Description:
Background: Food additives are widely used in energy drinks and when taken above acceptable
daily intake leads to various neurodevelopmental toxic effects. The present study aimed to
evaluate the neurodevelopmental toxic effects in rat pups after pre and postnatal administration
of selected food additives in pregnant animals.
Methods: Pregnant rats aged 160-180 days were divided into six groups with four animals per
group. Group 1 treated with vehicle, group 2 standard (caffeine 25 mg/kg p.o.), groups 3-6 were
treated with glucuronolactone (5 mg/kg p.o.), taurine (8 mg/kg p.o.), gluconolactone (84 mg/kg
p.o.), and combination of food additives respectively till postnatal day (PND) 15. After PND 21,
pups were evaluated for neurobehavioural parameters using the behavioral alteration test, Morris
water maze test, locomotor activity test, Y-maze test, hot plate latency and neurobehavioural
scoring. Neurotransmitters were estimated in brain tissue extract on PND 30, 45 and 60 and
histological observations were examined in the brain cortex region.
Results: Food additive treated groups showed an increase in behavioral activity, escape latency,
immobility, percentage of alterations, hot plate latency and neurobehavioural scoring at selected
dose and combination compared to control (p<0.001). The decrease in neurotransmitter levels in
the brain and marked degeneration of neurons in the cortex were observed significantly in group
6 pups.
Conclusion: The present results corroborate that food additives in combination induced
neurodevelopmental toxic effects further mechanistic studies are suggested to understand the
synergistic effect.
