Pengaruh pemberian monosodium glutamat terhadap gambaran histologis ginjal mencit galur swiss webster
M onosodium Glutamat (dikenal dengan nama MSG) merupakan salah satu komponenutama terciptanya makanan enak dan lezat. Konsumsi MSG di dunia, termasuk di Indonesia, banyak menimbulkan kontroversi di masyarakat luas. Hingga saat ini, penelitian tentang efek pemberian MSG pada makhluk hidup telah banyak sekali beredar. Di dalam tubuh MSG akan mengalami absorbsi, distribusi, metabolisme, dan ekskresi. Ginjal adalah organ ekskresi utama, sehingga seringkali mengalami kerusakan jika terpapar oleh zat-zat toksik. Tujuan penelitian ini adalah untuk mengetahui adanya pengaruh pemberian MSG terhadap gambaran histologis ginjal mencit.METODEPenelitian eksperimental menggunakan desain Post Test-Only Control Group. Jumlahsampel 30 ekor mencit galur Swiss Webster dengan kriteria spesifik, dibagi menjadi 3kelompok, masing – masing 10 ekor. Kelompok K adalah kelompok Kontrol (hanyadiberikan aquades) dan kelompok P adalah kelompok Perlakuan yang diberi MSG dosisbertingkat (P1 = 3 mg/kg BB dan P2 = 8 mg/kg BB) selama 14 hari. Jaringan ginjal selanjutnya diproses untuk pembuatan preparat histologi dengan pewarnaan Hemaktosilin Eosin (HE). Data dikumpulkan dan dianalisis dengan uji analisis Independent Sample t-Test dan Paired Sample t-Test.HASILTerdapat kerusakan tubulus ginjal berupa penebalan dan peningkatan rata-rata diametertubulus. Uji statistika menunjukkan adanya perbedaan bermakna (p<0.05) antara kelompok proksimal K dan P1; K dan P2, distal K dan P1; K dan P2, berat badan P1; P2. Perbedaan tidak bermakna ditemukan pada kelompok proksimal P1 dan P2, distal P1 dan P2, dan berat badan K.KESIMPULANTerdapat pengaruh pemberian Monosodium Glutamat dengan dosis bertingkat (3 mg dan 8 mg) per oral selama 14 hari terhadap gambaran histologis ginjal mencit galur SwissWebster berupa peningkatan diameter dinding - dinding tubulus renal.
M onosodium Glutamate (known as MSG) is one of the main components in creating great and delicious food. MSG consumption in the world, including Indonesia, has generated a lot of controversies in the wider community. Until now, research on the effects of MSG on living organisms has widely revolved. In the body, MSG will passthrough absorbtion, distribution, metabolism, and elimination. The kidneys are theprincipal organs for elimination, therefore, they have most likely suffered damage to theexpotion of toxic substances. The purpose of this experiment was to study the effectof MSG on the histological renal changes of mice.METHODSExperimental study using The Post Test-Only Control Group design. Thirty Swiss Webster mice with specific criteria were used as samples, divided into 3, with each 10 mice in it. The Control group (K) were given water only, while P1 and P2 groups were given gradual doses of MSG for 14 days, respectively 3 mg; 8 mg. Renal tissue further processed for the manufacture of coloring preparations histology with Hematoxylin Eosin (HE). Data were collected and further analyzed using Independent Sample t-Test and Paired Sample t-Test.RESULTSThere were renal tubule damages in the form of thickening and increasing of the averagediameter of the tubules. The statistical test showed that there were significant differences(p<0.05) between the proximal groups of K and P1; K and P2, distal groups of K and P1;K and P2, weight groups of P1; P2. There were no significant differences found betweenthe proximal groups of P1 and P2, distal groups of P1 and P2, and weight groups of K.CONCLUSIONGradual dose of Monosodium Glutamate (3 mg and 8 mg) given orally in 14 days did affect the changes of the renal structure in the form of increasing diameter of the tubule walls in Swiss Webster mice.
