After benzalkonium chloride treatment, there was significant delay in gastric emptying of liquids and an increase in mucosal area of all gastric portions, in antral mucosal volume, in parietal cell area, and gastrin-G cell and somatostatin-D cell populations.

The myenteric plexus of a segment of rat jejunum was destroyed by serosal application of benzalkonium chloride (BAC).
Fifteen days after BAC treatment, both the BAC-treated and an orad control jejunal segment were removed and the mechanical responses of the longitudinal muscle produced by the following substances were examined: substance P, acetylcholine (ACh), 5-hydroxytryptamine (5-HT), cholecystokinin octapeptide (CCK-8), norepinephrine, vasoactive intestinal peptide (VIP), bombesin, [Leu5] enkephalin and somatostatin.

We have examined the relative importance of luminal and neuronal mechanisms, by lesioning the antral innervation using benzalkonium chloride. 2.
Plasma gastrin was measured by radioimmunoassay and mRNAs encoding gastrin, somatostatin and histidine decarboxylase were measured by Northern blot. 3.

The release of histamine induced by these neuropeptides was inhibited by preincubation of the cells with the SP analogue [D-Pro4,D-Trp7,9,10]-SP4-11 (SP-A) (10 microM), and also by benzalkonium chloride (10 microM).

These changes are probably induced by functional imbalance by the surviving neuronal elements in the gut, implicating neurotransmitters such as acetylcholine, noradrenaline, serotonin, somatostatin and vasoactive intestinal peptide.
The duodenum or descending colon of male Wistar rats (average weight 60 g) was treated by a serosal application of a 0.2% solution of benzalkonium chloride (BAC) for 30 min.

Various concentrations of the cationic surfactants benzalkonium chloride (BAC) and benzethonium chloride, the anionic surfactants sodium ricinoleate, dioctyl sodium sulfosuccinate and sodium lauryl sulfate and the nonionic surfactant Triton X-100 were applied to the serosal surface of the rat jejunum every 5 min for 0.5 hr and then rinsed off with saline.
BAC treatment markedly reduced the immunoreactivity of somatostatin, substance P, met-enkephalin and vasoactive intestinal peptide in the myenteric plexus.
