| ABSTRACT In this study, we determined the amount of carnosine and anserine in water buffalo meat without hanging treatment and the free amino acid profile by using amino acid analyser with post-column ninhydrin derivatization procedure. The main free amino acids present in samples were glutamic acid (>60 mg/100 g), followed by alanine, glycine, and arginine. Other protein amino acids were detected in minor amounts (less than 2 mg/100 g). Among the non-protein amine-containing compounds, taurine and urea were the most abundant. The analysis showed that 50% of the total free amino acids was represented by dipeptides carnosine (average ~130.3 mg/100 g) and anserine (average ~17.9 mg/100 g). Thus, this study for the first time reports the free amino acids... |

| ABSTRACTThe aim of this work was to investigate whether the free radical scavengers, L-arginine (L-arg) and/or carnosine, either alone, or in combination would modulate tissue injury induced by hypoxia by measuring Fischer's ratio [concentrations of branched chain amino acids (BCAAs)/aromatic amino acids]. Decreased Fischer's ratios and increased malondialdehyde (MDA) led to pathogeneses of many diseases. Rats were injected with sodium nitrite (60 mg/kg) to establish hypoxia. They were treated with L-arg, (200 mg/ kg) and/or carnosine (200 mg/ kg) and their combination 24 and 1 h prior to sodium nitrite intoxication. The results revealed that hypoxia significantly decreased hemoglobin, arginine, citrulline and proline and increased sLDH, MDA , ammonia ,... |
