Protective Effect of Artemisinin on Mice with Systemic Inflammatory Response Syndrome
To study the protective effect and mechanism of artemisinin on systemic inflammatory response syndrome (SIRS)mice using endotoxin (LPS)-induced SIRS mouse model.
Method
2
Male BALB/c mice aged 5-7 weeks were randomly divided into normal group, LPS model group, low, medium and high-dose artemisinin groups (25, 50, 100 mg·kg
-1
) and ibuprofen group (39 mg·kg
-1
). LPS (10 mg·kg
-1
) was intraperitoneally injected at the 7
th
day after the prophylaxis. According to the SIRS clinical diagnostic criteria, the respiratory rate, rectal temperature, lung index, spleen index, glycolipid metabolism, brain tissue inflammatory factors, and phosphorylation of lung tissue inflammation-related proteins were measured.
Result
2
Intraperitoneal injection of LPS significantly reduced the respiratory rate of mice (
0.05), percentage of monocytes decreased significantly (
P
<
0.01), thrombocyte decreased (
P
<
0.01), platelet specific ratio decreased (
P
<
0.01), total cholesterol content in plasma decreased (
P
<
0.01), plasma glucose content decreased (
P
<
0.01). The expression of interleukin-1
β
increased in hippocampus and cortex of brain tissue (
P
<
0.01), and the secretion of tumor necrosis factor-
α
increased in hippocampus and cortex of brain tissue (
P
<
0.01). The expression of phosphorylated protein STAT1 was increased (
P
<
0.01), and the expression of phosphorylated protein c-Jun was increased (
P
<
0.01). After the administration of artemisinin, the body temperature and the respiratory rate of mice induced by LPS were significantly increased, the pathological changes of various organs induced by LPS were alleviated, the hypoglycemia induced by LPS was significantly increased (
P
<
0.05), the levels of inflammatory factors in hippocampus and cortex was significantly reduced, and the expressions of phosphorylated proteins STAT1 and c-Jun in lung tissue were significantly reduced (
P
<
0.05,
P
<
0.01).
Conclusion
2
Artemisinin has a significantly protective effect on SIRS mice induced by intraperitoneal injection of LPS possibly by reducing the secretion of inflammatory factors TNF-
α
and IL-1
β
.
