Many plant crude extracts and their isolated compounds are the most attractive sources of new drugs and show promising results for the treatment of gastric ulcers. Austroplenckia populnea is commonly known as "marmelinho-do campo, mangabeira-brava, mangabarana and vime" and it has been used in folk medicine as anti-dysenteric and anti-rheumatic. Powdered bark wood (3.25 kg) was macerated with aqueous ethanol (96%) and the extract was concentrated under reduced pressure to yield 406 g of crude hydralcoholic extract. The hydralcoholic extract was suspended in aqueous methanol and partitioned with hexane, chloroform and ethyl acetate (EtOAc) in sequence, yielding 8.0 g, 9.5 g and 98.17 g of crude extracts, respectively. Chromatography of the hexane extract over a silica gel column led to the isolation of the triterpene populnoic acid. The oral administration of hydralcoholic, hexane, chloroform and EtOAc extracts (200 mg/kg) decreased the ulcer lesion index (ULI) by 83.15%, 46.87%, 32.2%, 68.12%, respectively. Oral administration of populnoic acid (100 mg/ kg) diminished the ULI by 55.29%. All the obtained results were significant in comparison with the negative control, with exception of the chloroform extract.

Objective: Getting to know the nursing care for the postoperative cardiac surgical patient, with or without cardiopulmonary bypass. Method: It is an integrative review done using BIREME and Scielo databases. Results: Most scientific articles were developed by nurses, 7 (60%), followed by 5 (40%) articles developed by doctors. It is observed that the majority of scientific articles were published in 2012, by nursing professionals, developed with quantitative and qualitative analysis. Conclusion: We conclude that the systematization of nursing assistance is of utmost importance since the preoperative until the postoperative period of cardiac surgery and among the alternative means of recovery from cardiovascular damage, the procedure with cardiopulmonary bypass, though it brings some complications, it is still the most effective.Descriptors: Cardiac surgery, Caring, Nursing. de los artículos científicos. Se observa que la mayoría de los artículos científicos fue publicada en 2012, por profesionales de enfermería, desarrollados con análisis cuantitativa y cualitativa. Conclusión: Se concluye que la sistematización de asistencia de enfermería es de extrema importancia desde el período pre-operatorio hasta el pos-operatorio de cirugía cardíaca y de entre los medios alternativos para la recuperación del daño cardiovascular, el procedimiento con circulación extracorpórea, aunque pueda traer algunas complicaciones, aún así es el más efectivo.
