In this study, we isolate, purify and characterize endo-β-glucanase by Ascomycete Xylaria regalis. The cellulose-containing medium is used to induce the production of the cellulose-degrading enzymes. When these enzymes are produced at maximum level, we harvest and filtrate the culture medium. The filtrate is purified by anion exchanger column and hydrophobic interaction column (phenyl-650M). The purification fold of endo-β- glucanase increases 4.3 times, the specific activity approaches 3.7 unit/mg, and the recovery is 27.6%, respectively.

为了分离且纯化此株菌产生在培养基中的endo-β-glucanase，先将此菌在cellulose液态培养基中大量培养，在此酵素达到最高峰时，利用滤纸过滤将菌丝及菌液分开，收集粗酵素液，再经过阴离子交换树脂及疏水性层析管柱(Phenyl-650M)等步骤予以纯化，所得到最终酵素纯度为 4.3倍，比活性为3.7 unit/mg，回收率为27.6%。

In clinical. acetylcholinesterase inhibitors reduce the breakdown of synaptic acetylcholine, have been modestly effective in improving the cognitive deficits of Alzheimer's disease.The goal of this work is to determine enzyme kinetics and mechanisms of acetylcholinesterase and butyrlcholinesterase inhibition by five cardiovascular drugs, lovastatin, simvastatin, amlodipine besylate, nifedipine, and hydralazine hydrochloride, and two benzodiazepines, diazepam and chlordiazepoxide hydrochloride. All drugs in this study are reversible mixed-type inhibitors of acetylcholinesterase and butyrylcholinesterase. The pKi values for acetylcholinesterase and butyrylcholinesterase inhibition by the cardiovascular drugs are linearly correlated with the molecular weights of the drugs with the slopes of 0.005 and 0.0021, respectively. Therefore, van der Waals' interactions between acetylcholinesterase and the cardiovascular drugs are stronger than those between butyrylcholinesterase and the drugs. This is probably due to a smaller active site gorge and a more significant peripheral anionic substrate binding site of acetylcholinesterase than those of butyrylcholinesterase.

本研究之目的系决定乙醯胆碱酯酵素和丁醯胆碱酯酵素被五种心脏血管药物lovastatin， simvastatin， amlodipine besylate， nifedipine、hydralazine hydrochloride和两种benzodiazepines：diazepam和Chlordiazepoxide hydrochloride的抑制作用之动力学及机转，这些药物都是乙醯胆碱酯酵素和丁醯胆碱酯酵素的可逆性、混合型之抑制剂，实验结果显示，五种心血管药物对於乙醯胆碱酯酵素及丁醯胆碱酯酵素抑制之pKi值和药物之分子量呈直线之关系，斜率分别为0.005及0.0021因此丁醯胆碱酯酵素，与心血管药物间之凡德瓦作用（van der Waals' ）比乙醯胆碱酯酵素与心血管药物间者弱，这可能原因是丁醯胆碱酯酵素之活性区域比乙醯胆碱酯酵素之活性区域更宽广，但丁醯胆碱酯酵素之周边阴离子区域不及乙醯胆碱酯酵素之周边阴离子区域者明显重要，由於五种心血管药物对於乙醯胆碱酯酵素和丁醯胆碱酯酵素抑制之pKi值存在著线性关系表示此种抑制作用系经过共同之反应机理。

Bamboo mosaic virus encodes a 155-kDa replicase that the middle region contains a helicase-like domain according to the existence of several conserved featured motifs of helicase. Previous studies showed that the helicase-like domain exhibits both ATPase and RNA 5'-triphosphotase activities, and Mg2+ is essential for both activities. Mutagenesis of conserved motifs showed these amino acids play important roles for enzymatic activities. These results suggested that the properties of this denatured and renatured protein are coincident with other SF1 helicases.

In this study, we investigate the heat-induced inhibition of drug-metabolizing enzyme activity in mice fed with freeze-dried, heated freeze-dried or half amount autolyzed freeze-dried Brussels sprouts powder. 0.5% ethoxyquin diet was fed to another group of mice as a positive control. The study mice, four per group, were fed a diet consisting of 20% Brussels sprouts for 7 days. Each group had its own pair-fed group. We found significantly greater inductions of glutathione S- transferase, quinine reductase, and phase Ⅱ drug-metabolizing enzyme activities in groups fed within freeze-dried and heated freeze-dried Brussels sprouts than their pair-fed groups. These findings indicate that intestinal microflora still can hydrolyze glucosinolates without plant myrosinase activity, though the alteration of cytochrome- P-450 1A (CYP1A, a phase Ⅰ drug-metabolizing enzyme) induction was only 1.4-fold.

本实验欲进一步探討加热处理之抱子甘蓝对phase Ⅰ与phase Ⅱ解毒酵素活性之影响差异，实验分三组，抱子甘蓝(1)冷冻乾燥组（glucosinolate未裂解）(2)加热冷冻乾燥组(3)半量之裂解冷冻乾燥组（glucosinolate已裂解），(4)and 0.5% ethoxyquin diet was used as a positive control以2%重量混合成饲料，餵以小白鼠（4只／组）7天，结果发现，在第(2)组小白鼠GST phase Ⅱ酵素）活性显著上升，显示在植物裂解酵素不存在之状况下，肠胃道之微生物仍可促进裂解反应，但由CYP1A活性增加不显著（仅1.4倍）看来，根据定义：单独phase Ⅱ酵素活性增加，为monofunctional induction/inducer，可加速致癌物之代谢。

Cinnamomea, antrocamphin A was purified from previous ethanol extraction using bioactivity-guided fractionation. As results, the antrocamphin A could significantly inhibit NO and PGE2 autacoids production in LPS-induced RAW 264.7 macrophage cells. Meanwhile, the mRNA and protein expression levels of iNOS and COX-2 were inhibited by antrocamphin A in a dose-dependent manner. Antrocamphin A also reduced the translocation of NF-κB induced by LPS, which was associated with the prevention of the degradation of I-κB, and subsequently decreased p65/p50 proteins level in the nucleus. This is the first report demostrating the A.
