There was complete correlation among the 3 methods in 62 per cent of the cases, All but 1 of these concordant cases had neoplasms positive for estrogen receptor_ Of the nonconcordant cases 5 with negative results by the dextran-coated charcoal method had differentiated infiltrating tumors, including 3 in whom the dextran-coated charcoal method agreed with 1 of the other techniques. Immunoperoxidase alone was negative in 4 cases and fluorescein-labeled estradiol conjugate alone was negative in L No correlation was seen between histologic tumor type or location and receptor content. However, only small numbers of less common breast tumor types were included_ A majority of poorly differentiated tumors were positive by all techniques, The case of lymphoma was negative all methods_ M.

Gentamicin has a broad spectrum of activity against gramnegative and gram-positive bacteria, and it often is used to treat urinary tract infections. Gentamicin is excreted memlar filtration into the urine where levels several fold greater than serum are reached. owing to tissue binding gentamiein is detected in the urine for a µ,aJ1uu.-;eu interval after single dose administration. The authors studied the concentration and antibacterial of gentamicin in concentrated and dilute urine after a single dose in They found that the minimal bactericidal concentration of gentamicin ln dilute urine vvas lower than in the concentrated urine. Doses smaller than those used for infections should suffice in the treatment of tract infections. Therefore, ulation of urinary osmolality and pH 1s to affect the success of therapy. N. V.
