The invention relates to a method for treating gaseous VOCs by a solid extraction-electro-catalytic oxidation method and a device thereof. The method has the steps that: firstly, an electromagnetic type air compressor is used for controlling the gas flowing velocity by a glass rotameter so as to ensure contaminations in the contamination solution in a gas washing bottle to be stripped into an electrochemical reactor; secondly, microporous aeration heads are distributed in the electrochemical reactor, after being stripped into the electrochemical reactor, the gas is distributed in the electrochemical reactor by the microporous aeration heads, takes parts in the electrochemical reaction and passes through the cathode of absorptive and conductive porous material and the anode of iron sheet in sequence; thirdly, the treated gas finally flows out from the top end of the electrochemical reactor and enters into the gas absorption solution.

本发明涉及一种固态萃取-电催化氧化法处理气态VOCs的方法及装置，方法步骤：第一步，电磁式空压机通过玻璃转子流量计控制气体流速，将气体洗瓶中的污染物溶液中的污染物吹脱进电化学反应器；第二步：电化学反应器中布有微孔曝气头，气体吹脱进入电化学反应器后，通过微孔曝气头分布于电化学反应器内，参加电化学反应，依次经过通过吸附性导电多孔材料阴极和Fe片阳极；第三步，经处理后的气体最后从电化学反应器顶端流出进入气体吸收溶液。

Safrole is the major component of PBI. Safrole is known to be genetic toxicity and carcinogenesis, and forms safrole-DNA adducts.

文献指出，槟榔萃取物会活化NF-kB讯息传递路径，但是黄樟素和NF-kB之间的关系及其讯息传递路径的机转仍不明了。

However, the molecular evidence of areca in oral tumorigenesis is still not clear. In this study, the NF-kB activity in oral cells after ANE or safrole treatment was examined.

然而目前槟榔参与口腔癌化过程之分子证据仍未明了，因此本研究即是针对槟榔子水萃取液与黄樟素对於口腔上皮中NF-kB活性之调控做一探讨。

Areca nut extract exerts cytotoxicity and genotoxicity to several types of cells. In every gram of Piper betel inflorescence contains a high concentration of 15.4 mg safrole. As a result, chewing BQ containing Piper betel inflorescence may result in high safrole (420 μM in saliva during chewing) exposure.

已知槟榔子水萃取液对多种型态细胞具有细胞毒性以及基因毒性；而每公克荖花中含有约15.4 mg黄樟素，因此在嚼食荖花槟榔块过程中，口腔将暴露於大量黄樟素中（唾液中可测得黄樟素浓度为420 μM）。

Notably, a low dose of D. salina extract was sufficient to aggravate As2O3-induced cytotoxicity in HL-60 cells.

值得注意的是，低剂量杜莎藻萃取物的处理便足以促进三氧化二砷的毒杀作用。

They include the variation of the degradement velocity of different sample, the inhibition product of PCR, the amount of DNA extraction, quality of DNA and the heteroplasmy of some tissue. Correct sequencing, comparison of the result of forward and reverse primers sequencing should be done to rule out wrong signals, and prevent contamination. In addition to gene sequencing, low grade heteroplasmy could be dealt by Denaturing high performance liquid chromatography. Multiplex Ligation-dependent Probe Amplification. The analysis of mitochondrial HV Ⅰ, HV Ⅱ sequencing is able to identify the maternal sanguinity, then it could assist in the human identification. It also complements the genomic STR system in distribution of population, the origin of human, and analysis for fossil.

分析粒线体DNA时必须考虑各类检体腐败DNA降解速度之不同、PCR的抑制物质、DNA的萃取量及品质、特定组织的异质现象、萤光序列分析图及正、反向引子定序结果比对、排除杂讯干扰、防治污染等，除以基因定序外，低程度的异质现象也可用Denaturing high performance liquid chromatography、Multiplex Ligation-dependent Probe Amplification等方法分析，粒线体HV Ⅰ、HV Ⅱ碱基序列的分析可鉴别一个人的母系血缘关系、辅助人类身分鉴定，对於族群分布、人类起源探讨、远古检体的分析可作为辅助STR系统的利器。
