Abstract

The present study has attempt to analyze the changes in the biochemical and mineral contents of aluminum intoxicated bone and determine the protective action of desferrioxamine (DFO) and deferiprone (DFP) by using Fourier transform infrared (FTIR) spectroscopy, X-ray diffraction (XRD), inductively coupled plasma optical emission spectroscopy (ICP-OES), and scanning electron microscopy (SEM) techniques for four groups of animals such as control (Group I), aluminum intoxicated (Group II), Al+DFP (Group III) and Al+DFO+DFP (Group IV) treated groups respectively. The FTIR spectra of the aluminum intoxicated bone showed significant alteration in the biochemical constituents. The bands ratio at I1400/I877 significantly decreased from control to aluminum, but enhanced it by Al+DFP to Al+DFO+DFP treated bone tissue for treatments of 16 weeks. This result suggests that DFO and DFP are the carbonate inhibitor, recovered from chronic growth of bone diseases and pathologies. The alteration of proteins profile indicated by Amide I and Amide II, where peak area values decreased from control to aluminum respectively, but enhanced by treated with DFP (p.o.) and DFO+DFP (i.p.) respectively. The XRD analysis showed a decrease in crystallinity due to aluminum toxicity. Further, the Ca, Mg, and P contents of the aluminum exposed bone were less than those of the control group, and enhanced by treatments with DFO and DFP. The concentrations of trace elements were found by ICP-OES. Therefore, present study suggests that due to aluminum toxicity severe loss of bone minerals, decrease in the biochemical constituents and changes in the surface morphology.

摘要

本研究试图通过傅里叶变换红外光谱(FTIR)、X射线衍射(XRD)、电感耦合等离子体发射光谱(ICP-OES)和扫描电子显微镜(SEM)技术,分析铝中毒骨骼的生化和矿物质含量变化,并确定去铁胺(DFO)和去铁酮(DFP)对四组动物(分别为对照组(I组)、铝中毒组(II组)、铝+DFP组(III组)和铝+DFO+DFP组(IV组))的保护作用。铝中毒骨骼的FTIR光谱显示生化成分有显著改变。在16周的治疗中,从对照组到铝中毒组,I1400/I877处的谱带比值显著降低,但在铝+DFP组到铝+DFO+DFP组处理的骨组织中该比值升高。这一结果表明,DFO和DFP是碳酸盐抑制剂,可从骨骼疾病和病理的慢性发展中恢复。由酰胺I和酰胺II表示的蛋白质谱发生改变,其中峰面积值从对照组到铝中毒组分别降低,但分别经DFP(口服)和DFO+DFP(腹腔注射)处理后升高。XRD分析表明,铝毒性导致结晶度降低。此外,铝暴露骨骼中的钙、镁和磷含量低于对照组,而经DFO和DFP处理后含量增加。通过ICP-OES测定微量元素浓度。因此,本研究表明,铝毒性导致骨矿物质严重流失、生化成分减少以及表面形态改变。
