To determine whether the hypothalamo-pituitary axis (HPA) became suppressed in patients with chronic active hepatitis (CAH) treated with prednisone or long-activity synthetic corticotrophin (L.A.S.C.) for at least 12 months 36 patients with CAH were assessed for growth hormone release following insulin hypoglycemia test (IHT). Sixteen out of the 36 patients(More)
Fresh and salt water samples analyzed in Rio de Janeiro city showed the presence of Plesiomonas shigelloides. Forty-six strains were isolated from both environments. A high incidence of P. shigelloides was achieved in polluted fresh and salt waters as well as in samples from non-polluted streams. P. shigelloides isolates had biochemical characteristics(More)
A case of Kallmann's syndrome in a male is reported. Besides the classical picture of hypogonadotrophic hypogonadism (demonstrated both by endocrine investigation and a testicular biopsy) with anosmia, a number of other unusual features are present including gynaecomastia, agencies of the anterior brachial muscles, some dental abnormalities, and(More)
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)
Four experiments are described in which laboratory mice were infected with Y. enterocolitica using an American serotype 0:8 (WA) and two European strains, serotypes 0:3 and 0:9. The pathogenicity and histopathological responses of strain WA (0:8) were determined in the Porton white outbred mouse by three route of inoculation. The LD50 after infection by the(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)
