The development of Ascaris suum eggs in the culture containing prostaglandins (PGA, PGB, PGE and PGF) or inhibitors of their synthesis (indomethacin and acetylsalicylic acid) was studied. Exposure of eggs to indomethacin (0.2 and 0.5%) or acetylosalicylic acid (1 %) delayed the development. 0.5% acetylsalicylic acid didn't exert any effect. The development was also delayed by PGB, PGE, PGF and higher concentration of PGA. But lower concentration of PGA accelerated embryonic development.
