Background
Thrombosis is a major disorder which is an outcome of an imbalance in the
hemostatic system that develop undesirable blood clot and hinder blood
circulation.
Purpose
The current study was designed to verify the potential of aqueous methanolic
crude extract of
Asphodelus tenuifolius
Cav
.
(At.Cr), used traditionally as remedy in
circulatory problems.
Research Design
Antioxidant activity, FTIR, and HPLC analysis were performed.
In-vitro
clot lysis assay was performed on human blood
samples, and
in-vivo
acute pulmonary thromboembolism model
was developed by administering the mixture of collagen and epinephrine in
tail vein of mice. Carrageenan-induced thrombosis and
FeCl
3
-induced carotid arterial thrombosis models were developed
in rats.
Results
At.Cr demonstrated significant increase in lysis of human blood clot.
Bleeding and clotting times were increased dose-dependently. Lungs histology
showed clear alveolar spaces with decreased red blood cells congestion.
Reduction in infarcted tail length, augmentation in prothrombin time, and
activated partial thromboplastin time with decrease in platelet count were
observed. At.Cr also prolonged the arterial occlusion time and reduced the
weight of thrombus and TXB
2
levels dose-dependently.
Conclusions
The results demonstrated the antithrombotic and thrombolytic potential of
At.Cr due to activation of coagulation factors through extrinsic and
intrinsic pathways.
