We report a 36-year-old man with MELAS in whom a 5-month course of high-dose oral idebenone, a derivative of coenzyme Q10, increased markedly cerebral metabolic ratio of oxygen and oxygen extraction fraction without increased cerebral blood flow with PET.

我们报告了一例36岁患MELAS（线粒体脑肌病伴高乳酸血症和卒中样发作）的患者，在口服一种辅酶Q10衍生物艾地苯醌后，显著地增加了氧气和氧提取部分的比例而同时不增加患PET症的患者的脑血流量。

Simultaneously we prepared benzimidazolines with two methods by the reducton of benzimidazolium salts with NaBH_4 and Grignard addition with benzimidazolium salts. Thus we provided a new biomimic synthetic method for 9 kind of tetrahydro-β-carboline starting from carboxylic aicd and halid. A convenient synthetic method for preparing tetrahydro-β-carboline was provided.

本文以1，3-二甲基苯并咪唑碘盐和2-取代的1，3-二甲基苯并咪唑碘盐为原料，采用了NaBH_4还原和Grignard试剂加成两种方法，制备了9种1，3-二甲基苯并咪唑烷和2-取代的1，3-二甲基苯并咪唑烷作为四氢叶酸辅酶一碳单元转移新模型，在酸性条件下，以色胺作为接受一碳转移的亲核试剂，完成9种四氢-β-咔啉类化合物的新合成方法研究。

A Photolysis of 5＇-deoxyadenosylcobalamin in neutral aqueous solution and methylcobalamin in neutral and acid aqueous solution has been investigated using pulsed, time-resolved photoacoustic calorimetry in the temperature range of 10-30℃. The resultant enthalpy changes, namely CoC bond dissociation energies for the above cobalamins, 129±17, 163±21 and 176±23kJ/mol, respectively, are consistent with the values obtained by thermolytic kinetic method.

运用光声量热法研究10～30°C温度范围内辅酶〓在中性水溶液中和甲基钴胺素在酸性和中性水溶液中的光解反应，测定了其光解反应的焓变，即Co—C键离解能分别为129±17，163±21和176±23 kJ／mol，这些值和文献中用热分解动力学方法测得的值一致。

The observed enthalpy changes for above compounds, and measured cobalt-carbon bond dissociation energies, fall within the expected range of 80-180kJ/mol consistent with that from thermolytic kinetic and thermodynaminc equilibrium measurements.

值得注意的是，我们所得的〓的Co-C键离解能为176 kJ／mol，这是目前为止辅酶〓及其模型化合物中精确测定的Co—C键离解能最大值。
