Summary
Patulin exhibits both cytotoxic and cytopathic effects on cultured Chang liver cells. The LD50 found was 1.85 μg per ml of patulin. Effects on growth were observed with as little as 0.1 μg per ml of patulin; a 50% reduction in growth was observed at 0.38 μg per ml of patulin. Using a challenge dose of 2.5 μg per ml of patulin, the cytotoxic effect was reversible after an exposure of 10 min, but was not reversible after 20 min. Protein synthesis was depressed after 60 min and RNA synthesis after 20 min of contact with patulin. Neither protein nor RNA synthesis was completely inhibited after 260 min.
