Frequencies of sperm head anomalies (SHA) and chromosome aberrations (
CA) in bone marrow cells were studied after injection of drugs, prosta
tilene and vitamin C into the male mice Mus musculus. It was found tha
t prostatilene (5, 10 and 50 mkg) increased the frequency of both SHA
and CA. Vitamin C (14 and 140 mkg) induced no CA but increased SHA fre
quency at the dose of 140 mkg. The joint action of the drugs led to de
crease in SHA frequency for all dose combinations. Antimutagenic actio
n of vitamin C in the CA test was recorded for only 14 mkg dose.
