The Cox-Maze procedure was designed to address the consequences of atrial fibrillation, tachycardia, hemodynamic impairment, and thromboembolism. From 1991 until June 1999, 100 patients underwent the Maze operation at the Cleveland Clinic Foundation. The group included 72 men with a mean age of 58 +/- 11 years (range, 23 to 78 years). Initially, the Maze-I(More)
BACKGROUND Left ventricular contractility in atrial fibrillation is known to change in a beat to beat fashion, but there is no gold standard for contractility indices in atrial fibrillation, especially those measured non-invasively. OBJECTIVE To determine whether the non-invasive index of contractility "preload-adjusted PWR(max)" (maximal ventricular(More)
We developed a simple, kinetic method for the determination of catalase activity in which i) the enzyme catalyzes the peroxidation of ethanol by hydrogen peroxide to acetaldehyde and water, and ii) the acetaldehyde so formed is rapidly oxidized to acetic acid and NADPH by the addition of an excess of NADP+ and aldehyde dehydrogenase. The rate of NADPH(More)
BACKGROUND AND PURPOSE Earlier we reported that 7,8-dihydro-8-oxo-deoxyguanosine (8-oxo-dG), an oxidatively modified guanine nucleoside, exerted anti-inflammatory activity through inactivation of the GTP binding protein, Rac. In the present study, the effects of 8-oxo-dG were investigated on responses to antigen challenge in sensitized mice, as Rac is also(More)
It has been reported that Vacor, a rodenticide containing N-3-pyridylmethyl-N'-p-nitrophenyl urea, causes insulin-dependent diabetes mellitus. The pathomechanism of Vacor-induced diabetes mellitus has not been clarified yet. The effect of Vacor, therefore, was studied in terms of insulin release from isolated rat pancreatic islets. Vacor suppressed(More)
PURPOSE This study investigated the effect of accumulated dose on radiophotoluminescent glass dosimeter in megavoltage photon. METHODS 45 commercially-available radio-photoluminescence glass dosimeters (RPLGD; GD-302M, Asahi Techno Glass Co., Shizuoka, JAPAN) were irradiated to 10 × 10 cm2 open-field with 6, 10 and 15 MV photon beams at 100 cm of source(More)
PURPOSE Confirming the dose delivered to a patient is important to make sure the treatment quality and safety of the radiotherapy. Measuring a transit dose of the patient during the radiotherapy could be an interesting way to confirm the patient dose. In this study, we evaluated the feasibility of the transit dosimetry with a glass dosimeter in(More)
PURPOSE To evaluate the reliability of RPN (Risk Priority Number) decided by expert group and to provide preliminary data for adapting FMEA in Korea. METHODS 1163 Incidents reported in ROSIS for 11 years were used as a real data to be compared with, and were categorized into 146 items. The questionnaire was composed of the 146 items and respondents had to(More)
Changes in the levels of biogenic amines in different brain regions and the cerebrospinal fluid in rats were measured after acute or chronic treatment with tricyclic antidepressants. After single or 3 weeks' treatment with imipramine or desipramine, blocks of tissues were obtained from seven regions of the brain (frontal cortex, corpus striatum,(More)
