Abstract

Thrombomodulin (TM) is down-regulated from the vascular endothelial surfaces and corresponds to disturbed dermal blood flow and microthrombus formation in the ischaemic skin flap. We examined the therapeutic potential of simvastatin which up-regulates endothelial cell TM expression and activity in the dorsal ischaemic skin flap model. The study was carried out on 30 rats, divided into three groups. Group 1 was treated with simvastatin at a dose of 5mgkg(-1) day(-1) by intraperitoneal injection. Group 2 was treated with 1mgkg(-1) day(-1) with a phosphate-buffered saline for 7 days. Group 3 was the control group. Tissue blood flow, vascularisation and the survival rate of the skin flaps from each group were compared. The mean surviving area of group 1 was higher than groups 2 and 3 (p<0.05). The blood flow change rate did not decrease in the treatment group in contrast to the control groups at 3cm and 5cm (p<0.05). Microangiography demonstrated decreased flap vascularity in groups 2 and 3. There was no evidence of necrosis or positive peroxidase staining for TM in group 1 at 3cm and 5cm., although it was negative in groups 2 and 3. In this study, it was demonstrated that simvastatin prevented shedding of endothelial TM and contri...Continue Reading

Blood Clotting Disorders

Thrombophilia includes conditions with increased tendency for excessive blood clotting. Blood clotting occurs when the body has insufficient amounts of specialized proteins that make blood clot and stop bleeding. Here is the latest research on blood clotting disorders.
