This work evaluates effects of the sweetener with sucralose on the labeling of blood constituents with technetium-99m (99mTc), on the morphology of red blood cells (RBC) and on the biodistribution of sodium pertechnetate in Wistar rats. Animals were treated with sweetener for 8 days. Blood samples were withdrawn and the assay of labeling of blood constituents with 99mTc was performed. Blood cells (BC) and plasma (P) were isolated. Aliquots of BC and P were also precipitated, soluble and insoluble fractions separated. The radioactivity in each fraction was counted and percentage of incorporated radioactivity (%ATI) determined. Blood smears were prepared, fixed, stained and the qualitative and quantitative morphology of the RBC was evaluated under optical microscopy. In biodistribution experiments, sodium pertechnetate was administrated, organs and tissues isolated, radioactivity was counted and percentage of incorporated radioactivity per gram (%ATI/g) determined. The data showed no significant alterations in %ATI, morphology of RBC and in %ATI/g in the studied organs.

The aim of this work was to evaluate the effect of fenoprofen on the labeling of blood constituents with technetium-99m, on the morphology of red blood cells and on the plasmid DNA. Blood samples from Wistar rats were incubated with fenoprofen and the assay of labeling of blood constituents with technetium-99m (99mTc) was performed. Blood cells, plasma, soluble and insoluble fractions of blood cells and plasma were separated. The radioactivity in each fraction was counted and percentage of incorporated radioactivity (%ATI) was determined. Blood smears were prepared, fixed, stained and the qualitative and quantitative morphology of the red blood cells (RBC) was evaluated. Plasmid (pBSK) was incubated with fenoprofen with stannous chloride, and agarose gel electrophoresis procedure was carried out to evaluate genotoxic and the protection of this drug against stannous chloride effect on DNA. In conclusion, under the conditions used in this work, our data suggest that fenoprofen would not (i) affect the fixation of the 99mTc on the blood constituents, (ii) alter the RBC membrane and (iii) present genotoxic and redox effects.

The Camponotus subgenus Mayria is revised based on the analysis of both qualitative morphological characters and morphometric traits. The multivariate analysis combined the Nest Centroid (NC)-clustering method and Partitioning Algorithm based on Recursive Thresholding (PART) function to generate species hypotheses based on 19 continuous morphological traits of minor workers. The proposed species hypotheses were confirmed by cumulative Linear Discriminant Analysis (LDA). Morphometric ratios for the subsets of minor and major workers were used in species descriptions and redefinitions. In this study, 14 species are recognized, of which seven are newly described: C. lamosy sp. n., C. liandia sp. n., C. mainty sp. n., C. manabo sp. n., C. raina sp. n., C. sada sp. n., C. tanosy sp. n. Four species are redescribed: C. christi Forel, C. dromedarius Forel, C. lubbocki Forel, and C. repens Forel. The following are raised to species and redescribed: C. foersteri Forel stat. n., C. maculiventris Emery stat. n., and C. pulcher stat. n. The following are synonymized under C. foersteri: Camponotus cambouei Forel, syn. n.; C. christi ambustus Forel, syn. n.; C. christi ferrugineus Emery, syn. n. and C. pictipes Forel, syn. n. The following are synonymized under C. lubbocki: Camponotus lubbocki christoides Forel, syn. n. and C. lubbocki rectus Forel, syn. n. Also included in this revision are an illustrated species identification key, taxonomic discussions, images, and distribution maps for each species superimposed with the ecoregions of Madagascar.
