    Notes: Summary Male Wistar rats were injected intraperitoneally (i.p.) with toluene alone, m-xylene alone, and in combination with both of them. Urinary excretion of hippuric acid or m-methylhippuric acid of rats injected with solvents of various concentrations was investigated from the end of the injections up to 48 h later, at appropriate intervals. The amounts of increased excretion of HA and m-MHA in 0–24h urine samples of the rats given simultaneous injections of toluene and m-xylene were not lower than those of the rats given single injections of toluene alone or m-xylene alone, in the same amount. Data indicated that simultaneous administration of toluene and m-xylene did not significantly interfere with the metabolism of toluene or m-xylene.

    Diurnal appearance, fine structure, and chemical composition of fatty particles inHeterosigma akashiwo (Raphidophyceae) (1987)
    Springer
    Protoplasma 137 (1987), S. 134-139 
    Details
    ISSN: 1615-6102
    Keywords: Chemical composition ; Fatty particles ; Fine structure ; Heterosigma akashiwo ; Triacylglycerol ; Vertical migration
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Summary In cells ofHeterosigma akashiwo cultured under a photoperiod of 12∶12 L∶D, one or several fatty particles have appeared, grew in size approximately the second hour of the dark period, diminished in size from the tenth hour of the dark period, and completely disappeared by the seventh hour of the light period. The particles, usually located on the side of the nucleus away from the flagellar bases, were partially surrounded by endoplasmic reticulum, but not bounded by a membrane. Lipids comprised 80% of the isolated particles fraction, proteins only 1%. Triacyl-glycerol occupied 80% of the acyllipids in the lipid fraction. Tetradecanoic, hexadecanoic, and hexadecenoic acids comprised 80% of the total fatty acids composition.
