Pemberian Ekstrak Bayam Merah (Amarantus Tricolor linn) Memperbaiki Ekspresi BDNF dan GLUR1 pada Area Hipokampus Tikus Muda yang Terpapar Anestesi Inhalasi Halothane dan Sevoflurane
Abstract
In the development stage, brain has a higher level of vulnerability than the adult brain to anesthetic agents. The aim of this study was to investigate the effects of red amaranth extract to brain derived neurotrophic factor (BDNF) and AMPA glutamate receptor subunit 1 (Glur1) expressions as biomarkers of cognitive and neuroplasticity in rat hippocampus areas exposed to inhaled anesthetics halothane and sevoflurane. The design of this study was a randomized posttest only control group. This study was conducted at the Department of Biochemistry Faculty of Medicine, Universitas Airlangga, and the anesthetic procedures were performed at the Veterinary Hospital, Faculty of Veterinary Medicine Universitas Airlangga during the period of May–October 2014. The subjects of this study were 23 white male rats (Rattus norvegicus) wistar strain, aged 1–1.5 months, weighted approximately 60–100 grams in a healthy physical condition. The subjects were divided into 5 groups, K (control); K1 (1 MAC halothane); K2 (red amaranth 800 mg/kgBW + 1 MAC halothane); K3 (1 MAC sevoflurane); and K4 (red amaranth 800mg/kgBW+1 MAC sevoflurane). The results of this study showed a decrease in the expression of BDNF when halothane and sevoflurane were administered. Red amaranth treatment prior to anesthetic gases exposure preserved and increased BDNF expression (p=0.000) while GLUR1 expression increased in the group that received halothane and sevoflurane administration and decreased back to normal in the group that received red amaranth treatment prior to exposure to anesthetic gases (p=0.000). In conclusion, red amaranth extract has the potential effect to prevent cognitive neurotoxicity on the cognitive function in rats exposed to anesthetic gases.
