title: The role of solid food intake in antimuscarinic-induced convulsions in fasted mice.
abstract: Animals treated with scopolamine after fasting develop convulsions after they are allowed to eat ad libitum. This study was aimed at investigating the effect on these convulsions of liquid food intake, feeding by gavage, and placebo. Fasted mice treated with saline or scopolamine were allowed to eat solid food, slurry food or liquid food ad libitum, given placebo, or given liquid food by gavage. After 30 min, all animals were allowed to eat food pellets and observed for 30 min for the incidence and onset of convulsions. Scopolamine treatment caused convulsions only in the animals given solid food in the first 30 min; no convulsions were observed in the animals given slurry food, liquid food ad libitum, gavage, or placebo. When the animals that did not develop convulsions during the experiment were allowed to eat solid food, convulsions occurred. These findings indicate that complex mechanisms trigger scopolamine-induced convulsions in fasted animals eating solid food.
