Ru(II)-terpyridine complexes (8, 9, 11) linked with adamantyl or β-cyclodextrin moieties were synthesized and characterized based on their 1H and 13C NMR spectra as well as MS spectra. Ru(II)-terpyridine complexes (8, 11) linked with adamantyl moiety were readily dissolved in aqueous solution via encapsulation by β-cyclodextrin when they were mixed with an equimolar amount of β-cyclodextrin. In the similar way, the adamantane guest of the Ru(II)-terpyridine complexes (8, 11) were encapsulated by β-cyclodextrin moiety of the ruthenium complex 9 to afford supramolecular assemblies in aqueous environment. Formation of assemblies was corroborated by 1H NMR spectroscopy. 아다만탄 또는 β-cyclodextrin이 결합된 루테늄(II)-터피리딘 착화합물(8, 9, 11)을 합성하고 1H NMR, 13C NMR 및 질량분석스펙트럼으로 구조를 확인하였다. 아다만탄이 결합된 루테늄(II)-터피리딘 착화합물(8, 11) 은 물에 전혀 녹지 않으나, β-cyclodextrin 수용액에 혼합할 경우 β-cyclodextrin과의 초분자를 형성하여 물에 잘 녹아들어갔다. 비슷한 방법으로 수용액 중에서 루테늄(II)-터피리딘 착화합물(8, 11)을 각각 착화합물 9와 혼합 하였을 때, 착화합물(8, 11)의 아다만탄 부분이 루테늄 착화합물 9의 β-cyclodextrin 내부에 포접 됨으로써 안정 한 초분자를 형성하였다.

Ischemic colitis is one of the most common intestinal ischemic injury in which more than 90% of patient are over 60 year-old. It results from impaired perfusion of blood to the bowel and is rarely caused by vasculitis such as systemic lupus erythematosus, polyarteritis nodosa, and Takayasu`s arteritis. Takayasu`s arteritis affects the aortic arch, medium-sized and large arteries but rarely involves inferior mesenteric artery. We report a case of Takayasu`s arteritis involving inferior mesenteric artery which developed ischemic colitis in a 70 year old female. To the author`s knowledge this is the first case report in Korea. A 70 year old woman who had suffered from Takayasu`s arteritis for 5 years was admitted for sudden abominal pain and hematochezia. On sigmoidoscopy, there were multiple segmental longitudinal ulcerations around splenic flexure and diffuse hemorrhagic edematous mucosa from descending colon to sigmoid colon. On abdominal CT angiography, inferior mesenteric artery was not traced. We diagnosed it as ischemic colitis combined with Takayasu`s arteritis. After the conservative treatment, abdominal pain and hematochezia disappeared. She was followed up to 2 years without recurrence of symptoms. (Korean J Gastroenterol 2007;49:110-113)
