ABSTRACT
Os autores apresentam sua experiência com 23 casos operados e nos quais foi feita revascularização do membro inferior por meio de derivaçöes em que a anastomose distal foi implantada num segmento isolado de artéria. A perviedade cumulativa no grupo em que foram usadas próteses (7 casos), a taxa foi de 21 'por cento'. Os resultados obtidos quanto à preservação do membro foram elevados, sendo de 81 'por cento' e 87 'por cento' respectivamente para as lesöes estáveis e instáveis.

A histochemical and autoradiographic study of the lining intestinal epithelium of the snake Xenodon merremii is reported. The absorptive cells present neutral polysaccharides, arginine, tyrosine, tryptophan, cysteine, alkaline phosphatase, acid phosphatase, ATPase, AMPase, esterase and RNA. There are histochemical differences between the goblet cells of the small and of the large intestine. Whereas in the former predominates the neutral polysaccharides and are found arginine, tyrosine, tryptophan and cysteine, in the latter predominates the sulfated polysaccharides (confirmed by the uptake of radioactive sulfur) and no amino acids were found.

Several histochemical tests were applied to the lining and glandular gastric epithelium of Xenodon merremii. Our observations, after discussion and interpretation, conducted to the following conclusions: 1. the surface epithelial cells, the neck cells, the body cells and the pyloric cells showed neutral polysaccharides, arginine, tyrosine, cysteine, acid phosphatase, AMPase and esterase. 2. besides these substances, in the surface epithelial cells was found tryptophan and in the body cells tryptophan and RNA.
