were divided into two groups, one was CLP group induce sepsis and the other was Sham group. Isolated liver mito were exposed to continuous infusions of Ca2+. Monitoring of extra-mito Ca2+ and mito respiration provided a quantitative assay for mPT sensitivity by determining CRC and mito swelling%. And we investigated the role of different uncoupler and respiratory complex to evaluate maximal respiratory activity of mito and ETS. No significant changes in CRC, Swelling%, a value, CS and RCR of CLP were detected compared to Sham. The CLP tended to be slightly high in Swelling% rate and a value rate in CLP /Sham. FCCP and Rote value of CLP were lower compared to Sham significantly in SUIT protocol. There was little change in FCCP/Rot between both CLP and Sham. These results suggested the possibility of the obstacle of the ETS activity around complex I in CLP.
