    Notes: Abstract Abnormally high postabsorptive venous plasma glutamate levels have been reported for several diseases that are associated with a loss of body cell mass including cancer, human/simian immunodeficiency virus infection, and amyotrophic lateral sklerosis. Studies on exchange rates in well-nourished cancer patients now show that high venous plasma glutamate levels may serve as a bona fide indicator for a decreased uptake of glutamate by the peripheral muscle tissue in the postabsorptive period and may be indicative for a precachectic state. High glutamate levels are also moderately correlated with a decreased uptake of glucose and ketone bodies. Relatively high venous glutamate levels have also been found in non-insulin-dependent diabetes mellitus and to some extent also in the cubital vein of normal elderly subjects, i.e., in conditions commonly associated with a decreased glucose tolerance and progressive loss of body cell mass.

    Description / Table of Contents: Résumé Neuf espèces d'Acariens Macrochelidae [Macrocheles “glaber” (Müller),M. aestivus Halliday,M. mammifer Berlese,M. peniculatus Berlese,M. robustulus (Berlese),M. merdarius (Berlese),M. peregrinus Krantz,M. eurygaster Krantz,Glyptholaspis confusa (Foà)] ont été essayés comme prédateurs de 2 espèces de mouches évoluant sur bouses (Musca vetustissima Walker,Haematobia irritans exigua de Meijère). La capacité prédatrice des acariens varie pour chaque espèce de mouche seion le stade de développement de celle-ci: oeuf ou larves. Les acariens les plus gros sont en général des prédateurs plus efficaces que les plus petits. Le niveau de prédation dû àM. “glaber” surM. vetustissima varie aussi en fonction du stade de développement du prédateur et de sa proie.
    Notes: Abstract Nine species of macrochelid mites [Macrocheles “glaber” (Müller),M. aestivus Halliday,M. mammifer Berlese,M. peniculatus Berlese,M. robustulus (Berlese),M. merdarius (Berlese),M. peregrinus Krantz,M. eurygaster Krantz,Glyptholaspis confusa (Foà) were tested in the laboratory as predators of 2 species of dung-breeding pest flies (Musca vetustissima Walker,Haematobia irritans exigua de Meijere). The mites varied in their ability to attack the 2 fly species at both egg and larval stages. larger mites were generally more effective predators than the smaller species. The level of predation imposed byM. “glaber” onMusca vetustissima also varied with the developmental stage of both predator and prey.
