The thermodynamic investigation of adsorptions shows that adsorption of CCTS to Pb~(2+),Cu~(2+),Cd~(2+),Ni~(2+) is spontaneous.Because the values of Gibbs free energy are negative and the calculated entropy values of interactions are positive.However the positive values of the variation in enthalpy show that besides chemisorption, other processes of decalescence, such as physical adsorption and swelling of CCTS were also involved.

CCTS对各重金属离子的吸附热力学分析结果表明：CCTS对各重金属离子吸附熵变△adsS为正值，并且吸附自由能改变量△adsG均为负值，说明CCTS对各重金属离子的吸附是自发进行的，但其吸附焓变△adsH为正值，说明CCTS对重金属离子的吸附不仅仅是化学吸附的过程，还伴随着其他如物理吸附、吸附剂溶胀等吸热过程。

According to experimental results and etiopathogenisis and pathology of osteoporosis , and analyzing review investigation on hepcidin、associations of bone metabolism and iron metabolism and relations of ferri ion and calcium ion,we can make conclusions as follows: 1、We applied single manmade intervention approach to induce osteoporosis model in this study, there was no other influential factor. In the termination of test , rats bone density and bone histological anatomy indicated that osteoporosis model was creditable,meanwhile hepatic functional enzyme and hepatic microtome section demonstrated that hepatic function had noci-influence induced by medicinal herbs resource. Accordingly, we could believe that hepatic hepcidin gene expression and serum hepcidin contents can represent internal iron metabolism changes at selected test time. 2、In this investigation, different findings between test group and control group indicated that:according to changes of hepcidin gene expression measured by RT-PCR and changes of serum hepcidin contents determined by ELISA kit , there were correlations between hepcidin and rat osteoporosis model induced by retinoic acid. 3、Under the condition of this investigation,there was a interactive hypothesis as follows: Hepcidin iron metabolism←→ferriion←→calcium ion←→osteoporosis.

根据本次实验结果，对骨质疏松的病因病理的认识及铁代谢与铁调素、骨代谢与铁代谢关系、铁离子与钙离子的关系系列研究的回顾，经分析得出如下结论：1、本研究骨质疏松模型采用单一人工干预方法，没有其他影响因素；实验结束时大鼠骨密度、骨组织学检查表明骨质疏松形成，同时肝脏功能酶和HE切片显示肝脏功能未受药源性产生明显损伤性影响；因此，同期不同时间组大鼠肝脏铁调素基因表达、血清铁调素含量可以代表体内铁代谢不同时间的变化。2、在本研究中，模型组与对照组研究结果的差异表明：铁调素基因RT-PCR变化、血清铁调素ELISA测定含量变化与维甲酸制作的大鼠骨质疏松模型形成有实验相关性。3、在本研究平台下，形成了一个互相影响的假设图：铁调素←→铁代谢←→铁离子←→钙离子骨质疏松。
