ESR: erythrocyte sedimentation rate INTRODUCTION Rosai-Dorfman disease, also called sinus histiocytosis with massive lymphadenopathy, is a rare histiocytic condition of unknown etiology first described in 1969. Primary cutaneous manifestation without systemic involvement of Rosai-Dorfman disease is even more uncommon. Here we present a case of primary cutaneous manifestation of Rosai-Dorfman di...

Sedimentation dynamics in the East China Sea was investigated based on profiles and inventories of Pb , Cs and ex Pu in sediment cores collected from various settings in this marginal sea. The derived sedimentation rates vary by two orders of magnitude, from ;2 to 0.02 cm yr, and generally decrease southward along the inner shelf and eastward offshore. This pattern is consistent with the disper...

In the ultracentrifuge, normal human serum shows, in addition to the lipoproteins, three distinct components with sedimentation rates of approximately 4, 7, and 19 Svedberg units (1, 2). Other materials known to be present are obscured by the high concentrations of these major substances and the high diffusion spreading of the boundaries. For example, Edsall (3) has reported a number of additio...

A study of the erythrocyte sedimentation rate during the first hour (ESR) in dengue patients would help determine how this parameter is affected by this disease, as well as whether it can be used for diagnosis. One thousand, three hundred and ninety-eight cases of dengue attended at the Dengue Treatment Center, Campos dos Goytacazes Rio de Janeiro, Brazil, were included. The ESR values were cla...

Primary human lung fibroblasts were separated into small ( group I), intermediate ( group II), and large ( group III) subpopulations by unit gravity sedimentation (1 G). The three subsets retained differences in cell size for up to 15 days of primary culture. Flow cytometric (fluorescence-activated cell sorter) measurements of forward-angle light scatter agreed well with fibroblast volume measu...

A procedure is described which permits the isolation from the prepuberal mouse testis of highly purified populations of primitive type A spermatogonia, type A spermatogonia, type B spermatogonia, preleptotene primary spermatocytes, leptotene and zygotene primary spermatocytes, pachytene primary spermatocytes and Sertoli cells. The successful isolation of these prepuberal cell types was accompli...
