We evaluated the effectiveness of a novel hemostatic powder called Tranexamic Acid-loaded Porous Starch (TAPS) developed recently on blood clotting activity and hemostasis. The effectiveness of TAPS was evaluated by comparing hemostatic properties with those of Quick-acting Styptic Powder (QSP) and Compound Microporous Polysaccharide Haemostatic powder (CMPHP). The blood clotting activities of human blood were analyzed by thromboela-stogram (TEG) assays in vitro. The hemostatic effectiveness in vivo was evaluated using a rat model with hepatic traumatic hemorrhage...

BACKGROUND AND OBJECTIVES: Extracorporeal membrane oxygenation (ECMO) is a method of life support for either isolated cardiac failure or respiratory failure, with or without cardiac failure. When used for hemodynamic support, the ECMO circuit presents a non-endothelialized, artificial surface to blood inciting an inflammatory response which activates haemostatic pathways. Anticoagulation may complicate a pre-existing coagulopathy and/or inadequate surgical hemostasis of varying severity...

Energy based devices (EBD) have been developed, implemented and increasingly applied in thyroid surgery because they can provide a combined dissection and haemostatic effect. In particular, advantages of EBD have been described in terms of efficacious haemostasis, reduction of procedure-associated time, reduced incision length, less operative blood loss and transfusion need, decreased postoperative drain, pain and hospital stay. In addition, EBD are essential for endoscopic procedures. On the contrary, a potential drawback is the increased health care costs...

The work is aimed to an assessment of the correlation between of autonomic nervous system tone and the level of reactivity of the students' cardiovascular system and hemostasis system under examination stress. It was found that the students under exam stress are characterized with high values of respiration rate and with lower ones of tidal volume. The value of respiratory minute volume decreases in male students due to the bronchoconstrictor effects of stress at the tracheobronchial tree. This finding confirms a statistically significant reduction in the flow of small, medium and large bronchi, indicating an increased parasympathetic nervous system tone...

INTRODUCTION: General adaptation syndrome (GAS), the basis of the development of which is stress phenomenon, is an essential component of the pathogenesis of many diseases and syndromes. However, the patho genesis of GAS hitherto is considered exclusively from the endocrinological viewpoint. This relates primarily to the initial phase of the GAS, a clinical model for the study of which may be psycho-emotional stress (PES), which we studied using three groups of volunteers. METHODS: The first one consists of 25 students who were waiting for unaccustomed physical activity (17 men) and play debut on the stage (8 women)...

To develop biocompatible composite microspheres for novel hemostatic use, we designed and prepared a novel biomaterial, composite microspheres consisting of carboxymethyl chitosan, sodium alginate, and collagen (CSCM). The ultra-structure of CSCM was investigated by scanning electron microscopy assay. In hemostatic function experiment, it was found that CSCM could facilitate platelet adherence, platelet aggregation, and platelet activation in vitro. Besides, the maximum swelling of CSCM submerged in PBS for 50 min was over 300% of that exhibited by commercial hemostatic compound microporous polysaccharide haemostatic powder (CMPHP)...

Multiple sclerosis (MS) is the autoimmune disease of the central nervous system with complex pathogenesis, different clinical courses and recurrent neurological relapses and/or progression. Despite various scientific papers that focused on early stage of MS, our study targets selective group of late stage secondary progressive MS patients. The presented work is concerned with the reactivity of blood platelets in primary hemostasis in SP MS patients. 50 SP MS patients and 50 healthy volunteers (never diagnosed with MS or other chronic diseases) were examined to evaluate the biological activity of blood platelets (adhesion, aggregation), especially their response to the most important physiological agonists (thrombin, ADP, and collagen) and the effect of oxidative stress on platelet activity...
