Studies on the Electrical Potential Profile across Rabbit Ileum
When isolated strips of mucosal rabbit ileum are bathed by physiological electrolyte solution the electrical potential difference (PD) across the brush border (psi(mc)) averages 36 mv, cell interior negative. Rapid replacement of Na in the mucosal solution with less permeant cations, Tris or choline, results in an immediate hyperpolarization of psi(mc). Conversely, replacement of choline in the...
متن کاملElectrical potential profile in rabbit ileum: role of rheogenic Na transport.
The electrical potential profile of rabbit ileum was investigated in vitro with the microelectrode technique. The transmural electrical potential difference (PD), designated psims, was immediately reduced by 60% upon cooling the tissue from 37 to 7 degrees C; the PD across the mucosal membrane (transmucosal PD, psimc) was simultaneously reduced by 37%. These electrical changes could not be attr...
متن کاملElectrical potential differences across the foetal membranes of the rabbit.
T H E chemical composition of the foetal fluids in the rabbit was studied by Davies & Routh (1957). These investigators showed that the amniotic and exocoelomic fluids resembled extracellular fluid in their ionic composition whereas the allantoic fluid more closely resembled intracellular fluid. These findings were confirmed by Dickerson & McCance (1957). An experimental study of the trans-memb...
متن کاملLysine Transport across Isolated Rabbit Ileum
Lysine transport by in vitro distal rabbit ileum has been investigated by determining (a) transmural fluxes across short-circuited segments of the tissue; (b) accumulation by mucosal strips; and (c) influx from the mucosal solution across the brush border into the epithelium. Net transmural flux of lysine is considerably smaller than that of alanine. However, lysine influx across the brush bord...
متن کاملAlanine and Sodium Fluxes Across Mucosal Border of Rabbit Ileum
Unidirectional influxes of L-alanine and Na from the mucosal solution into the epithelium of in vitro rabbit ileum have been determined. In the presence of 140 mM Na, alanine influx is approximately 2.2 micromoles/hr cm(2), but is inhibited if the NaCl in the mucosal solution is replaced by choline Cl, Tris-Cl, mannitol, LiCl, or KCl. Although alanine influx is strongly dependent upon Na in the...
