Actinomycin D affects a number of functions of the epithelial cells of the small intestine. Maltase, saccharase and lactase levels in the small intestine of hamsters treated with various dosages of actinomycin D over various periods of time, differed from those observed in control animals: administration of 0.25 micrograms/g body weight, gave rise to a statistically significant increase in the maltase and saccharase levels measured after 4 h and a statistically significant reduction in the lactase levels measured after 8 h; administration of 1.5 micrograms/g body weight reduced the activity of all three enzymes at all times post-administration, the decrease being statistically significant for maltase after 2 and 8 h.

Actinomycin D, at a dose of 0.25 micrograms/g body wt, produced slight increases in intestinal enzymatic activity on hamsters. At a high dose (1.5 micrograms/g body wt), actinomycin D produced inhibition of lactase activity, whereas maltase, sucrase and alkaline phosphatase activity decreased in males and increased in females. Cycloheximide (1.5 micrograms/g body wt), produced no changes in enzymatic activity. In the male and female hamster, the different actions of the antibiotic can be explained by the variations in the cortisol release produced by stress.
