The effect of adjuvant CMF (cyclophosphamide, methotrexate and 5-fluorouracil) and tamoxifen (TM) on endocrine function was studied in 120 women with stage I-II operable breast cancer. Sixty patients were premenopausal, of whom 25 were treated with CMF for 9 months, 25 received CMF for 9 months + TM for 2 years, started concurrently, and 10 TM alone for 2(More)
Concentrations of numerous sulfate steroids were checked in the plasma of 10 women in normal pregnancy (NP), 21 women with intrahepatic cholestasis of pregnancy (ICP) and 10 pregnant women suffering from viral hepatitis with jaundice (VHP). A considerable increase in 5 alpha pregnane and 5 beta pregnane 3 alpha, 20 alpha diols, mono- and disulfates and in 5(More)
We present cw sum-frequency generation of UV radiation at 355 nm based on a high-power laser at 1064 nm and a two-stage quasi-phase-matching nonlinear interaction in periodically poled LiTaO3 crystals. In a first stage, second harmonic at 532 nm is generated. Then, the outcoming IR and green light interact in a second nonlinear crystal to generate about 7(More)
A comparison of heat-stable enterotoxins from Escherichia coli and Yersinia enterocolitica by the suckling mouse bioassay showed that whereas E. coli heat-stable enterotoxin evoked a maximum ratio of gut weight to remaining body weight after a 4-h incubation period, the maximum ratio for Y. enterocolitica was achieved at 2 h, decreasing thereafter to values(More)
Thermophilic Campylobacter is reported as the agent associated with chronic and acute diarrhoea in Rio de Janeiro. Nine strains were isolated from 186 children with gastroenteritis. To our knowledge this is the first report of human Campylobacteriosis in Latin-America.
Sixty-three patients with severe breast dysplasia were treated with tamoxifen, 10 mg/day from day 5 to day 25 of the menstrual cycle for 4 months. Lesions were assessed by mammography, thermography, and echography (A- and B-mode scanning). In 45 patients (71.43%) there was complete remission of symptoms and disappearance of lesions as assessed by echography(More)
