Total 4-hydroxyproline content and volume were measured in the same sample of microdissected glomeruli obtained fro rat and human outer or inner cortex. Glomerular volume was determined by computer-assisted image analysis, and 4-hydroxyproline was measured by a highly sensitive gas-liquid chromatographic method. Results were expressed as weight of basement membrane material by comparison with t...
