Název v původním jazyce

Transepithelial potential in mesonephric nephrons of 7-day-old chick embryos in relation to the histochemically detected sodium pump.

Popis výsledku v původním jazyce

Measurements of transepithelial potential difference (TPD) in individual segments of superficial nephrons in vivo revealed there the electrogenic transport. Their electric polarity was always lumen-negative. TPD was reduced by addition of 10 mM KCN to the nephrons from outside. Between proximal and distal tubules there was found a significant difference in TPD (-0.1 0.5 mV and ů2.2 1.0 mV, resp.) that corresponded to distribution of the histochemically detected sodium pump along the nephrons. The pump represented by the activity of K+-NPPase was demonstrated in the distal nephron segments exclusively. It is concluded that it is only the distal nephron, which possesses the ability of active transport.
