Gastroprotective effect of Cissus sicyoides (Vitaceae): Involvement of microcirculation, endogenous sulfhydryls and nitric oxide

Aim of the study: Cissus sicyoides L. is a medicinal plant popularly known in Brazil against various diseases and the research interest in this plant is justifiable because of its potential medicinal value in stomachache and gastric ulcer.Materials and methods: The methanolic extract obtained from the leaves of Cissus sicyoides (Cc) was evaluated for the ability to protect the gastric mucosa against injuries caused by necrotizing agents (0.3 M HCl/60% EtOH, absolute ethanol, piroxicam and pylorus ligature) in rodents. We also evaluated microcirculation, antioxidant action and participation of NO (nitric oxide) and sulfhydryls (SH) groups in the Cc gastroprotective action.Results: Administration of Cc significantly reduced gastric lesions induced by different ulcerogenic agents in rodents. This extract administered by oral route significantly increased gastric volume without exerting antisecretory effect. The Cc effect involved an increase of the defense mechanism of the gastrointestinal mucosa such as NO and SH groups that prevent and attenuate the ulcer process. The Cc also has antioxidant property against oxidative stress but does not modify microcirculation response in gastric mucosa.Conclusions: These results confirmed the traditional use of Cissus sicyoides for the treatment of gastric ulcer.

Cartas pessoais entre crianças brasileiras, portuguesas e angolanas

This article analyzes the data resultant of the accomplishment, between 2008 and 2009, of an extension and research project on the international exchange of letters between teachers and students from elementary schools in the towns of Garça and Marília, São Paulo State, Brazil, with a school in the city of Azaruja, Portugal and another in the city of Luanda, Angola. It was developed by a team of students and teachers, UNESP, Marília, in order to promote the exchange via personal letters for that students, between 8 and 9 years old, could take possession of the written language, in this case Portuguese, and understand it as an instrument steeped in culture. The choice of this kind in the world of the epistolary genre was made because it promotes the participation of the Other in the configuration of dialogic relations in the elaboration of the statements, taken as a reference in a Bakhtinian conception of language. It aimed to (1) point, in the letters exchanged between teachers and students between the Portuguese, Brazilians and Angolans in the early years, the evidence of authorship linguistic behavior that could signal the beginning of autonomy in the use of the written modality of language, or signs of submissive behavior; (2) reveal the cultural content of language tools used to construct indicators listed on the customs of each people, including those constituting school doings. For the generation of data were used principles of action research, which enabled direct action, along with Brazilian teachers, and indirectly, in the case of the foreign teachers. From the analysis of the corpus of research - letters exchanged between teachers and students - it is clear that the appropriation of language as a speech act realized in human relations makes the old personal correspondence a powerful instrument of development in the area of the written language.
