[Decorative repair and reconstruction of subtotal thumb and finger defect with trimmed toe flap transfer].

Objective: In partial loss of distal finger segment, a corresponding part of the toe tissue compound is harvested and transplanted for repair or reconstruction. This new procedure gives forth a new concept and is called decorative repair or reconstruction.

Methods: In a series of 77 patients with 88 thumb and/or finger subtotal defects in forms of lateral half, dorsal half or volar half composite tissue defects were reconstructed with lateral nail-skin flap, dorsal skin-nail flap or pulp flap taken from corresponding part of the toes.

[Synthesis of mixed complexes of lanthanum with 2,2-bipyridyl and 1,10-phenanthroline and study of the interaction of the complexes with DNA].

A mixed complex of La with 2,2-bipyridyl (dpy) and 1,10-phenanthroline(phen) was synthesized. Elemental analysis, IR and TGA of the complex were investigated, thus it was proved that the conformation of it was La(dpy)(phen)Cl3. The interaction of the complex with DNA has been studied also.

[Determination of DNA by fluorimetry with flow injection].

A highly sensitive fluorimetry determination of DNA is developed in this paper. The maximum fluorescence intensity was produced in the pH 3.05, with the maximum excitation and emission wavelength of 362 and 531 nm, respectively.
