Novel Antioxidants Based on Selected 3d Metal Coordination Compounds with 2-Hydroxybenzaldehyde 4,S-Diallylisothiosemicarbazone.

2-Hydroxybenzaldehyde 4,S-diallylisothiosemicarbazone (HL) was synthesized and characterized by 1H, 13C NMR and FTIR spectroscopies. It exists in solution in two isomeric forms: cis (~25%) and trans (~75%). Six stable complexes were obtained by interaction of HL with copper(II), nickel(II), cobalt(III) and iron(III) salts: [Cu(L)Cl] (1), [Cu(L)NO3] (2), [Cu(3,4-Lut)(L)NO3] (3), [Ni(L)OAc] (4), [Co(L)2]Cl (5), [Fe(L)2]NO3 (6).

[Epidemiological study of salmonelloses in the Moldavia area].

A study was carried out on the epizooto-epidemiologic potential of certain domestic and wild animal species (cold-blooded), of the environment (residual waters) and food products, and their role in maintaining Salmonella endemics (others than the typhoid-parathyphoid group). Account was kept of the incidence of Salmonella and its circulation in subjects exposed to occupational risks and in the mass of the population, including those with clinically manifest salmonellosis and the clinically healthy carriers. The results showed the importance of domestic animals in maintaining the endemic (fowl 15%, swine 10%, bovine 5%).
