Monosodium Glutamate Plus Artemether-lumefantrine Overdose Altered Malondialdehyde, Total Protein and Albumin Concentration in Rats

Abstract

This study aimed at assessing alterations in malondialdehyde, MDA, total protein and albumin concentration in the serum and liver homogenate of monosodium glutamate (MSG)-challenged rats co-treated with artemether-lumefantrine, AL. Methods involving colourimetric estimation were employed in thirty rats randomly grouped into six (n = 5) and for seven consecutive days, fed feed and water (Group A), AL therapeutic dose (Group B), AL overdose (therapeutic dose × 5) (Group C), MSG (8000 mg/kg body weight) (Group D), AL therapeutic dose plus MSG (Group E) or AL overdose plus MSG (Group F). Total protein concentration (2.64±0.09 g/dL, 2.81±0.14g/dL, respectively) in the liver homogenate of rats exposed to MSG (group D) or MSG plus AL overdose (group F) and malondialdehyde concentration in the liver homogenate of MSG plus AL overdose-fed rats (0.45±0.04 mg/ml) lowered (P<0.05) as against other groups. However, serum albumin concentration in MSG (2.59±0.13 g/dl) or AL overdose plus MSG (3.24±0.12 g/dl) fed rats was higher (P<0.05) compared to the control (2.02±0.04 g/dl). The Total protein: Albumin ratio lowered while the Albumin: total protein ratio increased in rats in MSG, AL overdose plus MSG or AL overdose groups compared with the control. Thus, the apparent MSG plus AL overdose-induced adverse influence on the studied parameters and samples of non-malarial infested rats could be via compromised liver-mediated protein metabolism capacity and bio-functions following possibly enhanced protein-malondialdehyde adduct formation in the rats.

Effect of Amlodipine on Monosodium Glutamate-Induced Cardiac Oxidative Stress in Rats

“…and co-assessed by the metabolic content of Zn, Mg, ALB and TP [18]. Decrease in TP and ALB content indicated increased generation of free radicals that promote induction of oxidative stress[34] while decrease in Zn and Mg content indicated down-regulation in the activity of antioxidant enzyme, SOD and consequent increase in oxidative stress[18]. The response on these co-regulators of oxidative stress followingexposure to MSG concertedly pointed to induction of oxidative stress in the rats' heart tissue.…”
