Anti-inflammatory Effects of Herbal Preparations STW5 and STW5-II in Cytokine-Challenged Normal Human Colon Cells

2016

Inflammatory bowel diseases (IBD) are chronic relapsing intestinal disorders characterized by up-regulation of pro-inflammatory cytokines followed by invasion of immune cells to the intestinal lamina propria. Standard therapies consist of anti-inflammatory or immunosuppressive drugs. Since clinical efficiency is not satisfactory and the established drugs have massive side effects, new strategies to treat IBD are required. Herein, we investigate the protective effect of the fixed combination herbal preparations STW5 and STW5-II and the contribution of the corresponding single components in an in vitro inflammation model. The normal human colon epithelial cell line, NCM460, was treated with S…

Dzīves kvalitāte pacientiem ar iekaisīgo zarnu slimībām Latvijā

2017

Ievads: čūlains kolīts (ČK) un Krona slimība (KS) ir divas galvenās neizārstējamās iekaisīgu zarnu slimības (IZS), kuras bez slimībai specifiskajiem simptomiem būtiski ietekmē arī pacientu dzīves kvalitāti (DzK). Darba mērķi: Novērtēt pacientu ar IZS dzīves kvalitāti, korelāciju starp slimības gaitu un DzK, salīdzināt ČK un KS pacientu dzīves kvalitāti un noskaidrot, vai pastāv korelācija starp DzK un klīniskajiem un demogrāfiskiem rādītājiem. Materiāls un metodes: Tika atlasīti gan stacionēti, gan ambulatori pacienti, kuriem tika lūgts aizpildīt IZS anketu (IZSA), novērtējot sociālos, emocionālos u.c. aspektus, kā arī otru anketu ar vispārīgiem un demogrāfiskiem datiem. Rezultāti: Kopā pēt…

QSAR methods for the discovery of new inflammatory bowel disease drugs

2013

Inflammatory bowel disease (IBD) represents an important class of chronic gastrointestinal tract disease. And although there are already several useful treatments to reduce and control the symptoms, there is still no cure. One drug discovery technique used is the computer-aided (in silico) discovery approach which has largely demonstrated efficacy. Computational techniques, when used in combination with traditional drug discovery methodology, greatly increase the chance of drug discovery in a sustainable and economical fashion.This review aims to provide the most recent and important advances of in silico IBD drug discovery. While this review is mainly focused on QSAR methods, especially th…

Transanal total mesorectal excision for restorative coloproctectomy in an obese high-risk patient with colitis-associated carcinoma

2016

Transanal total mesorectal excision (TaTME) offers great potential for the treatment of malign and benign diseases. However, laparoscopic-assisted TaTME in ulcerative colitis has not been described in more than a handful of patients. We present a 47-year-old highly comorbid female patient with an ulcerative colitis-associated carcinoma of the ascending colon and steroid- refractory pancolitis. A two-stage restorative coloproctectomy including right-sided complete mesocolic excision was conducted. The second step consisted of a successful nerve-sparing TaTME and a handsewn ileal pouch-anal anastomosis. TaTME may extend the possible treatment options in inflammatory bowel disease, especially …

Shikonin promotes intestinal wound healing in vitro via induction of TGF-β release in IEC-18 cells

2013

The intestinal barrier is a complex system with a dynamic structure that is designed for the maintenance of homeostasis in healthy individuals. Ulcerative colitis, one of the main manifestations of inflammatory bowel disease, is characterized by an inadequate and delayed wound healing. Shikonin, the active principle in the root of Lithospermum erythrorhizon, has demonstrated its ability to attenuate dextran sulfate sodium-induced ulcerative colitis in mice. Moreover, the root of L. erythrorhizon has been used in traditional Chinese medicine for treatment of burns, anal ulcers, hemorrhoids and skin wounds. However, the effect of shikonin on intestinal wound healing is unknown. Using an in vi…

Signaling molecules: the pathogenic role of the IL-6/STAT-3 trans signaling pathway in intestinal inflammation and in colonic cancer.

2008

Although the precise etiology of inflammatory bowel diseases (IBD) still remains unclear, considerable progress has been made in the identification of novel signal transduction pathways that elucidate the immunopathogenesis involved in the perpetuation of the inflammatory process. As both ulcerative colitis and Crohn's disease are associated with an increased risk for developing colorectal cancer (CRC) and precancerous dysplastic epithelial changes, further studies have concentrated on finding a common signaling pathway that could serve as a mechanistic link between inflammation and associated colonic cancer in IBD. This review presents the current data concerning the pathogenic role of the…

Mouse models of inflammatory bowel disease.

2007

Animal models of intestinal inflammation are indispensable for our understanding of the pathogenesis of Crohn disease and Ulcerative colitis, the idiopathic forms of inflammatory bowel disease in humans. The clinical appearance of human IBD is heterogeneous, a fact that is also reflected by the steadily increasing number of mouse strains displaying IBD like intestinal alterations. The analysis of these models together with genetic studies in humans greatly enhanced our insights into immunoregulatory processes in the gut and led to the generally accepted hypothesis that a deregulated immune response against components of the intestinal microbiota is critically involved in IBD pathophysiology…

Intestinal anti-inflammatory activity of ellagic acid in the acute and chronic dextrane sulfate sodium models of mice colitis.

2013

Abstract Ethnopharmacological relevance Pomegranate (Punica granatum L.; Lythraceae) has traditionally been used for the treatment of various inflammatory diseases, including ulcerative colitis (UC). Because its fruits and extracts are rich in ellagitannins, which release ellagic acid when hydrolyzed, consumption of pomegranate products is currently being widely promoted for their potential health effects, including the prevention of inflammatory diseases and cancer. To evaluate the anti-inflammatory effects of ellagic acid on dextran sulfate sodium (DSS)-induced acute and chronic experimental colitis in two different strains of mice and to elucidate its possible mechanisms of action. Mater…

Nutrition in inflammatory bowel disease patients

2015

Inflammatory Bowel Diseases (IBD) is a chronic disorder characterized bya relapsing-remitting course, which alternates between active and quiescent states, ultimately impairing a patient's quality of life. The two main types of IBD are Crohn's disease (CD) and ulcerative colitis (UC). CD shows a transmural granulomatous inflammation that can involve any segment of the intestine affecting all layers of the intestinal wall while UC is limited to the mucosa and superficial sub-mucosa of the colon. In physiologial conditions the gut is costantly exposed to various antigens, commensal microflora and pathogens and the inflammatory response is finely balanced. Anyhow in some individuals with genet…
