flow cytometry (fcm) was used to determine the ploidy levels of six different populationsof agropyron cristatum (l.) gaertn. (poaceae) in iran, using a diploid cultivated barley (hordeumvulgare l.) as an internal reference. according to flow cytometric data, tetraploid (2n = ± 28) andhexaploid (2n = ± 42) levels were detected among the examined populations and these results weresupported by chr...

To investigate the patterns of DNA ploidy and proliferating activity in breast cancer and relate them to other prognostic factors, paraffin blocks of 53 cases of breast carcinoma were studied. Cancer cells obtained by mechanical tissue disaggregation were examined for DNA content, ploidy and S-phase fraction. DNA assay was done using a CAS interactive image analyzing system. All of the cas...

Background: Cyclosporine A (CsA) is a powerful immunosuppressive agent, which is used for the prevention of allograft rejection and for the treatment of autoimmune diseases.  Many transplant recipients must take this medicine for the rest of their lives.  Females in reproductive age group on prolonged CsA therapy have legitimate concerns about drug effects on pregnancy. Objective: To explore Cs...

Transitional cell carcinoma(T.C.C) of bladder display an upredictable biological behavior.Morphologic methods of grading this tumor are insuficient to predict the clinical outcome of the patients.the aim of this study was to investigate the relationships between histological grading staging and DAN ploidy especially in intermediate grade II(IIa and IIb). in a retrospective study  of tissue spec...
