Snake venoms contain a rich variety of factors which affect blood coagulation. There have been few reports on the anticoagulant activity of the venom of different cobras, but no such observations have been made on the Iranian cobra, although a procoagulant factor has been described. In this study an anticoagulant factor has been purified from the venom of Naja naja oxiana using gel filtrat...

BACKGROUND/AIM Radiotherapy is required to overcome pain and to promote recalcification in multiple myeloma (MM) patients. The aim of our prospective study was to evaluate the impact of one fraction of 8 Gy regimen in palliative treatment of MM. MATERIALS AND METHODS Forty-six patients with MM and painful bone destructions were treated by 8 Gy single fraction regimen. The visual analog scale ...
The anticoagulative principles in Paeoniae Radix, which is one of the most important herbs and is used commonly for the treatment of female diseases in traditional oriental medicine, were investigated. In this study the measurement of plasma recalcification time in mice was found to be useful for following the anticoagulative activity of the material, and the active principles were isolated fro...
We compared sulfated galactans (SGs) from two species of red algae using specific coagulation assays and experimental models of thrombosis. These polysaccharides have an identical saccharide structure and the same size chain, but with slight differences in their sulfation patterns. As a consequence of these differences, the two SGs differ in their anticoagulant and venous antithrombotic activit...
Variations of the partial thromboplastin time (PTT) were tested to determine the best screening method for detection of inhibitors of factor VIII. Variables tested included the duration of preincubation of a mixture of patient plasma and factor VIII source (normal plasma), the ratio of the patient plasma to the normal plasma, and the duration of incubation of the normal plasma-patient plasma mi...
In order to determine their value for estimating the heparin concentration in plasma, we established the relationship between test result and heparin concentration in plasma from various individuals, for five assays used with heparin treatment. Only assays which can be carried out routinely in clinical laboratories were considered. The thrombin time and the whole blood recalcification time give...
A decrease in light transmittance before clot formation, manifesting as a biphasic waveform (BPW) pattern in coagulation assays, was previously correlated with the onset of disseminated intravascular coagulation (DIC). In this study of 1187 consecutive admissions to the intensive care unit, the degree of this change on admission predicts DIC better than D-dimer measurements. Additionally, the B...
