ABSTRACT

The continued progression of neurodegeneration may result in dementia. The present study compared the neuroprotective activities between soybean and tempeh extracts in rats. The extracts were administered orally at 10, 20 and 40 mg/kg for 15 days. Radial arm maze and elevated plus maze served as exteroceptive behavioural models for memory measuring. Brain cholinergic activities (acetylcholine and acetylcholinesterase) and neuroinflammatory related cytokines interleukin 1β and interleukin-10 were also tested. Soybean and tempeh extracts significantly improved memory, but overall 40 mg/kg tempeh showed better improvement (p<0.05). The tempeh extracts at 20 and 40 mg/kg exhibited a significant (p<0.05) increase and decrease in the level of acetylcholine and acetylcholinesterase activities, respectively. Tempeh extract (40 mg/kg) resulted in greater reduction (p<0.05) of inflammation than soybean extract. Altogether, tempeh extract may be beneficial in the management and prevention of dementia and Alzheimer’s disease.

ABSTRAK

Neurodegradasi yang berlanjutan boleh menyebabkan penyakit demensia. Kajian ini membandingkan keupayaan ekstrak soya dan tempeh untuk melindungi otak menggunakan tikus. Ekstrak tersebut telah diberi secara oral pada 10, 20 dan 40 mg/kg selama 15 hari. Pengukuran daya ingatan dijalankan dengan menggunakan pagar sesat bentuk jejari dan pagar sesat bersilang tinggi yang merupakan model rangsangan persekitaran. Aktiviti kolinergik otak (asetilkolina dan asetilkolinesterase) dan sitokin yang berkaitan dengan keradangan otak IL-1β dan IL10 turut diuji. Ekstrak soya dan tempeh mampu meningkatkan daya ingatan, namun 40 mg/kg ekstrak tempeh menunjukkan peningkatan daya ingatan yang paling ketara (p<0.05). Ekstrak tempeh (20 dan 40 mg/kg) menunjukkan peningkatan dan penurunan yang berkesan (p<0.05) dalam aktiviti asetilkolina (p<0.05) dan asetilkolinesterase. Ekstrak tempeh 40 mg/kg mengurangkan keradangan (p<0.05) yang lebih ketara berbanding dengan ekstrak soya. Sebagai kesimpulan, ekstrak tempeh mungkin berkesan mencegah demensia dan juga penyakit Alzheimer.

Kata kunci: Daya ingatan; kolinergik; radang otak; soya; tempeh
