Tepung Pisang Berlin Unripe Meningkatkan Fungsi Kognitif Tikus Yang Diinduksi High Fat Diet

Konsumsi lemak yang berlebih berdampak pada ketidakseimbangan sistem saraf utamanya pada otak. Pisang berlin unripe atau unripe banana flour (UBF) mengandung magnesium dan flavonoid. Tujuan penelitian yakni untuk mengetahui pengaruh tepung pisang berlin unripe terhadap fungsi kognitif tikus yang diinduksi HFD. Tikus wistar sebanyak 18 ekor dikelompokkan menjadi kelompok tikus normal (K-), kelompok tikus yang diinduksi HFD (K+), dan tikus yang diinduksi HFD+UBF. HFD diinduksi selama 9 minggu dan intervensi UBF diberikan selama empat minggu. Parameter yang diuji yakni kandungan pakan HFD+UBF fungsi kognitif tikus setelah diinduksi HFD (Pretest) dan setelah intervensi UBF (Postest). Pengukuran fungsi kognitif dengan menggunakan labirin. Hasil penelitian menunjukkan bahwa tikus yang diinduksi HFD setelah diberi UBF (posttest) mengalami peningkatan fungsi kognitif dibandingkan sebelum diberi perlakuan UBF (pretest) (P<0,05). Simpulan diperoleh bahwa tepung pisang berlin unripe mampu memperbaiki fungsi kognitif tikus yang diinduksi HFD. Kata kunci: HFD, Kognitif, UBF

Abstract. Objective: This study aimed to evaluate the effect of maternal consumption of flaxseed flour and oil on serum concentrations of glucose, insulin, and thyroid hormones of the adult female offspring of diabetic rats. Methods: Wistar rats were induced to diabetes by a high-fat diet (60%) and streptozotocin (35 mg/kg). Rats were mated and once pregnancy was confirmed, were divided into the following groups: Control Group (CG): casein-based diet; High-fat Group (HG): high-fat diet (49%); High-fat Flaxseed Group (HFG): high-fat diet supplemented with 25% flaxseed flour; High-fat Flaxseed Oil group (HOG): high-fat diet, where soya oil was replaced with flaxseed oil. After weaning, female pups (n = 6) from each group were separated, received a commercial rat diet and were sacrificed after 180 days. Serum insulin concentrations were determined by ELISA, the levels of triiodothyronine (T3), thyroxine (T4) and thyroid-stimulating hormone (TSH) were determined by chemiluminescence. Results: There was a significant reduction in body weight at weaning in HG (−31%), HFG (−33%) and HOG (44%) compared to CG (p = 0.002), which became similar by the end of 180 days. Blood glucose levels were reduced in HFG (−10%, p = 0.044) when compared to CG, and there was no significant difference between groups in relation to insulin, T3, T4, and TSH after 180 days. Conclusions: Maternal severe hyperglycemia during pregnancy and lactation resulted in a microsomal offspring. Maternal consumption of flaxseed reduces blood glucose levels in adult offspring without significant effects on insulin levels and thyroid hormones.
