A 70-year-old man who visited Samsung Medical Center reported experiencing palpitation for 2 weeks. He had undergone excision of a mass in the right buttock due to rhabdomyosarcoma 7 years prior to this visit. Transesophageal echocardiography showed a pedunculated mass in the left ventricle, which was thought to be a vegetation of infective endocarditis, metastasis of the primary tumor, or thrombus. He underwent removal of the cardiac tumor, and the pathologic report was metastatic rhabdomyosarcoma. Thus, here, we report a rare case of metastatic rhabdomyosarcoma in the left ventricle.

Lemierre syndrome is caused by an infection in the oropharyngeal region with subsequent thrombophlebitis in the internal jugular vein. The thrombus from the thrombophlebitis can invade other vital organs, such as liver, lungs, or joints, resulting in secondary infection, which further exacerbates the fatal prognosis of this syndrome. Lemierre syndrome, also called postanginal sepsis or necrobacillosis, was first reported by Dr. Lemierre in 1936. In his report, Lemierre mentioned that out of 20 patients who suffered from this syndrome, only two survived. He also stated that all of the 20 patients complained of infections in the palatine tonsils and developed sepsis and thrombophlebitis in the internal jugular vein. Once called a "forgotten disease," this syndrome showed a very high mortality rate until usage of antibiotics became prevalent. In this case report, the authors present a 71-year-old female patient who suffered from Lemierre syndrome with thrombosis extended to the right sigmoid sinus.

Elsholtzia splendens, which grows on moist soil of mountainous regions, is widely distributed at all regions of Korea, especially at Mountain Ji ri. It is categorized as a Labiatae plant which is dried aerial part. It has the following medicinal properties; removal of fever, alleviation of pain, a good antiphlogistic agent as well as antibacterial effects. However, the effects of E. splendens on thrombosis and platelet activation are not precisely understood. We performed this study to develop antithrombotic agents from oriental medicine herb extracts. E. splendens inhibited platelet aggregation induced by arachidonic acid and U46619 in a concentration dependent manner. E. splendens did not show an effect on anticoagulation as determined by prothrombin time (PT) or activated partial thromboplastin time (aPTT). We also tested the effects of E. splendens using a carotid artery thrombosis rat model induced by 35% $FeCl_3$ treatment. E. splendens significantly inhibited thrombus weight compared with the control group. These results show that E. splendens may be developed as a potential antiplatelet activity agent for treatment of cardiocerebrovascular disease and atherosclerosis.

사구체에 면역글로불린은 음성이면서 C3 만 침착되는 경우, 다른 원인이 없는 경우 C3GN을 의심하여야 한다. 광학현미경으로는 세포의 증식이 있는 경우와 없는 경우가 있지만, 전자현미경으로는 EDD가 내피세포 밑으로 혹은 메산지움 등에 침착함을 확인하여야 한다. 대체보체경로의 조절이상이 원인임으로 혈청 C3 치를 비롯하여 CFH, CFI, CFB 등을 측정하여야 하며, C3 nephritic factor, antifactor H 자가항체 등을 조사하는 것이 필요하다. 보체 조절이상을 일으키는 유전자 돌연변이를 조사해 보아야 한다. 예후는 안정적이지만, 치료는 대증적이다. 이론적으로 보체의 활성화를 저지하는 약으로 가능할 것으로 생각되며, C5 항체인 eculizumab으로 치유된 보고도 있다.

We previously reported that in vitro anti-platelet activity of tissue-cultured mountain ginseng (TCMG) ethanol extracts show improved efficacy when compared with commercial ginseng products such as Korean red ginseng and Panax ginseng. However, information on the anti-platelet activity of the ethyl acetate fraction from TCMG adventitious roots is limited. Therefore, in this study, we further investigated the effects of an ethyl acetate extract of TCMG (EA-TCMG) adventitious roots on in vitro antiplatelet activity in whole human blood and its effect on peripheral blood flow in mice. We found that EA-TCMG inhibited platelet aggregation with $IC_{50}$ values of 271, 180, and 147 ${\mu}g$/mL induced by collagen, adenosine-5'-diphosphate, and arachidonic acid, respectively. Among the three agonists used, thromboxane $A_2$ formation induced by arachidonic acid was markedly suppressed. Furthermore, EA-TCMG improved the peripheral circulatory disturbance by improving vascular blood flow. In conclusion, these results suggest that ethyl acetate extracts from TCMG adventitious roots might inhibit vascular platelet aggregation and thrombus formation.

We investigated the antithrombotic effect of Acorus gramineus Soland (A. gramineus) from Korea and Acorus tatarinowii Schott (A. tatarinowii) from China in a rat model of arterial thrombosis induced by ferric chloride ($FeCl_3$). Thirty minutes prior to a 35% $FeCl_3$ application, Sprague Dawley rats were intraperitoneally injected with saline, A. gramineus and A. tatarinowii (100 mg/kg), respectively. Occlusion time of rats injected with A. gramineus was delayed significantly compared to that of the vehicle and A. tatarinowii. Thrombus weight was meaningfully decreased in rats injected with A. gramineus compared to the vehicle. Additionally, A. gramineus inhibited collagen fiber damage in vessel compared to the vehicle, but A. tatarinowii did not show a significant effect. Our results show that A. gramineus and A. tatarinowii from the same genus have different antithrombotic effects, and especially A. gramineus has a better antithrombotic effect than A. tatarinowii.

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.

The full-length cDNA of the lumbrokinase fraction 6 (F6) protease gene of Lumbricus rubellus was amplified using an mRNA template, sequenced and expressed in E. coli cells. The F6 protease gene consisted of pro- and mature sequences by gene sequence analysis, and the protease was translated and modified into active mature polypeptide by N-terminal amino acid sequence analysis of the F6 protease. The pro-region of F6 protease consisted of the 44 residues from methionine-1 to lysine-44, and the mature polypeptide sequence (239 amino acid residues and one stop codon; 720 bp) started from isoleucine-45 and continued to the terminal residue. F6 protease gene clones having pro-mature sequence and mature sequence produced inclusion bodies in E. coli cells. When inclusion bodies were orally administrated rats, generated thrombus weight in the rat' venous was reduced by approximately 60% versus controls. When the inclusion bodies were solubilized in pepsin and/or trypsin solutions, the solubilized enzymes showed hemolytic activity in vitro. It was concluded the F6 protease has hemolytic activity, and that it is composed of pro- and mature regions.
