Protective Effects of Methionine on some Physiological and Biochemical Parameters of Triton-Stressed Male Rats

The aim of this study is to find out the effect amino acid methionine 35 mg/kg feed with diet minimize harms caused by oxidative stress resulting from treatment Triton at a dose (300 ml/kg) on physiological and biochemical parameters. This was conducted Technical Institute/Mosul for period 1/12/2021 - 1/2/2022 protective effects some parameters Triton-stressed white male laboratory rats, as their weight ranged 180-220 g ages between 12- 14 weeks. After confirming that they are free diseases, help veterinarian. Some were measured, namely, glucose, cholesterol T.C., triglycerides T.G, (LDL-c) low-density lipoprotein cholesterol, (VLDL-c) very (HDL-c) high-density atherogenic index. In study, used 24 distributed randomly into four groups 6 rats/group. And it follows: Control group: injected 1 ml distilled water equalize holding rats. They 300 ml/kg body Triton. Methionine given (35 diet) triton weight) concentration. Dosing process took place daily (8) weeks.The showed significant decrease probability value (P≤0.05) in concentration each triglycerides, LDL-c, VLDL-c, index, however, HDL-c levels found be higher group compared control group. Treatment also led an improvement rats subjected stress. Keywords: methionine, triton, lipoproteins,
