Seaweed-derived heparin-like substances such as fucoidan have been extensively studied in vitro as potential blood anticoagulants. However, there have been no human studies investigating the anticoagulant activity of fucoidan when administered orally. This pilot clinical trial was aimed to assess the safety and clinical effects of fucoidan ingestion on hemostasis as well as study its in-vitro a...
of treatment and also later, when the patient is apparently adequately treated according to the prothrombin ratio. It appears that patients with venous lesions require more anticoagulant to produce the same partial thromboplastin clottingtime than do patients with arterial lesions, and this may have a bearing on relapses and further thromboses. Examination of results from 21 patients when they ...
به منظور به وجود آمدن مبنایی جهت مطالعه وضعیت انعقادی گوسفند که امروزه به عنوان مدل ، در تحقیقات تجربی مورد قبول قرار گرفته است،این مطالعه بر روی 40 رأس گوسفندان دانشگاه شهرکرد(نژاد محلی چالشتری) انجام گرفت. در طی این مطالعه مقادیر زمان سیلان(bleeding time ,bt) زمان انعقاد (clotting time , ct) خون تازه روی لام،زمان نسبی ترومبوپلاستین(partial thromboplastin time ,ptt) و زمان پروترومبین (prothrom...
The partial thromboplastin time test provides a convenient and sensitive screening procedure for deficiencies of thromboplastic factors, especially factors VIII and IX. The test is carried out after preincubating the plasma for 10 minutes with kaolin, and Inosithin is used as a platelet substitute. The ;normal range' of the test has been estimated in terms of the differences encountered between...
BACKGROUND Routine repeat testing of critical laboratory values is very common these days to increase their accuracy and to avoid reporting false or infeasible results. We figure that repeat testing of critical laboratory values has any benefits or not. METHODS We examined 2233 repeated critical laboratory values in 13 different hematology and chemistry tests including: hemoglobin, white bloo...
The tissue thromboplastin activity of porcine lung was separated from an aqueous tissue extract by differential centrifugation. Repeated suspension and sedimentation yielded a thromboplastin preparation free of soluble protein. The most effective delipidation of the lyophilized preparation with minimum denaturation of the protein moiety of thromboplastin was achieved using n-heptane/n-butanol e...
BACKGROUND The activated partial thromboplastin time (APTT) is used to adjust heparin sodium dosage. However, warfarin sodium is often administered concomitantly with heparin and may also affect the APTT and, therefore, heparin dose. We performed a prospective cohort study to quantify the effect of warfarin on the APTT in patients who are being treated with heparin. METHODS Serial assays of A...
