The mitotic activity of regenerating liver cells after a single dose (430 r) of x-ray irradiation was studied. In every group of the experimental animals (white rats), the mitotic activity (mitotic index) and the number of abnormal mitotic figures were determined. The results indicated that resting cells irradiated a short time before mitotic activity showed reactions similar to those of cells ...
Phytohemagglutinin (PHA) is a lectin, obtained from the red kidney bean that binds to the membranes of T-cells and stimulates metabolic activity, cell division, etc. The object of this research was the comparison between self made PHA (Indigenous) and imported commercial one, following conventional and High Resolution Cell Synchronization technique (HRCS) .From each blood sample of healthy indi...
Colcemid (COM) and econazole (EZ) were tested for induction of mitotic arrest and C-mitotic effects in mouse bone marrow cells and for meiotic delay and induction of hyperploidy in mouse spermatocytes after single injection. Doses of 1 and 3 mg/kg COM were used and bone marrow and spermatocytes were sampled at 2, 6, 10, 14 and 18 h. For EZ a dose of 120 mg/kg and intervals of 6, 10, 14 and 18 h...
