Abstract
|
|
|
Objectives : The pathophysiology of ICH is not fully understood, therefore, the fundamental therapeutic strategies for ICH also not well inspected either. The genetic profile for the effect of Carthami Flos extract on cerebral hemorrhage in rat brain tissue was measured using microarray technique. Genes displaying expressional change on brain damage were selected and the functional analysis on these genes was conducted.
Methods : Rats were placed in a stereotaxic frame after intraperitoneal injection of chloralhydrate, and ICH was induced by injection of collagenase type IV and Carthami Flos extract was administered orally. The molecular profile of cerebral hemorrhage in rat brain tissue was measured using microarray technique to identify up- or down- regulated genes in brain tissue.
Results : Upon treatment with Carthami Flos extract on the rat having brain damage, many genes show expressional change. The pattern of gene expressional change can be classified into 8 classes in which two types of classes were composed of recovered genes from up or down-regulation by brain damage, respectively.
Conclusions : Further analysis using protein interaction database identified some key molecules that can be used for elucidation of therapeutical mechanism of Carthami Flos extract in future.
