Topical application of benzalkonium chloride to the stomach serosa increases gastric emptying time, acid secretion, serum gastrin and size of the mucosa

Abstract: The absence of the myenteric plexus seems to protect the stomach from the hyperplastic effects of hypergastrinemia. Gastric food stasis may act as a factor triggering morphological and functional alterations of the gastric epithelium. Although gastric food stasis is a common finding in medical practice, its physiopathological consequences are poorly understood and have not been frequently discussed in the literature.

“…Interestingly, these changes did not occur when denervation was combined with pyloroplasty, indicating that, after denervation, gastric distension and stasis are the major stimuli for hyperplasia [34]. The role of gastric food stasis as a major factor triggering morphological alterations of the gastric epithelium has been reinforced by the observation that the BAC-denervation of the rat stomach increases gastric emptying time, acid, and the gastrin secretion together with the increase of the size of the mucosa [35].…”

“…It is known that BAK has a neurotoxic effect in smooth muscle and has thus been used to create models of myenteric denervation. [10][11][12][13][14][15][16][17] This neurotoxic effect has not been studied in skeletal muscle such as the OOM.…”

“…Essa substância foi descrita primeiramente no ano de 1950 como "um agente desinfetante para a pele" (Price, 1950 (Sakata et al, 1979). Esse modelo de desnervação foi testado também em outros locais do trato gastrointestinal, como no íleo (Garcia et al, 1995) no esôfago (Febrônio et al, 1997), no jejuno (Zucoloto et al, 1988;Carvalho et al, 2006), no estômago (Sobreira et al, 2002;Polli-Lopes et al, 2003;Zucoloto et al, 2002) e como um modelo utilizado para aumento da superfície absortiva intestinal na síndrome do intestino curto (Garcia et al, 1999). O BAC é uma substância seletiva para neurônios mientéricos.…”

“…Estudos experimentais com animais indicaram também o mesmo resultado apresentado no estudo clínico (Garcia et al, 1996;Vespúcio et al, 2008). Ainda, achados similares foram encontrados no estômago (Sobreira et al, 2002;Zucoloto et al, 2002;Polli-Lopes et al, 2003). Nesse sentido, embora esteja claro que exista o fenômeno de proteção contra o câncer ocasionado pela desnervação, ainda não existem estudos que abordem os mecanismos pelos quais isso ocorra.…”
