Hill, MD, Syed Ali, MD, Michael Pasque, MD, Heidi Tymkaw, MHS, Mary Finayev, RRT, Barnes-Jewish Hospital and Washington University School of Medicine, St. Louis, MO Objective To determine if administration of supplemental carbon dioxide, results in improved cardiac index and peripheral tissue oxygenation in the post-operative cardiac surgery patient Design Prospective, randomized, cross-over design of post-operative patients in the cardiothoracic intensive care unit at Barnes-Jewish Hospital; Study groups were randomized into a differing sequence of arterial CO2 tensions: Group 1 304050 mmHg, Group 2- 405030 mmHG, and Group 3 503040 mmHg. The study goal is twenty-four patients following elective heart surgery; nine patients have been studied to date. Method Patients were sedated with propofol and fentanyl, and paralyzed with rocuronium. All patients had a pulmonary artery catheter and an arterial line interfaced with an indwelling blood gas analyzer. Prior to the study, a transcutaneous monitor was placed close to the sternum to monitor oxygen tension. A Novametrics NICO2 monitor was placed inline with the ventilator circuit, utilizing a Capnostat CO2 sensor. Once patients were stable in the ICU, mechanical ventilator settings were adjusted to attain an initial PaCO2 of 30. Patients were randomized into Group 1, 2, or 3. Supplemental CO2 was bled into the inspiratory limb of the ventilator circuit to attain the desired PaCO2 levels. Patients were placed in A C mode and tidal volume adjusted to compensate for additional CO2 flow and to maintain exhaled minute ventilation throughout the study. No other changes to the mechanical ventilator were made except in emergencies. No additional medical interventions i.e., no changes in medications, fluids ; were made. Upon achieving each desired PaCO2 level 3 mmHg ; , hemodynamic measurements, respiratory mechanics, and ABGs were recorded.

L-Asp ; is an effective drug for the treatment of children with acute lymphoblastic leukemia ALL ; .1, 2 In newly diagnosed patients with ALL, 25% to 60% will reach a complete remission after monotherapy with L-Asp.1 The efficacy of this drug is generally thought to result from a rapid and complete depletion of asparagine in plasma by hydrolyzing this amino acid to aspartic acid. L-Asp resistance has been attributed to high levels of intracellular asparagine synthetase AS ; .3 Cell line studies showed that L-Aspsensitive leukemic cells have low intracellular AS activity and are dependent on the availability of extracellular asparagine.4 Andrulis et al demonstrate that complete asparagine depletion in vitro results in an amino aciddependent up-regulation of mRNA, protein, and activity of AS.5 Resistance to L-Asp in cell lines is in vitromediated by an up-regulation of AS expression in response to asparagine depletion of culture medium.6, 7 Whereas these cell line studies suggest that up-regulation of AS expression is an important mechanism of L-Asp resistance, clinical evidence is lacking for this assumption. In recent studies we found evidence that a high baseline intracellular AS gene expression is related to in vitro L-Asp resistance in children with TEL AML1negative ALL, 8 but not in TEL AML1positive children.9 This suggests that the genotype plays an important role in the cause of L-Asp resistance. However, it is yet unknown whether baseline and or L-Aspinduced AS mRNA levels are linked to the clinical response to this drug given as a therapeutic window upfront of combination chemotherapy. In the present in vivo study we investigate whether baseline and or L-Aspinduced AS mRNA levels are related to the clinical.

Difference in the time taken to harvest the radial artery or the Doppler flow of the anastomosed vessels. He also performed electron microscopy of samples of the radial artery. The lowest level of damage was found in pedicled arteries using the harmonic scalpel, but skeletonizing with the harmonic was associated with a high level of damage. Mustafa Cikirikcioglu w7x took the discarded ends of 14 radial arteries that were harvested using either the scissors and clips technique or the harmonic scalpel method. They were then placed in an organ bath and subjected to a series of vasoconstrictors and vasodilators. There were no significant differences found. The samples were also examined by electron microscopy and no differences were found. Wright et al. w8x randomized 51 patients to harmonic scalpel or `cold-steel' scalpel techniques. There was no difference in the time taken to harvest the vessel, the quality of the graft or the need for repeat angiography at 3 months. Bhan et al. w9x used the harmonic scalpel to harvest all arterial conduits including the LIMA in 80 patients, and compared this to a retrospective cohort. They could not and sulfasalazine.

Materials and Methods Chemicals. 4-Hydroxy sulfadiazine, 5-hydroxy sulfadiazine, N-hydroxy sulfadiazine the hydroxylamine ; , and N-acetyl sulfadiazine were obtained from the National Institute of Allergy and Infectious Diseases AIDS Research and Reference Reagent Program Bethesda, MD ; . Sulfadiazine was purchased from Sigma-Aldrich St. Louis, MO ; . N-Acetyl sulfamethazine was a gift from Dr. Edith Sim, University of Oxford Oxford, UK ; , and N-acetyl p-aminobenzoic acid was obtained from Aldrich Chemical Milwaukee, WI ; . All other chemicals were of analytical grade and were obtained commercially. Human Liver Samples. Livers were procured, processed, and stored as previously described Rettie et al., 1989 ; . Microsomes HL123, -126, -135, -141, and -142 ; were prepared as previously described Hickman et al., 1998 ; . Cytosol was prepared by homogenizing human liver in a buffer containing 250 mM sucrose, 100 mM dihydrogen potassium phosphate, 1 mM EDTA, 1 g ml leupeptin, and 1 mM dithiothreitol at pH 7.4. The liver homogenate was centrifuged at 15, 000g at 4C for 20 min, and the supernatant was poured through two layers of gauze into fresh centrifuge tubes and then centrifuged at 100, 000g at 4C for 1 h to isolate the cytosol as the supernatant. The supernatant was aliquoted immediately and then frozen in liquid nitrogen before storing at 70C. Protein concentrations were determined by the Bradford assay with bovine serum albumin standard supplied by Bio-Rad Hercules, CA ; . Cloned Human Enzymes. Lymphoblast and baculovirus insect cell-expressed Supersome ; human cytochrome P450 enzymes were obtained from BD Gentest Woburn, MA ; . Bacterially expressed NAT1 * 3 and NAT2 * 4 both the human wild type ; were provided by Drs.
