We investigated the effects of the water soluble fraction of Terminalia chebula (Combretaceae) (WFTC) on systemic and local anaphylaxis. WFTC administered 1h before compound 48/80 injection inhibited compound 48/80-induced anaphylactic shock 100% with doses of 0.01-1.0 g/kg. When WFTC was administered 5 or 10 min after compound 48/80 injection, the mortality also decreased in a dose-dependent manner. Passive cutaneous anaphylaxis was inhibited by 63.5+/-7.8% by oral administration of WFTC (1.0 g/kg).

Allergic rhinitis, also known as hay fever, rose fever or summer catarrh, is a major challenge to health professionals. A large number of the world's population, including approximately 40 million Americans, suffers from allergic rhinitis. A novel, botanical formulation (Aller-7) has been developed for the treatment of allergic rhinitis using a combination of extracts from seven medicinal plants, including Phyllanthus emblica, Terminalia chebula, T. bellerica, Albizia lebbeck, Piper nigrum, Zingiber officinale and P. longum, which have a proven history of efficacy and health benefits.

Cell adhesion molecule 1 (CADM1), expressed by human lung mast cells (HLMCs), mediates their adhesion to airway smooth muscle (ASM), and contributes to ASM-dependent HLMC proliferation and survival. CADM1 is expressed in alternatively spliced isoforms, but those present in HLMCs and their function are not known. We cloned three functional and one cryptic non-functional isoform with alternative splicing between exons 7/11 and 1/2, respectively, from HLMCs and human MC lines (HMC-1 and LAD2).

Studies were conducted on the decoction of the bark of Albizzia lebbeck which has been in use by Ayurvedic physicians for bronchial asthma and eczema. The effect of A. lebbeck was studied on the degranulation rate of sensitized peritoneal mast cells of albino rats when challenged with antigen (horse serum). Triple vaccine was used as adjuvant. Disodium cromoglycate (DCG) and prednisolone were used for comparison. Drugs were given during the first or second week of sensitization and the mast cells studied at the end of the second or third week.

The widely known tree Abies pindrow (Talisapatra) (family: Pinaceae), famous for its diverse clinical uses in Ayurvedic medicines, was investigated to rationalise some of the ancient claims. The petroleum ether (PE), benzene (BE), chloroform (CE), acetone (AE) and ethanol (EE) extracts of A. pindrow leaf were found to have mast cell stabilizing action in rats. The EE, AE and BE extracts offered bronchoprotection against histamine challenge in guinea-pigs. The BE, CE and PE extracts had protective role in aspirin-induced ulcer in rats.

Elaeocarpus sphaericus (Syn: E. ganitrus), in Ayurvedic Medicine commonly known as Rudraksha is known to have wide range of pharmacological activities. We reported previously the protective action of E. sphaericus in experimental bronchial asthma. The present study on rat mesenteric mast cell was undertaken to investigate the effect of E. sphaericus fruits on autacoid release. The petroleum ether (PE), benzene (BE), chloroform (CE), acetone (AE) and ethanol (EE) extracts of E. sphaericus fruits were found to have mast-cell stabilizing activity, substantiating the efficacy of E.

Allium cepa (Family Liliaceae) is a reputed Indian medicinal herb that is prescribed as an effective remedy for several ailments in the Ayurvedic system of medicine. The aim of this study was to evaluate its efficacy against various events responsible for Type I allergic reactions. A herbal fraction (ALC-02) from A. cepa (bulb) inhibited histamine release and attenuated intracellular calcium levels in Compound 48/80-induced rat peritoneal mast cells. It also prevented Compound 48/80-mediated systemic anaphylaxis while lowering histamine levels in plasma.

CONTEXT: Decoctions of Baliospermum montanum Müll. Arg. (Euphorbiaceae) leaves are reported to be useful in the treatment of asthma and other respiratory complications in the Ayurvedic system. OBJECTIVE: To evaluate the mast cell stabilization and antihistaminic activities of the chloroform (BMLC) and ethanol (BMLE) extracts of the leaves of Baliospermum montanum.

Allergy is an acquired hypersensitivity reaction of the immune system mediated by cross-linking of the allergen-specific IgE-bound high-affinity IgE receptors, leading to immediate mast cell degranulation. Rottlerin is an active molecule isolated from Mallotus philippinensis, a medicinal plant used in Ayurvedic Medicine System for anti-allergic and anti-helminthic treatments. The present study investigated potential anti-allergic effects of rottlerin in animal models of IgE-dependent anaphylaxis and the anti-allergic mechanisms of action of rottlerin in mast cells.

BACKGROUND: Maternal allergy is believed to be a risk factor for peanut allergy (PNA) in children. However, there is no direct evidence of maternal transmission of PNA susceptibility, and it is unknown whether maternal peanut exposure affects the development of PNA in offspring. OBJECTIVE: To investigate the influence of maternal PNA on offspring reactions to the first peanut exposure, and whether maternal low-dose peanut exposure during pregnancy and lactation influences these reactions and peanut sensitization in a murine model.
