Anaesthesia for radiotherapy under high-pressure oxygen.
FOLLOWING experimental work on animals it has been suggested that the effectiveness of X-ray treatment of tumours may be increased by the simultaneous administration of oxygen under high pressure (Gray et al., 1953). To determine if these results were applicable to be made much more radiosensitive by increasing the oxygen tension. Many tumours, however, contain large numbers of cells which, bec...
متن کاملTreatment of Neo-vascularization with Oxygen at High Pressure.
(1) It has long been known that the vessels of the central nervous system, including those of the retina, are sensitive to the ambient oxygen concentration. Cusick, Benson, and Boothby (1940) were able to show that there was a considerable reduction in the calibre of the retinal vessels in the normal subject who breathed pure oxygen for short periods, and Sieker and Hickam (1953) have shown tha...
متن کاملHigh pressure insulator-metal transition in molecular fluid oxygen.
We report the first experimental evidence for a metallic phase in fluid molecular oxygen. Our electrical conductivity measurements of fluid oxygen under dynamic quasi-isentropic compression show that a nonmetal-metal transition occurs at 3.4 fold compression, 4500 K, and 1.2 Mbar. We discuss the main features of the electrical conductivity dependence on density and temperature and give an inter...
متن کاملInteractions of Oxygen at High Pressure and Radiation in Drosophila
Oxygen at high pressure (OHP) and X-irradiation can interact in the fruit fly Drosophila melanogaster to potentiate toxic actions characteristic of one agent alone. 1000 kvp X-irradiation in doses of 30, 60, and 75 kr accelerated the acute immobilization of young male Drosophila by oxygen at 7.8 atm, up to rates twice that observed with such oxygen pressure alone. X-irradiation alone in these d...
متن کاملCollective spin 1 singlet phase in high-pressure oxygen.
Oxygen, one of the most common and important elements in nature, has an exceedingly well-explored phase diagram under pressure, up to and beyond 100 GPa. At low temperatures, the low-pressure antiferromagnetic phases below 8 GPa where O2 molecules have spin S = 1 are followed by the broad apparently nonmagnetic ε phase from about 8 to 96 GPa. In this phase, which is our focus, molecules group s...
