Comparação da eficiência dos caldos de enriquecimento seletivo no isolamento de Salmonella Dublin 45
Silva,D.G.; Fagliari,J.J.; Garcia,T.B..
The aim of this study was to compare three different selective enrichment broths: Rappaport-Vassiliadis (RV), selenite cystine (SC) and Muller-Kauffmann tetrathionate (MKT) for Salmonella Dublin isolation from faecal samples of calf experimentally infected. The bacteriological procedure involved pre-enrichment stages in Hajna-GN broth (only for the samples inoculated in RV broth), selective enrichment, culture in modified brilliant green agar (BGA), presumptive biochemistry tests (using triple-sugar-iron agar and lysine-agar) and slide agglutination test with poli-O and poli-H Salmonella antiserum. The effects of enrichment temperatures using RV broth were also evaluated (37ºC and 42ºC). SC broth was significantly more efficient in the isolation of...

Local inhibition of nitrergic activity in tenotomized rats accelerates muscle regeneration by increasing fiber area and decreasing central core lesions 56
Seabra,A.D.; Moraes,S.A.S.; Batista,E.J.O.; Garcia,T.B.; Souza,M.C.; Oliveira,K.R.M.; Herculano,A.M..
Muscular atrophy is a progressive degeneration characterized by muscular proteolysis, loss of mass and decrease in fiber area. Tendon rupture induces muscular atrophy due to an intrinsic functional connection. Local inhibition of nitric oxide synthase (NOS) by Nω-nitro-L-arginine methyl ester (L-NAME) accelerates tendon histological recovery and induces functional improvement. Here we evaluate the effects of such local nitrergic inhibition on the pattern of soleus muscle regeneration after tenotomy. Adult male Wistar rats (240 to 280 g) were divided into four experimental groups: control (n=4), tenotomized (n=6), vehicle (n=6), and L-NAME (n=6). Muscular atrophy was induced by calcaneal tendon rupture in rats. Changes in muscle wet weight and total protein...
