8-Hy-droxy-quinolinium tri-chlorido-(pyridine-2,6-di-carb-oxy-lic acid-κ ,,')copper(II) dihydrate.

The title compound, (CHNO)[CuCl(CHNO)]·2HO, was prepared by reacting Cu acetate dihydrate, solid 8-hy-droxy-quinoline (8-HQ), and solid pyridine-2,6-di-carb-oxy-lic acid (Hpydc), in a 1:1:1 molar ratio, in an aqueous solution of dilute hydro-chloric acid. The Cu atom exhibits a distorted CuONCl octa-hedral geometry, coordinating two oxygen atoms and one nitro-gen atom from the tridentate Hpydc ligand and three chloride atoms; the nitro-gen atom and one chloride atom occupy the axial positions with Cu-N and Cu-Cl bond lengths of 2.011 (2) Å and 2.

Norfloxacinium nitrate.

In the title salt [systematic name: 4-(3-carb-oxy-1-ethyl-6-fluoro-4-oxo-1,4-di-hydro-quin-olin-7-yl)piperazin-1-ium nitrate], CHFNO ·NO , proton transfer from nitric acid to the N atom of the piperazine ring of norfloxacin has occurred to form a mol-ecular salt. In the extended structure, N-H⋯O hydrogen bonds link alternating cations and anions into [100] chains, which are reinforced by aromatic π-π stacking inter-actions between the quinoline moieties of the norfloxacinium cations.

Tetra-aqua-(ethane-1,2-di-amine-κ,')nickel(II) naphthalene-1,5-di-sulfonate dihydrate.

The reaction of ethane-1,2-di-amine (en, CHN), the sodium salt of naphthalene-1,5-di-sulfonic acid (HNDS, CHOS), and nickel sulfate in an aqueous solution resulted in the formation of the title salt, [Ni(CHN)(HO)](CHOS)·2HO or [Ni(en)(HO)](NDS)·2HO. In the asymmetric unit, one half of an [Ni(en)(HO)] cation and one half of an NDS anion, and one water mol-ecule of crystallization are present. The Ni cation in the complex is positioned on a twofold rotation axis and exhibits a slight tetra-gonal distortion of the -NiON octa-hedron, with an Ni-N bond length of 2.

[The effectiveness of psychiatric rehabilitation of in-patients with schizophrenia].

Objective: To determine clinical and social indicators in in-patients with schizophrenia depending on their participation in psychiatric rehabilitation.

Material And Methods: One hundred in-patients were randomly assigned to receive either rehabilitation along with the standard pharmacological treatment or standard pharmacological treatment alone. Thirty-five patients from the main group and 39 patients from control group completed three-month participation in the study.

[Surgical treatment of low anterior resection syndrome].

Objective: To compare functional outcomes of various rectal reconstruction after total mesorectal excision.

Material And Methods: A prospective randomized trial included 90 patients with mid-to-low rectal carcinoma who underwent total mesorectal excision.

Results: There were 22 patients after J-pouch surgery, 30 patients with side-to-end anastomoses and 38 patients with end-to-end anastomoses.
