A capacidade de suprimento de potassio do solo, resposta da soja a adubacao potassica e o efeito residual foram determinados em um experimento no campo, conduzido, por doze anos consecutivos, em um Latossolo Humico de Santa Catarina. Os tratamentos constaram de quadro doses de K2o (0,80,160 e 320 kg ha), distribuidas a lanco e incorporadas ao solo, nas parcelas, somente no primeiro ano de cultivo; tres doses de k20 (0,40 e 80 kg ha), aplicada a lanco, anualmente, nas subparcelas, a partir do quinto ano de cultivo, e um tratamento adicional, com aplicacao anual de 40 kg ha de K2O, no sulco. A valiacao de K no solo e de rendimento de graos foram feitas anualmente. Nos primeiros quatro anos, nao houve resposta da cultura a aplicacao de K. A partir do quinto ano, as respostas a adubacao potassica anual foram crescente. Na media das doze colheitas, cada quilograma de K2O, aplicado ao solo no primeiro ano, resultou num crescimento medio de 18 kg ha de graos de soja. Uma aplicacao anual de 60 kg ha de K2o foi suficiente para manter a produtividade da cultura acima de 90% da producao maxima. |

Byrsonima intermedia is a species of bush popularly used to treat gastrointestinal disorders, such as gastric ulcers, gastritis, and diarrhea. Previous studies have revealed that the methanolic crude extract of B. intermedia leaves has gastroprotective and healing properties. In this new study, we specifically investigated two purified partitions, ethyl acetate (EtOAc) and water (AcoAq), obtained from the crude extract to characterize the antiulcer effects of these two partitions and the mechanisms of action of this medicinal plant. The healing effects of these partitions on the gastric and duodenal mucosa were assessed after ischemia-reperfusion (I/R) or acetic acidinduced injury. The involvement of tumor necrosis factor-alpha (TNF-alpha), interleukin 1β (IL-1β), interleukin 10 (IL-10), and myeloperoxidase (MPO) activity and glutathione (GSH) levels were determined. The antibacterial activity against Helicobacter pylori was evaluated using microdilution methods. The phytochemical analysis of AcoAq revealed a predominance of oligomeric proanthocyanidins and galloyl quinic esters, whereas EtOAc was found to contain concentrated flavonoids. Both partitions led to a significant reduction in gastric lesions, but AcoAq was more effective than EtOAc with regard to anti-Helicobacter pylori activity in addition to protecting the gastric mucosa against ethanol, non-steroidal anti-inflammatory drugs (NSAIDs) and duodenal mucosal damage induced by cysteamine. Additionally, both partitions were associated with a significant increase in gastric and duodenal healing and increased gastric mucosal GSH content after damage induced by acetic acid. On the other hand, after 6 days of treatment, EtOAc was more effective than AcoAq in ameliorating gastric damage upon initiation of the gastric I/R, which was accompanied by a significant reduction in the activity of gastric mucosal MPO, IL 1-β and TNFalpha, as well as an elevation in IL-10 and GSH content. These results demonstrate that the oligomeric proanthocyanidins and galloyl quinic esters present in AcoAq were more effective in the prevention of gastric and duodenal ulcers due to the antioxidant effects of these compounds, whereas the flavonoids present in EtOAc were more effective due to their anti-inflammatory activity on the gastric and duodenal tissue. All these results confirm that the rich phytochemical diversity of B. intermedia contributes to the pharmacological actions of this medicinal plant on the gastrointestinal tract in addition to its activity against H. pylori.
