Lthough August Weismann had expressed doubts about the theory earlier, it did not fall out of scientific favor until the 1890s, when a series of experiments by James Cossar Ewart in Scotland and other researchers in Germany and Brazil failed to find any evidence of the phenomenon. The result obtained by Morton could probably be caused by the display in the offspring of the recessive genes inherited by the Morton's mare from her parents or grandparents

ugust Weismann对理论表示怀疑(也就是你回应提到马交配的实验，在本段的上半部有提及我就不引用了)但这理论始终得到学界支持，直到James Cossar Ewart在苏格兰，德国，巴西所做的系列实验都无法发现有关现象的根据；Morton观察到的，可以说是马遗传了亲代或祖父母的隐性基因，并表现出性状也就是最初实验马交配发表先父遗传的人

They can be classificated to two kinds. One kind is build by photomultiplier; another kind is build by MCP. The mechanism of delayed luminescence is discussed with subradiation. A photon count system is built. To proof the biophoton is a kind of ultra weak photon stream originate from exothermic reaction, and primarily discuss the relationship between the delayed luminescence and proteins activity, we chose microphyllous banyan leave , ficus elastica leave, gingkgo leave, Chinese fan palm leave, and cinnamomum camphora leave as biological samples. The ultra weak photon emission from normal biosamples, and proteins inactivated biosample were measured separately with photon count system. The results showed that the delayed luminescence of biosamples have

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。
