Arabinoxylan oligosaccharides (AXOS) are studied as food compounds with prebiotic potential. Here, the impact of consumption of breads with in situ-produced AXOS on intestinal fermentation and overall gastrointestinal characteristics was evaluated in a completely randomized, double-blind, controlled, cross-over study. Twenty-seven healthy volunteers consumed 180 g of wheat/rye bread with or without in situ-produced AXOS (WR(+) and WR(-), respectively) daily for 3 wk.

A dual origin, by both immigration of blood monocytes and local proliferation has been reported for macrophages, which are heterogeneous in several aspects. Until now few studies have focussed on renewal of macrophages. Therefore, in this study macrophage renewal by local proliferation has been studied in the spleen.

The selective modulation of carboplatin [diammine(1,1-cyclo-butanedicarboxylato)platinum(II)]-induced myelotoxicity was investigated in mice, using the protective agent WR2721 [S-2-(3-aminopropylamino)ethyl-phosphorothioic acid, ethiofos]. In female BALB/c mice, WR2721 (200 mg/kg intraperitoneally, i.p.

To study the regulation of macrophage (m phi) heterogeneity at bone marrow level, we developed a liquid culture system in which bone marrow-derived soft-agar colonies were expanded in the presence of colony-stimulating factor-1 (CSF-1). Several cloned m phi precursor cells were established as CSF-1-dependent cell lines, and were analyzed for morphological, phenotypic and functional characteristics. The continuously proliferating cell lines expressed both immature and mature m phi markers.
