The Mannich bases derived from phenylacetone (Ⅰ,R=Me)and dibenzyl ke- tone (Ⅰ,R=CH_2Ph) prepared in our previous work gave expected semicarba- zones(Ⅱ) in neutral or slightly acidic media.Degradation of their methiodides gave vinyl ketone semicarbazones (Ⅲ).The structure of the latter was shown by their characteristic ultra-violet light absorption properties,and they gave in- tense absorption bands near 260 mμ.The pyrazolinecarboxamides (Ⅳ),if formed,would behave more like saturated semicarbazones such as Me·CO·CHMePh...

The Mannich bases derived from phenylacetone (Ⅰ,R=Me)and dibenzyl ke- tone (Ⅰ,R=CH_2Ph) prepared in our previous work gave expected semicarba- zones(Ⅱ) in neutral or slightly acidic media.Degradation of their methiodides gave vinyl ketone semicarbazones (Ⅲ).The structure of the latter was shown by their characteristic ultra-violet light absorption properties,and they gave in- tense absorption bands near 260 mμ.The pyrazolinecarboxamides (Ⅳ),if formed,would behave more like saturated semicarbazones such as Me·CO·CHMePh and CH_2Ph·CO·CHEtPh,which gave maxima located at about 230mμ.The vinyl ketone semicarbazones could not be converted to the cyclic compounds (Ⅳ) by treatment with concentrated sulphuric acid.It was recalled that Δ~2-isoxazolines,beside vinyl ketone oximes,were obtained by us previously from the degradation of Mannich base oxime methiodides. Both the dimethylamino(I:R=CH_2Ph,R'=Me) and the diethylamino(I: R=CH_2Ph,R'=Et) compounds gave the identical product (Ⅷ) on treatment with semicarbazide hydrochloride in the presence of excess sodium acetate.It was recalled that an abnormal compound,m.p.101-102,was formed by these two Mannich bases on treatment with hydroxylamine hydrochloride and sodium acetate.This product might be (Ⅶ),formed by elimination of a mole of hy- droxylamine from (Ⅸ),which is analogous to (Ⅷ). Treatment of the Mannich base (I,R=CH_2Ph,R'=Me) itself with sodium acetate gave dibenzyl ketone.This is the reverse change of the original Mannich reaction.However,its methiodide,on degradation with sodium hydroxide, gave a vinyl ketone which readily dimerised into a dihydropyran (Xa or Xb). Several expected pyrazolines were obtained from the Mannich bases and phenylhydrazine.Their ultra-violet light absorption characteristics were listed.

几个 Mannich 碱在中性或微酸性的情况下制成它们的缩氨基脲,其中一个Mannich 碱在碱性情况下形成一个含有两分子氨基脲的物质。那些 Mannich 碱缩氨基脲的季铵碱当在碱性情况下递降时生成乙稀酮的缩氨基脲,而不生成环状的化合物(Ⅳ)。从二苯甲基酮衍生的一个 Mannich 碱经醋酸钠作用后变为原来的1,3-二苯基丙酮,但这个 Mannich 碱的季铵盐经碱作用后成为乙稀酮,而这个乙烯酮迅速贰聚。几个4,5-二氢隣二氮杂茂自 Mannich 碱如预期地形成。上列许多产物的紫外线光谱曾经测定。

Wistar rats that had been kept on a normal diet for 1 week were put on a high-carbohydrate (80% of total calories)diet composed of starch,mainly in wheat flour,for 3 days.The fasting plasma insulin and triglyceride (TG) contents of these rats were higher than that of the normal dietary rats (p<0.01;P<0.01) After feeding the high-carbohydrate (CHO) diet for 6 days,the fasting plasma TC level was about 4 times higher,while the cAMP contents in plasma,muscle,and fat tissues were lower than that of the normal dietary...

Wistar rats that had been kept on a normal diet for 1 week were put on a high-carbohydrate (80% of total calories)diet composed of starch,mainly in wheat flour,for 3 days.The fasting plasma insulin and triglyceride (TG) contents of these rats were higher than that of the normal dietary rats (p<0.01;P<0.01) After feeding the high-carbohydrate (CHO) diet for 6 days,the fasting plasma TC level was about 4 times higher,while the cAMP contents in plasma,muscle,and fat tissues were lower than that of the normal dietary rats by 38%,45% and 32% (P<0.05 p<0.05; 0.1reverse change between plasma insulin level and the levels of plasma cAMP and liver Ac activity was observed.Based on the results of this study we suggest that the elevated level of plasma inaulin and decreased level of plasma cAMP in response to high-carbohydrate diet is likely due to the inhibitory action of insulin on tissue Ac,but not the activation of tissue cAMP-PDE (low km value).

The result of early study suggested that one of the important functions of calcium was to prevent the substances dissolved in the cytosol from leakaging, which was supported by several experiments. The events accummuinted recently indicated that the effect of calcium on the permeability for different substances depended on their coneentration.

The result of early study suggested that one of the important functions of calcium was to prevent the substances dissolved in the cytosol from leakaging, which was supported by several experiments. The events accummuinted recently indicated that the effect of calcium on the permeability for different substances depended on their coneentration. The distance between two hydrocarbon chains of membrane and hydrophibicity increased because of a low concetration of calcium in this case, which led to the reverse change of the permeability for water and nonelectrclyt. Constary, the high concentration of calcium caused the decrease of the distance between two hydrocarbon chains. the biomembrane became mere rigidit and reverased permeability of membrane for the substances mentioned above.

早期的研究证明钙具有维持生物膜的选择适性、防止可扩散细胞内含物外渗的作用,不少的实验也证明了这一论点。近年来的研究则认为钙的浓度不同对不同物质透过膜的性能大小的影响亦不同,低浓度的钙可使组成生物膜的两烃链之间的距离加大,膜亲水性增加,疏水性变小,从而造成水分及非电解质物质透性的反向变化,而高浓度的钙则使膜上两烃链距离变小,生物膜变硬,水分和非电解质透性均减小。
