Marcos Carvalho Maia,José Cardoso Pinto,Antnio Ricardo Evangelista
Ciência Animal Brasileira , 2006,
Abstract: O milheto [Pennisetum americanum (L.) Leeke] foi cultivado em sucess o à cultura de feij o (Phaseolus vulgaris L.) no Departamento de Zootecnia da Universidade Federal de Lavras (UFLA). Avaliaram-se os teores de fibra e minerais de três cultivares de milheto (milheto comum, BN 2 e CMS 02), semeadas após a cultura do feij o das águas, sem nenhuma aduba o adicional, na safrinha, em quatro épocas de semeadura, com espa os de 20 dias, a partir de 22/2/1997, no delineamento de blocos ao acaso, em esquema de parcelas subdivididas, alocando as épocas nas parcelas principais e as cultivares nas subparcelas. A menor concentra o de FDN (66,85%) foi determinada na cultivar milheto comum. As cultivares de milheto n o diferiram em rela o ao teor de FDA; a média das três cultivares foi de 40,8%. De um modo geral, os teores de P e K na forragem de milheto diminuíram da época de semeadura 1 para a época 4, enquanto os teores de Ca e Mg apresentaram comportamento oposto. Sugere-se que, na regi o de Lavras-MG, o milheto seja semeado até meados do mês de mar o, na safrinha, em plantio de sucess o, utilizando-se as cultivares BN 2 e milheto comum. PALAVRAS-CHAVE: Aduba o residual, composi o química, época de semeadura, safrinha.

Abstract:

The purpose of this study was to evaluate the effect of intralesional Mesenchymal Stem Cells (MSC) on the treatment of experimentally induced articular chondral defects in horses, emphasizing the benefits of this application in veterinary medicine. Chondral defects were induced in the medial femoral trochlea of both hind limbs of four horses. Thirty days post induction; the horses were divided into two groups. The G1 was submitted to treatment with MSC and the G2 was the control group. Clinical evaluations, synovial fluid analysis and synovial Prostaglandin E2 (PGE2) assessment were performed prior to defects and fortnightly up to 120 and 150 days. Macroscopic, histopathological and histochemical evaluations were performed at the end of the experiment. The treatment with MSC reduced the intraarticular inflammatory process. The G1 showed lower PGE2 concentrations in the synovial fluid and greater percentage of mononuclear cells and lower percentages of lymphocytes and neutrophils. The treatment improved the macro and microscopic aspects of repair tissue. No difference was observed in the scores of lameness between the G1 and G2. The use of MSC in the treatment of chondral defects minimized joint inflammation, as confirmed by synovial fluid analysis. The treatment resulted in an improved repair tissue, verified by macroscopic examination, histochemical and histopathological analysis.

International Archives of Otorhinolaryngology , 2008,
Abstract: Introduction: The existence of malignant branchiogenic cyst has been controversial since it was first described. Most authors believe that it is actually a head and neck primary tumor cystic metastasis. Objective: Discuss the existence of malignant branchiogenic cyst. Case Report: A patient with a cystic mass in front of the sternocleidomastoideus muscle superior part, which was removed as a malignant branchiogenic cyst. However, the anatomopathological examination suggested it was an unknown primary tumor. The patient has been followed-up with periodic examinations without evidences of a primary tumor. Conclusion: Probably we will never know whether it was a malignant branchiogenic cyst or an unknown primary metastasis, due to diagnostic criteria overlapping.
