Forty-nine patients were treated with either 3 x 75 MBq 89Sr or saline as placebo. Analysis of results 1 to 3 years after therapy revealed the ineffectiveness of 89Sr to relieve pain from metastases. Unexpectedly, a higher survival rate was found after Sr application (46% vs 4% after 2 years). Covariate analysis underlines the effect of 89Sr therapy on life expectation.

Summary The storage life of lard was increased by heating it under vacuum to 288–296°C. with 0.1 to 0.5% of various protein and carbohydrate materials (dried whey was the most effective substance used), but undesirable color and odor were produced in the lard by the process, and bleaching and deodorizing to a bland, light colored end‐product resulted in a loss of most of the added stability.

SUMMARY Irradiation (Cow source) of solutions of DL‐a‐tocopherol caused extensive destruction of this vitamin and gave rise to products similar to those obtained by autoxidation. Irradiation in saturated solvents (mineral oil, methyl myristate) destroyed more tocopherol than did irradiation in unsaturated solvents (methyl oleate, methyl linoleate). Destruction by 2.0 Mrad of irradiation increased with increasing tocopherol concentration, but the increase became negligible above 0.5% tocopherol in the saturated and 0.1% tocopherol in the unsaturated solvents.

Summary The stability ofd‐a‐tocopherol in stable solvents and in methyl esters of fatty acids varied with the stability of the medium and with the concentration of tocopherol. Pure tocopherol was less stable than tocopherol in solvents. The concentrations of tocopherol that were most effective in delaying rapid oxidation of the esters were also best for stability of tocopherol itself. The rate of destruction of tocopherol could not be described by simple kinetics.
