Abstract
Inflammatory bowel disease (IBD) represents chronic recurrent intestinal inflammation resulting from various factors. Crohn’s disease (CD) and ulcerative colitis (UC) have been identified as the two major types of IBD. Currently, most of the drugs for IBD used commonly in the clinic have adverse reactions, and only a few drugs present long-lasting treatment effects. Moreover, issues of drug resistance and disease recurrence are frequent and difficult to resolve. Together, these issues cause difficulties in treating patients with IBD. Therefore, the development of novel therapeutic agents for the prevention and treatment of IBD is of significance. In this context, research on natural compounds exhibiting anti-inflammatory activity could be a novel approach to developing effective therapeutic strategies for IBD. Phytochemicals such as astragalus polysaccharide (APS), quercetin, limonin, ginsenoside Rd, luteolin, kaempferol, and icariin are reported to be effective in IBD treatment. In brief, natural compounds with anti-inflammatory activities are considered important candidate drugs for IBD treatment. The present review discusses the potential of certain natural compounds and their synthetic derivatives in the prevention and treatment of IBD.

Abstract
Peptic ulcers are one of the world's major gastrointestinal disorders, embracing both gastric and duodenal ulcers, and affecting 10% of the world population. The current study aimed to investigate the possible protective effect of tadalafil and pentoxifylline (PTX) on indomethacin-induced peptic ulcers. Male albino rats were divided into five groups: control group; ulcerated group; Indomethacin + Tadalafil, in which animals were pretreated with tadalafil orally before indomethacin; Indomethacin+ PTX, in which animals were pretreated with PTX orally before indomethacin; and Indomethacin + Tadafil + PTX. Indomethacin treatment revealed histopathological changes and ulcer scoring and ulcer index were markedly increased. Serum levels of prostaglandin and heme oxygenase-1 were significantly decreased. The ulcerogenic also induced marked oxidative stress as evident from the increased malondialdehyde, decreased in gastric glutathione content and superoxide dismutase activity, while the gastric myeloperoxidase was increased. Gastric nitric oxide content was decreased and the expression of vascular endothelial growth factor was downregulated while the tumor necrosis factor α (TNF-α) level was dramatically increased. Pretreatment of the ulcerative group by either tadalafil or PTX or their combination improved all these pathological changes. Tadalafil or PTX may have a role in protecting gastric mucosa damage caused by indomethacin which may be useful in the future for the treatment of gastric ulceration.

Abstract
Inflammatory bowel disease (IBD) represents a group of intestinal disorders with self-destructive and chronic inflammation in the digestive tract, requiring long-term medications. However, as many side effects and drug resistance are frequently encountered, safer and more effective agents for IBD treatment are urgently needed. Over the past few decades, a variety of natural alkaloids made of plants or medicinal herbs have attracted considerable interest because of the excellent antioxidant and anti-inflammatory properties; additionally, these alkaloids have been reported to reduce the colonic inflammation and damage in a range of colitic models. In this review paper, we summarize the recent findings regarding the anti-colitis activity of plant-derived alkaloids and emphasize their therapeutic potential for the treatment of IBD; obvious improvement of the colonic oxidative and pro-inflammatory status, significant preservation of the epithelial barrier function and positive modulation of the gut microbiota are the underlying mechanisms for the plant-derived alkaloids to treat IBD. Further clinical trials and preclinical studies to unravel the molecular mechanism are essential to promote the clinical translation of plant-derived alkaloids for IBD.

Abstract
Objective This study was performed to determine the healing effects of pentoxifylline
on molecular responses and protection against severe ischemic damage in the
small intestine. Methods Thirty-six Wistar albino rats were divided into six groups. The superior
mesenteric artery was clamped for 120 minutes, and reperfusion was performed
for 60 minutes. Saline (0.4 mL), pentoxifylline (1 mg/kg), and
pentoxifylline (10 mg/kg) were intraperitoneally administered to the rats in
the C1, P1, and P3 groups, respectively, 60
minutes before ischemia and to the rats in the C2, P2,
and P4 groups, respectively, during reperfusion onset.
Malondialdehyde, myeloperoxidase, tumor necrosis factor alpha, interleukin-1
beta, and interleukin-6 in serum and tissue were measured by enzyme-linked
immunosorbent assay. Intestinal ischemic injury was histopathologically
evaluated by the Chiu score and immunohistochemical staining. Results All serum and tissue molecular responses were significantly blunted in the
pentoxifylline-treated groups compared with the controls. Significant
improvement in ischemic damage was demonstrated in the
pentoxifylline-treated groups by histological grading and
immunohistochemical scoring. Conclusions The protective effects of pentoxifylline were confirmed by molecular
responses and histopathological examination.
