Unlabelled: The aim of the study was to examine dynamics of the content of nitric oxide (NO) in gastric juice in Helicobacter-associated gastroduodenal diseases.
Materials And Methods: 105 patients were examined: 56 - with chronic non-atrophic (antral) gastritis (CNG) and 49 - duodenal ulcer (DU). 25 healthy individuals were studied as control.
Results: It was found that NO concentration increases in gastric juice at the exacerbation of CNG and DU. Moreover, in patients with CNG with the elimination of Helicobacter pylori and inflammatory activity in the gastric mucosa, NO levels decrease to control values, and in DU patients in remission phase the level of it is markedly reducing, but remains higher than normal. The NO content changes, depending not only on a phase, but also character of a course of a disease, are observed at patients with Duodenal ulcer. At recurrent course UD index of NO in the gastric juice was significantly higher than in newly diagnosed destructive process in the mucosa.
Conclusion: The carried out research show that H. pylori infection stimulates the metabolism of NO in the gastric CO. The Increase in the levels of NO can be regarded as a protective reaction in response to the persistence of HP.

Acute alcohol intoxication could cause multiorgan damage, including nervous, digestive, and cardiovascular systems, and in particular, irreversible damage to the brain and liver. Emerging studies have revealed that the endogenous multienzymatic antioxidant defense system (MEAODS) plays a central role in preventing oxidative stress and other toxicological compounds produced by alcohol. However, few available drugs could quickly regulate MEAODS.

Betel quid contains two major ingredients; Areca catechu and Piper betel, often consumed with slaked lime, tobacco, certain flavouring agents, colouring agents, herbs, and spices according to personal preferences. The areca nut alkaloids (arecoline, arecaidine, guvacine, and guvacoline), and tobacco alkaloids (nicotine, nor-nicotine) undergo nitrosation during chewing in the oral cavity with the presence of nitrite and thiocyanate and endogenously. Among the nitrosation products generated areca nut-derived nitrosamine (ADNA): 3-(methylnitrosamino) Propionitrile (MNPN) and the two tobacco-specific nitrosamines (TSNAs); N'-nitrosonornicotine (NNN) and 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone) (NNK) are considered Group 1 human carcinogens.

Inflammatory bowel disease (IBD) is a chronic inflammation with a high incidence rate. Many probiotics, including (), have shown promise in IBD treatment. The therapeutic effects of most probiotics are greatly decided by the available live cells in the disease lesion, which is compromised as they pass through the gastric juice and intestinal tract, resulting in a loss of activity.

Gastroretentive systems have gained attention due to their prolonged retention time in the human body, and they have the potential to improve treatment effects, simplify treatment regimens, and improve patient compliance. Among these systems, expandable gastroretentive systems (EGRSs) have emerged as an important type of carrier that can reside in the stomach for a desired period through on-demand expansion for drug delivery, obesity intervention, and medical diagnosis. As the physiological environment significantly influences the performance of EGRSs, here, the physiological factors such as the stomach's physiological structure and activity pattern, and the character of gastric juice are summarized.

Background/aims: Psoriasis is a common inflammatory skin disorder following non-specific triggers. Involvement of immune system is widely accepted for pathogenesis studies have demonstrated importance of gut microbiota in pathogenesis of inflammatory skin diseases. Proton pump inhibitor (PPI) and histamine-2 receptor antagonist (H2RA) are acid-suppressive drugs widely used for acid related gastrointestinal diseases, and prolonged use has been associated with altered gut microbiota.
