This study evaluated the removal of viable Cryptosporidium parvum oocysts and changes in zeta potential during alum coagulation and sedimentation. Experiments were designed to evaluate oocyst removal and oocyst zeta potential at three initial dissolved organic carbon (DOC) concentrations and a wide range of alum doses and coagulation pH values. The study showed that changes in the initial DOC c...

The three factors which catalyse thrombus formation and intravascular coagulation are changes in the rate of blood flow, changes in the vessel wall, and changes in the nature of the blood. These factors, which were enumerated over a hundred years ago by Rudolph Virchow,47 are still our main guide lines. The various causes of changes in blood flow are well known. The antithrombotic properties of...

The process of blood coagulation in mammals is complicated, and involves the interaction of more than a dozen coagulation factors as well as a number of proteins from the kininkallikrein system and protein inhibitors. Attempts to model coagulation mathematically have previously focused on a smaller subset of interactions, perhaps one of the pathways or just a portion of one of them (cf. [1],[2]...

The integral changes of coagulation and fibrinolysis, and their relationships with inflammation in patients with Takayasu arteritis (TA) remain undetermined. The purpose of this study was to analyze the changes of coagulation and fibrinolysis process in patients with TA by thrombelastography (TEG).A total of 127 patients with TA and 55 healthy controls were enrolled. Patients with TA were group...

The studies on the morphology of lesions produced and the blood coagulation disturbances after Russell viper envenomation were studied in guinea pigs. The study showed very little morphological changes but the coagulation studies revealed disturbances in coagulation mechanism. The exact pathological process operating in Russell viper emvenomation needs further studies including the histochemica...

The present study was performed to detect the usefulness of coagulation parameters that helps in the diagnosing the severity of changes associated with heat stroke. Twenty five previously healthy dogs with the history of epistaxis, hyperthermia and dyspnea after exposure to high environmental temperature were selected and subjected to detailed clinical examination, physical examination, laborat...

Discussion: A large part of both clinical and subclinical lesions found in our daily work are benign and correspond with fibrocystic changes (FCC). This entity is complex and part exhibit traits that define characteristically in MRI and diagnose correctly, but there is another small group of changes that can take the image aspect of cancer. From a complex case, we review the main aspects of the...

Thyroid dysfunction is associated with changes in coagulation. The aim of our study was to gain more insight into the role of thyroid hormone in coagulation control. C57Black/6J mice received a low-iodine diet and drinking water supplemented with perchlorate to suppress endogenous triiodothyronine (T3) and thyroxine (T4) production. Under these conditions, the impact of exogenous T3 on plasma c...

conclusions our study showed that desmopressin could not reduce the amount of blood loss after cabg. also, desmopressin did not have a significant effect on coagulation status. therefore, based on the results of our study, it seems that the use of this medication cannot be a helpful for patients with any indication for cabg. background coronary artery bypass grafting (cabg) is a common surgical...
