Background: Visceral hypersensitivity and psychological performance are the main pathophysiological mechanisms of irritable bowel syndrome (IBS). Previous studies have found that cholecystokinin (CCK) can enhance colon movement and that
There is general agreement that chronic diarrhea due to cow's milk allergy (CMA) resolves with a cow's milk-free diet, and that tolerance to cow's milk is achieved by 2 years of life. We have followed for 4 to 10 years, 41 infants with chronic diarrhea due to CMA, who had at onset of diarrhea RAST
UNASSIGNED
Food interaction, including food hypersensitivity, plays a key role in the pathogenesis of irritable bowel syndrome with diarrhea (IBS-D). Since only a few studies have been reported about the relationship between food hypersensitivity and IBS-D, we elucidate the prevalence of serological
This study aimed to present a mouse model of ovalbumin (OVA) induced allergic diarrhea under a sub-barrier system and investigate the development of gut microbiota in this model. Male BALB/c mice were systemically sensitized with OVA or sham-sensitized with saline, and followed by oral OVA
BACKGROUND
Although CD4+ T-cell populations are thought to be involved in the pathophysiology of food allergy and oral tolerance, the role of CD8+ T cells remains uncertain.
OBJECTIVE
We analyzed regulatory effects of adoptively transferred CD8+ T cells on the development of allergic diarrhea in
Recent studies have revealed that various neurotransmitters regulate the immune system via their receptors expressed on the immune cells. Calcitonin gene-related peptide (CGRP), a sensory nerve C-fiber neuropeptide, is also known to have the ability to modulate the functions of immune cells in
BACKGROUND
When sensitized epicutaneously and challenged orally with ovalbumin, Balb/c mice develop allergen-induced diarrhea. As mast cells play important roles in diarrhea, we studied whether allergic diarrhea could be alleviated with imatinib mesylate.
METHODS
Balb/c mice were sensitized and
BACKGROUND
Allergic reactions to food can involve diarrhea, vomiting, nausea and abnormal pain. PG102 has previously been shown to control various factors involved in allergy pathogenesis, including IgE and various Th1 and Th2 cytokines, in vivo as well as in vitro [Park EJ, et al.: J Allergy Clin
Intestinal allergic diseases are initiated by aberrant Th2-type immune responses, including elevation of IgE antibodies (Abs) and infiltration of eosinophils. However, little is known about the role of Peyer's patches (PP) in the control of allergic diseases. Using a mouse model for food allergy, we
Systemically primed BALB/c mice developed severe diarrhea after repeated oral administration of ovalbumin (OVA). Histological analysis demonstrated that dramatic infiltration of eosinophils and mast cells occurred in the large intestine but not in the small intestine of mice with diarrhea.
Atractylodes macrocephala Koidz (AMK) is well-known as a digestive and tonic material and is widely used in traditional Korean herbal medicines. Previously, we found that protein samples obtained from the medicines could induce a preferential stimulation of type 1, rather than type 2, helper T
Food allergies have become increasingly prevalent during the past few decades. Diarrhea is one of the most frequent intestinal symptoms caused by food allergens and is characterized by imbalanced ion exchange and water transfer; however, the underlying mechanism of allergic diarrhea remains unclear.
OBJECTIVE
Although increased mast cells in the gut and their role in visceral hypersensitivity in irritable bowel syndrome have been postulated, this relationship remains unclear. Our aim was to determine whether a relationship exists between the number of mucosal mast cells in the gut and visceral
The incidence of food hypersensitivity and food allergies is on the rise and new treatment approaches are needed. We investigated whether N. sativa, one of its components, thymoquinone, or synthetic opioid receptor (OR)-agonists can alleviate food allergy. Hence, ovalbumin (OVA)-sensitized
BACKGROUND
The clinical manifestations of food allergy include diarrhea and systemic anaphylaxis (shock), which can occur together or by themselves in different subjects. Although ingested food antigens need to be absorbed to induce shock, it is not known whether they need to be absorbed to induce
