Background. Agarwood has been used for centuries, especially for treatment of gastrointestinal diseases. Earlier studies of our laboratory suggested that agarwood alcohol extracts (AAEs) provided gastric mucosal protection. This study aims to investigate the ameliorative effect of AAEs on ethanol-induced gastric ulcers and its mechanism. Methods. Mice were given agarwood induced by the whole-tree agarwood-inducing technique alcohol extract (WTAAE, 0.71, 1.42, and 2.84 g/kg), wild agarwood induced by axe wounds alcohol extract (WAAE, 2.84 g/kg), and burning-chisel-drilling agarwood alcohol extract (FBAAE, 2.84 g/kg) orally, respectively. After 7 days’ pretreatment with AAEs, the gastric ulcers were induced by absolute ethanol. The ulcer index, gastric histopathology, biochemical parameters, and inflammatory proteins were evaluated. Results. Pharmacological results showed AAEs (1.42 and 2.84 g/kg) reduced the gastric occurrence and ulcer inhibition rates up to more than 60%. AAEs decreased the level of nitric oxide (NO) and increased glutathione (GSH) and superoxide dismutase (SOD) levels. Besides, AAEs decreased the levels of interleukin-1β (IL-1β) and interleukin-6 (IL-6), but the interleukin-10 (IL-10) was upregulated. The expressions of nuclear factor kappa B (NF-κB) and phosphorylated protein 38 (p-P38) were inhibited. The effect of WTAAE was better than that of FBAAE and similar to that of WAAE at the dose of 2.84 g/kg. Conclusions. These results demonstrate that agarwood alleviates the occurrence and development of gastric ulcers via inhibiting oxidation and inflammation.

Gastric ulcer is one of the most common gastrointestinal diseases. Anwulignan (AN) is a major active component of Schisandra sphenanthera Rehd. This study was designed to evaluate the protective effect of AN against the acute gastric ulcer induced by HCl/ethanol in mice. The mice were given HCl/ethanol by gavage to establish an acute gastric ulcer model. Then, the serum and gastric tissue samples were taken for biochemical analyses. The results showed that the pretreatment with AN could significantly reduce the gastric ulcer index (GUI) and increase the ulcer inhibition rate, indicating that AN can protect against gastric ulcers. AN showed its antioxidant roles by decreasing the content of reactive oxygen species (ROS), malondialdehyde (MDA), and 8-hydroxydeoxyguanosine (8-OHdG) and increasing the activity of superoxide dismutase (SOD), catalase (CAT), and glutathione peroxidase (GSH-Px) and anti-inflammatory roles by decreasing the content of tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), interleukin-1β (IL-1β), and myeloperoxidase (MPO) and increasing the content of interleukin-2 (IL-2), interleukin-4 (IL-4), interleukin-10 (IL-10), prostaglandin E2 (PGE2), and nitric oxide (NO) in both serum and gastric tissue. Furthermore, AN also activated the NRF2/ARE signaling pathway and inhibited the MAPK/NF-κB signaling pathway. AN improves the acute gastric ulcer induced by HCl/ethanol in mice, which may be mainly through its antioxidant capacity and anti-inflammatory effect.

Background: The risk factors for patients with cardiovascular diseases and gastrointestinal diseases overlap. Majority of the patients have both problems coexistent. Thus, there is need of medicine that can be used for both the diseases.Methods: Rats weighing 150-250gm of either gender were procured for the study from central animal house. The animals were divided into 7 groups. Control group (Distilled water 2ml), diclofenac sodium (12mg/kg), diltiazem (10mg/kg), diltiazem (30mg/kg), diltiazem (60mg/kg), ranitidine (8mg/kg), ranitidine (16mg/kg). After six hours, scarification of animals was done by cervical dislocation. Size of ulcer, number of gastric ulcers, mean gastric irritancy index, ulcer index, and ulcer scoring were the parameters that were studied.Results: Diltiazem in dose of 10, 30 and 60 mg/kg showed reduction in all parameters in dose dependent manner. Diltiazem (60mg/kg) showed marked reduction in mean diameter of ulcerated surface area (0.46±0.36), number of ulcers (4.10±2.05), size of ulcers (1.07±0.48), total mucosal surface area (7.60±1.38), and total ulcerated surface area (0.263±0.3). Diltiazem (60mg/kg) showed significant reduction of the parameters as compared to other doses of Diltiazem. Also, diltiazem (60mg/kg) was comparable to Ranitidine in all the parameters. Diltiazem (60mg/kg) also showed reduction in average number of ulcers, ulcer index, mean gastric irritancy index and ulcer scoring as compared to diclofenac sodium (12mg/kg).Conclusions: Diltiazem has shown to have ulcer prevention property; this can be useful in patients having concomitant cardiovascular and gastrointestinal problems.

Background: To evaluate the antiulcer activity of ethanolic leaves extract of Saraca indica against ethanol, pylorus ligature and indomethacin in albino rats. Materials and Methods: Ulcer was produced by ethanol, pylorus ligature and indomethacin in albino rats. Five groups (n=6) of rats were orally pre-treated with carboxymethyl cellulose solution, and ranitidine (80 mg/kg) respectively. In ethanol induced ulcer, the animals were treated with 200 and 400 mg/kg b.w. ethanolic leave extracts of Saraca indica in 0.3% CMC solution, 60 minutes before oral administration of absolute ethanol to produce gastric mucosal injury. In indomethacin induced ulcer, the drug was administered orally at the dose of 30 mg/kg b.w. After 7-9 hours of administration of indomethacin (30 mg/kg); the animals were sacrificed with high doses of anesthesia. In the pylorus ligature method, volume of free acidity, gastric secretion, pH and total acidity were estimated. In all three models, the ulcer index and % protection were estimated. Results: The anti ulcer activity of ethanolic leave extracts of Saraca indica in ethanol, indomethacin and pylorus ligature models is evident from the significant (P<0.001) reduction in ulcer index. In pylorus ligature model, significant (P<0.001) reduction in total acidity gastric volume and increase in pH were observed when compared with the standard drug. Conclusion: Ethanolic leave extracts of Saraca indica were found to be significantly protective against ethanol, indomethacin and pylorus ligature induced gastric ulcers in the experimental albino rats. The result obtained suggest that ethanolic leave extracts of Saraca indica possesses significant anti-ulcer activity.

Diabetes mellitus is a metabolic disorder characterized by inflammation, abnormal glycolipid metabolism, insulin resistance, and mitochondrial dysfunction leading to hyperglycemia. The aim of the present investigation was to determine the efficacy of lycopsamine in a rat model of diabetes mellitus to understand its mechanism. Lycopsamine treatment markedly lowered the level of total cholesterol, triglyceride, nonesterified fatty acids, and low-density lipoprotein in diabetic rats. There was also a reduction in interleukin-6, interleukin-10, C-reactive protein, and tumor necrosis factor-α levels. Lycopsamine treatment normalized the metabolism of lipid and glucose, insulin resistance, and body weight of diabetic rats. Findings of immunohistochemical analyses exhibited rise in precipitation of immunocytes in renal cells. Results potentially demonstrated that lycopsamine treatment remarkably reduced the nuclear factor-kappa B level and enhanced the 5′ adenosine monophosphate-activated protein kinase expression. Altogether, administration of lycopsamine suppressed the expression of inflammatory cytokines and attenuated the metabolic symptoms in diabetes mellitus experimental rats.

A 77-year-old Japanese man with bronchial asthma was treated with dupilumab. Dupilumab treatment was discontinued at the patient’s request after two injections separated by a 2-week interval. The blood eosinophil count was elevated, and an esophagogastroduodenoscopy performed 3 months after dupilumab treatment revealed gastric ulcers; subsequently, eosinophilic gastritis was diagnosed from biopsy examinations. The gastric lesions were resolved by steroid administration. This case report underscores that eosinophil-associated gastrointestinal diseases should be considered in the differential diagnosis of gastric lesions occurring in patients who were treated with dupilumab.

Murine rheumatoid arthritis models are often used to investigate the potential therapeutic effects of candidate drugs. The present study has been conducted in order to investigate the therapeutic efficacy of ascidian tunicate extracts in a collagen-induced arthritis DBA1/J mice model. Four types of formulas, ascidian tunicate extracts (ATE), crude ascidian tunicate glycans (ATEC), ascidian tunicate extracts with licorice extracts (ATEL), and crude ascidian tunicate glycans with licorice extracts (ATECL) were orally administered into DBA/1J mice for 3 weeks and paw edema and thickness were evaluated. Changes in inflammatory proteins and cytokines levels were monitored in hind leg tissues by Western blot and quantitative PCR analysis. The oral administration of ascidian tunicate extracts alleviated paw edema and improved the histological hind leg cartilage status. The extracts also reduced the matrix metalloproteinase-9 (MMP-9) protein and prostaglandin E synthase (PGES) levels. In addition, the extracts-treated groups showed increased interleukin-10 (IL-10) levels compared with the non-treated group. These findings suggest that orally administered ascidian tunicate extracts might have potential therapeutic effects for the treatment of rheumatoid arthritis.

Angelica Keiskei

Background: The therapeutic effects of a number of natural products on Inflammatory Bowel Disease (IBD) have recently been examined in detail. The whole herb and roots of Angelica keiskei (Umblliferae) have traditionally been used as a diuretic, to treat gastrointestinal diseases such as gastric ulcers and diarrhea in Japan. Objectives: The present study was performed to investigate the effects of xanthoangelol, a major chalcone of Angelica keiskei roots, on diarrhea and inflammation in the large intestine of IBD model mice. Methods: Xanthoangelol (10 & 25 mg/kg) was orally administered to mice with 3% Dextran Sulfate Sodium (DSS)-induced colitis. Blood samples were collected during the experimental period, subjected to a full blood count test, and colonic cytokine and chemokine levels were measured. Results: Xanthoangelol (25 mg/kg) reduced the Disease Activity Index (DAI) of colitis. It also attenuated DSS-induced reductions in red blood cell and platelet counts as well as Hb and Ht levels. A histological examination of the colon using direct fast scarlet staining showed that xanthoangelol prevented DSS-induced mucosal ulceration and eosinophil infiltration. Xanthoangelol also reduced DSS-induced increases in colonic MCP-1, IL-1β, and TNF-α levels. Conclusions: Xanthoangelol reduced DSS-induced increases in colonic IL-1β, TNF-α, and MCP-1 levels and prevented eosinophil infiltration, which supports its potential as a treatment for IBD.

Resveratrol, a natural stilbenoid, is produced by several plants, especially grape vines. Its strong potency against obesity, metabolic disorders, vascular disease, inflammation, and various cancers has already been reported. Large amounts of wine or grapes need to be consumed to obtain the amount of resveratrol required for biological activity. Pure resveratrol at concentrations as low as 10 μM induces cytotoxicity to normal cells. To overcome these limitations, we prepared genetically modified resveratrol-enriched rice (RR). We previously reported the strong antiaging potential of RR against ultraviolet B/reactive oxygen species-induced toxicity in normal human dermal fibroblasts (NHDF). As aging is characterized by neuroinflammation and neurodegeneration, we further evaluated the role of RR against LPS-induced neuroinflammation. RR inhibited nitric oxide production and the expression of inflammatory proteins such as iNOS and COX-2. RR significantly modulated mitogen-activated protein kinase signaling, activator protein AP-1 signaling, and nuclear factor kappa B (NF-κB) mediated transcription of inflammatory proteins via inhibition of NF-κB translocation, IkB phosphorylation, and proinflammatory cytokine productions such as interleukin IL-6, IL-1β, tumor necrosis factor alpha (TNF-α), and prostaglandin E2 (PGE2). These findings show that the strong antineuroinflammatory effects of RR can be beneficial for aging-mediated neurodegenerative conditions as well as disorders of the central nervous system caused by neuroinflammation.
