Healing of the intimal dissection of the internal thoracic artery graft

We report healing of the intimal dissection of an internal thoracic artery graft. Triple coronary artery bypass grafting was performed using left internal thoracic artery and saphenous vein grafts. One month after operation, the intimal dissection of the internal thoracic artery graft was clearly visible by coronary angiography; however, after 1 year of only medical treatment consisting of warfarin, ticlopidine, and nitrate, the intimal dissection was undetectable by coronary angiography.

Iodine-impregnated drapes enable recording of precordial electrocardiogram

Although we believed that the use of a polyester film drape for primary elective open sternum with delayed sternal closure made it impossible to record precordial electrocardiograms on the drape, we confirmed that it is possible to record electrocardiograms on an iodine-impregnated drape due to the iodine anion electrical conductibility.

Clinical significance of sialic acid in patients with lung cancer.

原発性肺癌患者の血清, 組織中および血球細胞上のシアル酸を, チオバビルツール酸法によって検討した.血清中のシアル酸量は健常者に比し, 患者に有意に増加していた (P<0.01).組織型では, 腺癌および扁平上皮癌で有意な高値を示した (P<0.01).また扁平上皮癌では臨床病期の進行とともに増加した.肺癌組織で高値を示すことから, 増加したシアル酸は, 癌細胞に由来するであろうと考えられた.以上の結果から, 血清中のシアル酸の測定は, 肺癌患者の腫瘍マーカーとして有用であろうと思われた.
