Interaction between endogenous carbon monoxide and hydrogen sulfide in the mechanism of gastroprotection against acute aspirin-induced gastric damage. Pharmacol Res 2016; 114:235-250. [PMID: 27825819 DOI: 10.1016/j.phrs.2016.11.001] [Citation(s) in RCA: 40] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/31/2016] [Revised: 09/12/2016] [Accepted: 11/02/2016] [Indexed: 02/07/2023]
Abstract
Acetylsalicylic acid (ASA) is mainly recognized as painkiller or anti-inflammatory drug. However, ASA causes serious side effects towards gastrointestinal (GI) tract which limits its usefulness. Carbon monoxide (CO) and hydrogen sulfide (H2S) have been described to act as important endogenous messengers and mediators of gastroprotection but whether they can interact in gastroprotection against acute ASA-induced gastric damage remains unknown. In this study male Wistar rats were pretreated with 1) vehicle (saline, i.g.), 2) tricarbonyldichlororuthenium (II) dimer (CORM-2, 5mg/kg i.g.), 3) sodium hydrosulfide (NaHS, 5mg/kg i.g.), 4) zinc protoporphyrin (ZnPP, 10mg/kg i.p.), 5) D,L-propargylglycine (PAG, 30mg/kg i.g.), 6) ZnPP combined with NaHS, 7) PAG combined with CORM-2 or 8) 1H-[1,2,4]oxadiazolo[4,3-a]quinoxalin-1-one (ODQ, 10mg/kg i.p.) combined with CORM-2 or NaHS and 30min later ASA was administered i.g. in a single dose of 125mg/kg. After 1h, gastric blood flow (GBF) was determined by H2 gas clearance technique and gastric lesions were assessed by planimetry and histology. CO content in gastric mucosa and COHb concentration in blood were determined by gas chromatography and H2S production was assessed in gastric mucosa using methylene blue method. Protein and/or mRNA expression for cystathionine-γ-lyase (CSE), cystathionine-β-synthase (CBS), 3-mercaptopyruvate sulfurtransferase (3-MST), heme oxygenase (HO)-1, HO-2, hypoxia inducible factor-alpha (HIF)-1α, nuclear factor (erythroid-derived 2)-like 2 (Nrf-2), cyclooxygenase (COX)-1 and COX-2, inducible nitric oxide synthase (iNOS) and interleukin (IL)-1β were determined by Western blot or real-time PCR, respectively. ASA caused hemorrhagic gastric mucosal damage and significantly decreased GBF, H2S production, CO content, mRNA or protein expression for CSE, 3-MST, HO-2 and increased mRNA and/or protein expression for CBS, HO-1, Nrf-2, HIF-1α, iNOS, IL-1β, COX-2 in gastric mucosa and COHb concentration in blood. Pretreatment with CORM-2 or NaHS but not with PAG decreased ASA-damage and increased GBF. ZnPP reversed protective and hyperemic effect of NaHS but PAG failed to affect CORM-2-induced gastroprotection. CORM-2 elevated CO content, mRNA or protein expression for HO-1, Nrf-2, and decreased expression of CBS, HIF-1α, COX-2, IL-1β, iNOS, the H2S production in gastric mucosa and COHb concentration in blood. NaHS raised mRNA or protein expression for CSE, COX-1 and decreased mRNA expression for IL-1β and COHb level in blood. We conclude that CO is involved in gastroprotection induced by H2S while beneficial protective action of CO released from CORM-2 in gastric mucosa seems to be H2S-independent. In contrast to H2S, CO ameliorates hypoxia, regulates Nrf-2 expression but similarly to H2S acts on sGC-dependent manner to restore gastric microcirculation and exhibit anti-inflammatory activity in gastric mucosa compromised by ASA.

Abstract
The effect of Rhinax on gastric damage in different animal models including gastric ulceration induced by a necrotic agent such as 0.6 N HCl, indomethacin, and intragastric distension was studied. Treatment with Rhinax at a dose of 160 mg/kg protected gastric mucosa against the damage induced by oral administration of indomethacin and intragastric distension. The volume and acidity of gastric juice in pyloric ligated rats was reduced by Rhinax. It also significantly promoted gastric mucus secretion in normal animals. On the basis of these observations, we conclude that Rhinax possesses anti-ulcer activity and that the observed activity may be due to the modulation of defensive factors by improvement in gastric cytoprotection.

Abstract
YM638 ([[5-[[3-(4-acetyl-3-hydroxy-2-propylphenoxy)propyl] thio]-1,3,4-thiadiazol-2-yl]thio] acetic acid) is a novel leukotriene D4 receptor antagonist. We investigated the involvement of the leukotriene D4 receptor blocking activity of YM638 in the gastric mucosal protection of this drug in rats. YM638 significantly prevented gastric lesion formation induced by water-immersion restraint stress, indomethacin, absolute ethanol, 0.7 N HCl and the combination of 0.2 N HCl and hemorrhagic shock, with ED50 values of 26.4, 4.1, 4.7, 35.4 and 8.0 mg/kg p.o., respectively. Cetraxate and sofalcone showed inhibitory effects on most of these gastric lesions, but the inhibitory effects of these compounds were much weaker than those of YM638. In contrast, YM638 had no effect on gastric acid secretion and gastric lesion formation in pylorus-ligated rats, or on duodenal lesion formation in cysteamine-administered rats. YM638 competitively antagonized leukotriene D4-induced contraction of the isolated stomach, with a pA2 value of 7.63 +/- 0.18. In anesthetized rats, intravenous YM638 inhibited leukotriene D4-induced aggravation of gastric lesions caused by HCl, and leukotriene D4 and HCl-induced reduction of the potential difference. In addition, oral YM638 significantly increased gastric mucosal blood flow and prevented ethanol-induced increase in gastric vascular permeability. Endogenous prostaglandins, sulfhydryls and nitric oxides were not involved in this inhibitory effect on absolute ethanol-induced gastric lesion. YM638 did not react with the stable free radical 1,1-diphenyl-2-picrylhydrazyl in vitro, indicating that YM638 does not have potential as free radical scavenger. These results suggest that the preventive effect of YM638 on gastric lesions is attributable not only to its leukotriene D4 receptor blocking activity but also to the activation of gastric mucosal defensive mechanisms such as mucosal blood flow and vascular permeability.

Abstract
We examined the effects of FK506, an immunosuppressive agent, on the genesis of water immersion stress-induced gastric lesions in rats. Using high-performance liquid chromatography, four kinds of prostaglandins, ie, 6-keto-prostaglandin F1 alpha, prostaglandin F2 alpha, prostaglandin E2, and prostaglandin D2, were detected, and no leukotrienes were detected in gastric mucosa in rats without stress. After 6 hr of stress, gastric lesions developed with decreases in all prostaglandin contents, and the emergence of peptide leukotrienes was observed. Intramuscular administration of FK506 (0.1, 0.25, 0.5, 1.0, and 2.0 mg/kg) reduced lesion index dose-dependently. Administration of FK506 at doses over 0.25 mg/kg decreased all prostaglandin contents, but did not affect the increase in leukotriene contents. Pretreatment with famotidine or omeprazole reduced lesion index, and the protective effects were equivalent to those of 1.0 mg/kg of FK506, although FK506 did not affect gastric secretion during water-immersion stress. Water-immersion stress did not change the activities of xanthine oxidase in either stomach or serum. Polyoxyethylene-modified superoxide dismutase did not prevent gastric lesions. Water-immersion stress significantly increased myeloperoxidase activity in gastric mucosa, and FK506 reduced the increase in myeloperoxidase activity induced by stress. From our results, other factors besides gastric acid secretion and tissue eicosanoid contents, such as chemoattractant factor, might also be involved in the genesis of water-immersion stress-induced gastric lesions in rats.

Abstract
We evaluated the inhibitory effect of DS-4574, a peptidoleukotriene antagonist with mast cell stabilizing action, on rat gastric mucosal lesions induced by compound 48/80 (C48/80: a mast cell degranulator), in comparison with those of disodium cromoglycate (DSCG: a mast cell stabilizer), LY171883 (a peptidoleukotriene antagonist) and cimetidine (a histamine H2 receptor antagonist). Subcutaneous administration of C48/80 (1 mg/kg) once daily for four consecutive days produced extensive gastric lesions in the fundic mucosa. DS-4574 (20, 50 and 100 mg/kg/day, oral) and DSCG (200 mg/kg/day, intraperitoneal) treatment markedly inhibited formation of these mucosal lesions, but LY171883 (100 and 200 mg/kg/day, oral) and cimetidine (400 mg/kg/day, oral) treatment did not. Moreover, DS-4574 and DSCG significantly suppressed both hyperhistaminemia and histamine release from rat peritoneal mast cells induced by C48/80. These results indicate that the inhibitory effect of DS-4574 on gastric lesions induced by C48/80 may be related to its mast cell stabilizing action, but to neither its antisecretory nor its peptidoleukotriene antagonistic activity.

Abstract
This study was designed to determine the cytoprotective properties of naringenin and the involvement of endogenous prostaglandins on mucosal injury produced by absolute ethanol. Gastric glands were also histologically analysed. Oral pretreatment with the highest dose of naringenin (200 mg kg-1), 240 min before absolute ethanol, was the most effective in ulcer prevention. Subcutaneous administration of indomethacin (10 mg kg-1) to the animals treated with naringenin (200 mg kg-1) partially inhibited the gastric protection but there was no increase in prostaglandin E2. All treated groups showed a marked increase in gastric mucus, although this increase was less in animals pretreated with indomethacin. Total proteins and hexosamine content decreased in the groups receiving indomethacin. Histomorphometric evaluation of the gastric damage, with the highest dose of naringenin (200 mg kg-1), confirmed a significant increase of mucus production accompanied by a parallel reduction of gastric lesion.

Abstract
DS-4574 is a peptidoleukotriene antagonist with mast cell stabilizing activity. In the present study, we studied the effects of this compound on gastric secretion and various acute gastric lesions in rats. Intraduodenal administration of DS-4574 at doses of 5 to 10 mg/kg significantly and dose-dependently inhibited gastric acid secretion in pylorus-ligated rats, but a further increase in the dose up to 50 mg/kg did not cause any further inhibition. Shay ulceration in response to pylorus ligation was dose-dependently prevented by DS-4574 (10-25 mg/kg, i.d.). Water-immersion restraint stress- and aspirin-induced gastric ulcers were also significantly prevented in a dose-related manner by oral pretreatment with DS-4574 (10-50 mg/kg). The lower doses of DS-4574 (1-10 mg/kg, p.o.) significantly and dose-dependently protected the gastric mucosa against the necrotizing action of either absolute ethanol or concentrated hydrochloric acid, indicating that this compound possesses a potent gastroprotective activity. These antiulcer and gastric protective effects of DS-4574 were more potent than those of cimetidine used as a reference drug. These findings suggest that DS-4574 is useful for peptic ulcer therapy, as well as for the therapy of various allergic diseases, including asthma.

Abstract
The present study was designed to determine the role of leukotrienes in aspirin-induced acute gastric mucosal injury in rats. We examined the effects of aspirin, indomethacin, and sodium salicylate on gastric mucosal injury, and on eicosanoid synthesis and content. Aspirin, indomethacin, and acidified salicylate caused significant mucosal injury, while salicylate at pH 7 did not induce significant injury. Aspirin and indomethacin significantly reduced mucosal prostaglandin synthesis and content. No significant changes in mucosal leukotriene C4 synthesis and content were observed. There were no correlations between changes in mucosal leukotriene B4 synthesis and the extent of mucosal injury. We also evaluated the effects of MK-571 (a leukotriene D4 receptor antagonist) and MK-886 (a leukotriene biosynthesis inhibitor) on aspirin-induced gastric mucosal injury. Neither MK-571 nor MK-886 could reduce the mucosal lesions induced by aspirin. These findings suggest that leukotrienes are not involved in aspirin-induced acute gastric mucosal injury in rats.

Abstract
The role of leukotrienes in the pathogenesis of acute gastric ulceration induced by nonsteroidal antiinflammatory drugs was investigated using a rat model. One part of the study involved oral pretreatment with a leukotriene synthesis inhibitor 1 h prior to administration of indomethacin (20 mg/kg per os). Three hours after indomethacin, the extent of macroscopically visible gastric damage was determined, and gastric LTB4 synthesis was determined. The compounds tested were PF-5901, A-64077, nordihydroguaiaretic acid, and L-698,037. Each compound produced dose-related inhibition of gastric LTB4 synthesis and a parallel reduction in the severity of indomethacin-induced damage. The antioxidant properties of these compounds was assessed using an in vitro assay. There was no correlation between the antioxidant properties of the compounds and their ability to reduce the severity of indomethacin-induced gastric damage. In the second part of the study, the effects of intravenous, administration of LTD4 and LTB4 receptor antagonists on indomethacin-induced gastric epithelial damage (measured by permeability to [51Cr]EDTA) were assessed. The two LTD4 receptor antagonists (MK-571 and ICI-204,219) significantly reduced the permeability changes induced by indomethacin, while the two LTB4 antagonists (SC-41930 and LY-255,283) were without significant effect. Despite the reduction of gastric epithelial injury, blockade of LTD4 receptors did not markedly affect the extent of macroscopically visible injury. These data are consistent with the hypothesis that leukotrienes contribute to the epithelial injury and macroscopically visible damage induced by NSAIDs. However, it remains unclear to what extent leukotrienes are involved in the initiation of the injury, as opposed to its amplification.

Abstract
1. This study was designed to determine whether or not endogenous prostaglandins (PG) contribute to the healing of gastric ulcers induced by high concentrations of ethanol or water immersion stress. 2. Ethanol-induced gastric lesions; rats were divided into four groups: (1) the control group: untreated; (2) the indomethacin group: indomethacin (2 mg/kg) was injected intramuscularly (i.m.) once daily until the end of the experiment; (3) the ethanol group: rats were given 1 mL of 50% ethanol intragastrically; (4) the ethanol + indomethacin group: indomethacin (2 mg/kg) was injected (i.m.) once daily from 1 h after administration of 50% ethanol until the end of the experiment. 3. Water immersion stress-induced gastric lesions; rats were divided into three groups: (1) control group: untreated; (2) stress group: rats were placed in a stress cage and immersed into a water bath (23 degrees C) for 6 h; (3) stress + indomethacin group: indomethacin (2 mg/kg) was injected (i.m.) once daily for 3 consecutive days immediately after stress treatment or from 3 days after stress treatment until the end of the experiment. 4. Immediately after observation of the lesions, the fundic mucosal layer was separated from the muscle layer and mucosal PG levels were measured by high performance liquid chromatography in each group. 5. Indomethacin did not inhibit ulcer healing until 48 h after administration in the ethanol experiment, and until 3 days after administration in the water immersion experiment. In contrast, indomethacin inhibited ulcer healing thereafter in each experiment respectively. 6. Four kinds of PG, that is 6-keto-PGF1 alpha, PGF2 alpha, PGE2 and PGD2 were detected in gastric mucosa.(ABSTRACT TRUNCATED AT 250 WORDS)
