  Objective: Inflammatory bowel disease (IBD) is a disorder characterized by chronic inflammation of the gastrointestinal tract and its exact etiopathology is still unclear. Most of the currently available drugs provide the symptomatic improvement, and their long-term use can lead to various unwanted effects also. This study was done to observe the effects of vinpocetine alone and in combination with sulfasalazine on IBD in rats.Methods: Adult Wistar rats of either sex were used (n=36). Experimental colitis was produced by intracolonic administration of acetic acid (10% v/v, 0.20 ml/rat) given per rectally. Rats were divided into six groups (n=6): Group I - normal control (0.9% w/v saline, intracolonic administration + 0.5% w/v carboxymethyl cellulose, i.e., CMC, p.o); Group II - acetic acid (10% v/v, intracolonic administration+0.5% w/v CMC, p.o); Group IIIA - acetic acid + vinpocetine (5 mg/kg, p.o); Group IIIB - acetic acid + vinpocetine (10 mg/kg, p.o); Group IV - acetic acid + sulfasalazine (360 mg/kg, p.o.); Group V - acetic acid + sulfasalazine + vinpocetine (360 mg/kg, p.o. + 5 mg/kg, p.o). The study period was of 15 days in which animals were treated with acetic acid solution on day 1 and treatment was started 4 hrs after the administration of acetic acid till the 14th day. On 15th day, the animals were sacrificed for the investigation of various macroscopic, microscopic, and biochemical parameters.Results: The higher dose of orally administered vinpocetine (10 mg/kg) and combination of sulfasalazine + vinpocetine (360 mg/kg + 5 mg/kg) were found to be the most effective in reducing the severity of mucosal damage which was similar to the reference drug sulfasalazine (360 mg/kg). Both the doses of vinpocetine curtailed the histopathological scores. The combination therapy of sulfasalazine + vinpocetine (360 mg/kg + 5 mg/kg) was equally effective to standard drug but not found to be the most effective treatment. Myeloperoxidase levels were significantly reduced in vinpocetine treated groups as compared to acetic acid control group, while the glutathione levels were increased significantly. Similarly, vinpocetine significantly decreased the malondialdehyde level in the intestinal tissue of the rats with acetic acid induced colitis, and thus the severity of the tissue damage.Conclusion: The results of this study indicated that vinpocetine possesses anti-inflammatory activity and are therapeutically effective in acetic acid induced ulcerative colitis at a dose of 5 mg/kg. More pronounced effects were observed at higher dose, i.e., 10 mg/kg. The combination of sulfasalzine + vinpocetine was also found to be effective as compared to high dose of vinpocetine (10 mg/kg).

Inflammatory bowel disease (IBD) is a chronic condition of the intestine with unknown etiology involving multiple immune, genetic and environmental factors. We were interested to examine the effect of total extract fromZataria multifloraBoiss, a folk medicinal plant on prevention and treatment of experimental IBD.Z. multiflorawas administered (400, 600, 900 p.p.m.) through drinking water to IBD mice induced by intrarectal administration of acetic acid. Prednisolone was used as the standard drug for comparison. Biochemical, macroscopic and microscopic examinations of colon were performed. Biochemical evaluation of inflamed colon was done using assay of myeloperoxidase (MPO) activity and thiobarbituric acid reactive substances (TBARS) concentration as indicators of free radical activity and cell lipid peroxidation. The activity of MPO and lipid peroxidation products (TBARS) increased in acetic acid-treated groups while recovered by pretreatment of animals withZ. multiflora(400–900 p.p.m.) and prednisolone.Z. multiflora(600 and 900 p.p.m.) and prednisolone-treated groups showed significantly lower score values of macroscopic and microscopic characters when compared with the acetic acid-treated group. The beneficial effect ofZ. multiflora(900 p.p.m.) was comparable with that of prednisolone. The antioxidant, antimicrobial and anti-inflammatory potentials ofZ. multifloramight be the mechanisms by which this herbal extract protects animals against experimentally induced IBD. Proper clinical investigation should be carried out to confirm the activity in human.

Abstract Objectives Although bowel symptoms are often predominant, inflammatory bowel disease (IBD) patients can have several oral manifestations. The aim of this study was to investigate the prevalence of dental caries and periodontal disease in patients with Crohn’s disease (CD) and ulcerative colitis (UC) compared to an age and gender-matched control group of patients without IBD. Material and methods The DMFT (Decayed, Missing, Filled Teeth) scores and the DPSI (Dutch Periodontal Screening Index) of 229 IBD patients were retrieved from the electronic health record patient database axiUm at the Academic Centre for Dentistry Amsterdam (ACTA) and were compared to the DMFT scores and DPSI from age and gender-matched non-IBD patients from the same database. Results The total DMFT index was significantly higher in the IBD group compared to the control group. When CD and UC were analyzed separately, a statistically significant increased DMFT index was observed in CD patients but not in UC patients. The DPSI did not differ significantly between the IBD and non-IBD groups for each of the sextants. However, in every sextant, IBD patients were more frequently edentulous compared to the control patients. Conclusion CD patients have significantly more dental health problems compared to a control group. Periodontal disease did not differ significantly between IBD and non-IBD groups as determined by the DPSI. Clinical relevance It is important that IBD patients and physicians are instructed about the correlation between their disease and oral health problems. Strict oral hygiene and preventive dental care such as more frequent checkups should be emphasized by dental clinicians.

Összefoglaló. Gyulladásos bélbetegségben (IBD) a fájdalomérzés komplex szomatikus és pszichés jelenség. Ez utóbbi komponens pontosabb megértése segíthet a megfelelő kezelési stratégia megállapításában. A szorongásos hangulati zavarok és egyes maladaptív viselkedési minták (dohányzás és alkoholfogyasztás) előfordulási gyakorisága jól dokumentált IBD-ben, a kannabiszhasználat hatása ugyanakkor kevésbé ismert. A szerzők szisztematikus áttekintést végeztek annak megértéséhez, hogy vajon magasabb-e a marihuánahasználat gyakorisága felnőtt IBD-s betegek között egészséges kontrollpopulációhoz viszonyítva, és ha igen, akkor melyek a szerhasználat legfontosabb jellemzői. A kutatási periódust szándékosan az elmúlt 7 évre korlátoztuk, ugyanis 2013-tól jelentős változások álltak be a kannabinoidok jogi és orvosi megítélésében az USA-ban. Öt elsődleges és több másodlagos adatbázisban kutattunk előre meghatározott kulcsszavak segítségével 2013 óta teljes szöveggel megjelent, angol nyelvű felnőtt IBD-s populációt vizsgáló epidemiológiai tanulmányok vonatkozásában. 143 rekord közül 7 cikk felelt meg a beválogatási kritériumoknak. Eredményeink szerint a kannabiszhasználat gyakorisága IBD-ben szenvedő felnőtt betegek körében valószínűleg magasabb, mint a kontrollpopulációban: a „valaha, bármikor” használók aránya 54–70% között változott (szemben a 46–60% gyakorisággal a kontrollcsoportban), míg az „aktív használók” esetén a gyakoriság 6,8–25% között változott (vs. a kontrollcsoportban tapasztalt 8,6–14%-kal). A prevalenciaadatok széles variabilitása arra utal, hogy a beválogatott epidemiológiai tanulmányok valószínűleg vagy nem voltak megfelelően tervezve, vagy jelentős heterogenitással bírtak. A pszichés tényezők ellentmondásos mintája azt sugallja, hogy a kannabinoidok egyes esetekben ronthatták, más esetben valószínűleg javították bizonyos prominens tünetek megélését. Javasoljuk ezért, hogy a valós prevalencia megállapítása érdekében a keresztmetszeti vizsgálatok mellé ismételt pszichometriai vizsgálatokon alapuló vizsgálatok is bekerüljenek a további kutatásba. Orv Hetil. 2021; 162(12): 443–448. Summary. Pain perception in inflammatory bowel disease (IBD) is beyond a purely somatic process. In-depth understanding of psychologic elements might enable more effective management in this patient group. Anxiety disorders and certain maladaptive coping strategies like smoking and alcohol consumption are well-documented in IBD, unlike the scarcely researched cannabis use. The authors designed a systematic review, to investigate if the prevalence of cannabis use is higher in IBD that in unselected controls. The research window was intentionally set to cover for the past 7 years, as in 2013 major legislative changes took place in the cannabis decriminalisation process in the United States. 5 primary and several secondary databases were researched with a pre-formulated algorithm registered at PROSPERO for full text epidemiological studies published in English language involving adult IBD patients. Out of 143 records, 7 articles met the in/exclusion criteria. Our results suggest that cannabis use among adult patients with IBD is likely to be higher than in the unselected control population. The proportion of “ever” users varied from 54% to 70% (vs. 46–60% in the control group); and for ‘active users’, the prevalence ranged between 6.8% to 25% (vs. 8.6–14% in the control group). The wide variability in prevalence data suggests that the selected epidemiological studies were either inappropriately designed or were too heterogeneous (or both). The contradictory pattern of psychological factors suggests that cannabinoids might improve or worsen IBD depending on case by case basis. We therefore opine that in addition to cross-sectional papers, studies based on repeated psychometric analysis are needed to establish the real prevalence and inform cannabinoid prescription and holistic management in inflammatory bowel disease.

The objective of the study was to ascertain antioxidant, anti-inflammatory and cytokine gene regulation activity of Holarrhena antidysenterica (HA) in dinitrobenzene sulfonic acid (DNBS) induced inflammatory bowel disease (IBD) in rats. Sprague Dawley rats were divided into 6 groups, Group I (normal), Group II (50% ethanol intracolonically on 11th day), Group III (Model). Group IV to VI were given standard drug 5-amino salicylic acid (5-ASA) (100mg/kg) and hydromethanolic extract of Holarrhena antidysenterica (MEHA) 450 mg/kg and MEHA 600 mg/kg respectively for 18 days once p.o. Colitis was induced with DNBS (180mg/kg in 50% ethanol) intracolonically in animals of Group III-VI on 11th day. Body weight, food & water intake and stool consistency of each group was noted. On 18th day, blood was collected for cortisol estimation. Colon length and weight was measured. Cytokine gene expression studies of colon in group I, II, III, IV and VI was done using Real Time RT-PCR. Colon histopathology, Disease Activity Index (DAI) and Colon Mucosal Disease index (CMDI) parameters were studied. Nitric oxide (NO), malondialdehyde (MDA), myeloperoxidase (MPO) and superoxide dismutase (SOD) were estimated in colon homogenate. DNBS model control showed significant reduction in body weight, water and food intake, SOD, colon length and significant increase in stool consistency, colon weight, MDA, MPO, NO, CMDI, DAI, cortisol, IL-4, IL-6, IL-12 and IFN-gamma cytokines gene expression. Pretreatment with 5-ASA (100mg/kg) and MEHA (450 and 600 mg/kg) significantly reversed the above. MEHA reduced severity of IBD induced by DNBS through its anti-inflammatory, antioxidant and gene modulatory activity.

Abstract Purpose Our previous studies demonstrated that mature adipocyte-derived dedifferentiated fat (DFAT) cells possess similar multipotency as mesenchymal stem cells. Here, we examined the immunoregulatory potential of DFAT cells in vitro and the therapeutic effect of DFAT cell transplantation in a mouse inflammatory bowel disease (IBD) model. Methods The effect of DFAT cell co-culture on T cell proliferation and expression of immunosuppression-related genes in DFAT cells were evaluated. To create IBD, CD4+CD45RBhigh T cells were intraperitoneally injected into SCID mice. One week later, DFAT cells (1 × 105, DFAT group) or saline (Control group) were intraperitoneally injected. Subsequently bodyweight was measured every week and IBD clinical and histological scores were evaluated at 5 weeks after T cell administration. Results The T cell proliferation was inhibited by co-cultured DFAT cells in a cell density-dependent manner. Gene expression of TRAIL, IDO1, and NOS2 in DFAT cells was upregulated by TNFα stimulation. DFAT group improved IBD-associated weight loss, IBD clinical and histological scores compared to Control group. Conclusion DFAT cells possess immunoregulatory potential and the cell transplantation promoted recovery from colon damage and improved clinical symptoms in the IBD model. DFAT cells could play an important role in the treatment of IBD.

Purpose: To investigate the effects of an aqueous extract of unpolished dark purple glutinous Thai rice, variety Luem pua (LP), in two rat models of inflammatory bowel disease (IBD). Methods: Polyphenolic compounds content were determined by HPLC methods and antioxidant activities by DPPH and FRAP assays of the LP extract. The effect of the LP extract at 5 g/kg/day were evaluated in two rat models of IBD that included acetic acid and indomethacin induced IBD. On each day of treatment, changes of body weight, stool consistency and stool blood were scored and expressed as disease activity index (DAI). At the end of the experiments, the animals were euthanized. Colon length and spleen weight were determined, and the degree of inflammation of the colon was scored. Results: Rats in both models of IBD (acetic acid- and indomethacin-induced IBD), exhibited significant increases in DAI, macroscopic inflammation scores and spleen weights, while the lengths of colon were decreased. Pretreatment with LP extract attenuated the disease severity in both models as seen by the reverse of all observed altered parameters. Conclusion: These data suggest that LP extract might be beneficial in preventing and/or treating IBD. Keywords: Inflammatory bowel disease (IBD), Dark purple glutinous rice Var.
