Resultados imediatos da artéria torácica interna direita e artéria radial como segundo enxerto arterial em revascularização do miocárdioImmediate results of right internal thoracic artery and radial artery as the second arterial graft in myocardial revascularization Abstract Objective: We sought to compare early clinical outcomes in patients receiving a right internal thoracic artery or a radial artery as the second arterial graft in myocardial revascularization.Methods: We retrospectively studied 58 consecutive patients who underwent coronary artery bypass surgery and received both a left internal thoracic artery graft and either a right internal thoracic artery (n=20) or a radial artery graft (n=38), between January 2004 and March 2006. Hospital mortality, pleural drainage, operative time and postoperative complications were analyzed.Results: There were no significant preoperative differences between groups. There was only one (1.7%) in-hospital death which occurred in the Radial Group. Operative times was significantly higher in the Right Internal Thoracic Group (p-value = 0.0018), but were not associated with increased Intensive Care Unit stays, mechanical ventilation or other postoperative complications. We were able to perform significantly more distal anastomosis using the radial artery than the right internal thoracic artery (1.57 versus 1.05: pvalue =0.003).Conclusion: In our group of patients, the use of a right internal thoracic artery as a second arterial graft was associated with a prolonged operative time, but had no interference with the immediate clinical outcomes. 61MIANA, LA ET AL -Immediate results of right internal thoracic artery and radial artery as the second arterial graft in myocardial revascularization Braz J Cardiovasc Surg 2007; 22(1): 60-67

The adequate storage will reflect directly on the physical, physiological and sanitary quality of the forest seeds and consequently on the process of seedling production. In this sense, the determination of suitable conditions for the storage of the seeds using packages and environments accessible to the producer are essential. Therefore, the objective of this work was to evaluate different packages (glass, plastic bag and kraft paper) and environments (refrigerator, freezer and laboratory environment) for storing seeds of Tabebuia chrysotricha (Mart. Ex DC.) Standl. (ipe). The variables germination, normal seedlings, abnormal seedlings and dead seeds were evaluated every 30 days for six months. The storage of yellow ipê seeds can be carried out in a plastic bag in the refrigerator (up to 150 days) and in the freezer (up to 180 days) with up to 70% germination.
