AIMS To review the histological features of lymph nodes excised from seven patients with rheumatoid arthritis and one with systemic sclerosis. METHODS Lymph nodes excised from seven patients with rheumatoid arthritis and one patient with systemic sclerosis over a 10 year period were examined using the stains haematoxylin and eosin, periodic acid Schiff (PAS), Masson-trichrome, and Congo red f...

Two new ectocarpic arbuscular mycorrhizal fungal species, Glomus drummondii and G. walkeri (Glomeromycota), found in maritime sand dunes of northern Poland and those adjacent to the Mediterranean Sea are described and illustrated. Mature spores of G. drummondii are pastel yellow to maize yellow, globose to subglobose, (58-)71(-85) micromdiam, or ovoid, 50-80x63-98 microm. Their wall consists of...

BACKGROUND Lymphoproliferative disorders causing paraproteinemia can be associated with various kidney injuries including the deposition of monoclonal immunoglobulins (Ig). A known glomerular manifestation of Waldenström's macroglobulinemia is characterized by prominent intracapillary hyaline thrombi and lack of conspicuous glomerular proliferation. The present case was special in 2 aspects: 1....

Wide tissue septa and dilated lymphatics can be seen in histological sections from the lungs of infants dying from hyaline membrane disease (Wade-Evans, 1962; Balis, Delivoria, and Conen, 1966). These might be produced either by the excessive transfer of liquid from the plasma to the lung interstices, or by the defective clearance of the liquid which normally fills the potential airspaces of th...
