Oxidative stress performs an imperative role in the onset and progression of diabetes. Metabolic enzymes and cellular organelles are detrimental to increased levels of free radicals and the subsequent reduction in anti-oxidant defence. Pyridoxamine (vitamin B6) is an indispensible nutrient for humans and is considered to be an important food additive too. The aim of this research was to examine the effect of vitamin B6 in a diabetic environment. This study reports the effects of pyridoxamine supplementation in alloxan induced diabetic rats. Diabetes was induced by the single intra peritoneal dose of alloxan (120 mg per kg body weight). Diabetic rats were treated with pyridoxamine (10 and 15 mg per kg body weight) and compared with a control set of diabetic rats without supplementation. Pyridoxamine treatment showed dose dependent recovery in all parameters. A notable decline in oxidative stress parameters and ROS production with reductions in fasting blood glucose levels along with normal patterns of the glucose tolerance test has been reported here. Histological studies reveal damage recovery in the liver as well as kidney tissues. A notable amount of recovery was observed in cellular DNA distortion and damage. It is thus advocated that pyridoxamine might help in reducing problems associated with diabetes. A probable mechanism pertaining to the action of pyridoxamine is proposed as well.
氧化应激在糖尿病的发生和发展过程中起着至关重要的作用。代谢酶和细胞器会受到自由基水平升高以及随后抗氧化防御能力下降的损害。吡哆胺(维生素B6)是人类不可或缺的营养素,也被认为是一种重要的食品添加剂。本研究的目的是考察维生素B6在糖尿病环境中的作用。本研究报告了吡哆胺补充剂对四氧嘧啶诱导的糖尿病大鼠的影响。通过单次腹腔注射四氧嘧啶(每千克体重120毫克)诱导糖尿病。给糖尿病大鼠注射吡哆胺(每千克体重10毫克和15毫克),并与未补充吡哆胺的糖尿病大鼠对照组进行比较。吡哆胺治疗在所有参数上均显示出剂量依赖性恢复。本文报道了氧化应激参数和活性氧生成显著下降,同时空腹血糖水平降低,葡萄糖耐量试验恢复正常。组织学研究显示肝脏和肾脏组织的损伤得到恢复。在细胞DNA畸变和损伤方面观察到显著的恢复。因此,有人主张吡哆胺可能有助于减少与糖尿病相关的问题。还提出了一个与吡哆胺作用相关的可能机制。
