The anti-allergic activity of bryonolic acid (1) isolated from the cultured cells of Luffa cylindrica L. (Cucurbitaceae) was compared with that of glycyrrhetinic acid (2), the aglycone of glycyrrhizin from licorice. Compound 1, when administered to rats intraperitoneally at a dose of 600 mg/kg,
BACKGROUND
Although melon is a frequent allergy-eliciting fruit, allergic reactions to melon have rarely been reported.
OBJECTIVE
To evaluate and describe the clinical characteristics of melon allergy in melon-allergic patients.
METHODS
We evaluated patients allergic to melon and a control group of
BACKGROUND
Allergy is a clinical disorder affecting humans worldwide. Allergenic extracts prepared from natural source materials remain heterogeneous in composition and content, but are regularly used for diagnosis and immunotherapy. Recombinant allergens are suitable candidates to use in place of
Plant allergens, being one of the most widespread allergenic substances, are hard to avoid. Hence, their identification and characterization are of prime importance for the diagnosis and treatment of food allergy. The reported allergies to fruits mainly evoke oral allergy syndrome caused by the
Cell suspension cultures of Luffa cylindrica, Citrullus lanatus, and related cucurbitaceous plants accumulate large quantities of bryonolic acid (3 beta-hydroxy-D:C-friedoolean-8-en-29-oic acid) [1], an acidic, pentacyclic triterpene found exclusively in the roots of the intact plants. This compound
BACKGROUND
Few studies have evaluated IgE-mediated hypersensitivity to melon with details of clinical reactions confirmed by double-blind, placebo-controlled, food challenges (DBPCFCs).
OBJECTIVE
We sought to investigate clinical features (type and severity of reactions, age at onset, results of
BACKGROUND
Several studies reported the clinical features of IgE-mediated hypersensitivity after ingestion of melon. Melon allergy is a common IgE-mediated fruit allergy in Iran. This prompted us to investigate immunochemical and molecular properties of the major allergen in melon fruit, to compare
BACKGROUND
The fruit pulp of Luffa cylindrica Roemer (Cucurbitaceae) (LC) has been used to induce hemostasis, resolve phlegm and clear fever in traditional Korean medicine. However, the efficacy of LC has not been examined in atopic dermatitis (AD).
OBJECTIVE
A 70% ethanol extract of LC was
The nature of resistance in Cucumis ficifolius and C. metuliferus to the root-knot nematode, Meloidogyne incognita acrita, was studied under greenhouse conditions. Although as many larvae penetrated the roots of these species as those of the susceptible C. melo, few developed to the adult female
BACKGROUND
Oral allergy syndrome resulted from plant-derived foods is frequent among adults. Allergy to melon (cucumis melo) is one of the most frequent fruit allergies in Iran. Three different major allergens have been found in Cucumis melo that Cuc m 1 (cucumisin) has been identified as the major
BACKGROUND
Melon (Cucumis melo) allergy is one of the most common food allergies, characterized by oral allergy syndrome. To date, two allergen molecules, Cuc m 1 and Cuc m 2, have been fully characterized in melon pulp, but there are few reports about the molecular characteristics of Cuc m
In March 2000, a leaf spot was reported affecting yellow summer squash (Cucurbita pepo) and cantaloupe (Cucumis melo) in commercial fields in Colquitt, Echols, and Grady counties in Georgia. All of the crops affected were reported within a 10-day period, and average temperatures during that time
Phloem vasculature is the route that most plant viruses use to spread widely around the plant. In addition, phloem sap transports signals that trigger systemic defense responses to infection. We investigated the proteome-level changes that occur in phloem sap during virus infection using the 2D-DIGE
Worldwide, more than one-third of the population suffers from allergies. A significant fraction of officially registered allergens originate from the profilin family of proteins. Profilins are small ubiquitous proteins which are found in plants, viruses and various eukaryotes including mammals.
