(1) After oral administration of 5 mg/kg of HCT to normal intact saline-loaded rats, a significant increase in K~+ excretion in urine was observed only in three out of seven experiments, and in the other four, a tendency of increase could still be noticed, though the changes were statistically non-significant. On the other hand, the same dose of HCT orally administered to adrenalectomized rats, both waterloaded and saline-loaded, did not cause any increase in K~+ excretion in all experiments. However, when a...

(1) After oral administration of 5 mg/kg of HCT to normal intact saline-loaded rats, a significant increase in K~+ excretion in urine was observed only in three out of seven experiments, and in the other four, a tendency of increase could still be noticed, though the changes were statistically non-significant. On the other hand, the same dose of HCT orally administered to adrenalectomized rats, both waterloaded and saline-loaded, did not cause any increase in K~+ excretion in all experiments. However, when a sodium retaining steroid, DOCA, was given in addition to HCT, a significant increase was invariably noticed. This, therefore, may serve as an experimental evidence in direct support of Edmonds' hypothesis, derived from his clinical observations, that aldosterone might play an important role in the Na~+-K~+ exchange in question. (2) Acotazolamide, a potent carbonic anhydrase inhibitor, was found to retain partially its effect of increasing K~+ excretion in adrenalectomized rats, and this was potentiated by the combined use of DOCA. From these results it is evident that the cessation of Na~+-H~+ exchange by carbonic anhydrase inhibition and the level of aldosterone are the two independent conditions essential for the Na~+-K~+ exchange in question. When they are combined, the effect is apparently potentiated. (3) An aldosterone antagonist 7-thioacotyl spirolactone was shown to be capable of antagonizing the effect of DOCA on the K~+ excretion, but without any action on that of acotazolamide. This gives further evidence for the specificity of its aldosterone antagonistic action, and it also supports the view that acotazolamide acts independently.

(一)正常大白鼠盐水負荷时,口服5毫克/公斤HCT,在7次实驗中,有3次实驗表現显著排鉀增多,而另外4次則虽也均有排鉀增高傾向,但統計测驗不显著。推測和各批正常员体內醛固酮水平高低有关。 (二)去腎上腺大白鼠,无論水負荷或盐水負荷,口服5毫克/公斤HCT,在6次实驗中均不能增加鉀排泄,但預先肌肉注射DOCA后,就轉为明显,从而直接証明了ECT的增加排鉀和体內醛固酮水平高低密切相关。 (三)碳酸酐酶抑制剂AAA,在去腎上腺大白鼠仍能表現其增加排鉀的作用,而加用DOCA后就更加明显,可見碳酸酐酶抑制及醛固酮均为影响远端腎小管鈉鉀交换的因素,但其中任何一个因素都非唯一因素,两者作用机制不同,却都能促进鈉鉀交换,故当两者同时存在时,排鉀作用就表現得最为明显。 (四)醛固酮对抗剂SL能糾正利尿药因加用DOCA后引起的排鉀作用,但不能直接对抗AAA所产生的排鉀增多,再次証明SL在鉀排泄上和DOCA也起着专一性的竞爭性对抗作用。

The free-radical addition reaction of malonic ester with a series of alkenes under the uniform conditions has been studied. The relationship between the yields and the structure of the alkenes, as expressed in terms of the inductive indices for the substituent groups on the ethylenic bond, has been found to be a reversed sigmoid ("S") curve. It indicates that this addition reaction is an electrophilic free-radical addition of the malonic ester radical, CH(COOC_2H_5)_2, to the alkene molecules.From the yield-inductive...

The free-radical addition reaction of malonic ester with a series of alkenes under the uniform conditions has been studied. The relationship between the yields and the structure of the alkenes, as expressed in terms of the inductive indices for the substituent groups on the ethylenic bond, has been found to be a reversed sigmoid ("S") curve. It indicates that this addition reaction is an electrophilic free-radical addition of the malonic ester radical, CH(COOC_2H_5)_2, to the alkene molecules.From the yield-inductive index (Ⅰ) curve the point corresponding to the / value for 50% yield (I_(50)) may be determined. With reference to this point, the trend of changes in yields and the ranges of high yields for different homologous series of alkenes and substituted alkenes can be compared. For example, it can be shown that for all the aliphatic alkenes-1, high percentages of yields can be obtained in this reaction; for a chloro-alkene to give high yield, the chlorine atom must be separated by at least two carbon atoms from the olefinic double bond; and for carboxyl substituted alkenes, the carboxyl group must be beyond three carbon atoms to the ethylene group.

在相同反应条件下,进行一系列烯烃与丙二酸二乙酯的加成反应,求得产率与烯烃结构间的定量关系,即反S型曲线.根据此结构关系可以推定此加成反应是由丙二酸二乙酯形成的自由基[·CH(CO_2C_2H_5)_2]对烯烃的亲电子性自由基加成反应. 从产率曲线可以确定在一定的反应条件下I_(50)点的位置.根据I_(50)值讨论各类烯烃同系物在反应中的产率变化,及可得高产率的结构范围.例如,可以推定所有脂肪α-烯的产率均高,在氯烷基代烯中,氯原子与双键至少应隔两碳原子,而在羧代烷基烯中,羧基应隔三碳原子,始能得高产率.

The present paper deals with the isolation of intact plastids and mitochondria from soybean cotyledons and seed buds. The method of isolation involved a combination of differential and sucrose density gradient centrifugation.

采用分部离心及蔗糖密度梯度离心相结合的方法分离纯化大豆子叶和幼芽完整质体和线粒体,并以质体标记酶——磷酸三碳糖异构化酶和线粒体标记酶——细胞色素C氧化酶,分析蔗糖密度梯度离心后质体和线粒体的分布和纯度,用电子显微镜检查分离质体和线粒体的完整性。结果指出大豆子叶和幼芽的质体,线粒体分别分布在蔗糖密度梯度1.22g/cm~3和1.18g/cm~3区,分离的质体和线粒体纯度都在95%以上,完整性也是令人满意的。
