Background: Non-steroidal anti-inflammatory drugs are the over-the-counter available medicine and are notorious for their potential in causing peptic ulcer disease. Aspirin in used to treat cardiovascular disease and are commonly prescribed medicine.Methods: 24 healthy albino rats of either sex were purchased and kept at controlled in controlled environment. These are mainly divided into the two groups named as group A and group B having 12 rats in each group. 25 gm of the powdered henna was mixed in 250 ml distilled water. Aspirin was used in the dose of 100 mg/kg drug solution is prepared every day before administration. Animals were sacrificed from each group on day 8th and 15th. Macroscopic ulcer was identified and Fibroblast, inflammatory cells, congested blood vessels were counted. SPSS version 21 was used to statistically analyse the data. P value of ≤0.05 was considered as statistically significant.Results: aspirin group have more ulcer, congested blood vessels, inflammatory infiltrate and increased number of fibroblasts compared to control. The values were statistically significant with p value less than 0.05.Conclusions: gastric ulcer is quite common and it occur because of the imbalance between protecting and aggravating factors. aspirin is a common offender of gastric ulcer because of its common use.

Aim: The study investigated the possible risks associated with gastrointestinal ulcer disease by evaluating the biochemical response of three body organs; heart, kidney and liver, in gastric ulcerated rats. Methodology: Twenty male wistar albino rats were used in the study. Gastric ulcer was induced in rats with single oral dose of 400 mg/kg body weight (b.w.) aspirin, 80 mg/kg b.w. indomethacin and 5 ml/kg b.w. acidified ethanol (40:60 v/v). Blood samples were collected into heparinized bottle and centrifuged at 4000 rpm for 10 mins to obtain the plasma. Gastric tissue, liver, kidney and heart were also collected. Results: Oral administration of 400 mg/kg b.w. aspirin, 80 mg/kg b.w. indomethacin and 5 ml/kg b.w. acidified ethanol caused a remarkable increase in ulcer index. There was observed a significant (p<0.05) reduction in AST and ALT activities in gastric ulceration caused by aspirin (Asp), with no significant (p<0.05) change in total protein (TP) concentration, lactate dehydrogenase and creatine kinase activity. However, there was increase in creatinine and urea concentration. Acidified ethanol and Indomethacin-induced ulcerated rats showed significant (p<0.05) reduction in all other parameters except ALT and lactate dehydrogenase activities which did not show any significant (p<0.05) change. There was also observed a significant (p<0.05) increase in creatine kinase activity in indomethacin-induced ulcerated rats. Conclusion: Overall, the result indicates a link between gastric ulcer and organ toxicity. The use of NSAIDs above the therapeutic doses in the treatment of pains and related illness as well as excess consumption of alcohol is shown to negatively impact the stomach and cause serious damage to different body organs of wistar rats.

Background. Magnolia officinalis Rehd. and Wils. is widely used in Asian countries because of its multiple pharmacological effects. This study investigated the gastroprotective effect and mechanisms of the ethanol extracts from the bark of Magnolia officinalis (MOE) against ethanol-induced gastric mucosal damage in rats. Methods. MOE was prepared by reflux extraction with 70% ethanol, and its main compounds were analyzed by UPLC-Q-Exactive Orbitrap-MS. DPPH, ABTS, and FRAP methods were used to evaluate the antioxidant capacity of MOE in vitro. The gastroprotective effects of MOE were evaluated by the area of gastric injury, H&E (hematoxylin-eosin), and PAS (periodic acid-Schiff). The mechanism was explored by measuring the levels of cytokines and protein in the NF-κB signaling pathway. Results. 30 compounds were identified from MOE, mainly including lignans and alkaloids. MOE presented a high antioxidant activity in several oxidant in vitro systems. Gastric ulcer index and histological examination showed that MOE reduced ethanol-induced gastric mucosal injury in a dose-dependent manner. MOE pretreatment significantly restored the depleted activity of superoxide dismutase (SOD), glutathione peroxidase (GSH-Px) enzymes, reduced malondialdehyde (MDA), and prostaglandin E2 (PGE2) levels in the gastric tissue in rats. In addition, MOE also inhibited the activation of nuclear factor kappa B (NF-κB) pathway and decreased the production of proinflammatory cytokines. Conclusions. The gastroprotective effect of MOE was attributed to the inhibition of oxidative stress and the NF-κB inflammatory pathway. The results provided substantial evidence that MOE could be a promising phytomedicine for gastric ulcer prevention.

Background and Objectives: There is increase prevalence of gastric ulcer in the society, but the drugs that are sensitive for radical cure are not screened with physiologic markers such which affect proper management of the disease. The objective of the study is to relate various sources or organ specific templates: gastrin, histamine and prostaglandin relating with the disease in evaluating the potencies of cimetidine, ranitidine and omeprazole for best choice of the drugs in gastric ulcer disease treatment.Material and Methods: Plasma, gastric and antral prostaglandins, histamine and gastrin levels were studied in ninety-six (96), male and female Swiss albino rats for 28 days, using high performance liquid chromatography.Results: Male and female rats with gastric ulcer treated with cimetidine, omepraszole and ranitidine showed no significant difference (P>0.5) in gastrin and the drug groups in plasma, gastric and antral concentrations. But, there was significant difference (P<0.05) in histamine levels between cimetidine, omeprazole and ranitidine in their gastric and plasma concentration. There was no significant difference (P>0.05) in prostaglandin values between cimetidine, omeprazole and ranitidine. Also there was no significant difference (P>0.05) in gastric and plasma levels of gastrin, histamine and prostaglandin between 7, 14, 21 and 28 days treatment period. But, there was significant difference (P<0.05) in antral concentration of gastrin, histamines and prostaglandin between the drug groups. However, there was no significant difference (P>0.05) in antral gastrin between male and female rats in cimetidine and ranitidine treatment. The three drugs were associated with high levels of gastrin, histamine, low prostaglandin though cimetidine showed higher concentration of prostaglandin.Conclusion: It is concluded that gastrin, histamine and prostaglandin are sensitive indicators in evaluating anti-ulcerogenic drugs efficacies.Janaki Medical College Journal of Medical Sciences (2017) Vol. 5(2): 5-12

This study investigated the gastroprotective effects of diallyl disulfide (DADS), a secondary organosulfur compound derived from garlic ( Allium sativum L.) on experimental model of ethanol (EtOH)-induced gastric ulcer in rats. The antiulcerogenic activity of DADS was evaluated by gross/histopathological inspection, pro-inflammatory cytokines, and lipid peroxidation with antioxidant enzyme activities in the stomach. DADS (100 mg/kg) was administered by oral gavage 2 h prior to EtOH treatment (5 ml/kg). The animals were killed 1 h after receiving EtOH treatment. Pretreatment with DADS attenuated EtOH-induced gastric mucosal injury, as evidenced by decreased severity of hemorrhagic lesions and gastric ulcer index upon visual inspection. DADS also prevented histopathological alterations and gastric apoptotic changes caused by EtOH. An increase in tumor necrosis factor-α (TNF-α) and inducible nitric oxide synthase was observed in the gastric tissues of EtOH-treated rats that coincided with increased serum TNF-α and interleukin 6 levels. In contrast, DADS effectively suppressed production of pro-inflammatory mediators induced by EtOH. Furthermore, DADS prevented the formation of gastric malondialdehyde and the depletion of reduced glutathione content and restored antioxidant enzyme activities, such as catalase, glutathione peroxidase, and glutathione reductase in the gastric tissues of EtOH-treated rats. These results indicate that DADS prevents gastric mucosal damage induced by acute EtOH administration in rats and that the protective effects of DADS may be due to its potent antioxidant and anti-inflammatory activities.
