South Africa: a toxicologist's goldmine.

abstract：:Epilepsy is characterized by seizures recurring at interindividually differing time intervals. It may be difficult to assess drug response if time intervals between seizures are long. Thus, the existence of surrogate parameters that could be used to reliably identify drug efficacy and tolerability at an early stage an...
