    Notes: Abstract In Schwann cells, the transmembrane glycoprotein β-dystroglycan composes the dystroglycan complex, together with the extracellular glycoprotein α-dystroglycan which binds laminin-2, a major component of the Schwann cell basal lamina. To provide clues to the biological functions of the interaction of the dystroglycan complex with laminin-2 in peripheral nerve, the expression of β-dystroglycan and laminin-α2 chain was studied in rat sciatic nerves undergoing axonal degeneration and regeneration as well as in normal condition. In normal sciatic nerve, immunoreactivity for the cytoplasmic domain of β-dystroglycan was consistently and selectively localized in the Schwann cell cytoplasm underlying the outer (abaxonal) membrane apposing the basal lamina. While β-dystroglycan expression was gradually down-regulated in Schwann cells losing contact with axons during axonal degeneration, it was progressively up-regulated as the regenerating process of ensheathment and myelination proceeded during regeneration. Interestingly, β-dystroglycan expression, when detectable, was always restricted to the Schwann cell cytoplasm beneath the outer membrane apposing the basal lamina during both axonal degeneration and regeneration. Furthermore, laminin-α2 immunoreactivity roughly paralleled that of β-dystroglycan during both axonal degeneration and regeneration, indicating that the expression of β-dystroglycan and laminin-α2 is induced and maintained by the Schwann cell contact with axons. Our results indicate that the dystroglycan complex is involved in the adhesion of the Schwann cell outer membrane with the basal lamina and suggest that the dystroglycan complex may play a role in the process of Schwann cell ensheathment and myelination through the interaction with laminin-2.

    Notes: Summary Thin-layer chromatographic behavior of 49 inorganic ions on cellulose phosphate (P-cellulose) has systematically been surveyed with binary solvent mixtures consisting of sulfuric acid and an organic solvent such as methanol or acetone. The Rf values of many bivalent and monovalent ions as well as Te(VI) decrease on the P-cellulose layer with an increasing concentration of the organic solvent. Polyvalent ions which form strong phosphato-complexes and precipitate insoluble sulfate are strongly retained on P-cellulose. Oxy-anions, Au(III) and Pt(IV) are not adsorbed on the cellulose to any great extent. Feasibilities of the separation of multicomponent mixtures are demonstrated on the P-cellulose layer.

    Notes: Summary The thin-layer chromatographic behavior of 49 inorganic ions on polyethyleneimine (PEI) cellulose has been investigated in hydrochloric acid media (0.01–1.0 mol dm−3). The sorption on the cellulose decreases with increasing acid concentration for most of the ions, but As(III), Ti(IV) and Te(VI) do not exhibit any Rf variation with the acid concentration. The Rf spectra of TI(I), Cd(II), Pb(II) and Zn(II) have a maximum. Ag(I), Bi(III), Nb(V), Ta(V), Mo(VI) and W(VI) are retained tightly on the layer, due to either insoluble salt formation or extensive hydrolysis. The extremely low Rf values of Hg(II), Pd(II), Au(III), Ru(III) and Pt(IV) are accounted for by stability of their chlorocomplexes. Re(VII) distributes chromatographically, having moderate Rf values between 0.3 and 0.6, so that the selective separation of Re(VII) from the other ions is feasible.

    Notes: Summary The thin-layer chromatographic behavior of 49 inorganic ions on polyethyleneimine (PEI) cellulose, a weakly basic anion-exchanger, has been systematically studied in sulfuric acid and ammonium sulfate media (both 0.01–1.0 moldm−3). The sorption on the cellulose decreases with increasing concentration of the acid or sulfate for most of the ions and to a lesser extent for Hg(II), Bi(III), Th(IV), Nb(V), and U(VI). The Rf values of Pd(II), Ru(III), Au(III), Pt(IV), and Ta(V) are extremely low in both systems. Ba(II), Pb(II), Sb(III), Mo(VI), and W(VI) are also strongly retained on the layer. Oxy-anions such as As(III) and Se(VI) are not adsorbed on the cellulose to any great extent, but Re(VII) distributes on the plate with a Rf value of about 0.5. The characteristic retention on PEI-cellulose layer of several polyvalent ions, which form anionic sulfato complexes, can be observed in ammonium sulfate media. Possibilities for separations of analytical interest are also demonstrated in both systems.

    Notes: Summary Systematic study for the chromatographic behaviour of 49 inorganic ions has been carried out on cellulose phosphate layer in acetic acid and acetic acid — ammonium acetate media. Feasibilities for the effective separations of analytical interest are demonstrated on the 0.25 mm layer in both media.

    Notes: Summary Thin-layer chromatographic behavior of 58 inorganic ions on polyethyleneimine (PEI) cellulose has been systematically surveyed in hydrochloric acid — ammonium thiocyanate media. In this media most of the ions distribute chromatographically on the layer. Ag(I), Hg(II), Pd(II), Au(III), Bi(III), Ru(III), Pt(IV), Nb(V), Ta(V), Mo(VI), and W(VI) are strongly retained, while alkali earths(II), Mg(II), As(III), Ti(IV), and Te(VI) are not absorbed to any great extent in this system. An interesting correlation was found between the Rf values on PEI-cellulose in the thiocyanate media and the paramagnetic moment of the rare earths(III). An oddeven fluctuation against the atomic number is also found for the heavy rare earths(III). Chromatographic separation of many inorganic ions of analytical interest is demonstrated in this system.

    Notes: Summary Thin-layer chromatographic behavior of 49 inorganic ions has been systematically studied on polyethyleneimine (PEI) cellulose with solvent mixtures consisting of sulfuric acid and either methanol or acetone. The sorption of most ions on the cellulose increases with increasing methanol content in the solvent. The feature is noticeable for some ions which form sulfato complexes. The Rf values of Re(VII) slightly increase with increasing methanol content. Ba(II), Hg(II), Pb(II), Pd(II), Au(III), Bi(III), Ru(III), Sb(III), Pt(IV), Mo(VI) and W(VI) are strongly retained on the layer in methanol media. The behavior of most ions in the acetone system does not appreciably differ from that in the methanol system, but their Rf values are somewhat higher in acetone than in methanol. There are marked differences in the behavior og Hg(II), Au(III), Ru(III) and Re(VII) between the two systems. Feasibilities for the separation of many ions of analytical interest are also demonstrated in these systems.
