The function of the addition of co-substrate ethanol was to in-situ regenerate NADH. A mathematical model was derived, in which, two substrates were catalytically reacted in sequence. The model was applied to the system involving the reduction of 2'-chloroacetophenone to R-2'-chloro-1-phenyl-ethanol by S.

深入研究了在乙醇存在下生物还原过程中酵母细胞内NADH、NAD〓、NADPH及NADP〓浓度的变化规律，发现胞内NADPH浓度迅速降低到零，而NADH浓度始终维持在较高水平，证明了用于底物还原反应的辅酶是NADH，辅助底物乙醇的加入有利于实现辅酶Ⅰ的原位再生。

In extreme cases, such as hydatidiform mole, choriocarcinoma, the body will be too high HCG levels, urine testing but not positive.

在极端的情况下，如葡萄胎、绒癌、体内HCG水平会过高，尿液检测反而不显示阳性。

In exceptional circumstances, such as hydatidiform mole, choriocarcinoma, in vivo HCG levels are too high, instead of urine testing positive for.

在非常情况下，如葡萄胎、绒癌，体内HCG水平会过高，尿液检测而不显示阳性。

Methods: 1. To detect the GC level in the serum by enzyme immunoassay kit.The serum samples were obtained from 22 psoriatic patients, 15 patients who had been clinical cured and 20 normal controls. There were standard, control, and sample wells. The standardN control and serum samples were pipeted into the appropriate wells and then the enzyme conjugate solution, GC antiserum were pipeted into each wells, incubated the wells at room temperature for 45 minutes, washed and dried each well, added TMB chromogen solution, incubated the wells for 15 minutes, added H2SO4 to stop the reaction.

1。酶免疫法测定银屑病患者治疗前、后血清GC水平的变化：血清标本来自22例治疗前银屑病患者、15例临床治愈的银屑病患者第四军匝大学硕＿］，学位论文和 20名正常人对照，设置标准品孔、对照品孔和样本孔，标准品、对照品和血清样品分别加入对应各孔中，在各孔中再加入酶联GC，兔抗GC血清，室温下放置 45分钟后清洗吸干，加 TMP色原，15分钟后 11p。

"Now that we know high levels of insulin are associated with altered intestinal chylomicron metabolism and a build up of these particles in the blood vessel walls, our next step is to use this animal model to look closer at the cellular mechanisms and try to figure out how this happens," said Dr. Donna Vine, a nutritional scientist at the U of A and co-author of the paper.

"现在我们已经知道了高水平的胰岛素相关变造肠道chylomicron代谢，并建立这些粒子在血管壁，我们的下一步就是要利用这种动物模型，以寻找更接近在细胞机制，并试图分析出如何出现这种情况，医生说："唐娜畏缩不前，营养科学家，在美国的一个合作本文的作者之一。
