Propriedades dos sistemas de numeração: uma sequência didática em uma abordagem histórica

This paper aims to describe the construction and validation of a notebook of activities whose content is a didactic sequence that makes use of the study of ancient numbering systems as compared to the object of our decimal positional numbering system Arabic. This is on the assumption that the comparison with a system different from our own might provide a better understanding of our own numbering system, but also help in the process of arithmetic operations of addition, subtraction and multiplication, since it will force us to think in ways that are not routinely object of our attention. The systems covered in the study were the Egyptian hieroglyphic system of numbering, the numbering system Greek alphabet and Roman numbering system, always compared to our numbering system. The following teachung is presented structured in the form of our activities, so-called exercise set and common tasks around a former same numbering system. In its final stage of preparation, the sequence with the participation of 26 primary school teachers of basic education

O espelho dos hieróglifos: da ruína das letras egípcias à sua reinvenção quimérica entre os séc. XV e XVII

Gastroprotective and antisecretory effects of Ailanthus excelsa (Roxb)

Ailanthus excelsa (Roxb), an Egyptian medicinal species highly important for treating numerous diseases, was investigated against experimentally induced gastric ulcer in rodents. We evaluated the gastroprotective effect of four extracts (petroleum ether, diethyl ether, chloroform, and methanol) of A. excelsa bark by using the ethanol-induced gastric lesion model. The pretreatment of animals with methanolic, petroleum ether, and chloroformic extracts (100 mg/kg, oral (p.o.)) from A. excelsa significantly reduced gastric lesion induced by ulcerogenic agent (56, 47, and 70%, respectively) when compared with animals pretreated with vehicle. However, the diethyl ether pretreatment led to the least gastric lesion damage (83%), similar to the standard antiulcer drug, cimetidine, at the same dose (100 mg/kg, p.o.). The lower effective dose of diethyl ether extract, as well as cimetidine, given by intraduodenal route, significantly increased the pH values and reduced the acid output of gastric juice. Sterols, triterpenes, and quassinoids are present in the diethyl ether extract of A. excelsa stem bark, which presented the best gastroprotective action among the studied extracts. Our study confirmed the traditional indications of A. excelsa for the treatment of gastric ulcer.
