DefinitionSynergic effect VS. Additive effect

Synergic effectThe interaction of two or more agents or forces so that their combined effect is greater than the sum of their individual effects.

Additive effectAn effect in which two substances or actions used in combination produce a total effect the same as the sum of the individual ef-fects.

Synergic effect of anti-con-vulsant agents and regular exercise on kainic acid in-

duced seizure

Introduc-tion

What is seizure ?"Seizure" is a general term that refers to a sudden malfunction in the brain that causes someone to collapse, convulse, or have another temporary disturbance of normal brain function, often with a loss or change in consciousness.

Purpose

The purpose of this study was to investigate the synergic effect of regular exercise and therapy with an anticonvulsant agents could be a more efficient method for the prevention and/or treat-ment of epilepsy than exercise alone.

Materials and Methods

Drugs

Kainic acid (30 mg/kg; i.p.) to induce seizure activity

Resveratrol (250 mg/kg, orally) - a type of nat-ural phenol

Riluzole (5 mg/kg, i.p.) - a potent neuroprotec-tive drug

Clonidine (4 mg/kg, i.p.) - α2 adrenoreceptor agonist

Adult male ICR mice weighing approximately 35 g each (8 week-old)

Materials and Methods

Physical exercise train-ing6 weeks swimming training (60 min sessions, 5 times per week)1st week: adaptation to swimming without weights

After the water-adaptation period, the mice were made to swim with weights (5% of body weight) in order to improve endurance exercise capacity. (Arida et al., 1991).

These results indicate that the combina-tion of regular exercise and therapy with an anticonvulsant agent could be a more efficient method for the prevention and/or treatment of epilepsy than exercise alone.

Conclusion

Implication & Future Direction Potential synergistic effect of diet and exercise in

the prevention and treatment of chronic diseases.

Mechanisms of action and optimal diet and exer-cise prescription needed for benefit remain elusive. Nutrients are directed to specific tissues and cells via

physiologic processes that require much more research

Need to understand how diet (drug) and exercise interact to promote health, how changes in one af-fect the other.

What comprehensive prescription will be optimal in disease prevention?
