2,6-二甲基-3,5-二氯-4-吡啶醇的合成及其抗球虫作用的研究

以双乙烯酮为原料,经二聚合反应,得脱氢醋酸。再由脱氢醋酸分别经水解、氨化、氯化反应(总收率26.97%)或高压氨化、氯化反应(总收率39.52%)制得文题化合物(m.p.345℃)。药理试验表明其毒性较低(LD_(50)>10g/kg)。用作饲料添加剂可明显提高鸡的增重率,降低死亡率,防治球虫病。     

电阻抗法在细菌耐药性试验中的应用

将电阻抗法应用于医学临床细菌耐药性试验。笔者用自制的微生物电阻抗传感器和电阻抗测量装量,通过测量接种细菌的培养基电阻抗值(V值),并将细菌在培养期间内取得的所有V值描记成“阻抗曲线图谱”,因细菌培养基所产生的阻抗曲线图谱与在细菌培养基中滴加了抗菌药物所形成的阻抗曲线图谱形态有明显差别,利用这种曲线形态的差别尝试用来判断细菌的耐药性、该研究对实现医学临床快速耐药性试验,药敏检测自动化、智能化有一定的实际意义．     

Principle, traits and functions of electrochemical fingerprint of Chinese traditional medicine

In regard to such challenging analysis problems as scientific identification and quality evaluation of Chinese traditional medicine, the electrochemical fingerprint technique of Chinese traditional medi- cine has been researched. The principle, traits, functions, etc., of the electrochemical fingerprint have detailedly been analyzed and discussed by the B-Z oscillatory system using malonic acid as main dissipation substance, characterized by the fact that different influences of different Chinese traditional medicines on the mechanism of the oscillatory reaction cause different changes of the shape of the potential-time curve of the oscillatory system under the conditions of constant tem- perature and pressure. An economical, simple and convenient, easy pushing and effective scientific method for distinguishing and evaluating multifarious Chinese traditional medicines has success- fully been put forward.     

阿奇霉素在鸡组织中的消除规律及临床毒性研究

探讨了阿奇霉素对仔鸡的临床毒性及其在鸡组织中的消除规律.阿奇霉素以0、50、100和200 mg/L的水溶液供麻花肉鸡连续自由饮用14 d后,测定血清生化指标、脏器系数,并进行组织病理学观察;同时,阿奇霉素按10 mg/kg的剂量连续对肉鸡灌服7 d后测定体内各组织中的残留量.结果显示,高剂量组肉鸡的肝脏系数和谷丙转氨酶活性存在显著差异(P<0.05),阿奇霉素在肉鸡肝脏中的残留时间最长,其他依次是肾脏、脾脏、肌肉和血清.表明肉鸡的肝脏为阿奇霉素的中毒靶器官;根据其在鸡组织中的消除规律,阿奇霉素的肉鸡休药期可定为15 d.

Determining method and conditional factors of electrochemical fingerprint of Chinese traditional medicine

The thermodynamic systems and kinetic model suitable for the electrochemical token of the compo-nent throng in Chinese traditional medicines have been analyzed. It has been indicated that the damp oscillatory reactions in the non-equilibrium close system and open system without the supplement of dissipative substance have important significance for the throng token and analysis of chemical com-ponents in Chinese traditional medicines. Various factors influencing the electrochemical fingerprint,such as reactant species and their concentrations,electrode types,temperature,stir rate,the kind,dosage and granularity of Chinese traditional medicines,have amply been researched by the B-Z os-cillatory reaction which used malonic acid as a main dissipative substance. In addition,the quantitative information about the chemical components in Chinese traditional medicines has been discussed in detail. The method and its conditions for determining the electrochemical fingerprint used in scientifi-cally distinguishing and evaluating Chinese traditional medicines have successfully been put forward.
