Polynuclear and mixed-ligand mononuclear Cu(I) complexes with N-thiophosphorylated thioureas and 1,10-phenanthroline or PPh3.

Deprotonation of the N-thiophosphorylated thioureas RC(S)NHP(S)(OiPr)(2) (R = Me(2)N, HL(I); iPrNH, HL(II); 2,6-Me(2)C(6)H(3)NH, HL(III), 2,4,6-Me(3)C(6)H(2)NH, HL(IV), aza-15-crown-5, HL(V)) and reaction with CuI or Cu(NO(3))(2) in aqueous EtOH leads to the polynuclear complexes [Cu(4)(L(I)-S,S')(4)], [Cu(8)(L(II)-S,S')(8)], and [Cu(3)(L(III-V)-S,S')(3)]. The structures of these compounds were investigated by IR, (1)H, (31)P{(1)H} NMR, UV-vis spectroscopy and elemental analyses. The crystal structures of [Cu(4)L(I)(4)], [Cu(8)L(II)(8)], [Cu(3)L(III,IV)(3)] were determined by single-crystal X-ray diffraction.

Endoscopic magnetic cholecystodigestive anastomoses: personal technique for palliative treatment of distal bile duct obstruction.

A new type of endoscopic surgery (magnetic cholecystodigestive anastomoses) is presented as an alternative to conventional palliative treatment of mechanical obstruction with icterus located below the bile duct inlet. By means of endoscopic technique, two clinically usable methods of creating delayed magnetic cholecystogastric anastomoses and one modality of implanting cholecystoenteric and enteroenteric anastomosis have been worked out in the experiment conducted on 50 mongrels with mechanical icterus. Ring-shaped or rectangular magnets were implanted in the gallbladder through laparoscopic cholecystostomy.

[Endoscopic biliodigestive anastomosis with the use of magnets (experimental and clinical study)].

A new type of endoscopic operations--cholecystodigestive and choledocho-hepaticoduodenoanastomoses with the use of magnetic elements are suggested as an alternative to the traditional palliative methods of treatment of obstructive jaundice with the level of obstruction below the opening of the cystic duct. Two variants of establishing postponed compression cholecystogastroanastomoses were developed in experiments on a model of obstructive jaundice in 50 unbred dogs, a variant of cholecystoentero- and enteroenteroanastomoses with the use of endoscopic techniques, which may be conducted in clinical practice. To restore internal bile drainage the following operations were carried out on 16 patients: colecystogastroanastomosis (4), cholecystoduodenonastomosis (1), choledochoduodenoanastomosis (10), hapaticoduodenoanastomosis (1).
