Myofibroblasts in schistosomal portal fibrosis of man.
Inschistosomal pipestem fibrosis myofibroblasts appear as transient cells, focally accumulated around damaged portal vein branches, and do not seem to have by themselves any important participation in the pathogenesis of hepatosplenic schistosomiasis. Expand
Pathology of the spleen in hepatosplenic schistosomiasis. Morphometric evaluation and extracellular matrix changes.
Histological, ultrastructural, morphometric and immunohistochemical data obtained from the study of spleens removed by splenectomy from 34 patients with advanced hepatosplenic schistosomiasisExpand
Analysis of spermiogenesis like a tool in the study of the triatomines of the Brasiliensis subcomplex.
This work aims to characterize this stage of spermatogenesis in triatomines little studied, and especially to compare it among the species Triatoma lenti and T. sherlocki, to assist in the diagnosis of differentiation of these insects. Expand
Interrelationship between adipocytes and fibroblasts during acute damage to the subcutaneous adipose tissue of rats: an ultrastructural study.
The present findings, in their time sequence, strongly suggest the transformation of adipocytes into fibroblasts after acute injury to adipose tissue. Expand
