DMSO is frequently used as carrier solvent in toxicological experiments due to its exceptionally low toxicity and environmental impact and also to achieve more effective dispersion of the toxicants. Aquatic toxicity studies of DMSO on the respiratory rates and the biochemical constituents of muscle and liver in catla revealed minimal lethality and negligible effect on the physiology of the test organism. This study helps in the choice of percentage of the carrier solvent that can be used in the preparation of toxicants for any toxicological studies involving fish.Keywords

Cobaloximes of the types Trans- BH2[Co(dmgH)2X], where dmgH- = Dimethylglyoximate, X- = Cl- or Br- and Trans-[Co(dmgH)2(H2O)I].B where, B = Piperazine (Pp) or 2-(N-Tert-butylamido)piperazine (t- Bu-PpAM) were prepared and characterized by TG/DTA, FABMS UV-visible, IR, NMR spectra and XRD studies. All the cobaloximes were screened against microorganisms for their antimicrobial activity and compared with streptomycin as standard. The free ligands viz., Pp&t- Bu-PpAM, showed antimicrobial activity in the order: Pp < t-Bu-PpAM. Most of the cobaloximes were found to be more active than the corresponding ligands such that the antimicrobial activity order for the axial halides was found to be Cl- > Br- > I - for cobaloximes having piperazine where as in the case of cobaloximes having 2-(N-Tertbutylamido) piperazine the antimicrobial activity order was found to be reversed as Br - > Cl- >I- .Keywords
