JOURNAL FREE ACCESSSince effective ovo-cidal compounds are mostly volatile and offensively odorous, the streochemical theory of odor presented by J. E. Amoore in 1952 was examined to discover fragrant ovo-cides against Ascaris eggs. As the result of this study, it was found that Amoore's theory may be applied to odor but not to ovo-cidal activity, and that ovo-cides must have ovo-cidal groups in their molecules, and only Fujita's conceptional diagram is available for this purpose as previously presented by the author. During the course of this study, it was found that a mixture of allyl isothiocyanate and d-camphor is not only equivalently effective but comparativley fragrant, and that some fragrant compounds like floral anisaldehyde and piperonal having no element other than C, H and O are comparatively effective.View full abstractDownload PDF (996K) -

JOURNAL FREE ACCESSThe inhibition of human serum cholinesterase by lysergic acid diethylamide (LSD), lysergic acid amide (LAA), isolysergic acid amide (iso-LAA), lysergol and elymoclavine was investigated, acetylcholine was used as a substrate. The enzyme activity was assayed by colorimetric determination of residual acetylcholine in the incubation mixture. The 50 percent inhibition of the cholinesterase activity in human serum was observed with 6×10-4μM LSD, 3×10-2μM elymoclavine and 1×10-1μM lysergol. Only 20 per cent inhibition occurred with concentration of LAA or iso-LAA up to 2×10-1μM. These alkaloids were the competitive inhibitors of the enzyme to acetylcholine.View full abstractDownload PDF (498K) -

JOURNAL FREE ACCESSLysergic acid and clavine alkaloids in the extracts of 68 kinds of Convolvulaceae seeds were investigated by fluorophotometry, thin-layer chromatography, column chromatography and infrared spectrophotometry. Lysergic acid amide, isolysergic acid amide, lysergol and elymoclavine were identified as the alkaloidal components in nine morning glory seeds of horticultural varieties which were commercially available. The total alkaloid contents in these seeds determined by the colorimetric method with Van Urk reagent were 0.0003 to 0.0206% as lysergic acid amide.View full abstractDownload PDF (583K) -

JOURNAL FREE ACCESSIsolation and purification of α-amylase from human saliva were carried out by column chromatography on Sephadex G-25 and on DEAE-cellulose. A specific antiserum was obtained from rabbits by intramuscular administration of purified α-amylase mixed with equal volume of complete Freund's adjuvant. This antiserum showed positive reactions in agarose gel immunodiffusion against human saliva and purified α-amylase at the minimum protein concentration of 25 μg/ml and 10 μg/ml, respectively. The amylase prepared from human saliva, pancreas and Fallopian tube cyst showed different electrophoretic mobilities on thin-layer gel of agarose, but the antigenicity of each amylase preparation to the anti-α-amylase obtained above was identical. The anti-α-amylase inhibited 72 to 76% of the enzymatic activity of the amylases of human saliva, pancreas and Fallopian tube cyst fluid and 54 to 57% of the enzymatic activity of the amylases of human serum and urine. Human liver and seminal plasma amylases were not inhibited by this antiserum, suggesting that these enzymes are different structurally and immunologically from the amylases of human saliva, pancreas and Fallopian tube cyst fluid as well as human serum vand urine.View full abstractDownload PDF (1010K) -

JOURNAL FREE ACCESSFor the investigation of antioxidative effect of 2-BHA and its two oxidation products, the peroxide values of lard samples containing above compounds were measured by active oxygen method. Under the analytical conditions used in this experiment, 2-BHA and both of the oxidation products were effective in order of 2-tert-butyl-4-methoxyphenol > diphenyl ether compound > 3-tert-butyl-4-methoxyphenol > diphenyl compound. Antioxidative effect of these compounds were also estimated under solar and UV light irradiation and revealed to be in order of 2-tert-butyl-4-methoxyphenol > diphenyl compound > diphenyl ether compound.View full abstractDownload PDF (789K) -

JOURNAL FREE ACCESSFor the determination of bromvalerylurea in biological samples, charcoal column chromatography was used to remove lipid contaminant present in the extract. The acetone-extract (100-400 mg) was applied to a column of 1.0 g charcoal, and eluted with 100 ml of hexane-ether-isopropanol (90 : 10 : 1) to separate neutral lipid. Bromvalerylurea was quantitatively recovered by the subsequent elution with 30 ml of acetone-methanol (90 : 10) and submitted to gas chromatographic determination. This treatment could eliminate most part of lipid and improve the recovery of bromvalerylurea. The procedure was applied to the determination of bromvalerylurea in liver, kidney, brain and blood of perorally administrated rat, and the time-courses of bromvalerylurea concentration in these tissues were observed.View full abstractDownload PDF (542K) -

JOURNAL FREE ACCESSFor the Determination of mercury, benzene was a convenient solvent for the simplification of procedures. The reproducibility of mercuric ion determined was higher than the other procedures because of the removal of excess reagent and interfering metals of each 1.0 mg of Cu2+, Bi3+ and Sn2+ ions by washing of benzene layer with ammoniac solution of EDTA. The interference of up to 30 μg of Ag+ ion was also prevented by washing with sodium chloride solution. The digestion time of samples was shortened by the use of sulfuric acid, hydrogen peroxide and potassium permanganate, and the extraction with n-hexane could remove the residual fat attributable to low recovery of mercuric ion in the digestion.View full abstractDownload PDF (645K) -

JOURNAL FREE ACCESSThe paper electrophoretic method to separate and identify eight preservatives (salicylic acid, benzoic acid, sorbic acid, dehydroacetic acid, ethyl p-hydroxybenzoate, resorcinol, β-naphthol and p-chlorobenzoic acid), a sterilizer (nitrofurazone), and three artificial sweetners (saccharin sodium, sodium cyclamate and dulcin) was investigated by using 1% borax solution, Kolthoff buffer solution (pH 4.0 and 5.8) or Atkins-Pantin buffer solution (pH 10) as the electrolyte. The mobilities of the compounds were shown as the relative one to flavianic acid, and tabulated. All the compounds could be identified by selecting the electrolytes.View full abstractDownload PDF (426K) -

JOURNAL FREE ACCESSThe present official method for analysis of lead resulted from glazed potteries is defect in both sensitivity and reproducibility. For improvement of the analytical method, conditions for extracting lead were examined, that is, various glazed pottery samples were extracted with water, 4% acetic acid and 1% powderized green tea extract at 20° and 60°, respectively. Amounts of sodium, lead and magnesium in the extracts were analyzed by atomic absorption spectrophotometer, and that of aluminium was determined by aluminon method. It was proved that the best result was obtained by extracting glazed potteries with 4% acetic acid at 60° for 30 min.View full abstractDownload PDF (435K) -

JOURNAL FREE ACCESSIt had been found that the water supplied in a newly-build school house in M District in Gifu City was a little astringent, and formed greese like membrane on standing, which became cloudy by boiling. The source water of the supplied water proved to contain much of erosive free carbonic acid, which cause the dissolution of Ca, Mg from asbestos pipe, and Zn from zinc coated iron pipe into the supplied water. This phenomenon has been observed for more than 3.5 years since the beginning of water supply. The influence of feeding mice and golden fishes by the supplied water on their growth and living time were also observed.View full abstractDownload PDF (719K)
