Although thrombotic thrombocytopenic purpura (TTP) is a rare disease, when it develops in a post-cardiac surgery patient, it may have a fatal outcome. Since the frequency of early-onset thrombocytopenia in post-cardiac surgery patients is high, platelet concentrates are commonly transfused during postoperative management. However, when TTP is the likely diagnosis, platelet transfusion is not recommended. We experienced a postoperative TTP in a cardiac surgery patient and discovered the importance of identifying the etiology of postoperative thrombocytopenia. Here, we report the case with a brief review of the literature.

Purpose: Previously, Kawasaki disease (KD) treatment with low-dose aspirin was administered for 6-8 weeks after the acute phase. However, inflammatory marker levels normalize before 6-8 weeks. In this study, we aimed to investigate the clinical outcome of short-term low-dose aspirin treatment based on inflammatory and thrombotic marker levels. Methods: We performed a retrospective review of the medical records of patients with KD who were hospitalized at Chungnam National University Hospital between September 2012 and May 2014. When fever subsided, low-dose aspirin treatment was started. Inflammatory (white blood cell count, erythrocyte sedimentation rate, and C-reactive protein) and thrombotic markers (D-dimer) were monitored at follow-ups conducted in 1- to 2-week intervals. The low-dose aspirin administration was terminated when both markers were normalized and no cardiovascular complications were observed. Results: Eighty-four patients with KD (complete KD, n=49; incomplete KD, n=35) were enrolled. The inflammatory and thrombotic marker levels were normalized within 3-4 weeks on average. At the beginning the low-dose aspirin treatment, 9 patients had coronary artery lesions but 75 did not. When the low-dose aspirin administration was terminated at the time the inflammatory marker levels were normalized, no new CALs developed during the follow-up at 6-8 weeks. Conclusion: Most of the inflammatory marker levels were normalized within 3-4 weeks after the acute phase of KD. New cardiovascular complications did not develop during the course of the short-term aspirin treatment based on the inflammatory marker levels, clinical findings, and echocardiography.

Background: Behçet disease is a chronic inflammatory disorder with a varying etiology. Herein, we report the involvement of peripheral veins in Behçet disease and discuss the treatment thereof. Methods: Thirty-four patients with venous involvement in vasculo-Behçet disease were retrospectively analyzed over 15 years. We reviewed the clinical manifestations, treatment choices, and complications of these patients. Results: Deep vein thrombosis (DVT) was observed in 24 patients (70.59%) and varicose veins in 19 (52.94%). Immunosuppressive treatment was administered to all patients due to the pathological feature of vein wall inflammation. In patients with DVT, anticoagulation therapy was also used, but post-thrombotic syndrome was observed in all patients along with chronic luminal changes. Eleven patients with isolated varicose veins underwent surgery; although symptoms and lesions recurred in half of these patients, no cases of secondary DVT occurred. Conclusion: When DVT was diagnosed in patients with Behçet disease, there was no cure for the lesions. Ultrasonographic abnormalities were observed in all patients, and post-thrombotic syndrome remained to varying degrees. In cases of isolated varicose veins in patients with Behçet disease, DVT did not occur after surgical treatment. If the activity of Behçet disease is controlled, surgical correction of varicose veins is preferable.

In in vitro study, the anti-platelet aggregation effect of Shiitake mushroom extract was examined by measuring the collagen induced platelet aggregation and the DPPH radical scavenging. In in vitro study, anti-thrombotic effect of Shiitake mushroom extract was examined using the carotid artery thrombosis rat model. Carotid artery thrombosis rat model was made by 35% $FeCl_3$ treatment. After that, we investigate thrombus weight and blood flow. In platelet aggregation test, the extract significantly inhibited platelet aggregation in a concentration dependent manner(p<.001). Also, extract increased DPPH radical scavenging activity in a concentration dependent manner. Extract significantly inhibited thrombus weight to compare with control group. And blood passage time were shorter in the Shiitake mushroom extract supplemented groups than in control group. These results provide experimental evidence that Shiitake mushroom can be used to prevent platelet aggregation and thrombosis, then could apply the clinical diseases such as cardiovascular disease, and so on.

Inflammatory bowel disease (IBD) is a well-recognized risk factor for thrombotic events in adults but data on children are scarce. In the great majority of adult patients, thrombotic events are usually deep vein thrombosis and pulmonary embolism. Other sites such as jugular veins are extremely rare. We present a case of Lemierre syndrome in an adolescent girl with active ulcerative colitis and discuss possible risk factors. This is the first reported case of severe Lemierre syndrome with thrombus extension to cranial veins in a patient with ulcerative colitis. Early recognition of Lemierre syndrome in patients who present with rapidly worsening symptoms of neck pain, fever and signs of pharyngitis is imperative because it increases a chance of favorable prognosis. It is important for pediatricians treating IBD patients not to underestimate possible thrombotic events in children with IBD. Recognition of additional risk factors is crucial for prompt diagnosis and adequate treatment.

This study was performed to evaluate anti-thrombotic activities and anti-inflammatory effects of ChungyeolHaedogHwaeoTang water extract(CHHT). The results were summarized as follows. In experiment of anti-thrombotic effect; 1. CHHT inhibited human platelet aggregation induced by ADP and epinephrine as compared with the control group, and inhibited pulmonary embolism induced by collagen and epinephrine (inhibitory rate is 37.5%). 2. CHHT increased platelet number significantly, and also CHHT shortened PT and APTT significantly as compared with the control group in thrombus model induced by dextran. In experiment of anti-inflammatory effect; 3. CHHT inhibited $IL-1{\beta}$, IL-6, TNF-${\alpha}$, COX-2 and NOS-II mRNA expression as compared with the control group in a concentration-dependent degree, and inhibited NO production significantly at 50, 100 ${\mu}g/ml$, and also inhibited ROS production in a concentration-dependent degree as compared with the control of group in RAW 264.7 cell line. 4. CHHT inhibited $IL-1{\beta}$, IL-6 and TNF-${\alpha}$ production significantly in serum of acute inflammation-induced mice, and decreased $IL-1{\beta}$, IL-6 and TNF-${\alpha}$ production in spleen tissue, and also decreased $IL-1{\beta}$, and IL-6 production in liver tissue, but increased TNF-${\alpha}$ production in liver tissue of acute inflammation-induced Balb/c mice. 5. CHHT increased survival rate from the 3rd day in ICR mice with lethal endotoxemia induced by LPS. These results suggest that CHHT can be useful in treating diverse female diseases caused by thrombosis and inflammation such as menstrual pain, menstrual disorder, leukorrhea, vaginitis, cervicitis, pelvic inflammatory disease and so on.

Purpose: This study was performed to evaluate anti-thrombotic and anti-inflammatory effects of NeungaSoJeokTang water extract (NSJT). Methods: In the study of anti-inflammatory effects, NSJT was investigated using cultured cells and murine models. As for the parameters of inflammation, levels of several inflammatory cytokines and chemical mediators which are known to be related to inflammation were determined in mouse lung fibroblast cells(mLFC) and RAW 264.7 cells. Results: Prior to the experiment, we evaluated sGOT, sGPT, BUN and creatine after the treatment. As a result, NSJT was innoxious on liver and kidney. In experiment of anti-thrombotic effect, NSJT inhibited the platelet aggregation induced by ADP and epinephrine, and inhibited pulmonary embolism induced by collagen and epinephrine. NSJT did not affect significantly the blood flow rate both in vitro and in vivo. NSJT increased platelet number and fibrinogen amount, and NSJT shortened PT and APTT in thrombus model induced by dextran. In experiment of anti-inflammatory effect, NSJT inhibited $IL-1{\beta}$, IL-6, $TNF-{\alpha}$, COX-2 and NOS-II mRNA expression in a concentration-dependent manner in RAW 264.7 cell line, and inhibited significantly NO production at 50, 100 ${\mu}g/ml$, and also inhibited ROS production in a concentration-dependent manner. NSJT inhibited $IL-1{\beta}$, IL-6 and $TNF-{\alpha}$ production significantly in serum of acute inflammation-induced Balb/c mice, and decreased $IL-1{\beta}$, IL-6 and $TNF-{\alpha}$ production in spleen tissue, but increased $IL-1{\beta}$, IL-6 and $TNF-{\alpha}$ production in liver tissue. NSJT increased survival rate at the 3th day in ICR mice with lethal endotoxemia induced by LPS. Conclusion: These results suggest that NSJT can be used for treating diverse female diseases caused by thrombosis and inflammation such as pelvic pain, pelvic inflammatory disease as well as vulvar pain due to vulvitis, vulvar vestibulitis and so on.

Euchrestaflavanone A (EFA) is a flavonoid found in the root bark of Cudrania tricuspidata. C. tricuspidata extract, widely used throughout Asia in traditional medicine, has been investigated phytochemically and biologically and is known to have anti-obesity, anti-inflammatory, and anti-tumor effects. It has been reported that C. tricuspidata extract also possesses anti-platelet effects; however, the mechanism of its anti-platelet and anti-thrombotic activities is yet to be elucidated. In this study, we investigated the effects of EFA on the modulation of platelet function using collagen-induced human platelets. Our results showed that EFA markedly inhibited platelet aggregation. Furthermore, it downregulated glycoprotein IIb/IIIa (αIIb/β3)-mediated signaling events, including platelet adhesion, granule secretion, thromboxane A2 production, and clot retraction, but upregulated the cyclic adenosine monophosphate-dependent pathway. Taken together, EFA possesses strong anti-platelet and anti-thrombotic properties and is a potential therapeutic drug candidate to prevent platelet-related thrombosis and cardiovascular disease.
