An investigation of the rheological relationships between shear stress shear rate apparent bulk viscosity temperature was carried out by examining the viscous flow of slightly milled native Hevea rubber (i) The Eisenschitz's equation for non-Newtonian flow has been verified by the experiments on the dependence of shear rate on shear stress. By this equation, the apparent viscosity can be referred to the Newtonian viscosity η_0 (at σ=0). The parameter (G_i=3.30×10~5 dynes/cm~2), interpreted as an internal...

An investigation of the rheological relationships between shear stress shear rate apparent bulk viscosity temperature was carried out by examining the viscous flow of slightly milled native Hevea rubber (i) The Eisenschitz's equation for non-Newtonian flow has been verified by the experiments on the dependence of shear rate on shear stress. By this equation, the apparent viscosity can be referred to the Newtonian viscosity η_0 (at σ=0). The parameter (G_i=3.30×10~5 dynes/cm~2), interpreted as an internal modulus of rigidity, was found to be practically independent of temperature in the range of 50-90℃, thus agreeing with the results by treating Saunder and Treloar's data. (ii) For the shear rate dependence of apparent viscosity, when the number of Khun segments per unit volume was taken into account for the calculation of retardation time τ_1=2.84η_0 [J_e]_∞, the Debye-Bueche's equation was found to be able to fit into our data at moderate low shear rates. The values of steady-state elastic compliance [J_e]_∞ were determined by elastic-recovery experiments. Furthermore, the internal shear modulus Gi could be thus calculated by combining the Eisenschitz's equation with the Debye-Bueche's one. (iii) From the experiments on the temperature dependence of viscous flow under various stresses, the apparent activation energy ΔE_η was found to be 12.7 kcal/mole; and therefrom, by estimation, the unit of flow-the Eyring segment would be 30 carbon atoms long. All determinations of the flow rate under constant stress were carried out in a Hppler parallel-plate plastometer, used as a viscoelasticity-rheometer according to the theory developed by Dienes.

β-Dichroine is one of the three alkaioids isolated by Chou et al. from Dichroa febrifuga Lour., a Chinese antimalarial herb. The antimalarial activity of this alkaloid has been shown to be 50 times that of quinine. Besides, many other aspects of the pharmacology of the dichroines have been described. This paper reports a method for the determination of β-dichroine in biological materials and the absorption, distribution, and excretion of this alkaloid in rats.

β-Dichroine is one of the three alkaioids isolated by Chou et al. from Dichroa febrifuga Lour., a Chinese antimalarial herb. The antimalarial activity of this alkaloid has been shown to be 50 times that of quinine. Besides, many other aspects of the pharmacology of the dichroines have been described. This paper reports a method for the determination of β-dichroine in biological materials and the absorption, distribution, and excretion of this alkaloid in rats. The biological materials (tissue homogenates, blood, urine, bile, and diluted faeces) were saturated with sodium chloride and extracted with chloroform at pH9. The chloroform layer was reacted with methyl orange reagent and the β-dichroine content deterined colorimetrically. This method was shown to possess a high degree of specificity for β-dichroine in tissues. Since normal excreta contains substances which behave similarly as β-dichroine, an eight-plate countercurrent distribution analysis was applied to study the excretion of the alkaloid. When given orally to rats,β-dichroine disappeared rapidly from the gastro-intestinal tract since one hour after a dose of 10 mg/kg only 58% of the administered dose could be recovered from the GI-tract. However, about 30% still remained four hours after administration of the drug. One hour after β-dichroine was given intravenously to a rat, the highest concentration was found in the kidneys. Moderate levels were found in the heart, spleen, liver, fat, and muscle, whereas very low levels were present in the blood. Only 16% of an administered dose was excreted in the urine in a 24-hour period. Very little was excreted in the faeces and no β-dichroine was found in the bile.

本文报告用甲基橙法并结合反流分布法,测定常山碱乙在大鼠体内的吸收、分布和排泄。这些结果表示常山碱乙口服后在胃肠道消失很快,1小时已消失40%,但4小时仍有30%存在。服药后大鼠都出现精神抑制和致泻症状。一鼠在给常山碱乙7.5毫克后不到4小时已死亡。可见常山碱乙在胃肠道能很好地吸收。常山碱乙静脉注射后很快离开血液,其分布以腎最高,心、肝、肌肉、脂肪及脾次之。但血中水平很低,给药后1小时平均每毫升血只含2微克。常山碱乙进入体内后,只16%左右以原形由尿排出体外,粪中只有极少量,而胆汁中几乎没有。

In reference to a theorem proved by Sugawara and Kanazawa together with recent studies of asymptotic behaviour by Omnes, the subtration in the dispersion relations of Gi(t) and Ti,(t) is discussed. The contributions to the r,(t) and Fπ,(0 by the "far away" singularities are accounted for more carefully; the results so obtained seem to agree pretty well with both the electric and magnetic isotopic vector form factors; the Ti,(t) satisfies the requirement proposed by Vick from the analysis of π-N scattering...

In reference to a theorem proved by Sugawara and Kanazawa together with recent studies of asymptotic behaviour by Omnes, the subtration in the dispersion relations of Gi(t) and Ti,(t) is discussed. The contributions to the r,(t) and Fπ,(0 by the "far away" singularities are accounted for more carefully; the results so obtained seem to agree pretty well with both the electric and magnetic isotopic vector form factors; the Ti,(t) satisfies the requirement proposed by Vick from the analysis of π-N scattering data. Our calculation also shows that the total isotopic vector charge and magnetic moment are mainly due to the 2π intermediate state contribution; it is very probable that there exist no core point charge and magnetic moment at all.

本文根据Sugawara和Kanazawa所证明的一个定理和Omnes关于渐近行为的研究,讨论了Gi(t)和Гi(t)色散关系的減出问题。比较仔细地考虑了Гi(t)和Fπ(t)中远区奇异性的贡献,所得的结果可以同时很好地符合电形式因子和磁形式因子。其中Гi(t)并满足Vick从πN实验分析中所提出的要求。计算结果还表明,核子的矢量总电荷和总磁矩绝大部分是由2π中间态贡献的,核子的核心点电荷和点磁矩很有可能等于零。
