(Pathology Research and Practice, 1994-11-01) [Artigo]
Immunohistochemistry was applied to identify the nature of the nucleated cells that accumulate in the vasa rectae of the corticomedullary junction in acute tubular necrosis. In all 6 cases studied, there were intravascular ...

Pancreas transplantation versus islet transplantation versus insulin therapy in the prevention of nephropathy in alloxan-induced diabetic rats
(Transplantation Proceedings, 1998-03-01) [Artigo]
(Acta Ophthalmologica Scandinavica, 1997-06-01) [Artigo]
Keratoacanthoma is a rapidly growing skin neoplasia that may stabilize or regress spontaneously. We describe here a case of conjunctival keratoacanthoma and comment about the clinical signs and symptoms and pathological findings.
Effect of long-term treatment with insulin and/or acarbose on glomerular basement membrane thickening in alloxan-diabetic rats
(Brazilian Journal of Medical and Biological Research, 1996-10-01) [Artigo]
Acarbose is a competitive inhibitor of the intestinal alpha-glycosidases, that can delay absorption of intestinal carbohydrates causing their malabsorption. In the present paper we studied the effects of insulin, acarbose ...
DELAYED-TYPE HYPERSENSITIVITY RESPONSE IN AN ISOGENIC MURINE MODEL OF PARACOCCIDIOIDOMYCOSIS
