Healing property of the Piper betel phenol, allylpyrocatechol against indomethacin-induced stomach ulceration and mechanism of action

AIM：To evaluate the protective activity of allylpyrocatechol （APC）, the major antioxidant constituent of Piper betel, against the indomethacin-induced stomach ulceration in the rat model and correlates with its antioxidative and mucin protecting properties.METHODS： Male Sprague-Dawley rats were divided into five groups. Normal control rats （group Ⅰ ） were given the vehicle oral dose of gum acacia in distilled water （1 mL per rat）; ulcerated control and treated rats （groups Ⅱ-V） were given a single dose of indomethacin （30 mg/kg body wt.）; group Ⅱ rats were sacrificed 4 h after indomethacin administration; groups Ⅲ-Ⅴ rats were given the vehicle （1 mL per rat） or APC （2 mg/kg body wt.） or misoprostol （1.43 μg/kg body wt.） once daily by oral intubation for 7 d starting from 4 h after the indomethacin administration. After 7 d, the stomach tissues were excised for histological examination and biochemical analysis. RESULTS： Treatment with APC （2 mg/kg body wt per day） and misoprostol （1.43 μg/kg body wt per day） for 7 d could effectively heal the stomach ulceration as revealed from the ulcer index and histopathological studies. Compared to the zero day ulcerated group, treatment with APC and misoprostol reduced the ulcer index by 93.4% and 85.4% respectively （P 〈 0.05）. Both APC and misoprostol accelerated ulcer healing observed in natural recovery （P 〈 0.05）, their respective healing capacities not being significantly different. The healing capacities of APC and misoprostol could be attributed to their antioxidant activity as well as the ability to enhance the rnucin content of the gastric tissues. Compared to the ulcerated untreated rats, those treated with APC and rnisoprostol showed near normal MDA levels, while the protein levels were 86% and 78% of the normal value respectively （P 〈 0.05）. Likewise, both APC and rnisoprostol increased the SOD, catalase, and rnucin levels significantly （P 〈 0.05）, the effect of APC being better. CONCLUSION： APC can protect indomethacin-induced gastric ulceration due to its antioxidative and mucin protecting properties.

Feed Form Affects Growth and Stomach Ulcers in Yearling Horses

Fourteen yearling standardbred horses were used to test the hypothesis that hay and grain fed as a complete total mixed ration （TMR） cube diet （C） would result in greater average daily gain （ADG）, feed efficiency （gain to feed ratio, G/F） and apparent digestibility in horses on the TMR diet compared to horses fed the same weight and proportion of hay cubes and grain fed separately （diet HG）. Both diets consisted of 75% forage and 25% ground oats. The forage in both the plain hay cubes and the complete cubes was 80% alfalfa and 20% endophyte-free tall rescue. An additional hypothesis that stomach ulceration would not differ between horses fed either of the two diet treatments was also tested by comparing upper gastric endoscopies before and after 70 days of feeding the experimental diets. Horses fed diet C had greater ADG （P 〈 0.046） while G/F between the two treatments was not significantly different （P 〉 0.065） but showed a trend to be higher in the horses consuming diet C. Apparent digestibility of dry matter and crude protein was not different between the diet treatments, and no major gastric ulceration was found in horses consuming either diet treatment. The results of this study found that a complete cubed diet of 75% hay and 25% oats did not cause stomach ulceration while achieving an acceptable growth rate in yearling horses.

降钙素基因相关肽在胃溃疡模型小鼠穴位敏化中的作用研究

目的从分子生物学的角度,探讨降钙素基因相关肽(calcitonin gene-related peptide,CGRP)在慢性胃溃疡模型小鼠穴位敏化过程中的作用。方法将C57BL/6小鼠随机分为对照组和模型组,每组15只,将冰乙酸溶液于胃小弯近幽门处注射到胃壁肌层近黏膜下层构建慢性胃溃疡模型,随后在小鼠尾静脉上注射伊文思蓝,观察穴位敏化点的体表分布规律;HE染色法观察胃部组织在造模前后的病理形态变化;通过体表痛敏行为学实验,观察小鼠痛觉阈值的改变;蛋白质印迹法、免疫荧光染色法检测穴位敏化后脊髓、背根神经节(dorsal root ganglion,DRG)和皮肤中的CGRP表达。结果通过向小鼠胃部注射冰乙酸可诱导其形成符合胃溃疡典型病理特征的动物模型;对照组EB渗出点较少,模型组EB渗出点分散于脊髓T_(1)~T_(13)节段支配区域,其中以T_(9)~_(T11)区域最为集中,且其伊文思蓝渗出点压痛阈较造模前显著降低(P<0.01)。穴位敏化后模型组的脊髓、DRG和皮肤中的CGRP蛋白和荧光蛋白阳性表达显著高于对照组(P<0.01)。结论冰乙酸诱导小鼠形成胃溃疡后,其胃部组织病变所对应的体表敏化区、相应的脊髓T9~T11节段和DRG神经元中CGRP表达增高,可能是引起外周和中枢痛觉敏化,使体表局部出现神经源性炎性反应,介导穴位敏化的原因。

Gastrin,somatostatin,G and D cells of gastric ulcer in rats

AIM: To investigate the relationship among gastrin, somatostatin, G and D cells in gastric ulcer and in its healing process in rats. METHODS: Fourty-nine Wistar rats were divided into 7 groups. The gastric ulcer model was induced by acetic acid successfully. The gastrin and the somatostatin in rat plasma, gastric fluid and antral tissue were measured by radioimmunoassay(RIA). G and D cells in antral mucosa were analyzed with polyclonal antibody of gastrin and somatostatin by immunohistochemical method and Quantimet 500 image analysis system. RESULTS: In gastric ulcer, the level of gastrin in plasma, gastric fluid, and antral tissue increased, that of somatostatin declined, and the disorder gradually recovered to the normal level in the healing process. Immunohistochemical technique of G and D cells in antral mucosa demonstrated that the number of G cells increased and that of D cells decreased, both areas of G and D cells declined, the ratio of number and area of G/D increased in gastric ulcer, and the disorder gradually recovered in the healing process. CONCLUSION: In gastric ulcer, the increased gastrin secreted by G cells, the declined somatostatin secreted by D cells, and the disordered G/D cell ratio can lead to gastrointestinal dysfunction.

Association of CagA and VacA presence with ulcer and non-ulcer dyspepsia in a Turkish population

AIM:The mostly known genotypic virulence features,of H.pylori are cytotoxin associated gene A (cagA) and Vacuolating cytotoxin gene A (VacA).We investigated the association of these major virulence factors with ulcer and non-ulcer dyspepsia in our region. METHODS:One hundred and forty two dyspeptic patients were studied (average age 44.8±15.9 years,range 15-87 years,64 males and 78 females).Antral and corpus biopsies were taken for detecting and genotyping of H.pylori.107 patients who were H.pylori positive by histological assessment were divided into three groups according to endoscopic findings:Duodenal ulcer (DU),gastric ulcer (GU) and non-ulcer dyspepsia (NUD).The polymerase chain reaction (PCR) was used to detect CagA and VacA genes of H.pylori using specific primers. RESULTS:H.pyloriwas isolated from 75.4% (107/142) of the patients.Of the 107 patients,66 (61.7%) were cagA- positive and 82 (76.6%) were VacA-positive.CagA gene was positively associated with DU and GU (P<0.01,P<0.02), but not with NUD (P>0.05).Although VacA positivity in ulcer patients was higher than that in NUD group,the difference was not statistically significant (P>0.05). CONCLUSION:There is a significantly positive association between CagA genes and DU and GU.The presence of VacA is not a predictive marker for DU,GU,and NUD in our patients.

Spices, herbal xenobiotics and the stomach: Friends or foes?

Spices and herbal remedies have been used since ancient times to treat a variety of disorders. It has been experimentally demonstrated that spices, herbs, and their extracts possess antimicrobial, anti-inflammatory, antirheumatic, lipid-lowering, hepatoprotective, nephroprotective, antimutagenic and anticancer activities, besides their gastroprotective and anti-ulcer activities. Despite a number of reports on the toxicity of herbs and spices, they are generally accepted as safer alternatives to conventional therapy against gastric ulcers. To this end, it is also believed, that excessive consumption of spices may favor the pathogenesis of gastric and duodenal ulcer and some studies have substantiated this common perception. Based on various in vivo experiments and clinical studies, on the effects of spices and herbs on gastric ulcers, it has indeed been shown that certain spices do possess remarkable anti-ulcer properties mediated by antisecretory, cytoprotective, antioxidant, and anti-Helicobacter pylori effects and mechanisms regulated by nitric oxide, prostaglandins, non-protein sulfhydryl molecules and epidermal growth factor expression. Accordingly, their consumption may attenuate and help prevent peptic ulcer disease. In the present review, the beneficial effects of spices and herbal nutritive components on the gastric mucosa are discussed against the paradigm of their deleterious potential.

Clinical characteristics of peptic ulcer perforation in Korea

AIM To elucidate the epidemiological characteristics and associated risk factors of perforated peptic ulcer(PPU).METHODS We retrospectively reviewed medical records of patients who were diagnosed with benign PPU from 2010 through 2015 at 6 Hallym university-affiliated hospitals.RESULTS A total of 396 patients were identified with postoperative complication rate of 9.1% and mortality rate of 0.8%. Among 174(43.9%) patients who were examined for Helicobacter pylori(H. pylori) infection, 78(44.8%) patients were positive for H. pylori infection, 21(12.1%) were on non-steroidal anti-inflammatory drugs(NSAIDs) therapy, and 80(46%) patients were neither infected of H. pylori nor treated by any kinds of NSAIDs. Multivariate analysis indicated that older age(OR = 1.09, 95%CI: 1.04-1.16) and comorbidity(OR = 4.11, 95%CI: 1.03-16.48) were risk factors for NSAID-associated PPU compared with non-H. pylori, non-NSAID associated PPU and older age(OR = 1.04, 95%CI: 1.02-1.07) and alcohol consumption(OR = 2.08, 95%CI: 1.05-4.13) were risk factors for non-H. pylori, non-NSAID associated PPU compared with solely H. pylori positive PPU.CONCLUSION Elderly patients with comorbidities are associated with NSAIDs-associated PPU. Non-H. pylori, non-NSAID peptic ulcer is important etiology of PPU and alcohol consumption is associated risk factor.

GC/MS-based differential metabolic profiling of human peptic ulcer disease to study Helicobacter pylori-induced metabolic perturbations

Helicobacter pylori infection has been significantly linked to Peptic Ulcer Disease and Gastric Cancer.Metabolomic fingerprinting may offer a principal way of early diagnosis and to understand the molecular mechanism of H.pylori-induced pathogenicity.The rationale of the study is to explore the underlying distinct metabolic mechanisms of H.pylori-induced PUD and to identify potential biomarkers for disease diagnosis and associated risks using Gas chromatography/mass spectrometry.GC/MS-based analytical method was used to compare metabolic profiles of healthy controls(N=20)and peptic ulcer patients(N=45).Acquired metabolomic data were analyzed by constructing a diagnostic model using principal component analysis and a non-parametric two-tailed paired Wilcoxon analysis to identify disease-specific metabolic biomarkers.A total of 75 low-molecular-weight endogenous metabolites were detected during comparative metabolomic analysis of PUD vs.healthy gut tissues,among which 16 metabolites are being proposed to be diagnostic markers of Human PUD.Perturbations related to amino acids,carbohydrates,fatty acids,organic acids,and sterol metabolism were significantly revealed during this differential metabolomic profiling.Results convincingly suggest that metabolic profiles can contribute immensely in early diagnosis of the disease and understanding molecular mechanisms of disease progression for predicting novel drug targets for prophylactic and anaphylactic measures.

CLINICOPATHOLOGICAL STUDY ON 3441 CASES OF BENIGN AND MALIGNANT ULCERS——The National Cooperative Group for Pathological Study on the Canceration of Gastric Ulcer

Resected specimens of benign and malignant gastric ulcers from 3441 cases were studied and compared clinically and pathologically. Among them, 421 cases of malignant ulcer were found. The malignant ulcers differed notably from the ulcerated gastric carcinoma and showed many similarities to the benign chronic gastric ulcer (CGU). The most distinct feature of malignant ulcer was lack of cancerous infiltration and muscular residue in the scar tissue of ulcer base. The existence of this type of ulcer clinically and pathomophologically supports the viewpoint that CGU can undergo malignant change. The rate of malignant change of CGU in this study was 3. 48%.
