Many variations of the method have been developed.

Familial overexpression of beta antithrombin caused by an Asn135Thr substitution. (1/74)

We have investigated the basis of antithrombin deficiency in an asymptomatic individual (and family) with borderline levels (approximately 70% antigen and activity) of antithrombin. Direct sequencing of amplified DNA showed a mutation in codon 135, AAC to ACC, predicting a heterozygous Asn135Thr substitution. This substitution alters the predicted consensus sequence for glycosylation, Asn-X-Ser, adjacent to the heparin interaction site of antithrombin. The antithrombin isolated from plasma of the proband by heparin-Sepharose chromatography contained amounts of beta antithrombin (the very high affinity fraction) greatly increased (approximately 20% to 30% of total) above the trace levels found in normals. Expression of the residue 135 variant in both a cell-free system and COS-7 cells confirmed altered glycosylation arising as a consequence of the mutation. Wild-type and variant protein were translated and exported from COS-7 cells with apparently equal efficiency, in contrast to the reduced level of variant observed in plasma of the affected individual. This case represents a novel cause of antithrombin deficiency, removal of glycosylation concensus sequence, and highlights the potentially important role of beta antithrombin in regulating coagulation.  (+info)

Plasma antithrombin III deficiency in ischaemic stroke in the young. (2/74)

A deficiency of plasma antithrombin III has been identified as a potential risk factor for thrombosis. In a pilot study of 56 patients aged less than 40 years who presented with ischaemic stroke of unknown etiology, we detected only one case of plasma antithrombin III deficiency. Antithrombin III activity was estimated by a chromogenic assay. Hence, antithrombin III deficiency, though rare, should be considered while evaluating young patients with stroke of unknown etiology.  (+info)

Enhancement of heparin cofactor II anticoagulant activity. (3/74)

Heparin cofactor II (HCII) is a serpin whose thrombin inhibition activity is accelerated by glycosaminoglycans. We describe the novel properties of a carboxyl-terminal histidine-tagged recombinant HCII (rHCII-CHis(6)). Thrombin inhibition by rHCII-CHis(6) was increased >2-fold at approximately 5 microgram/ml heparin compared with wild-type recombinant HCII (wt-rHCII) at 50-100 microgram/ml heparin. Enhanced activity of rHCII-CHis(6) was reversed by treatment with carboxypeptidase A. We assessed the role of the HCII acidic domain by constructing amino-terminal deletion mutants (Delta1-52, Delta1-68, and Delta1-75) in wt-rHCII and rHCII-CHis(6). Without glycosaminoglycan, unlike wt-rHCII deletion mutants, the rHCII-CHis(6) deletion mutants were less active compared with full-length rHCII-CHis(6). With glycosaminoglycans, Delta1-68 and Delta1-75 rHCIIs were all less active. We assessed the character of the tag by comparing rHCII-CHis(6), rHCII-CAla(6), and rHCII-CLys(6) to wt-rHCII. Only rHCII-CHis(6) had increased activity with heparin, whereas all three mutants have increased heparin binding. We generated a carboxyl-terminal histidine-tagged recombinant antithrombin III to study the tag on another serpin. Interestingly, this mutant antithrombin III had reduced heparin cofactor activity compared with wild-type protein. In a plasma-based assay, the glycosaminoglycan-dependent inhibition of thrombin by rHCII-CHis(6) was significantly greater compared with wt-rHCII. Thus, HCII variants with increased function, such as rHCII-CHis(6), may offer novel reagents for clinical application.  (+info)

The prevalence of hereditary thrombophilia in the Trakya region of Turkey. (4/74)

The prevalences of deficiencies in antithrombin III (AT III), protein C (PC), protein S (PS) and in the activated protein C (APC) resistance in the thrombotic population of the Trakya region, Turkey were investigated. 37 patients with venous thrombosis (VT) and 17 patients with arterial thrombosis (ArT) were included in this study. The mean ages of the patients with VT and ArT were 46 years (range 20-70) and 38 years (range 32-40), respectively. The activity of AT III was measured by commercially available immuno-turbidimetric assay. The activities of PC and PS were determined by coagulometric assay. The APC resistance was measured using a modified APTT-based clotting assay. Among the VT patients, there were 2 cases (5.4%) with AT III, 5 (13.51%) with PC deficiency, 5 (13.51%) with PS deficiency and 2 (5.4%) with APC resistance. In the ArT patient group, there was 1 patient (5.88%) with AT III, 3 (17.64%) with PC deficiency, 1 (5.88%) with PS deficiency and no APC resistant patients, while there was one (2.08%) with PC deficiency and one (2.08%) with APC resistance in the control group (49 persons, mean age 41 years). The relative risk of thrombosis (odds ratio) was 1.7 in the deficiency of PC and 5.6 in the deficiency of PS. The data presented suggests that the prevalences of AT III, PC and PS deficiencies causing thrombophilia in the Trakya region of Turkey are higher than in other reported studies while the APC resistance is lower than in others. Further studies including more patients would be required to clarify these discrepancies.  (+info)

Complete antithrombin deficiency in mice results in embryonic lethality. (5/74)

Antithrombin is a plasma protease inhibitor that inhibits thrombin and contributes to the maintenance of blood fluidity. Using targeted gene disruption, we investigated the role of antithrombin in embryogenesis. Mating mice heterozygous for antithrombin gene (ATIII) disruption, ATIII(+/-), yielded the expected Mendelian distribution of genotypes until 14.5 gestational days (gd). However, approximately 70% of the ATIII(-/-) embryos at 15.5 gd and 100% at 16.5 gd had died and showed extensive subcutaneous hemorrhage. Histological examination of those embryos revealed extensive fibrin(ogen) deposition in the myocardium and liver, but not in the brain or lung. Furthermore, no apparent fibrin(ogen) deposition was detected in the extensive hemorrhagic region, suggesting that fibrinogen might be decreased due to consumptive coagulopathy and/or liver dysfunction. These findings suggest that antithrombin is essential for embryonic survival and that it plays an important role in regulation of blood coagulation in the myocardium and liver.  (+info)

Inherited thrombophilia in ischemic stroke and its pathogenic subtypes. (6/74)

BACKGROUND AND PURPOSE: One or more of the inherited thrombophilias may be causal risk factor for a proportion of ischemic strokes, but few studies have addressed this association or the association between thrombophilia and pathogenic subtypes of stroke. METHODS: We conducted a case-control study of 219 hospital cases with a first-ever ischemic stroke and 205 randomly selected community control subjects stratified by age, sex, and postal code. With the use of established criteria, cases of stroke were classified by pathogenic subtype in a blinded fashion. The prevalence of conventional vascular risk factors; fasting plasma levels of protein C, protein S, antithrombin III; and genetic tests for the factor V Leiden and the prothrombin 20210A mutation were determined in cases and control subjects. RESULTS: The prevalence of any thrombophilia was 14.7% (95% CI, 9.9% to 19.5%) among cases and 11.7% (95% CI, 7.4% to 17.0%) among control subjects (OR, 1.3; 95% CI, 0.7% to 2.3%). The prevalence of individual thrombophilias among cases ranged from 0.9% (95% CI, 0.1% to 3.4%) for protein S deficiency to 5.2% (95% CI, 0.3% to 9.1%) for antithrombin III deficiency; among control subjects, the prevalence ranged from 1.0% (95% CI, 0.1% to 3.6%) for protein S deficiency to 4.1% (95% CI, 0.2% to 7.8%) for antithrombin III deficiency. There were no significant differences in the prevalence of thrombophilia between cases and control subjects or between pathogenic subtypes of ischemic stroke. CONCLUSIONS: One in 7 patients with first-ever acute ischemic stroke will test positive for one of the inherited thrombophilias, but the relation is likely to be coincidental rather than causal in almost all cases, irrespective of the pathogenic subtype of the ischemic stroke. These results suggest that routine testing for thrombophilia in most patients with acute ischemic stroke may be unnecessary. Whether the thrombophilias may still be important in younger patients with ischemic stroke or in predicting complications (eg, venous thrombosis) and stroke outcome remains uncertain.  (+info)

Mesenteric venous thrombosis: a changing clinical entity. (7/74)

OBJECTIVE: Mesenteric venous thrombosis (MVT) and its clinical spectrum have become better defined following improvements in diagnostic imaging. Historically, MVT has been described as a morbid clinical entity, but this may not necessarily be true. Often, an underlying disease process that predisposes a patient to MVT can be found and potentially treated. This study was designed to evaluate the diagnostics and management of MVT and to review long-term results of treatment. PATIENTS: Thirty-one patients in whom MVT was diagnosed between 1985 and 1999 were retrospectively reviewed. Survivors were contacted for follow-up. There were 15 men and 16 women. Ages ranged from 22 to 80 years (mean, 49.1 years). Thirteen patients had documented hypercoagulability, 10 had a history of previous abdominal surgery, 6 had a prior thrombotic episode, and 4 had a history of cancer. MVT presented as abdominal pain (84%), diarrhea (42%), and nausea/vomiting (32%). Computed tomography (CT) was considered diagnostic in 18 (90%) of 20 patients who underwent the test. CT diagnosed MVT in 15 (100%) of 15 patients presenting with vague abdominal pain or diarrhea. Angiography demonstrated MVT in only five (55.5%) of nine patients. RESULTS: Seven of 31 patients died within 30 days (< 30-day mortality rate, 23%). Twenty-two patients (72%) were initially treated with heparin. Nine patients were not heparinized: four of them died, and two were later given warfarin sodium (Coumadin). Of the 31 patients, only one received lytic therapy. Three patients became symptom free without anticoagulation. Ten patients (32%) underwent bowel resection. Overall, 19 (79%) of 24 survivors were treated with long-term warfarin therapy. Long-term follow-up was obtained in 24 patients (mean, 57.7 months). Twenty-one (88%) of 24 survived in follow-up. CONCLUSION: The diagnosis of MVT should be suspected when acute abdominal symptoms develop in patients with prior thrombotic episodes or a documented coagulopathy. CT scanning appears to be the primary diagnostic test of choice. Anticoagulation is recommended. If diagnosed and treated early, MVT is not likely to progress to gangrenous bowel. Recent mortality rates for MVT are lower than previously published, perhaps because of earlier diagnosis and aggressive treatment or possibly because we now readily diagnose a more benign form of the disease, which is due to widespread use of CT scanning.  (+info)

Recombinant human transgenic antithrombin in cardiac surgery: a dose-finding study. (8/74)

BACKGROUND: Acquired antithrombin III (AT) deficiency may render heparin less effective during cardiac surgery and cardiopulmonary bypass (CPB). The authors examined the pharmacodynamics and optimal dose of recombinant human AT (rh-AT) needed to maintain normal AT activity during CPB, optimize the anticoagulant response to heparin, and attenuate excessive activation of the hemostatic system in patients undergoing coronary artery bypass grafting. METHODS: Thirty-six patients scheduled to undergo elective primary coronary artery bypass grafting and who had received heparin for 12 h or more before surgery were enrolled in the study. Ten cohorts of three patients each received rh-AT in doses of 10, 25, 50, 75, 100, 125, 175, or 200 U/kg, a cohort of six patients received 150 U/kg of rh-AT, and a control group of six patients received placebo. RESULTS: Antithrombin III activity exceeded 600 U/dl before CPB at the highest dose (200 U/kg). Doses of 75 U/kg rh-AT normalized AT activity to 100 U/dl during CPB. Activated clotting times during CPB were significantly (P < 0.0001) greater in patients who received rh-AT (844 +/- 191 s) compared with placebo patients (531 +/- 180 s). Significant (P = 0.001) inverse relations were observed between rh-AT dose and both fibrin monomer (r = -0.51) and D-dimer (r = -0.51) concentrations. No appreciable adverse events were observed with any rh-AT doses used in the study. CONCLUSIONS: Supplementation of native AT with transgenically produced protein (rh-AT) in cardiac surgical patients was well tolerated and resulted in higher activated clotting times during CPB and decreased levels of fibrin monomer and D-dimer.  (+info)

Looking for online definition of antithrombin III deficiency in the Medical Dictionary? antithrombin III deficiency explanation free. What is antithrombin III deficiency? Meaning of antithrombin III deficiency medical term. What does antithrombin III deficiency mean?
Antithrombin III deficiency (abbreviated ATIII deficiency) is a deficiency of antithrombin III. It is a rare hereditary disorder that generally comes to light when a patient suffers recurrent venous thrombosis and pulmonary embolism, and repetitive intrauterine fetal death (IUFD). Inheritance is usually autosomal dominant, though a few recessive cases have been noted. The disorder was first described by Egeberg in 1965. The patients are treated with anticoagulants or, more rarely, with antithrombin concentrate. In kidney failure, especially nephrotic syndrome, antithrombin is lost in the urine, leading to a higher activity of Factor II and Factor X and in increased tendency to thrombosis. Heparin enhances ATIII activity and neutralizes activated serine protease coagulation factors. Patients with ATIII deficiency requiring anticoagulant therapy with heparin will need higher doses of heparin. ATIII binds to thrombin and then forms the thrombin-anti thrombin complex or TAT complex. This is a ...

The Thrombosis VCEP plan to focus on curation of genes associated with Mendelian non-syndromic risk of venous thrombosis, such as protein S and C deficiencies, antithrombin deficiency (formerly antithrombin III deficiency), activated protein C resistance related to F5 and prothrombin. The VCEP will initially focus on SERPINC1 gene, associated with antithrombin deficiency, as this gene is one of the more sequenced genes for during a thrombophilia workup. We plan to move on to PROS1 and PROC to evaluate protein S and C deficiencies, respectively. As more pathogenic variants have been identified in the F5 and F2 genes related to thrombophilia risk, it will also be important to evaluate these genes for pathogenic variants in addition to the well described Factor V Leiden and Prothrombin variants.. The VCEP plans to meet monthly to begin specifying the ACMG/AMP Variant Curation Guidelines for SERPINC1. Once rule specifications are complete, we will then focus on PROS1 and PROC, which may only require ...

Test results may vary depending on your age, gender, health history, the method used for the test, and other things. Your test results may not mean you have a problem. Ask your healthcare provider what your test results mean for you. The results for both activity and antigen tests are given as percentages. Different labs use slightly different normal ranges, but in general, 80% to 120% is considered normal for adults. Newborns usually have about half as much antithrombin as adults. Thrombin levels in infants rise to adult levels by about 6 months of age.. People with genetically inherited antithrombin deficiency typically have test results between 40% and 60%.. In both type 1 and type 2 AT deficiency, the antithrombin activity test shows a low result because you dont have as much working antithrombin as you should have. When the AT activity test shows that levels are low, the antithrombin antigen test can then be used to find out whether the deficiency is type 1 or type 2.. If the follow-up ...

Antithrombin is a circulating plasma protein that functions as an important regulator of blood coagulation. It inactivates several enzymes of the coagulation cascade, in particular thrombin and factor Xa. Since a link between hereditary antithrombin deficiency and thrombosis was established in 1965, there has been increasing clinical interest in antithrombin and a need for simple and accurate determination. Assays based on chromogenic peptide substrates are now available, allowing photometric detection of antithrombin activity in plasma.. Thrombin is the key enzyme in blood coagulation. It clots blood by converting fibrinogen into clot-forming fibrin monomers and activates factor XIII leading to the strengthening of the blood clot by cross-linking. Thrombin also activates platelets and the cofactors, factor V and factor VIII, thereby accelerating its own generation and providing a quick response to injury. However, the autocatalytic nature of thrombin also entails certain hazards. The complete ...
Our two youngest boys have been diagnosed with Mitchondrial Disease. Our youngest had serum testing in 2009 which showed elevated lactate and pyruvate. This along with his other muscle problems and developing swallowing difficulty (aspirating liquids into his lungs and choking), led one of their doctors to order a muscle biopsy. The biopsy results took several months to complete. They showed a Complex I & III deficiency, a Complex III deficiency, an abnormal coupling ratio and sarcoplasmic masses. While the diagnosis was devestating, it did answer all of our extra questions and alowed us to start the proper supplements. There is no cure for Mitochondrial Disease. The only treatment is a high dose mixture of vitamins and supplements known to help mitochondrial function. Weve found an excellent place to order some of their supplements. Swanson Vitamins.

Mutations in the assembly chaperone BCS1L constitute a major cause of mitochondrial complex III deficiency. We studied the presence of BCS1L mutations in a complex III-deficient patient with metabolic acidosis, liver failure, and tubulopathy. A previously reported mutation, p.R56X, was identified in one BCS1L allele, and two novel heterozygous mutations, g.1181A|G and g.1164C|G, were detected in the second allele. The g.1181A|G mutation generated an alternative splicing site in the BCS1L transcript, causing a 19-nucleotides deletion in its 5UTR region. Decreased BCS1L mRNA and protein levels, and a respiratory chain complex III assembly impairment, determine a pathogenic role for the novel BCS1L mutations.

These studies provide convincing evidence that testing for the inherited thrombophilias should not be performed routinely in patients with ischemic stroke, even in the young. No case-control studies of PC, PS, or AT showed an association of these deficiencies and stoke. Multiple case-control studies have demonstrated no association between FVL or PTM and ischemic stroke in patients older than age 60. Case-control studies of FVL and PTM performed in unselected younger patients do not support an association of these disorders and stroke, and meta-analyses are unconvincing because of the inclusion of suboptimal data. Patients who do not have a white ancestor should not be tested for FVL or PTM, and the levels of PC and PS should be interpreted with caution because they may have ethnic variability that could lead to an erroneous diagnosis in patients of African descent. It is unclear if PFO in association with an inherited thrombophilia in the absence of an identified deep venous thrombosis should ...
How can this seemingly disparate evidence be integrated with what was known before? Older data, upon which the guidelines were based, had established that thrombophilia testing was predictive of the relative risk for initial VTE. The situation is completely different for patients who have already had a spontaneous VTE. Why? It has long been known that patients with spontaneous VTE are hypercoagulable, (untreated recurrence rates of 2% to 5% per year) no matter the result of thrombophilia testing. In part this is because comprehensive laboratory testing of clinically thrombophilic patients will yield negative results---no laboratory lesion--- in about 30%-40% of cases. The thinking is that those patients have a thrombophilic state that hasnt been discovered yet. To keep it in perspective, remember that the concept of hereditary thrombophilia has been around since the discovery, in 1963, of antithrombin deficiency (Egeberg O: Inherited antithrombin deficiency causing thrombophilia.

Test results may vary depending on your age, gender, health history, the method used for the test, and other things. Your test results may not mean you have a problem. Ask your healthcare provider what your test results mean for you. The results for both activity and antigen tests are given as percentages. Different labs use slightly different normal ranges, but in general, 80% to 120% is considered normal for adults. Newborns usually have about half as much antithrombin as adults. Thrombin levels in infants rise to adult levels by about 6 months of age. People with genetically inherited antithrombin deficiency typically have test results between 40% and 60%. In both type 1 and type 2 AT deficiency, the antithrombin activity test shows a low result because you dont have as much working antithrombin as you should have. When the AT activity test shows that levels are low, the antithrombin antigen test can then be used to find out whether the deficiency is type 1 or type 2. If the follow-up ...

This study will be a prospective, unblinded, non-randomized, open-label, multi-center Phase II/III study with 2 segments, i.e. a PK evaluation (Segment I), and an assessment of prophylaxis in surgical interventions and pregnancy/delivery, (Segment II). During the PK segment, the subjects would remain on their current anticoagulation therapy except for subjects on heparin therapy where a wash-out period of at least 5 half lives would be required. In total, 15 subjects with congenital ATIII Deficiency will be enrolled for the PK assessment (Segment I).. For Segment II, fifteen episodes will be treated. Recruitment of individual subjects with high risk for venous thrombosis for Segment II of this study is necessary because of the rarity of Antithrombin deficiency in the population. ...

Abstract: 53 patients with lung tuberculosis were divided in 3 groups in accordance with severety of disease. Leukocyte elastase, cationic proteins in neutrophils, activities of a 1-proteinase and a 2-macroglobulin were determined in patients plasma. Thromboelastographic, coagulating, fibrinolytic indices, and antithrombin III activity were also determined in 28 patients of all 3 groups. Results demonstrated the high level of leukocyte elastase (6-fold more than normal) in plasma of patients with acute tuberculosis process. This group of patients demonstrated activation of intravascular coagulation proceeded on the background of significant decrease (up to 60%) of AT III activity. Conclusion: Acuity and severety of tuberculosis process in lung may be characterized by high activity of leukocyte elastase. Degranulating activity of neutrophils and releasing of elastase are the reason of AT III deficiency and increasing of intravascular coagulating activity in tuberculosis ...

Inherited thrombophilia is a genetically determined tendency to thrombosis.1 In 1965 the first family with antithrombin deficiency was described, and for many years this was the only identifiable cause of thrombophilia.2 More recently, pedigree and case-control studies have confirmed that the risk of venous thrombosis is increased by deficiencies of antithrombin, protein C, and protein S, and by resistance to activated protein C.3-5 Other candidate genetic factors are included in table 1.J Clin Pathol 2000;53:167-170. The value of obtaining laboratory evidence of thrombophilia is the ability to predict the likelihood of recurrence in symptomatic patients and the risk of thrombosis in their relatives. Thus thrombophilia testing would be used to optimise the benefit/risk ratio of anticoagulant treatment. Therapeutic recommendations would have to be based on a risk-benefit analysis that considers the risk of the disease, the effectiveness of treatment, the risk of treatment, and the predictive ...
This study is the first to evaluate the long-term prognostic significance of hemostatic factor measurements in patients with angina pectoris and known coronary angiographic status. The clinical follow-up spanned 9.5 years, and complete follow-up information was available for 93% of the 225 patients initially recruited to the study. Although the number of patients investigated was comparatively small, the 58 patients with cardiac events, who represented more than a quarter of the original patient sample, allowed meaningful conclusions on risk relationships with hemostatic and angiographic baseline variables. Some earlier cross-sectional studies have indicated lower antithrombin III antigen or activity in patients with CAD compared with individuals without,32 33 34 35 while others have reported higher rather than lower values.36 37 In contrast, more recent investigations in large populations or patient cohorts failed to demonstrate an association of antithrombin III with the prevalence or extent ...

SUMMARY Thrombophilia refers to laboratory abnormalities that increase the risk of venous thromboembolism (VTE). Over the last several decades numerous factors have been identified. The most prevalent examples of hereditary forms of thrombophilia include the factor V Leiden and prothrombin G20210A mutations; deficiencies of the natural anticoagulants antithrombin, protein C, and protein S; persistently elevated levels of coagulation factor VIII; and mild hyperhomocysteinemia. Taken together, some form of hereditary thrombophilia can be identified in more than 50 percent of patients with VTE who are without obvious reasons for VTE, such as trauma or prolonged stasis. Moreover, hereditary thrombophilia has been associated with arterial cardiovascular disease and obstetric complications such as (recurrent) pregnancy loss and preeclampsia. The high yield of thrombophilia testing has led to widespread testing for these abnormalities in patients. Nevertheless, thrombophilia testing remains a topic of ...
List of 6 disease causes of Mesenteric venous thrombosis, patient stories, diagnostic guides. Diagnostic checklist, medical tests, doctor questions, and related signs or symptoms for Mesenteric venous thrombosis.
Thrombophilia (sometimes hypercoagulability or a prothrombotic state) is an abnormality of blood coagulation that increases the risk of thrombosis (blood clots in blood vessels). Such abnormalities can be identified in 50% of people who have an episode of thrombosis (such as deep vein thrombosis in the leg) that was not provoked by other causes. A significant proportion of the population has a detectable abnormality, but most of these only develop thrombosis in the presence of an additional risk factor. There is no specific treatment for most thrombophilias, but recurrent episodes of thrombosis may be an indication for long-term preventative anticoagulation. The first major form of thrombophilia, antithrombin deficiency, was identified in 1965, while the most common abnormalities (including factor V Leiden) were described in the 1990s. The most common conditions associated with thrombophilia are deep vein thrombosis (DVT) and pulmonary embolism (PE), which are referred to collectively as venous ...

Background: Antithrombin III is known as the most important natural inhibitor of thrombin activity and has been shown to attenuate local harmful effects of ischemia-reperfusion injury in many organs. In recent animal studies, delaying effect of remote organ ischemia-reperfusion injury on healing of intestinal anastomoses has been demonstrated. In this study, we investigated whether antithrombin III reduces deleterious systemic effects of ischemia-reperfusion injury on healing of colonic anastomoses in rats. ...

Antithrombin III (AT III) supplementation has proven to be effective in the treatment of disseminated intravascular coagulation. According to the study by the Kumamoto University School of Medicine , administration of AT III is also useful for prevention of organ failure in animals challenged with endotoxin or bacteria and it increases the survival rate of such animals. Since inhibition of coagulation abnormalities failed to prevent organ failure in animals given bacteria, AT III may exert a therapeutic effect independent of its anticoagulant effect. This therapeutic mechanism of AT III has been explored using an animal model of septicemia. AT III prevented pulmonary vascular injury by inhibiting leukocyte activation in rats given endotoxin. This effect is mediated by the promotion of endothelial release of prostacyclin which inhibits leukocyte activation. Interaction of AT III with heparin-like glycosaminoglycans (GAGs) on the endothelial cell surface appears to be important for this effect. ...

Compound:. Unfractionated heparin (UFH). Indications:. Heparin is preferred over warfarin in cases where it is necessary that the anticoagulant effect begins immediately. Its used to prevent deep vein thrombosis, pulmonary embolism and acute coronary syndromes.. Mechanism of action:. Antithrombin III is an endogenous molecule that inhibits factors II, IX, X, XI and XII and therefore the formation of fibrin. Heparin is a drug that increases the effect of antithrombin III and therefore has strong anticoagulant activity.. Heparin isnt actually a single molecule but a family of large and sulphated glycosaminoglycans that all act on antithrombin III. Heparin is actually present endogenously in the body inside the granules of mast cells. To acquire heparin the pharmaceutical industry extracts them from beef lung or pig intestine. However, because heparin isnt a single molecule can the biological activity of it differ depending on where it is extracted from. Because of this the dose of heparin is ...
