The biochemical and cytochemical effects of cytosine arabinoside (Ara C) and of hydrocortisone on HeLa cell in vitro have been studied. In cultures treated with Ara C, a relationship exists between the cytocidal effects of the drug and an increase in alkaline phosphatase. Although hydrocortisone had no influence on the proliferative rhythm, it induced an increase in alkaline phosphatase. Results obtained with the cytochemical technique were evaluated, particularly in relation to enzyme localization. |
