The specificity and application of a radioimmunoassay for the alpha-subunit of luteinizing hormone in man.

A sensitive radioimmunoassay for the alpha-subunit of LH has been developed. Differences in the immunopotency of LH, FSH, and subunit preparations were found and are described in detail. The assay has been applied to the measurement of circulating levels of alpha-subunit; higher levels of alpha-subunit were found in post-menopausal than in pre-menopausal women, or men, and a rise in alpha-subunit was seen after LH-RH but not TRH administration.

Polycythemia vera treated with -32p and myleran: development of chronic granulocytic leukemia with chromosomal abnormalities in one patient.

Chronic granulocytic leukemia developed in a 59-year-old woman who had previously received a total of 21 mCi -32P for polycythemia vera. She was treated with Myleran (busulphan) for her chronic granulocytic leukemia. Cytogenic studied revealed deletion of chromosomes No.

Survival of bacterial isolates exposed to simulated Jovian trapped radiation belt electrons and solar wind protons.

With missions to Jupiter, the spacecraft will be exposed for extended durations to solar wind radiation and the Jovian trapped radiation belt. This study is designed to determine the effect of these radiation environments on spacecraft bacterial isolates. The information can be used in the probability of contamination analysis for these missions.
