Microscopical Examination of Living Cells

The urinary sediment beyond light microscopical examination.

In the present issue of NDT, Chan et al. [1] report that the messenger (m) RNA expression of T-bet (a central Th1 transcription factor), interleukin (IL)-10, transforming growth factor (TGF)-b and MCP-1 in the urinary sediment of patients with active lupus nephritis decrease with successful immunosuppressive therapy. Importantly, various other cytokine mRNAs, including those of IL-2, -4, -12 an...

Scanning electron microscopical examination of gonococcal urethral exudate.

The relationship of gonococci and phagocytes in gonococcal urethral exudate was examined using a scanning electron microscope. Several stages in the phagocytic process were evident. These included pseudopodias, microvilli, and simple attachment of gonococci to phagocytic surfaces. Epithelial cells, also a part of the exudate, were examined in this study. Parallels are drawn between this and oth...

Localisation of CD10 to biliary canaliculi by immunoelectron microscopical examination.

Common acute lymphoblastic leukaemia antigen (CALLA) was first characterised in lymphoid leukaemic cells. The antigen is present in different stages of lymphoid cell differentiation as well as in subsets of myeloid cells, and further studies have also shown its presence in non-lymphoid tissues. The recent cloning and sequencing of the gene permitted deduction of its amino acid sequence which is...
