The reduction in Isc in response to hemoglobin was reversed by L-arginine and blockers of chloride secretion, including bumetanide and diphenylamine-2-carboxylic acid, but not by the potassium channel blockers, barium and tetraethylammonium, nor by amiloride, an epithelial sodium channel blocker.

In freshly isolated colonic strips, basolateral addition of ligustrazine stimulated a rise in I (SC), which was resistant to basolateral application of neuronal sodium channel blocker tetrodotoxin (TTX), but inhibited by 55.2% by basolateral pretreatment with prostaglandin inhibitor indomethacin.
The ligustrazine-induced I (SC) increase was inhibited by apical application of Cl (-) channel blockers diphenylamine-2,2'-dicarboxylic acid (DPC) and glibenclamide.

Steady-state I (SC) averaged 87.5+/-2.9 microA cm (-2) (n=185) and was reduced by 97.1+/-0.1% (n=80) by apical amiloride (100 microM) confirming that the predominant electrogenic transport across M-1 monolayers is sodium absorption via the epithelial sodium channel (ENaC).
In contrast, the response was largely reduced in the presence of apical diphenylamine-2-carboxylic acid (1 mM) and in the absence of extracellular Cl (-).

When the epithelium was pretreated for 3 min with the sodium channel blocker amiloride, the methacholine (1,000 microM)-induced J (G) increased to 0.67 +/- 0.09 microl. min (-1). cm (-2), and the hyperpolarization increased to 2.2 +/- 0.5 mV over the amiloride-pretreated level.
When pretreated for 3 min with the chloride channel blocker diphenylamine-2-carboxylic acid, the methacholine (1,000 microM)-induced J (G) was inhibited to 0.20 +/- 0.06 microl. min (-1). cm (-2), and the methacholine-induced hyperpolarization was abolished.
