Abstract: total bacterial counts (32°c and 5°c) and most probable numbers (mpn) of coliform organisms and e. coli were determined for samples of three retail bovine meat cuts and cutting and boning equipment three supermarkets. in the oldest of these, total counts were higher on meat cuts prepared in the cutting room than on meat boned in the packing plant. total counts were generally high on the equipment (higher for incubation at 32°c), with the wooden surfaces (tables, cutting boards) showing significaitly higher numbers than the metallic ones (eletric saw, knives). no differences could be found between counts on "clean" equipment and counts on equipment being-used. coliform organisms were generally present; when meat samples were tested for this group of bacteria and for e. coli, it was found that 96% of the samples were positive for both.

Abstract: the aim of this paper was to establish the relation between the kidney ecobiometry with atlanto-coccyges distance (acd) and height (h) in adult healthy dogs, to obtain normality parameters for assessment of renal size and volume, as well as establish reference values to evaluate kidney blood perfusion by the resistivity index (ri) and pulsatility index (pi) of main renal artery. the study was applied at 22 adult dogs, 11 males and 11 females. previously, the dac and h of all animals were measured. for ultrasonographic examination, the ultra-sound system hdi 4000 philips equipped with a multi-frequency microconvex transducer, color doppler and spectral doppler devices was used. the animals were placed into right or left lateral decubitus position, in agreement with the kidney to be assessed. the longitudinal (ld) and dorsoventral diameters (dvd) of kidney were measured in longitudinal plane, and the transverse diameter (td) was determined in transversal section. the renal volume (v) was automatically calculated by the ultrasound software. with triplex doppler, the ri and pi of right and left main renal arteries were obtained. all data were represented in mean ± sem. linear regression analyses were performed with renal ld, dvd, td and v as dependent variable, and acd and h as independent variable. ri and pi were compared between right and left renal arteries with student's t-test. the ld, dvd, td (cm) and v (ml) mean measurements for the left and right kidneys were: 5.24±0.27, 3.07±0.15, 3.07±0.9, 28.01±3.4 and 4.50±0.19, 2.88±0.14, 2.71±0.15, 21.27±2.6. all regression analyses were significant for the intercept and regression coefficient (p<0.01). there were statistical differences on ri and pi means between right and left renal arteries (p=0.001). the ri and pi means of left and right renal artery obtained were: 0.62±0.08 and 1.34±0.18; 0.70±0.06 and 1.62±0.13. the data obtained in the present paper can be used as parameters for evaluation of the renal size, volume

Abstract: OBJETIVO: Análise comparativa dos resultados hospitalares em pacientes infartados reperfundidos por meio de uma interven o coronariana percutanea de resgate ou primária. MéTODOS: Selecionados pacientes consecutivos, submetidos a uma interven o percutanea no infarto do miocárdio (< 24h), entre 1997 e 2000, incluídos no registro nacional multicêntrico CENIC, comparando os resultados hospitalares, entre aqueles submetidos ao procedimento de resgate (n=840) ou primário (n=8.531). RESULTADOS: Os pacientes que realizaram interven o de resgate eram significativamente mais jovens, com infarto anterior, associado à presen a de disfun o ventricular, porém com menor porcentual de doen a coronariana multiarterial, comparados aos primários. As taxas de implante de stents foram similares (56,9% vs. 54,9%; p=0,283), mas o sucesso do procedimento foi menor nos casos de resgate (88,1% vs. 91,2%; p<0,001), cursando com maior mortalidade (7,4% vs. 5,6%; p=0,034), comparado à interven o primária; nova revasculariza o (< 0,5%), cirurgia de emergência (< 0,3%) e reinfarto (< 2,6%) foram similares. A análise multivariada identificou o procedimento de resgate como preditor de mortalidade ao final da fase hospitalar [RC (IC=95%) = 1,60 (1,17-2,19); p=0,003]. CONCLUS O: Neste registro nacional, a interven o de resgate apresentou uma maior mortalidade hospitalar, comparada ao procedimento primário.
