a dry syringe. 2 cc. of blood was put into a sterile empty penicillin vial to which .5 cc. of 3.8% sodium citrate solution had already been added. It was immediately mixed thoroughly by rotating the vial. The mixture was then drawn up into a Westergren's standard tube up to zero mark?which is exactly 200 m.m. from the tip. The tube was set up absolutely in a vertical position in a non-vibrating...

Background & Aim:The main aim of this study was stabilizing D. Sophia beverage and reduce its sedimentation rate. Experimental: Xanthan and Carboxy methyl cellulose gums have been used in three levels (0.05, .01 and .02 gr/lit) and mixture of Guar-xanthan and carboxymethyl cellulose (each .1 g/l) and extracted dried gum from D. Sophia in (1, 2 an...

The term high-rate sedimentation used here refers to the use of shallow gravitational settlers with detention periods of not more than 15 min to achieve comparable or better settling efficiencies normally obtained in conventional rectangular settling tanks having detention periods of usually more than 2 hr. The settlers can be rectangular, circular, or any other convenient shape. They can be ei...

background: evidence is accumulating that venous thromboembolism is not limited to coagulation system and immune system seems to be involved in formation and resolution of thrombus. some studies have demonstrated the role of inflammatory factors in deep venous thrombosis (dvt) of limbs; however, there has not been such study in the patients with cerebral venous sinus thrombosis (cvst). the purp...
