The effects of bradykinin (BK) and histamine on transepithelial ion transport in primary cultures of gerbil middle ear epithelium were investigated.
Diphenylamine-2-carboxylate or 4,4'-diisothiocyanostilbene-2,2'-disulfonic acid, Cl- channel blockers, significantly blocked the I (sc) responses to lys-BK or histamine.

The potency sequence for stimulation of Isc by mediators was methacholine greater than bradykinin greater than isoproterenol approximately or equal to phenylephrine.
Diphenylamine-2-carboxylic acid, however, had no effect on baseline Isc but markedly inhibited the Isc response to all mediators.

Isoproterenol (a modulator of cAMP-activated chloride channels) increased the exchange rate by a factor of 1.4+/-0.1; A23187 (a modulator of calcium-activated chloride channels) increased the rate by 3.4+/-0.4; bradykinin (also a modulator of calcium-activated chloride channels) increased the rate by 2.0+/-0.4; forskolin (a direct stimulator of adenylate cyclase) increased the rate by 2.7+/-0.3.
Diphenylamine-2-carboxylate (a chloride channel blocker) decreased the rate by 0.12+/-0.03.

The current could be inhibited by apical application of the chloride channel blocker, diphenylamine-2-carboxylate.
In contrast to bradykinin, angiotensin II and endothelin I, the effect of CGRP was independent of prostaglandin synthesis.

The increase in SCC by AII was dependent upon extracellular Cl- and was inhibited by addition of a Cl- channel blocker, diphenylamine 2-carboxylate, to the apical surface.

Apical Cl transport was sensitive to diphenylamine-2-carboxylate (DPC) but not to furosemide, whereas basolateral membrane Cl transport was sensitive to furosemide but not to DPC.
