Starting from 3-benzoyl-5-formyl-indolizine, 3-benzoyl-5-(2'2'-diacetylethenyl)-indolizines and analogs were obtained by the 〓mediated aldol condensation or Wittig reaction. These compounds,promoted by low-valent titanium, gave highly functionlizedcycl[3,2,2]azine derivatives. The coupling reaction proceeded betweenthe carbonyl group and the carbon-carbon double bond, a rare example inMcMurry reaction.

我们以3-苯甲酰基-5-甲酰基中氮茚为原料，通过三碘化钐促进的aldol反应和Wittig反应制备了3-羰基-5-羰基乙烯基中氮茚，随后经低价钛还原偶联，没有生成正常的分子内羰基-羰基偶联产物，而是得到反常的羰基与α，β-不饱羰基的双键偶联产物，较高收率地得到了含多官能团的CycI[3，2，2]azine衍生物。

Methods: Separated 120 cases with glomerular diseases into chronic glomerular nephritis group (70 cases, including 33 cases with normal serum creatinine, 17 cases with azotemia, 20 cases with uremia, 33 cases accompanied with hypertension), acute nephritis group (12 cases), nephritic syndrome group (38 cases), and selected 30 healthy cases as control group. Detected concentration of NO in serum with nitrate reductase method, and made comparison among groups.

120例肾小球疾病患者分为慢性肾小球肾炎组（70例，其中血清肌酐正常33例，氮质血症17例，尿毒症20例，伴有高血压33例）、急性肾炎组（12例）、肾病综合征组（38例），同期选择30例健康体检者作为对照组，采用稍酸还原酶法测定肾小球疾病患者及对照组血浆NO浓度，并对各组NO浓度进行比较。

H2-uptake phenomenon of the bacterial ferritin is still found in an analogy system of micro-oxygen environment of entire cell Azotobacter vinelandii in vitro, which indicates that the H2-uptake reaction can be carried out by the ferritin within the cell.

此外，细菌铁蛋白在体外模拟棕色固氮菌整体细胞内的微量氧环境体系中仍有氢还原现象，因而推测细菌铁蛋白在该菌体内也能进行吸氢反应。

In order to select high nitrogen-fixing azotobacter strains, nitrogenase activity of 13 strains separated in the rhizosphere in Gansu non-leguminous crop fields were measured by acetylene reduction method. Also the fertilization effect of the strains on spring wheat was investigated via pot experiment.

为挑选具有高固氮能力的自生固氮菌菌株，用乙炔还原法对甘肃省春小麦和玉米等非豆科作物根际土壤中分离所得的13株菌进行固氮酶活性测定，并通过盆栽试验对其进行春小麦肥效试验。
