SUMMARY BACKGROUND: Cerebrovascular accident (or stroke) and ischemic heart disease are the the major causes of death in the world. It is estimated that about 85% of strokes are ischemic in origin. Reperfusion therapy in the acute phase of ischemic stroke with a recombinant human tissue plasminogen activator is effective, but some factors influence the success of this treatment. OBJECTIVE: The aim of this study was to evaluate clinical aspects and possible determinants for reperfusion after venous thrombolysis. METHODS: This is a retrospective, cross-sectional, observational study based on a review of hospital records of inpatients diagnosed with ischemic stroke treated with intravenous thrombolysis, the main outcome being reperfusion or not. RESULTS: Data from this study revealed a predominance of females in the group of reperfused patients and males in the non-reperfused group, both maintaining moderate severity on the National Institutes of Health Stroke Scale and admission without statistical significance (p>0.18). In addition, the mean admission severity score was 13.2 for the group of reperfused patients and 14.2 for those not reperfused, and the mean ejection fraction of both groups was within normal functionality, with a mean of 0.50 for reperfused patients and 0.62 for non-reperfused patients. CONCLUSION: We found an association between successful venous chemical thrombolysis reperfusion and lower mortality in patients with acute stroke.

ABSTRACT Rock powder and boiler ash are residues with a high potential for the fertilization of substrates to produce forestry seedlings. They are the source of macro and micronutrients, besides having an effect on soil pH. Therefore, this study aimed to evaluate the effect of the isolated application of rock power, boiler ash, dolomitic limestone and calcium carbonate on the reaction of soils with a sandy and clayey texture in the Cerrado Piauiense and on the growth and quality of ipê-amarelo seedlings. For this purpose, the pH values of soil in water and CaCl2 solution and the following morphophysiological parameters as indicators of the quality of forest seedlings were analyzed: length of the aerial part (LAP), and root (RL), stem diameter (SD), number of leaves (NL), total chlorophyll (TC), fresh mass of the aerial part (FMAP), fresh mass of the root (FMR), dry mass of the aerial part (DMAP), of the root (DMR) and total (TRM), and the DMAP/DMR and LAP/SD ratios and Dickson quality index (DQI). It was found that the rock powder and boiler ash residues change the pH values in clayey and sandy soils, and promote the growth and quality of ipê-amarelo seedlings.
