Abstract

The whole body extracts (WBEs) of 13 common insects from Delhi, namely Musca domestica (house fly); Sitophilus oryzae (rice weevil); Callosobrochous maculatus (pulse beetle); Anopheles stephensi, Culex quinquefasciatus and Aedes aegypti (mosquitoes); Blattella germanica and Periplaneta americana (cockroaches: male, female and nymph); Spodoptera litura and Heliothis armigera (moths), were prepared to evaluate their allergenic significance in patients with allergic bronchial asthma. Intradermal (ID) tests were performed with these WBEs on 75 patients with bronchial asthma and 20 healthy non-allergic volunteers. An ID test was considered positive when the weal diameter was more than twice that of phosphate-buffered saline control and at least 6 mm in size and an erythema of more than 15 mm. In the patients 27.7% of the ID tests performed were total positive (1+ to 4+) as compared to 7.1% in the controls. Ten point two per cent of ID responses were markedly positive in asthmatics (2+ to 4+) as against none in controls. Of the 13 bronchial provocation tests (BPTs) performed on patients giving positive cutaneous responses, eight (61.5%) were positive. Similarly, RASTs were positive in 87.5% of the limited sera tested from the patient...Continue Reading

Asthma

This feed focuses in Asthma in which your airways narrow and swell. This can make breathing difficult and trigger coughing, wheezing and shortness of breath.

Allergy and Asthma

Allergy and asthma are inflammatory disorders that are triggered by the activation of an allergen-specific regulatory t cell. These t cells become activated when allergens are recognized by allergen-presenting cells. Here is the latest research on allergy and asthma.

Atopic Dermatitis

Atopic dermatitis is a chronic inflammatory genetically determined disease of the skin marked by increased ability to form reagin (IgE), with increased susceptibility to allergic rhinitis and asthma, and hereditary disposition to a lowered threshold for pruritus. Discover the latest research on atopic dermatitis here.
