    Notes: Abstract  Crescentic glomerulonephritis leads to a rapid loss of renal function. Although glomerular crescents are rich in extracellular matrix (ECM), the composition and genesis of the ECM are incompletely understood. Heparan sulfate (HS) is a major ECM molecule and has polymeric structure of great variability. Recent findings that alterations in HS epitopes are associated with renal pathology prompted us to hypothesize that specific HS epitopes might be expressed in the evolution of crescents. We reviewed clinical records of 724 patients who underwent renal biopsy and found 21 patients with rapidly progressive glomerulonephritis. Immunohistochemistry was performed using monoclonal antibodies (mAbs) against well-defined HS epitopes. One mAb was directed against unsaturated uronic acid residues generated during the selective removal of HS by heparitinase (a), and a further two different mAbs against N-sulfate-enriched and O-sulfate-poor portions of HS (b). Results showed that mAb (a) reacted to ECM of normal, sclerosed and crescentic glomeruli and that mAbs (b) reacted strongly to ECM of fibrocellular crescents but not to fibrous crescents, the periglomerular areas and noncrescentic intraglomerular areas. We concluded there are regional differences in HS epitope expression, although HS are ubiquitous components of glomerular ECM. N-sulfate-enriched and O-sulfate-poor portions of HS might play a role in crescent formation.

    Age-dependence of the lateral diffusion coefficient of Concanavalin-A receptors in the plasma membrane of ex vivo prepared brain cortical nerve cells of BN/BiRijHsd rats (1999)

    Notes: Abstract  A new method has been developed for ex vivo preparation of brain cortical cells of BN/BiRijHsd rats to make them suitable for the measurement of the lateral diffusion coefficient of the membrane components by means of fluorescence recovery after photobleaching (FRAP). The method involves chopping the brain cortex into pieces of less than 1 mm. These parts are stained with a fluorescent label (e.g., concanavalin-A-fluorescein, Con-A-FL conjugate) and then gently pressed onto a microscope slide using the coverslip. In the resulting specimen, the largest cells of the cortex can be recognized in phase-contrast image, sufficiently stained by the label and ready for the FRAP measurement. The lateral diffusion coefficient of Con-A-receptor proteins (D p) was measured in such brain cell preparations of 15 female rats in four age groups (5.6–31.8 months) and 11 males in three age groups (13.8–31.8 months). Highly significant negative, linear age correlation of D p (R=−0.9958 in females, and −0.9956 in males) were found, the regression equations being D p,=(8.8311–0.1425 X)−10 and D p█=(9.3240−0.1630 X)−10 cm2/s, respectively, where X is age in months. The data confirm that the lateral mobility of plasma membrane proteins represents an important biomarker of cellular aging in the brain cortical cells of BN/BiRijHsd rats.

    Lung uptake of technetium-99m microaggregated human albumin in the rat after treatment with microaggregated human albumin or macroaggregated human albumin (1978)

    Notes: Abstract Marked accumulation in lung and liver of intravenously-injected 99mTc-microaggregated human serum albumin (liver imaging agent) was observed in rats pretreated with the subcutaneous injection of microaggregated or macroaggregated human serum albumin, whereas accumulation of 99mTc-microaggregated human serum albumin was observed only in the liver of rats pretreated with plain human serum albumin or in non-treated control rats. The activity of the intravenously-administered 99mTc-sulfur colloid was concentrated in the liver and spleen only and not in the lung, of rats previously treated with human serum albumin, microaggregated human serum albumin, or macroaggregated human serum albumin. These observations suggest that the specific accumulation of microaggregated human serum albumin in the lung of rats pretreated with aggregated albumin is due to rapid in vivo clumping of injected particles, possibly due to antigen-antibody reaction.
