Abstract

To investigate the effects of different doses of hydrocortisone (HC) on the disorder of coagulation in rats at early stage of septic shock. The model of early septic shock accompanied by the disorder of coagulation in rats was set up by bolus injection of lipopolysaccharide (LPS) at 25 mg/kg through right femoral vein. Forty male Wistar rats were randomly divided into the following 5 groups: normal control (LPS and HC were substituted by same volume of normal saline solution), shock group (HC was substituted by same volume of normal saline), high-dose HC (HD group, HC 100 mg/kg), medium-dose HC (MD group, HC 50 mg/kg) and low-dose HC (LD group, HC 5 mg/kg). Four hours after the HC treatment, the blood specimens were collected for the count of blood platelet (PLT), the activity of antithrombin III (ATIII), the content of D-dimer and von Willebrand factor (vWF). The count of PLT (x 10(9)/L) and the activities of ATIII (%) in shock group (586.00 +/- 71.179 and 50.600 +/- 19.248) were significantly lower than that in normal control group (1012.600 +/- 20.852 and 89.200 +/- 12.109), and the level of D-dimer (microg/dl) and vWF (%) in LPS group (1.680 +/- 0.999 and 7.288 +/- 0.652) as significantly higher than that in normal control ...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.
