Prognostic role of flow cytometry in superficial bladder cancer.

Prognostic factors in superficial transitional cell carcinoma of the bladder were assessed with histopathological and flow cytometry analysis in a series of 61 patients operated transurethrally between 1988 and 1990. In particular, we evaluated the usefulness of flow cytometry in order to identify patients who require a more accurate clinical follow-up or a more aggressive therapy. A multivariate analysis was done in 61 cases, considering patient age and sex, stage, grade and number of lesions (unifocal or multifocal), post-TUR therapy (therapy or not), and DNA ploidy (diploid/aneuploid). DNA pattern and number of recurrences were determinant for selecting risk cases for progression.

[Effect of the unsaponifiables of the most common edible oils on the development of E. coli bacteria]. / Influenza degli insaponificabili dei piu' comuni oli edibili sullo sviluppo del battere E. coli.

The writers within the context of the research on the biological actions of the unsaponificables in the most common edible oils, have tested the effects produced by such unsaponificables on the culture of E. Coli. The unsaponificables, and those of seed oils of peanuts and sunflowers in particular, aid the doubling of the E. Coli. Similar research on the culture of animal cells (in vitro) and unicellular algae, are at present outstanding.

[Interaction between alkaloids of Claviceps purpurea and development of some bacteria and bacteriophages. Preliminary experiments]. / Interazione tra alcaloidi della Claviceps purpurea e sviluppo di taluni batteri e batteriofagi. Esperienze preliminari.

It has been tested the bacteriolytic activity and the interaction among the development of the bacteriophage T4 and Ergot alkaloids. It has been determined a bacteriolytic action on the bacterial stub "E. Coli host of bacteriophage T4. It exist an interaction also among such alkaloids and the development of the bacteriophage T4, which appears through an increase of the quantity of lysis areas, becoming evident in solid bodies containing the lysing bacterium. Further researches with other bacterial and virus stubs will be effected and mentioned afterward.
