PO2-Profiles in Human Muscle Tissue as Indicator of Therapeutical Effect in Septic Shock Patients
Septic shock is characterized by an impaired cell metabolism. In the early, hyperdynamic phase of septic shock, the cells are prevented from properly utilizing oxygen, glucose, etc. instead of an adequate supp...

Continuous Intra-Arterial PO2 Monitoring During Thoracic Surgery
Anesthesia and surgery, especially thoracic surgery, can have negative effects on oxygenation. It is therefore necessary to monitor arterial oxygen partial pressure (paO2) closely. Conventionally, this is done by...

Factors that Determine the Oxygen Supply of the Cell and their Possible Disruption
Oxygen transport to tissue and cell occurs in three major steps:
-
oxygen uptake in the lung;

Myocardial Oxygen Supply under Critical Conditions, the Effects of Hemodilution and Fluorocarbons
Acute myocardial ischemia continues to be a major cause of morbidity and mortality in spite of considerable advances in the prevention and treatment of this condition. Ischemia is characterized by an imbalance...

Chapter
Cardiovascular Responses, Hemodynamics and Oxygen Transport to Tissue during Moderate Isovolemic Hemodilution in Pigs
As postulated, acute isovolemic hemodilution induces a decrease in systemic vascular resistance (SVR) almost parallel to the decrease in blood viscosity, whereas cardiac index (CI) increases significantly with...

Haemodilution and Myocardial Ischaemia — Studies with Fluorocarbons and Dextran in Pigs
Myocardial ischaemia in surgical patients is an important risk factor, particularly if the patient has suffered recent myocardial infarction; cardiac reserves are compromised then, and tissue oxygen flux may b...

Tissue Oxygen Tension in the Cerebral Cortex of the Rabbit
For the normal function and survival of an organism, a continuous supply of energy is necessary. Without energy nearly all physiological processes, such as electrolyte pum**, could not take place; in other w...

Myocardial Oxygen Tensions during Ischaemia in Fluorocarbon Diluted Pigs
Fluorocarbons are inert compounds with a very high solubility for oxygen which over the last few years have been available in emulsified form in the oxygen transporting plasma substitute Fluosol-DA 20%. This p...

Chapter
Prophylaxis and Treatment of Myocardial Ischaemia by Haemodilution with Fluorocarbon Emulsions
Fluorocarbons (PFCs), largely inert chemicals with a high solubility for respiratory and other gases, are available in emulsified form in the plasma substitute Fluosol-DA 20% (FDA). This has an oxygen solubili...

Changes in Intramyocardial Oxygen Tensions during Hypothermia in Pigs
Hypothermia is firmly established as a therapeutic measure in open heart surgery. The effects of hypothermia on the body were noted as early as 1798 when James Currie of Liverpool treated patients with fever b...

Microphysiological Studies on Oxygenation of Normal or Ischaemic Myocardium
This paper contains some observations on the state of oxygenation of myocardial tissue that were obtained during studies on the collateral supply of oxygen during haemodilution and during the production of myo...

The Effects of Acute Ischaemia on Intramyocardial Oxygen Tensions
Most of the studies of myocardial oxygen tensions (PmO2) that have been performed in the beating heart have been carried out in dogs (Rude et al 1982, Rude et al 1984, Moss 1968, Schuchhardt 1985, Reyes et al 197...

Oxygen Tension in the Pre-Ovulatory and Non-Ovulating Ovarium Follicle of the Rat
In 1978 Edwards and Steptoe were the first to fertilise an oocyte in vitro. Successful reimplantation of the embryo has subsequently led to the birth of the first “test tube” baby. This procedure has been repe...

Oxygen Supply to the Myocardium
This paper concerns aspects of oxygenation of the myocardium in relation to coronary artery flow and in relation to areas of ischaemic hypoxia. These results were obtained during the course of experiments desi...

Tissue Oxygenation by Fluorocarbons
Fluorocarbons have a very high solubility for oxygen and this was very dramatically shown by Clark and Gollan (1966), when they were able to demonstrate survival of mice completely immersed in these liquids fo...

Summary and Conclusions
In this final chapter, we will discuss some of the important findings of our investigation and take the liberty of formulating a few conclusions that are not, as yet, based on hard empirical evidence, but may ...

Introduction
Research into interlocking directorates and other organizational ties between large corporations dates back to the beginning of the century. In Germany and the United States interlocking directorates became an...

Chapter
Between Market and Hierarchy
In Section 1.1 the development of an intricate network of interlocking directorates was explained in terms of Hilferding’s theory of finance capital. In this theory, which firmly stands in the classical marxis...

The International Corporate Elite
Even though the study of interlocking directorates is basically a study of intercorporate power which cannot be based on theories and evidence of intracorporate power, the structure of the corporation is importan...
