Abstract

Thirty-two female patients with rheumatoid arthritis were divided into 3 groups and treated for 6 months with prednisolone, depot tetracosactrin, or indomethacin. Their whole body content of calcium, phosphorus, and nitrogen was measured before and after 3 and 6 months' treatment by in-vivo neutron activation analysis. No significant changes in these body elements were observed as a result of the treatments. The average amounts of calcium, phosphorus, and nitrogen were lower than normal in these patients, a finding consistent with the frequent observation of osteoporosis and muscle wasting in rheumatoid arthritis.

36. A less empirical method of representing megavoltage beams for use in rapid radiotherapy dose calculations

Author

Haywood, J. K., Bomford, C. K., and Hatton, J. A.

Abstract

A large number of initial measurements are needed for accurate computation of radiotherapy dose distributions directly from stored data on the dose distributions of single radiation beams. Because of this, interest has been shown in alternative methods which use empirical formulae to represent the dose distributions of single beams. These can be easier to implement but are less directly related to measured quantities and may be of limited validity. A method of representing radiotherapy beams is proposed which closely approximates their radiation physics, in order to calculate the dose at any point by a simple algorithm directly from a small number of initial dose measurements. The method is of wide validity, probably including all megavoltage radiations for which Compton scattering is the dominant interaction in tissue. The accuracy of the method is demonstrated by application to an 8 MV linear accelerator and a cobalt 60 machine.

37. Concurrent Estimation of Total Body and Exchangeable Body Sodium in Hypertension

Author

Boddy, K., Brown, J. J., Davies, D. L., Elliott, A., Harvey, I., Haywood, J. K., Holloway, I., Lever, A. F., Robertson, J. I. S., and Williams, E. D.

Abstract

1. Total-body neutron-activation analysis in vivo was carried out in 11 hypertensive subjects to measure simultaneously the total body content of sodium, chlorine, calcium, phosphorus and nitrogen. 2. There was a highly significant correlation between total body sodium measured by activation analysis and total exchangeable sodium measured by a standard isotope-dilution technique (r = 0·92, P < 0·001). Exchangeable sodium averaged 80·3% of total body sodium. 3. The measured values of chlorine, calcium, phosphorus and nitrogen were similar to those for healthy subjects reported by others. 4. Activation analysis in vivo appears promising as an additional tool for investigating sodium metabolism in hypertension, as it is the only method available for determining the total body content of this element. The radiation dose (1 rem) is sufficiently low to permit repeated measurements in the same subject.
