A intenção do trabalho é valorizar os fundamen tos da poesia como elementos imprescindíveis ao processo de conhecimento. Baseia-se em depoimentos tomados em en trevistas, dos quais.busca a apreensão de mecanismos pes soais que garantam a elaboração livre do pensamento, aln da que no espaço institucional escolar. Para tanto, vale- se, como linha auxiliar na interpretação dos depoimentos, da observação de fatores limitadores da expansão poética na escola. O trabalho é escrito em linguagem que se aproxi ma da linguagem poética o que proporciona ao leitor a opor tunidade de formulação pessoal do cçmcei to. Desse modo, pretende ser coerente à proposta de valorização da intui çao como base necessária ao conhecimento. -

Metronidazole is a nitronidazolic antibiotic used in veterinary medicine to the treatment of a variety of diseases. The cause of metronidazole neurotoxicity has not been determined. We report the case of a dog, female, Teckel, five-year-old, with a history of dorsiflexion of the tail, ataxia, muscle stiffness, recumbency, vertical nystagmus, apathy and anorexia, which was being medicated for seven days with metronidazole in a dose higher than the maximum recommended, and the neurological signs began after this period. Neurological signs were consistent with central vestibular dysfunction caused by metronidazole, such as ataxia and vertical nystagmus. In addition to the neurological changes, the clinical signs of anorexia and apathy are consistent with the administration of excessive doses of the medicine. The diagnosis of metronidazole-induced toxicosis is based on the history of normal to increased doses, clinical signs and resolution after discontinuation of the drug. In general, the prognosis is good after drug withdrawal and early diagnosis. Some dogs may die and others may recover completely. The neurotoxicosis has disappeared after the suspension of the medicine and supportive treatment. Veterinarians must be aware of potential complications associated with the use of this medicine, as well as limit their chronic use or high doses for the most severe cases, and diagnose the problem as quickly as possible to institute an early treatment.

One of the primary objectives of endodontic treatment of teeth with pulp necrosis is the elimination of microorganisms from the root canal system, as effectively as possible, especially in cases with chronic periapical lesions. AIM: The purpose of this study was to analyze the response of the periapical tissue of dogs' teeth with chronic periapical lesions to endodontic treatment performed with utilization of metronidazole, calcium hydroxide, and an association of both as root canal dressings. METHODOLOGY: Forty root canals were submitted to pulpectomy and the root canals were kept exposed to the oral environment for 6 months. Then, they were submitted to biomechanical preparation and divided into 4 study groups with 10 specimens: group I - no root canal dressing; group II - calcium hydroxide; group III - metronidazole; group IV - calcium hydroxide associated to metronidazole. After 15 days, the root canals were filled with Fill Canal sealer. After 90 days, the animals were killed and the especimens processed for histological analysis. RESULTS: Calcium hydroxide dressing provided a significantly better outcome compared to other experimental groups (α = 0.01). Also, the results of the association of metronidazole and calcium hydroxide were similar to those observed for the metronidazole group. The worst results were obtained by the no root canal dressing group. CONCLUSION: The use of metronidazole alone or associated with Calcium hydroxide, did not improve periapical healing when compared to Calcium hydroxide dressing.
