Summanr This study u-as aimed at determining whether tumour DNA content measured bv cell image analysis could proVide additional prognostic information when compared to that proVided bv flow cytometry. Sections cut from paraffin blocks of tumours from 101 patients with node negative breast cancer were analysed by both methods and the results related to other prognostic variables and to patient ...

Biological markers to confirm diagnosis and monitor the therapy in multiple sclerosis patients.

In patients suspected of multiple sclerosis (MS), even in the case of MRI positive changes, cerebrospinal fluid (CSF) analysis is of great practical value. Until now, however, only IgG index, restricted oligoclonal IgG bands and the examination of IgG subclasses have been of practical value. The determination of other immunological markers is too expensive to be introduced into laboratory diagn...

Introduction: Session on Metabolism

Introduction to toxicity evaluation session.

There have been invented innumerable chemical substances which enter living organisms, including humans. These may damage the liver, preserve the teeth, damage the fetus, induce cancers, cure trivial and serious diseases, destroy vermin, prolong life, increase the quality and quantity of the food supply, preserve the facade of youth for the aging and make instantaneous photographs in vibrant li...

Chairman's Introduction to Session on Bioassay, Risk Assessment and Epidemiology

In irtroducing this third session ofthe Conference, let us pause for a moment to see where we have been in the first two sessions. The descriptive epidemiology of feral fish populations strongly suggests that enzootics ofneoplasms are associated with contamination of their environment with carcinogens, procar-cinogens, and cancer promoters. Detailed biochemical studies on fish and shellfish fro...
