ジャーナル フリーFrom Korean Xixin oil, euasarone (2, 4, 5-trimethoxy-1-allylbenzene), elemicin, 3, 5-dimethoxytoluene (orcinol dimethyl ether), and n-pentadecane were newly isolated. Saishinone reported in previous paper was clarified as a mixture of 3, 5-dimethoxytoluene and eucarvone. A substance tentatively designated as X or Y in a previous paper as being found in several oils of Asiasarum and Heterotropa genus plants was elucidated to be an artefact and found to be dibutylphthalate.抄録全体を表示PDF形式でダウンロード (522K) -

ジャーナル フリーAs a part of studies on the inhibitory effect of anserine and carnosine on cardiac movement, some β-alanyl-peptides were synthesized, and the physiological action of these peptides was compared with that of anserine and carnosine. β-Alanyl-L-glutamic acid showed following results : This peptide inhibited the movement of isolated heart of toads and rats, antagonized oxytocin in isolated rat uterus, contracted isolated small intestine of guinea pigs, and increased the mitochondrial oxidative phosphorylation of rat myocardium and incorporation of 32P into chick myocardium. Toxicity of this peptide was weak (3.36 g/kg). Distribution of 3H-β-alanyl-L-glutamic acid in rat organs was examined and it was found that the incorporation of radioactivity was higher in the prostate, seminal vesicle, and kidney, and lower in testis and in large and small intestines. The radioactivity from 3H-β-alanyl-L-glutamic acid in urine accounted for about 3/5 of the total radioactivity.抄録全体を表示PDF形式でダウンロード (783K) -

ジャーナル フリーIn order to examine the application of tablets of polyelectrolytes, crosslinked with divinylbenzene to a low degree, to disintegration agent, two kinds of materials with different degree of swelling, crosslinked polyacrylic acid and crosslinked polymethacrylic acid, were selected and their disintegration behavior was examined from the point of swelling and fluidity, in the disintegration of valnoctamide tablet, which is extremely difficult to disintegrate, in water, and in the presence of inorganic salts or dl-methylephedrine hydrochloride. Valnoctamide tablet added with crosslinked polyelectrolyte underwent more rapid disintegration than the control tablet, and the logarithm of disintegration time approximately decreased with increasing velocity of swelling in water. In the system with small degree of swelling, such as in the presence of a neutral salt, disintegration was found to be dependent on the product of swelling velocity and degree of equilibrium swelling was also found that such tablets underwent disintegration by the liberation of the constituent component particles from the surface of swollen tablets by a relatively small shearing force.抄録全体を表示PDF形式でダウンロード (653K) -

ジャーナル フリーIn order to examine the course of intravenously injected iron chondroitinsulfate phagocytized in the reticuloendothelial system and the iron in it utilized as hemoglobin iron, iron chondroitinsulfate labeled with 59Fe was injected intravenously in normal mice, in three different doses, and examinations were made on its systemic distribution, separation of 59Fe into hemin iron and non-hemin iron in liver and spleen, and periodical changes in non-hemin 59Fe in the fraction separated by the Yoneyama -Konno method from the liver and small intestine, and the following points were revealed. 1) Disappearance of 59Fe from blood immediately after intravenous injection of iron (59Fe) chondroitinsulfate, its incorporation into the liver, followed by its disappearance from the liver, and incorporation of 59Fe into erythrocytes all become rapid with decreased amount administered. 2). Introduction of 59Fe into hemin iron is not observed in the liver but the peak of 59Fe in the spleen during 8-96 hours after the intravenous injection is clearly due to the incorporation of 59Fe into hemin iron. 3) Formation of ferritin in the liver requires a certain time lag and there is a good correspondence between that and incorporation of 59Fe into erythrocytes. 4) 59Fe that has collected in the small intestine is partly excreted and its excretion rate is dependend on the dose administered but follows the first-order formula.抄録全体を表示PDF形式でダウンロード (676K) -

ジャーナル フリーSelectivity between linoleic and oleic acids in pressurized hydrogenation with copperchromium oxide catalyst was found to be satisfactory, though oleic acid is saturated in a small rate at 180°. Several factors involved were examined at constant pressures to obtain an overall view. Pressure effect was of approximately Freundlich type, zero-order kinetics with respect to concentration of linoleic acid is held still under 40 kg/cm2, with activation energy of 15 kcal/mole averaged for 1 and 40 kg/cm2 hydrogenations, while an upper limitation to hydrogenation rate with increase in the amount of catalyst was less acute than was found at one atmospheric pressure, and stirring effect was markedly lowered as pressure rose.抄録全体を表示PDF形式でダウンロード (575K) -

ジャーナル フリーThe effect of guanidine, hydrazine, tropolone, and 2-aminoethylisothiuronium (AET) derivatives on the incorporation of acetate-1-14C into cholesterol was examined in the rat liver homogenates. Incorporation of acetate-1-<14>C into cholesterol was inhibited to varying degrees by all of the test compounds. Among these compounds 1, 1'-decamethylenediguanidine dihydrochloride, carbonyl cyanide phenylhydrazone, phenylhydrazine hydrochloride, 5-nitrosotropolone, and 2-(2-aminoethyl)-1'(p-chlorophenyl) isothiuronium bromide hydrobromide showed potent inhibitory action. The inhibitory action of these compounds was not affected by adding ATP (10-5-10-3M) exogenously into the incubation system. This result suggests that these compounds have sites of action other than blocking the high energy-forming system in mitochondria.抄録全体を表示PDF形式でダウンロード (646K) -

ジャーナル フリーA new calcium-lowering factor extracted from bovine parotid and submaxillary glands by a urea-HCl-cysteine extraction was compared with a calcitonin fraction extracted from the porcine thyroid gland by the same method. The hypocalcemic activity of the extract from thyroid gland collected during autumn and winter was more potent than that collected during spring and summer. The extracts from parotid and submaxillary glands had a weak hypocalcemic activity (about 0.01 MRC units/mg) in rats but not hypocalcemic or leucocyte activity in rabbits as it is the case for parotin. These factors showed the same pattern of calcium lowering effect as calcitonin in time course studies. Consequently, these calcium-lowering factors obtained from salivary gland were different from parotin-like substances and appeared to be calcitonin-like substances.抄録全体を表示PDF形式でダウンロード (638K) -

ジャーナル フリーThe coloration reaction, the so-called Craven reaction, of 1, 2-and 1, 4-naphthoquinones, and their derivatives with active methylene compounds, such as cyanoacetic acid esters and malonic acid diesters, in ammoniac alkalinity, was examined. 2-Methyl-, 3-methoxy-2-methyl-, and 3-chloro-2-methyl-1, 4-naphthoquinones react with cyanoacetate under dehydrogenation, demethoxylation, and dechlorination, respectively, to give the same product, while 2-methyl-1, 4-naphthoquinone alone reacts with malonic acid diester. Hydrolysis of these condensates in alcohol was found to produce 2-methyl-1, 4-naphtho-quinone-3-acetic acid and its ester. Reduction of these condensates with zinc in acetic anhydride and hydrolysis of its product were carried out and structure of the end product was elucidated. The same condensation products were obtained from 2, 3 -dichloro-, 2-chloro-3-methoxy-, 3-acetoxy-2-chloro-, and 2-chloro-1, 4-naphthoquinones. Condensation of 1, 4-naphthoquinone under dehydrogenataion was presumed from mutual reaction of 1, 4-naphthoquinone derivatives. Since a 4-substituted condensation product is obtained from 1, 2-naphthoquinone, this reaction was found to progress under dehydrogenation, as in the case of the above 1, 4-naphthoquinone derivatives.抄録全体を表示PDF形式でダウンロード (773K) -

ジャーナル フリーExperiments were carried out to utilize coloration reaction in nonaqueous solvent for simple qualitative and quantitative analysis. In order to elucidate the coloration reaction between Bromophenol Blue, one of sulfophthalein series dyes, and various amines in ethyl acetate, the complex compounds was isolated and identified. Based on this fact, structural changes that caused color change of sulfophthalein series dyes were examined. It was thereby found that the color change was due to the quinoid structure by salt formation between the sulfone group and an amine in the. 1 : 1 bonding of the dye and amines, or by the formation of a resonance structure by a charge transfer between the amines and phenolic hydroxyl in the 1 : 2 bonding.抄録全体を表示PDF形式でダウンロード (609K) -

ジャーナル フリーThe spectrometric and fluorometric methods for quantitative determination of carpipramine in biological materials were investigated. Carpipramine in the urine, bile, and gastrointestinal tract of rats was measured from the absorbance at 250 mμ, where the absorption peak of carpipramine is present. The intensity of its fluorescence (excitation, 280 mμ; fluorescence, 400 mμ) depends on the pH of its solution, and intensity increased as its solution became more alkaline. Therefore, carpipramine in various tissues was measured from the fluorescence at 400 mμ in alkaline conditions. From these results, carpipramine can be determined with good recovery and reproducibility by the present method with the exception of adipose tissue.抄録全体を表示PDF形式でダウンロード (448K) -

ジャーナル フリーMetabolic fate of carpipramine in rats and rabbits was examined by chemical assay, and the effect of this drug on serotonin levels in rat brain was also investigated. When a small dose was given orally, its absorption from the gastrointestinal tract was rapid but its absorption rate decreased when a relatively large dose was given orally in rats. The concentration of this drug in plasma and other tissues of rabbits was usually higher than that in rats. Carpipramine was concentrated in the lung, liver, and spleen, but only a small amount of the drug was found in the brain in both animal species. The half-life of this drug in plasma was 0.9 hr for rats and 2.3 hr for rabbits. Its excretion in urine was about 2% of the administered dose and about 13% in the feces within 2 days after oral administration to rats. When carpipramine was administered intraperitoneally, serotonin levels increased and reserpine-induced release of serotonin was inhibited in rat brain.抄録全体を表示PDF形式でダウンロード (718K) -

ジャーナル フリーThe metabolic fate of carpipramine labeled with tritium was investigated in rats. Radio-active carpipramine was administered p.o. or i.p. at the dose of 50 mg/kg, or p.o. at 10 mg/kg; during the following 72 hr about 3% was excreted in the urine and 80% in the feces. The same results are obtained whatever the any of administration may be. Approximately 30% of the administered dose was also excreted in the bile during the 24 hr following oral administration. Little radioactivity was found in various tissues 72 hr after oral administration. When radioactivity in the feces and bile was extracted with chloroform, both rates of extraction were clearly different, Using thin-layer chromatography, some of the radioactive metabolites were established to be glucuronides.抄録全体を表示PDF形式でダウンロード (551K) -

ジャーナル フリーProperties of adsorbed water and characteristics of the swelling process of Sephadex xerogels were investigated. Thermogravimetric and differential thermal analyses showed that G-10 and -25 retained two kinds of adsorbed water, while G-50, -75, -100, and -200 only one kind. Characteristics of the swelling process were determined periodically by measurement of variations in volume caused by swelling of xerogels, and linear relations with two kinds of slopes were observed in the swelling characteristics, such as effective diffusion coefficient of water, D[numerical formula], and water regain of the gels. All the results concerning the swelling process, which agreed with the conclusion drawn from the thermal analysis, suggested that the G-series of Sephadex might be divided into two groups. Correlation between swelling characteristics and elution parameters of several food dyes and peptides during get filtration was examined. Plots of log D[numerical formula] vs. elution parameters of the solutes offered some indications regarding the separation of some dyes having similar formula weights.抄録全体を表示PDF形式でダウンロード (696K) -

ジャーナル フリーElectrokinetic potential of Sephadex G-10, -15, -25, -50, -75, -100, and -200 gel particles swollen with water was measured by the moving boundary electrophoretic method. Relationships were investigated between the ζ-potential and characteristics of swelling process in the xerogels, and elution parameters of several food dyes and peptides in gel filtration. It was found that the Sephadex gel particles have negative ζ-potential and its values increased in proportion to the increase of G-numbers, namely, water regain of the gels. This finding suggested that the values of ζ-potential was mainly related to the swelling degree of the gels. A different property between lower and higher G-number gels was shown on the basis of distinctive linear relationships between ζ-potential and swelling characteristics of the xerogels such as effective diffusion coefficient of water. Elution parameters observed in gel filtration of peptides increased relatively to the values of ζ-potential, while the those of several food dyes decreased through adsorption.抄録全体を表示PDF形式でダウンロード (563K) -

ジャーナル フリーThe colouring compounds of the pulp and peels of Trichosanihes cucumeroides MAXIM. gave same carotenoids patterns on thin-layer chromatography. Crystals of β-carotene and lycopene were isolated from peels, and β-carotene from pulp. From the experimental results of seasonal variations of the fruits pigments, it was observed that the green colour of the fruits depended upon the existence of chlorophyl though the principal carotenoid was β-carotene; colour changing from green to orange mainly depended upon the appearance of lycopene and γ-carotene beside β-carotene and changing from orange to red colour was due to the increasing of lycopene and γ-carotene.抄録全体を表示PDF形式でダウンロード (445K)
