Abstract
Summary
The effects of prolonged exposure to hydrocortisone on the alkaline phos-phatase activity of HeLa, J111, and H. Ep2 cells have been investigated by enzymatic and histochemical methods. Exposure of HeLa cells to hydrocortisone produced a 12.5-fold increase in activity, while exposure of Jill and H. Ep2 cells to the compound caused a 7- and 1.5-fold decrease respectively. The observations are in agreement with those obtained by other investigators using variants of cell strain EUE.
