This paper reports that the micro amount of guanine and adenine in DNA can be determined simultaneously by anodic differential pulse voltam-metric method and so a rapid determination of G + C/A + T value of DNA is established. The sensitivity of this method is about 100 times higher than the ultra-violet adsorption method, in which the purines are seperated by paper chromotography. The time required for once determination is only11/2hr.We use the DNA of calfthmos as the standard sample in the experiment and...

This paper reports that the micro amount of guanine and adenine in DNA can be determined simultaneously by anodic differential pulse voltam-metric method and so a rapid determination of G + C/A + T value of DNA is established. The sensitivity of this method is about 100 times higher than the ultra-violet adsorption method, in which the purines are seperated by paper chromotography. The time required for once determination is only11/2hr.We use the DNA of calfthmos as the standard sample in the experiment and the result shows that this method is accurate. The G + C/A + T values of six sorts of DNA of E. coli, heliothis armigera and so on are determined.

本文采用阳极差分脉冲伏安法同时测定微量DNA水解碱基鸟嘌呤和腺嘌呤的含量,从而建立了一种能对微量DNA进行快速测定G+C/A+T值的方法。本方法比层析分离后紫外吸收法灵敏度约高二个数量级,测定时间缩短到一小时半左右。经用德国小牛胸腺标准DNA进行实验,证明本方法准确可靠;并测定了大肠杆菌、棉铃虫等六种DNA的G+C/A+T值。

Ethyl-(±)-cis,trans-2,2-dimethyl-3-(2′,2′-dichlorovinyl)-cyclopropanecarho xylate was dehydrochlorinated with sodium ethyoxide, followed by saponification and acidification to give corresponding chloroethynyl acid.Its sodium salt was csterifred respectively with 4-methoxymethyl benzyl-triethyl ammonium chloride and 3-phenox-ybenzyl-triethyl ammonium chloride to give corresponding esters.The former synthetic pyrethrod showed higher insecticidal activity against houseflies, 4th instar mosquitoe larva and German...

消旋-顺,反2,2-二甲基-3-(2',2'-二氯乙烯基)-环丙烷羧酸乙酯用乙醇钠醇溶液处理脱去一分子氯化氢生成的消旋-顺,反-2,2-二甲基-3-(2'-氯乙炔基)-环丙烷羧酸乙酯,再经皂化、酸化制得相应的羧酸.后者的钠盐分别和氯化对甲氧甲基苄基三乙铵及氯化3-苯氧基苄基三乙铵进行酯化制成一氯甲苄菊酯及一氯菊苯醚酯(Ⅵ及Ⅶ).通过对家蝇成虫、淡色库蚊四龄孑??及雄性德国小蠊的药效比较,前一种新合成拟除虫菊酯比后者为优越.

The technological improvement in the preparation of Blattaria chromosomal sepecimens is reported briefly. The chromosomal Karotype of Blattela germanica in Changsha area was described. The Karotype of Blattela germanica was 2n=24 for female, 2n = 23 for mate. It is consistent with the observation reported abroad.

作者改进了染色体标本制作方法,对长沙地区德国小蠊的染色体核型进行了研究。染色体散开满意,核型清楚。德国小蠊的染色休核型雌2n=24;雄2n=23。
