Abstract
BACKGROUND: The brain is very susceptible to damage from oxidative stress due to undernutrition. Provision of
nutrients and compounds that act as antioxidants is needed to improve oxidative stress in the brain.
AIM: This study was conducted with the aim of proving the potential of the combination of pasak bumi (Eurycoma
longifolia Jack), DHA, and seluang fish (Rasbora Spp.) to improve oxidative stress in the brains of undernourished
rats (Rattus norvegicus).
METHODS: Once the rats were undernourished, they were divided: positive control (KP) = undernourished rats +
placebo + standard feed; (P1) = undernourished rats + 70% ethanol extract of pasak bumi root (EPB) 15 mg/kg BW
+ standard feed; (P2) = undernourished rats + DHA 1 mg/kgBW + standard feed; (P3) = undernourished rats + EPB
15 mg/kg BW + DHA 1 mg/kg BW + standard feed; (P4) = undernourished rats + seluang fish; (P5) = undernourished
rats + EPB 15 mg/kg BW + seluang fish for 5 weeks; plus 1 negative control group (KN) that is healthy rats given
placebo and standard feed. The parameters included superoxide dismutase (SOD) activity, catalase, peroxide
(H2O2) and malondialdehyde (MDA) levels. Data analysis used the Kruskall-Wallis test followed by Mann Whitney
with a significance level of 95%.
RESULTS: There were significant differences in the activity of SOD (p = 0.001), catalase (p = 0.000), peroxide levels (p
= 0.000), and MDA (p = 0.000) between treatments. The group that was given a combination of EPB 15 mg/kg BW and
DHA 1 mg/kg BW showed better SOD and catalase activity, and lower levels of peroxide and MDA than the other groups.
CONCLUSION: The combination of 70% ethanol extract of pasak bumi 15 mg/kg BW and DHA 1 mg/kg BW has
the best potential to improve brain oxidative stress in undernourished rats compared to single administration of
15 mg/kg BW EPB, DHA, or seluang fish alone.
