The results indicated that the pesticide could be distributed through the body and cumulated in peripheral compartment relatively,but it could be eliminated rapidly.With parameters such as t1/2α valued 3.40min,t1/2β 59.03min and Cl 0.018ml·min-1,Its metabolism followed two-compartment open model after administration of 10 mg/kg.It was primary distributed to blood-riched organs and fat tissues and ready to be biotransformed.The metabolic product were detected in choler,which had stronger polarity with retention time 4.25min;and no parent compound was found in both urine and faeces.Key words: Toxicokinetics;Fenamithion;Organophosphorus pesticide

结果显示：螨胺磷在体内全身分布，并有周室富集，消除较快，在10mg/kg静脉注射呈二室模型，t1/2α为3.40min，t1／2β为59.03min，全身清除率Cl0.018ml·min-1；螨胺磷主要分布于血流量大的器官及脂肪组织；螨胺磷在体内不稳定，能被肝脏代谢转化成极性更高的化合物后经由胆汁排出，该成分可在同样的色谱条件下被分离，峰保留时间4.25min；粪尿中均未检出原药。

Because Fov also existed in the roots ofsymptomless seedlings and the stems of both symptomatic and symptomless seedlings afterinoculation,the induced SOD isozyne seems to be originated from plant,not Fov.

由于在接种但未显症的棉株根中和显症或不显症棉株的茎中均可高频率地分离到Fov，因而初步判断该诱导性SOD酶源于棉花基因组中的某一SOD酶基因被活化。

从采自甘肃漳县的刺苞蓟全草的甲醇提取物中，采用同样方法分离纯化得到10个化合物，鉴定了其中7个化合物的结构，未发现新化合物。

The hydrogenation and methyl esterification of furoic acid over Pd-Ni/γ-Al2O3 catalysts was investigated in fixed bed micro-reactor under different conditions such as reaction temperature,pressure,H2 space velocity,space velocity of furoic acid and methol,ratio of H2 and furoic acid and so on.

以糠酸、甲醇、氢气为原料，采用连续流动固定床微反应器，Pd-Ni/γ-Al2O3为催化剂，使糠酸一步加氢甲酯化生成α-四氢糠酸甲酯。研究了反应的温度，压力，气、液体流速，进料流量等因素对催化反应的影响。结果表明：在1.5MPa，250℃，氢气空速3300 h-1，液体空速3.0 h-1(氢油比为50)时，糠酸转化率为96.6%，四氢糠酸甲酯的选择性97.2.0%，产率94.0%。催化剂稳定性较好，连续运转280小时后未见活性下降。该反应体系活性高，选择性好，反应压力低，催化剂性能稳定，操作简单，产物易分离

Immunorelated pancytopenia or hemocytopenia is a kind of disease with a relative clear pathological mechanism which was separated from bone marrow failure disease.It was thought to be caused by unbalance of T lymphocyte regulation and abnormal of B lymphocyte mount,subgroup,and function,which result in production of autoantibodies destroying or suppressing the inmature bone marrow hematopoietic cell and peripheral hypocytosis.

免疫相关性全血细胞减少或血细胞减少症是从骨髓衰竭性疾病中分离出的一种病理机制相对清晰的独立疾病体系，是由于T淋巴细胞调控失衡导致B淋巴细胞数量、亚群、功能异常，进而产生抗骨髓未成熟造血细胞自身抗体并破坏或抑制之，最终导致外周血细胞减少的一类疾病。

Avicennin A, a new isocoumarin , was isolated from ethyl acetate extract of the mangrove endophytic fungus No.

2533号菌是从南海红树avicennia嫩叶获得的一种内生真菌，其代谢产物很丰富，从它的培养液中分离出很多有意义的化合物，其中异香豆素avicennin－A是新化合物，未见文献报道。

Methods: Under peridural anesthesia, the right rectus incision was adopted. First, the vessels in lesser curvative of stomach was amputated and ligated. Second, splenic artery was ligated to deflate spleen .Then ,splenic artery and renal vein were amputated and side-to-side anastanosised with each other. Result: Of the 36 cases,the portal free pressure decreased by different degree in 23 cases, unchanged in 10,and increased in 3 postoperatively. The follow-up ranged from 1 to 5 years.

在硬膜外麻醉下经右腹肌切口进腹、采用先作胃小弯的血管彻底离断，再结扎脾动脉、使脾脏缩小后，而后分离出脾静脉和肾静脉进行端侧吻合，结果：36例中23例病人吻合后测得门脉自由压均较分流前有不同程度的降低，10例门脉自由压未变化。3例高于分流前压力。
