Cutaneous reactivity against histamine skin prick test (Type I) and purified tuberculin protein derivative (Mantoux reaction, Type IV) was studied in eight volunteers under hypnosis. Types I and IV immunoreactivity were modulated by direct suggestion (Type I) and guided imagery (Type IV). The volunteers were highly susceptible subjects, selected by means of the Harvard Group Scale of Hypnotic Susceptibility, Form A.

The effect of psychological pain reduction on the cutaneous inflammatory process was investigated by studying the effect of hypnotically induced analgesia on the flare reaction of cutaneous histamine prick tests. Ten highly hypnotically susceptible volunteers had their cutaneous reactivity against histamine prick tests on both arms measured before hypnosis. Their pain-related brain potentials were measured on the basis of eight argon laser stimulations. These measurements were repeated in the hypnotic condition, where subjects were given repeated suggestions of analgesia in one arm.

Immediate (Type I) hypersensitivity skin reactions to allergens or antigens have been used as immune measures that may be subject to intentional modulation. In preliminary experiments using hypnosis we encountered unacceptably large, uncontrollable variability. A method was subsequently devised in which serial, five-fold dilutions of allergen or histamine were administered to the subject's forearm and reactions were recorded photographically on slide film. Areas were determined by computer-assisted image analysis.

Hypnosis has been used to ameliorate skin test reactivity in studies dating back to the 1930s. This study using modern methodology and statistical analyses sets out to test the hypothesis that it was possible to decrease reactions to histamine by hypnotic suggestion. Five subjects, all asthmatic and untrained in hypnosis, were given three hypnotic sessions where they were asked to control their reactions to histamine administered by the Pepys technique to forearm skin. These sessions were to be compared with three non-hypnotic sessions.

BACKGROUND: The severity of symptoms in asthma and other hypersensitivity-related disorders has been associated with changes in mood but little is known about the mechanisms possibly mediating such a relationship. The purpose of this study was to examine the influence of mood on skin reactivity to histamine by comparing the effects of hypnotically induced emotions on flare and wheal reactions to cutaneous histamine prick tests.

Essential oils have the potential to initiate allergic reactions due to their volatile and skin absorbent nature. Practitioners and aromatherapy teachers need to be aware of the potential for allergies and be equipped to deal with them if they should arise. Two cases are presented of potentially serious reactions that occurred within a learning situation along with a brief literature critique about allergic reactions to essential oils.

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.

Although hypersensitivity to foods is often linked to exacerbations of symptoms of respiratory allergy, no such information is available regarding the foods traditionally considered to play a probable etiological role in respiratory allergy in India, which are in fact quite different from the ones implicated in the West. The present study was undertaken to investigate whether the practice of withholding certain common foods by parents and practitioners of indigenous systems of medicine (i.e.

BACKGROUND: Asthma is a known risk factor for acute ozone-associated respiratory disease. Ozone causes an immediate decrease in lung function and increased airway inflammation. The role of atopy and asthma in modulation of ozone-induced inflammation has not been determined. OBJECTIVE: We sought to determine whether atopic status modulates ozone response phenotypes in human subjects. METHODS: Fifty volunteers (25 healthy volunteers, 14 atopic nonasthmatic subjects, and 11 atopic asthmatic subjects not requiring maintenance therapy) underwent a 0.4-ppm ozone exposure protocol.
