Kidneys sans glomeruli.
The evolution of the vertebrate kidney records three occasions, each separated by about 50 million years, when fish have abandoned glomeruli to produce urine by tubular mechanisms. The recurring dismissal of glomeruli suggests a mechanism of aglomerular urine formation intrinsic to renal tubules. Indeed, the transepithelial secretion of organic solutes and of inorganic solutes such as sulfate, ...
متن کاملSTAG ES OF DEVELOPMENT OF RENAL GLOMERULI IN THE NEWBORN RAT KIDNEY
Glomerular development of the kidney was studied in newborn rats by electron microscopy. Four different stages of glomerular development were defined: vesicle fonnation, S-shaped body stage, capillary loop fonnation, and glomerular maturation. In the fust stage, the mesenchymal cells form a spheroid mass. This is followed by the S-shaped body stage in which clefts appear in the mass. Afte...
متن کاملProstaglandin synthesis in isolated rat kidney glomeruli.
Isolated rat kidney glomeruli converted octatritiated arachidonic acid to several prostaglandins whose production was inhibited by meclofenamate. These were, in order of decreasing abundance, prostaglandin F2 alpha, prostaglandin E2, 6-oxo-prostaglandin F1 alpha, thromboxane B2, and prostaglandin D2. These products were identified by thin-layer chromatography, before and after treatment with po...
متن کاملLight chain distribution in immune deposits on glomeruli of kidneys in human renal disease.
The gammaG-immunoglobulin (IgG) deposited on glomeruli of 32 percutaneous renal biopsies from 30 patients with various forms of renal disease was examined by fluorescent techniques to determine its light chain composition. Serum kappa: lambda light chain ratios were determined on 17 serum samples from 16 of the 30 patients. Glomerular IgG staining with only antikappa antiserum, only antilambda ...
متن کاملThe Effect of Lactobacillus Fermentum against Lead-Induced Oxidative Damages in Rat Kidneys
Background: Kidneys are the most vulnerable organs with respect to oxidative stress caused by lead poisoning. In this study, renal biomarkers were investigated in rats, exposed to lead after treatment with or without Lactobacillus fermentum. Methods: Twenty-four rats were divided into four groups of five each as follows: a) control, b) lead-exposed, c) Lactobacillus fermentum–treated, and d)...
