 | Twelve dogs were divided into two groups of 6 and were infused with bis (3,4 dibromosalicyl) fumarate stroma free hemoglobin (DBBF-Hb) or albumin. Their responses to an intravenous bolus of E.coli were followed for four hours. Bacterial clearance from the bloodstream was studied using standard colony count methodology as well as blood counts, blood chemistries and clotting factor analysis. There was a significant difference in MAP ... |

|
 | Human CPD-collected red blood cells from 7 healthy male volunteers were stored in ADSOL (adenine, glucose, mannitol, and sodium chloride solution) at 4C for various periods: the red blood cells from one volunteer were stored for 35 days; red blood cells from 3 volunteers were stored for 42 days; and red blood cells from 3 other volunteers were stored for 49 days. A 100 ml aliquot ... |

| Effect of Surface Treatment on Fatigue Properties of Al-Li-Cu-Mg-Zr and Al-Zn-Mg-Cu-Zr Plate |

|
| The effects of surface treatments on the fatigue lifetime of 8090 (Al-Li-Cu-Mg-Zr) and 7010 (Al-Zn-Mg-Cu-Zr) alloys have been assessed, using a rotating bend fatigue testing machine at a stress ratio R = -1. It was found that the fatigue performance of alloy 8090 was less susceptible to chromic/ sulfuric pickling than alloy 7010 and shot peening was more beneficial for the lithium containing alloy. Excellent fatigue properties were also exhibited ... |

| The Influence of Microstructure on the Environmental Cracking Behaviour of Al-Li-Cu-Mg-Zr Alloys |

|
| This paper presents a study of the effects of heat treatment and zinc addition on the stress corrosion cracking (SCC) behavior of some Al-Li alloys. Results show that SCC resistance can be improved by complex heat treatments or by zinc addition to the alloy. Crack resistance is controlled by the type and distribution of precipitates within the matrix and on the grain boundaries. |

|
| The background to the Alcan development of two Al-Li-Cu-Mg alloys and the processing of rolled and extruded material under commercial conditions are outlined. Current typical properties of sheet, plate and extrusions in Lital A, (to replace 2014), Lital B (to replace 7075), and Lital C (to replace 2024) are shown together with their relationship to fabrication and heat treatment parameters. Details of the environmental behavior of the alloys are included. ... |

|
| Aluminum-lithium based alloys are not immune to stress corrosion cracking, but in terms of alternate immersion crack initiation testing they are less susceptible than extensively used aerospace alloys (e.g. 2014) which do not cause significant cracking problems in service. Survival criteria can readily be achieved particularly if copper concentrations are kept below 2.0% and overaging practices are employed. Strength penalties are insignificant due to the flat aging plateau. |

| A Comparison of Methods Used for Determination of the 100% Survival of Preserved Red Blood Cells |

|
| Three methods were evaluated to determine which gave the most accurate 100% survival value from which to estimate the 24-hour posttransfusion survival of 51Cr-labeled preserved red blood cells: (1) indirect measurement of the recipient's red blood cell volume using 125I albumin and the total body area nomogram; and (3) extrapolation of the radioactivity associated with the red blood cells in the recipient's circulation after the transfusion. When less than 20% ... |

| Freeze-Preservation of Horse Red Blood Cells Using 20% W/V Glycerol and Storage at -150 C for 5 Years |

|
| Horse red blood cells frozen with 20% W/V glycerol and stored at -150 C for as long as 5 years showed no adverse effects on freeze-thaw or freeze- thaw-wash recovery or red cell oxygen transport function related to the length of frozen storage. |

| Monkey Red Blood Cells Frozen with 40% (w/v) Glycerol and Storage at - 80C |

|
| Red blood cells of Rhesus monkeys cryopreserved with 40% (w/v) glycerol and storage at -80 C had freeze-thaw-wash recovery values of 87%, 24- hour posttransfusion survival values of 85%, and lifespan values of 13 days. Our data show that the monkey is an excellent model in which to study liquid and freezing methods of preserving RBC before conducting tests in humans. |
