Effect anti inflammatory and anti obesity of the polyphenolic extracts of carob leaves "Ceratonia siliqua" and cladode "Opuntia ficus-indica"
2018
In the present study, we have investigated the effects of polyphenol-rich infusions from carob leaves and OFI-cladodes on inflammation associated with obesity and dextran sulfate sodium (DSS)-induced ulcerative colitis in Swiss mice. In vitro studies revealed that aqueous extracts of carob leaves and OFI-cladodes exhibited anti-inflammatory properties marked by the inhibition of , TNF-α and nitric oxide (NO) production in lipopolysaccharide (LPS)-stimulated RAW 264.7 cells concomitant with NF-κβ nucleus translocation inhibition. For in vivo investigations, Swiss male mice were subjected to control or high fat diet (HFD). At the 4th week after the start of study, animals received or not 1% i…
Estrogens control inflammation in experimental colitis.
2014
There is now a wealth of experimental evidence indicating that the deficit in endogenous estrogen facilitates the onset of inflammation that can be antagonized by estrogen replacement therapy. This work investigated the role of estrogen in the control of intestinal inflammation in a panel of colitis models, focusing on the morphological changes, the activity of mast cells, the expression of cytokines (IL-1beta, IL-6, and TNF-alpha), fibronectin and reactive oxygen species. Two hundred adult male rats were divided into 4 groups: colitis was induced in Group I and Group II but only the latter was treated with estrogen; Group III received estrogen only, and Group IV saline. Colitis was induced…
INFLAMMATORY BOWEL DISEASE AND INFGERTILITY: ANALYSIS OF LITERATURE AND FUTURE PERSPECTIVES
2021
Background: inflammatory bowel diseases (IBD) are chronic disorders that affect the gastrointestinal tract but which also present extraintestinal manifestations. One of the problems related to IBD is the presence of bothfemale and male infertility. Aim: determine the correlation between IBD and male and female infertility by analyzing the literature. Material and method: studies carried out in the last twenty years have been selected through the PubMed search engine. Only studies were selected that in their conclusions showed a real correlation between IBD and infertility. Results: the first cause of infetility in both sexes is related to the surgical interventions that patients have to fac…
Protective effects of Aphanizomenon Flose-Aquae (AFA) extract on experimental colitis in rat
2018
Inflammatory bowel diseases (IBD) are chronic immune disorders, which necessitate long-term dependence on powerful drugs. Recently, the use of natural product-based therapies has emerged as a promising intervention for IBD. Aphanizomenon flose-aquae (AFA) is a unicellular bluegreen microalgae, traditionally used for its health-enhancing antioxidant and anti-inflammatory properties; we aimed to evaluate its protective effects on animal model of experimental colitis. Colitis was induced in rat by intracolonic instillation of 15 mg of 2,4-dinitrobenzene sulfonic acid (DNBS). Rats received AFA (100 mg/kg/d) by oral route, 4 days before and 6 days after colitis induction. The effects of AFA on D…
Clostridium difficile toxins A and B inhibit human immune response in vitro
1988
Two Clostridium difficile toxins isolated from strain VPI 10463 were tested for their effect on different human T-cell proliferation systems. In mitogen- and antigen-driven T-cell proliferation systems, toxins inhibited the proliferative response in a dose-dependent fashion. In interleukin-2-driven culture systems, no effect of toxins could be found on preactivated T cells. We suspected that monocytes were the influenced cells, since in antigen- and mitogen-driven systems monocytes were necessary for the proliferative response, whereas the interleukin-2-driven system was independent of monocytes. To prove this concept, purified monocytes were treated with toxins. The treatment was found to …
Internal Hernia Masquerading As Necrotizing Enterocolitis
2017
In extremely preterm infants, acute abdominal emergencies are fortunately less common with improving care. Spontaneous intestinal perforation and necrotizing enterocolitis are conditions where emergency surgery is most often needed. Conservative medical management and placement of temporary drain are often used in the initial management. Internal hernia (IH) is an uncommon cause of bowel obstruction in neonates, is difficult to diagnose and unfortunately are found only at autopsy. The presentation in preterm infants, distinction between these conditions, and the need for early diagnosis of IH are discussed.
Early intestinal perforation secondary to congenital mesenteric defects
2016
Abstract Gastrointestinal perforation (GIP) in preterm neonates may be idiopathic, due to necrotizing enterocolitis (NEC), or mechanical obstruction. The predominant cause of GIP in the neonatal period is NEC. Differential diagnosis with congenital malformations, including mesenteric defects leading to internal hernias, is mandatory if the onset is early. We describe two newborns with trans-mesenteric herniation resulting in GIP, and we discuss the presence of possible additional risk factors such as prematurity and predisposing vascular disruption in connective tissue disorders (Ehlers-Danlos syndrome), twinning, and use of assisted reproductive technologies. These cases prompted us to rev…
Neuronal intestinal dysplasia
1987
Findings in 23 children with neuronal intestinal dysplasia (NID) are presented. Twelve children had Hirschsprung's disease that masked the existence of proximal NID. In all cases the diagnosis was established by histological-histochemical examination. Amelioration of symptoms by conservative treatment alone was achieved in 4 children; in 13 cases colostomy was necessary. In 6 patients colon resection was performed: 2 suffered from both colitis and obstruction; the other 4 were treated for obstruction, multiple perforations, persistant adynamia of the left colon, and fistulation. In 9 patients the colostomy was closed. Four of 6 children who did not have sonographic confirmation of motility …
Argentum-quarz solution in the treatment of anorectal fistulas: Is it possible a conservative approach?
2012
Patients suffering from chronic intestinal diseases (Crohn's disease, Ulcerative Colitis, Indeterminate Colitis) are prone to the development of pyogenic complications. These complications are most commonly in the form of perianal or intraabdominal abscesses and/or fistulas. The treatment of these complications are managed differently but, after an initial treatment based on medical or minimally invasive management, the solution of the pathological condition is always achieved by a surgical procedure. In the last few years prospective studies have proposed an alternative conservative therapeutic approach based on application of fibrin glue in the healing of patients with fistulas-in-ano. In…
Endomicroscopy of Colon Pathology
2007
Colorectal cancer is still one of the leading causes of cancer-related death in the Western world. Screening colonoscopy is widely accepted as the gold standard for early diagnosis of cancer. The prognosis for patients with colonic neoplasms is strictly dependent on the depth of infiltration and therefore depends on early detection of pre-invasive and neoplastic changes. Early detection makes it possible to cure the patient by means of immediate endoscopic resection.
