Introduction

Gastric mucosa

The gastric mucosa is the mucous membrane layer of the stomach, which contains the glands and the gastric pits. The lining of the digestive tract is filled with the gastric mucosa is a work of art in terms of functional design in the mucosal membrane. It secretes an aggressive mixture of digestive fluids, powerful enough to digest any tissue, as the tissue lining the stomach. The gastrointestinal mucosa, however, is unaffected by the influence of its own defensive systems. The risk of stomach erosions and ulcers remains a stark reminder that the gastric mucosa is not always impervious to harm. Endoscopic resection procedures that are minimally invasive enable for definitive histological staging of dysplasia and early cancer, as well as curative treatment in many situations. Endoscopic mucosal resection (EMR) should be considered as a diagnostic and therapeutic first line operation in Barrett's oesophagus with High Grade Dysplasia (HGD) or early mucosal cancer, with the option of repeating the procedure if residual Barrett's dysplasia or mucosal cancer exists. Surgical resection should be considered in the early stages of submucosal carcinoma. When en bloc resection is required in big lesions, endoscopic submucosal dissection (ESD) is a helpful therapeutic option for HGD or early cancer in the squamous epithelium of the oesophagus or stomach [1].

Gastric mucosal secretion

Gastric acid secretion aids protein digestion, iron absorption, vitamin B12 absorption, and the absorption of certain medications, as well as preventing bacterial overgrowth, enteric infection, and potentially community-acquired pneumonia, spontaneous bacterial peritonitis, and IgE-mediated food allergy. It is influenced by neurological (pituitary adenylate cyclase-activating peptide), hormonal (gastrin, ghrelin, and apelin), and paracrine (histamine) pathways, as well as chemical (amino acids) and bacterial stimuli (e.g., Helicobacter pylori). Novel peptides, such as parathyroid hormone-like hormone in histamine-secreting enterochromaffin-like cells and hepcidin in acid-secreting parietal cells, have been discovered in stomach mucosal neuroendocrine cells and may have physiologic function [2].

Translocation of the proton pump, HK-ATPase, to the apical membrane, as well as activation of apical chloride and potassium channels, are required for the secretion of hydrochloric acid by parietal cells. Chromogranin A for neuroendocrine tumours, pepsinogen I for gastric atrophy, and pepsinogen II for H. pylori infection are all serum indicators [2].

Types of glands in gastric mucosa

Mucous epithelia and related glands are essential body surfaces that are topologically in direct contact with the environment and communicate with it. Several layers of defence, including as mucous gels, regeneration and repair mechanisms, and acute inflammatory processes, defend these highly specialised epithelia. Chronic inflammation is linked to cancer on a pathological level. Mucous epithelia have two separate regeneration and repair mechanisms that operate on different time scales. Within minutes, rapid repair of superficial injuries by cell migration - a process known as restitution - begins. Second, self-renewal occurs within days to months due to continual regeneration via differentiation and proliferation of stem and progenitor cells.

This article examines the molecular mechanisms underlying the regeneration of various mucosal epithelia, with a focus on the complicated situation that exists in the stomach mucosa and glands. For example, the histology, regeneration rates, and regeneration profiles of the two major types of stomach units, the fundic and antral types, differ significantly. Currently, a rough picture of the molecular mechanisms underpinning the phenomenon is emerging, which includes the characterisation of many somatic stem cell types and stem cell signalling pathways. Furthermore, dysregulated regeneration is now recognised as a contributing factor in a variety of metaplasias (reversible epithelia remodelling) and cancers, with chronic inflammation playing a significant role. [3].

Gastrointestinal absorption

The gastrointestinal absorption of paraquat (1,1'-dimethyl-4,4'-bipyridylium) was investigated utilising separated mucosa from various parts of the rat's gastrointestinal system. Tissues were stripped of their muscular layers, and the mucosa's viability was preserved in flux chambers by washing both serosal and luminal membranes with oxygenated solutions. The effects of paraquat on mucosal permeability, transmucosal potential difference (PD), and mucosal permeability were investigated. When isolated mucosae were exposed to paraquat (100 mg/ml) on the luminal side, more paraquat was absorbed across the small intestine than in other parts of the gastrointestinal tract [4].

Conclusion

As a result, it's thought that paraquat absorption in rats takes place mostly in the small intestine and is mediated by a system that includes facilitated, saturable, and diffusional components. The discovery of the method by which paraquat enters the bloodstream could lead to new techniques in the production of safer paraquat formulations.
