hydrogen sulfide (h2s) has been shown to protect the gastric mucosa through several protective mechanisms but till now its effect on mrna expression of sodium bicarbonate cotransporter 1 (nbc1), trefoil factor1 (tff1) and trefoil factor2 (tff2) was not investigated. this study was aimed to evaluate the effect of h2s on mrna expression of nbc1, tff1 and tff2 in rat gastric mucosa in response to ...
Extract of gazyagi has protective effect against ethanol-induced gastric ulcer and it decreases microscopical ulcer index in rat. At the last some years, treatment of peptic ulcer by medicinal herbs have been were very successful. Gazayagi (Falcaria vulgaris) is a member of Umbelliferae family. In the folk medicines of the west of country, this herb is used for healing of skin ulcer and peptic ...
Trypanosoma cruzi is an intracellular parasite transmitted from a reduviid insect vector to humans by exposure of mucosal surfaces to infected insect excreta. We have used an oral challenge murine model that mimics vector-borne transmission to study T. cruzi mucosal infection. Although gastric secretions have microbicidal activity against most infectious pathogens, we demonstrate that T. cruzi ...
The gastric mucosa is continuously exposed to many noxious factors and substances. How the gastric mucosa maintains structural integrity and resists auto-digestion by substances such as acid and pepsin puzzled clinicians and investigators for more than 200 years. The gastric epithelium must also resist damage from extrinsic agents, including Helicobacter pylori (H. pylori) and noxious ingestion...
Turmeric (from Zingiberaceae family) is highly regarded as a universal panacea in the herbal medicine with wide spectrum of pharmacological activities. Forty eight adult rats (150g-200g body weight) were randomly divided into six (control, treatment, 3 post treatment and recovery) groups each. Gastric injury induced administration different concentration Aspirin co treated for period 14-28 days...
The study was to investigate the protective effect of total flavonoid from Ba lotus leaf (BLLF) on reserpine (10 mg/kg)-induced gastric ulcer in KM (Kunming) mice. BLLF was given by gavage in mice, the serum and gastric tissue levels of MOT, SP, VIP, SS, SOD (T-SOD), GSH-Px and MDA were tested by experiment kits, the cytokine levels of TNF-α, IFN-γ, IL-6, and IL-12 were also checked by kits. Th...
The inhibitory effect of an anti-ulcer drug irsogladine [2,4-diamino-6-(2,5-dichlorophenyl)-s-triazine maleate] on monochloramine (NH(2)Cl)-induced gastric mucosal lesions and its mechanisms of action were clarified in rats. Irsogladine dose-dependently prevented the formation of gastric mucosal lesions induced by 60 mM NH(2)Cl. The mucosal protective effect of irsogladine was not influenced by...
Our objective was to investigate the protective effect of Lawesson's reagent, an H2S donor, against alendronate (ALD)-induced gastric damage in rats. Rats were pretreated with saline or Lawesson's reagent (3, 9, or 27 µmol/kg, po) once daily for 4 days. After 30 min, gastric damage was induced by ALD (30 mg/kg) administration by gavage. On the last day of treatment, the animals were killed 4 h ...
This research was performed in order to determine the potential protective effects of ozonized sunflower oil (OSO) in the injury of rat gastric mucosa induced by absolute ethanol and as well as to elucidate the role of reactive oxygen species (ROS), lipid peroxidation, and some important constituents of antioxidant defense such as superoxide dismutase (SOD), glutathione peroxidase (GSH-Px), and...
Epidermal growth factor (EGF) has been shown to exert gastric hyperemic and gastroprotective effects via capsaicin-sensitive afferent neurons, including the release of calcitonin gene-related peptide (CGRP). We examined the protective and vasodilatory effects of EGF on the gastric mucosa and its interaction with sensory nerves, CGRP, and nitric oxide (NO) in anesthetized rats. Intragastric EGF ...
