Kindled seizure induction alters and is altered by zinc absorption.

Amygdala kindling stimulation produced significant changes in plasma zinc levels in cats otherwise unaffected by zinc loading or deprivation. While a normal diet had no effect, moderate zinc loading was accompanied by a marked increase in plasma zinc during kindling. Conversely, plasma zinc sharply declined in animals fed a zinc-deficient diet. Corresponding differences were obtained in the development of generalized seizures with kindling such that loading delayed and deprivation accelerated this process.
