Microbiological and histological findings in the fallopian tubes of women using various contraceptive methods.

The oviducts of seventy-three women undergoing sterilization by partial salpingectomy were submitted for microbiological and histologic studies. Twenty women were intrauterine device users, twenty-five women were oral contraceptive pill users and twenty-eight women used natural or barrier methods of contraception. Among intrauterine device users, there was an excess of mild and severe acute inflammatory histologic changes involving both the lumen and the tubal mucosa. Five of the eight intrauterine device users with acute inflammatory change had sterile tubal cultures.

Quantitative aspects of the E2 receptor assay for human breast tumour cytosol using dextran-coated charcoal.

Misclassification of the oestrogen status of a human breast tumour cytosol, arising from different sources and magnitudes of error in the dextran-coated charcoal (DCC) method, have been investigated using both practical and computer simulated data analysed by Scatchard and Mass Action models. The minimum detectable receptor site concentration, relative or absolute numerical bias and imprecision which are complex and integral functions of misclassification, have been calculated from practical data and for a range of experimental conditions likely to be encountered in practice. The Mass Action model was found to be superior and the computer program, designed to investigate the effects of methodological errors on quantitative aspects of the assay, may be a useful aid for analytical design and internal quality control of the receptor assay.

In response to continuing increases in health care costs, big business has begun to lower the boom on hospitals and physicians through outside utilization review. Physicians, however, are seen as the key to controlling costs.
