Abstract
ZusammenfassungZum gegenwärtigen Zeitpunkt ist in der EU und den USA kein artifizieller Sauerstofftransporter zugelassen. Hämoglobin-basierte Sauerstoff-Carrier (HBOC) sind bereits seit Jahrzehnten Gegenstand wissenschaftlicher Untersuchungen. Ein wesentliches Hindernis bei der Zulassung war bisher der Anspruch der Entwickler, einen universell einsetzbaren Blutersatz zu produzieren. Die Beschränkung auf eine Indikation scheint erfolgversprechender zu sein. Der Ansatz, nicht nur Sauerstoff von der Lunge zum Gewebe, sondern auch der Abtransport von Kohlendioxid vom Gewebe zur Lunge zu transportieren, der effektiver als mit Erythrozyten durchgeführt werden kann, erscheint besonders attraktiv. Aufgrund vielversprechender präklinischer sowie klinischer Untersuchungen besteht die Hoffnung, dass in absehbarer Zeit auch in der EU künstliche Sauerstofftransporter für therapeutische Zwecke zur Verfügung stehen werden.

Abstract
Oxygen (O2) delivery to tissues plays an important role in determining microcirulatory autoregulatory responses. The balance between O2 delivery by whole blood and tissue O2 consumption likely has evolved based on regulatory processes designed to accommodate the encapsulation of hemoglobin (Hb) within red blood cells (RBCs). The hemodynamic, rheologic, and physical properties of blood, or an alternate O2-carrying solution, can have important consequences for O2 delivery to tissue. The development of acellular hemoglobin-based oxygen carriers (HBOC) requires reassessment of the O2 loading and unloading charactistics of Hb. the effects of altering the rheologic properties of blood, and the impact of these changes on microcirculatory autoregulation and tissue oxygenation. A variety of experimental and clinical studies have demonstrated beneficial effects of HBOCs. However, mechanisms responsible for HBOC-facilitated, O2-dependent autoregulatory changes in the microcirculation have not been completely elucidated.

Abstract
UNLABELLED Hemoglobin-based oxygen carrier-201 (HBOC-201, hemoglobin glutamer-250 [bovine], Hemopure; Biopure Corporation, Cambridge, MA) is polymerized hemoglobin of bovine origin being developed as an oxygen therapeutic. In this study, we evaluated the tolerability of a single intraoperative dose of HBOC-201 in surgical patients. In a single-blinded, multicenter study, 81 patients were randomized to receive either a single infusion of HBOC-201 (55 patients) or an equivalent volume of lactated Ringer's solution (26 patients). Forty-two patients originally assigned to the HBOC-201 group received the entire planned treatment of only one of the following doses: 0.6, 0.9, 1.2, 1.5, 2.0, or 2.5 g/kg of body weight. Thirteen of the 55 patients in the HBOC-201-assigned group did not reach the trigger point for transfusion administration, and they were not included in the analysis. We studied clinical outcomes and compared hematologic findings, blood chemistry values, and blood use in the two treatment groups. There were no patient deaths in this study. No pattern of clinically significant laboratory abnormalities could be attributed to exposure to HBOC-201. In the HBOC-201 group, 2 patients had a transient increased concentration of serum transaminases and 6 had transient skin discoloration. One patient in the HBOC-201 group had mast cell degranulation with hypotension. Postoperatively, methemoglobin plasma concentrations increased in the HBOC-201 group in a dose-dependent manner, reaching maximal values of 3.7% +/- 3.2% (average of all doses given) on postoperative day 3. There was no difference in the mean number of allogeneic blood units transfused in the 2 groups (3.3 +/- 1.8 and 3.7 +/- 4.1 for the lactated Ringer's solution and HBOC-201 groups, respectively) over the course of hospitalization. The intraoperative administration of HBOC-201, up to a maximum of 245 g, was generally well tolerated. There was no relationship between HBOC-201 use and the number of allogeneic blood units transfused over the entire hospitalization course. The administration of HBOC-201 was associated with a delayed (third postoperative day) dose-dependent increase in the plasma methemoglobin concentration. We conclude that the intraoperative use of HBOC-201 was generally well tolerated. IMPLICATIONS The intraoperative use of hemoglobin glutamer-250 (bovine) (HBOC-201, Hemopure was generally well tolerated. The administration of HBOC-201 was associated with a delayed increase in the plasma methemoglobin concentrations.

Abstract
The influence of somatic growth and genetic selection on the whole blood oxygen equilibrium curve (OEC) was measured under standard conditions in double-muscled and dairy calves during their first 3 mo of life. Crossbreed animals were also investigated. Hemoglobin, 2,3-diphosphoglycerate (DPG), Cl, and Pi concentrations were also measured. The percentage of fetal hemoglobin (HbF) was determined. The influence of exogenous Cl, Pi, and pH on the OEC was also assessed. The PO2 at 50% hemoglobin saturation (P50) increased during somatic growth, probably because of the increase in DPG recorded in double-muscled neonates and to the progressive disappearance of HbF in both breeds. The oxygen exchange fraction (OEF%) was used to assess the combined influence of the OEC shift and OEC shape changes on blood oxygen desaturation under standard conditions, when the PO2 decreases within a physiological range. The OEF% showed an increase during the first month, then a stabilization. The effects of Cl, Pi, and pH in Friesian calves were similar as in adult cattle. Double-muscled neonates had a lower P50, OEF% values, and DPG concentrations and higher hemoglobin and Cl concentrations than Friesian neonates. The Pi concentration and the percentage of HbF were similar in both breeds. The pH and the Cl concentration had significantly less effect on the OEC in double-muscled than in Friesian calves. Crossbreed animals exhibited intermediate parameter values, between those recorded for double-muscled and Friesian calves. All differences between breeds progressively disappeared during the first month. These data show that blood function changes markedly in calves during the first month of life and that genetic selection can alter blood function.

Abstract
PURPOSE This study compares the effects of stored red cells, freshly donated blood and ultrapurified polymerized bovine haemoglobin (HBOC) on haemodynamic variables, oxygen transport capacity and muscular tissue oxygenation after acute and almost complete isovolaemic haemodilution in a canine model. METHODS Following randomization to one of three groups, 24 anaesthetized Foxhounds underwent isovolaemic haemodilution with 6% hetastarch to haematocrit levels of 20%, 15% and 10% before they received isovolaemic stepwise augmentation of 1 g.dl-1 haemoglobin. In Group 1, animals were given autologous stored red cells which they had donated three weeks before. In Group 2, animals received freshly donated blood harvested during haemodilution. In Group 3, animals were infused with HBOC. Skeletal muscle tissue oxygen tension was measured with a polarographic 12 mu needle probe. RESULTS In all groups, heart rate and cardiac index were increased with decreasing vascular resistance during haemodilution (P < 0.05). Haemodynamic variables showed a reversed trend during transfusion when compared to haemodilution but remained below baseline (P < 0.05). Arterial and venous oxygen content were changed in parallel to changes of haematocrit and haemoglobin concentrations but were lower in Group 3 than in Groups 1 and 2 (P < 0.05) during transfusion. In contrast, the oxygen extraction ratio was higher in Group 3 (59 +/- 8%, P < 0.01) at the end of transfusion than in Group 1 (37 +/- 13%) and 2 (32 +/- 5%). In Group 3, mean tissue oxygen tension increased from 16 +/- 5 mmHg after haemodilution to 56 +/- 11 mmHg after transfusion (P < 0.01) and was higher than in Group 1 (41 +/- 9, P < 0.01) and Group 2 (29 +/- 11, P < 0.01). While in Group 3 an augmentation of 0.7 g.dl-1 haemoglobin resulted in restoring baseline tissue oxygenation, higher doses of 2.7 g.dl-1 and 2.1 g.dl-1 were needed in Groups 1 and 2 to reach this level (P < 0.01). CONCLUSION The results show a higher oxygenation potential of HBOC than with autologous stored red cells because of a more pronounced oxygen extraction.

Abstract
OBJECTIVE To evaluate the physiology and pharmacokinetics of a novel hemoglobin-based oxygen carrier of bovine origin. DESIGN Randomized, single-blind, placebo-controlled, dose-escalation study. SETTING The Upjohn Research Clinics (Kalamazoo, MI). SUBJECTS Normal healthy adult men between the ages of 18 and 45 yrs. There were 18 subjects who received active treatment and 23 controls. INTERVENTIONS All subjects had phlebotomy of 15% of blood volume (performed in <15 mins) followed by isovolemic hemodilution (3:1, Ringer's lactate to the volume of whole blood removed) over a 90-min period, and either active drug (polymerized bovine hemoglobin) or a control infusion of lactated Ringer's solution (each infusion given over a total of 4.3 hrs). The subjects randomized to active treatment received a loading dose and a continuous infusion of polymerized bovine hemoglobin for a total dose of 16.5, 24.1, 30.2, 38.0, or 45.0 g. All subjects had an indwelling radial artery catheter (for blood pressure and arterial blood gas measurements), determination of cardiac function (by impedance plethysmography), serial pulmonary function tests (spirometry and diffusion capacity), and metabolic cart measurements. MEASUREMENTS AND MAIN RESULTS Pharmacokinetics of the plasma bovine hemoglobin demonstrated that the elimination of the hemoglobin-based oxygen carrier was a linear, first-order process and that there was no renal excretion. Peak plasma concentrations were between 1 to 2 g/dL and plasma half-life approached 20 hrs at the highest doses given. Diffusion capacity of oxygen was increased up to 20% above baseline in the 38.0 and 45.0 g groups in comparison with controls (approximately 14% below baseline) between 2 and 24 hrs after the infusion (p < .01). Other pulmonary function tests and arterial blood gas measurements were unremarkable. Arterial oxygen content and oxygen delivery tended to be greater in active groups than in controls. CONCLUSIONS The plasma concentrations of bovine hemoglobin were directly proportional to the doses administered. An increase in diffusion capacity paralleled the plasma bovine hemoglobin concentrations. Dosing of the hemoglobin-based oxygen carrier of bovine origin to a target plasma hemoglobin concentration can be achieved using pharmacokinetic principles with measurable effects on oxygen physiology.

Abstract
STUDY OBJECTIVE Hemoglobin-based oxygen carrier 201 (HBOC-201) is a polymerized hemoglobin of bovine origin being developed for use in hemorrhage during surgery or trauma. Pulse oximetry is commonly used in clinical practice to assess percent saturation of hemoglobin (Spo2). The ability to measure Spo2 in the presence of HBOC-201 will be important for the use of this compound in patient care. METHODS We carried out a randomized, single-blind, placebo-controlled study at the Upjohn Research Clinics in Kalamazoo, Michigan, with normal, healthy adult men and women as subjects. The members of four groups of adult subjects (N=24) each received 45 g of HBOC-201 (nine each, men and women) or a control solution (Ringer's lactate) (three each, men and women). Each subject underwent phlebotomy (about 15% of estimated blood volume) followed by 3:1 hemodilution with Ringer's lactate and then either HBOC-201 or control solution. An indwelling arterial catheter in the radial artery was used for serial arterial blood gas sampling. Arterial blood gas measurements were made with a cooximeter (Instrumentation Laboratories). Fingertip pulse oximetry was used (Criticare 504-US; Criticare, Incorporated). Paired pulse oximetry and arterial blood gas sampling were made serially (at approximately hourly intervals) over 24 hours. RESULTS The mean +/- SEM difference for Spo2 for arterial blood gas analysis compared with the pulse oximetry reading in the presence of HBOC-201 was 1.1% +/- 0.75%; in controls it was .1% +/- 0.64% (P<.001) for each) over the 24 hours after dosing. This relationship was constant despite increased concentrations of plasma hemoglobin (between 1 and 2g/dl [10 to 20 g/L]) in the HBOC-201 groups. CONCLUSION Accurate determinations of Spo2 can be made with pulse oximetry in subjects given HBOC-201 over the normal range of Spo2.

Abstract
OBJECTIVE The objective of this study was to evaluate the exercise capacity of subjects given an autologous transfusion or a polymerized bovine hemoglobin solution to define the pharmacodynamics and pharmacokinetics of a new hemoglobin-based oxygen carrier (HBOC-201). METHODS Six normal healthy male subjects (ages 25 to 45 years) participated in this randomized, single-blind, two-way crossover study, which took place at Upjohn Research Clinics in Kalamazoo, Mich. A radial artery catheter was inserted in each subject before serial cardiac output and pulmonary function tests and phlebotomy of 15% blood volume (750 ml plus another 250 ml for study laboratories yields 1000 ml, or about 150 gm human hemoglobin). This was followed by isovolemic hemodilution with Ringer's lactate plus an autologous blood transfusion (or HBOC-201) and 1 week later 45 gm bovine hemoglobin of HBOC-201 (or autologous transfusion). Bicycle exercise stress tests to anaerobic threshold (approximately 65% of predicted maximum aerobic capacity) were done before phlebotomy and at approximately 45 minutes after the autologous transfusion or HBOC-201 infusion. RESULTS Subjects had similar exercise and diffusion capacity but lower lactate levels (for up to 24 hours) during HBOC-201 (which paralleled plasma HBOC-201 levels) than during autologous transfusion periods. Oxygen use (uptake) and carbon dioxide production at rest were greater during the HBOC-201 infusion than during the autologous transfusion period. The half-life of HBOC-201 was about 23 hours. CONCLUSIONS Exercise capacity and diffusion capacity were similar after HBOC-201 and autologous transfusion. HBOC-201 resulted in greater oxygen (or uptake) and carbon dioxide production and lower lactate levels compared with autologous transfusion. Under the conditions of the study, the physiologic effects of 1 gm bovine hemoglobin of HBOC-201 were similar to 3 gm human hemoglobin from autologous transfusion.

Abstract
Tumor oxygen tensions were measured using a computer-controlled PO2 microelectrode in two preclinical solid tumor models, the rat 9L gliosarcoma and the rat 13672 mammary carcinoma. Tumor oxygenation profiles were determined under four conditions: (a) during normal air breathing, (b) during carbogen breathing, (c) after intravenous administration of a solution of ultrapurified polymerized bovine hemoglobin with normal air breathing and (d) after intravenous administration of a solution of ultrapurified polymerized bovine hemoglobin with carbogen breathing. Both tumors had severely hypoxic regions under normal air-breathing conditions. Although carbogen breathing increased the oxygenation of the better-oxygenated portions of the tumor, it made no impact on the severely hypoxic tumor regions. Administration of the hemoglobin solution was effective in increasing the oxygenation throughout both tumors under normal air-breathing conditions. The addition of carbogen breathing to administration of the hemoglobin solution eliminated severe hypoxia in the 9L gliosarcoma and markedly reduced the severely hypoxic regions of the 13672 mammary carcinoma. At 24 h after administration of the hemoglobin solution the 13672 mammary carcinoma showed greater hypoxia than before treatment, which was partially corrected with carbogen breathing.

Abstract
The 9L gliosarcoma growing subcutaneously in the hind leg of the Fisher 344 rat contains major areas of severe (< 5 mmHg) hypoxia, making up about 49% of the tumor. Intravenous administration of an ultrapurified polymerized bovine hemoglobin solution (8 ml/kg) along with normal air breathing reduces the percentage of severe hypoxia to about 24% and increases oxygenation throughout the tumor. Coadministration of the hemoglobin solution increased the tumor growth delay of subcutaneously implanted 9L tumors treated with carmustine (BCNU), cyclophosphamide, or ifosfamide but did not significantly change the tumor growth delay produced by cisplatin (CDDP). Coadministration of the hemoglobin solution with each of the four antitumor alkylating agents resulted in a near doubling of the percentage of increase in life span in animals bearing intracranial tumors treated with the combination as compared with animals treated with the drugs alone. Increases in serum blood urea nitrogen (BUN) and creatinine levels in treated animals returned to normal by 11 days posttreatment. Major changes in liver enzymes occurred with the combination of cyclophosphamide and the hemoglobin solution at 4 days posttreatment; however, these values returned to the levels in the untreated control animals within 1 week thereafter. These results indicate that further exploration of the use of hemoglobin solutions in cancer therapy is warranted.

Abstract
Polymerized bovine hemoglobin solutions (PBHS) are being actively investigated as blood substitutes. In studies analogous to those we conducted with perfluorochemical emulsions/carbogen, we have examined the effect of PBHS +/- carbogen (95% O2, 5% CO2) breathing on the antitumor efficacy of melphalan, cyclophosphamide, N,N'-bis(2-chloroethyl)-N-nitrosourea (BCNU) and cis-diamminedichloroplatinum(II) (cis-platin). The tumor growth delay of the FSaIIC fibrosarcoma treated with melphalan (10 mg/kg), cyclophosphamide (150 mg/kg), cisplatin (10 mg/kg) and BCNU (15 mg/kg) was increased about 2.2-fold, about 2.1-fold, about 1.2-fold and about 1.5-fold, respectively, when PBHS (12 mg/kg) was administered i.v. before each drug was injected i.p. The tumor growth delay produced by each drug was further increased when carbogen breathing for 6 h was allowed after administration of the drug and PBHS. In tumor cell survival experiments 24 h following drug treatment, the addition of PBHS increased the tumor cell killing of both melphalan and cyclophosphamide by about a factor of 10 at the lowest doses of each drug tested (10 mg/kg for melphalan and 100 mg/kg for cyclophosphamide) compared to the drug alone. However, at higher drug doses this effect was lost. The toxicity of each antitumor agent toward bone marrow (granulocyte/macrophage-colony-forming units) was increased 2- to 3-fold by the combined treatment. These results suggest that use of PBHS +/- carbogen breathing may add significantly to the efficacy of antitumor alkylating agents, however, the in vivo/in vitro data suggest that there will be increased bone marrow toxicity with this approach. This needs to be taken into account in the design of clinical trials.

Abstract
When tested in mice bearing the Lewis lung tumor with 2, 3, or 4 Gy daily for 5 days, SBHS produced a dose-modifying factor of 1.6 that was increased to 2.1 with carbogen. The addition of SBHS (1.32 gm protein/kg) to treatment with melphalan (MEL) resulted in a 2.2-fold increase in the tumor growth delay (TGD). The combination of SBHS with carbogen (6 h) produced a 3.6-fold increase in TGD compared with MEL alone. The addition of SBHS to treatment with cyclophosphamide (CTX) resulted in a 2-fold increase in the TGD. However, the combination of SBHS and carbogen was much more effective resulting in a 4.6-fold increase in TGD. There was a 1.3-fold increase in TGD with SBHS and CDDP compared with CDDP alone. The combination of SBHS and carbogen was a more effective addition to CDDP resulting in a 1.9-fold increase in TGD. The addition of SBHS to treatment with BCNU increased the TGD produced by BCNU by 1.5-fold. The combination of SBHS/BCNU and carbogen resulted in a 2.3-fold increase in TGD over that obtained with BCNU alone.

Abstract
Attempts to correct tumor hypoxia with oxygen-carrying solutions have used high concentrations of inspired oxygen (FiO2 100% or 95%). In the clinic, however, obtaining such high levels of FiO2 using mask ventilation in older patients or in children may be difficult. Since lower levels of FiO2 had not been previously tested, we examined the antitumor efficacy of FiO2 levels of 65, 85, and 95% breathed for 1 hr prior to and during irradiation used with the concentrated perfluorochemical emulsion F44E, the less concentrated emulsion, Fluosol-DA, or a new preparation consisting of purified bovine hemoglobin solution, PBHS. When tested in mice bearing the Lewis lung carcinoma with 2, 3, or 4 Gy daily for 5 days, daily Fluosol-DA produced only a small increase in the slope of the tumor growth delay versus irradiation alone, when used with 85% FiO2 (dose modifying factor [DMF] 1.3), but produced a DMF of 2.1 with 95% FiO2. Various concentrations of F44E (2, 4, or 8 g PFC/kg) each required a 95% FiO2 for full effect but the 8 g/kg dose had a discernable effect with an FiO2 of 65% and 85% (DMF 1.25 and 1.30, respectively). For PBHS, in contrast, a DMF of 1.6 was observed at 20% FiO2, but surprisingly this increased further to 2.1 with 95% FiO2. Further investigations of PBHS with irradiation demonstrated that daily administration of PBHS (12 ml/kg) 1 hr before single Xray fractions of 5, 10, 15, or 20 Gy with 20% FiO2 resulted in a DMF of 1.6-1.7 in the FSaIIC fibrosarcoma compared with irradiation alone when ascertained by tumor cell excision assay. These results indicate that to achieve maximum antitumor benefit with these oxygen-carrying solutions with radiation therapy, care must be taken to insure that FiO2 levels near 100% are achieved.

Abstract
1. The whole oxygen dissociation curve of oxyhemoglobin has been determined in double-muscled cattle of the Belgian White Blue breed and in Friesian cattle of different body weight. 2. In calves, P50 values are low and DPG level is high (4-20 mumol/g Hb). 3. P50 values of 25 +/- 1.4 mm Hg (mean +/- SD) and a level of DPG less than 1.5 mumol/g Hb have been found in animals weighing more than 80 kg. 4. Effects of temperature and pH on the oxygen dissociation curve have been measured at all levels of saturation. The temperature coefficient (dlog P50/dT) and the Bohr effect expressed as dlog P50/dpH were 0.017 and -0.40, respectively. 5. Hematocrit, hemoglobin concentrations and oxygen capacity of hemoglobin have been measured. 6. No difference between both breeds has been observed. 7. These data can be used to correct measured values of oxygen tension for temperature and pH and to measure oxygen content of blood in cattle.

Abstract
Using a thin film, dynamic recording technique, the pH sensitivity of the oxygen equilibrium (Bohr effect) of whole blood in the frog Rana temporaria, and its dependence on CO2 and fixed acids and on plasma and erythrocyte pH values were measured. Under standard conditions (20 degrees C, PCO2 = 14.7 mm Hg, pH = 7.65) the oxygen equilibrium could be described by a P50 value of 38 mm Hg and n50 of 1.8 Hill plots of the oxygen equilibria showed increased cooperativity in oxygen binding with increasing saturation (n20 congruent to 1.2, n80 congruent to 4.0). Values of fixed acid and CO2 Bohr factors (phi AH and phi CO2, respectively) were similar at specific saturations (S20, 50, 80) but showed saturation dependence with high values occurring at high saturation. The same statements also hold for the intracellular Bohr factors (derived from the relation between blood P50 and erythrocyte pH) although the values of both phi AH and phi CO2 now were greater than those related to blood pH.

Abstract
We investigated oxylabile H+ binding and pH dependent oxygen binding of adult and newborn bovine hemoglobin as influenced by the organic phosphates 2,3-disphosphoglycerate (DPG), adenosine-5'-triphosphate (ATP), and myoinositol hexaphosphate (IHP). The oxygen affinity of newborn bovine hemoglobin is higher than that of adult hemoglobin over a pH over a pH range of 6.5 to 8. Both DPG and IHP decrease the oxygen affinity of adult bovine hemoglobin. IHP not only decreases the oxygen affinity, but also reduces the apparent cooperativity, whereas DPG does not affect cooperativity. The rise in logP50 upon addition of DPG is about equal for adult and newborn bovine hemoglobin: at pH 7.0 we find delta logP50 values of 0.14 and 0.13 respectively upon addition of a fivefold excess of organic phosphate. This agrees with the identical nature of the presumed organic phosphate binding site in these two hemoglobins, but contrasts with the situation in man: newborn human hemoglobin is much less influenced by organic phosphates than adult human hemoglobin.
