Effects of Shenfuhuang Formula (参附黄配方) on Oxidative Damage of Cerebral Cortex in Septic Mice
C57BL/6 mice were randomly divided into sham operation group, sepsis group and SF group, with 26 mice in each group. Cecal ligation and perforation (CLP) was used to induce sepsis model in the sepsis group and SF group. After modeling, the SF group was given 5.0 g/(kg·d) of SF by gavage, while the sepsis group and the sham operation group were given 0.5 mL of normal saline by gavage, both for three days. Seventy-two hours after modeling, Nissl staining was used to observe the changes in the number of neurons in the perfrontal cortex of the brain, and dihydroethidium staining was used to detect active oxygen content in the cerebral cortex tissue; 8-Hydroxydeoxyguanosine (8-OHdG) immunofluorescence staining was used to evaluate the oxidative DNA damage in cerebral cortex.
Results
2
Compared to those of the sham operation group, the number of neurons in the prefrontal cortex of the sepsis group were reduced, while the content of reactive oxygen species increased, and the expression of 8-OHdG increased (
P
<0.05). Compared to those of the sepsis group, the number of neurons in the SF group increased, while the content of reactive oxygen species were inhibited, and the expression of 8-OHdG decreased (
P
<0.05).
Conclusion
2
SF has a protective effect on the damage of prefrontal cortex neurons in CLP mice, and its mechanism may be related to the reduction of oxidative stress and oxidative DNA damage.
