Prevalence of psychoactive substance use among acutely hospitalised patients in Oslo and Moscow: a cross-sectional, observational study.

Objectives: The use of psychoactive prescription medication is increasing in the general population. This is a cause for concern, particularly among the elderly, where physiological changes related to senescence increase the risk for adverse effects. While previous studies regarding psychoactive substance use have generally been population based, we sought to determine the frequency of such use among acutely hospitalised patients.

The edible mushroom Albatrellus ovinus contains a α-l-fuco-α-d-galactan, α-d-glucan, a branched (1 → 6)-β-d-glucan and a branched (1 → 3)-β-d-glucan.

Albatrellus ovinus, the sheep polypore, is a large, dense mushroom being rich in cell wall material. Polysaccharides were isolated by sequential extraction, enzymatic treatment and analyzed with respect to monosaccharide composition, glycosidic linkages by methylation and GC-MS as well as NMR spectroscopy. A fucogalactan composed of an (1 → 6)-α-d-galactan backbone with single α-l-Fucp residues attached at O-2 was identified in the hot water extract obtained after treatment with a protease and size exclusion chromatography.
