UNASSIGNED
Protosappanin A (PrA) is an effective and major ingredient of Caesalpinia sappan L. The current study was aimed to explore the effect of PrA on atherosclerosis (AS).
UNASSIGNED
Firstly, the experimental model of AS was established in rabbits by two-month feeding of high fat diet. Then,

Protosappanin A (PrA), an immunosuppressive ingredient of the medicinal herb Caesalpinia sappan L, prolongs heart allograft survival in rats, possibly by impairing the function of antigen-presenting cells (APCs). We examined the effects of PrA on the maturation and function of dendritic cells (DCs),
