Ligusticum wallichii Extract Inhibited the Expression of IL-1β after AMI in Rats

الملخص EN

This study investigated the effects of Ligusticum wallichii on IL-1β expression in myocardium and central nervous system after AMI.

AMI rat was administrated with Ligusticum wallichii extract.

A series of assays were used to detect the effects of Ligusticum wallichii extract on infarct size, left ventricular ejection fraction, expression of TLR-4, NF-κB, and IL-1β in myocardium, IL-1β expression in serum and hypothalamus, and NPY expression in hypothalamus.

We observed that Ligusticum wallichii extract improved the left ventricular ejection fraction and reduced infarct area enlargement after AMI, by inhibiting the expression of IL-1β in myocardium, serum, and hypothalamus.

Ligusticum wallichii extract reduced the expression of IL-1β in myocardium by regulating TLR4-NF-κB signaling pathway and inhibited IL-1β in hypothalamus by regulating NPY mRNA expression.
