    Notes: Abstract. To identify individual chromosomes of a frog karyotype by their fluorescence banding patterns, chromosomes were stained with actinomycin D and 4,6-diamidino-2-phenylindole (DAPI) after incorporation of BrdU during the late S-phase. The chromosomes of three Rana species which were selected for this study (R. ridibunda, R. lessonae and R. japonica) showed well-defined late replication bands. The fluorescence patterns obtained were the reverse of those produced by a 4Na-EDTA Giemsa-staining technique. Fluorescence patterns of the two water frog species (R. ridibunda and R. lessonae) were similar to each other, except for the different fluorescence of the centromeric heterochromatin, which gave extremely bright signals in R. ridibunda but no signal in R. lessonae. Experiments also showed differences between the fluorescence patterns of R. lessonae chromosome 13 in the Italian and Luxembourgian populations. These results sho w that the fluorescence replication banding using actinomycin D and DAPI is very effective in identifying individual frog chromosomes and detecting their structural changes.

    High-performance thin-layer chromatography of metal complexes ofmeso-tetrakis(p-tolyl)porphyrin on cellulose and silica gel (1984)

    Notes: Summary The migration behavior of metal complexes ofmeso-tetrakis(p-tolyl)porphyrin (TTP) are studied in HPTLC systems with cellulose and silica gel thin-layers and various organic solvents of relatively low polarity. The mobility of the metal complex tends to increase in the following orders of its central-metal elements: on cellulose, Mg(II)〈Zn(II)〈V(IV)〈(H)〈Pd(II)〈 Ni(II)≈Cu(II); on silica gel, Mg(II)〈V(IV)〈Zn(II)= (H)〈Ni(II)≈Pd(II)⩽Cu(II). Recommendable phase system for the separation of metal-TTP complexes is a combination of silica gel thin-layer with a carbon disulfide-m-xylene mixture though the complexes of Ni, Cu and Pd are not completely resolved.

    Notes: Summary The mixed ligand, metal complex (acetylacetonato) (thenoryltrifluoroacetonato) beryllium(II) has been isolated from a reaction mixture of bis(acetylacetonato) beryllium(II) and bis(thenoyltrifluoroacetonato)beryllium(II) in ethyl acetate by gel permeation chromatography using Shodex 801 gel column and ethyl acetate as the solvent.

    Reversed-phase, high-performance, thin-layer chromatography of metal tetrakis (p-tolyl) porphine complexes on octadecylbonded stationary phase (1985)

    Notes: Summary The metal complexes ofmeso-tetrakis (p-tolyl) porphine (TTP) are chromatographed on octadecyl-bonded silica gel thin-layer with various organic solvents of relatively high polarity used as the eluent. The mobility of the metal-TTP complex depends on its centralmetal, increasing in the order of Cu(II)〈Pd(II)≈NI(II)〈TTP free acid〈V(IV) as vanadyl〈Zn(II)〈Mg(II), although some irregularities are found with the different developing solvents used. The concept of Hildebrand's solubility parameter is applied to the discussion of the mobility of each compound, on the solvents used as the developer. Successful separation of the TTP compounds is performed by using a mixture of acetone and acetonitrile as the developer, although the Ni- and Pd-complexes are not completely resolved.
