Gambaran Histopatologik Hati Tikus Wistar (Rattus Norveginus) Yang Diinduksi Monosodium Glutamate (MSG) Dan Diberikan Sari Air Bawang Daun (Allium Fistulosum L.)

: Monosodium glutamate (MSG) has been consumed around the world as a food additive in the form of L-glutamic acid. The liver has glutamate receptors, hence its susceptibility to damage due to oxidative stress from consuming excessive MSG. Leek contain antioxidants such as flavonoid, which has potent hepatoprotective properties under certain liver conditions, for the example, oxidative stress, liver fibrosis, and fatty liver. This study aims to see the liver histopathologic findings of wistar rats (Ratus norvegicus) that has been induced by MSG and was given leek juice (Allium fistulosum L.). This was an experimental laboratory study, with 20 wistar rats as subjects. In this study, 173,6 mg per gram body of monosodium glutamate and 20 gram per kilogram body weight of leek juice are administered orally each day. Group A is the negative control group. Group B is given MSG for 14 days. Group C are given MSG for 14 days and were stopped for 5 days. Group D are given MSG for 14 days and were given leek juice. Group A shows normal liver histopathologic features. Group B shows liver cells damage in the form of inflammation and fatty cells. Group C shows regeneration of liver cells but a little bit of inflammation and fatty cells were still found, while in group D there is a wide regeneration of liver cells and there was barely any inflammation and fatty cells. Conclusion: Microscopic features of wistar rat liver after administration of monosodium glutamate for 14 day showed inflammation and fatty cells and then the administration of leek juice for 5 days after MSG administration oon wistar rat showed a wide regeneration of liver cells compared to no administration of leek juice
