Purification of poliovirus labeled with radiophosphorus

Virology, 1958
Abstract Strain MEF-1 of poliovirus was labeled by propagating the virus in monkey kidney cell cultures in the presence of inorganic P 32 . Most of the nonviral P 32 in the lysates was removed by dialysis, followed by ion exchange chromatography, and then sedimentation of the virus.

Leukocyte labeling with inorganic radiophosphorus

American Journal of Physiology-Legacy Content, 1961
Plasma clearance of inorganic P32 given in a single intravenous injection has been evaluated. Significant levels of activity persist for at least 7 days following injection of only 2 µc/kg. Inorganic P32 uptake into various fractions of circulating leukocytes and into fractions of marrow cells has been studied.

DIFFERENTIAL RADIOPHOSPHORUS UPTAKE OF LENS

Archives of Ophthalmology, 1954
THE PRESENCE of lens epithelium on the anterior lenticular surface only has led to speculations concerning the possibility of posteroanterior nutrient flow through the lens. Besides the obvious physiologic importance of such a nutrient flow, there exist many pathologic implications—for example, it would be attractive to consider cataract as a sequel to

An Apparatus for the Intravenous Administration of Radiophosphorus

Physics in Medicine and Biology, 1960
The note describes a shielded assembly for the extraction of radioactive phosphorus solution from an Amersham bottle and the administration to a patient. The risk of spilling of solutions and contamination are minimized.

EVALUATION OF RADIOPHOSPHORUS THERAPY IN PRIMARY POLYCYTHEMIA

Journal of the American Medical Association, 1951
During the past decade, radiophosphorus has become a widely accepted agent for the treatment of primary polycythemia, and favorable experience with it has been reported by a number of investigators.1 In the eight year period from Jan. 1, 1942 through Dec. 31, 1949, 199 patients who had primary polycythemia have been treated with radiophosphorus at the

Use of Radiophosphorus for Bone Vascularity Determinations

Archives of Surgery, 1957
This report presents an attempt to assess some of the problems connected with the use of radiophosphorus as an indicator of bone vascularity. From this account of our experiences with the uptake of radio-phosphorus by rabbit bones, some of the factors emerge which may be causing the observed wide variations in the activity of similar areas in different

Radiophosphorus Measurement of the Lifespan of Lymphocytes in the Rabbit

American Journal of Physiology-Legacy Content, 1957
Measurements of the lifespan of lymphocytes from radioisotope data yield a value of about 2 weeks whereas thoracic duct collection indicates that the circulating lymphocytes are replaced twice daily. In an attempt to reconcile these findings, the relationship of lymphocytes in nodes, thoracic duct and peripheral blood was studied by means of radio ...

Radiophosphorus uptake in chewing and nonchewing teeth

The Journal of the American Dental Association, 1957
Previous studies have indicated that the teeth of experimental animals show cer­ tain variations which may be related to the amount of chewing required by the foods eaten. Thus the molars of rats which were maintained on a liquid diet tended to show a decrease in specific gravity1 and the molars of rhesus mon­ keys fed a soft diet showed a significant ...

Radiophosphorus as the treatment of choice in primary polycythemia

The American Journal of Medicine, 1946
Abstract 1.1. Polycythemia may be primary, secondary or familial. The duration of each differs. The duration of primary polycythemia (polycythemia vera) is probably ten to fifteen years. 2.2. The primitive erythroid elements (normoblasts, etc.) of the marrow probably differ in each of the three entities.
